TGLabel

ROOT
1

Hello,
So I have some problem when trying to change the
background, foreground, font, … in TGLabel: if label is TGLabel* then
the following operations left some text which I can’t get rid of:
label->SetTextColor (blue);
label->ChangeBackground (blue);
So normally I will expect this will left me with blue only
but it’s not the case
The following picture shows this (I hope):

And this thing stays there even if I change the font etc.
So how to get rid of this thing? And anyway it doesn’t seems
very normal. (working with 5.06/00)

Probably something have to be chainged in TGGC. I’ve already tried couple of things without success:)

I’m having the same problem. It is very annoying to read. I’ve attached a simple example
code. Any suggestions for how to fix it?

Hi Jimmy and Chris,

Chris’ example does not run on SLC3 and WinXP/cygwin versions of root, but I was able to reproduce the problem and will provide a fix after my current task is finished. I will keep you informed.

Cheers, Ilka
