Thanks again 🙂 . I did notice that in IProviderCursorHandles, all the OnCursorAction_ ... and OnCustomBarEvent functions only get hit when clicking/hovering/... over parameter control points, not the dynamic created control points. Strangely enough, the GetHandle... functions of that class do get hit when clicking/hovering/... over dynamic created control points. Has anyone notice the same thing?

Thanks Wouter, the creation of the control points works now. A question: is it possible to have a custom data bar while dragging a custom control point? I tried this in a overwrite of VWParametric_EventSink::OnCursorEvent( ParametricMessage* message ), case message->fAction = ParametricCursorMessage::EAction::kAction_MouseDown: CustomBarRefID outCustomBarRefID; bool b = false; b = gSDK->CustomBarCreate( 1, outCustomBarRefID ); b = gSDK->CustomBarInstall( outCustomBarRefID ); CustomBarFieldInfo fieldInfo; fieldInfo.fFieldLabel = "Length"; fieldInfo.fFieldValue = 1000; fieldInfo.fIsEditable = true; fieldInfo.fIsLocked = false; b = gSDK->CustomBarSetFieldInfo( outCustomBarRefID, 0, fieldInfo ); // b = gSDK->CustomBarRelease( outCustomBarRefID ); It still shows the default data bar but all values are empty. When I don't use gSDK->CustomBarRelease() (because it returns false) the data bar values are still empty, except the first (X) has a reversed S in it... I tried the same in and overwrite of IProviderCursorHandles::OnCursorAction_MouseDown( ICursorHandleActionContext* context ) but that one doesn't even get hit (even when I remove the overwrite of VWParametric_EventSink::OnCursorEvent( ParametricMessage* message )). This doesn't work either. TXString lab = "Length"; gSDK->SetDataDisplayBarField( 0, barLength, lab ); gSDK->SetDimUserBarValue( 0, 1000 ); In the VWTool_EventSink class, I found these functions, but I don't think I should use them because the Control Points are part of the object, not the tool. Also, when I implement them, they don't get hit. virtual void OnCustomBar_Setup(); virtual void OnCustomBar_Setdown(); virtual void OnCustomBar_UpdateValues(); virtual void OnCustomBar_LockValue(size_t fieldIndex, const TXString& userString); virtual void OnCustomBar_UnlockValue(size_t fieldIndex); virtual void OnCustomBar_LockValue(const CustomBarLockValueData& lockData); virtual void OnCustomBar_UnlockValue(const CustomBarLockValueData& lockData); Did anyone got this to work in their PIO?

Hi all Is anyone able to create Control Points on the fly? On this page (and also in the SDK manual) it's explained but I think this is some old code because I can't find any case of that switch (action) in the SDK.

I'm using gSDK->AddObjectToContainer() now and it seems to work fine. But I'll keep that InsertBefore/InsertAfter in mind whenever something strange pops up on the way, thanks for the tip! And you're right about the nullptr, the function will already create a new instance. I've been out of the whole computer/programming/Vectorworks world for several years so it's all a bit rusty, but it's slowly coming back 🙂 .

Hooray, that did the trick indeed 😄 . I got thrown off because in check 5, I did get the container info (the layer) so I assumed I didn't had to add it another time... Never a boring day with the SDK 🙂 . Thanks for the help!

I forget to mention, I tried the same with the gSDK->... functions too, same result, no symbol instance in the drawing.

Hi all I want to create a symbol definition and place an instance of it in the drawing (active layer). I'm probably missing the obvious here, but why doesn't this work: // 1. Create the symbol definition, add a line to it. TXString symName = "a unique symbol name"; VWSymbolDefObj symDef = gSDK->CreateSymbolDefinition(symName); symDef.AddObject(gSDK->CreateLine(WorldPt(0, 0), WorldPt(100, 100))); // 2. Reset to make the line visible in the symbol definition. symDef.ResetObject(); // 3. Refresh Res Browser to make symbol def visible. gSDK->RefreshResourceBrowserResourcesList(true); // 4. Place this symbol on the active layer (reset all just to be sure) VWSymbolObj symInst(symDef, WorldPt(0,0), 0); symInst.ResetObject(); symInst.SetVisible(true); symInst.ResetObjectsVisibility(); // 5. as a check: get the name of the layer the object is placed on. MCObjectHandle* pOutContainerHandle = new MCObjectHandle; short* pOutContainerType = new short; double* pOutContainerScale = new double; symInst.GetContainerInfo(pOutContainerHandle, pOutContainerType, pOutContainerScale); VWLayerObj lay(*pOutContainerHandle); TXString layName = lay.GetName(); // The name of the layer is correct, but the symbol is not visible/selectable on the active layer. Step 1, 2, 3 works fine, the symbol definition is created and visible in the Resource Browser. I can manually drag and drop it in the drawing. Step 4 and 5 seems to work too, I get the container info (the active layer) but still, I don't see the symbol in the drawing. Oh, and I'm doing this in CMenu_EventSink::DoInterface();
