Custom Tabs

class UI4.Tabs.BaseTab(*args, **kwargs)

Bases: BaseFrame

Base class for all UI tabs.

Inherits from UI4.Widgets.BaseWidgets.BaseFrame to provide handling of custom callbacks for actions and key events that are associated with user-defined keyboard shortcuts, and provides functions for storing and restoring settings per tab when loading and saving tab layouts.

Variables:

  • Icon – ✨ New in Katana 4.5: An icon to use next to the title of a tab in the tab bar of a pane, and for menu items that represent the tab type in the Tabs main menu and the Add Tab pane menu, unless MenuItemIcon is defined. The icon for a tab type of a given name can be retrieved by calling UI4.App.Tabs.GetTabIcon().

  • MenuItemIcon – ✨ New in Katana 4.5: An icon to use for menu items that represent the tab type in the Tabs main menu and the Add Tab pane menu. If MenuItemIcon is not defined, but Icon is defined, then Icon will be used for menu items that represent the tab type. The menu item icon for a tab type of a given name can be retrieved by calling UI4.App.Tabs.GetTabMenuItemIcon().
