This is a draft idea for a new feature in Riena. Currently the programmer always gets one ridget at a time in the controller. It would be nice if he could get a CollectionRidget or MetaRidget which contains multiple Ridgets. This CollectionRidget (not sure it is the right name) could then be used in two ways. a) you can iterate over its content and inspect the individual ridgets (pretty much the same as the IRidgetContainer) b) you can perform a single action which is automatically performed on all ridgets in the collection. As an extension when a action is not feaseable for a certain ridget it would be ignored for that action. The way to get such a collectionridget could be masked ridgetname, some meta language to filter by attribute or type, regex (still undecided) An example coll1 = getCollectionRidget("all visible ridgets"); coll1.setVisible(false); coll2 = getCollectionRidget("all text fields"); coll2.setMandatory(true); coll3 = getCollectionRidget("all childs of master"); coll3.setDisabled(true); coll4 = getCollectionRidget("all ridgets"); coll4.updateFromModel();
+1 A common use case in a Riena application is a SubModuleView with a an address that consists of firstname, lastname, street, zip textfields. Those textfields belong together, but we can't treat them as one collectionRidget/metaRidget. So I would like to have compound ridgetIds that consist of a prefix and the ridgetId identifying the single ridget. Then we could get a set of ridgets by a prefix in the SubModuleController that belong together: SubModuleView public void createPartControl(Composite parent){ UIControlsFactory.createText(parent, SWT.BORDER, "address.firstName"); UIControlsFactory.createText(parent, SWT.BORDER, "address.lastName"); } SubModuleController: public void configureRidgets(){ CollectionRidget address = getRidgetMatching("address.*"); address.setOutputOnly(true); } Now we could easily add or remove marker to a set of Ridgets.
looks good. However we have to make a list of APIs that we want to consider in the CollectionRidget. Does it implement IRidget or does it need to implement IMarkableRidget (which includes setOutputOnly) but is not implemented by all ridgets. Or should we have CollectionRidget and CollectionMarkableRidget implementation with different API ? Can you iterate over such a collection ? Can you specify a desired type or interface ? CollectionRidget collection = getRidgetMatching("address.*",ITextRidget.class); I also think that it would be better to have a ICollectionRidget rather than a CollectionRidget in the return type of getRidgetMatching and it should be getRidgetsMatching (plural) since we return a collection.
