Re: [platform-ui-dev] Eclipse view plugin: swing problem

[Eric Moffatt <emoffatt@xxxxxxxxxx>]

Benoit, the purposre of the view's 'setFoxus'
method is to allow the person implmenting the view to set the keyboard
focus to the correct control when the view is activated. In most cases
it sets the focus to its 'main' control (for us this is usually the 'tree'
contained in the view). I'm not an AWT user but it surely has some mechanism
to 'focus' the keyboard..

try this....

    public void setFocus() {
        swtAwtComponent.setFocus(); // Presumes
that AWT composites have a 'setFocus'
        frame.setFoxus();
// or perhaps this if AWT composites do -not- support 'setFocus'
    }


Let me know if this helps...

Thank you Boris,

I will take your advice and post to the eclipse.plateform group. But just
in case someone here would have a quick answer for me, I will post more
details.

Running
Windows Vista 32bit
Java 1.6
Eclipse 3.4.0

You are absolutly correct, my setFocus() method was empty. I started off
with a sample project and stripped off all of the useless stuff out of
it (apparently I took too much off). I tryed to set the focus. But i dont
seem to be able to know to what. I will include a complete code snippet
if it may help.

package ftie.views;

import javax.swing.*;

import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.part.*;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.ui.*;
import org.eclipse.swt.SWT;


public class FtieView extends ViewPart {

    Composite swtAwtComponent;
    java.awt.Frame frame;
    Ftie_ui ui;

    public FtieView() {
    }

    public void createPartControl(Composite parent) {
        try{
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
        }catch (Exception e){
            //TODO: manage exception
        }
        
        swtAwtComponent = new Composite(parent, SWT.EMBEDDED);
        frame = SWT_AWT.new_Frame( swtAwtComponent
); 
        ui = new Ftie_ui();
        frame.add(ui);

    }


    public void setFocus() {

    }
}



package ftie.views;

import javax.swing.*;

public class Ftie_ui extends JPanel{

    JLabel labelUser;
    JLabel labelPass;
    JTextField txtUser;
    JPasswordField txtPass;
    JButton btnLogin;
    
    
    public Ftie_ui()
    {
        //TODO: add layout
        
        labelUser = new JLabel();
        labelUser.setText("Username:");
        
        labelPass = new JLabel();
        labelPass.setText("Password:");
        
        txtUser = new JTextField(20);
        txtUser.setEditable(true);
        txtUser.setEnabled(true);
        
        txtPass = new JPasswordField(20);

        btnLogin = new JButton("Login");
        
        add(labelUser);
        add(labelPass);
        add(txtUser);
        add(txtPass);
        add(btnLogin);
    }
}

The second best place would be a bug report.

My guess would be that you did not implement your part's setFocus()
method, but it is hard to tell without a complete code snippet, and
without knowing the platform (Windows? GTK? Mac/Carbon?) and the
Eclipse version (3.3? 3.4?).
