SWT(JFace) 体验之FontRegistry

代码如下:

package swt_jface.demo;
import org.eclipse.jface.resource.FontRegistry;
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.FontData;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
public class FontRegistryExample {
Display display = new Display();
Shell shell = new Shell(display);

FontRegistry fontRegistry;
public FontRegistryExample() {

init();
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
private void init() {

shell.setLayout(new GridLayout(2, false));

fontRegistry = new FontRegistry(display);

fontRegistry.put("button-text", new FontData[]{new FontData("Arial", 9, SWT.BOLD)} );
fontRegistry.put("code", new FontData[]{new FontData("Courier New", 10, SWT.NORMAL)});

Text text = new Text(shell, SWT.MULTI | SWT.BORDER | SWT.WRAP);
text.setFont(fontRegistry.get("code"));
text.setForeground(display.getSystemColor(SWT.COLOR_BLUE));
text.setText("public static void main() {\n\tSystem.out.println(\"Hello\"); \n}");
GridData gd = new GridData(GridData.FILL_BOTH);
gd.horizontalSpan = 2;
text.setLayoutData(gd);

Button executeButton = new Button(shell, SWT.PUSH);
executeButton.setText("Execute");
executeButton.setFont(fontRegistry.get("button-text"));

Button cancelButton = new Button(shell, SWT.PUSH);
cancelButton.setText("Cancel");
cancelButton.setFont(fontRegistry.get("button-text"));
}
public static void main(String[] args) {
new FontRegistryExample();
}
}
