Hi Everyone,
I would like to create Username and password window to provide a basic auth to my app, I created the GUI for it (look below), however I am not sure where shall I call it (Application.java?) and how to start up the application if the username and the password is right!?
package net.dresdnerkleinwort.hierarchy.client;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
public class UserPassword {
Display display = new Display();
Shell shell = new Shell(display);
Text textUser;
Text textPassword;
private void init() {
(new Label(shell, SWT.NULL)).setText("User name: ");
textUser = new Text(shell, SWT.SINGLE | SWT.BORDER);
textUser.setText("default_user");
textUser.setTextLimit(16);
(new Label(shell, SWT.NULL)).setText("Password: ");
textPassword = new Text(shell, SWT.SINGLE | SWT.BORDER);
System.out.println(textPassword.getEchoChar());
textPassword.setEchoChar('*');
}
public UserPassword() {
shell.setLayout(new GridLayout(2, false));
shell.setText("Hierarchy Manager Login");
init();
textUser.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
textPassword.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
shell.pack();
shell.setSize(280, 100);
shell.open();
//textUser.forceFocus();
// Set up the event loop.
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
// If no more entries in event queue
display.sleep();
}
}
display.dispose();
}
public static void main(String[] args) {
new UserPassword();
}
}

Ali,
I'm doing this in one of my own applications. In my application, I have
to check for a valid license to the software right at startup. I
extended ApplicationWindow from JFace for my main window, and added a
SWT.Activate listener to the shell in the configureShell(Shell) method:
shell.addListener(SWT.Activate, new Listener() {
public void handleEvent(Event event) {
License license = getProductLicense();
if (license == null || !license.isActive()) {
license = showLicenseDialog();
if (license == null || !license.isActive())
shell.close();
}
}
});
I have some more stuff in there that warns the user when the software
will expire, but you get the basic idea. This code will run every time
the window is activated (which happens when the window first appears,
and again every time you leave the window and return to it).
Another option is to prompt for the user's credentials before the main
window ever appears, probably right before calling shell.open() on your
main window. Does this help?

Hi,
I call my login dialog in the postWindowOpen method of my application's
WorkbenchWindowAdvisor. That way, it is show after the workbench is opened.
Here is my code:
public void postWindowOpen() {
super.postWindowOpen();
/* Hide the splash screen*/
Platform.endSplash();
/* Show the login dialog */
showLogin();
}
The dialog is a modal dialog.
Regards,
Camilo.
