Hi Guys,
I am not able to understand the meaning of command
*mergehistorystate "" ""
in TCL/TK. I searched on the internet but still I didn't understand why it is used for. I found this command in command.tcl file on hypermesh when I was splitting the surface by nodes. If anyone knows about it, please help me with this.
Your help is much appreciated.
Thanks and regards.
I am not sure exactly what it does but the "history state" is part of the undo/redo functionality. In my command.tcl file it always came after a *endnotehistorystate which is always accompanied by a *startnotehistorystate that are just basically saying this is an undo "block" or undo everything in here when an undo is preformed.
If you are trying to write a script these commands need not be included. If you are trying to make undo work with your script then you will need them but that is a whole other can of worms.
By the way there is a "HyperWorks Scripts & Customizations" topic that you can add (you can have multiple topics) that might reach more coders for questions like this.
