| FileDialog | | public class FileDialog extends Dialog (Code) | | The FileDialog class displays a dialog window
from which the user can select a file.
Since it is a modal dialog, when the application calls
its show method to display the dialog,
it blocks the rest of the application until the user has
chosen a file.

SAVE. |
| Constructor Summary | |
| public | FileDialog(Frame parent)
Creates a file dialog for loading a file. | | public | FileDialog(Frame parent, String title)
Creates a file dialog window with the specified title for loading
a file. | | public | FileDialog(Frame parent, String title, int mode)

| addNotify | | public void addNotify()(Code) | | Creates the file dialog's peer. The peer allows us to change the look
of the file dialog without changing its functionality.
|
| constructComponentName | | String constructComponentName()(Code) | | Construct a name for this component. Called by getName() when the
name is null.
|
| getFile | | public String getFile()(Code) | | Gets the selected file of this file dialog.
the currently selected file of this file dialog window,or null if none is selected.
See Also: java.awt.FileDialog.setFile |
| getFilenameFilter | | public FilenameFilter getFilenameFilter()(Code) | | Determines this file dialog's filename filter. A filename filter
allows the user to specify which files appear in the file dialog
window. Filename filters do not function in Sun's reference
implementation for Windows 95, 98, or NT 4.0.
this file dialog's filename filter.

See Also: java.awt.FileDialog.setFilenameFilter |
| paramString | | protected String paramString()(Code) | | Returns the parameter string representing the state of this file
dialog window. This string is useful for debugging.
the parameter string of this file dialog window. |
| postsOldMouseEvents | | boolean postsOldMouseEvents()(Code) | | |
| setDirectory | | public void setDirectory(String dir)(Code) | | Sets the directory of this file dialog window to be the
specified directory. Specifying a null or an
invalid directory implies an implementation-defined default.
This default will not be realized, however, until the user
has selected a file. Until this point, getDirectory()
will return the value passed into this method.
Specifying "" as the directory is exactly equivalent to
specifying null as the directory.
Parameters:
dir - the specific directory.
See Also: java.awt.FileDialog.getDirectory |
| setFile | | public void setFile(String file)(Code) | | Sets the selected file for this file dialog window to be the
specified file. This file becomes the default file if it is set
before the file dialog window is first shown. Specifying "" as
the file is exactly equivalent to specifying null
as the file.
Parameters:
file - the file being set.
