Ctrl + U: Delete text from the caret position to the beginning of the line
Ctrl + K: Delete text from the caret position to the end of the line
Ctrl + A: Select all text
Up Arrow/Down Arrow: Move the caret to the beginning/end of the line
On macOS, some extra keyboard shortcuts are available:
Cmd + F: Same as Right Arrow, move the caret one character right
Cmd + B: Same as Left Arrow, move the caret one character left
Cmd + P: Same as Up Arrow, move the caret to the previous line
Cmd + N: Same as Down Arrow, move the caret to the next line
Cmd + D: Same as Delete, delete the character on the right side of caret

Property Descriptions¶
HorizontalAlignment alignment = 0 🔗
void set_horizontal_alignment(value: HorizontalAlignment)
HorizontalAlignment get_horizontal_alignment()
Text alignment as defined in the HorizontalAlignment enum.
If true, makes the caret blink.
float caret_blink_interval = 0.65 🔗
The interval at which the caret blinks (in seconds).
The caret's column position inside the LineEdit. When set, the text may scroll to accommodate it.
bool caret_force_displayed = false 🔗
If true, the LineEdit will always show the caret, even if focus is lost.
bool caret_mid_grapheme = false 🔗
Allow moving caret, selecting and removing the individual composite character components.
Note: Backspace is always removing individual composite character components.
bool clear_button_enabled = false 🔗
If true, the LineEdit will show a clear button if text is not empty, which can be used to clear the text quickly.
If true, the context menu will appear when right-clicked.
bool deselect_on_focus_loss_enabled = true 🔗
If true, the selected text will be deselected when focus is lost.
bool drag_and_drop_selection_enabled = true 🔗
If true, allow drag and drop of selected text.
bool draw_control_chars = false 🔗
If true, control characters are displayed.
If false, existing text cannot be modified and new text cannot be added.
bool expand_to_text_length = false 🔗
If true, the LineEdit width will increase to stay longer than the text. It will not compress if the text is shortened.
If true, the LineEdit doesn't display decoration.
Language code used for line-breaking and text shaping algorithms. If left empty, current locale is used instead.
Maximum number of characters that can be entered inside the LineEdit. If 0, there is no limit.
When a limit is defined, characters that would exceed max_length are truncated. This happens both for existing text contents when setting the max length, or for new text inserted in the LineEdit, including pasting. If any input text is truncated, the text_change_rejected signal is emitted with the truncated substring as parameter.
Example:
text = "Hello world"
max_length = 5
# `text` becomes "Hello".
max_length = 10
text += " goodbye"
# `text` becomes "Hello good".
# `text_change_rejected` is emitted with "bye" as parameter.
Text = "Hello world";
MaxLength = 5;
// `Text` becomes "Hello".
MaxLength = 10;
Text += " goodbye";
// `Text` becomes "Hello good".
// `text_change_rejected` is emitted with "bye" as parameter.
bool middle_mouse_paste_enabled = true 🔗

Method Descriptions¶
void clear() 🔗
Erases the LineEdit's text.
void delete_char_at_caret() 🔗
Deletes one character at the caret's current position (equivalent to pressing Delete).
void delete_text(from_column: int, to_column: int) 🔗
Deletes a section of the text going from position from_column to to_column. Both parameters should be within the text's length.
void deselect() 🔗
Clears the current selection.
Returns the PopupMenu of this LineEdit. By default, this menu is displayed when right-clicking on the LineEdit.
You can add custom menu items or remove standard ones. Make sure your IDs don't conflict with the standard ones (see MenuItems). For example:
func _ready():
var menu = get_menu()
# Remove all items after "Redo".
menu.item_count = menu.get_item_index(MENU_REDO) + 1
# Add custom items.
menu.add_separator()
menu.add_item("Insert Date", MENU_MAX + 1)
# Connect callback.
menu.id_pressed.connect(_on_item_pressed)
func _on_item_pressed(id):
if id == MENU_MAX + 1:
insert_text_at_caret(Time.get_date_string_from_system())
public override void _Ready()
{
var menu = GetMenu();
// Remove all items after "Redo".
menu.ItemCount = menu.GetItemIndex(LineEdit.MenuItems.Redo) + 1;
// Add custom items.
menu.AddSeparator();
menu.AddItem("Insert Date", LineEdit.MenuItems.Max + 1);
// Add event handler.
menu.IdPressed += OnItemPressed;
}
public void OnItemPressed(int id)
{
if (id == LineEdit.MenuItems.Max + 1)
{
InsertTextAtCaret(Time.GetDateStringFromSystem());
}
}
Warning: This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their Window.visible property.
float get_scroll_offset() const 🔗
Returns the scroll offset due to caret_column, as a number of characters.
Returns the text inside the selection.
int get_selection_from_column() const 🔗
Returns the selection begin column.
int get_selection_to_column() const 🔗
Returns the selection end column.
Returns true if the user has selected text.
void insert_text_at_caret(text: String) 🔗
Inserts text at the caret. If the resulting value is longer than max_length, nothing happens.
Returns whether the menu is visible. Use this instead of get_menu().visible to improve performance (so the creation of the menu is avoided).
Executes a given action as defined in the MenuItems enum.
void select(from: int = 0, to: int = -1) 🔗
Selects characters inside LineEdit between from and to. By default, from is at the beginning and to at the end.
text = "Welcome"
select() # Will select "Welcome".
select(4) # Will select "ome".
select(2, 5) # Will select "lco".
Text = "Welcome";
Select(); // Will select "Welcome".
Select(4); // Will select "ome".
Select(2, 5); // Will select "lco".
void select_all() 🔗
Selects the whole String.
Theme Property Descriptions¶
Color caret_color = Color(0.95, 0.95, 0.95, 1) 🔗
Color of the LineEdit's caret (text cursor). This can be set to a fully transparent color to hide the caret entirely.
Color clear_button_color = Color(0.875, 0.875, 0.875, 1) 🔗
Color used as default tint for the clear button.
Color clear_button_color_pressed = Color(1, 1, 1, 1) 🔗
Color used for the clear button when it's pressed.
Color font_color = Color(0.875, 0.875, 0.875, 1) 🔗
Default font color.
Color font_outline_color = Color(0, 0, 0, 1) 🔗
The tint of text outline of the LineEdit.
Color font_placeholder_color = Color(0.875, 0.875, 0.875, 0.6) 🔗
Font color for placeholder_text.
Color font_selected_color = Color(1, 1, 1, 1) 🔗
Font color for selected text (inside the selection rectangle).
Color font_uneditable_color = Color(0.875, 0.875, 0.875, 0.5) 🔗
Font color when editing is disabled.
Color selection_color = Color(0.5, 0.5, 0.5, 1) 🔗
Color of the selection rectangle.
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.
int minimum_character_width = 4 🔗
Minimum horizontal space for the text (not counting the clear button and content margins). This value is measured in count of 'M' characters (i.e. this number of 'M' characters can be displayed without scrolling).
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 used for the text.
Font size of the LineEdit's text.
Texture for the clear button. See clear_button_enabled.
Background used when LineEdit has GUI 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.
Default background for the LineEdit.
Background used when LineEdit is in read-only mode (editable is set to false).
