Qt3D - Import gltf and play animation - qt

I'm currently struggling to play the animation of a gltf-file with Qt3D/QML.
Model I want to use:
https://sketchfab.com/3d-models/plane-cedc8a07370747f7b0d14400cdf2faf9
Code I have so far:
Entity {
id: root
Transform {
id: planeTransform
scale: 0.1
}
components: [
planeClip,
planeTransform,
planeScene
]
SceneLoader{
id:planeScene
source: "qrc:/Modells/3DModelle/plane/scene.gltf"
}
AnimationClipLoader{
id: planeClipLoader
source: "qrc:/Modells/3DModelle/plane/scene.gltf"
}
ClipAnimator{
id: planeClip
clip: planeClipLoader
channelMapper: ChannelMapper {
mappings: [ ] // Dont know where to get this
}
loops: Animation.Infinite
running: true
}
}
I use the SceneLoader to check if the gltf can be even loaded (it works, I can see the plane).
But I'm struggling to start the animation because I don't know where I get the ChannelMapper from.
When I open the file with 3DViewer on Windows, it plays the Animation correctly, so I suppose it should work without much insider knowledge of the file itself.
Anyone here familiar with playing gltf animations?
Thanks for the help!

To do this you need to traverse the tree of Entity(s) build by SceneLoader and find the appropriate component to initialize ClipAnimator with.
It's going to look something like this:
SceneLoader {
id: planeScene
source: "qrc:/Modells/3DModelle/plane/scene.gltf"
onStatusChanged: {
console.log("SceneLoader status=" + status);
if (status != SceneLoader.Ready)
return;
// retrieve a list of all the Entity(s) in the scene
var entityNames = planeScene.entityNames();
console.log("SceneLoader: entityNames=" + entityNames);
// traverse the Entity tree
for (var i = 0; i < entityNames.length; ++i) {
var entityName = entityNames[i];
var entityVar = planeScene.entity(entityName);
console.log("SceneLoader: entity=" + entityName + " components.length=" + entityVar.components.length);
// iterate on the components of this Entity
for (var j = 0; j < entityVar.components.length; ++j) {
var cmp = entityVar.components[j];
if (!cmp)
continue;
var cmp_class = cmp.toString();
console.log("SceneLoader: -> " + cmp_class);
// compare the type of this component to whatever type
// you are looking for. On this silly example, its QPhongMaterial:
if (cmp_class.indexOf("QPhongMaterial") >= 0) {
// initialize ClipAnimator with this data
}
}
}
}
}
I'm sharing the generic procedure here as I don't have a way to test this right now and figure out the data type you need to initialize ClipAnimator correctly.

SwiftUI: how to handle BOTH tap & long press of button?

I have a button in SwiftUI and I would like to be able to have a different action for "tap button" (normal click/tap) and "long press".
Is that possible in SwiftUI?
Here is the simple code for the button I have now (handles only the "normal" tap/touch case).
Button(action: {self.BLEinfo.startScan() }) {
Text("Scan")
} .disabled(self.BLEinfo.isScanning)
I already tried to add a "longPress gesture" but it still only "executes" the "normal/short" click. This was the code I tried:
Button(action: {self.BLEinfo.startScan() }) {
Text("Scan")
.fontWeight(.regular)
.font(.body)
.gesture(
LongPressGesture(minimumDuration: 2)
.onEnded { _ in
print("Pressed!")
}
)
}
Thanks!

