How to make frameless widget as a window or dialog

[ainne810329]

I made a frameless widget which has its own titlebar. When this widget has a parent widget, it doesn't act as a separate window anymore, but I want to have it popup as a dialog. Unfortunately I can't minimize, maximize it. It stays inside the parent widget frame. How can I make this frameless widget still act as an independent window or dialog when it has a parent widget?

The code looks something like this:

#include <QtGui>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QMainWindow mainWin;
mainWin.show();

FramelessWidget myWid(&mainWin, Qt:ialog | Qt::FramelessWindowHint);
myWid.show();

return app.exec();
}

Anyone has any ideas?

Hi

ok first of all, what kind of widget is your FramelessWidget? QWidget? QDialog? QObject?
when its from QDialog, then u dont need to set a parent in your constructor:

main.cpp:
...
FramelessWidget myWid(Qt::Dialog | Qt::FramelessWindowHint);
myWid.show();

main.cpp:
...
FramelessWidget myWid(Qt::Dialog | Qt::FramelessWindowHint);
myWid.show();

To copy to clipboard, switch view to plain text mode 

but then u have to change your constructor in your framelesswidget.cpp to:

FramelessWidget(..., QWidget* parent = 0);

FramelessWidget(..., QWidget* parent = 0);

To copy to clipboard, switch view to plain text mode 

because arguments with default-values must be at last positions in the constructor.

if your FramelessWidget is inhertide from QWidegt, then u need a QDialog or QMainWindow like:

main.cpp:
{
...
QMainWindow mainWin;
mainWin.show();
 
QDialog dia;
FramelessWidget(&dia, Qt::Dialog | Qt::FramelessWindowHint);
dia.show();
 
return app.exec();
}

main.cpp:
{
...
QMainWindow mainWin;
mainWin.show();

QDialog dia;
FramelessWidget(&dia, Qt::Dialog | Qt::FramelessWindowHint);
dia.show();

return app.exec();
}

To copy to clipboard, switch view to plain text mode 

this code snippet creates one MainWindow and one Dialog-Window.

i hope i could help you

with best regards

First, thank you very much for your respond.

The FramelessWidget is derived from QWidget indeed, by using a QDialog as a parent of my frameless widget, the purpose to have custome title bar and borderless dialog can not be achieved anymore.

Secondary, I do want this frameless widget to be a child dialog of the mainwindow, so it stays on top of the mainwindow and when the mainwindow is minimized, the frameless dialog is also minimized.

Any idea how I can achieve my goals?
