SpinBox¶

Inherits: Range < Control < CanvasItem < Node < Object

An input field for numbers.

描述¶

SpinBox is a numerical input text field. It allows entering integers and floating point numbers.

Example:

var spin_box = SpinBox.new()
add_child(spin_box)
var line_edit = spin_box.get_line_edit()
line_edit.context_menu_enabled = false
spin_box.horizontal_alignment = LineEdit.HORIZONTAL_ALIGNMENT_RIGHT

var spinBox = new SpinBox();
AddChild(spinBox);
var lineEdit = spinBox.GetLineEdit();
lineEdit.ContextMenuEnabled = false;
spinBox.AlignHorizontal = LineEdit.HorizontalAlignEnum.Right;

The above code will create a SpinBox, disable context menu on it and set the text alignment to right.

See Range class for more options over the SpinBox.

Note: SpinBox relies on an underlying LineEdit node. To theme a SpinBox's background, add theme items for LineEdit and customize them.

Note: If you want to implement drag and drop for the underlying LineEdit, you can use Control.set_drag_forwarding on the node returned by get_line_edit.

Property Descriptions¶

HorizontalAlignment alignment = 0

void set_horizontal_alignment ( HorizontalAlignment value )
HorizontalAlignment get_horizontal_alignment ( )

Changes the alignment of the underlying LineEdit.

float custom_arrow_step = 0.0

void set_custom_arrow_step ( float value )
float get_custom_arrow_step ( )

If not 0, value will always be rounded to a multiple of custom_arrow_step when interacting with the arrow buttons of the SpinBox.

bool editable = true

void set_editable ( bool value )
bool is_editable ( )

If true, the SpinBox will be editable. Otherwise, it will be read only.

String prefix = ""

void set_prefix ( String value )
String get_prefix ( )

Adds the specified prefix string before the numerical value of the SpinBox.

bool select_all_on_focus = false

void set_select_all_on_focus ( bool value )
bool is_select_all_on_focus ( )

If true, the SpinBox will select the whole text when the LineEdit gains focus. Clicking the up and down arrows won't trigger this behavior.

String suffix = ""

void set_suffix ( String value )
String get_suffix ( )

Adds the specified suffix string after the numerical value of the SpinBox.

bool update_on_text_changed = false

void set_update_on_text_changed ( bool value )
bool get_update_on_text_changed ( )

Sets the value of the Range for this SpinBox when the LineEdit text is changed instead of submitted. See LineEdit.text_changed and LineEdit.text_submitted.

Method Descriptions¶

void apply ( )

Applies the current value of this SpinBox.

LineEdit get_line_edit ( )

Returns the LineEdit instance from this SpinBox. You can use it to access properties and methods of LineEdit.

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 CanvasItem.visible property.

Theme Property Descriptions¶

Texture2D updown

Sets a custom Texture2D for up and down arrows of the SpinBox.
