Solved minimize and context help buttons on my QDialog

[kaleem]

I would like to show both the minimize and context help buttons on my QDialog derived dialogs. I'm using Qt 4.2. and I can't seem to do it using setWindowFlags. I have my own dialog class that is subclassed from QDialog. In the constructor I call:

setWindowFlags( windowFlags() | Qt::WindowMinimizeButtonHint | Qt::WindowContextHelpButtonHint );
The minimize and maximum buttons show (as well as the close button) however the "?" help button does not. The only way I can show the help button is if I do not show minimize or maximize.

Any suggestions?

Thanks

I had this issue earlier too but never resolved it. I could not get the minimize/maximize buttons and the help button at the same time. If I had the min/max hint set, it always ignores the help hint. If I only set the hint for help, then I get the help button.

Hi and welcome to devnet,

Can you share your dialog setup code ?

Also Qt 4.2 ? Are you locked to that very old version ?

It is not possible for Context Help button and Maximize button to co-exist on Windows.
System does not allow it.

@SGaist sorry correction my QT version is 4.4.3 not 4.2
Following is my code in constructor of class which is inheriting QDialog
fl = Qt::Window | Qt::WindowContextHelpButtonHint | Qt::WindowMaximizeButtonHint
| Qt::WindowMinimizeButtonHint;
this->setWindowFlags(fl);
Thanks,

Hi
If you load the
http://doc.qt.io/qt-5/qtwidgets-widgets-windowflags-example.html
example

you will see that combination is not possible.
As @alex_malyu already pointed out. :)
