Abstract base class for defining stylized boxes for UI elements.

|
[StyleBox] is an abstract base class for drawing stylized boxes for UI elements. It is used for panels, buttons, [LineEdit] 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.
|
|
[b]Note:[/b] For control nodes that have [i]Theme Properties[/i], the [code]focus[/code] [StyleBox] is displayed over the [code]normal[/code], [code]hover[/code] or [code]pressed[/code] [StyleBox]. This makes the [code]focus[/code] [StyleBox] more reusable across different nodes.

|
Virtual method to be implemented by the user. Returns a custom minimum size that the stylebox must respect when drawing. By default [method get_minimum_size] only takes content margins into account. This method can be overridden to add another size restriction. A combination of the default behavior and the output of this method will be used, to account for both sizes.

|
Draws this stylebox using a canvas item identified by the given [RID].
|
|
The [RID] value can either be the result of [method CanvasItem.get_canvas_item] called on an existing [CanvasItem]-derived node, or directly from creating a canvas item in the [RenderingServer] with [method RenderingServer.canvas_item_create].

<member name="content_margin_bottom" type="float" setter="set_content_margin" getter="get_content_margin" default="-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.
|
|
[method 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.

<member name="content_margin_left" type="float" setter="set_content_margin" getter="get_content_margin" default="-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 [member content_margin_bottom] for extra considerations.

<member name="content_margin_right" type="float" setter="set_content_margin" getter="get_content_margin" default="-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 [member content_margin_bottom] for extra considerations.

|
|
<member name="content_margin_top" type="float" setter="set_content_margin" getter="get_content_margin" default="-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.
