RE: [ve-dev] Setting colors, SWT lables

[Joe Winchester <WINCHEST@xxxxxxxxxx>]

Hi Phillipe,

>label.setBackground(new
Color(Display.getDefault(),200,111,50));

SWT requires explicit disposal of colors.
 The color has to be either got from somewhere that manages it, like

setBackground(Display.getDefault().getSystemColor(SWT.COLOR_RED));

or else we need to have code like

finao Color color = new Color(Display.getDefault(),200,111,50));
control.setBackground(color);
control.addDisposeListener(new DisposeListener(){
   public void widgetDisposed(Event
e){
      color.dispose();
   }
});

or have instance variables for each
color and dispose them with the view is closed down

Best regards,

Joe

Evi:
What about using  something like:
label.setBackground(new Color(Display.getDefault(),200,111,50));
Or keeping a tab on a dislpay in a variable?

Hello!
I have tried to figure out how to set label background colors when
working with Eclipse SWT. The only advise I found was to use
"label.setBackground(new Color(display,200,111,50)); 
But in automatically created VE+SWT construct "display" is not
recognised. My code is copied below, please advise what I need to change
in order to set background colors to widgets. 
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.*;
public class StartWindow {
 private Shell sShell = null;
 private Label label = null;

 public static void main(String[] args) {

  Display display = Display.getDefault();
  StartWindow thisClass = new StartWindow();
  thisClass.createSShell();
  thisClass.sShell.open();
  while (!thisClass.sShell.isDisposed()) {
   if (!display.readAndDispatch())
    display.sleep();
  }
  display.dispose();
 }
 /**
  * This method initializes sShell
  */
 private void createSShell() {
  sShell = new Shell();
  sShell.setText("Shell");
  sShell.setSize(new Point(300, 200));
  sShell.setLayout(new GridLayout());
  label = new Label(sShell, SWT.NONE);
  label.setText("labellabellabel");
  label.setBackground(new Color(display,200,111,50));
 }
}
Regards,
Evi
