Hi folks,
Just need to pick your brains about somethings!
I've got this few lines of code scattered around in my code (in this
order)....
gtk_signal_emit_by_name(GTK_OBJECT(w_layout[current].drawing_area),
"expose_event", GINT_TO_POINTER(current));
static void expose_event(GtkWidget *widget, GdkEventExpose *event, gpointer
current_ptr)
{
gint current=GPOINTER_TO_INT(current_ptr);
gdk_draw_pixmap(widget->window,
widget->style->fg_gc[GTK_WIDGET_STATE(widget)],
w_layout[current].drawing_pixmap, 0, 0, 0, 0,
w_layout[current].width, w_layout[current].height);
}
gtk_signal_connect(GTK_OBJECT(w_layout[current].drawing_area),
"expose_event", GTK_SIGNAL_FUNC(expose_event), GINT_TO_POINTER(current));
When the gtk_signal_emit_by_name() is called, I get this warning:
Gtk-WARNING **: gtk_signal_collect_params(): invalid NULL pointer for return
argument type `gboolean'
Any ideas?
On a second similar-ish front, if I've got this:
gtk_signal_connect(GTK_OBJECT(w_layout[i].drawing_area),
"button_press_event", (GtkSignalFunc) button_press_event,
GINT_TO_POINTER(i));
to detect mouse clicks. Is there anyway I can tell if the shift button was
being held down at the same time as the click????
Ta folks!!
Rich
