The selector is the window in which files to be viewed are selected. The selector consists of two panes. The directory pane and the file pane. The directory pane can be turned off if desired.
The directory pane lets the user select a directory from which to view files. Clicking on a directory loads all the image files in that directory into the file pane. On startup specific files can be loaded into the file pane by specifing them on the command line.
The file pane shows a list of files either as a list with details or as image thumbnails. The type of view can be selected via the View menu. Clicking on a file selects and loads that file. If the viewer is visible the new image will be displayed. If the view is hidden double clicking on the image will open the viewer. Pressing either Enter key also switches to the viewer.
