Collapzable widget

[marc2050]

Hi,

How do I create a widget that has a tiny little arrow that, when user clicks on it, it will collapse the widget into just a title bar. I see this sort of collapzable interface in other applications before. I could not find any examples or demo that show this in QT.
Any pointer please.

Thank you.

Connect a checkable button that will serve as your "arrow" and connect its toggled(bool) signal to a setVisible(bool) (or setHidden(bool)) slot of the widget serving as a "body" of the widget you want. Or use QwwTaskPanel from wwWidgets if it suits your needs.

i think if u just resize your widget to a minimum height (0 maybe) then u can get the desired effect.

EDIT: too late

EDIT2: if he hides the toplevel widget then the whole window with title bar will hide.

So we're saying there is no built in function. But rather has to be achieved through some kind of tricks?

No; they're saying that the functionality to do this is present, and that you simply have to write code to make use of it.

Nobody said he should use top-level windows. That's a different mechanism.

I thought he was talking about toplevel when i saw the "Title bar" and the collapse behavior which is present in many gnome themes.

Collapsing (or actually "shading") a window is a feature of the windowing system and not the application. You can only hint the OS to shade the window by setting Qt::WindowShadeButtonHint.

yes.. and i was under impression that he want to mimic that behavior where it is not available (Windows).
