Tree.InsertNode - why so slowly?

[lib]

Some times (not each call) this function waste a lot of time. Is it normal?

Example:

t1 = DLL.CallFunction("kernel32.dll", "GetTickCount", "", DLL_RETURN_TYPE_INTEGER, DLL_CALL_STDCALL);
result = Tree.InsertNode(DEFAULT_NAMEDATABASE, table.NodeIndex, table);
t2 = DLL.CallFunction("kernel32.dll", "GetTickCount", "", DLL_RETURN_TYPE_INTEGER, DLL_CALL_STDCALL);

In my case t2-t1 is about 15-16ms sometimes. Sometimes it is ok (0 ms).

Try setting update false/true.

I have learned properties of all Tree object but there is no property like Tree.SetUpdate.. Could you post an example? You mean SetEnabled property? If any object (Tree and etc) disabled it won't be redraw while its properties changing?

Thanks

Sorry, I figured it would have the option as the ListBox does, seems its not about consistency.

15-16ms is not so large time
that means you can insert 66 node per second

notice that GetTickCount calculate the time before and after a script
so
it depends on script and any other process running like av , explorer ...... etc
not the script only

so it gives different results to the same script

[startup]

GetTickCount
calculate the time that the pc takes
not the time that the action script takes

If you want to insert a number of nodes, you can use

Application.SetRedraw(false);

before you start the insertions, and

Application.SetRedraw(true);

once you are done. This way, the control won't be redrawn on each insertion and the whole process may perform much faster.
