hello guys.
I have some question about qmdisubwindow.
I have to make subwindow with custom titlebar.
actually, I have made mainwindow with custom titlebar and frame.
so I think I can make subwindow same way.
But, mainwindow and qmdisubwindow is not operate same way.
when I made custom mainwindow using
setWindowFlags(Qt::FramelessWindowHint);
setWindowFlags(Qt::FramelessWindowHint);
To copy to clipboard, switch view to plain text mode
I can't resize mainwindow, so I add some code for resizing.
and using
setWindowFlags(Qt::FramelessWindowHint);
setWindowFlags(Qt::FramelessWindowHint);
To copy to clipboard, switch view to plain text mode
at the qmdisubwindow,
I can resize subwindow.
unfortunately, provided policy is not I want.
So I want to add my own code for resize like mainwindow.
for that, I remove provided resize function of subwindow.
any hint? please help!
Added after 20 minutes:
A minute age, I saw the other mdiarea example.
and there's subwindow operate correctly, so I miss the other site..
I'm so confused.. 
anyway sorry!
you just pass this question!
================================================== ====================================

It's my mistake that I think sub window is non-resizable.
If I double-click the widget, I can resize the widget.
so, I use code this :
subwindow->setfixedsize();
subwindow->setfixedsize();
To copy to clipboard, switch view to plain text mode
but If I double-click the widget, mouse-cursor shape is still changed.
I want cursor shape will not changed too.
any help?? please...
