18.22 java.awt.FileDialog (JDK 1.0)

This class represents a file selection dialog box. The constants LOAD and SAVE are values of an optional constructor argument that specifies whether the dialog should be an Open File dialog or a Save As dialog. You may specify a FilenameFilter object to control which files are displayed in the dialog.

The inherited show() method pops the dialog up. For dialogs of this type, show() blocks, not returning until the user has selected a file and dismissed the dialog (which pops down automatically--you don't have to call hide()). Once show() has returned, use getFile() to get the name of the file the user selected.

public class FileDialog extends Dialog {
    // Public Constructors
        1.1  public FileDialog(Frame parent);
            public FileDialog(Frame parent, String title);
            public FileDialog(Frame parent, String title, int mode);
    // Constants
            public static final int LOAD;
            public static final int SAVE;
    // Public Instance Methods
            public void addNotify();  // Overrides Dialog
            public String getDirectory();
            public String getFile();
            public FilenameFilter getFilenameFilter();
            public int getMode();
            public synchronized void setDirectory(String dir);
            public synchronized void setFile(String file);
            public synchronized void setFilenameFilter(FilenameFilter filter);
        1.1  public void setMode(int mode);
    // Protected Instance Methods
            protected String paramString();  // Overrides Dialog
