/**
|
|
Creates a dialog box to choose a file or directory to load or save.
|
|
|
|
To use a FileChooser:
|
|
- create one (as a local stack variable is the neatest way)
|
|
- call one of its browseFor.. methods
|
|
- if this returns true, the user has selected a file, so you can retrieve it
|
|
with the getResult() method.
|
|
|
|
e.g. @code
|
|
void loadMooseFile()
|
|
{
|
|
FileChooser myChooser ("Please select the moose you want to load...",
|
|
File::getSpecialLocation (File::userHomeDirectory),
|
|
"*.moose");
|
|
|
|
if (myChooser.browseForFileToOpen())
|
|
{
|
|
File mooseFile (myChooser.getResult());
|
|
|
|
loadMoose (mooseFile);
|
|
}
|
|
}
|

@endcode