I tried many things but finally I did something like this:
Button(action: {
}) {
VStack {
Image(self.imageName)
.resizable()
.onTapGesture {
self.action(false)
}
.onLongPressGesture(minimumDuration: 0.1) {
self.action(true)
}
}
}
It is still a button with effects but short and long press are different.
Combining a high priority gesture and a simultaneous gesture should do the trick.
Button(action: {})
{
Text("A Button")
}
.simultaneousGesture(
LongPressGesture()
.onEnded { _ in
print("Loooong")
}
)
.highPriorityGesture(TapGesture()
.onEnded { _ in
print("Tap")
})
Found this a handy pattern when interacting with other views as well.
I just discovered that the effect depends on the order of the implementation. Implementing the detection of gestures in the following order it seems to be possible to detect and identify all three gestures:
handle a double tap gesture
handle a longPressGesture
handle a single tap gesture
Tested on Xcode Version 11.3.1 (11C504)
fileprivate func myView(_ height: CGFloat, _ width: CGFloat) -> some View {
return self.textLabel(height: height, width: width)
.frame(width: width, height: height)
.onTapGesture(count: 2) {
self.action(2)
}
.onLongPressGesture {
self.action(3)
}
.onTapGesture(count: 1) {
self.action(1)
}
}
Here is my implementation using a modifier:
struct TapAndLongPressModifier: ViewModifier {
#State private var isLongPressing = false
let tapAction: (()->())
let longPressAction: (()->())
func body(content: Content) -> some View {
content
.scaleEffect(isLongPressing ? 0.95 : 1.0)
.onLongPressGesture(minimumDuration: 1.0, pressing: { (isPressing) in
withAnimation {
isLongPressing = isPressing
print(isPressing)
}
}, perform: {
longPressAction()
})
.simultaneousGesture(
TapGesture()
.onEnded { _ in
tapAction()
}
)
}
}
Use it like this on any view:
.modifier(TapAndLongPressModifier(tapAction: { <tap action> },
longPressAction: { <long press action> }))
It just mimics the look a button by scaling the view down a bit. You can put any other effect you want after scaleEffect to make it look how you want when pressed.
I had to do this for an app I am building, so just wanted to share. Refer code at the bottom, it is relatively self explanatory and sticks within the main elements of SwiftUI.
The main differences between this answer and the ones above is that this allows for updating the button's background color depending on state and also covers the use case of wanting the action of the long press to occur once the finger is lifted and not when the time threshold is passed.
As noted by others, I was unable to directly apply gestures to the Button and had to apply them to the Text View inside it. This has the unfortunate side-effect of reducing the 'hitbox' of the button, if I pressed near the edges of the button, the gesture would not fire. Accordingly I removed the Button and focused on manipulating my Text View object directly (this can be replaced with Image View, or other views (but not Button!)).
The below code sets up three gestures:
A LongPressGesture that fires immediately and reflects the 'tap' gesture in your question (I haven't tested but this may be able to replaced with the TapGesture)
Another LongPressGesture that has a minimum duration of 0.25 and reflect the 'long press' gesture in your question
A drag gesture with minimum distance of 0 to allow us to do events at the end of our fingers lifting from the button and not automatically at 0.25 seconds (you can remove this if this is not your use case). You can read more about this here: How do you detect a SwiftUI touchDown event with no movement or duration?
We sequence the gestures as follows: Use 'Exclusively' to combine the "Long Press" (i.e. 2 & 3 above combined) and Tap (first gesture above), and if the 0.25 second threshold for "Long Press" is not reached, the tap gesture is executed. The "Long Press" itself is a sequence of our long press gesture and our drag gesture so that the action is only performed once our finger is lifted up.
I also added code in the below for updating the button's colours depending on the state. One small thing to note is that I had to add code on the button's colour into the onEnded parts of the long press and drag gesture because the minuscule processing time would unfortunately result in the button switching back to darkButton colour between the longPressGesture and the DragGesture (which should not happen theoretically, unless I have a bug somewhere!).
You can read more here about Gestures: https://developer.apple.com/documentation/swiftui/gestures/composing_swiftui_gestures
If you modify the below and pay attention to Apple's notes on Gestures (also this answer was useful reading: How to fire event handler when the user STOPS a Long Press Gesture in SwiftUI?) you should be able to set up complex customised button interactions. Use the gestures as building blocks and combine them to remove any deficiency within individual gestures (e.g. longPressGesture does not have an option to do the events at its end and not when the condition is reached).
P.S. I have a global environment object 'dataRouter' (which is unrelated to the question, and just how I choose to share parameters across my swift views), which you can safely edit out.
struct AdvanceButton: View {
#EnvironmentObject var dataRouter: DataRouter
#State var width: CGFloat
#State var height: CGFloat
#State var bgColor: Color
#GestureState var longPress = false
#GestureState var longDrag = false
