[Qt-interest] How to set up multiplle number of GUI

[Ross Bencina]

Hi Vijay

Perhaps you have not explained yoru requirements well, but...

For two GUIs yes, you need two top level windows (QWidgets), but you don't need two QApplication instances or two event loops. In Qt the two top level windows can easily share the same QApplication and event loop. In any case, you are only allowed to have one QApplication per process, that can't be avoided.

If you really do need things to be completely separate you could create two separate applications and a third one which launches them.

Ross.

  Hi,
  I want to create a Qt Aplication in which GUI contains two buttons
  Clicking on these two buttons will set up different GUI as they refer to objects of different classes.
  For this, I have to start separate event processing loops for the two classes.
  This means i need to create separate QApplication objects for the two classes
  but, QApplication object requires argc and argv as its parameters
  So, how can i achieve my requirements
  please help.
