Dear all,

this is a cross-post from FXRuby-users’ mailing list. Since an earlier  
post  
from somebody else today got a response on the Ruby mailing list, which  
hadn’t got a response on a more restricted list, I felt encouraged to  
try  
again, too 🙂

How do you set the background color of a FXCombobox ?  
I have a Combobox, which should have a white background  
color, yet it somewhat strangely inherits the gray  
color of the frame it sits in.  
I have tried to correct this by setting

p = $settingsFrame  
p.recursive{|w|

# w.baseColor=STD\_BACK\_COLOR

next if w.kind\_of? TextField  
next if w.backColor==HEADER\_COLOR  
if /ComboBox/.match(w.type.to\_s)  
w.baseColor=WHITE\_BACK\_COLOR  
w.backColor=WHITE\_BACK\_COLOR

else  
w.backColor=STD\_BACK\_COLOR  
end  
}

for WHITE\_BACK\_COLOR=FXRGB(255,255,255),  
and STD\_BACK\_COLR=FXRGB(128,128,128)

but this changes the background color from gray to white only if I  
click on  
the combobox to show a dropdown of them. Then , everything becomes  
white, but after that, it turns to gray again.

Thank you for your help,

Axel

You’d probably need to change the background color of the FXTextField  
widget that’s a child of the combo box.
