PgLayoutLine

A PangoLayoutLine represents one of the lines resulting from laying out a paragraph via PangoLayout.

PangoLayoutLine structures are obtained by calling [method@Pango.Layout.get_line] and are only valid until the text, attributes, or settings of the parent PangoLayout are modified.

Functions

getExtents void getExtents(PangoRectangle inkRect, PangoRectangle logicalRect): Computes the logical and ink extents of a layout line.
getHeight void getHeight(int height): Computes the height of the line, as the maximum of the heights of fonts used in this line.
getLength int getLength(): Returns the length of the line, in bytes.
getPgLayoutLineStruct PangoLayoutLine* getPgLayoutLineStruct(bool transferOwnership): Get the main Gtk struct
getPixelExtents void getPixelExtents(PangoRectangle inkRect, PangoRectangle logicalRect): Computes the logical and ink extents of @layout_line in device units.
getResolvedDirection PangoDirection getResolvedDirection(): Returns the resolved direction of the line.
getStartIndex int getStartIndex(): Returns the start index of the line, as byte index into the text of the layout.
getStruct void* getStruct(): the main Gtk struct as a void*
getXRanges void getXRanges(int startIndex, int endIndex, int[] ranges): Gets a list of visual ranges corresponding to a given logical range.
indexToX void indexToX(int index, bool trailing, int xPos): Converts an index within a line to a X position.
isParagraphStart bool isParagraphStart(): Returns whether this is the first line of the paragraph.
ref_ PgLayoutLine ref_(): Increase the reference count of a PangoLayoutLine by one.
unref void unref(): Decrease the reference count of a PangoLayoutLine by one.
xToIndex bool xToIndex(int xPos, int index, int trailing): Converts from x offset to the byte index of the corresponding character within the text of the layout.
