How to create a message dialog using QML Control elements(such as combobox, textfield, checkbox..)
I still can't understand what are you going to do. Assume, you want some custom dialog with varying content. First of all, I guess MessageDialog
is not good idea just because you cannot define custom controls inside it. But you can create a custom one.
Simple example:
Popup.qml
import QtQuick 2.2
import QtQuick.Controls 1.2
import QtQuick.Layouts 1.1
import QtQuick.Window 2.0
Window {
id: mypopDialog
title: "MyPopup"
width: 300
height: 100
flags: Qt.Dialog
modality: Qt.WindowModal
property int popupType: 1
property string returnValue: ""
ColumnLayout {
anchors.fill: parent
anchors.margins: 10
RowLayout {
Layout.fillWidth: true
Layout.fillHeight: true
spacing: 20
Image {
source: popupType == 1 ? "combo.png" : "edittext.png"
}
Loader {
id: loader
Layout.alignment: Qt.AlignRight
Layout.fillWidth: true
sourceComponent: popupType == 1 ? comboboxComponent : editboxComponent
property string myvalue : popupType == 1 ? item.currentText : item.text
Component {
id: comboboxComponent
ComboBox {
id: comboBox
model: ListModel {
ListElement { text: "Banana" }
ListElement { text: "Apple" }
ListElement { text: "Coconut" }
}
}
}
Component {
id: editboxComponent
TextEdit {
id: textEdit
}
}
}
}
Rectangle {
height: 30
Layout.fillWidth: true
Button {
text: "Ok"
anchors.centerIn: parent
onClicked: {
returnValue = loader.myvalue;
mypopDialog.close();
}
}
}
}
}
Here I use Loader
to load appropriate content according to popupType
property (1 - combobox, 2 - textedit)
So now you can use this file in any place where you want.
import QtQuick 2.2
import QtQuick.Controls 1.2
import QtQuick.Layouts 1.1
import QtQuick.Window 2.0
Button {
text: "Test dialog"
onClicked: {
var component = Qt.createComponent("Popup.qml");
if (component.status === Component.Ready) {
var dialog = component.createObject(parent,{popupType: 1});
dialogConnection.target = dialog
dialog.show();
}
}
Connections {
id: dialogConnection
onVisibleChanged: {
if(!target.visible)
console.log(target.returnValue);
}
}
Here I use Connections
to get back some result from the dialog. If you don't need it just remove the Connections
item

I want to create a message dialog in the following way
For example:My combobox has 2 name, “chkbx”(symbolic name for the checkbox), “txtedt”(symbolic name for the text field).
Whenever i select chkbox or txtedt from combobox drop down list, then my combo box should connect me to actual checkbox and textedit element respectively.
I have a “show dialog” button on status bar when i press that button it should popup selected option(checkbox or line edit)
Please suggest me how can i do it.
EDIT Here is the code and the problem i am facing with combobox options is, neither i am not able to get icons in my message dialog nor i dont know how i can see checkbox or line edit in message dialog, i am a beginner and struggling to explore the tricky ways used in QML..

User almost 10 yearsThanks a lot, this was really helpful, gave me an idea how i can proceed. Y i am getting error:Unexpected token `if' in the if (component.status === Component.Ready) line, is it working fine on your system ?

folibis almost 10 yearsyou just need to put it inside some event handler or function. for example:
Button { onClicked: {here all the code ... var component = ...}}
. See I updated my answer. -
User almost 10 yearsSorry but i could imagine that you have good expertise in QML. Can you please look at this question [stackoverflow.com/questions/25056883/…
