Monitoring mouse events

6 posts in this topic

I've put together an events monitor that writes to a single array called $currentEvent.

Right now, $currentEvent has two elements, the name of the event and the time it fired. Add 2 more elements to return the X/Y data behind the event, or roll your own. I leave it undone because it's more extensible in this state.

There are 14 Core events being monitored. Each event is unique and is captured consistently. To modify the speed of double clicks, change the value of $doubleClickTime, currently 400 ms.

  • Left Click
  • Left Double Click
  • Left Drag/Drop
  • Left/Right Click
  • Left/Right Drag/Drop
  • Right Click
  • Right Double Click
  • Right Drag/Drop
  • Middle Click
  • Middle Double Click
  • Middle/Left Drag/Drop
  • Middle/Right Drag/Drop
  • MouseWheel Up
  • MouseWheel Down
Each event gets triggered, and some events subsume others.

To use it yourself: Just take out the GUI stuff, leave in #include <WinAPI.au3> , the Register Callback code, and the functions.

The array $currentEvent is Global and can be accessed anywhere in your scripts, so long as you don't overwrite it. This array is being updated in realtime, whenever a new mouse event is being detected. Using a buffer, or compensating for a potential mid-function change in value, is probably a good idea.

Now its time for generic rendering and animation, yay. :)

Very good! Thanks, now i really can see that wheel scrolling up and down events can be captured easily (for my _MouseSetOnEvent() UDF) :)

Global $doubleClickTime = 400 

Can be replaced by:

Global $doubleClickTime = DllCall("user32.dll", "uint", "GetDoubleClickTime")
$doubleClickTime = $doubleClickTime[0]

Whats the bottom number being displayed represent? Time between events in nano seconds? Current date?
