TK:PixMap and Mask?

[xhonzi]

I created a pixmap that I thought would have a transparent background. When it's displayed on the Form, it shows the background as a grey colour, not transparent. I'm familiar with using masks with bitmaps, and was wondering if I needed/could do the same with pixmaps. I know you can use .png's with transparencies (and no mask).

Any help?

Tk gives a background color to all widgets. iirc if you have a PNG with transparency and put it in a Label widget, and place the Label on top of something else (so that you should be able to see through the PNG to the widget beneath it)... you won't see through the PNG, because it would have a background color, which would probably be the same color that's behind all other Label widgets (default system window color, unless you specify otherwise).

The only way I've found to make transparent images appear on top of other images and widgets is to put all of them inside of a Canvas object. See Tk::Canvas.

Thanks, I'll look into Canvas. I've been meaning to for a while.
