Re: help on gtk

[Richard Boaz <riboaz xs4all nl>]

hi,

gtk_combo_set_popdown_strings() is deprecated and should not be used  
in newly written code.  you should replace both the combo box  
creation and population with the following:

gtk_combo_box_new_text()

followed by:

gtk_combo_box_insert_text() for each of the strings in your items array.

furthermore, why are you using g_object*() functions to retrieve  
values held by widgets?

there are gtk*() specific routines for what you are trying to  
achieve, namely:

gtk_entry_get_text(), and
gtk_comb_box_get_active_text()

use these and your problems will magically disappear!

cheers,

richard
