Constructor Detail

Area

public Area()

Area

public Area(java.lang.String coords)

Method Detail

getShape

public java.lang.String getShape()

Returns the shape of this area.

Default: null (means rectangle).

setShape

public void setShape(java.lang.String shape)
              throws WrongValueException

Sets the shape of this area.

Throws:

WrongValueException - if shape is not one of null, "rect", "rectangle", "circle", "circ", "polygon", and "poly".

getTabindexInteger

public java.lang.Integer getTabindexInteger()

Returns null if not set.

Returns:

the tab order of this component

Since:

8.0.2

setTabindex

public void setTabindex(java.lang.Integer tabindex)

Sets the tab order of this component. Removes the tabindex attribute if it's set to null.

Parameters:

tabindex -

getCoords

public java.lang.String getCoords()

Returns the coordination of this area.

setCoords

public void setCoords(java.lang.String coords)

Sets the coords of this area. Its content depends on getShape():

circle

coords="x,y,r"

polygon

coords="x1,y1,x2,y2,x3,y3..."
The polygon is automatically closed, so it is not necessary to repeat the first coordination.

rectangle

coords="x1,y1,x2,y2"

Note: (0, 0) is the upper-left corner.

getTooltiptext

public java.lang.String getTooltiptext()

Returns the text as the tooltip.

Default: null.

setTooltiptext

public void setTooltiptext(java.lang.String tooltiptext)

Sets the text as the tooltip.

isChildable

protected boolean isChildable()

Default: not childable.

Overrides:

isChildable in class AbstractComponent

beforeParentChanged

public void beforeParentChanged(Component parent)

Description copied from class: AbstractComponent

Default: If parent is null, execute the @Destroy method if any.

Specified by:

beforeParentChanged in interface ComponentCtrl

Overrides:

beforeParentChanged in class AbstractComponent

Parameters:

parent - the new parent. If null, it means detachment.

See Also:

ComponentCtrl.beforeParentChanged(org.zkoss.zk.ui.Component)

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException

Description copied from class: AbstractComponent

Called by (ComponentCtrl.redraw(java.io.Writer)) to render the properties, excluding the enclosing tag and children.

Default: it renders AbstractComponent.getId() if it was assigned, and event names if listened (and listed in AbstractComponent.getClientEvents()).

Note: it doesn't render AbstractComponent.getWidgetClass(), AbstractComponent.getUuid() and AbstractComponent.getMold(), which are caller's job.

Overrides:

renderProperties in class AbstractComponent

Throws:

java.io.IOException
