public class Completion
extends GObject

Main Completion Object.

The completion system helps the user when they writes some text, such as words, command names, functions, and suchlike. Proposals can be shown, to complete the text the user is writing. Each proposal can contain an additional piece of information (for example documentation), that is displayed when the "Details" button is clicked.

Proposals are created via a CompletionProvider. There can be for example a provider to complete words (see CompletionWords), another provider for the completion of function names, etc. To add a provider, call addProvider(org.gnome.gtksourceview.CompletionProvider).

The CompletionProposal interface represents a proposal.

If a proposal contains extra information (see CompletionColumn.DETAILS), it will be displayed in a supplemental details window, which appears when the "Details" button is clicked.

Each View object is associated with a Completion instance. This instance can be obtained with View.getCompletion(). The View class contains also the View::show-completion signal.

A same CompletionProvider object can be used for several GtkSourceCompletion's.

Constructor Details

Completion

public Completion(MemorySegment address)

Create a Completion proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Completion

public Completion()

Creates a new Completion.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the Completion class

Returns:

the GType

asParent

protected Completion 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

fuzzyHighlight

public static @Nullable AttrList fuzzyHighlight(String haystack,
 String casefoldQuery)

This will add <b> tags around matched characters in haystack based on casefoldQuery.

Parameters:

haystack - the string to be highlighted

casefoldQuery - the typed-text used to highlight haystack

Returns:

a PangoAttrList or null

fuzzyMatch

public static boolean fuzzyMatch(@Nullable String haystack,
 String casefoldNeedle,
 @Nullable Out<Integer> priority)

This helper function can do a fuzzy match for you giving a haystack and casefolded needle.

Casefold your needle using GLib.utf8Casefold(java.lang.String, long) before running the query.

Score will be set with the score of the match upon success. Otherwise, it will be set to zero.

Parameters:

haystack - the string to be searched.

casefoldNeedle - A g_utf8_casefold() version of the needle.

priority - An optional location for the score of the match

Returns:

true if haystack matched casefoldNeedle, otherwise false.

addProvider

public void addProvider(CompletionProvider provider)

Adds a CompletionProvider to the list of providers to be queried for completion results.

Parameters:

provider - a GtkSourceCompletionProvider

blockInteractive

public void blockInteractive()

getBuffer

public Buffer getBuffer()

Gets the connected View's Buffer

Returns:

A GtkSourceBuffer

getPageSize

public int getPageSize()

getView
