Property Descriptions¶

HorizontalAlignment alignment = 0

void set_horizontal_alignment ( HorizontalAlignment value )
HorizontalAlignment get_horizontal_alignment ( )

Sets text alignment within the line as if the line was horizontal.

Direction direction = 0

void set_direction ( Direction value )
Direction get_direction ( )

Text writing direction.

BitField<JustificationFlag> flags = 3

void set_flags ( BitField<JustificationFlag> value )
BitField<JustificationFlag> get_flags ( )

Line alignment rules. For more info see TextServer.

Orientation orientation = 0

void set_orientation ( Orientation value )
Orientation get_orientation ( )

Text orientation.

bool preserve_control = false

void set_preserve_control ( bool value )
bool get_preserve_control ( )

If set to true text will display control characters.

bool preserve_invalid = true

void set_preserve_invalid ( bool value )
bool get_preserve_invalid ( )

If set to true text will display invalid characters.

OverrunBehavior text_overrun_behavior = 3

void set_text_overrun_behavior ( OverrunBehavior value )
OverrunBehavior get_text_overrun_behavior ( )

Sets the clipping behavior when the text exceeds the text line's set width. See OverrunBehavior for a description of all modes.

float width = -1.0

void set_width ( float value )
float get_width ( )

Text line width.

Method Descriptions¶

bool add_object ( Variant key, Vector2 size, InlineAlignment inline_align=5, int length=1, float baseline=0.0 )

Adds inline object to the text buffer, key must be unique. In the text, object is represented as length object replacement characters.

bool add_string ( String text, Font font, int font_size, String language="", Variant meta=null )

Adds text span and font to draw it.

void clear ( )

Clears text line (removes text and inline objects).

void draw ( RID canvas, Vector2 pos, Color color=Color(1, 1, 1, 1) ) const

Draw text into a canvas item at a given position, with color. pos specifies the top left corner of the bounding box.

void draw_outline ( RID canvas, Vector2 pos, int outline_size=1, Color color=Color(1, 1, 1, 1) ) const

Draw text into a canvas item at a given position, with color. pos specifies the top left corner of the bounding box.

float get_line_ascent ( ) const

Returns the text ascent (number of pixels above the baseline for horizontal layout or to the left of baseline for vertical).

float get_line_descent ( ) const

Returns the text descent (number of pixels below the baseline for horizontal layout or to the right of baseline for vertical).

float get_line_underline_position ( ) const

Returns pixel offset of the underline below the baseline.

float get_line_underline_thickness ( ) const

Returns thickness of the underline.

float get_line_width ( ) const

Returns width (for horizontal layout) or height (for vertical) of the text.

Rect2 get_object_rect ( Variant key ) const

Returns bounding rectangle of the inline object.

Array get_objects ( ) const

Returns array of inline objects.

RID get_rid ( ) const

Returns TextServer buffer RID.

Vector2 get_size ( ) const

Returns size of the bounding box of the text.

int hit_test ( float coords ) const

Returns caret character offset at the specified pixel offset at the baseline. This function always returns a valid position.

bool resize_object ( Variant key, Vector2 size, InlineAlignment inline_align=5, float baseline=0.0 )

Sets new size and alignment of embedded object.

void set_bidi_override ( Array override )

Overrides BiDi for the structured text.

Override ranges should cover full source text without overlaps. BiDi algorithm will be used on each range separately.

void tab_align ( PackedFloat32Array tab_stops )

Aligns text to the given tab-stops.
