Run AFL by (shift/alt)+mouse scroll or keystrokes

[gaborkuti]

[Repeated question from AB forum, sorry about that]

1) Is it possible to catch the mouse scroll using GetCursorMouseButtons()? It's working great for _pressing_ the buttons but not for the scroll itself.



2) How are key strokes registered?



I have created a pane only containing RequestTimedRefresh(0.1) and a couple of GetAsyncKeyState() calls. E.g:

if( GetAsyncKeyState( vk_LShift ) < 0 ) { _TRACE("HERE Up2"); DecreaseScaleOffset(); }



This helps keeping the PC load in bay (0-3% for AB, otherwise it shot up to the 40% load area just for that process).



Yet, registering the keypresses still is subpar performance: only every 2nd/3rd press actually invokes the supposed AFL code and even then the lag is unbearable for a GUI. It also looks like keystrokes get executed many 10 seconds after the fact.



a) Is there a way to make processing of keypresses snappy?

b) Is it possible to override existing keystrokes? (Like alt-left, alt-right)?

1) You could via storing GetCursorXPosition( 1 ) and GetCursorYPosition( 1 ) by using "visible bar range"-check and check for first visble bar change and using static variables.

2a) Don't understand

2b) Do you mean via Tools - Customize - Keyboard?

Or do you mean

altleft = GetAsyncKeyState( 18 ) < 0 && GetAsyncKeyState( 37 ) < 0;

if( altleft )
   Say( "Alt, Left keys have been pressed" );

Just tested my thought myself via small code and it works.
