CodeEdit

Inherits: TextEdit < Control < CanvasItem < Node < Object

A multiline text editor designed for editing code.

Description

CodeEdit is a specialized TextEdit designed for editing plain text code files. It has many features commonly found in code editors such as line numbers, line folding, code completion, indent management, and string/comment management.

Note: Regardless of locale, CodeEdit will by default always use left-to-right text direction to correctly display source code.

Methods

Theme Properties

Signals

breakpoint_toggled ( int line )

Emitted when a breakpoint is added or removed from a line. If the line is moved via backspace a removed is emitted at the old line.

code_completion_requested ( )

Emitted when the user requests code completion.

symbol_lookup ( String symbol, int line, int column )

Emitted when the user has clicked on a valid symbol.

symbol_validate ( String symbol )

Emitted when the user hovers over a symbol. The symbol should be validated and responded to, by calling set_symbol_lookup_word_as_valid.

Enumerations

enum CodeCompletionKind:

CodeCompletionKind KIND_CLASS = 0

Marks the option as a class.

CodeCompletionKind KIND_FUNCTION = 1

Marks the option as a function.

CodeCompletionKind KIND_SIGNAL = 2

Marks the option as a Godot signal.

CodeCompletionKind KIND_VARIABLE = 3

Marks the option as a variable.

CodeCompletionKind KIND_MEMBER = 4

Marks the option as a member.

CodeCompletionKind KIND_ENUM = 5

Marks the option as an enum entry.

CodeCompletionKind KIND_CONSTANT = 6

Marks the option as a constant.

CodeCompletionKind KIND_NODE_PATH = 7

Marks the option as a Godot node path.

CodeCompletionKind KIND_FILE_PATH = 8

Marks the option as a file path.

CodeCompletionKind KIND_PLAIN_TEXT = 9

Marks the option as unclassified or plain text.

enum CodeCompletionLocation:

CodeCompletionLocation LOCATION_LOCAL = 0

The option is local to the location of the code completion query - e.g. a local variable. Subsequent value of location represent options from the outer class, the exact value represent how far they are (in terms of inner classes).

CodeCompletionLocation LOCATION_PARENT_MASK = 256

The option is from the containing class or a parent class, relative to the location of the code completion query. Perform a bitwise OR with the class depth (e.g. 0 for the local class, 1 for the parent, 2 for the grandparent, etc) to store the depth of an option in the class or a parent class.

CodeCompletionLocation LOCATION_OTHER_USER_CODE = 512

The option is from user code which is not local and not in a derived class (e.g. Autoload Singletons).

CodeCompletionLocation LOCATION_OTHER = 1024

The option is from other engine code, not covered by the other enum constants - e.g. built-in classes.
