17. 2. 12. Get Preferred size

(From SWT API) The preferred size of a control is the size that it would best be displayed at. The width hint and height hint arguments allow the caller to ask a control questions such as "Given a particular width, how high does the control need to be to show all of the contents?" To indicate that the caller does not wish to constrain a particular dimension, the constant SWT.DEFAULT is passed for the hint.


import org.eclipse.swt.SWT;

import org.eclipse.swt.layout.GridLayout;

import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Shell;



public class GetPreferredSize {



  public static void main(String[] args) {

    final Display display = new Display();

    Shell shell = new Shell(display);



    shell.setLayout(new GridLayout());



    Button button = new Button(shell, SWT.PUSH | SWT.LEFT);

    button.setText("Button");



    System.out.println("toControl: " + button.toControl(100, 200));



    shell.open();

    while (!shell.isDisposed()) {

      if (!display.readAndDispatch()) {

        display.sleep();

      }

    }

  }

}
