Detailed Description
Class providing a window containing a file listbox, an OK button and a Cancel button. Designed to allow users selection a file from the filesytem. When a file is selected the requester will automatically close.
To read the value of the selected option or options, you should listen for the value changed event. This will fire when the user double-clicks an option or clicks the OK button.
To add this class to a project:
- Enable libfat in the makefile by changing the line that reads LIBS := -lnds9 to LIBS := -lfat -lnds9
- Call "fatInitDefault();" somewhere in your setup code.
Note that including libfat increases the ROM size by ~100K. Also note that this code is not compatible with the SDL build of Woopsi.
