Hi Sergey,

Changing the .color property in this case is a bit of a pain. Here is a

sample of how I would have to do it

procedure myRich.setEnabled(value:boolean)

begin

if value=false then color:=clGrey;

end

but now I have forgotten the original color. So I have to create a temp

variable to remember the enabled color. Ok, no big deal. But now what

happens if someone changes the .color property programatically to clRed

while the button is disabled. Then the color will change from clGrey to

cl_red, but when the richview becomes enabled, it will go back to the

original color. So now I have to override setColor as well as

setEnabled.

I am not sure if there is an easy solution for this, aside from finding

the place where you actually paint the background on and changing your

code.

A suggestion (stolen from virtualStringTrees). He has a property called

.Colors which in your case would be like

TRichColors=class(Tpersistent)

property BackgroundColor:tColor;

property DisabledBackgroundColor:tColor;

property UnfocusedBackgroundColor:tColor;

etc.

end;

That way, you can add colors for different states of the component and

use them as needed. You can add states, as you need them.

Just a suggestion, in the meantime, I will try to figure something out.
