Problem with Listbox

[qualitystreet]

Hi,

I have a gui window that I want to be able to load items into a Listbox from a CSV file.

If I create another class to read the text file and load it into an array, how can I them add the items to the ListBox on the form?

Do I need some sort of Listner?

Thanks



import org.eclipse.swt.widgets.Display;

public class guiwindow {

protected Shell shell;

/**
* Launch the application.
* @param args
*/
public static void main(String[] args) {
try {
guiwindow window = new guiwindow();
window.open();
} catch (Exception e) {
e.printStackTrace();
}
}

/**
* Open the window.
*/
public void open() {
Display display = Display.getDefault();
createContents();
shell.open();
shell.layout();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
}

/**
* Create contents of the window.
*/
protected void createContents() {
shell = new Shell();
shell.setSize(450, 300);
shell.setText("SWT Application");

List lstItems = new List(shell, SWT.BORDER);
lstItems.setBounds(10, 10, 197, 242);

Button btnLoadFile = new Button(shell, SWT.NONE);
btnLoadFile.addMouseListener(new MouseAdapter() {
@Override
public void mouseUp(MouseEvent e) {
//run import from csv here
}
});
btnLoadFile.setBounds(220, 10, 75, 25);
btnLoadFile.setText("Load File");

}

}

To fix it I had to declare my listbox as a public in the class,


public class guiwindow {

protected Shell shell;
public List lstItems;

/**
* Launch the application.
* @param args
*/
public static void main(String[] args) {
try {
guiwindow window = new guiwindow();
window.open();
} catch (Exception e) {
e.printStackTrace();
}
}

/**
* Open the window.
*/
public void open() {
Display display = Display.getDefault();
createContents();
shell.open();
shell.layout();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
}

/**
* Create contents of the window.
*/
protected void createContents() {
shell = new Shell();
shell.setSize(450, 300);
shell.setText("SWT Application");

lstItems = new List(shell, SWT.BORDER);
lstItems.setBounds(10, 10, 197, 242);

Button btnLoadFile = new Button(shell, SWT.NONE);
btnLoadFile.addMouseListener(new MouseAdapter() {
@Override
public void mouseUp(MouseEvent e) {
//run import from csv here
}
});
btnLoadFile.setBounds(220, 10, 75, 25);
btnLoadFile.setText("Load File");

}

}
