Known classes within UISkin:

Direct subclass:

This class in other games:
UDK

Represents a collection of UIStyles.

When a style is created, it is assigned a persistent STYLE_ID. All styles for a particular widget are stored in a single unreal package file. The root object for this package is a UISkin object. The resources required by the style may also be stored in the skin file, or they might be located in another package.

A game UI is required to have at least one UISkin package that will serve as the default skin. Only one UISkin can be active at a time, and all custom UISkins are based on the default UISkin. Custom UISkins may decide to override a style completely by creating a new style that has the same STYLE_ID as the skin to be replaced, and placing that skin into the StyleLookupTable under that STYLE_ID. Any styles which aren't specifically overridden in the custom UISkin are inherited from the default skin. By default, widgets will automatically be mapped to the customized version of the UIStyle contained in the custom UISkin, but the user may choose to assign a completely different style to a particular widget. This only changes the style of that widget for that skin set and any UISkin that is based on the custom UISkin. Custom UISkins can be hierarchical, in that custom UISkins can be based on other custom UISkins. Copyright 1998-2007 Epic Games, Inc. All Rights Reserved.

Properties[edit]

CursorMap[edit]

Type: Map{FName,struct FUIMouseCursor}

Modifiers: const, native, duplicatetransient

The cursors contained by this skin. Maps a unique tag (i.e. Arrow) to a cursor resource.

SoundCueMap[edit]

Type: Map{FName,class USoundCue*}

Modifiers: const, native, transient

Maps UI sound cue names to their corresponding sound cues. Used for quick lookup of USoundCues based on the UI sound cue name. Built at runtime from the SoundCues array.

SoundCues[edit]

Type: array<UISoundCue>

Modifiers: const, protected

the UI sound cues contained in this UISkin

StyleGroupMap[edit]

Type: Object.Map_Mirror{TLookupMap<FString>}

Modifiers: const, native, transient

Contains the style group names for this style and all parent styles.

StyleGroups[edit]

Type: array<string>

Modifiers: const, protected

The group names used by the styles in the skin package

StyleLookupTable[edit]

Type: Map{struct FSTYLE_ID,class UUIStyle*}

Modifiers: const, native, transient

maps STYLE_ID to the UIStyle that corresonds to that STYLE_ID. Used for quickly finding a UIStyle based on a STYLE_ID. Built at runtime as the UISkin serializes its list of styles

StyleNameMap[edit]

Type: Map{FName,class UUIStyle*}

Modifiers: const, native, transient

Maps StyleTag to the UIStyle that has that tag. Used for quickly finding a UIStyle based on a style tag. Built at runtime as the UISkin serializes its list of styles.

Styles[edit]

Type: array<UIStyle>

Modifiers: const, instanced, protected

the styles stored in this UISkin

Default values[edit]
