Hey,

I have troubles on replacing items on resizeEvent of the QMainWindow - I am not using any layout, i just recalculate the new positions on resize.
If the window is resized slowly there are not any troubles but if i resize it very fast by moving the mouse in crazy ways i get weird results....
I added a "before resize" and a "after resize" screenshot to illustrate the problem.

The Code looks like follows:
Qt Code: 
  1. void ClientMainWindow::resizeEvent(QResizeEvent * event){
  2. 		int heightPositionCorrection = (event->size().height()-event->oldSize().height())/2;
  3. 		int widthPositionCorrection = (event->size().width()-event->oldSize().width())/2;
  4.  
  5. 		ui.controlAirCondition->setGeometry(
  6. 			ui.controlAirCondition->geometry().x()+widthPositionCorrection,
  7. 			ui.controlAirCondition->geometry().y()+heightPositionCorrection,
  8. 			ui.controlAirCondition->geometry().width(),ui.controlAirCondition->geometry().height());
  9. 		ui.controlAlarmSystem->setGeometry(
  10. 			ui.controlAlarmSystem->geometry().x()+widthPositionCorrection,
  11. 			ui.controlAlarmSystem->geometry().y()+heightPositionCorrection,
  12. 			ui.controlAlarmSystem->geometry().width(),ui.controlAlarmSystem->geometry().height());
  13. 		ui.controlBlinds->setGeometry(
  14. 			ui.controlBlinds->geometry().x()+widthPositionCorrection,
  15. 			ui.controlBlinds->geometry().y()+heightPositionCorrection,
  16. 			ui.controlBlinds->geometry().width(),ui.controlBlinds->geometry().height());
  17. 		ui.controlHeating->setGeometry(
  18. 			ui.controlHeating->geometry().x()+widthPositionCorrection,
  19. 			ui.controlHeating->geometry().y()+heightPositionCorrection,
  20. 			ui.controlHeating->geometry().width(),ui.controlHeating->geometry().height());
  21. 		ui.controlLights->setGeometry(
  22. 			ui.controlLights->geometry().x()+widthPositionCorrection,
  23. 			ui.controlLights->geometry().y()+heightPositionCorrection,
  24. 			ui.controlLights->geometry().width(),ui.controlLights->geometry().height());
  25. 		ui.controlMusic->setGeometry(
  26. 			ui.controlMusic->geometry().x()+widthPositionCorrection,
  27. 			ui.controlMusic->geometry().y()+heightPositionCorrection,
  28. 			ui.controlMusic->geometry().width(),ui.controlMusic->geometry().height());
  29. 		ui.controlVideo->setGeometry(
  30. 			ui.controlVideo->geometry().x()+widthPositionCorrection,
  31. 			ui.controlVideo->geometry().y()+heightPositionCorrection,
  32. 			ui.controlVideo->geometry().width(),ui.controlVideo->geometry().height());
  33. 		ui.configScreen->setGeometry(
  34. 			ui.configScreen->geometry().x()+widthPositionCorrection,
  35. 			ui.configScreen->geometry().y()+heightPositionCorrection,
  36. 			ui.configScreen->geometry().width(),ui.configScreen->geometry().height());
  37. 		ui.controlPlaceholder->setGeometry(
  38. 			ui.controlPlaceholder->geometry().x()+widthPositionCorrection,
  39. 			ui.controlPlaceholder->geometry().y()+heightPositionCorrection,
  40. 			ui.controlPlaceholder->geometry().width(),ui.controlPlaceholder->geometry().height());
  41. }
