I'm currently testing around on the TShell* controls and came to the
ShowRoot property now.
1. Why is this property duplicated in Options as well?
2. What's the purpose of this property? I personally thought that it would
allow me to show/hide the root node (e.g. on Linux "/" by default or the
root set in the "Root" property), but changing it to "false" just hides all
extend signs in the tree (and thus the subdirectories can no longer be
extended).
I don't know, but both Options and ShowRoot are implemented by
TCustomTreeView, not in the shell controls.
Delphi docs for reference:
http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/ComCtrls_TCustomTreeView_ShowRoot.html
http://lazarus-ccr.sourceforge.net/docs/lcl/comctrls/tcustomtreeview.options.html
Options doesn't seam to exist in Delphi. Probably someone added this
option because he didn't know that the ShowRoot property existed.
Thanks for the answer.
What an unintuitive property...
Regards,
Sven
