Actually, there was a crasher due to a recent blunder. Here is the
log for rev 1290, committed several hours ago:
QQQ
Completed first draft of code to bypass "dangerous" keys:
- Set module-level safe_mode "constant" to True.
- Created isDangerous method.
- Bypass Leo bindings if isDangerous(tkKey,ch) returns True.
QQQ
The log didn't mention the bug fix: I thought nobody had noticed, but
I was wrong :-)
So I think we are *very* close to being able to eat our own dog food.
The isDangerous method is intended to return True for
Return,Tab,Backspace and all arrow keys except Alt-arrow keys. I
didn't really test it, so it may not work as intended. It would
probably be better just to list the keys that are not to be allowed.
Anyway, it's a start, and it's self contained.
I also added a 'safe_mode' module-level "constant", which enabled the
isDangerous processing. To allow all Leo bindings just set safe_mode
= False.
Key handling seems a bit zippier in safe_mode. More importantly, the
typical keys that require (but don't get) byte offsets in the Leo
implementation get sent straight to Qt. Safe mode is a nice blend of
prototyping and full Leo implementation.
Still to do:
- Issue warnings in leoQtBody if methods get executed that could
return dubious results.
- Draw only visible nodes in leoQtTree.redraw_now.
So *maybe* we are ready to eat our own dog food. Check it out, but
use caution.
