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.
