SpinBox

继承： 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: Create a SpinBox, disable its context menu and set its text alignment to right.

    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;

See Range class for more options over the SpinBox.

Note: With the SpinBox's context menu disabled, you can right-click the bottom half of the spinbox to set the value to its minimum, while right-clicking the top half sets the value to its maximum.

Note: SpinBox relies on an underlying LineEdit node. To theme a SpinBox's background, add theme items for LineEdit and customize them. The LineEdit has the SpinBoxInnerLineEdit theme variation, so that you can give it a distinct appearance from regular LineEdit s.

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.

属性说明

HorizontalAlignment alignment = 0

• void set_horizontal_alignment ( value: HorizontalAlignment )
• HorizontalAlignment get_horizontal_alignment ( )

Changes the alignment of the underlying LineEdit.

float custom_arrow_step = 0.0

• void set_custom_arrow_step ( value: float )
• float get_custom_arrow_step ( )

If not 0, Range.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 ( value: bool )
• bool is_editable ( )

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

String prefix = ""

• void set_prefix ( value: String )
• 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 ( value: bool )
• 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 ( value: String )
• 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 ( value: bool )
• 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.

方法说明

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.
