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. https://docs.godotengine.org/en/3.5.1/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.

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. Renames the [Color] at [code]old_name[/code] to [code]name[/code] if the theme has [code]theme_type[/code]. If [code]name[/code] is already taken, this method fails. Renames the constant at [code]old_name[/code] to [code]name[/code] if the theme has [code]theme_type[/code]. If [code]name[/code] is already taken, this method fails. Renames the [Font] at [code]old_name[/code] to [code]name[/code] if the theme has [code]theme_type[/code].

Creates [code]theme_type[/code] if the theme does not have it. Sets the theme item of [code]data_type[/code] to [code]value[/code] at [code]name[/code] in [code]theme_type[/code]. Does nothing if the [code]value[/code] type does not match [code]data_type[/code]. Creates [code]theme_type[/code] if the theme does not have it. Marks [code]theme_type[/code] as a variation of [code]base_type[/code]. This adds [code]theme_type[/code] as a suggested option for [member Control.theme_type_variation] on a [Control] that is of the [code]base_type[/code] class. Variations can also be nested, i.e. [code]base_type[/code] can be another variation. If a chain of variations ends with a [code]base_type[/code] matching the class of the [Control], the whole chain is going to be suggested as options. [b]Note:[/b] Suggestions only show up if this theme resource is set as the project default theme. See [member ProjectSettings.gui/theme/custom]. 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. Theme's [StyleBox] item type. Maximum value for the DataType enum.
