StyleBox¶
Inherits: Resource < Reference < Object
Inherited By: StyleBoxEmpty, StyleBoxFlat, StyleBoxLine, StyleBoxTexture
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.

Property Descriptions¶
float content_margin_bottom = -1.0
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 = -1.0
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 = -1.0
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 = -1.0
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 canvas item identified by the given RID.
The RID value can either be the result of CanvasItem.get_canvas_item called on an existing CanvasItem-derived node, or directly from creating a canvas item in the VisualServer with VisualServer.canvas_item_create.
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.
