Detailed Description

New file selector class.


Running the file selector

void MyClass::runFileSelector ()
if (selector)
selector->addFileExtension (CFileExtension ("AIFF", "aif", "audio/aiff"));
selector->setDefaultExtension (CFileExtension ("WAVE", "wav"));
selector->setTitle("Choose An Audio File");
selector->run (this);
selector->forget ();

Getting results

CMessageResult MyClass::notify (CBaseObject* sender, IdStringPtr message)
CNewFileSelector* sel = dynamic_cast<CNewFileSelector*>(sender);
if (sel)
// do anything with the selected files here
return parent::notify (sender, message);
