Hi all,
I'm trying to draw some text onto a drawing area in GTK+2.0.
Now, the docs say I can't use gdk_draw_text() because it's deprecated. I
have looked around for other ways of drawing text and it looks like I
have to use gdk_draw_layout() instead, which means I have to get
involved with Pango.
As far as I can tell, in order to get a PangoLayout I first need to make
a PangoContext and then create a PangoLayout from this context.
kinda like this:
#include <pango.h>
#include <gtk.h>
{
PangoContext *pContext;
PangoLayout *pDrawingAreaLayout;
pContext = pango_context_new();
pDrawingAreaLayout = pango_layout_new(Context);
pango_layout_set_text(pDrawingAreaLayout, "Here is some text", -1);
gdk_draw_layout(widget->window, NULL, 0, 0, pDrawingAreaLayout);
}
The problem is that I can't call pango_context_new() because the
compiler says it's an undeclared function. This seems to be because in
pango-context.h there is this:
#ifdef PANGO_ENABLE_BACKEND
PangoContext *pango_context_new (void);
void pango_context_set_font_map (PangoContext
*context,
PangoFontMap *font_map);
#endif /* PANGO_ENABLE_BACKEND */
Can anyone explain to me what is going on here? Have I got it
completely wrong or what?
Cheers in advance,
Mark Wheaton
