[XaraXtreme-dev] Text tool shortcuts

[Martin Wuerthner <lists@xxxxxxxxxxxxxxx>]

I have had a look at text tool shortcuts, which currently do not work 
and I have found the following:

 (1) A keypress like "arrow left" moves the caret AND is handled 
     by the hotkeys system, too, so it causes a nudge operation 
     as well. So, if you move the caret left in text and go to 
     the Edit menu, it says "Undo nudge".

 (2) Ctrl+letter shortcuts (e.g., Ctrl-W) are not working at all.

 (3) Even if Ctrl-W (swap case) was correctly recognized it would 
     not work because an underlying function to swap case is not 
     yet implemented.

(2) is caused by wxWidgets setting the virtual key of Ctrl-letter 
combinations to the control code (i.e., 1 for Ctrl-A) instead of the 
uppercase letter, which is what the code expects. I have fixed that in 
the Keypress constructor. I also have a fix for (3).

I found the problem that causes (1) but I am wondering how to best 
deal with it. The problem is that the application gets THREE key 
messages for a keypress like "arrow left":

      IsChar() IsRelease()
1st    FALSE     FALSE
2nd    TRUE      FALSE
3rd    FALSE     TRUE

The text tool responds to presses with IsChar=TRUE and IsRelease=FALSE 
while the hotkey system responds to presses with IsChar=FALSE and 
IsRelease=FALSE. So, the text tool ignores the 1st message, which the 
hotkey system happily processes. Then, the text tool processes the 
second message. Surely, something is wrong there. What is the point in 
having two "press" messages for each keypress? Is this deliberate?
