StatusBar is the component that sits at the bottom of each MainFrame, between the folder panels and command bar. There is one and only one StatusBar per MainFrame, created by the associated MainFrame. It can be hidden, but the instance will always remain, until the MainFrame is disposed.

StatusBar is used to display info about the total/selected number of files in the current folder and current volume's free/total space. When a folder is being changed, a waiting message is displayed. When quick search is being used, the current quick search string is displayed.

StatusBar receives LocationListener events when the folder has or is being changed, and automatically updates selected files and volume info, and display the waiting message when the folder is changing. Quick search info is set by FileTable.QuickSearch.

When StatusBar is visible, a Thread runs in the background to periodically update free/total space volume info. This thread stops when the StatusBar is hidden.
