TIL: Inform-PE and _MOUSE*

[grymmjack]

I had some weird issues using _MOUSE* stuff in QB64PE within InForm-PE and I suspected that it was because my mouse input loop was hijacking the events away from InForm-PE, and it turns out I was right.

@a740g explained that I should not create my own mouse input loop and instead use these wrappers inside of InFPE (which are as of yet undocumented):

You should not call the QB64 _MOUSE* call directly. That will mess up InFrom mouse handling. 😁

Instead use the following in readonly mode:
__UI_HasInput
__UI_MouseWheel
__UI_MouseButton1
__UI_MouseButton2
__UI_MouseLeft
__UI_MouseTop

By readonly mode, @a740g means that these are variables we can read from, example:
__UI_HasInput
