I am trying to create an editable combobox to auto fill from the modelData, which works as intended, the problem I am having is that the sizing of the editable area is really small.
I have used my combobox as a drop down, which the sizing is fine but when I remove the delegate it is much smaller? I have tried altering the size of the editable area but it's still so small; my combobox code is below:
Quick2.ComboBox {
id: combobox2
Layout.preferredWidth: dp(200)
padding: dp(12)
editable: true
model: dataModel.registerCombobox[combobox.currentText]
delegate: Quick2.ItemDelegate {
width: combobox2.width
height: combobox2.height
padding: dp(12)
contentItem: AppText {
text: modelData
color: highlighted ? Theme.tintColor : Theme.textColor
wrapMode: Text.NoWrap
}
highlighted: combobox2.highlightedIndex == index
}
contentItem: AppText {
width: combobox2.width - combobox2.indicator.width - combobox2.spacing
text: combobox2.displayText
wrapMode: Text.NoWrap
}
}
My ItemDelegate and contentItem override the editable section, so removing them allows it to work but it's the sizing I need to cut down? I would also like if possible to remove the ability to create the dropdown popup?
What could be changed to alter the size of the editable area? Below is a screen shot of my 2 comboboxes, one with the content items removed and editable: true and the other a normal use
I have managed to get this working as intended by working with the editableComponent and setting my Layout.preferredHeight as the same as the second combobox shown in the screenshot, code below:
Quick2.ComboBox {
id: combobox
visible: registerCheckbox.checked ? true : false
Layout.preferredWidth: dp(200)
Layout.preferredHeight: combobox2.height
padding: dp(2)
editable: true
EditableComponent {
Quick2.ItemDelegate {
width: combobox.width
height: combobox.height
}
}
model: locations
}

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
}
I need to create components dynamically add added to an area of the screen that, of course, needs to be scrollable. I found out that no matter how many of components I added with the scroll bar as its parent, the scroll bars would not appear and the element would not be scrollable.
I did a little fiddling and I think I came up with a minum working example of what I am talking about:
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")
ScrollView {
width: 200
height: 200
clip: true
Label {
text: "ABC"
font.pixelSize: 224
}
// Rectangle {
// color: "#ff0000"
// width: 100
// height: 100
// }
}
}
This is a modified version of the example used int he official documentation. However when I uncomment the square the screen is no longer scrollable (scroll bars never appear).
If I remove the label and leave the rectangle (making it larger so that there is something to scroll to) it still doesn't work.
I am using Qt 5.10.
So the code below worked for me. I defined a rectangle as a backgroud to get border lines to a scrollable table that I need to create.
Rectangle {
id: tableBackground
color: "#ffffff"
border.width: 2
border.color: "#EDEDEE"
radius: 4
anchors.top: tableHeader.bottom
anchors.left: tableHeader.left
width: vmTableWidth
height: vmTableHeight - tableHeader.height
ScrollView {
id: tableArea
anchors.fill: parent
clip: true
ListView {
id: patientListView
anchors.fill: parent
model: patientList
delegate: VMPatientEntry {
onFetchReport: {
// This is a signal emitted by my VMPatientEntry.
}
}
onCurrentIndexChanged: {
// Do stuff when the current index changes.
}
}
}
}
So I hope this answer allows someone to fix their problem as well.
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
I have one Checkbox with onCheckedChanged handler and what I want is, when the Checkbox is checked, dropdown a menu with several texts and text fields. I have the following code:
CheckBox {
id: box
onCheckedChanged: {
// TODO here to dropdown a menu with settings
}
}
I have texts and text fields like the following:
Component {
id: label
Text {
color: "red"
antialiasing: true
smooth: true
}
}
I'm a newbie in QML so please be patient.