var body: some View {
let longPressGestureDelay = DragGesture(minimumDistance: 0)
.updating($longDrag) { currentstate, gestureState, transaction in
gestureState = true
}
.onEnded { value in
print(value.translation) // We can use value.translation to see how far away our finger moved and accordingly cancel the action (code not shown here)
print("long press action goes here")
self.bgColor = self.dataRouter.darkButton
}
let shortPressGesture = LongPressGesture(minimumDuration: 0)
.onEnded { _ in
print("short press goes here")
}
let longTapGesture = LongPressGesture(minimumDuration: 0.25)
.updating($longPress) { currentstate, gestureState, transaction in
gestureState = true
}
.onEnded { _ in
self.bgColor = self.dataRouter.lightButton
}
let tapBeforeLongGestures = longTapGesture.sequenced(before:longPressGestureDelay).exclusively(before: shortPressGesture)
return
Text("9")
.font(self.dataRouter.fontStyle)
.foregroundColor(self.dataRouter.darkButtonText)
.frame(width: width, height: height)
.background(self.longPress ? self.dataRouter.lightButton : (self.longDrag ? self.dataRouter.brightButton : self.bgColor))
.cornerRadius(15)
.gesture(tapBeforeLongGestures)
}
}
This isn't tested, but you can try to add a LongPressGesture to your button.
It'll presumably look something like this.
struct ContentView: View {
#GestureState var isLongPressed = false
var body: some View {
let longPress = LongPressGesture()
.updating($isLongPressed) { value, state, transaction in
state = value
}
return Button(/*...*/)
.gesture(longPress)
}
}
Kevin's answer was the closest to what I needed. Since ordering the longPressGesture before the tapGesture broke ScrollViews for me, but the inverse made the minimumDuration parameter do nothing, I implemented the long press functionality myself:
struct TapAndLongPressModifier: ViewModifier {
#State private var canTap = false
#State private var pressId = 0
let tapAction: (()->())
let longPressAction: (()->())
var minimumDuration = 1.0
func body(content: Content) -> some View {
content
.onTapGesture {
if canTap {
tapAction()
}
}
.onLongPressGesture(
minimumDuration: 1.0,
pressing: { (isPressing) in
pressId += 1
canTap = isPressing
if isPressing {
let thisId = pressId
DispatchQueue.main.asyncAfter(deadline: .now() + minimumDuration) {
if thisId == pressId {
canTap = false
longPressAction()
}
}
}
},
// We won't actually use this
perform: {}
)
}
}
just do this:
the first modifier should be onLongPressGesture(minumumDuration: (the duration you want))
and the following mondifier should be onLongPressGesture(minimumDuration: 0.01) <- or some other super small numbers
this works for me perfectly
As a follow up, I had the same issue and I tried all of these answers but didn't like how they all worked.
I ended up using a .contextMenu it was way easier and produces pretty much the same effect.
Check link here
and here is an example
UPDATE:
As of iOS 16, .contextMenu has been depreciated. So I ended up using .simultaneousGesture on the Button, not the content in the button's label block.
i.e.
Button {
// handle Button Tap
} label: {
// button label content here
}
.simultaneousGesture(LongPressGesture()
.onEnded { _ in
// handle long press here
}
)
This still preserves the button animations as well.
Note tested before iOS 16 however.
Thought I'd post back on this, in case anyone else is struggling. Strange that Apple's default behaviour works on most controls but not buttons. In my case I wanted to keep button effects while supporting long press.
An approach that works without too much complexity is to ignore the default button action and create a simultaneous gesture that handles both normal and long clicks.
In your view you can apply a custom long press modifier like this:
var body: some View {
// Apply the modifier
Button(action: self.onReloadDefaultAction) {
Text("Reload")
}
.modifier(LongPressModifier(
isDisabled: self.sessionButtonsDisabled,
completionHandler: self.onReloadPressed))
}
// Ignore the default click
private func onReloadDefaultAction() {
}
// Handle the simultaneous gesture
private func onReloadPressed(isLongPress: Bool) {
// Do the work here
}
My long press modifier implementation looked like this and uses the drag gesture that I found from another post. Not very intuitive but it works reliably, though of course I would prefer not to have to code this plumbing myself.
struct LongPressModifier: ViewModifier {
// Mutable state
#State private var startTime: Date?
// Properties
private let isDisabled: Bool
private let longPressSeconds: Double
private let completionHandler: (Bool) -> Void
// Initialise long press behaviour to 2 seconds
init(isDisabled: Bool, completionHandler: #escaping (Bool) -> Void) {
self.isDisabled = isDisabled
self.longPressSeconds = 2.0
self.completionHandler = completionHandler
}
// Capture the start and end times
func body(content: Content) -> some View {
content.simultaneousGesture(DragGesture(minimumDistance: 0)
.onChanged { _ in
if self.isDisabled {
return
}
// Record the start time at the time we are clicked
if self.startTime == nil {
self.startTime = Date()
}
}
.onEnded { _ in
if self.isDisabled {
return
}
// Measure the time elapsed and reset
let endTime = Date()
let interval = self.startTime!.distance(to: endTime)
self.startTime = nil
// Return a boolean indicating whether a normal or long press
let isLongPress = !interval.isLess(than: self.longPressSeconds)
self.completionHandler(isLongPress)
})
}
}
Try this :)

