Detailed Description

File selector dialog class.

Library: ilvadvgdt

The IlvFileChooser class enables you to browse through a directory hierarchy and select a file name or directory. To modify this dialog, create an IlvFileChooserOptions object with the options you wish to change.

Warning: Note that by default, all the bitmaps that are used by this class are PNG bitmaps. If you plan to statically link an application that uses IlvFileChooser, you will have to explicitly include the header file <ilviews/bitmaps/png.h> in one of your application source file and add the ilvpng library to your link command.
Similarly, if you replace the default bitmaps by your own and wish to link statically, you will have to make sure the appropriate bitmap format header files are included in one of your object files, and that the corresponding libraries are added to the link command for your application.
