public class GutterLines
extends GObject

Collected information about visible lines.

The GtkSourceGutterLines object is used to collect information about visible lines.

Use this from your GutterRenderer::query-data to collect the necessary information on visible lines. Doing so reduces the number of passes through the text btree allowing GtkSourceView to reach more frames-per-second while performing kinetic scrolling.

Constructor Details

GutterLines

public GutterLines(MemorySegment address)

Create a GutterLines proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the GutterLines class

Returns:

the GType

asParent

protected GutterLines 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 GObject

addClass

public void addClass(int line,
 String name)

Adds the class name to line.

name will be converted to a GLib.Quark as part of this process. A faster version of this function is available via addQclass(int, org.gnome.glib.Quark) for situations where the GLib.Quark is known ahead of time.

Parameters:

line - a line number starting from zero

name - a class name

addQclass

public void addQclass(int line,
 Quark qname)

Adds the class denoted by qname to line.

You may check if a line has qname by calling hasQclass(int, org.gnome.glib.Quark).

You can remove qname by calling removeQclass(int, org.gnome.glib.Quark).

Parameters:

line - a line number starting from zero

qname - a class name as a GQuark

getBuffer

public TextBuffer getBuffer()

Gets the TextBuffer that the GtkSourceGutterLines represents.

Returns:

a GtkTextBuffer

getFirst

public int getFirst()

Gets the line number (starting from 0) for the first line that is user visible.

Returns:

a line number starting from 0

getIterAtLine

public void getIterAtLine(TextIter iter,
 int line)

Gets a GtkTextIter for the current buffer at line

Parameters:

iter - a location for a GtkTextIter

line - the line number

getLast

public int getLast()

Gets the line number (starting from 0) for the last line that is user visible.

Returns:

a line number starting from 0

getLineYrange

public void getLineYrange(int line,
 GutterRendererAlignmentMode mode,
 Out<Integer> y,
 Out<Integer> height)

Gets the Y range for a line based on mode.

The value for y is relative to the renderers widget coordinates.

Parameters:

line - a line number starting from zero

mode - a GtkSourceGutterRendererAlignmentMode

y - a location for the Y position in widget coordinates

height - the line height based on mode

getView

public TextView getView()

Gets the TextView that the GtkSourceGutterLines represents.

Returns:

a GtkTextView

hasAnyClass

public boolean hasAnyClass(int line)

Checks to see if the line has any GQuark classes set. This can be used to help renderer implementations avoid work if nothing has been set on the class.

Parameters:

line - a line contained within this GutterLines

Returns:

true if any quark was set for the line

hasClass

public boolean hasClass(int line,
 String name)

Checks to see if addClass(int, java.lang.String) was called with the name for line.

A faster version of this function is provided via hasQclass(int, org.gnome.glib.Quark) for situations where the quark is known ahead of time.

Parameters:

line - a line number starting from zero

name - a class name that may be converted, to a GQuark

Returns:

true if line contains name

hasQclass

public boolean hasQclass(int line,
 Quark qname)

Checks to see if addQclass(int, org.gnome.glib.Quark) was called with the quark denoted by qname for line.

Parameters:

line - a line number starting from zero

qname - a GQuark containing the class name

Returns:

true if line contains qname

isCursor

public boolean isCursor(int line)

Checks to see if line contains the insertion cursor.

Parameters:

line - a line number starting from zero

Returns:

true if the insertion cursor is on line

isPrelit

public boolean isPrelit(int line)

Checks to see if line is marked as prelit. Generally, this means the mouse pointer is over the line within the gutter.

Parameters:

line - a line number starting from zero

Returns:

true if the line is prelit

isSelected

public boolean isSelected(int line)

Checks to see if the view had a selection and if that selection overlaps line in some way.

Parameters:

line - a line number starting from zero

Returns:

true if the line contains a selection

removeClass

public void removeClass(int line,
 String name)

Removes the class matching name from line.

A faster version of this function is available via removeQclass(int, org.gnome.glib.Quark) for situations where the GQuark is known ahead of time.

Parameters:

line - a line number starting from zero

name - a class name

removeQclass

public void removeQclass(int line,
 Quark qname)

Reverses a call to addQclass(int, org.gnome.glib.Quark) by removing the GLib.Quark matching qname.

Parameters:

line - a line number starting from zero

qname - a GQuark to remove from line

builder

public static GutterLines.Builder<? extends GutterLines.Builder> builder()

A GutterLines.Builder object constructs a GutterLines with the specified properties. Use the various set...() methods to set properties, and finish construction with GutterLines.Builder.build().
