DESCRIPTION

dgw::tvmixins - The package dgw::tvmixins implements several snit::widgetadaptors 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 teh functionalities are not coded mainly by the author of the package DDG but just wrappers of the functionalities into snit::widgetadaptors 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

# wrapper function 
proc fbrowse {path args} {
     set fb [dgw::tvtooltip [dgw::tvksearch [dgw::tvfilebrowser [dgw::tvband [ttk::treeview $path]] {*}$args]]]
