GtkLabel reset and GtkTextView max length
- I've a NULL gtklabel. Upon the occurrence of an开发者_StackOverflow中文版 event, I set a text in this label (with gtk_label_set_text). How can I reset the gtklabel after the event (reset to NULL)?
- How can I set the max length (characters) of a GtkTextView?
- What's the easiest way to set the distance from the margin of a widget in a GtkTable?
- As I understand from code, you can just use
gtk_label_set_text (label, NULL). If that fails for any reason (e.g. earlier version doesn't allowNULL), just replace it with"". - You cannot, directly. Simplest non-direct approach would be to connect to "insert-text" on the view's
GtkTextBufferandg_signal_stop_emission_by_name()when you don't want the insertion to actually happen. Never did this, so it's just what I'd try, no guarantees it will really work. - Not quite sure what you mean. You could try using a
GtkAlignmentaround your widget and set padding on it — may or may not be what you want.
