For most of the ActiveX controls there is no automatic way of determining if it supports keyboard input to disable the 3ds Max keyboard accelerators.
A MAXScript system global called "enableAccelerators" can be set to false whenever an ActiveX control gets focus so that the user can type in the controls.
Here is a sample that can be handy to enable/disable keyboard accelarators:
Example:
rollout rAccelState "State"
(
checkButton accelState "Test"
on rAccelState open do
(
accelState.text = if (enableAccelerators) then "Enabled" else "Disabled"
accelState.checked = enableAccelerators
)
on accelState changed state do
(
enableAccelerators = state
accelState.text = if (enableAccelerators) then "Enabled" else "Disabled"
)
)
nf = newRolloutFloater "" 100 100
addRollout rAccelState nf
Note:
There is no real way of determing when an activeX control got focus and when it lost it and automatically disable/enable Max's accelarators. It's upto the script writer's discretion to find a clever way to disable them. There is a "on StatusTextChange ..." event handler to disable the accelerators, but it is not fail-proof.
on ax StatusTextChange txt do enableAccelerators = false
