the second combobox only changes a get for a btnbmp
the problem is that the procedure recreates the dialog elsewhere and if you use oDlg:center() it puts it back in the center
but a flash is visible, many times you see the dialog in the left corner and then in the center .
apparently nothing happens if there is only the combobox in the dialog, if there are the other controls (about 20) you have the perception of the flash
I haven't found any solutions
a small sample
- Code: Select all Expand view RUN
- #include "FiveWin.ch"
#include "Constant.ch"
