Remove "British-English" in Virtual Keyboard QML - qt

How to remove "British-English" which is in the spacebar? Please refer below image.
[Update 1]:
Following is the code that i am using for input panel:
InputPanel {
id: inputPanel
parent:mainWindow.contentItem
z: 1000002
anchors.bottom:parent.bottom
anchors.left: parent.left
anchors.right: parent.right
visible: Qt.inputMethod.visible
}

You'd need to make a custom style where you override the spaceKeyPanel. For example, adapting the default style's spaceKeyPanel:
spaceKeyPanel: KeyPanel {
Rectangle {
id: spaceKeyBackground
radius: 5
color: "#35322f"
anchors.fill: parent
anchors.margins: keyBackgroundMargin
}
}

What correct architecture of qml dynamic widgets?

Its very hard to formulate question. But look on the followind picture:
For example there are exists list widget which items dynammically change content when receive hover state. For simplicity item contents depends on some set of bool values.
With QWidgets its easy could be achieved by checking the bool values when some signal raised and show/hide dependent components.
But how it could achieved with qml?
As I understand correctly the qml gui - its kind of "static" GUI and I should have different gui set to switch. But in described example I receive the combinatorial explosion.
I am not sure I got your question right, but let's begin from examples
ListModel {
id: listModel
ListElement {
name: "John"
age: 32
gender: "male"
}
ListElement {
name: "Kate"
age: 23
gender: "female"
}
}
ListView {
anchors.fill: parent
model: listModel
spacing: 5
delegate: Rectangle {
color: "#24F5F2"
width: parent.width
height: 50
Text {
id: nameText
anchors.top: parent.top
anchors.left: parent.left
anchors.right: parent.right
text: name
}
Text {
id: ageOrGenderText
anchors.bottom: parent.bottom
anchors.left: parent.left
anchors.right: parent.right
text: gender
}
MouseArea {
anchors.fill: parent
hoverEnabled: true
onEntered: {
ageOrGenderText.text = age
}
onExited: {
ageOrGenderText.text = gender
}
}
}
}
Also, you can create a separate boolean property and set it on entered/exited to true/false and do a QML binding to this property
property bool hovered: false
Text {
id: textItem
anchors.bottom: parent.bottom
anchors.left: parent.left
anchors.right: parent.right
text: hovered ? "age" : "gender" // or CppBackend.GetValue(hovered)
}
MouseArea {
anchors.fill: parent
hoverEnabled: true
onEntered: {
textItem = true;
}
onExited: {
textItem = false;
}
}

Qtvirtualkeyboard not showing in application

Here is my problem, I have want to use the qt virtual keyboard. I have it working on the desktop but on my raspberrypi3 (running minimal root filesystem) it does not pop up.
I have put
qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));
in main.cpp
and have put the InputPanel in main.qml
import QtQuick 2
import QtQuick.VirtualKeyboard 2.1
Item {
id: root
Item {
id: appContainer
anchors.left: parent.left
anchors.top: parent.top
anchors.right: parent.right
anchors.bottom: inputPanel.top
//...
}
InputPanel {
id: inputPanel;
y: parent.height; // position the top of the keyboard to the bottom of the screen/display
anchors.left: parent.left;
anchors.right: parent.right;
Component.onCompleted: {
inputPanel.keyboard.style.languagePopupListEnabled = false;
}
states: State {
name: "visible";
when: inputPanel.active;
PropertyChanges {
target: inputPanel;
// position the top of the keyboard to the bottom of the text input field
y: parent.height - inputPanel.height;
}
}
}
}
When I try to use it on the rp3 it does not appear. Any ideas?

