isevent

Determine whether input is COM object event

Syntax

tf = isevent(c,eventname)

Description

tf = isevent(c,eventname) returns logical 1 (true) if eventname is an event recognized by the COM object. Otherwise, it returns logical 0 (false).

Examples

Test for mwsamp Events

Test if DblClick is an event in the MATLAB^® sample control. MATLAB displays true, indicating DblClick is an event.

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);
isevent(h,'DblClick')

Test Redraw. MATLAB displays false, indicating Redraw is not an event; it is a method.

isevent(h,'Redraw')
