Hi Armin - thank you, but that result was the same. Here is the code snippet
I am using.
--- cut here ---
package UI;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Button;
public class PB_xxx implements INTERFACES.IF {
public static void main(String[] args) {
new PB_xxx().runTHIS(new String[] { });
}
void runTHIS(String[] args) {
Display display = new Display();
final Shell shell = new Shell(display);
shell.setSize(395,80);
final Button btnCAS = new Button(shell, SWT.NONE);
btnCAS.setSelection(true);
btnCAS.setText("Contracting Administration Screen");
btnCAS.setForeground(Display.getCurrent().getSystemColor(SWT .COLOR_RED));
btnCAS.setBackground(Display.getCurrent().getSystemColor(SWT .COLOR_RED));
// left,top,width,height
btnCAS.setBounds(10, 10, 360, 30);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
}
}
--- end ---
