Crash when doubleclicking on a treeview node

[Hion-V]

As the title suggests the library makes my program crash when a node is doubleclicked

Expected Behavior

Either nothing or the node collapsing/ expanding, I have no idea.

Steps to Reproduce (for bugs)

1. Create a treeview that's populated with nodes
2. Compile for Linux
3. Doubleclick on any of the nodes
4. ???
5. Profit

Hi, I'm away currently and won't be back till Monday. However, the first thing I noticed is you are using 1.6.0, can you try with git versions of both haxeui-core and haxeui-openfl? It's likely it will be fixed there.

Cheers, Ian

I am not using the git version because my app won't compile with it because MenuEvent doesn't work in the git version.

[Hion-V]

I might try to see if this specific issue is fixed in the git version however.

[Hion-V]

This issue does appear resolved on the git version. I have also figured out that MenuEvent isn't missing in the git version but has been moved to a different source file.
