PickFileRadio Class Reference
#include <pickfileradio.h>
Detailed Description
Radio button with associated file picker controls.The PickFileRadio class is a radio button with an associated button to choose a file, and an optional file name edit box. Its purpose is to ensure that while the radio button is selected, the chosen file name is never blank.
To achieve this, whenever the button is newly selected and the file name is currently blank, the file picker dialogue is displayed to choose a file. If the dialogue exits without a file being chosen, the radio button selection is reverted to the previously selected button in the parent button group.
The class handles the activation of the file picker dialogue (via a virtual method which must be supplied by deriving a class from this one). It also handles all enabling and disabling of the browse button and edit box when the enable state of the radio button is changed, and when the radio button selection changes.
