* UI Layout Callback: pseudoClose
|
|
*
|
|
* Prevent panes from closing completely so that an iframes/objects
|
|
* does not reload/refresh when pane 'opens' again.
|
|
* This callback preventing a normal 'close' and instead resizes the pane as small as possible
|
|
*
|
|
* SAMPLE:
|
|
* pseudoClose: { selector: "#myObject" }
|
|
* south__onclose: $.layout.callbacks.pseudoClose
|
|
*

* Version: 1.1 - 2012-03-10
