multi selection without using Ctrl

[mma]

Hi there.

I want to implement the following changes regarding the behavior of the MultiSelectionModel:

• Each click on a row should select that row and maintain all the previous selected rows
• Each click on a selected row should unselect it

This sounds very easy but I haven't managed to implement it.

Any ideas? Thanks!

I'm replying to my own post with the solution.

class ServiceTypeTableView {

public ServiceTypeList () {}

 

DefaultSelectionEventManager<ServiceType> customManager = DefaultSelectionEventManager.createCustomManager(new EventTranslator<ServiceType>() {

public boolean clearCurrentSelection(CellPreviewEvent<ServiceType> event) { 

return false;

}

public SelectAction translateSelectionEvent(CellPreviewEvent<ServiceType> event) {

return SelectAction.TOGGLE;

}

});

MultiSelectionModel<ServiceType> multiSelectionModel = new MultiSelectionModel<ServiceType>();

CellTable<ServiceType>() cellTable = new CellTable<ServiceType>();

cellTable.setSelectionModel(multiSelectionModel, customManager);

...

}

...

}
