Proposed patch for gtkmain.c (3.55 KB, patch)
2004-04-24 18:03 UTC, Chris Sherlock 		none Details | Review

Description Chris Sherlock 2004-04-24 18:02:40 UTC 
gtkmain.c functions that generate this warning:

load_module - happens because g_module_symbol is not passed a gpointer address.
Dealt with this by creating a new gpointer variable pmodinit_func, then copied
the address of the function pointer modinit_func into it. pmodinit_func is then
passed to g_module_symbol.

rewrite_event_for_grabs - gdk_window_get_user_data expects 2nd parameter to be a
gpointer*, instead is getting a GtkWidget*. Did much the same thing as with
load_module fix.

gtk_get_event_widget - same reason as for rewrite_event_for_grabs, it calls
gdk_window_get_user_data and passes it a GtkWidget* as second parameter. Same fix.

Comment 4 Björn Lindqvist 2008-03-27 22:07:27 UTC 
Resolving as obsolete, patch doesn't apply anymore and the relevant code has disappeared from gtkmain.c since the patch was written.