How to use QML Model, Delegate, Repeater, View?

I have json result as shown below. In my QML project I want to parse the json which I did help of How to show data in QML json request . Now I want to set 4 flag. Local flag, USA, UK and Europe in one row. And I will add as shown below.
My question is how to use QML Model, Delegate, Repeater, View? And which view is beter solution to have?
{ "tarih": "20171212",
"currency": {
"usa": { "buy": "3,7900", "sell": "3,8800", "e_buy": "3,7900" },
"stg": { "buy": "5,0700", "sell": "5,1650", "e_buy": "5,0700" },
"eur": { "buy": "4,4700", "sell": "4,5600", "e_buy": "4,4700" }
}
}
thank you
UPDATE:
Easiest way to do it is this:
Parse json with;
(var result = JSON.parse(request.responseText))
And I get items with this:
(getUsaBuy.text = result.currency.usa.buy)
I motife my original post from How to show data in QML json request.
Running Code:
if (request.readyState === XMLHttpRequest.DONE) {
if (request.status && request.status === 200) {
var result = JSON.parse(request.responseText)
// BUY
textSTG_BUY.text = **result.currency.stg.buy**
// SELL
textSTG_SELL.text = **result.currency.stg.sell**
}
else {
console.log("Log:", request.status, request.statusText)
}
}

Asynchronous update of nodes properties after the graph is rendered (Vivagraph.js)

I am trying to populate nodes' data in a graph, asynchronously.
How to ensure that data fetched asyncrosly is actually bound to the graph, and rendered when ready?
First, you render the graph structure, node and links.
Second, you render data as nodes' properties, when data is ready.
New node can by dynamically added by interacting on parents' nodes, and don't want to wait for completion of node's properties.
Please note I am using Vivagraph.js library.graph is an object created with the library, addLinks() and getNode() are its function properties - see the demo at Vivagraph demo, I am using that as a draft of my attempts.
The issue I experience is that nodes are rendered in the graph as soon as they are added - addNode() either addLinks(node1, node2) functions -, while node's properties fetched asynchronously - getNode(node).property = updatedValue - result undefined.
EDITED - Simplified code based on comment
Below I include a working mockup version, based on tutorial provided by #Anvaka, the author of this (awesome) library.
My goal is to render the graph immediately, enabling interaction, and update data while it is being fetched from third parties.
// attempt 1: fetch data async
var fetchInfo = function (graph, nodeId) {
var root = 'http://jsonplaceholder.typicode.com';
$.ajax({
url: root + '/photos/' + nodeId,
method: 'GET'
}).then(function (data) {
graph.getNode(nodeId).data = data.thumbnailUrl;
console.log(graph.getNode(nodeId));
});
};
// attempt 2: defer ajax directly
var fetchInfo_2 = function (graph, nodeId) {
var root = 'http://jsonplaceholder.typicode.com';
return $.ajax({
url: root + '/photos/' + nodeId,
method: 'GET'
});
};
function main() {
// As in previous steps, we create a basic structure of a graph:
var graph = Viva.Graph.graph();
graph.addLink(1, 2);
fetchInfo(graph, 1); // updated data is undefined when graph is rendered
fetchInfo(graph, 2); // updated data is undefined when graph is rendered
/* trying a different outcome by deferring whole ajax
graph.getNode(1).data = fetchInfo_2(1).done(function(data) {
data.thumbnailUrl;
}); // the whole object is deferred but cannot fetch data
graph.getNode(2).data = fetchInfo_2(2).done(function(data) {
data.thumbnailUrl;
}); // the whole object is deferred but cannot fetch data
*/
var graphics = Viva.Graph.View.svgGraphics(),
nodeSize = 24,
addRelatedNodes = function (nodeId, isOn) {
for (var i = 0; i < 6; ++i) {
var child = Math.floor((Math.random() * 150) + nodeId);
// I add children and update data from external sources
graph.addLink(nodeId, child);
fetchInfo(graph, child);
}
};
// dynamically add nodes on mouse interaction
graphics.node(function (node) {
var ui = Viva.Graph.svg('image')
.attr('width', nodeSize)
.attr('height', nodeSize)
.link(node.data);
console.log('rendered', node.id, node.data);
$(ui).hover(function () {
// nodes are rendered; nodes' data is undefined
addRelatedNodes(node.id);
});
return ui;

