Therefore, the model is flexible to represent anything from color to complicated tree-table construction. Thus the client of the model can track the changes in both the item model and any value it holds.įrom any item, the item model can get both the value model and the nested items. Instead, it returns the value model that can contain any data type and supports callbacks. The item model doesn’t return the data itself. The overall architecture is described in the following drawing: Instead, the user should subclass it to create a new model. It is not supposed to be instantiated directly. It’s abstract, and it defines the standard interface to be able to interoperate with the components of the model-view architecture. It is the application’s dynamic data structure, independent of the user interface, and it directly manages the nested data. The central component of the item widget. This pure abstract method must be reimplemented to generate custom widgets for specific item in the model. build_widget ( self : omni.ui._ui.AbstractItemDelegate, model : omni.ui._ui.AbstractItemModel, item : omni.ui._ui.AbstractItem = None, index : int = 0, level : int = 0, expanded : bool = False ) → None ¶ This pure abstract method must be reimplemented to generate custom widgets for the header table. ![]() build_header ( self : omni.ui._ui.AbstractItemDelegate, column_id : int = 0 ) → None ¶ This pure abstract method must be reimplemented to generate custom collapse/expand button. build_branch ( self : omni.ui._ui.AbstractItemDelegate, model : omni.ui._ui.AbstractItemModel, item : omni.ui._ui.AbstractItem = None, column_id : int = 0, level : int = 0, expanded : bool = False ) → None ¶ AbstractItemDelegate ¶ĪbstractItemDelegate is used to generate widgets that display and edit data items from a model. The object that is associated with the data entity of the AbstractItemModel. Puts cursor to this field or removed focus if focus_keyboard ( self : omni.ui._ui.AbstractField, focus : bool = True ) → None ¶ It’s implemented using the model-view pattern and uses AbstractValueModel as the central component of the system. The abstract widget that is base for any field, which is a one-line text editor.Ī field allows the user to enter and edit a single line of plain text. ![]()
