ej.microui.util.EventHandler	getEventHandler() Gets the event handler.
int	getHeight() Gets the height of this renderable.
int	getWidth() Gets the width of this renderable.
int	getX() Gets the x coordinate of this renderable, relative to its parent.
int	getY() Gets the y coordinate of this renderable, relative to its parent.
boolean	handleEvent(int event) Called by the system when an event occurred. Pointer related events are sent to the pointed renderable.
void	hideNotify() This method is called as soon as the renderable is hidden.
boolean	isShown() Gets whether or not this renderable is shown on a display.
void	render(ej.microui.display.GraphicsContext g) Renders the renderable on the given graphics context.
void	repaint() Requests a repaint of this renderable.
void	repaint(int x, int y, int width, int height) Requests a repaint of a zone of this renderable.
void	setEventHandler(ej.microui.util.EventHandler eventHandler) Sets the event handler.
void	showNotify() This method is called as soon as the renderable is visible.

Method Detail

getX

int getX()

Gets the x coordinate of this renderable, relative to its parent.

Returns:

the x coordinate

getY

int getY()

Gets the y coordinate of this renderable, relative to its parent.

Returns:

the y coordinate

getWidth

int getWidth()

Gets the width of this renderable.

Returns:

the width

getHeight

int getHeight()

Gets the height of this renderable.

Returns:

the height

isShown

boolean isShown()

Gets whether or not this renderable is shown on a display.

Returns:

true if the renderable is shown, false otherwise

showNotify

void showNotify()

This method is called as soon as the renderable is visible.

hideNotify

void hideNotify()

This method is called as soon as the renderable is hidden.

repaint

void repaint()

Requests a repaint of this renderable.

repaint

void repaint(int x,
             int y,
             int width,
             int height)

Requests a repaint of a zone of this renderable.

Parameters:

x - the relative x coordinate of the area to repaint

y - the relative y coordinate of the area to repaint

width - the width of the area to repaint

height - the height of the area to repaint

render

void render(ej.microui.display.GraphicsContext g)

Renders the renderable on the given graphics context.

Parameters:

g - the graphics context to be used to draw the renderable.

Since:

2.0

setEventHandler

void setEventHandler(ej.microui.util.EventHandler eventHandler)

Sets the event handler.

Parameters:

eventHandler - the event handler to set.

Since:

2.0

See Also:

handleEvent(int)

getEventHandler

ej.microui.util.EventHandler getEventHandler()

Gets the event handler.

Returns:

the event handler.

Since:

2.0

See Also:

handleEvent(int)

handleEvent

boolean handleEvent(int event)

Called by the system when an event occurred.
Pointer related events are sent to the pointed renderable. Other events are sent to the focus owner of the active panel and progressing up its hierarchy while not consumed until the desktop.

Parameters:

event - the event to handle

Returns:

true if the renderable has consumed the event, false otherwise
