Converting MOUSE_PARAMS cmd to MOUSE_EVENTS

[WhoAteDaCake]

Hi, I don't have much experience in C, so I'm a bit confused by how is the value converted to the enum, since I've seen values go higher than 4094, which is the maximum enum value. Is there some sort of bit shifting going on? Thanks!

cmd can be OR'ed with EVENT_SINKING and EVENT_HANDLED flags.

Thank you so much for that!

Is there a need to handle MOUSE_HIT_TEST in a special manner as well? After removing the mask, I am still sometimes getting 4095 as the value

There are two internal mouse related messages:

MOUSE_HIT_TEST = 0xFFE,
MOUSE_CHECK = 0xFFF, // 4095 decimal

MOUSE_HIT_TEST is used for non-rectangular elements - ones that have custom shape for example.
MOUSE_CHECK is used to setup cursor properly. For example after end of mouse wheel scroll, when mouse was not moved, engine sends this event to shifted content (setup cursor, check for mouse leave/enter, etc.)

Rule of the thumb: do not handle (skip) all messages you are not interested in.
