Problem with Dark Theme and Foreground

[CD <dessere.claude@xxxxxx>]

Hello,

If I use gb.gui.qt, the Gambas IDE displays the dark theme,   
but the forms at runtime
do not display the dark theme
and correctly display the Foreground property of the controls.

However,
if I use gb.qt5, the Gambas IDE displays the dark theme,
the forms at runtime display the dark theme
but do not display the Foreground property of the controls.

Is this normal?

Attached project

Regards
