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