Hello,
it seems backColor in sheetwindows does not work: in the IDE I set to black the backColor of a sheetwindow, but when the windows shows, the backcolor is more or less the backcolor of the parent window.
I could fix the problem using the sheetwindows’ paint event:
g.forecolor = color.black
g.fillRect 0,0,g.width,g,height
Is it the expected behavior in Mojave Xojo 18r4?
Thanks
