Detailed Description

Dimension type that represents an Unified dimension. Implements BaseDim interface.


Constructor & Destructor Documentation

CEGUI::UnifiedDim::UnifiedDim ( const UDim value,
DimensionType  dim 
)

Constructor.

Parameters:
valueUDim holding the value to assign to this UnifiedDim.
dimDimensionType value indicating what this UnifiedDim is to represent. This is required because we need to know what part of the base Window that the UDim scale component is to operate against.

Member Function Documentation

BaseDim* CEGUI::UnifiedDim::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.

Gets the source dimension type for this WidgetDim.

Returns:
DimensionType value indicating which dimension should be used as the scale reference / base value when calculating the pixel value of this dimension.
float CEGUI::UnifiedDim::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::UnifiedDim::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.

Sets the source dimension type for this WidgetDim.

Parameters:
dimDimensionType value indicating which dimension should be used as the scale reference / base value when calculating the pixel value of this dimension.
