QMainWindow and its children vs visibility at focus change/minimizing



  • Hello,

    I have a QMainWindow instance with bunch of QDialogs and QWidgets set as its childern. User may open them by clickin some actions on menubar. What is happening, that in fact I don't want to be happenin:

    • when I minimize main window its children are minimized as well (I guess because they are its children)
    • when I have some dialog/widget opened (visible) it stays ON TOP of the main window even if I click in the main windows area (focus thingy i guess)

    My question is:

    • is there a non-complicated solution to fix this behaviour? Idk.. like settings a flag? something like that, I cannot find anything in docs (at least so far)

    What I came across during searching:

    • 'orphaning' children :D (setting their parent to Q_NULLPTR) inside stateChanged event and turning it back again depending on the event type.
      I did not test/used it yet since out of curiosity I wanted to ask you guys about it? Do you think above solution is sensible enough to be used or are there any other better ones?

    Best Regards,
    M.

    Hi
    Have you tried simply not to give the dialogs a parent?

    MyDialog * dia= new MyDialog ();

    You will need to delete them your self when app is closing.



  • Simplest solutions are the best - thank you!
    I kinda feel really dumb now :D
    Anyway - solved.

    Well often :)
    There was a thread not so long ago talking
    about how to delete the dialogs later.
    If you make them members, its pretty basic.



  • Can you point me to this thread (just in case - I may find something usefull there)?
