How to "freeze" code execution in "onClicked" slot?

[evgeny_123]

Hey all! I have such problem. I have a dialog and some buttons on it. One of these buttons is "delete". I want to ask user whether he really wants to delete data. So I decided to do a message box with 2 buttons: "yes" and "no". So, i made a dialog, put these buttons on it. I made a "dialog hider" with defined mouse area (to disable all clicks except my message box - so it became modal).

In "onClicked:" slot of my "delete button" i show a dialog hider, then i show a message box. This is all clear. But i don't know what to do next. Because code, listed after showing of message box, must be executed only after user presses "yes" or "no" button. I tried to like this:

MessageBoxQuestion {
		id: msgQuestion
.......
}
.....
SimpleButton {
        ....
        onClicked: {
            dialogHider.state = "show"
            msgQuestion.state = "show"
            msgQuestion.onPushedYes: {/*delete data*/}
.....
       }
.....
}

but it's not working because of "msgQuestion.onPushedYes:". I suppose properties won't also help me..... So could you give me an advise, what to do next and how to solve my problem?

Thank you very much!

So does anybody know, whether there is a way to create MessageBox with its normal behavior? I mean how to make it waiting for user reaction? Or it can't be done in qml?

There is some kind of Dialog in thsi code that might help you.

Yeah, thanks! There is a dialog.. But it is like popup and there is no need to wait a user reaction.... So it is not that thing what i need ((

you can emit some signal on Yes/No button and can catch those signals to resolve the issue.

I've already tried to do so... But i don't understand how to make it working:

//file MessageBoxQuestion
Rectangle {
		signal pushedYes
		signal pushedNo
.......
		//has 2 buttons and when they are clicked, then these 2 signals are emitted
}

//file my dialog
Rectangle {
	id: listDialog

	MessageBoxQuestion {
		id: msgQuestion
	}
....
	SimpleButton {
		id: deleteData
        	....
        	onClicked: {
            		msgQuestion.state = "show"
			msgQuestion.onPushedYes: {
				//delete data
			}
			msgQuestion.onPushedNo: {
				//do nothing
			}
.....
       }
.....
}

I tried this way, but it is not working because it is forbidden to write msgQuestion.onPushedYes: in onClicked of SimpleButton..

try like this..

//file MessageBoxQuestion
Rectangle {
signal pushedYes
signal pushedNo
.......
//has 2 buttons and when they are clicked, then these 2 signals are emitted
}

---------------------------------------------

MessageBoxQuestion {
id: msgQuestion
onPushedYesClicked:
{
}
onPushedNoClicked:
{
}

}

Ok, but how then i will know, from which place of my code this message box was shown? I mean if i have more than 1 place where i show this message box, how can i find out, that it was shown from "place 1", but not from "place 2"? Should i create a single message box for every question? Or should i create something like enumeration in messageBox. And in place, where i want to show this message box, i should set "enum param" to a some value, and in for example onPushedYesClicked slot i should check this param? What is the best way?

Thanks!
