c - Is it possible to disable, fade or make a button inside a dialog unclickable in GTK? -


i have dialog this:

gtkwidget *dialog = gtk_dialog_new_with_buttons("spell checking", null, 0,                                                 gtk_stock_ok,                                                 gtk_response_accept,                                                 gtk_stock_add,                                                 gtk_response_apply,                                                 gtk_stock_cancel,                                                 gtk_response_reject,                                                 null);

after adding other necessary elements it'll this:

spell check dialog

what want disable ok button if list of correct words empty.

of course, there workarounds creating dialog:

  • with ok when list not empty
  • without otherwise

nevertheless, i know if can disable/fade buttoon , how.

gtk widgets have property sensitive, when it's set false, widget grayed out, i.e. user couldn't interact it. there's a function purpose

void gtk_widget_set_sensitive (gtkwidget *widget,                           gboolean sensitive);

also try set directly, mybutton->sensitive = false.