As I said in the comments, any work you want to do as a result of an asynchronous process must be done in the callback. This includes any rendering work.
For jQuery's deferreds (like the result of an Ajax call), the callback is defined through .then or .done, enabling you to detach the act of fetching a resource from working with that resource.
Setting the image source is rendering work, so you must do it in the callback. Below is a function that fetches images and returns the deferred result and the node callback function uses that to do its own piece of work.
function fetchInfo(id) {
var root = 'http://jsonplaceholder.typicode.com';
return $.getJSON(root + '/photos/' + id);
}
function main() {
var graph = Viva.Graph.graph(),
graphics = Viva.Graph.View.svgGraphics(),

addRelatedNodes = function (nodeId, count) {
var childId, i;
for (i = 0; i < count; ++i) {

graph.addLink(nodeId, childId);
}
};

var ui = Viva.Graph.svg('image')
.attr('width', nodeSize)
.attr('height', nodeSize)
.link('http://www.ajaxload.info/images/exemples/24.gif');
$(ui).dblclick(function () {
addRelatedNodes(node.id, 6);
});
// render when ready
fetchInfo(node.id).done(function (data) {
ui.link(data.thumbnailUrl);
});
return ui;
})
.placeNode(function (nodeUI, pos) {
nodeUI.attr('x', pos.x - nodeSize / 2).attr('y', pos.y - nodeSize / 2);

ExtJS : move a record in a grid

I have a simple grid on ExtJS and would like the user to be able to move the record from its original position.
When the user double clicks on a record, a small window containing a combobox appears, he can choose a value on the combobox and then click the save button to apply the change.
However, it doesn't work, I've searched many solutions for this on different forums and none seems to work. Either nothing happens, or an undefined row is added at the end of the grid. Here is the base code I use :
onEditRank: function(view, cell, cellIndex, record, row, rowIndex, e)
{
var reditor = Ext.create('CMS.view.Views.RankEditor', {id: 'reditorView'});
var form = reditor.down('form');
var oldPos = this.getFlatrq().getView().indexOf(record);
var grStore = this.getGridRnkStoreStore();
var i;
var data = [];
for(i = 1; i <= CMS.global.Variables.limit + 1; i++)
{
data.push(i);
}
var combo = Ext.create
(
'Ext.form.field.ComboBox',
{
fieldLabel: 'Rank',
itemId: 'cmbRank',
store: data
}
);
var saveRnk = Ext.create
(
'Ext.button.Button',
{
text: 'Save',
handler: function()
{
}
}
);
form.add(combo);
form.add(saveRnk);
reditor.show();
}
Now here are the different handlers I have tried for my save button :
handler: function()
{
grStore.remove(record);
grStore.insert(record, combo.getValue() - 1);
this.up('form').up('window').close();
}
handler: function()
{
grStore.removeAt(oldPos);
grStore.insert(record, combo.getValue() - 1);
this.up('form').up('window').close();
}
handler: function()
{
var rec = grStore.getAt(oldPos).copy();
grStore.removeAt(oldPos);
grStore.insert(rec, combo.getValue() - 1);
this.up('form').up('window').close();
}
Those 3 handlers inserted undefined rows at the end of my grid. I displayed the values of oldPos and combo.getValue() and they are correct, I also displayed the record variable before and after the remove because I thought it might be destroyed but it wasn't. I have also tried to add a move function to store and call it :
'CMS.store.GridRnkStore',
{
extend: 'Ext.data.Store',
model: 'CMS.model.GridRnkModel',
autoLoad: false,
filterOnLoad: true,
autoSync: true,
move: function(from, to)
{
console.log(from + " " + to);
var r = this.getAt(from);
this.data.removeAt(from);
this.data.insert(to, r);
this.fireEvent("move", this, from, to);
},
}
);
But it didn't work either, it did nothing actually (I put some console.log in the move function to see if it was called and it was, with the right parameters). I'm running out of ideas, any help would be appreciated.
Thank you.
try to set the private move parameter to true of store.remove():
remove: function(records, /* private */ isMove, silent)

