Bind Tab Key on Text Editor

[PatLechevallier]

Re,

I did a monkey patch.

def create_text_editor(self, r = 0, c = 0, text = None, state = "normal", see = True, set_data_ref_on_destroy = False, binding = None):
. . .
elif binding is None and set_data_ref_on_destroy:
        self.text_editor.textedit.bind("<Return>", lambda x: self.get_text_editor_value((r, c, "Return")))
        self.text_editor.textedit.bind("<FocusOut>", lambda x: self.get_text_editor_value((r, c, "FocusOut")))
        self.text_editor.textedit.bind("<Escape>", lambda x: self.get_text_editor_value((r, c, "Escape")))
        self.text_editor.textedit.bind("<Tab>", lambda x: self.get_text_editor_value((r, c, "Return"), move_down=False, move_right=True))
. . .

def bind_text_editor_destroy(self, binding, r, c):
    self.text_editor.textedit.bind("<Return>", lambda x: binding((r, c, "Return")))
    self.text_editor.textedit.bind("<FocusOut>", lambda x: binding((r, c, "FocusOut")))
    self.text_editor.textedit.bind("<Escape>", lambda x: binding((r, c, "Escape")))
    self.text_editor.textedit.bind("<Tab>", lambda x: binding((r, c, "Return")))
    self.text_editor.textedit.focus_set()

def get_text_editor_value(self, destroy_tup = None, r = None, c = None, set_data_ref_on_destroy = True, event = None, destroy = True, move_down = True, move_right=False, redraw = True, recreate = True):
. . .
if move_right:
            if r is None and c is None and destroy_tup:
                r, c = destroy_tup[0], destroy_tup[1]
            currently_selected = self.currently_selected()
            if r is not None and c is not None:
                if (
                    currently_selected and
                    r == currently_selected[0] and
                    c == currently_selected[1] and
                    (self.single_selection_enabled or self.toggle_selection_enabled)
                    ):
                    self.select_cell(r , c+1 if c<len(self.col_positions) - 2 else c)
                    self.see(r, c+1 if c < len(self.col_positions) - 2 else c, keep_xscroll = True, bottom_right_corner = True, check_cell_visibility = True)
. . .

Plus I added <Tab> in the bind of arrowkeys.
It's 90% the same behavior as in excel. It does job.

It should be added in 4.9.7 but try it out and let me know if it's not working correctly

Regarding

In a more generic way, can we just add the possibility of binding other keys on the text editor?

I added the below code in version 4.9.7

def bind_key_text_editor(self, key, function):
    self.MT.text_editor_user_bound_keys[key] = function

def unbind_key_text_editor(self, key):
    if key == "all":
        for key in self.MT.text_editor_user_bound_keys:
            try:
                self.MT.text_editor.textedit.unbind(key)
            except:
                pass
        self.MT.text_editor_user_bound_keys = {}
    else:
        if key in self.MT.text_editor_user_bound_keys:
            del self.MT.text_editor_user_bound_keys[key]
        try:
            self.MT.text_editor.textedit.unbind(key)
        except:
            pass

It's not perfect though because you can't really bind keys to the text widgets actual functions, I might add this functionality later, but I can't give you a time frame sorry

[PatLechevallier]

The functionality for the event <Tab> is working fine. 👍
No worries, it's not a priority.
