Cluster to Tree


Recommended Posts

Thanks

 

Eventually I'll add the ability to edit an item and read back the cluster

 

Also right click and view an item such as an array as a waveform graph. If the item is another object then display its attributes as well.

 

The Variant Probe looks cool I'll take a closer look

      Hi,
      In a Mouse Down? on a tree, I need to know if the user clicked on a expand/contract symbol, because I need to discard clicking on items but I still need the expand/contract mechanism.
      I would need something similar to the InSymbol from the Point To Row Column method, but for the expand/contract symbol.
      How can I do that?

      Hi
       
      When I call the DLL, there is a structure:
      struct Signal { uint32 nStartBit; uint32 nLen; double nFactor; double nOffset; double nMin; double nMax; double nValue; uint64 nRawValue; bool is_signed; char unit[11]; char strName[66]; char strComment[201]; };  
       
      There is another  Message structure to the above Signal:
       
      struct Message { uint32 nSignalCount; uint32 nID; uint8 nExtend; uint32 nSize; Signal vSignals[513]; char strName[66]; char strComment[201]; }  
        The point is  Signal vSignals[513];
       
      I've tried to solve it like this,but the program will crash.
       
      How to create struct Message ,any good suggestions?  Thanks a lot.

      After working on the set cluster element by name xnode, it made me realize i could use the same concept to convert a variant array to a cluster. The technique is actually pretty simple, the xnode generates a case structure for each element in a cluster in cluster order, wherein a bundle by name is used to set the value and an unbundle by name is used to get the type, a variant to data is used to convert the data. This has some benefits over some methods, you are not limited to 255 elements, although that is not usually the case some of us are paranoid that clusterosaurus giganticous will be larger than expected. It also has a draw back  that is that when converting from a variant array all the elements must have unique, non-blank names, and this is usually the case. 

      I think this technique (though very brute-force) might be useful for some other things let me know what you guys think.

      This Xnode allows setting a cluster element by label string without using references. I pulled a great deal of inspiration from Hooovahhs Variant Array to cluster xnode, which i suppose this could be used for, another benefit is its not limited to 255 elements. Its mostly experimental because I haven't used it much.

      Is there any way to automatically wire an index array block to a bundle by name block?

      Auto-wire (pressing space) just adds one wire.
      Note that my cluster contains data of different types so converting the cluster to an array doesn't work.
      If there is a quick-drop shortcut for this I would be very impressed.