Extend polyline and handle mouse event

I write JS app where I draw a lot of polylines using array of points, but in avery point I have some additional properties in this point (GPS data, speed etc).
I want to show these additional props onmouseover or onmouseclick event.
I have two ways:
use the standard polylines and event handler. But in this case I can't to determine additional properties for start point of this polyline cause I can't to save these props in polyline properties. There is one solution - save in array additional properties and try to find them by LatLng of first point of the polyline, but it's too slow I guess..
extend polyline and save additional properties in new Object, but I can't to extend mouse events :(
To extend polyline I use this code:
function myPolyline(prop, opts){
this.prop = prop;
this.Polyline = new google.maps.Polyline(opts);
}
myPolyline.prototype.setMap = function(map) {
return this.Polyline.setMap(map);
}
myPolyline.prototype.getPath = function() {
return this.Polyline.getPath();
}
myPolyline.prototype.addListener= function(prop) {
return this.Polyline.addListener();
}
myPolyline.prototype.getProp= function() {
return this.prop;
}
myPolyline.prototype.setProp= function(prop) {
return this.prop = prop;
}
and create new object in for loop (i - index of current point in array of points) like that:
var polyline_opts = {
path: line_points,
strokeColor: color,
geodesic: true,
strokeOpacity: 0.5,
strokeWeight: 4,
icons: [
{
icon: lineSymbol,
offset: '25px',
repeat: '50px'
}
],
map: map
};
var add_prop = {
id: i,
device_id: device_id
};
...
devices_properties[device_id].tracks[(i-1)] = new myPolyline(add_prop, polyline_opts);
Where:
line_points - array of points (just two points),
i - current point index
devices_properties[device_id].tracks - array of extended polylines (with add properties) by my device_id index
After that I set event handler like that:
var tmp = devices_properties[device_id].tracks[(i-1)];
google.maps.event.addListener(tmp.Polyline, 'click', function(e) {
...
console.log(tmp.prop.id);
...
}
But in this case I always get the same id in console..
When I use
google.maps.event.addListener(devices_properties[device_id].tracks[(i-1)].Polyline, 'click', function(e) {
...
console.log(???); // How to get parent of polyline fired the event?
...
}
I don't know how to get parent of polyline fired the event?
I answer my own question - It's done, I've just have some troubles with using "for" instead "$.each" :)
Before I use:
for ( i = 1; i < devices_properties[device_id].history_points.length; i++ ) {
...
create myPolyline
...
}
and it's doesn't work - created one event handle.
After:
$.each(devices_properties[device_id].history_points, function(i, tmp){
...
create myPolyline ()
...
}
and it works - create a lot of event handlers.
To handle event I use this:
google.maps.event.addListener(c_polyline.Polyline, 'mouseover', function(e) {
var prop = c_polyline.getProp();
...
console.log(prop.id, prop.device_id);
}
