StyleBox

Inherits: Resource < Reference < Object

Base class for drawing stylized boxes for the UI.

Description

StyleBox is Resource that provides an abstract base class for drawing stylized boxes for the UI. StyleBoxes are used for drawing the styles of buttons, line edit backgrounds, tree backgrounds, etc. and also for testing a transparency mask for pointer signals. If mask test fails on a StyleBox assigned as mask to a control, clicks and motion signals will go through it to the one below.

Note: For children of Control that have Theme Properties, the focus StyleBox is displayed over the normal, hover or pressed StyleBox. This makes the focus StyleBox more reusable across different nodes.

Properties

Methods

Property Descriptions

• float content_margin_bottom

The bottom margin for the contents of this style box. Increasing this value reduces the space available to the contents from the bottom.

If this value is negative, it is ignored and a child-specific margin is used instead. For example for StyleBoxFlat the border thickness (if any) is used instead.

It is up to the code using this style box to decide what these contents are: for example, a Button respects this content margin for the textual contents of the button.

get_margin should be used to fetch this value as consumer instead of reading these properties directly. This is because it correctly respects negative values and the fallback mentioned above.

• float content_margin_left

The left margin for the contents of this style box. Increasing this value reduces the space available to the contents from the left.

Refer to content_margin_bottom for extra considerations.

• float content_margin_right

The right margin for the contents of this style box. Increasing this value reduces the space available to the contents from the right.

Refer to content_margin_bottom for extra considerations.

• float content_margin_top

The top margin for the contents of this style box. Increasing this value reduces the space available to the contents from the top.

Refer to content_margin_bottom for extra considerations.

Method Descriptions

• void draw ( RID canvas_item, Rect2 rect ) const

Draws this stylebox using a CanvasItem with given RID.

You can get a RID value using Object.get_instance_id on a CanvasItem-derived node.

• Vector2 get_center_size ( ) const

Returns the size of this StyleBox without the margins.

• CanvasItem get_current_item_drawn ( ) const

Returns the CanvasItem that handles its CanvasItem.NOTIFICATION_DRAW or CanvasItem._draw callback at this moment.

• float get_default_margin ( Margin margin ) const

Returns the default value of the specified Margin.

• float get_margin ( Margin margin ) const

Returns the content margin offset for the specified Margin.

Positive values reduce size inwards, unlike Control‘s margin values.

• Vector2 get_minimum_size ( ) const

Returns the minimum size that this stylebox can be shrunk to.

• Vector2 get_offset ( ) const

Returns the “offset” of a stylebox. This helper function returns a value equivalent to Vector2(style.get_margin(MARGIN_LEFT), style.get_margin(MARGIN_TOP)).

• void set_default_margin ( Margin margin, float offset )

Sets the default value of the specified Margin to given offset in pixels.

• bool test_mask ( Vector2 point, Rect2 rect ) const

Test a position in a rectangle, return whether it passes the mask test.
