Member Function Documentation

BaseDim * CEGUI::BaseDim::clone  )  const
 

Create an exact copy of the specialised class 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.

Returns:
BaseDim object pointer

virtual BaseDim* CEGUI::BaseDim::clone_impl  )  const [protected, pure virtual]
 

Implementataion method to return a clone of this sub-class of BaseDim. This method should not attempt to clone the mathematical operator or operand; theis is handled automatically by BaseDim.

Implemented in CEGUI::AbsoluteDim, CEGUI::ImageDim, CEGUI::WidgetDim, CEGUI::UnifiedDim, CEGUI::FontDim, and CEGUI::PropertyDim.

DimensionOperator CEGUI::BaseDim::getDimensionOperator  )  const
 

Return the DimensionOperator set for this BaseDim based object.

Returns:
One of the DimensionOperator enumerated values representing a mathematical operation to be performed upon this BaseDim using the set operand.

Definition at line 128 of file CEGUIFalDimensions.cpp.

const BaseDim * CEGUI::BaseDim::getOperand  )  const
 

Return a pointer to the BaseDim set to be used as the other operand.

Returns:
Pointer to the BaseDim object.

Definition at line 138 of file CEGUIFalDimensions.cpp.

float CEGUI::BaseDim::getValue const Window wnd,
const Rect container
const
 

Return a value that represents this dimension as absolute pixels.

Parameters:
wnd Window 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).
container Rect 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.

float CEGUI::BaseDim::getValue const Window wnd  )  const
 

Return a value that represents this dimension as absolute pixels.

Parameters:

Returns:
float value which represents, in pixels, the same value as this BaseDim.
