TGLOveralyButton::SetTextColor(Pixel_t color)

ROOT

Dear Rooters,

I’m trying to change the text color of my TGLOverlayButton to kRed but it doesn’t work.
When I try SetTextColor(kRed) the text becomes black with a white contour, what I’m missing?

Thanks for any kind of explanation.
Cheers.

Hi,

The argument of TGLOverlayButton::SetTextColor() is of type Pixel_t (see the class documentation)
Then you should try with SetTextColor(0xff0000) (for red)

Cheers, Bertrand.

Hi Bertrand,

Thanks very much, it is in hex code, and Gimp doesn’t help me :slight_smile: !

Thanks another time,
Cheers

Well, it is a widely used format (RGB)… So to be more clear the format is 0xRRGGBB, from 0x000000 (black) to 0xffffff (white)
I think it is possible to get the hexadecimal color value in Gimp: Opening a color dialog, you have a “Hex Triplet” field with the hexadecimal value of the selected color (at least with Gimp 2.05)
And you’re welcome :slight_smile:

Cheers, Bertrand.