You didn't really say where this menu is located, if it's floating or if it is to just appear maybe displacing other elements on the view. Anyway, to anwser your question, you can achieve what you're asking by setting the height of your 'menu' to zero then, when the CheckBox is checked, setting it to however tall you want it to be. To make the menu grow smoothing you can use a NumberAnimation.
You can change your onCheckedChanged() slot to look like this:
onCheckedChanged: {
menu.height = checked ? 100 : 0
}
and add the following, as a child of your menu element:
Behavior on height { NumberAnimation {...} }
to make the menu's height grow from 0 to 100 over a period of time to make it grow smoothly.
Another approach, which I'd prefer, is to use States with a Transition (instead of a Behavior).
Here is an example of a 'menu' which, when the CheckBox is checked, will slide out from beneath the CheckBox:
import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Window 2.2
ApplicationWindow {
title: qsTr("Hello World")
width: 640
height: 480
visible: true
Rectangle {
id: checkboxContainer
anchors.top: parent.top
anchors.left: parent.left
anchors.right: parent.right
height: 100
color: "pink"
CheckBox {
id: menuCheckBox
anchors.centerIn: parent
text: qsTr("Click Me")
}
}
Rectangle {
id: menu
anchors.top: checkboxContainer.bottom
anchors.left: parent.left
anchors.right: parent.right
height: 0 //This is the default value when the 'default' state is active. That is whenever we're not in the "openState"
clip: true // this hurts rendering performance a bit but is required to make sure child elements don't exceed the bounderies of this object (so when height is zero you don't see the text)
color: "lightblue"
states: [
State {
name: "openState"
when: menuCheckBox.checked // This state is only active when the check box is checked. When you uncheck the check box we move to the 'default' state (which sets the menu's hight back to zero)
PropertyChanges {
target: menu
height: 100
}
}
]
transitions: Transition {
NumberAnimation {
property: "height"
duration: 350 //This means when the height property is changed it will take 350ms to move from what its at to what your changing it to (i.e. 0 to 100 or 100 to 0).
easing.type: Easing.InOutQuad
}
}
Text {
anchors.centerIn: parent
color: "red"
antialiasing: true
smooth: true
text: qsTr("HELLO")
}
}
}
I hope this answers your question.

Row
{
id: horizontalTabs
Loader
{
anchors.fill: parent
sourceComponent: tabsOnBottomComponent
}
}
}
anchors.fill: parent
}
}
This gets shown as follows:
whereas I want it to see 3 rectangles there side by side.
Loader is not a transparent type w.r.t. the containing type, Row in this case. I think this is an issue related to creation context and the way Repeater works. From the documentation of the latter:
Items instantiated by the Repeater are inserted, in order, as children of the Repeater's parent. The insertion starts immediately after the Repeater's position in its parent stacking list. This allows a Repeater to be used inside a layout.
The Rectangles are indeed added to the parent which is the Loader, they stack up - Loader does not provide a positioning policy - then they are added to the Row resulting in just one Item (the last one) to be visible.
You can tackle the problem with few different approaches, depending on the properties you want to maintain or not. I would get rid of anchoring in the Component and move it to the containing Row. A too specific anchoring inside a Component could be a pain in the neck when it is instanced and used all over a (not so small) project.
As a first approach you can re-parent the Repeater to the Row, i.e. you can rewrite code as:
Row
{
id: horizontalTabs
Loader
{
sourceComponent: tabsOnBottomComponent
onLoaded: item.parent = horizontalTabs
}
}
However this would result in warnings due to the Component anchoring references not working as expected any more.
If you still want to maintain the anchoring, as defined in the Component, and off-load the creation, you can go for the dynamic way (if the semantics fits in your use case), i.e. you can use createObject. This way you totally avoid the Loader and the related issue. For instance, you can create the Repeater once the Row has completed its creation:
Row
{
id: horizontalTabs
Component.onCompleted: tabsOnBottomComponent.createObject(horizontalTabs)
}
Clearly, the creation code can be move anywhere else, depending on your needs.
