Drawing

["Alexander S.Kresin" <alex belacy belgorod su>]

Hello All,

 please, help me with some basic problems, related to drawing.
 
 What I want is to draw some things on the drawing_area with a certain
 color - red rectangle, for example.

 this is what I wrote in expose_event handler:

 ...
 GdkDrawable * hWnd = widget->window;
 GkdGC * hDC = widget->style->fg_gc[ GTK_WIDGET_STATE( widget ) ];
 GdkColor color;
 gdk_color_parse( "FF0000", &color );
 gdk_gc_set_foreground( hDC, &color );
 gdk_draw_rectangle( hWnd, hDC, 0, 0, 0, 30, 30 );

 I get this rectangle, but of lilac color, and all other widgets in a
 window became lilac ...

 What I need to have only my rectangle in the drawing_area with a red
 color and then, for example, some line there in any other color ?
 

Regards,
 Alexander
