clearing functions

A short cut I use to clear out my structures is to save an empty structure to file and reload it when I want to clear the existing structure.

wxtreeid

I can't save the ID.

Whenever I try I get error messages teling me the variable was never declared.

I add

Code: Select all

wxTreeItem ID  rootID;
rootID = theTree->AppendItem(...);
when it compiles it keeps telling me that rootID was never declared.
