Re: Newbie needs help: gtk_entry's stopped accepting key stroke entires
FIXED!! I hope the moderator leaves this on the forum: It was not
Google-able ... just in case someone else pulls a bone-head move like I did.
This code was working as a key event handler:
static int key_pressed3(GtkWidget* w, GdkEventKey* event, gpointer data) {
if (event-keyval == 65293)
actionOptions(w, data);
return true;
}
... later ... in the signal area:
gtk_signal_connect(GTK_OBJECT(dialog), key_press_event,
GTK_SIGNAL_FUNC(key_pressed3), dialog);
It turns out that this is either not needed, depreciated, or just plain
wrong. I'm sure that I borrowed this from someone 4 years ago. Some things
definitely changed with GTK over the last 4 years. Commenting out the
signal_connect line restored my keyboard keypress events for all of my
gtk_entry textboxes. It would still be cool if someone vastly more
knowledgable than me could add a note to this thread explaining why this
code worked 4 years ago, what it did 4 years ago, and why it doesn't work
now.
Later -

any of them

boxes or part of the text that is set into a field

changed values are pulled later (e.g., a box has a '1' in it; you
drag-and-drop a '0' out of another field to that field, a '10' comes back
when the field is checked with a 'gtk_entry_get_text'
-- gtk_entry_set_editable (discontinued) and gtk_editable_set_editable
have no affect (true or false)
-- Fields seem to respond normally to other settings (e.g., they can be
enabled/disabled, made invisible/visible, etc.)
-- Other widgets in the window work perfectly: checkboxes, radiobuttons,
regular buttons
Everything about these fields is normal, except that no characters appear
when pressing any keys on the keyboard.
The field setup is pretty straightforward:
GtkWidget *CreateTextEntry(const char *s) {
GtkWidget *w = gtk_entry_new();
gtk_entry_set_text(GTK_ENTRY(w), s);
//gtk_entry_set_editable(GTK_ENTRY(w), TRUE); //discontinued
gtk_editable_set_editable(GTK_EDITABLE(w), TRUE);
return w;
}
Am I missing some sort of new gtk_entry signal/keyboard hookup?
Is there something wrong with my old code for this window's events that
would let everything else work but not keyboard entries?
gtk_widget_show_all(dialog);
gtk_main();
gtk_widget_destroy(dialog);
while (gtk_events_pending()) gtk_main_iteration();
return gGTKAnswer;
Or, is this going to be some sort of library/dll/compiler settings issue?
I'm STUCK!

Your code returns TRUE from the event handler. This stops signal
emission and keeps other handlers from being invoked. Check the
documentation of GtkWidget::key-press-event (or any other event signal
handler).
BTW, this would have been more appropriate to ask on gtk-list or
gtk-app-devel-list as this list is about development of GTK+, not about
development using GTK+.
