How to select multiple files and/or folders at the same time in a GUI by using SWT?

Given that you've put only Java as a tag, but given that I know zero about SWT, in Java a file can be both a file, or a directory, so this ought to be the first thing to check - that you are in fact not seeing both already.

this piece of code will do the work:

} else if (toolItem == Gui.item111) {
                  FileDialog fd = new FileDialog(shell, SWT.MULTI);
                  String firstFile = fd.open();
                  if (firstFile != null) {
                        String[] selectedFiles = fd.getFileNames();
                        for (int ii = 0; ii < selectedFiles.length; ii++ ) {
                              System.out.println("selected file : " + selectedFiles[ii]);
                        }
                  }
            }

So, now I have this piece of code with the addition of your suggestion and with this code, I cannot select the files  and the folders by using the same icon.

What it does is, it selects the folders because the DirectoryDialog is before the FileDialog in the if statement.

If I remove this piece of if statement then the new code that you suggested can only select multiple files but not the folders.

This is the code I have:

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.DirectoryDialog;
import org.eclipse.swt.widgets.FileDialog;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.widgets.Listener;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.ToolItem;


public class ToolBarListener implements Listener {
    
    private Shell shell;

    @Override
    public void handleEvent(Event event) {
        ToolItem toolItem = (ToolItem) event.widget;
        if (toolItem == Gui.item1) {
            System.out.println("item1 clicked...");
            DirectoryDialog dlg = new DirectoryDialog(shell);
            String dir = dlg.open();
            System.out.println("chosen dir : " + dir);
        } else if (toolItem == Gui.item13) {
            Gui.swichTabChecks();
        } else if (toolItem == Gui.item23) {
            Gui.swichTabResults();
        } else if (toolItem == Gui.item3333333) {
            Gui.swichTabFiles();
        } else if (toolItem == Gui.item1) {
            FileDialog fd = new FileDialog(shell, SWT.MULTI);
            String firstFile = fd.open();
            if (firstFile != null) {
                  String[] selectedFiles = fd.getFileNames();
                  for (int ii = 0; ii < selectedFiles.length; ii++ ) {
                        System.out.println("selected file : " + selectedFiles[ii]);
                  }
            }
      } 
    }

    public void setShell(Shell shell) {
        this.shell = shell;
    }

}

Select all Open in new window

My requirement is to select multiple files and/or directories by using the same icon. Also, files and directories should be selected at the same time in one shot.

So as an example, I have the following files and folders in directory A.

dirA
   dir1
   dir2
   dir3
   fileX
   fileY
   fileZ

Select all Open in new window

I should be able to select the following files and folders in dirA directory in one shot by using the same icon on the UI:

dir1
dir3
fileY
fileZ

Select all Open in new window

I would appreciate if you can help me with that.

Thanks,

You can't do this with standart SWT widgets. There are only file dialog and directory dialog.
You need to develop your own custom widget.
I found exactly what you need here:

Hi,
Thank you for your reply. Can you please tell me in more detail how I will use the cod that you sent me in the link?

Currently, this is the code that I use to select directories. How should I change this code/

   

     if (toolItem == Gui.item1) {
            System.out.println("item1 clicked...");
            DirectoryDialog dlg = new DirectoryDialog(shell);
            String dir = dlg.open();
            System.out.println("chosen dir : " + dir);

Hi Valeri,
If you have time, can you please take a look at my other questions?

Thanks,

Hi Valeri,
I created the file you sent me, FileTree.java.

I added the following line to ToolBarListener.java:

        if (toolItem == Gui.item1) {
            Gui.selectFileFolders();
        }

Select all Open in new window

I added this listener in Gui.java:
       

item1.addListener(SWT.Selection, toolBarListener);

Select all Open in new window

Then I created this function in Gui.java:

    public static void selectFileFolders() {
        
    } 

Select all Open in new window

But I don't know what to write in it.

Can you please help?

@Valeri: I can open a new email thread if you prefer.
