I want to make my QML Grid scrollable as soon as the content is too long for it to display.
Grid {
objectName: "sidebarView"
id: sidebarGrid
flow: Grid.TopToBottom
columns: 1
spacing: 10
}
Is that possible with just a few properties added to the Grid?
No, but you can just put a Flickable around the Grid
Flickable {
anchors.fill: parent
contentHeight: sidebarGrid.height
contentWidth: sidebarGrid.width
Grid {
objectName: "sidebarView"
id: sidebarGrid
flow: Grid.TopToBottom
columns: 1
spacing: 10
}
}

I have made a delegate for listview that contains Combobox. If I open the Combobox and scroll the listview, the Combobox popup is moving with the delegate position, that's ok. But when the delegate goes out of the listview area(Ref the sample image attached), Combobox popup continues to moves even out of the listview area.
How to close the Combobox when the corresponding delegate goes out of the listview area.
Thanks in advance...
Code goes here
import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Controls 2.2
Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
Column {
spacing: 0
anchors.fill: parent
Item {
width: parent.width
height: parent.height * 0.4
Image {
anchors.fill: parent
anchors.margins: 10

}
}
ListView {
width: parent.width
height: parent.height * 0.7
model: 10
spacing: 5
clip: true
delegate: Rectangle {
width: parent.width
height: 50
color: index % 2 == 0 ? "lightsteelblue" : "steelblue"
Row {
spacing: 25
anchors.centerIn: parent
Label {
text: qsTr("%1").arg(index)
anchors.verticalCenter: parent.verticalCenter
}
ComboBox {
anchors.verticalCenter: parent.verticalCenter
model: ["a", "b", "c"]
}
}
}
}
}
}
If there is no particular goal to keep ComboBox popup opened when scrolling, then add the following property to your ListView:
highlightRangeMode: ListView.StrictlyEnforceRange
This will close ComboBox popup when ListView is being scrolled.
P.S.
Also, resolves your issue with the ComboBox list getting out of view area.
UPDATE on issue with header element hiding below other list items:
Accordingly to the description ListView.StrictlyEnforceRange - the highlight never moves outside of the range. The current item changes if a keyboard or mouse action would cause the highlight to move outside of the range. when an item goes out of range the list changes next item and that makes ComboBox closing its popup, but since header item is below the other ListView items itself (see this paragraph https://doc.qt.io/qt-5/qml-qtquick-listview.html#stacking-order-in-listview , delegate is always above a header) it makes impossible displaying default header here at the top of the other items. I'd suggest you implement your own header beyond the list. Sorry, I might not have known Qt so good to find the other solution.
I have a QML page that with a GridLayout that contains the page title, ListView and close button:
GridLayout {
columns: 1
rows: 5
anchors.fill: parent
<page title item>....
ListView
{
spacing: 15
model: logModel
delegate: Item {
implicitWidth: parent.width
implicitHeight: grid.height
RowLayout
{
id: grid
spacing: 0
width: parent.width
height: commentLabel.implicitHeight
<icon>....
Label {
id: commentLabel
Layout.fillWidth: true
text: comment
wrapMode: Label.Wrap
}
}
}
ScrollIndicator.vertical: ScrollIndicator { }
}
<close button>...
}
When I scroll the list, the first and the last visible item in the list may go beyond the list bounder and intersect the page title or close button:
How to prevent this and make the items clipped?
EDIT1:
I tried to add
clip: true
to ListView, delegate Item, RowLayout and Label, but with no success. According to docs, ListView with clip property set to true should clip its content, should not it?
I found a similar question where clip property is the answer, but it is not clear why it does not work with my ListView.
My QT version is 5.13.2.
Set clip:true in the ListView component.
ListView
{
clip:true
}
For a project I am showing data in a table, the newest data is the most relevant so I want that to be the most visible but it should also be possible to see the earlier data.
The following code contains the view with a scrollbar.
