How to open dialog box on top of the application if two screen are connected?

mrjj

Hi
Im not 100% sure Qt::SplashScreen is compatiple with Qt::Dialog flag

Qt::SplashScreen 0x0000000e | Window Indicates that the window is a splash screen. This is the default type for QSplashScreen.

Normally used with QSplashScreen widget.

mrjj

maybe try with
dialog->setWindowFlags(Qt::Dialog | Qt::SplashScreen);

@mrjj it is create previous issue.

@Yash001
but why you need Qt::SplashScreen ?
and modal dialog ?
cant you just use the dialog ?

@Yash001
Similarly to @mrjj , have you considered using QSplashScreen (http://doc.qt.io/qt-5/qsplashscreen.html), maybe it doesn't have these problems?

I am using Qt::SplashScreen because of I wanted show dialog on the top of all screen. This dialog is show whenever specific signal is generated from Hardware Connection. if hardware is connected with PC before opening our Software then dialog will open after Software Open. and control need to transfer on dialog box. (at this time user should not access any other page).

I have not idea what is model Dialog.

@Yash001
Modal dialog means user cannot click on mainwindow behind dialog.
Sometimes also called blocking.
comes when using exec() versus show().
