an AWT open/save File Dialog

Purpose

This enhanced Java Bean is a "fast" open/save file chooser dialog, based on the AWT system, for those who think that the Swing JFileChooser available is too "slow".

It uses the FBean package.

The Java code

     AWTFileDialog.java

The methods you can set


Register the bean

The Implementation Class is : oracle.forms.fd.AWTFileDialog

FBean.Register_Bean('CTRL.BEAN', 1, 'oracle.forms.fd.AWTFileDialog');

Open file dialog box

var := FBean.Invoke_Char('CTRL.BEAN', 1, 'openFile' ,'Open a file...,C:\,*.java');

The last argument is composed by a title, a starting directory and a file filter.
If you want to provide a file type list, separate them with a ; like the following:
var := FBean.Invoke_Char('CTRL.BEAN', 1, 'openFile' ,'Open a file...,C:\,*.jpg;*.jpeg;*.gif');

Save file dialog box

var := FBean.Invoke_Char('CTRL.BEAN', 1, 'saveFile' ,'Save file as......,C:\,filename.txt');

set debug ON/OFF

FBean.Invoke('CTRL.BEAN', 1, 'setLog' ,'true | false');

The sample dialog


     . Download the AWTFileDialog.jar file
     . Download the AWTFileDialog.fmb file
     . copy the AWTFileDialog.jar file in the <ORACLE_HOME>/forms/java directory
     . Edit your /forms/server/formsweb.cfg file to add the AWTFileDialog.jar to both archive and archive_jini tags.
     . Open the AWTFileDialog.fmb module
     . Compile all and run the module

This works so much better than the default Webutil file dialogues.  Thanks!

Just a correction based on my experiments:  to save a file as a specific name, use this syntax.  This will default the save dialog to the C: drive and a filename of 'myfilename.txt'.


var := FBean.Invoke_Char('CTRL.BEAN', 1, 'saveFile' ,'Save file as......,C:,myfilename.txt');

Hello,I posted a similar implementation based on VBean over at http://www.degenio.com/2008/12/file-selection-dialog-with-oracle-forms-10g-1012-replacing-some-of-webutil-functionalities/I choose to follow the fileuploader  demo used in Forms 10g.Now, whether the use of FileDialog over JFileChooser is warranted was not an option. With a directory that contains more than 1200 folders,  FileDialog gives a much better user experience and saved us from a number of user complaints.
