Class Ext.Resizable

Package:Ext
Defined In:Resizable.js
Class:Resizable
Extends:Observable

Applies drag handles to an element to make it resizable. The drag handles are inserted into the element and positioned absolute. Some elements, such as a textarea or image, don't support this. To overcome that, you can wrap the textarea in a div and set 'resizeChild' to true (or to the id of the element), or set wrap:true in your config and the element will be wrapped for you automatically.

Here is the list of valid resize handles:

Value   Description
------  -------------------
 'n'     north
 's'     south
 'e'     east
 'w'     west
 'nw'    northwest
 'sw'    southwest
 'se'    southeast
 'ne'    northeast
 'all'   all

Here's an example showing the creation of a typical Resizable:

var resizer = new Ext.Resizable('element-id', {
    handles: 'all',
    minWidth: 200,
    minHeight: 100,
    maxWidth: 500,
    maxHeight: 400,
    pinned: true
});
resizer.on('resize', myHandler);

To hide a particular handle, set its display to none in CSS, or through script:
resizer.east.setDisplayed(false);
