Detailed Description

Class that represents a target area for a widget or imagery component.

This is essentially a Rect built out of Dimension objects. Of note is that what would normally be the 'right' and 'bottom' edges may alternatively represent width and height depending upon what the assigned Dimension(s) represent.

Member Function Documentation

const String& CEGUI::ComponentArea::getAreaPropertySource ( ) const

Return the name of the property that will be used to determine the pixel area for this ComponentArea.

Returns
String object holding the name of a Propery.
Rectf CEGUI::ComponentArea::getPixelRect ( const Window wnd) const

Return a Rect describing the absolute pixel area represented by this ComponentArea.

Parameters
wndWindow object to be used when calculating final pixel area.
Returns
Rectf object describing the pixels area represented by this ComponentArea when using wnd as a reference for calculating the final pixel dimensions.
Rectf CEGUI::ComponentArea::getPixelRect ( const Window wnd,
const Rectf container 
) const

Return a Rectd describing the absolute pixel area represented by this ComponentArea.

Parameters
wndWindow object to be used when calculating final pixel area.
containerRect object to be used as a base or container when converting relative dimensions.
Returns
Rectf object describing the pixels area represented by this ComponentArea when using wnd and container as a reference for calculating the final pixel dimensions.
bool CEGUI::ComponentArea::isAreaFetchedFromNamedArea ( ) const

Return whether this ComponentArea fetches it's area via a named area defined.

Returns
  • true if the area comes via a named area defined in a WidgetLook.
  • false if the area is not sourced from a named area.
bool CEGUI::ComponentArea::isAreaFetchedFromProperty ( ) const

Return whether this ComponentArea fetches it's area via a property on the target window.

Returns
  • true if the area comes via a Propery.
  • false if the area is not sourced from a Property.
void CEGUI::ComponentArea::setAreaPropertySource ( const String property)

Set the name of the property that will be used to determine the pixel area for this ComponentArea.

Note
Calling this will replace any existing souce, such as a named area.
Parameters
propertyString object holding the name of a Propery. The property should access a URect type property.
void CEGUI::ComponentArea::writeXMLToStream ( XMLSerializer xml_stream) const

Writes an xml representation of this ComponentArea to out_stream.

Parameters
xml_streamXMLSerializer where xml data should be output.
