QT: Incorrect Client Height with Menu
Posted: Wed Jan 07, 2026 9:05 pm
Under Linux with the QT subsystem, the calculation of the client height of a window does not work correctly when the window has a menu.
With GTK, it is correct.
The bug has existed since version 6.12.
In the example code, you can enable or disable the menu, toolbar, and status bar using the three global variables to see the error. The EditorGadget should occupy almost the entire available space.
