Property group 'Data'[edit]
ContextMenuData[edit]
Type: UIRoot.UIDataStoreBinding
Modifiers: private, editconst
Default value:
| Member | Value |
|---|---|
| RequiredFieldType | DATATYPE_Collection |
ToolTip[edit]
Type: UIRoot.UIDataStoreBinding
Modifiers: private
The tool tip for this widget; only relevant for widgets that implement the UIDataStoreSubscriber interface.
Property group 'Interaction'[edit]
[edit]
Type: UIRoot.UINavigationData
Controls which widgets are given focus when this widget receives an event that changes the currently focused widget.
PlayerInputMask[edit]
Type: byte
A bitmask representing the player indexes that this control will process input for, where the value is generated by left bitshifting by the index of the player. A value of 0xF indicates that this control will process input from all players. A value of 1 << 1 indicate that only input from player at index 1 will be acccepted, etc. So value of 3 means that this control processes input from players at indexes 0 and 1. Input from player indexes that do not match the mask will be ignored.
By default, the input mask comes from the scene. Widgets can override this value to allow more or less players to interact with that widget - this override value is stored in the upper 4 bits.

bEnableSceneUpdateNotifications[edit]
Type: bool
Indicates that this widget needs to perform work when the scene is updated. If TRUE, the widget will recieve calls to both PreSceneUpdate() and PostSceneUpdate().
bSupportsPrimaryStyle[edit]

Valid behavior flags are defined in UIRoot.uc, as consts which begin with PRIVATE_
StyleSubscribers[edit]
Type: array<UIStyleResolver>
Modifiers: transient
List of objects/components contained by this widget which contain their own style references. When this widget's style is resolved, each element in this list will receive a notification to resolve its style references as well.
Elements should be added to this list either from the native InitializeStyleSubscribers method [for native classes], the Initialized event [for non-native classes], or the native PostEditChange method (when e.g. components are created or removed using the UI editor's property window).
You should NEVER add elements to this array using defaultproperties, since interface properties will not be updated to point to the subobject/component instance when this widget is created.
WidgetID[edit]
Type: UIRoot.WIDGET_ID
Modifiers: noimport
Unique identifier for this widget
Default values[edit]

Delegates[edit]
OnClicked[edit]
Called when the widget is no longer being pressed. Not implemented by all widget types.
The difference between this delegate and the OnPressRelease delegate is that OnClick will only be called on the widget that received the matching key press. OnPressRelease will be called on whichever widget was under the cursor when the key was released, which might not necessarily be the widget that received the key press.
Parameters:
- EventObject - Object that issued the event.
- PlayerIndex - Player that performed the action that issued the event.
Returns:
- return TRUE to prevent the kismet OnClick event from firing.
OnCloseContextMenu[edit]
Called when the system wants to close the currently active context menu.
Parameters:
- ContextMenu - the context menu that is going to be closed
- PlayerIndex - the index of the player that generated the request for the context menu to be closed.
Returns:
- TRUE to allow the specified context menu to be closed; FALSE to prevent the context menu from being closed. Note that there are certain situations where the context menu will be closed regardless of the return value, such as when the scene which owns the context menu is being closed.
OnContextMenuItemSelected[edit]
Called when the user selects a choice from a context menu.
Parameters:
- ContextMenu - the context menu that called this delegate.
- PlayerIndex - the index of the player that generated the event.
- ItemIndex - the index [into the context menu's MenuItems array] for the item that was selected.
OnCreate[edit]
Called when this widget is created
Parameters:
- CreatedWidget - the widget that was created
- CreatorContainer - the container that created the widget
OnDoubleClick[edit]
Called when the widget has received a double-click input event. Not implemented by all widget types.
Parameters:
- EventObject - Object that issued the event.
- PlayerIndex - Player that performed the action that issued the event.
OnOpenContextMenu[edit]
Called when the user right-clicks (or whatever input key is configured to activate the ShowContextMenu UI input alias) this widget. Provides a way for widgets to customize the context menu that is used or prevent the context menu from being shown entirely.
For script customization of the context menu, a custom context menu object must be assigned to the CustomContextMenu variable. It is possible to provide data for the context menu without creating or modifying any existing data stores. First, get a reference to the scene's default context menu (GetScene()->GetDefaultContextMenu()). Add the desired elements to the scene's data store then bind the context menu to that data field.
Parameters:
- Sender - the widget that will be displaying the context menu
- PlayerIndex - index of the player that generated the input event that triggered the context menu display.
- CustomContextMenu - to provide a custom tooltip implementation, fill in in this value and return TRUE. The custom context menu will then be activated by native code.
Returns:
- return FALSE to prevent a context menu from being shown, including any from parent widgets. Return TRUE to indicate that the context menu for this widget can be displayed; if a value is not provided for CustomContextMenu, the default context menu will be displayed, using this widget's context menu data binding to generate the items.
OnPostSceneUpdate[edit]
Called immediately after the scene performs an update. Only called if assigned and the value of bEnableSceneUpdateNotifications is true.
OnPreSceneUpdate[edit]
Called immediately before the scene performs an update. Only called if assigned and the value of bEnableSceneUpdateNotifications is true.
OnPressed[edit]
Called when this widget is pressed. Not implemented by all widget types.
Parameters:
- EventObject - Object that issued the event.
- PlayerIndex - Player that performed the action that issued the event.
OnPressRelease[edit]
Called when the widget is no longer being pressed. Not implemented by all widget types.
Parameters:
- EventObject - Object that issued the event.
- PlayerIndex - Player that performed the action that issued the event.
OnPressRepeat[edit]
Called when the widget been pressed and the user is holding the button down. Not implemented by all widget types.
Parameters:
- EventObject - Object that issued the event.
- PlayerIndex - Player that performed the action that issued the event.
OnRefreshSubscriberValue[edit]
Called when this widget receives a call to RefreshSubscriberValue.
Parameters:
- Sender - the widget that is refreshing their value
- BindingIndex - optional parameter for indicating which data store binding is being refreshed, for those objects which have multiple data store bindings. How this parameter is used is up to the class which implements this interface, but typically the "primary" data store will be index 0, while values greater than FIRST_DEFAULT_DATABINDING_INDEX correspond to tooltips and context menus.
Returns:
- TRUE to indicate that this widget is going to refresh its value manually.
OnValueChanged[edit]
Called when the value of this UIObject is changed. Only called for widgets that contain data values.
Parameters:
- Sender - the UIObject whose value changed
- PlayerIndex - the index of the player that generated the call to this method; used as the PlayerIndex when activating UIEvents; if not specified, the value of GetBestPlayerIndex() is used instead.
