events (COM)

Return a list of events that the control can trigger

Syntax

• events(h)
  

Arguments

h
   Handle for a MATLAB COM control object.

Description

Returns a structure array containing all events, both registered and unregistered, known to the control, and the function prototype used when calling the event handler routine. For each array element, the structure field is the event name and the contents of that field is the function prototype for that event's handler.

Note    The send function is identical to events, but send will be made obsolete in a future release.

Examples

Create an mwsamp control and list all events:

• f = figure ('pos', [100 200 200 200]);
  h = actxcontrol ('mwsamp.mwsampctrl.2', [0 0 200 200], f);
  
  events(h)
     Click = void Click()
     DblClick = void DblClick()
     MouseDown = void MouseDown(int16 Button, int16 Shift, 
        Variant x, Variant y)
  

Or assign the output to a variable and get one field of the returned structure:

• ev = events(h);
  
  ev.MouseDown
  ans =
  void MouseDown(int16 Button, int16 Shift, Variant x, Variant y)