QML Virtual keyboard Hide button not working

I am having a problem if I click on keyboard hide button .Following is the code :
import QtQuick 2.6
import QtQuick.Window 2.2
import QtQuick.Controls 2.2
import QtQuick.VirtualKeyboard 2.2
Window {
visible: true
width: 600
height: 500
title: qsTr("Hello World")
TextField {
id: textfield
anchors.bottom:(inputPanel.visible) ? inputPanel.top : parent.bottom
color: "#2B2C2E"
cursorVisible: activeFocus
selectionColor: Qt.rgba(0.0, 0.0, 0.0, 0.15)
selectedTextColor: color
}
InputPanel {
id: inputPanel
z: 89
anchors.bottom:parent.bottom
anchors.left: parent.left
anchors.right: parent.right
visible: Qt.inputMethod.visible //** Warning here
}
}
Below are the use-cases:
If i click on TextField keyboard pops as expected but when I click on hide keyboard button it's not hiding.
If i click on TextField keyboard pops as expected, next if I double-click on TextField and then click on hide keyboard button it's hiding.
I am also getting a warning as :
QML InputPanel: Binding loop detected for property "visible"
Please suggest.
The basic example shows the input panel when its active property is true:
InputPanel {
id: inputPanel
z: 89
y: appContainer.height
anchors.left: parent.left
anchors.right: parent.right
states: State {
name: "visible"
/* The visibility of the InputPanel can be bound to the Qt.inputMethod.visible property,
but then the handwriting input panel and the keyboard input panel can be visible
at the same time. Here the visibility is bound to InputPanel.active property instead,
which allows the handwriting panel to control the visibility when necessary.
*/
when: inputPanel.active
PropertyChanges {
target: inputPanel
y: appContainer.height - inputPanel.height
}
}
transitions: Transition {
id: inputPanelTransition
from: ""
to: "visible"
reversible: true
enabled: !VirtualKeyboardSettings.fullScreenMode
ParallelAnimation {
NumberAnimation {
properties: "y"
duration: 250
easing.type: Easing.InOutQuad
}
}
}
Binding {
target: InputContext
property: "animating"
value: inputPanelTransition.running
}
}
So you could do something similar:
InputPanel {
id: inputPanel
z: 89
anchors.bottom:parent.bottom
anchors.left: parent.left
anchors.right: parent.right
visible: active
}
I don't know what was the issue but when I added the TextField inside TextInput everything started to work,Below is the code :
TextInput {
width:300
height:50
id: textfield
anchors.bottom:(inputPanel.visible) ? inputPanel.top : parent.bottom
color: "#2B2C2E"
TextField{
width:parent.width
height:parent.height
}

Signals between pages

I am trying to communicate between 2 QML pages.
In my page Main.qml I receive a signal from my C++ code. On receiving this signal I want text on InputPage.qml to change. This page is shown within Main.qml using a Loader. The only way I could find so far is to set up another signal between the 2 pages. However, I think there is a much easier way to do this. I already tried this way but I could not get it to work. So before I proceed I would like to know if this is the right method or not.
Any ideas on how to do this, and if the method described above is the correct one?
My code:
Main.qml
Item {
id: screen_InputPage
width: 1920
height: 930
anchors.left: parent.left
anchors.leftMargin: 0
anchors.top: parent.top
anchors.topMargin: 100
visible: false
opacity: 1
Loader {//Loads the pages
id: pageLoader_ID2
source: "inputPage.qml"
}
}
And i would like to access the text(and maybe functions) placed on inputPage.qml
Text {
id: text_volume_perc_ID1
height: 48
text: qsTr("50")
anchors.right: parent.right
anchors.rightMargin: 0
verticalAlignment: Text.AlignVCenter
horizontalAlignment: Text.AlignHCenter
anchors.top: parent.top
anchors.topMargin: 126
anchors.left: parent.left
anchors.leftMargin: 0
font.pixelSize: 42
}
To access the created object, you can use
idLoader.item.idInputpage.idText.text
I propose that you load objects dynamically to improve performance. To do so you can create your own CustomLoader.qml:
CustomLoader.qml
import QtQuick 2.0
Item {
id: idRoot
width: childrenRect.width
height: childrenRect.height
property Item createdObject
property string source
function fnSourceChange() {
if (""!== source){
var component
// create component
component = Qt.createComponent(source)
if (Component.Ready === component.status) {
createdObject= component.createObject(idRoot)
if(!createdObject)
console.log("Loader::Could not create the object ")
}
else {
console.log("Loader::Could not create panel", component.errorString(), "component has errors")
}
}
else {
createdObject.destroy();
createdObject = null
// unComment this line if you want to force the garbage collector
//gc()
}
}
onSourceChanged: {
fnSourceChange()
}
// even without that it should detect the source change and create it
// you can unComment this line if you want, but like that it will parse the function
// two times one on the sourceChanged signal and on on in this handler
// print the source or somthing in the function and you'll see
// Component.onCompleted: fnSourceChange()
}
main.qml
import QtQuick 2.0
Item {
id: screen_InputPage
width: 1920
height: 930
anchors.left: parent.left
anchors.leftMargin: 0
anchors.top: parent.top
anchors.topMargin: 100
visible: false
opacity: 1
CustomLoader{
id: pageLoader_ID2
source: "inputPage.qml"
}
}
InputPage.qml
import QtQuick 2.0
Item {
width: 800
height: 480
property alias text: idText.text
property alias label: idText
property alias rect: idRect
Text{
id: idText
}
Rectangle{
id: idRect
width: 100
height: 200
}
}
In your main add :
//or another scope like click button
Component.onCompleted: {
pageLoader_ID2.createdObject.text = "hello"
pageLoader_ID2.createdObject.rect.color = "red"
}

