Theme for controls. A theme for skinning controls. Controls can be skinned individually, but for complex applications, it's more practical to just create a global theme that defines everything. This theme can be applied to any [Control]; the Control and its children will automatically use it. Theme resources can alternatively be loaded by writing them in a [code].theme[/code] file, see the documentation for more information. $DOCS_URL/tutorials/ui/gui_skinning.html Adds an empty theme type for every valid data type. [b]Note:[/b] Empty types are not saved with the theme. This method only exists to perform in-memory changes to the resource. Use available [code]set_*[/code] methods to add theme items. Clears all values on the theme. Sets the theme's values to a copy of the default theme values. Sets the theme's values to a copy of a given theme. Returns all the [Color]s as a [PoolStringArray] filled with each [Color]'s name, for use in [method get_color], if the theme has [code]node_type[/code]. Returns all the [Color] types as a [PoolStringArray] filled with unique type names, for use in [method get_color] and/or [method get_color_list]. Returns all the constants as a [PoolStringArray] filled with each constant's name, for use in [method get_constant], if the theme has [code]node_type[/code]. Returns all the constant types as a [PoolStringArray] filled with unique type names, for use in [method get_constant] and/or [method get_constant_list]. Returns all the [Font]s as a [PoolStringArray] filled with each [Font]'s name, for use in [method get_font], if the theme has [code]node_type[/code]. Returns all the [Font] types as a [PoolStringArray] filled with unique type names, for use in [method get_font] and/or [method get_font_list]. Returns all the icons as a [PoolStringArray] filled with each [Texture]'s name, for use in [method get_icon], if the theme has [code]node_type[/code]. Returns all the icon types as a [PoolStringArray] filled with unique type names, for use in [method get_icon] and/or [method get_icon_list]. Returns all the [StyleBox]s as a [PoolStringArray] filled with each [StyleBox]'s name, for use in [method get_stylebox], if the theme has [code]node_type[/code]. Valid [code]node_type[/code]s may be found using [method get_stylebox_types]. Returns all the [StyleBox] types as a [PoolStringArray] filled with unique type names, for use in [method get_stylebox] and/or [method get_stylebox_list]. Returns all the theme items of [code]data_type[/code] as a [PoolStringArray] filled with each theme items's name, for use in [method get_theme_item] or a data type specific method, if the theme has [code]node_type[/code]. Valid [code]node_type[/code]s may be found using [method get_theme_item_types] or a data type specific method. Returns all the theme items of [code]data_type[/code] types as a [PoolStringArray] filled with unique type names, for use in [method get_theme_item], [method get_theme_item_list] or data type specific methods. Returns all the theme types as a [PoolStringArray] filled with unique type names, for use in other [code]get_*[/code] functions of this theme. [b]Note:[/b] [code]node_type[/code] has no effect and will be removed in future version. Returns [code]true[/code] if this theme has a valid [member default_font] value. Adds missing and overrides existing definitions with values from the [code]other[/code] [Theme]. [b]Note:[/b] This modifies the current theme. If you want to merge two themes together without modifying either one, create a new empty theme and merge the other two into it one after another. Removes the theme type, gracefully discarding defined theme items. If the type is a variation, this information is also erased. If the type is a base for type variations, those variations lose their base. The default font of this [Theme] resource. Used as a fallback value for font items defined in this theme, but having invalid values. If this value is also invalid, the global default value is used. Use [method has_default_font] to check if this value is valid. Theme's [Color] item type. Theme's constant item type. Theme's [Font] item type. Theme's icon [Texture] item type.
