Hello, Every body I put a GtkImage into a GtkScrolledWindow. If the image is very large, I intend to make it scrolling down by press the "PageDown" key. But I don't know the correct way to implement this. I tried the following code (in Pascal, PageUp case): >>>>>> adjust:=gtk_scrolled_window_get_vadjustment(PGtkScrolledWindow(ImageWindow_sw)); with adjust^ do begin pinpoint:=value; if pinpoint<upper then pinpoint:=value+upper; if pinpoint>upper then pinpoint:=upper; gtk_adjustment_set_value(adjust,pinpoint); gtk_adjustment_value_changed(adjust); gtk_adjustment_changed(adjust); end; <<<<<<
But unfortunately, the image will become a black board. _______________________________________________ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