how to load a new screen in QML showing a new list based on previous user click input?

In my application i show a nested list, that shows groups and folders as its children. I have built the functions necesary to generate a new list in the backend in c++ based on which item is clicked by the user.
I allready have the necesary functionality to pass the list to qml through QProperty.
so my question is, how do i previous listviews and show new ones dynamically. Considering it should also be possible to click the button "back", which should load the previous page again showing the groups and the folders.
this is the code i have now, showing the groups and its children(folders)
import QtQuick 2.4
import QtQuick.Window 2.2
//import ListMode 1.0
Rectangle {
height: 250
width: 140
color: "pink"
//property var aNum: 0
Component {
id: folderDelegate
Item {
width: 140
height: col2.childrenRect.height
Column {
id: col2
anchors.left: parent.left
anchors.right: parent.right
Rectangle {
height: 20
width: parent.width
border.color: "black"
MouseArea {
anchors.fill: parent
onClicked: treemodel.getObject(model.ID + ":" + model.Name)
}
Text {
anchors.horizontalCenter: parent.horizontalCenter
anchors.verticalCenter: parent.verticalCenter
id: name1
text: model.Name
}
}
}
}
}
ListView {
id: outer
model: myModel
delegate: groupsDelegate
anchors.fill: parent
}
Component {
id: groupsDelegate
Item {
width: 140
height: col.childrenRect.height
Column {
id: col
anchors.left: parent.left
anchors.right: parent.right
Text {
anchors.horizontalCenter: parent.horizontalCenter
id: t1
font.bold: true
font.underline: true
font.pointSize: 9
text: model.Name
}
ListView {
id: folderlist
model: treemodel.lists[treemodel.modIndex]
delegate: folderDelegate
contentHeight: contentItem.childrenRect.height
height: childrenRect.height
anchors.left: parent.left
anchors.right: parent.right
clip: true
}
}
}
}
}
i have been reading documentations and searching forums, but the information is pretty overwhelming. So a pointer in the right direction would be appreciated.
the main model is setup for each item to have its own unique ID. So when an item is clicked, i run a function that grabs and stores the item based on the ID + name that was clicked
MouseArea {
anchors.fill: parent
onClicked :{
treemodel.getObject(model.ID + ":" + model.Name)
stackView.push(Qt.resolvedUrl("content/ButtonPage.qml"))
}
}
next, based on the item that was clicked i have functions that fill different QList items which are loaded into the ButtonPage.qml.
the function in c++ that is invoked is:
Q_INVOKABLE void getObject(QString index) {
clickedItemID = index;
getClickedItem();
getFilesByFolder();
}
now, i am not sure if this is a good solution. But for me it works. Maybe it will work for someone else too.
