Compare StyleRange : StyledText Style « SWT « Java Tutorial






similarTo(), compares the display data for two StyleRange objects for equality: the foreground color, the background color, and the font style. It ignores which portion of the text the StyleRanges correspond to (their start and length fields).

import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.StyleRange;
import org.eclipse.swt.custom.StyledText;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class CompareStyleRange {
  public static void main(String[] args) {
    final Display display = new Display();
    final Shell shell = new Shell(display);

    final StyledText styledText = new StyledText(shell, SWT.V_SCROLL | SWT.BORDER);
    styledText.setText("12345");

    // Use the empty constructor and set the fields
    StyleRange sr1 = new StyleRange();
    sr1.start = 7;
    sr1.length = 14;
    sr1.foreground = display.getSystemColor(SWT.COLOR_GREEN);
    sr1.background = display.getSystemColor(SWT.COLOR_WHITE);
    sr1.fontStyle = SWT.BOLD;

    // Use the constructor that accepts the fields
    StyleRange sr2 = new StyleRange(7, 14, display.getSystemColor(SWT.COLOR_GREEN), display
        .getSystemColor(SWT.COLOR_WHITE), SWT.BOLD);

    
    System.out.println(sr2.similarTo(sr1));
    
    
    styledText.setBounds(10, 10, 100, 100);
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch()) {
        display.sleep();
      }
    }
    display.dispose();
  }
}
