I'am using Qml to develop a system, I want to change TableViewColumn's default height and its border style. I just want to show the bottom/right borders, to look like table.
In your TableView you could define custom itemDelegate with borders and desired height https://doc.qt.io/qt-5/qml-qtquick-controls-tableview.html#itemDelegate-prop
TableView {
itemDelegate: Rectangle {
height: 30 // put your height here
border.color: "black"
border.width: 1
Text {
anchors.verticalCenter: parent.verticalCenter
color: styleData.textColor
elide: styleData.elideMode
text: styleData.value
}
}
}
You can use rowDelagate property of TableView component.
TableView {
id: idReadDataTableView
anchors.fill: parent
rowDelegate: Rectangle {
width: parent.width
height: 40
}
}

I am using a template to create an app using QT Creator and QML and am hoping to create a landing page that allows users to select which "page" they want to navigate to by clicking an icon.
I've figured out how to get a button on the landing page and have it open another page. However, I am using x and y positions of the button and it doesn't scale correctly when the window size changes.
Ultimately, I am trying to put 6 buttons on the landing page in a way that scales correctly.
I have attached an image of my ideal Landing Page design and have also attached code for what I already have.
I hope I was able to explain this well enough. Please let me know if I can clarify anything.

I think this doc should help you. You haven't really defined what you want very well, but I'll show you some examples so you can hopefully take from it what you need.
QML has the concept of "positioners" and "layouts". Positioners help automatically position your objects neatly on the screen. And Layouts try to do that too, but can also stretch your objects to fill available space.
Row:
You can arrange all your buttons in a row and center the row horizontally.
Row {
anchors.horizontalCenter: parent.horizontalCenter
Button { id: btn1 }
Button { id: btn2 }
...
}
Grid:
Similarly, Grid is a positioner that arranges objects into a grid:
Grid {
anchors.horizontalCenter: parent.horizontalCenter
columns: 3
Button { id: btn1 }
Button { id: btn2 }
...
}
GridLayout:
A GridLayout is just like a Grid, but it can also resize the objects to fill up the space. My opinion is layouts can do more, but they're often trickier to use. In this example, the first button should be a fixed size, while the second button should fill up the remaining width.
GridLayout {
anchors.fill: parent
rows: 2
Button { id: btn1; Layout.preferredWidth: 200 }
Button { id: btn2; Layout.fillWidth: true}
...
}
I'm creating a component in QML, works fine but I want the TEXT field to be in the center of rectangle. For that I've anchored it accordingly but the anchor doesn't work. I don't know why.
Item {
id: root
property int main_rect_height: 32
property int elem_txt_size: 14
property string elem_border_color: "red"
property int elem_width: parent.width/6.5
Rectangle {
id: clients_rect
width: root.parent.width-27
height: main_rect_height
color: "transparent"
border.color: "black"
Rectangle {
id: username_rect
width: elem_width
height: parent.height
color: "transparent"
border.color: elem_border_color
Text {
id: username_txt
text: "USERNAME"
font.pixelSize: elem_txt_size
anchors {
fill: parent
centerIn: parent // THIS DOESN'T WORK!
}
}
}
}
By using anchors.fill: parent, you're setting the size and position of the Text object to match the parent. Centering an object of the same size won't do anything because it already takes up the entire space of the parent. And by default, the text is aligned to the top and left. You have two options:
You can use Text's alignment properties to align the text within itself to be centered:
Text {
anchors.fill: parent
horizontalAlignment: Text.AlignHCenter
verticalAlignment: Text.AlignVCenter
}
Or, you can simply use centerIn without the fill.
Text {
anchors.centerIn: parent
}
I was working with a GridView in QML. When I click on an element, I want to following highlight to happen:
However, my problem is that I want the blue color to appear below the delegate (not in the white area but still visible on the transparent side part) while the checkmark appears above (so it is visible). I have tried playing around with the z values so that the lowest z should be the blue rectangle, the middle should be the white rectangle part of the delegate, and the highest should be the check mark but i can't seem to make it work. Either the highlight or the delegate has to be on top. Does anyone know any way I can fix this so that it works correctly?
Code for highlight:
highlight:
Rectangle {
z:5
color: "steelblue"; radius: 5; opacity: 0.5
Image{
z:8
id: checkMark
visible: found;
x: parent.width-8-width
y: 8
width: 40;
height: 40;
source: "file:///Users/arjun/Documents/CompetitiveBall/images/checkMark.png"
}
}
Code for delegate:
Component {
id: contactsDelegate
Rectangle{
width: grid.cellWidth
height: grid.cellHeight
color: "transparent"
Rectangle {
z:7
width: grid.cellWidth-20
height: grid.cellHeight-20
id: wrapper
anchors.horizontalCenter: parent.horizontalCenter
anchors.verticalCenter: parent.verticalCenter
border.width: 3
border.color: "black"
radius: 5;
Image{
id: mImage
x:parent.x
width: 65
height:65;
source: picSource
}
Text{
width: grid.cellWidth-15
y: mImage.y+mImage.height+4
anchors.horizontalCenter: parent.horizontalCenter
id: nameText
text: name
font.family: "Palatino Linotype"
font.bold: (grid.isCurrentItem===true)?"true":"false"
horizontalAlignment: Text.AlignHCenter
color:"#050027"
}
MouseArea{
anchors.fill: parent
onClicked:{
console.log("Clicked on :" + name)
//what happens when u click
grid.currentIndex=index;
}
}
}
}
}
Since you want part of the highlight to be underneath the delegate and part of it to be on top, you need to break it up into different pieces. I tested the code below with Qt 5.15.0. I made the normal highlight object draw underneath the delegate. Then I added another Rectangle that follows the highlight that draws on top of the delegate.
GridView
{
id: lv
anchors.fill: parent
anchors.margins: 50
cellWidth: 50
cellHeight: 50
model: 30
// By default, highlight draws behind delegates
// (You can specify a positive z-value to make it draw on top)
highlight: Item
{
Rectangle
{
anchors.centerIn: parent
width: 50
height: 50
color: "green"
}
}
delegate: Rectangle
{
width: 30
height: 30
color: "red"
MouseArea
{
anchors.fill: parent
onClicked: lv.currentIndex = index;
}
}
// This will draw on top of the delegates
// (You can change that by specifying a negative z-value.)
Rectangle
{
id: checkbox
x: lv.highlightItem.x - lv.contentX
y: lv.highlightItem.y - lv.contentY
width: 10
height: 10
color: "blue"
}
}
Trying different code combinations and partially solving my problem I came across a behavior that I can not quite explain. So to the point, When I create a simple TextArea without Scrollview it looks like this:
RowLayout {
id: rowLayout
Rectangle{
height: 50
width: 295
TextArea {
id: textArea
text: (" message...")
wrapMode: Text.WrapAnywhere
anchors.fill: parent
}
}
Text area creates a default background. And now I want to do TextArea with ScrollView ALSO with the default TextArea background but it comes out something like that :
RowLayout {
id: rowLayout
Rectangle{
height: 50
width: 295
ScrollView {
id: scrollView1
anchors.fill: parent
TextArea {
id: textArea
text: (" message...")
wrapMode: Text.WrapAnywhere
}
}
}
The only chance to set the default TextArea background is set implicitHeight,implicitWidth but then after entering the text into a TextArea until the scrollbar appears, the background extends over the entire length by going behind the other components like this :
RowLayout {
id: rowLayout
Rectangle{
//color: "#00000000"
height: 50
width: 295
ScrollView {
id: scrollView1
anchors.fill: parent
TextArea {
id: textArea
text: (" message...")
wrapMode: Text.WrapAnywhere
implicitHeight: 50
implicitWidth: 295
}
}
}
So the only thing I want is a scrollable textarea but with this black default background and NOT my background which I can do with rectangle.
Can anyone take a look?
Thank you :)
I tried do my best. Check the example below, hope it will help =)
import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3
ApplicationWindow {
visible: true
width: 400
height: 400
RowLayout {
width: 295
height: 50
anchors.centerIn: parent
ScrollView {
Layout.fillHeight: true
Layout.fillWidth: true
background: Rectangle { color: "black" }
TextArea {
id: messageField
placeholderText: qsTr("message...")
color: "white"
wrapMode: TextArea.WrapAnywhere
}
}
}
}
Result:
We are developing an application on IMX6 using Qt 5.3.2. The Qt libraries are provided by Yocto.
Our requirement is to list items inside a drop down menu using a particular background style. For this purpose we are using ComboBox provided by Qt Quick Controls and QtQuick.Controls.Styles for customizing the drop down background style. We are using MenuStyle component to customize the drop down.
When we apply the styles, we observed that the drop down bottom border does not close.
Please use the following link to view the picture.
We are not facing this issue in the Desktop. We tried running the same application on Ubuntu 12.04.

