Detailed Description

Dimension type that represents the result of an operation performed on two other dimension values. Implements BaseDim interface.

Member Function Documentation

BaseDim* CEGUI::OperatorDim::clone ( ) const
virtual

Create an exact copy of the specialised object and return it as a pointer to a BaseDim object.

Since the system needs to be able to copy objects derived from BaseDim, but only has knowledge of the BaseDim interface, this clone method is provided to prevent slicing issues.

Implements CEGUI::BaseDim.

float CEGUI::OperatorDim::getValue ( const Window wnd) const
virtual

Return a value that represents this dimension as absolute pixels.

Parameters
wndWindow object that may be used by the specialised class to aid in calculating the final value.
Returns
float value which represents, in pixels, the same value as this BaseDim.

Implements CEGUI::BaseDim.

float CEGUI::OperatorDim::getValue ( const Window wnd,
const Rectf container 
) const
virtual

Return a value that represents this dimension as absolute pixels.

Parameters
wndWindow object that may be used by the specialised class to aid in calculating the final value (typically would be used to obtain window/widget dimensions).
containerRect object which describes an area to be considered as the base area when calculating the final value. Basically this means that relative values are calculated from the dimensions of this Rect.
Returns
float value which represents, in pixels, the same value as this BaseDim.

Implements CEGUI::BaseDim.

void CEGUI::OperatorDim::writeXMLToStream ( XMLSerializer xml_stream) const
protectedvirtual

Writes an xml representation of this BaseDim to out_stream.

Parameters
xml_streamStream where xml data should be output.
