deleteproperty - Remove custom property from COM object

Syntax

h.deleteproperty('propertyname')
deleteproperty(h, 'propertyname')

Description

h.deleteproperty('propertyname') deletes the property specified in the string propertyname from the custom properties belonging to object or interface h.

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

You can only delete properties created with the addproperty function.

COM functions are available on Microsoft Windows systems only.

Examples

Remove a custom property from 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