Also, below I've listed the qml code which we used for Customizing the drop down.
ComboBox {
id: comboFilterBy
x: 10
y: 130
z:1
width: 285
height: 39
model : eventFiltersList
Rectangle {

// anchors.fill: parent
width: 10
height: arrow.height
anchors.centerIn: parent
clip: true
smooth: true
fillMode: Image.PreserveAspectFit
source: "images/dropDownArrow.png"
}
}
style: ComboBoxStyle {
background:
Rectangle {

}
label: Text {

horizontalAlignment: Text.left
font.pointSize: 19
font.family: "WenQuanYi Micro Hei Mono"
color: "black"
text: control.currentText
}
// drop-down customization here
property Component __dropDownStyle: MenuStyle {
__maxPopupHeight: 240
__menuItemType: "comboboxitem"
padding.bottom : getPaddingLength(1)
frame: Rectangle { // background
color: "#fff"
border.width: 1
}
itemDelegate.label: // an item text
Text {
verticalAlignment: Text.AlignVCenter
horizontalAlignment: Text.AlignHCenter
font.pointSize: 19
font.family: "WenQuanYi Micro Hei Mono"
color: "black"
text: styleData.text
}
itemDelegate.background: Rectangle { // selection of an item
color: styleData.selected ? "#5692c4" : "transparent"
}
__scrollerStyle: ScrollViewStyle { }
}
}
Any help is greatly appreciated.
