Resizing programmatically QDialog: content gets stretched for a fraction of a second (Qt5)



  • Hello,

    I have a QDialog with fixed dimension (i.e. the user cannot resize it with the mouse). But depending on the context, I make several items visible and adjust the dialog's dimension (programmatically) in order to also display the now visible items. That works, except that the resize command (setFixedSize()) first scales its old content to fill the new dialog size (i.e. the item I made visible appear only afterwards). That wasn't the case before Qt5.
    I tried to temporarily disable the update with setUpdatesEnabled, but that didn't change anything. Any idea what I am doing wrong?
