SWT 文本小部件不显示

Question

package org.jilen.editor
import org.eclipse.swt.widgets.Display
import org.eclipse.swt.widgets.Shell
import org.eclipse.swt.widgets.Text
import org.eclipse.swt.SWT

object EditorApp {
  def main(args: Array[String]) {
    val display = new Display()
    val shell = new Shell(display)
    val text = new Text(shell, SWT.CENTER)
    text.setText("Hello SWT")
    shell.pack()
    shell.open()
    while (!shell.isDisposed) {
      if (!display.readAndDispatch) {
        display.sleep()
      }
    }
    display.dispose()
  }
}

extremely simple code, but no text is show.
The window should have "hello swt" in the center.

Add this line after creating your shell:

shell.setLayout(new FillLayout)
