JfileChooser Help

[simmi]

Hi All,

I am using JfileChooser.I have OK button for approval.I want to make a check that when i click on OK button it checks for some condition and if that condition is true then only file chooser window should close.But as Approve option is on OK button everytime i click OK file chooser window gets close.

Could you please tell me how to put that check.

public File createFileSelectionBox(){
fileSelectionDialog = new JFileChooser();
fileSelectionDialog.setDialogTitle ("FileSelectionBox");
// Choose only files, not directories
fileSelectionDialog.setFileSelectionMode ( JFileChooser.FILES_AND_DIRECTORIES);
int result = fileSelectionDialog.showDialog(null,"OK");
if (result == JFileChooser.CANCEL_OPTION) {
return null;
} else if (result == JFileChooser.APPROVE_OPTION) {
file = fileSelectionDialog.getSelectedFile ();
}
return file;
}

Thanks in Advance,
Simmi

This could be one of the ways, but there might be better ways too

public File createFileSelectionBox(){
		JFileChooser fileSelectionDialog = new JFileChooser();
		fileSelectionDialog.setDialogTitle ("FileSelectionBox");
		File file=null;
		// Choose only files, not directories
		fileSelectionDialog.setFileSelectionMode ( JFileChooser.FILES_AND_DIRECTORIES);
		int result = fileSelectionDialog.showDialog(null,"OK");
		if (result == JFileChooser.CANCEL_OPTION) {
			return null;
		} else if (result == JFileChooser.APPROVE_OPTION) {
			file = fileSelectionDialog.getSelectedFile ();
                        //if the selected file is not gif, we once again call the method
			if(!file.getName().endsWith("gif")){
				createFileSelectionBox();
			}
		}
		return file;
	}

Thanks dswastik.
I have one more issue. I want whenever I open jfilechooser the current directory should get displayed in fileName.

I tried with
fileSelectionDialog = new JFileChooser(new File("."));
But it didnot work.In the begining it is still blank.
What needs to be done.

Thanks Simmi.

What you are doing should work, and even if use the no-arg constructor it should not be blank, it should display the user's default directory, which is typically My Documents in windows.

[dswastik]

Well, probably there is a small confusion. The directory can be displayed in the look in drop down. But how can you display a directory name in the File Name text box, I guess it can always be a file name?

[simmi]

Actually I have used setFileSelectionMode ( JFileChooser.FILES_AND_DIRECTORIES), if I choose setFileSelectionMode ( JFileChooser.DIRECTORIES_ONLY) then it display current directory in the text box.
So is there any way to display current directory in file Text when mode is JFileChooser.FILES_AND_DIRECTORIES.

Thanks,
Simmi

After setting the selection mode, you can try this

fileSelectionDialog.setSelectedFile method

[dswastik]

But the point is that text field is used to display the selected file. Any where if you click file open (ms-word,excel) that displays the selected file name with the complete path. Why do you have such a requirement?

[simmi]

Ya Thats right.But i needed to get the absolute path of the selected file.
But now i dont need it.

Thanks alot.:)

From a "File" object you can get the absolute path among other things.
