identifyGraphicsOverlays for some sidcs not working

NorbertThoden

I create a GraphicsOverlay and put a advanced symbol on it. This is done using a DictionaryRenderer (MIl2525D)

The task "identifyGraphicsOverlays" is done on a sidc "10032500001406030000" // SymbolSet/Entity = 25 140603

(line with arrow)

The slot "identifyGraphicsOverlaysCompleted" is called but with an empty result list 😞

Conclusion:

Many (maybe all) multipoint sidcs can´t be identified/picked.

Hi Norbert - thanks for posting your question. Do you have any example code you could share?

One other thing which might be worth double-checking is that your are connecting to the correct signal for the task you have started. E.g MapQuickView has 2 signals:

identifyGraphicsOverlayCompleted
identifyGraphicsOverlaysCompleted

corresponding to the 2 tasks:

identifyGraphicsOverlay
identifyGraphicsOverlays

Note the "s" at the end of "GraphicsOverlay" for the 2nd signal (this has caught me out before).

It might also be worth connecting to the errorOccurred signal if you haven't already done so.

Thanks,

Luke

Hi Luke!

Thanks for the quick answer!

We are using the pure C++, no Quick/QML.

And yes, i know the two similar named signals/slots.

If i use another sidc (like a point symbol) than it works. (Since ~1,5 years)

example - will try to build...

Hi Luke!

Description:

I create two PictureMarker as dummy object:

- one in green and a size of 20;
- one in red and a size of 10;

I add an attribute to distinguish them.

I create an advanced symbol: 10032500001406030000 // 25 140603

The problem is related to the identifyGraphicsOverlays method which is overloaded:

// First overload:
// Identify the topmost graphics in all the graphics overlays at the specified screen coordinates.
```
TaskWatcher identifyGraphicsOverlays(double screenX, double screenY, double tolerance, bool returnPopupsOnly);
```

// Second overload:
Identify which graphics in all the graphics overlays appear at the specified screen coordinates.

TaskWatcher identifyGraphicsOverlays(double screenX, double screenY, double tolerance, bool returnPopupsOnly, int maximumResultsPerOverlay);

Behaviour:

For the first overload: (topmost)
The the two PictureMarker can be picked/identified as well as advanced symbol.
(They can be recognized the the attribute

For the second overload: (more than one result per GraphicsOverlay)
The two PictureMarker can be picked/identified but not the advanced symbol

This is true for RenderingMode::Dynamic.

Using RenderingMode::Static, the advanced symbol could never be identified/picked....

My Conclusion:

The second overload does not return the advanced symbol

Do i miss something?

Thanks Norbert - that does sound like a possible bug. I'll try and reproduce with your example code and log a bug.
