You're overwriting the flags, it should be:
setWindowFlags(flags() | Qt::CustomizeWindowHint|Qt::WindowContextHelpButtonHint | Qt::WindowCloseButtonHint );Also, is for dialogs and you should read the documentation:
"Adds a context help button to dialogs. On some platforms this implies Qt::WindowSystemMenuHint for it to work." -
