Re: [tracecompass-dev] Fw: Problems updating plugin using Trace Compass to Eclipse Oxygen SR3
|
Loic
I looked at the interval visibility problem a bit this morning and found out what's happening.
I have a class that extends CallstackPresentationProvider and overrides that classes getStateTable, getEventHoverTooltipInfo and getStateTableIndex methods with the intent to set color for the interval depending on specific attributes of the interval I get from the state system and also controls visibility of intervals. My getStateTableIndex method expects to get a CallStackEvent, but is now getting either a TimeEvent or a NamedTimeEvent object. Since my code didn't know what to do with them, it returns ITimeGraphPresentationProvider.INVISIBLE.
My extension of CallstackPresentationProvider does need access to the state system so I can query it in order for the view to work correctly.
I will look at the code you referenced to see what I need to do.
Thanks
Dave

Hi David,
We have undergone some major decoupling work to separate the core and
UI classes, which now exchange data through the data provider
interface.
It seems that you needed the ITmfStateSystem to populate your tooltips,
but we try not to access the state system in the UI now. The "new" way
to do it is to use the fetchTooltip method in ITimeGraphDataProvider.
The CriticalPathPresentationProvider, ControlFlowPresentationProvider
and ResourcesPresentationProvider contain examples using this API.
Your states might also not be colored because of missing getStateTable
and getStateTableIndex?
Hope this helps,
Loic
