Currently, Mi-Forms detects different input modalities and has them work as expected. A mouse and keyboard input can enter text, a stylus can ink, and a touch enabled device can use touch to do either without changing modes. 

One limitation is that mouse inking is only accepted on freeform fields (like Signature fields) by default.

However, there are times where you need to test inking capabilities, but are developing with a machine that only has a mouse. You can still use the mouse to test inking by setting the following property in the Mi-Forms Component.

 

_component.MouseStylusEmulation = True

 

This will allow the mouse to act like a stylus with inking capabilities on the form.
