Drawable and Colormap question...!!

[Kumar Siddharth <kumarsiddharth tataelxsi co in>]

Hi,

I am new to GTK. What will happen(say visually) if the following code throws
assertion:

 pixmap = gdk_pixmap_new(NULL,x,y, gdk_rgb_get_visual()->depth);
 gdk_drawable_set_colormap(pixmap, gdk_rgb_get_colormap());

Assertion: depth of drawable is not equal to the depth of colormap...!!

Here the pixmap depth is not equal to the depth of colormap, so the colormap
can't be set. But i am not having any idea regarding the effects of this
assertion. I have a big code which is using these two lines and throwing
assertion on GTKDFB.
Will there be any problem related to colors..??

Regards,
Siddharth
