tf = h.isevent('eventname') returns logical 1 (true) if event_name is an event recognized by COM object h. Otherwise, returns logical 0 (false). The event_name argument is not case sensitive.

tf = isevent(h, 'eventname') is an alternate syntax.

COM functions are available on Microsoft Windows systems only.

Examples

Test events in a MATLAB sample control object:

Create an instance of the mwsamp control and test DblClick:

f = figure ('position', [100 200 200 200]);
h = actxcontrol ('mwsamp.mwsampctrl.2', [0 0 200 200], f);
h.isevent('DblClick')

MATLAB displays true, indicating DblClick is an event.

Try the same test onRedraw:
```
h.isevent('Redraw')
```
MATLAB displays false, indicating Redraw is not an event; it is a method.

Test events in a Microsoft Excel workbook object:

Create a Workbook object wb:

myApp = actxserver('Excel.Application');
wbs = myApp.Workbooks;
wb = wbs.Add;

Test Activate:
```
wb.isevent('Activate')
```
MATLAB displays true, indicating Activate is an event.
Test Save:
```
wb.isevent('Save')
```
MATLAB displays false, indicating Save is not an event; it is a method.
