I have a file named page2.qml like below
Page {
id: page
Rectangle {
id: container
anchors.fill: parent
width: parent.width * 0.8
Rectangle {
id: title
anchors.top: parent.top
width: parent.width
height: 50
color: "salmon"
}
ListView {
id: listView
currentIndex: -1
anchors.top: title.bottom
anchors.bottom: parent.bottom
delegate: Rectangle {
height: 20
width: 100
border.color: "red"
color: "pink"
Text {
text: model.index
}
}
model: 100
}
}
}
the result is in this image:
Since the listview contain 100 item, how can i make the whole page scrollable? i can make just listview scrollable but not the whole page.
If you don't need the ListView to be scrollable by itself but your whole container need to, you could use a Repeater instead and put it inside a Column wrapped in a Flickable :
Flickable {
id: container
contentHeight: column.implicitHeight
contentWidth: width
width: parent.width * 0.8
height: parent.height
Column {
id: column
width: parent.width
Rectangle {
id: title
width: parent.width
height: 50
color: "salmon"
}
Repeater {
id: listView
model: 100
delegate: Rectangle {
height: 20
width: 100
border.color: "red"
color: "pink"
Text {
text: model.index
}
}
}
}
}

I have ListView with items like this:
And I want use swipe. But when I add SwipeDelegate I get this:
How I can make swipe elements over the text? I try use z properties, but with z my swipe not animated when opened and I can't close it.
Here my code:
//SomePage.qml:
import QtQuick 2.12
import QtQuick.Controls 2.12
ScrollView {
ListView {
id: someListView
model: SomeItems {}
delegate: SwipeDelegate {
width: someListView.width
Row {
leftPadding: 5
width: parent.width
Image {
id: someImg
height: 38
source: myImage
width: height
}
Column {
leftPadding: 5
width: parent.width - someImg.width - 10
// Name
Text {
id: someName
text: myCount.toString() + " × " + myName
}
// Number
Text {
id: someNumber
text: myNumber.toLocaleString(Qt.locale("ru-RU"), "f", 0)
anchors.right: parent.right
font.pixelSize: 12
rightPadding: 5
}
}
}
swipe.right: Row {
anchors.right: parent.right
height: parent.height
// Delete button
Label {
text: "\ue800"
color: "black"
font.family: fontFontello.name
height: parent.height
padding: 12
verticalAlignment: Label.AlignVCenter
width: this.height
background: Rectangle {
color: "lightblue"
height: parent.height
width: parent.width
MouseArea {
anchors.fill: parent
onClicked: someListView.model.remove(index)
}
}
}
// Hide button
Label {
text: "\ue80a"
color: "black"
font.family: fontFontello.name
height: parent.height
padding: 12
verticalAlignment: Label.AlignVCenter
width: this.height
background: Rectangle {
color: "lightgray"
MouseArea {
anchors.fill: parent
onClicked: {
...
swipe.close()
}
}
}
}
}
}
}
}
The problem is you're adding your text/image on top of the default contentItem instead of inside it. It will look correct if you add your Row to contentItem, like this:
delegate: SwipeDelegate {
contentItem: Row {
...
}
}
I have a ListView where the items become visible or not based on whether a header was expanded or not. When the visible property is set to false, there is just blank space in that area. How do I remove the black space in the list so that the next visible item comes in view?
Currently I have set the height:model.count * 50 with 50 being height of each item. I tried subtracting 50 every time an item's visible property is set to false but this just reduces the height of the list overall but the blank space remains.
ListView { id: list
focus: true
anchors.top: header.bottom
anchors.left: parent.left
anchors.right: parent.right
width: parent.width
height:model.count*50
model:hall
Component {
id:comp
Item{
width: parent ? parent.width : 0
height: parent ? parent.height: 0
Column{
id:col1
width: parent.width - 16
height: 25
anchors.centerIn: parent
spacing: 3
Text { id: name
width: parent.width
text: name
elide: Text.ElideMiddle
font: "black"
color: "grey"
}
Row{
width: parent.width
Text { id: file1
width: parent.width * 0.6 - 5
text: "hello"
horizontalAlignment: Text.AlignLeft
elide: Text.ElideMiddle
font: systemFont.TableCellFont
}
Text { id: file2
width: parent.width*0.4 - 3
horizontalAlignment: Text.AlignRight
text: mod
font: systemFont.TableCellFont
}
}
}
MouseArea {
anchors.fill: parent
onClicked: {
console.warn("Mouse onClicked")
}
}
}
}
delegate: Item {
width: parent.width;
height: {
if (!cric && expanded)
return 50
else
return 0
}
Loader {
anchors.fill: parent
sourceComponent: comp
height: expanded? 50: 0
readonly property int index:model.index
readonly property string mod: model.mod
visible: !cric && expanded
}
}
Keys.onReturnPressed: {
console.warn("Return pressed")
}
}
The blank space is created because the List item which is hidden by setting visible to false still has its dimensions set. You can update the item height to 0 and the blank space will not be visible. Try this example for reference.
import QtQuick 1.1
Rectangle{
width: 400; height: 400
color: 'lightblue'
ListView{
width: 400; height: count * 30
model: 20
delegate: Rectangle{
id: rectDel
width: 200; height: 30
color: 'lightgreen'
border{
width: 1
color: 'black'
}
Text{
text: index
anchors.centerIn: parent
}
Rectangle{
width: 20; height: 20
radius: 10
color: 'red'
anchors{
verticalCenter: parent.verticalCenter
right: parent.right; rightMargin: 10
}
Text{ text: 'X'; anchors.centerIn: parent; }
MouseArea{
anchors.fill: parent
onClicked: {
rectDel.visible = false
rectDel.height = 0
}
}
}
}
}
}
I am trying to drag and drop a ListView row and I am having trouble at the drag stage. Below code doesn't drag anything and name column is not aligned properly. I don't want to specify a size for ListView and I want it to get its size from its content Row with id row. It should be able to because text has size coming from its font size and Rectangle has set width. ListView can get wider as needed to show the name part.
