pango.layout_line

Module for [LayoutLine] class

class LayoutLine

Types 1

classLayoutLine : gobject.boxed.Boxed

A [pango.layout_line.LayoutLine] represents one of the lines resulting from laying out a paragraph via [pango.layout.Layout].

[pango.layout_line.LayoutLine] structures are obtained by calling [pango.layout.Layout.getLine] and are only valid until the text, attributes, or settings of the parent [pango.layout.Layout] are modified.

Methods

GType _getGType()
GType _gType() @property
LayoutLine self()Returns `this`, for use in `with` statements.
pango.layout.Layout layout() @propertyGet `layout` field. Returns: the layout this line belongs to, might be null
void layout(pango.layout.Layout propval) @propertySet `layout` field. Params: propval = the layout this line belongs to, might be null
int startIndex() @propertyGet `startIndex` field. Returns: start of line as byte index into layout->text
void startIndex(int propval) @propertySet `startIndex` field. Params: propval = start of line as byte index into layout->text
int length() @propertyGet `length` field. Returns: length of line in bytes
void length(int propval) @propertySet `length` field. Params: propval = length of line in bytes
uint isParagraphStart() @propertyGet `isParagraphStart` field. Returns: #TRUE if this is the first line of the paragraph
void isParagraphStart(uint propval) @propertySet `isParagraphStart` field. Params: propval = #TRUE if this is the first line of the paragraph
uint resolvedDir() @propertyGet `resolvedDir` field. Returns: #Resolved PangoDirection of line
void resolvedDir(uint propval) @propertySet `resolvedDir` field. Params: propval = #Resolved PangoDirection of line
void getExtents(out pango.types.Rectangle inkRect, out pango.types.Rectangle logicalRect)Computes the logical and ink extents of a layout line.
void getHeight(out int height)Computes the height of the line, as the maximum of the heights of fonts used in this line.
int getLength()Returns the length of the line, in bytes. Returns: the length of the line
void getPixelExtents(out pango.types.Rectangle inkRect, out pango.types.Rectangle logicalRect)Computes the logical and ink extents of layout_line in device units.
pango.types.Direction getResolvedDirection()Returns the resolved direction of the line. Returns: the resolved direction of the line
int getStartIndex()Returns the start index of the line, as byte index into the text of the layout. Returns: the start index of the line
void getXRanges(int startIndex, int endIndex, out int[] ranges)Gets a list of visual ranges corresponding to a given logical range.
void indexToX(int index, bool trailing, out int xPos)Converts an index within a line to a X position.
bool xToIndex(int xPos, out int index, out int trailing)Converts from x offset to the byte index of the corresponding character within the text of the layout.