ScrollView{
id:dataScrollView
width: parent.width
anchors.top: headerWrapper.bottom
height:parent.height - headerWrapper.height
ScrollBar.vertical.policy: ScrollBar.AlwaysOn;
clip: true
TableView{
id: table
columnSpacing: 1
rowSpacing: 1
clip: true
implicitHeight: column.height - 33
implicitWidth: column.width
model: modelItem
delegate: compColored
onContentHeightChanged: {
//new data has come in I want to scroll to the bottom
console.log("update scroll to bottom" )
}
}
}
I know exactly where to put the code but i do not know how I can make the scrollbar go to the bottom or how to set the position of the scrollbar.
Can someone point me out to how I can set the position of the scrollbar?
As TableView inherits Flickable, you can reposition the contentItem within the viewport simply by:
onContentHeightChanged: {
table.contentY = table.contentHeight - table.height
}
and the Flickable's contentItem bottom area will be visible in the viewport.
I have a list view. If i click on a cell, that specific cell need to move to the center with a small scrolling animation. With my code, the clicked cell will comes to the center without any animation.
Is it possible to add animation for that ?
Am putting my code below :
ListView {
id: source_list
width: 1080
height: 480
spacing: 50
model: mediaSongsModel
delegate: mediaSongsDelegate
focus: true
interactive: true
clip: true
highlightMoveDuration: 50
snapMode: ListView.SnapToItem
boundsBehavior:Flickable.StopAtBounds
preferredHighlightBegin: 260/scaleFactor
preferredHighlightEnd: 260/scaleFactor
highlightRangeMode: ListView.StrictlyEnforceRange
}
Component {
id: mediaSongsDelegate
Item {
id: wrapper
width: 1080
height: 200
MouseArea {
anchors.fill: parent
onClicked: {
source_list.currentIndex = index
source_list.positionViewAtIndex(index,ListView.Center)
}
}
}
}
If the current item should always be in the center or within a specific are of the view, then you can use the preferredHighlightBegin and preferredHightlightEnd properties to define that area.
The value of highlightRangeMode controls if and if yes, how strictly this applies. E.g. if the first item is the current item and the value is StriclyEnforeRange then the item will be within the specified area even if that means scrolling further up than a normal "scroll to top" would.
Something like that should work
ListView {
preferredHighlightBegin: height / 2 - 100 // 100 being item height / 2
preferredHighlightEnd: height / 2 + 100 // 100 being item height / 2
highlightRangeMode: ListView.StrictlyEnforceRange
}
I've solved my issue by removing the following line of code:
source_list.positionViewAtIndex(index,ListView.Center);
The animation correctly worked.
I'd like to create my own styled RadioButton, but I'm having difficulty controlling the size of the components used in the RadioButtonStyle that I am using. I want to put my RadioButton in a GridLayout and have the RadioButton take up all the available space (as if I were setting Layout.fillWidth and Layout.fillHeight to true)
To start off with, I am using the RadioButtonStyle code from the Qt docs inside a GridLayout:
GridLayout {
columns: 3
anchors.fill: parent
RadioButton {
text: "Radio Button"
style: RadioButtonStyle {
indicator: Rectangle {
implicitWidth: 16
implicitHeight: 16
Rectangle {
anchors.fill: parent
visible: control.checked
color: "#555"
}
}
}
}
}
we can see that implicitWidth and implicitHeight of the indicator Rectangle are set int literals. I want to size the indicator Rectangle to fill the space provided by the layout.
I would like the width and height of the indicator Rectangle to track the width and height of the RadioButton, which in turn tracks the width and height of the GridLayout cell containing it.
== UPDATE ==
I have tried the following - setting Layout.maximumHeight/Width prevents Qml going into some kind of infinite loop
RadioButton {
id: rdbt
Layout.fillHeight: true
Layout.fillWidth: true
Layout.maximumWidth: 200
Layout.maximumHeight: 200
style: RadioButtonStyle {
id: ab
indicator: Rectangle {
color: "blue"
height: control.height
width: control.width //control.width
