Re: [gtk-list] Re: Odd behaviour on GtkEntry

I found a way to make the cursor display properly on these NDS terminals
now.
I don't know why it works (except for the terminals being stupid), but
it does.

Changing the lines in gtkentry.c from

	gdk_draw_line (drawable, widget->style->fg_gc[GTK_STATE_NORMAL],
			xoffset, INNER_BORDER,
			xoffset, text_area_height - INNER_BORDER);

to

	gdk_draw_line (drawable, widget->style->fg_gc[GTK_STATE_NORMAL],
			xoffset, 0,
			xoffset, text_area_height);

(i.e. lose the INNER_BORDER adjustment on the cursor draw), and it now
displays 
where it should. It is probably a taller cursor than it was designed to
be, but 
so far I haven't seen it display in the wrong position, and the size
difference 
isn't really noticeable.

Is there some reason to adjust the cursor to less than full height of
the entry?
(just hoping I won't have to patch each new version before installing on
this
machine:)

gtk_draw_line looks like it is just a wrapper around XDrawLine, with
some
sanity checks before calling it.
