Detailed Description

The Gls CTL (Complex Text Layout) Text Box.

On certain platforms, the text layout library is unavailable, and complex text rendering in the runtime will be missing.

To account for this, the GlsCTLTextBox will 'Fallback' to being treated as a GlsTextBox. In those cases, certain GlsCTLTextBox functions will not have no effect.

Member Enumeration Documentation

enum EllipsizeMode_t

The ellipsize mode types.

enum TextDirection_t

The text direction types. TEXT_DIRECTION_LTR - Use Left to Right as the base direction for rendering text. TEXT_DIRECTION_RTL - Use Right to Left as the base direction for rendering text. TEXT_DIRECTION_AUTOMATIC - Determine the base direction for rendering text from the first strongly directioned character. TEXT_DIRECTION_AUTO_BY_LINE - Determine the base direction for rendering text for each individual EOL-seperated line in the text string.

enum VerticalAlignment_t

The vertical alignment types.

Returns: A new object, identical to the original, except for the instance name

Reimplemented from GLPolygon.

virtual void CopyGeometry ( DisplayObject * src )

Parameters

src	The object to copy geometry from

Reimplemented from GlsText.

virtual

Copies the attributes except for geometry attributes from one object to another. Used by the undo mechanism to undo most attribute change operations.

Parameters

Draws this object on the current display frame (_parent member).

Reimplemented from GLPolygon.

virtual void DrawText ( )

protectedvirtual

Draws the polygons that make up the characters.

virtual EllipsizeMode_t EllipsizeMode ( )

virtual

Gets the type of automatic ellipsize if the text does not fit in the boundary.

Returns: The type of automatic ellipsize if the text does not fit in the boundary.

Note: In CTL Fallback mode, returns ELLIPSIZE_MODE_NONE.

virtual void EllipsizeMode ( const EllipsizeMode_t ellipsizeMode )

virtual

Sets the type of automatic ellipsize if the text does not fit in the boundary.

Parameters

[in] ellipsizeMode The type of automatic ellipsize if the text does not fit in the boundary.

Note: In CTL Fallback mode, has no effect.

virtual InterfaceListType* GetCppInterfaceDescription ( InterfaceListType * addToThisList = NULL )

virtual

Get the details of the Cpp Interface The actual interface is exposed in compiled code.

Parameters

addToThisList If not NULL this list will be added to then returned. If NULL a new list will be created.

Returns: A templated list. The caller must call the corresponding free method to safely free the memory.

Reimplemented from GlsText.

virtual void GetCppInterfaceDescriptionFree ( InterfaceListType * array )

virtual

Frees the memory allocated by a previous call to GetCppInterfaceDescription

Parameters

array Memory allocated by a previous call to GetCppInterfaceDescription

Reimplemented from GlsText.

virtual unsigned int GetGlyphCount ( )

virtual

Gets the number of glyphs in the layout.

Returns: The number of glyphs in the layout.

Note: In CTL Fallback mode, returns 0.

virtual GlyphMetrics GetGlyphMetrics ( const unsigned int glyphIndex )

virtual

Gets the glyph metrics for the given glyph index.

Parameters

[in] glyphIndex The index of the glyph in the layout line to get the glyph metrics for.

Returns: The glyph metrics for the given glyph index.

Note: In CTL Fallback mode, returns a default GlyphMetrics struct.

virtual unsigned int GetLineCount ( )

virtual

Gets the number of lines in the layout.

Returns: The number of lines in the layout.

Note: In CTL Fallback mode, returns 0.

virtual void PreDraw	(	const OpenGLMatrices &	current,
		Culler &	culler
	)

virtual

Traverses the hierarchy calculating the _modelMatrix, _projMatrix, _viewMatrix as needed.

Parameters

current	Current matrices inherited from parent
culler	Object that possibly marks this object for culling

Reimplemented from DisplayObject.

virtual void Rebuild ( )

virtual

Rebuilds this text box layout. This may be an expensive call, so it should only be called when a property changes.

virtual void RecalcVertices ( )

protectedvirtual

Rebuilds the vertices of the text box.

bool RequiresFontFile ( ) const

inlinevirtual

See also: GlsText

Reimplemented from GlsText.

virtual void Scale	(	float	px,
		float	py,
		float	pz,
		Vertex *	anchor,
		int	handleBar
	)

virtual

Scales the object, either the handleBar, or the Anchor is used to translate the object, not both. Anchor takes presidence, if it is set HandleBar is ignored. The footprint is different from the 2D scale so the compiler can destinguish the two.

Parameters

px	Value of the percentage of scale in x-axis
py	Value of the percentage of scale in y-axis
pz	Value of the percentage of scale in z-axis
anchor	Anchor from which to scale object relative to
handleBar	Vertex that is being dragged

Reimplemented from DisplayObject.

virtual void SetAltHeight ( float height )

virtual

Set height used to render the text. If the height of the vertices is smaller than this height, the text will be truncated. If the value is 0.0, the text will be rendered to the full height of the vertices

Note: In CTL Fallback mode, has no effect.

virtual void SetAltWidth ( float width )

virtual

Set width used to render the text. If the width of the vertices is smaller than this width, the text will be truncated. If the value is 0.0, the text will be rendered to the full width of the vertices

Note: In CTL Fallback mode, has no effect.

virtual void SetAvailableAttributes ( unsigned int value )

virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters

value A bitfield specifying which types of attributes to make available.

See also: AvailableAttributesEnum

Reimplemented from GlsText.

virtual void SetLayoutAutoDir ( bool )
