QWizardPage executing function after initializePage() is called and WizardPage is shown
Message 1 in thread
Hello !
I have a simple question:
I have a wizard with some QWizardPages.
At the last Page, I want that a progressbar is shown and executing a
task (function).
The pages are created at the ctor of QWizard and the progressbar is
created in QWizardPage::initializePage().
The problem is, that if I start the task (function) in initializePage(),
the wizardpage is shown after the task is finished.
But I want that the wizardpage is shown and than start the task, how can
I make this work easy ?
Thanks a lot for helping !
Heiko

I'm not sure if this helps, but judging from my experiences, this sort of
problems can be fixed by starting the function a bit later (at the end of the
current event queue), giving Qt time to show() the widget. This can be done
with something like
QTimer::singleShot(0, your_object, SLOT(your_function())
in the initializePage() routine.
To correctly update the progress bar, you should also call
qApp->processEvents() every now and then within this function...
