Qt::Popup with titlebar

[keyur259]

Hi,

I have a subclass of QWidget. And I have set windowFlags to Qt::Popup in the constructor. But when popup widget is displayed, it comes without titlebar. I have also tried Qt::Popup | Qt::WindowTitleHint. But it's still displayed without titlebar.

How can I get popup with title bar?

Please reply.

Thanks & Regards,
Keyur Shah

With Qt::Popup you wont get the title bar.
Dont set any flags, and you will get the widget with a title bar. You can also use QDialog , or QWidget with Qt::Tool flag set,, whatever suits you.

Thanks for your reply.

Oh... But none of other flags gives me what i wants.
QDialog are providing only application specific functionaliy.

I want my widget to close if user clicks outside the widget or better outside the application too.

So how can I get such things without using Qt::Popup flag?

Well, if thats the case, I can think only of the following for now -
Draw the title bar yourself in the paintevent of your widget. And you can have the Qt::Popup flag set on your widget too

Is there any method using which I can draw titlebar of widget by myself?

[aamer4yu]

QStylePainter::drawComplexControl(QStyle::CC_TitleBar,option);

Still it is diaplyed without titlebar.

I have written following code in paintEvent

QStylePainter painter( this );
QStyleOptionTitleBar option;
painter.drawComplexControl( QStyle::CC_TitleBar, option );

Please let me know if I am missing something.

[aamer4yu]

try setting option.initFrom(this);
But I doubt if QStyle will permit you draw a title bar on a Qt::Popup widget.

You can try setting the QStyleOptionTitleBar::titleBarFlags and see if draws.

How to set QStyleOptionTitleBar::titleBarFlags???

Do you mean set the widget->setWindowFlags(Qt::WindowTitleHint) ?

What is the exact functionality you want and get with Qt::Popup and you can't get with other flags?

[keyur259]

With Qt::Popup, If I click anywhere including outside application, only the popup will be dismissed and no other window has any effect.
