I have discovered the gtk_draw_box function that will almost do what
I want except it draws a border around the box. If I use
gtk_draw_flat_box
it does not draw the border but the pixmap is only 100x100 so I have to
do
the following,
int x, y, w, h;
GtkStyle *style;
x = drawingarea1->allocation.width;
y = drawingarea1->allocation.height;
w = x/100;
h = y/100;
style = gtk_widget_get_style(machine);
for (x=0; x<=w; x++)
for (y=0; y<=h; y++)
gtk_draw_flat_box(style, drawingarea1->window,
GTK_STATE_NORMAL, GTK_SHADOW_NONE, x*100, y*100, 100, 100);
I don't know if this is the best way of doing this.
The question is can I be sure that the pixmap will always be 100x100 in
size
i.e. is it a condition of creating a theme, and if not how do I work
out how
big it is to adjust the code above.
