[Solved] QDialog not display

DBoosalis

If I close QDialog from hitting the window managers close button on linux I am unable to display it again. This is not ture if I close it with QDialog button. This is on Linux with Qt 5.3.1. Does any one know the secret sause to make dialog reappear (Note this is a standard model dialog)

Here is my code to show the dialog:

@console.log("SHOW Server Confilg Dialog");
mydialog.open();
mydialog.visible = true;@

I always get the console messge but not the dialog

Thanks in aadvance for any help

Hi,

Do you have something like

@
void showMyCoolDialog()
{
MyDialog mydialog;
console.log("SHOW Server Confilg Dialog");
mydialog.open();
mydialog.visible = true;
}
@

?

If so, your dialog is destroyed at the end of the function.

No, I have it as written the declaration is outside the call. But even if I did why would it not create a new instance.

This is rather strange behavior if you ask me,

SGaist

What is your exact code ?

@ApplicationWindow {
id: mainwindow
title: "FixHarness"
visible: true
width:600
height:600
property bool connectedToServer:false
Dialog {
id:mydialog
visible:false
title: "Blue sky dialog"
standardButtons: StandardButton.Save | StandardButton.Cancel
}

function showServerConfigDialog()
{
    console.log("SHOW Server Confilg Dialog");
    mydialog.open();
    mydialog.visible = true;
}

Action {
id:configureServerA
text: qsTr("Configure")
iconSource: "qrc:/images/32x32/config.png"
iconName: "configure"
tooltip: "Server settings"
onTriggered: {
console.log("SHOW SERVER....");
mainwindow.showServerConfigDialog();
}
}
}

Try this. I don't really understand your problem.

@import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Dialogs 1.2

ApplicationWindow {
id:root
visible: true
width: 640
height: 480
title: qsTr("Hello World")

menuBar: MenuBar {
    Menu {
        title: qsTr("File")
        MenuItem {
            text: qsTr("&Open")
            onTriggered: {
                console.log("Open action triggered");
                showServerConfigDialog();

            }
        }
        MenuItem {
            text: qsTr("Exit")
            onTriggered: Qt.quit();
        }
    }
}

Text {
    id:textHW
    text: qsTr("Click me to open server dialog")
    anchors.centerIn: parent
    MouseArea {
        anchors.fill: parent
        onClicked: showServerConfigDialog()
    }
}

Dialog {
    width: 350
    height: 200
    id:mydialog
    visible:false
    title: "Server dialog"

    Text {
        id: dialogText
        text: qsTr("Server dialog")
    }



    standardButtons: StandardButton.Save |  StandardButton.Cancel
    onAccepted: {
        console.log("Save server dialog");
        root.title = qsTr("Save server dialog");
    }
    onRejected: {
        console.log("Cancel server dialog");
        root.title = qsTr("Cancel server dialog");
    }
}


function showServerConfigDialog() {
    console.log("Show server dialog");
    mydialog.open();
}

}

Hi

I have some issue related to this. If I change the code from previous to the following. When I clicked on OK button I got immediately console.log ("Save server dialog"); but textHw. text changed after I moved the mouse. If I clicked on textHw the textHw.text changed immediately to "Change text".
There is also some issue that menu bar disappearing during window resize.

I modify
@
// onClicked: showServerConfigDialog()
onClicked: textHW.text = qsTr("Change text");
@

and

@ standardButtons: StandardButton.Save | StandardButton.Cancel
onAccepted: {
console.log("Save server dialog");
textHW.text = qsTr("Save server dialog");
root.title = qsTr("Save server dialog");
}
onRejected: {
console.log("Cancel server dialog");
textHW.text = qsTr("Cancel server dialog");
root.title = qsTr("Cancel server dialog");
}@
