digitalmars.D.learn - How to rebind the default tkd GUI keybinds?

reply tastyminerals <tastyminerals gmail.com> writes:
Tk default keys are somewhat different from what we used to use 
for selecting, copying and pasting the text. So, any Tk based GUI 
app starts with writing the rebinding function for "ctrl+a", 
"ctrl+c", "ctrl+x" and "ctrl+v" keys, at least. I did it when 
writing TkInter based apps in Python. Today I am trying out tkd 
and want to do the same. However, it doesn't work :(

For example:

private void selectText(CommandArgs args) {
     this._clientId.selectText;
}

this._loginFrame = new Frame(2, ReliefStyle.groove);
this._clientId = new Entry(loginFrame).grid(1, 0);
this._clientId.bind("<Control-a>", &selectText);

It works if I change "<Control-a>" to "<Control-o>" for example.
But how do I overwrite the actual "<Control-a>" key in tkd?

So, this is even tricky in Python TkInter but possible.
In tkd this is not possible unfortunately.

You could try directly calling 
[bindtags](https://www.tcl.tk/man/tcl8.4/TkCmd/bindtags.htm) with 
_tk.eval. Modifying and extending tkd is easy from my experience 
where I had added support for additional image formats. (After 
blundering about on how to get tcl/tk to work, lol.)

So, there is a way. It just needs substantial time investment :)
Thanks for point it out.
