A FileChooserDialog is a modal dialog to allow choosing a file. The full file name is returned, or nil if no selection was made. Users can enter a pattern in the text input field that will be read as a directory path and an optional pattern (see comments about pattern in my superclass) to define the files in the file list. Normal usage would be + myFilename := FileChooserDialog openOn: myApplicationDefaultDirectory pattern: '*.myapp' message: 'Choose the file to load' - myFilename := FileChooserDialog openOn: myApplicationDefaultDirectory pattern: '*.myapp' to find a file with a name matching *.myapp and with the directory initial choice set to myApplicationDefaultDirectory. It would be quite possible to choose a file from any other directory and with any other pattern match if the user wishes, so the file name must be carefully checked. Simpler usage might be myFilename := FileChooserDialog open or myFilename := FileChoosverDialog openOn: FileDirectory default - see the class side methods for details.

A FileSaverDialog is a modal dialog for choosing a file name to use for saving a file. Users can enter a filename in the text input view that will a) if it exists in the current directry listing, be selected b) over ride any filenames in the current directry, providing a way to specify a completely new file. This will not affect the selected directory path. Normal usage would be myFilename := FileSaverDialog openOn: myApplicationDefaultDirectory initialFilename: 'foo.myapp' + to find a file with a name matching foo.myapp and with the directory initial choice set to myApplicationDefaultDirectory. It would be quite possible to choose a file from any other directory and with any other name if the user wishes, so the file name must be carefully checked. The full set of options would invovle + myFilename := FileSaverDialog openOn: myApplicationDefaultDirectory initialFilename: 'foo.myapp' pattern: '*.mya' message: 'Save your myApp file to ...
