Detailed Description

Class used for textual items in a list box.

Member Function Documentation

void CEGUI::ListboxTextItem::draw ( GeometryBuffer buffer,
const Rectf targetRect,
float  alpha,
const Rectf clipper 
) const
virtual

Draw the list box item in its current state.

Parameters
positionVecor2 object describing the upper-left corner of area that should be rendered in to for the draw operation.
alphaAlpha value to be used when rendering the item (between 0.0f and 1.0f).
clipperRect object describing the clipping rectangle for the draw operation.
Returns
Nothing.

Implements CEGUI::ListboxItem.

const Font* CEGUI::ListboxTextItem::getFont ( void  ) const

Return a pointer to the font being used by this ListboxTextItem.

This method will try a number of places to find a font to be used. If no font can be found, NULL is returned.

Returns
Font to be used for rendering this item
Sizef CEGUI::ListboxTextItem::getPixelSize ( void  ) const
virtual

Return the rendered pixel size of this list box item.

Returns
Size object describing the size of the list box item in pixels.

Implements CEGUI::ListboxItem.

ColourRect CEGUI::ListboxTextItem::getTextColours ( void  ) const
inline

Return the current colours used for text rendering.

Returns
ColourRect object describing the currently set colours
bool CEGUI::ListboxTextItem::handleFontRenderSizeChange ( const Font *const  font)
virtual

Perform any updates needed because the given font's render size has changed.

/note The base implementation just returns false.

Parameters
fontPointer to the Font whose render size has changed.
Returns
  • true if some action was taken.
  • false if no action was taken (i.e font is not used here).

Reimplemented from CEGUI::ListboxItem.

void CEGUI::ListboxTextItem::setFont ( Font font)

Set the font to be used by this ListboxTextItem.

Parameters
fontFont to be used for rendering this item
Returns
Nothing
void CEGUI::ListboxTextItem::setFont ( const String font_name)

Set the font to be used by this ListboxTextItem.

Parameters
font_nameString object containing the name of the Font to be used for rendering this item
Returns
Nothing
void CEGUI::ListboxTextItem::setText ( const String text)
virtual

set the text string for this list box item.

Note that even if the item does not render text, the text string can still be useful, since it is used for sorting list box items.

Parameters
textString object containing the text to set for the list box item.
Returns
Nothing.

Reimplemented from CEGUI::ListboxItem.

void CEGUI::ListboxTextItem::setTextColours ( const ColourRect cols)
inline

Set the colours used for text rendering.

Parameters
colsColourRect object describing the colours to be used.
Returns
Nothing.
void CEGUI::ListboxTextItem::setTextColours ( Colour  top_left_colour,
Colour  top_right_colour,
Colour  bottom_left_colour,
Colour  bottom_right_colour 
)

Set the colours used for text rendering.

Parameters
top_left_colourColour (as ARGB value) to be applied to the top-left corner of each text glyph rendered.
top_right_colourColour (as ARGB value) to be applied to the top-right corner of each text glyph rendered.
bottom_left_colourColour (as ARGB value) to be applied to the bottom-left corner of each text glyph rendered.
bottom_right_colourColour (as ARGB value) to be applied to the bottom-right corner of each text glyph rendered.
Returns
Nothing.
void CEGUI::ListboxTextItem::setTextColours ( Colour  col)
