QT to center a window (or control)

The code is as follows:

[CPP]View Plaincopyprint?

2. Xxx::xxx (qwidget *parent/ * = 0 */)
4. {
6. ..................
8. //Note that resize must be placed in front of this code
10. Resize (300, 300);
12. int CX, CY;
14. //When the parent is empty, the window is displayed in the center of the desktop
16. if (NULL = = parent)
18. {
20. CX = (qapplication::d esktop ()->width ()-width ())/2;
22. cy = (qapplication::d esktop ()->height ()-height ())/2;
24. }
26. //Otherwise, the control is displayed in the center of the parent part
28. Else
30. {
32. CX = (Parent->width ()-width ())/2;
34. cy = (parent->height ()-height ())/2;
36. }
38. Move (CX, CY);
40. ....................
42. }

This code is too often used, and then send up and share it with you, hehe.
