TextEdit

继承： Control < CanvasItem < Node < Object

派生： CodeEdit

A multiline text editor.

描述

A multiline text editor. It also has limited facilities for editing code, such as syntax highlighting support. For more advanced facilities for editing code, see CodeEdit.

Note: Most viewport, caret, and edit methods contain a caret_index argument for caret_multiple support. The argument should be one of the following: -1 for all carets, 0 for the main caret, or greater than 0 for secondary carets in the order they were created.

Note: When holding down Alt, the vertical scroll wheel will scroll 5 times as fast as it would normally do. This also works in the Godot script editor.

已弃用： No longer necessary since methods now adjust carets themselves.

This method does nothing.

void adjust_viewport_to_caret ( caret_index: int = 0 )

Multicaret edits can be used to edit text at multiple carets and delay merging the carets until the end, so the caret indexes aren't affected immediately. begin_multicaret_edit and end_multicaret_edit can be nested, and the merge will happen at the last end_multicaret_edit.

Example usage:

    begin_complex_operation()
    begin_multicaret_edit()
    for i in range(get_caret_count()):
        if multicaret_edit_ignore_caret(i):

    public override void _Ready()
    {

int caret_width = 1

The caret's width in pixels. Greater values can be used to improve accessibility by ensuring the caret is easily visible, or to ensure consistency with a large font size. If set to 0 or lower, the caret width is automatically set to 1 pixel and multiplied by the display scaling factor.

int line_spacing = 4

Sets the spacing between the lines.

int outline_size = 0

The size of the text outline.

Note: If using a font with FontFile.multichannel_signed_distance_field enabled, its FontFile.msdf_pixel_range must be set to at least twice the value of outline_size for outline rendering to look correct. Otherwise, the outline may appear to be cut off earlier than intended.

Font font

Sets the default Font.

int font_size

Sets default font size.

Texture2D space

Sets a custom Texture2D for space text characters.

Texture2D tab

Sets a custom Texture2D for tab text characters.

StyleBox focus

Sets the StyleBox when in focus. The focus StyleBox is displayed over the base StyleBox, so a partially transparent StyleBox should be used to ensure the base StyleBox remains visible. A StyleBox that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a StyleBoxEmpty resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.

StyleBox normal

Sets the StyleBox of this TextEdit.

StyleBox read_only

Sets the StyleBox of this TextEdit when editable is disabled.
