I have proven your code, but it does not work for me. I have noticed, that
if I do not set the width of the separator, the label is visible. Here you
have an snippet:
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.graphics.GC;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.ToolBar;
import org.eclipse.swt.widgets.ToolItem;
public class ToolBarSeparator {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
ToolBar bar = new ToolBar(shell, SWT.BORDER);
for (int i = 0; i < 4; i++) {
ToolItem item = new ToolItem(bar, 0);
item.setText("Item " + i);
}
Image image = new Image(display, 10, 23);
Color color = display.getSystemColor(SWT.COLOR_RED);
GC gc = new GC(image);
gc.setBackground(color);
gc.fillRectangle(image.getBounds());
gc.dispose();
ToolItem sep = new ToolItem(bar, SWT.SEPARATOR);
int start = bar.getItemCount();
Label c = new Label(bar, SWT.READ_ONLY);
c.setText("Label");
c.pack();
sep.setWidth(c.getSize().x);//comment this line, to view the label
sep.setControl(c);
for (int i = start; i < start + 4; i++) {
ToolItem item = new ToolItem(bar, 0);
item.setText("Item " + i);
item.setImage(image);
}
bar.pack();
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
image.dispose();
}
}
