RE: [platform-debug-dev] Flexible Viewer Help

["Chuong, Patrick" <pchuong@xxxxxx>]

Hi Pawel,

 

Thanks for the input.

 

I had extended the LabelUpdate class to implements a new ICheckable interface, this allows the ElementLabelProvider to set the state of the checkbox in the retrieveLabel method. I didn’t add the new checkbox methods directly to ILabelUpdate, because I am not sure whether the derived classes for ILabelUpdate should allow check state or not.

 

I also added a listener through an adapter mechanism in the DebugElementAdapterFactory, IElementCheckListener, and IBreakpoint object returns this listener for check state changes, it can also adapts to breakpoint container as needed.

 

Do you think this change requires new bug # to track or it can be part of the breakpoint view changes?

 

Regards,

Patrick

 

P.S. I have the prototype view that works on the flexible hierarchy, it can be demo if need for the next meeting. However, the breakpoint grouping remains an issue. I think this also needs to be extendable by the model provider for the current debug context as well.

Hi Patrick,
Now I remember the first wrinkle in trying to use the flexible hierarchy view in BP view.... Currently the flexible hierarchy viewer doesn't support checkmarks, and it's something that will need to be added. 

It seems most appropriate to add a new provider (e.g. IElementCheckedProvider), or to extend the label provider and updates.  The provider should allow for setting the checked and grayed state of the checkbox.  The main complication with this extension is the fact that the checkboxes are created as soon as the tree items are created and potentially before the model has a chance to create the  elements behind the virtual items.  IMO the most logical thing to do in those cases would be to just ignore the user's check request until the initial checked state could be retrieved.

Cheers,
Pawel

P.S. Yes it's a significant undertaking, but at least we're only on M1 :-)

Hi,

 

I am trying to use the flexible viewer provided by the platform. I am not able know able to figure out how to initialize the checkbox state for a virtual tree. Is any one came across this issue and could give me a pointer how to create virtual tree with checkbox?

 

I pretty much follow the variables view and modules view to implements my checkbox view, with the additional of the SWT.CHECK flag for the view style. But I don’t know how to initialize the checkbox state.

 

Thanks,

Patrick
