Login Form JAVA

Question

I tried to write my first code.
Was not so bad but I can't figure out why the first time that i'm writing in Password Text Box the password characters are not masked with ******.
But it happens only the first time that you write on that box.
after you check and uncheck the box one time it is running correctly.

Someone could understand why please?!?

Thank you

Here the Code:

Answer 1

Honestly I don't know this SWT tool you're using, but I was thinking maybe you can try to set textbox mask character immediately after you created the password text box.

text_1 = new Text( shell, SWT_BORDER );
text_1.setBounds( 147, 160, 164, 21 );
text_1.setEchoChar( '*' );

text_1 = new Text(shell, SWT.BORDER);

Button btnShowPassword = new Button(shell, SWT.CHECK);

// Coding Show Password Check Button

btnShowPassword.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
if(e.getSource()==btnShowPassword) {
if(btnShowPassword.getSelection()==true) {
text_1.setEchoChar((char)0);
}else {
text_1.setEchoChar('*');
}
}
}
});
btnShowPassword.setBounds(147, 237, 109, 16);
btnShowPassword.setText("Show Password");
Button btnLogin = new Button(shell, SWT.NONE);

//Coding Login Button

Answer 3

also for reset button, set echo back to *

btnReset.addSelectionListener(...)
...
if (e.getSource() == btnReset) {
text.setText("");
text_1.setText("");

text_1.setEchoChar('*'); //
btnShowPassword.setSelection(false); //
}

String pwdTxt;
userTxt=text.getText();

shell.open();
shell.layout();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
