DirDialog always creates dir if non-existent

[schnepper]

When I use a DirDialog, a new directory is created if the user enters a non-existent name in the Location field.  I'd like to validate the name with app specific criteria and create the directory myself if desired.  This behavior occurs whether or not I specify wx.DD_DEFAULT_STYLE.  Is this correct behavior for this class?  Is there any way I can override it?  Is there a different widget I can use?

I am using python-wxgtk3.0 on Ubuntu 16.4.

Thank you.

wx.DD_DEFAULT_STYLE doesn't include the flag you need. Use
wx.DD_DIR_MUST_EXIST.

> wx.DD_DIR_MUST_EXIST: The dialog will allow the user to choose only
an existing folder. When this style is not given, a “Create new
directory” button is added to the dialog (on Windows) or some other way
is provided to the user to type the name of a new folder.

Thanks, James.  I tried that and it had no effect.  With or without that flag, the user is able to type a new value into the Location field and a new directory is created.  My guess is that it is a feature of the underlying GTK dialog.  What I want is for the user to be able to select an existing directory or specify a new directory without creating it.  I think I'll have to use a TreeCtl and populate it myself.  I've attached a short program that illustrates the problem.

You may want to start with the wx.GenericDirCtrl class.
