Provides a convenient wrapper for normalized keyboard navigation. KeyNav allows you to bind navigation keys to function calls that will get called when the keys are pressed, providing an easy way to implement custom navigation schemes for any UI component.
The following are all of the possible keys that can be implemented: enter, space, left, right, up, down, tab, esc, pageUp, pageDown, del, backspace, home, end. Usage:
var nav = new Ext.util.KeyNav("my-element", {
"left" : function(e){
this.moveLeft(e.ctrlKey);
},
"right" : function(e){
this.moveRight(e.ctrlKey);
},
"enter" : function(e){
this.save();
},
scope : this
});
The method to call on the Ext.EventObject after this KeyNav intercepts a key. Valid values are Ext.EventObject.stopEvent, Ext.EventObject.preventDefault and Ext.EventObject.stopPropagation (defaults to 'stopEvent')
True to disable this KeyNav instance (defaults to false)
True to disable this KeyNav instance (defaults to false)
Handle the keydown event instead of keypress (defaults to false). KeyNav automatically does this for IE since IE does not propagate special keys on keypress, but setting this to true will force other browsers to also handle keydown instead of keypress.
Destroy this KeyNav (this is the same as calling disable).
Destroy this KeyNav (this is the same as calling disable).
True to remove the element associated with this KeyNav.
Determines the event to bind to listen for keys. Depends on the forceKeyDown setting, as well as the useKeyDown option on the EventManager.
The type of event to listen for.
