shree_121

Hello, In my application i have 2 windows when i ran my Qt widget program it built correctly . In application output for first window there is no the cancel 'X' in the right-upper corner and also no title displayed which i set using setWindowtitle() but it appears in second window. So how to get cancel option for first window too?

Hi
Do you call setWindowsFlags or something?
Also this is on windows ?

shree_121

hi@mrji, I called setWindowTitle() and setFixedSize(). This is on centos 7.

hi
Just to rule out a broken installation.
Could you try a default GUI project?

shree_121
