Catching ESCAPE Key

wxPython Users
1

Hi,

    I want to do something when user hits ESCAPE key from a frame with
a panel. I tried accelerator table like this:

I have a button with an ID = wx.ID_CANCEL

frame.SetAcceleratorTable(wx.AcceleratorTable([
            (wx.ACCEL_NORMAL, wx.WXK_ESCAPE, wx.ID_CANCEL),
        ]))

It didn't work. Then I tried catching key down event of the panel.
That didn't work either.

Oops. I hit send button.
...
It's on windows 2.8.0.1

Accelerators send EVT_MENU events, so just having a button with that ID is not enough. You also need to bind a handler for EVT_MENU with that ID.

Thank you Robin. I did it now and it works. But on windows ESCAPE key
doesn't work. Other keys like F1, F2 works.

It depends on the context, as ESC may be snatched for dialogs, etc. You can try getting it with the EVT_CHAR_HOOK event.

Thanks Robin, worked smoothly. If you didn't say that there was
EVT_CHAR_HOOK I wouldn't know it. They probably forgot to write it in
the docs.

One way to do it under Windows:

i = win32api.GetAsyncKeyState(win32con.VK_ESCAPE)
if i < 0:
     print "escape!"
