[Qt-interest] Windows that move together

[Atlant Schmidt]

John:

  I'm not sure I'm correctly envisioning these "windows that move
  together" but is there a reason why they can't be emplaced within
  a (possibly-transparent) Qt frame? That would make Qt responsible
  for keeping them all moving together.

Subject: [Qt-interest] Windows that move together

My company's application, that we are in the beginning stages of porting to Qt, has grouped windows- windows that move together, basically looking like separate windows but acting like one window.

Under Mac OS X Carbon, we use Macintosh window groups. On Windows, we have an emulation of window groups that basically just catches window move events and applies the moves to all the windows of the group.

I implemented such a scheme under Qt using an eventFilter that watches for QEvent::Move. It works OK on Windows, but on Macintosh the events are very much delayed. The grouped windows never move with the main window, and actually wait for a second's delay or so before they catch up.

I was wondering if anyone might have experience with QEvent::Move, and have a solution.

Thank you!