import QtQuick 2.11
import QtQuick.Layouts 1.11
ListView {
id: root
height: scrollview.viewport.height
model: listModel
delegate: dragDelegate
Component {
id: dragDelegate
MouseArea {
id: dragArea
anchors { left: parent.left; right: parent.right }
height: content.height
drag.target: pressed ? content : undefined
drag.axis: Drag.XAndYAxis
Rectangle {
id: content
anchors {
horizontalCenter: parent.horizontalCenter
verticalCenter: parent.verticalCenter
}
height: row.implicitHeight
border.width: 1
border.color: "lightsteelblue"
color: "green"
radius: 2
states: State {
when: dragArea.pressed
ParentChange { target: content; parent: root }
AnchorChanges {
target: content
anchors { horizontalCenter: undefined; verticalCenter: undefined }
}
}
Row {
id: row
Text {
text: name
font.pointSize: 15
}
Rectangle {
height: parent.height
width: 40
color: hexColor
}
}
}
}
}
ListModel {
id: listModel
ListElement {
name: "first-name"
hexColor: "red"
}
ListElement {
name: "second-name"
hexColor: "green"
}
}
}
I'm developing a BlackBerry 10 mobile application using the Momentics IDE 2.1.2 (native SDK).
I'm looking for a sample that shows how to build a horizontal pagination like in the image below that I will put it inside a container replacing with that a listview with a grid display.
Can anyone help me with this ?
You can easy build simple pagination using ListView only. Hope the example below will be usefull:
import QtQuick 2.4
Item {
width: 600
height: 800
ListView {
id: listView
anchors.fill: parent
orientation: ListView.Horizontal
snapMode: ListView.SnapToItem
highlightRangeMode: ListView.StrictlyEnforceRange
model: 5
clip: true
delegate: Rectangle {
width: listView.width
height: listView.height
color: Qt.rgba(Math.random(),Math.random(),Math.random(),1);
Text {
anchors.centerIn: parent
text: "page " + index
}
}
}
Item {
anchors.bottom: parent.bottom
anchors.left: parent.left
anchors.right: parent.right
height: 30
Row {
anchors.centerIn: parent
Repeater {
model: listView.model
Rectangle {
width: 20
height: 20
border.width:2
border.color: "white"
color: index == listView.currentIndex ? "orange" : "white"
Text {
anchors.centerIn: parent
text: index
}
}
}
}
}
}
I have a nested ScrollView, similar to the following QML:
import QtQuick 2.0
import QtQuick.Controls 1.1
Rectangle {
width: 200
height: 600
ScrollView {
id: sView
anchors.fill: parent
ListView {
id: list
boundsBehavior: Flickable.StopAtBounds
clip: true
focus: true
interactive: true
model: 5
delegate: Component {
MouseArea {
id: hoverArea
width: 100
height: 200
onClicked: list.currentIndex = index;
Rectangle {
id: fauxParent
anchors.fill: parent
border.width: 1
border.color: "black"
Rectangle {
anchors.top: parent.top
anchors.left: parent.left
height: parent.height
width: parent.width / 2
border.width: 1
border.color: "purple"
color: "green"
Text {
anchors.centerIn: parent
text: "stuff"
}
}
ScrollView {
//parent: sView
anchors.top: fauxParent.top
anchors.right: fauxParent.right
height: fauxParent.height
width: fauxParent.width / 2
ListView {
model: 3
delegate: Component {
Rectangle {
radius: 10
height: 100
width: 100
color: "blue"
}
}
}
}
}
}
}
}
}
}
It seems to run correctly, except that the inner ScrollView won't respond to the mousewheel: the outer ScrollView intercepts that event. The only fix I've found in research for this, is to set the inner scrollview's parent directly to the outer scrollview (uncomment the parent: sView line). Unfortunately, this re-positions all five scrollview delegates onto the top right corner of the outer scrollview. It seems that ScrollView positions itself based on its parent?
For the record, my actual application is wrapping a large section of the page in a scrollview so as to allow the user to access sections of it that may be out of bounds for the current window size. The content of this section, though, has a variety of different controls for a variety of different purposes, including some scrollviews. So I'd also accept an alternate way of moving around a set of generic content that's too large for the window.
This is a Windows desktop app, so I don't need to consider mobile-specific issues.
You nested four elements that handle scroll Events.
Why do you put a ScrollView arround a ListView?
If you remove the ScrollViews the Mousewheel work fine.
Rectangle {
width: 200
height: 600
ListView {
anchors.fill: parent
id: list
boundsBehavior: Flickable.StopAtBounds
clip: true
focus: true
interactive: true
model: 5
delegate: Component {
MouseArea {
id: hoverArea
width: 100
height: 200
onClicked: list.currentIndex = index;
Rectangle {
id: fauxParent
anchors.fill: parent
border.width: 1
border.color: "black"
Rectangle {
anchors.top: parent.top
anchors.left: parent.left
height: parent.height
width: parent.width / 2
border.width: 1
border.color: "purple"
color: "green"
Text {
anchors.centerIn: parent
text: "stuff"
}
}
ListView {
anchors.top: fauxParent.top
anchors.right: fauxParent.right
height: fauxParent.height
width: fauxParent.width / 2
model: 3
delegate: Component {
Rectangle {
radius: 10
height: 100
width: 100
color: "blue"
}
}
}
}
}
}
}
}
