How do I disable Zoom and Pan in the post action callback?

When I try to set the zoom or pan objects to off in the post action callback, MATLAB generates an error. The post action callback is structured in the following way:

For zoom:

function myzoompostcallback(obj,evd)

hZ = zoom(obj);

%turn zoom off

set(hZ,'Enable','off');

This callback creates the following error:

 

Warning: An error occurred during the mode callback.

  For pan:

function mypanpostcallback(obj,evd)

hP = pan(obj);

%turn pan off
set(hP,'Enable','off');

This callback creates the following error:

Warning: An error occurred during the mode callback.

To enable the ability to turn off pan or zoom in the post action callback, you must set the "ModeHandle" 's "Blocking" property to false. This feature is undocumented and is not even visible when the property 'hideundocumented' is set to 'off'.

For "zoom": Use the following code in the post action callback to turn off the zoom using the set function:

 

function myzoompostcallback(obj,evd)

%obtain zoom object from figure
hZ = zoom(obj);

%turn blocking off to allow setting the zoom state (true by default)
hM = hZ.ModeHandle;
set(hM,'Blocking',false);

%turn zoom off
set(hZ,'Enable','off');

Use the following code in the post action callback to turn off the zoom using dot notation:

function myzoompostcallback(obj,evd)

hZ = zoom(obj);

hZ.ModeHandles.Blocking = false;
hZ.Enable = 'off';

 

For "pan":

Use the following code in the post action callback to turn off the pan using the set function:

 

function mypanpostcallback(obj,evd)

%obtain pan object from figure
hP = pan(obj);

%turn blocking off to allow setting the pan state (true by default)
hM = hP.ModeHandle;
set(hM,'Blocking',false);

%turn pan off
set(hP,'Enable','off');

Use the following code in the post action callback to turn off the pan using dot notation:

 

function mypanpostcallback(obj,evd)

hP = pan(obj);

hP.ModeHandles.Blocking = false;
hP.Enable = 'off';
