"option" acts on the "option database".
Chris Nelson notes:
> I've changed to: > > # Why do these affect selection? > option add *Entry.background red widgetDefault > option add *Entry.foreground blue widgetDefault > > entry .e > pack .e > > # Why is this only when the button is active? > option add *Button.background red widgetDefault > option add *Button.foreground green widgetDefault > > button .b -text Exit -command exit > pack .b > > And now the options seem to have no effect.
Based on a clue from Jeff in another conversation, I found that setting the priority to startupFile, instead of widgetDefault, was enough to get this to work. It seems Solaris' CDE does some funky color stuff.
Jeff replies:
More accurately, Solaris sets the equivalent of:
*foreground and *background
in the X defaults. Very lame way to control L&F, but that's what they chose. Those wanting to get around this can also see the solutions in the Tk Usage FAQ:
