SWT: FontDialog

By using FontDialog, user can select a font from fonts available in the system.

Ex:

FontData defaultFontData = new FontData("Courier", 12, SWT.ITALIC);

FontData[] fontList = { defaultFontData };

FontDialog fontDialog = new FontDialog(shell, SWT.NONE);

fontDialog.setText("FontDialog Demo");

fontDialog.setRGB(new RGB(0, 0, 255));

fontDialog.setFontList(fontList);

FontData fontData = fontDialog.open();

Following is the complete working application.

import java.util.Objects;

import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.FontData;
import org.eclipse.swt.graphics.RGB;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.FontDialog;
import org.eclipse.swt.widgets.Shell;

public class Test {

 private static void addWidgetsToShell(Display display, Shell shell) {
  FontData defaultFontData = new FontData("Courier", 12, SWT.ITALIC);
  FontData[] fontList = { defaultFontData };
  FontDialog fontDialog = new FontDialog(shell, SWT.NONE);
  fontDialog.setText("FontDialog Demo");
  fontDialog.setRGB(new RGB(0, 0, 255));
  fontDialog.setFontList(fontList);
  FontData fontData = fontDialog.open();

  if (!Objects.isNull(fontData)) {
   System.out.println("Font Name Selected:" + fontData.getName());
   System.out.println("Font Height Selected:" + fontData.getHeight());
   System.out.println("Font Style Selected:" + fontData.getStyle());
   System.out.println("Font Colour Selected:" + fontDialog.getRGB());
  }
  shell.dispose();
 }

 public static void main(String[] args) {

  /* Instantiate Display object, it represents SWT session */
  Display display = new Display();

  /*
   * Define Shell, it represent a window, You can add more than one shell
   * to Display
   */
  Shell shell = new Shell(display);
  shell.setSize(500, 500);
  addWidgetsToShell(display, shell);

  /*
   * Run the event dispatching loop until an exit condition occurs, which
   * is typically when the main shell window is closed by the user.
   */

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

  /* Dispose the display */
  display.dispose();

 }
}
