BUG (in gb.qt?) Button.Background

[Patrik Karlsson-3]

_Gambas 2.7_

Hello,
I have noticed a problem when trying to change the color of a button
in run time.

When I place a button on a form at design time, I'm able to change its
color, but trying to change during run time will not work.
I added this

PUBLIC SUB Form_Open()
  DIM hBut AS NEW Button(ME)
  hBut.BackColor = Color.Red
END

At program start, I can see the button flash in red, and after that,
return to default color.
The button made with design gets to keep its color.

  { Button1 Button
    MoveScaled(5,15,16,3)
    Background = &HFF21C4&
    Text = ("Button1")
  }

When I make this project a gb.gtk, it is all ok.

Which KDE widget style do you use? Can you check that you have the same
behaviour with another KDE widget style?

This is interesting.
I had the defalut QtCurve in Kubuntu Hardy. I got somewhat different
behaviour when change between other styles.
Plastic was thes best, a clicked red button became dark red.

What does this mean?
Is the problem outside of Gambas? If so, how come setting the color
in design mode works, and run time does not?
