Re: xpm with transparency to a button

[Matt Flax <flatmax mimosaacoustics com>]

I have started using cairo on this topic,

With the following code, the image is not produced at the desired 
location .. can anyone point out what I am doing wrong ?

Is it something to do with the locations x and y ?

#include "T6.xpm"

gboolean on_expose_event(GtkWidget *widget, GdkEventExpose *event, 
gpointer data){

    int width, height, x, y;
    GdkPixbuf *tipGDKPixBuf = gdk_pixbuf_new_from_xpm_data(T6);
    width=gdk_pixbuf_get_width(tipGDKPixBuf);
    height=gdk_pixbuf_get_height(tipGDKPixBuf);

    gtk_widget_set_size_request(widget, width, height);

    gdk_window_get_position(widget->window,&x,&y);

    cairo_t  *cr=gdk_cairo_create(widget->window);
    gdk_cairo_set_source_pixbuf(cr, tipGDKPixBuf, x, y);
    cairo_paint(cr);
    cairo_destroy(cr);

    return FALSE;
}
