How to access the "?" menu button in QWidget
Hallo Everybody,
i have a simple dialog-widget made in Designer. QDialog inherits QWidget, right?
Code:
{
public: ...the constructor
private:
UI:inputdialog *ui;
...
Normally I take the rough road and code them on my own, but I gave it a try. Now I have a menubutton wich looks like "?", which certainly means "help" or "about".
When I press this button the widget seems to fall in an undefined state. The mousecursor shows the "forbidden" sign an then it turns into a "beam". After some seconds it returns to normal. Therefore I would not just ignore it.
Question: How do I access this thing? Fill it with actions, switch it off, ..whatever. I didn't find an entry in the prefs of my widget in the designer. Nor I'm very familiar with this product.
Any help as always highly appreciated.
regards, Lars

Without screenshot this is a guess, but this could be a "What's This" button.
See QWhatsThis.
Usually that would not be enabled by default though, maybe you entered some what's this data for the dialog or some of its widgets?

Yes. This is what I found out in the meantime.

No. I didn't activate anything, nor have entered any information. I never use whats This. I prefer tooltips. But if I do so, because now I know it's the whatsThis-feature, and use it, the strange behaviour turns into some not very pleasant different behaviour.
Somehow I cannot upload screenshots. Perhaps it's the firewall blocking here. Sorry, I actually tried but didn't say so explicitely.
The remaining question now is how to switch off and hide the "?".

Added after 36 minutes:
I found
Code:
setWindowFlags(windowFlags() & ~Qt::WindowContextHelpButtonHint);
Hard to find the right question sometimes.
Thanks Everybody.
