**NAME**

''dgw::tvmixins'' - functionality extensions for the [ttk::treeview] widget such as sorting, tooltips, banding stripes, key based navigation.

**DESCRIPTION**

''dgw::tvmixins'' - The package ''dgw::tvmixins'' implements several ''snit::widgetadaptor''s which extend the standard *ttk::treeview* widget with different functionalities. Different adaptors can be chained together to add the required functionalities. Please note that most of the functionalities are not coded mainly by the author of the package [DDG] but just wrappers of the functionalities into ''snit::widgetadaptor''s for easy usage and combining the different properties and functionalities.

The following adaptors are currently available:

   * ''dgw::tvband'' - providing banding stripes (will be obsolete with Tcl/Tk 8.7)
   * ''dgw::tvfilebrowser'' - providing a interactive file browser widget with standard icons
   * ''dgw::tvksearch'' - key based navigation using Home and End keys as well as by typing starting letters
   * ''dgw::tksortable'' - adds easily sorting facilities to the treeview widget as well a ''<<SortEnd>>'' event
   * ''dgw::tooltip'' - adds row tooltips by providing ''<<RowEnter>>'' and ''<<RowLeave>>'' events
