[Connect C++] Query properties of a GroupedHole element

Unknown said:

I've spent some time on looking through the documentation but I didn't find a solution

I'm with you on that.  Trying to write code while consulting the MicroStationAPI help is equivalent to writing a new Shakespeare play with the aid of a dictionary.

There's one delivered example that bears tangentially on your question: in ElementsExample\ElementsExampleQueryTool.cpp you'll see how to use a ElementPropertiesGetterPtr.

I've tried to use the ElementPropertiesGetterPtr and it works fine on other element types (lines, linestrings, cells, shared cells etc) but it doesn't work on GroupedHole elements. The color returned got some very strange value like 1880678415...

I've just tested it again and now I can see why. The originally returned value was COLOR_BY_LEVEL and as I tried to get the color from the level, I didn't see that the LevelHandle was not OK.

Here is my code:

UInt32 color = propGetter->GetColor();
lvlHandle = eh.GetDgnModelP()->GetFileLevelCache().GetLevel(propGetter->GetLevel());

if (color == COLOR_BYLEVEL)
    color = lvlHandle.GetByLevelColor().GetColor();
