Member Function Documentation

◆ draw()

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

position	Vecor2 object describing the upper-left corner of area that should be rendered in to for the draw operation.
alpha	Alpha value to be used when rendering the item (between 0.0f and 1.0f).
clipper	Rect object describing the clipping rectangle for the draw operation.

Returns: Nothing.

Implements CEGUI::ListboxItem.

◆ getFont()

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

◆ getPixelSize()

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.

◆ getTextColours()

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

inline

Return the current colours used for text rendering.

Returns: ColourRect object describing the currently set colours

◆ handleFontRenderSizeChange()

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

font	Pointer 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.

◆ setFont() [1/2]

void CEGUI::ListboxTextItem::setFont ( const String & font_name )

Set the font to be used by this ListboxTextItem.

Parameters

font_name String object containing the name of the Font to be used for rendering this item

Returns: Nothing

◆ setFont() [2/2]

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

Set the font to be used by this ListboxTextItem.

Parameters

font	Font to be used for rendering this item

Returns: Nothing

◆ setText()

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

text	String object containing the text to set for the list box item.

Returns: Nothing.

Reimplemented from CEGUI::ListboxItem.

◆ setTextColours() [1/3]

void CEGUI::ListboxTextItem::setTextColours ( Colour col )

inline

Set the colours used for text rendering.

Parameters

col	colour value to be used when rendering.

Returns: Nothing.

References setTextColours().

◆ setTextColours() [2/3]

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_colour	Colour (as ARGB value) to be applied to the top-left corner of each text glyph rendered.
top_right_colour	Colour (as ARGB value) to be applied to the top-right corner of each text glyph rendered.
bottom_left_colour	Colour (as ARGB value) to be applied to the bottom-left corner of each text glyph rendered.
bottom_right_colour	Colour (as ARGB value) to be applied to the bottom-right corner of each text glyph rendered.

Returns: Nothing.

◆ setTextColours() [3/3]

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

inline

Set the colours used for text rendering.

Parameters

cols	ColourRect object describing the colours to be used.

Returns: Nothing.

◆ setTextParsingEnabled()

void CEGUI::ListboxTextItem::setTextParsingEnabled ( const bool enable )

Set whether the the ListboxTextItem will have it's text parsed via the BasicRenderedStringParser or not.

Parameters

enable

true if the ListboxTextItem text will be parsed.
false if the ListboxTextItem text will be used verbatim.
