Detailed Description

Subclass of QFileDialog with additional functionality.

IMPORTANT: This class needs to be checked when the Qt version changes! Specifically: 1) The label at the bottom assumes that the layout is a QGridLayout, where the first column is for a label and the rest can be used for a widget. 2) As of Qt 4.3.4, the QFileDialog::filesSelected() signal is NOT emitted whenever the selection changes, but only when the selection is finalized. Because we're using a label to keep track of the current selection, this class uses a timer to update the label at a set time to the current selection. This is slightly inefficient, but there's no better way to do it without making our own file chooser dialog.
