Constructor Details

TextNode

public TextNode(MemorySegment address)

Create a TextNode proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

TextNode

public TextNode(Font font,
 GlyphString glyphs,
 RGBA color,
 Point offset)

Creates a render node that renders the given glyphs.

Note that color may not be used if the font contains color glyphs.

Parameters:

font - the PangoFont containing the glyphs

glyphs - the PangoGlyphString to render

color - the foreground color to render with

offset - offset of the baseline

Method Details

getType

public static @Nullable Type getType()

Get the GType of the TextNode class

Returns:

the GType

asParent

protected TextNode asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class RenderNode

getColor

public RGBA getColor()

Retrieves the color used by the text node.

The value returned by this function will not be correct if the render node was created for a non-sRGB color.

Returns:

the text color

getFont

public Font getFont()

Returns the font used by the text node.

Returns:

the font

getGlyphs

public GlyphInfo[] getGlyphs()

Retrieves the glyph information in the node.

Returns:

the glyph information

getNumGlyphs

public int getNumGlyphs()

Retrieves the number of glyphs in the text node.

Returns:

the number of glyphs

getOffset

public Point getOffset()

Retrieves the offset applied to the text.

Returns:

a point with the horizontal and vertical offsets

hasColorGlyphs

public boolean hasColorGlyphs()

Checks whether the text this TextNode has color glyphs.

Returns:

true if the text node has color glyphs
