A mixin class to help simple components adapt to member edit conventions.
Component classes derived from this class can define methods decorated with "@leaf", which use the SDS/2 Dialog API to define their user interface. These methods will be used to populate leaves in the member edit screen. Each leaf method must return a model (as defined by the Dialog API) that will be used by that leaf's Subdialog.
The derived class should also provide a member called "column_title", a string which will be used to label the component's column, a member called "column_foldname" to specify the uuid used to store the user"s preference for folding the column, and "column_defaultfoldstate" to specify the fold state when the user's preference is not known. An attribute "column_sortkey" may be specified to control the presentation order of columns.
ComponentUIHelper also provides obvious implementations for methods required by the member edit protocol, CreateUI, Load, Save, Reset, and Finalize, so component author's need not worry about providing them (unless something more than the obvious implementation is required).
See Dialog documentation for more on creating user interfaces with the Dialog library.
Usage:
class MyComponent(ComponentUIHelper): def __init__(self): self.column_title = 'My Component' self.column_foldname = 'aedf6b0d-7343-434c-8a06-01db14b072e1' self.column_defaultfoldstate = False self.color = 'Red' @leaf("My Leaf", 0, '7e6b96fb-c23b-4c40-af17-6f6cc706bc66', False): def create_my_leaf(self, subdialog): subdialog.menu('color', ['Red', 'Orange', 'Yellow', 'Green', 'Blue', 'Indigo', 'Violet'], 'Red', label="Color:") return [self]
