addproperty

Add custom property to COM object

Syntax

h.addproperty('propertyname')
addproperty(h,'propertyname')

Description

h.addproperty('propertyname') adds the custom property specified in the string propertyname to the object or interface h. Use the COM set function to assign a value to the property.

addproperty(h,'propertyname') is an alternate syntax.

COM functions are available on Microsoft® Windows® systems only.

Examples

Add a custom property to an instance of the MATLAB® sample control:

  1. Create an instance of the control:

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

    MATLAB displays its properties:

         Label: 'Label'
        Radius: 20
    
  2. Add a custom property named Position and assign a value:

    h.addproperty('Position');
    h.Position = [200 120];
    h.get
    

    MATLAB displays (in part):

           Label: 'Label'
          Radius: 20
        Position: [200 120]
  3. Delete the custom property Position:

    h.deleteproperty('Position');
    h.get
    

    MATLAB displays the original list of properties:

         Label: 'Label'
        Radius: 20
