Detailed Description

Dimension type that represents some metric of a Font. Implements BaseDim interface.

Constructor & Destructor Documentation

CEGUI::FontDim::FontDim ( const String name,
const String font,
const String text,
FontMetricType  metric,
float  padding = 0 
)

Constructor.

Parameters
nameString holding the name suffix of the window to be accessed to obtain the font and / or text strings to be used when these items are not explicitly given.
fontString holding the name of the font to use for this dimension. If the string is empty, the font assigned to the window passed to getValue will be used.
textString holding the text to be measured for horizontal extent. If this is empty, the text from the window passed to getValue will be used.
metricOne of the FontMetricType values indicating what we should represent.
paddingconstant pixel padding value to be added.

Member Function Documentation

BaseDim* CEGUI::FontDim::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::FontDim::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::FontDim::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.
