You should be able to override any commander method from inside the
LeoBridgeIntegController (BIC) class. This is tricky. Here is tested code:
class Test:
"""
An example patching a method in Leo's QTextMixin class.
The Test class represents the LeoBridgeIntegController class.
"""
def __init__(self, c):
self.commander = c
self.old_getSelectedText = c.frame.body.wrapper.getSelectedText
g.funcToMethod(
self.patched_getSelectedText,
c.frame.body.wrapper,
name='getSelectedText',
)
g.trace('Patched!')
def patched_getSelectedText(self):
"""
Call the original getSelectedText with g.app.inBridge = False.
"""
old_in_bridge = g.app.inBridge
try:
g.app.inBridge = False
func = self.old_getSelectedText
g.trace('Calling', func)
return func()
except Exception:
g.app.inBridge = old_in_bridge
g.es_exception()
return ''
Test(c)
To test:
- Run the script above.
- Create a node containing leading spaces. Select all the body text of that
node.
- Run the tabify command.
The output will be something like:
__init__ Patched!
patched_getSelectedText Calling <bound method QTextMixin.getSelectedText of
<QTextEditWrapper: 2633857821064 body>>
getSelectedText ===== QTextMixin <QTextEditWrapper: 2633857821064 body>
Notes:
- The patch should be applied to all commanders. Test by opening a new
outline.
- This is just a start. If you are going to wrap lots of methods it might
be useful to use __getattr__ in a generic wrapper.
Having said that, I never like to use __getattr__ :-)
HTH. I'm happy to help you on this project, so feel free to ask more
questions.
