swt shell 和组件的最小尺寸

Question

How can I set a minimum size of the shell in swt? For example I have added a search field in my shell but I can shrink the shell almost completely and then the search field isn't completely visible. Can I change a property of the search field to stop resizing if it would be unseen?

Answer 1

No, there isn't any property or anything like that to prevent the resizing.

About the only thing you can do is add a resize listener to the shell and stop the resize if the shell is too small:

shell.addListener(SWT.Resize, event -> {
  Shell eventShell = (Shell)event.widget;

  Point size = eventShell.getSize();

  if (size.x < 100 || size.y < 100)
   {
     // Stop the resize event
     event.doit = false;
   }
});
