Claus DIETRICH reported a new bug.

Summary
-------

Gambas Button: No Background and Border Control with QT5

Type             : Bug
Priority         : Low
Gambas version   : 3.18
Product          : Development Environment


Description
-----------

1. The Button-property Background has no effect at all under QT5. 
2. The Button property Border causes the button to disappear entirely (except the button text) under QT5 if set to False. If set to True the button is visible but there is no border if the button is pressed.
3. When I try to change the background under Kubuntu and Gambas 3.17.90 the IDE crashes with the error message "[7] Overflow [gb.gui.base].GridView.UnmakeSpan.1910. The "ignore" button has no effect. 
There are no problems with above 1 and 2 if I use GTK3. A change of the theme from Mint-Y to Adwaita or Windows10 had no effect.
Let me know if I shall split it up into separate reports.
With best regards
Claus
