Public Member Functions inherited from PowerUI.HtmlTagHandler
void	RequestLayout ()
	Requests the renderer handling this element to layout next update. More...

virtual bool	Junk ()

virtual void	OnMouseMove (UIEvent moveEvent)
	Called on the focused element when the mouse is moved. More...

virtual void	OnChildrenLoaded ()
	Called when the elements kids are fully loaded. More...

Public Member Functions inherited from Wrench.TagHandler
virtual bool	SelfClosing ()
	Returns true if this tag has no kids and closes itself. For example <input type='text' />. Note that this method exists to make that final slash essentially optional. More...

virtual void	OnTagLoaded ()
	Called when the tag is instanced and the element plus its attributes and kids have been fully parsed. More...

Public Attributes
string	Value
	The value text for this input. More...

Element	Cursor
	This is the cursor element. More...

int	CursorIndex
	The current location of the cursor. More...

bool	LocateCursor
	True if the cursor should be located after the next update. More...

int	MaxLength =int.MaxValue
	The maximum length of text in this box. More...

Public Attributes inherited from PowerUI.HtmlTagHandler
bool	IsIsolated
	True if this element is isolated from style changes by its parent (e.g. used by iframes). More...

Element	Element
	The element this tag handler is attached to. More...

bool	IgnoreClick
	True if the element should ignore all clicks. More...

bool	IsFocusable
	True if this tag is focusable. More...

bool	IgnoreSelfClick
	Set this to true if this element should ignore clicks on itself, but not its kids (e.g. html or body). More...

Public Attributes inherited from Wrench.TagHandler
int	Priority
	If you define a tag handler with tags which already exist, this priority allows your tag to override the existing one optionally. All system tags have a priority of zero. More...

string	TagExtension
	This is applied to every derivative of this tag handler. This enables tags to be grouped by file they are handling. e.g. "ui" extension and tag name "div" would become "ui-div" internally. More...

Private Member Functions
void	LocateCursorNow ()
	Positions the cursor immediately. More...

bool	AtEnd (MLLexer lexer)
	Checks if the given lexer has reached the end of the inline textarea content. More...
