Hi,
After IRC talk about modals, i try to expose the issue here for the records.

Actually,
some addons use transform.translate as snap provider.
There is also an attempt to allow on screen navigation while running transform modals.

Current modals does not allow events to bubble up in the stack
make it impossible to handle user interaction in caller when modals are stacked.

Archipack modal stack sample:


Manipulate modal
draw manipulators
___________________

User hover and drag an arrow handle


transform.translate
issue: events are stuck here
manipulate can't properly
handle interaction

hackaround :
callback in a draw handler
______________________________

Proposed solutions:

1 Being able to enforce PASS_THROUGH on transform.translate (any modal)
instead of RUNNING_MODAL.
Keep returning FINISHED as it.
So calling operator may properly handle events too.

This may also enable a native way to navigate on screen
even with modal running.

2 being able to add a handler like the draw one

with a callback done when modal get an event

@StephenLeger - committed return {'RUNNING_MODAL', 'PASS_THROUGH'} for events you want to pass through to other operators, while keeping your manipulator running.
