QDialog的raise（）函数如何不起作用？

Question

From my QMainwindow I am opening a second QDialog window when a pushbutton is pressed.This is my code

  newFile = new Dialog(); if(fStatus == 0) { newFile.show(); fStatus = 1; } else if(fStatus == 1) { newFile.raise(); } 

What I am trying to do is if the QDialog window is already open and the push button is pressed again I want my QDialog window to move to front.

I have tried same with Qwidget form it is working but Qdialog raise(); is not working,but in case of Qwidget I am not able not capture the Qwidget destroyed signal on closing of the widow properly.

Answer 1

I didn't tested it but from what I read I found this :

yourQWidget->show();
yourQWidget->activateWindow();
yourQWidget->raise();

How to Bring the Widget Bring to front in QT?

QDialog *yourQDialog = new ...
yourQDialog->setWindowFlags(yourQDialog->windowFlags() | Qt::WindowStaysOnTopHint);
yourQDialog->show();

Bring QDialog to front

Also loook at this question: Bring window to front -> raise(),show(),activateWindow() don't work
