Swing widgets embedded within SWT widgets

[Chin-Huat Ang]

Please forgive me if this is a duplicate post, I tried searching the whole forum but I couldn't find any topic similar to this one.

I have the following code in an Eclipse plugin which makes embedding Swing widgets in SWT possible, using SWT/AWT bridge:

Code: Select all

      
Composite container = new Composite(parentComposite, SWT.EMBEDDED | SWT.NO_BACKGROUND);
Frame frame = SWT_AWT.new_Frame(container);
JApplet applet = new JApplet();
// Populate applet with Swing widgets
frame.add(applet);


The result of this code snippet shows Swing widgets nicely in an SWT container, all the keyboard and mouse events are properly handled and dispatched to the embedded Swing widgets. The questions, is it possible to test this? I'm using Window Tester Pro v3.5.0 for Eclipse 3.4, running the test as JUnit plugin test.The problem is when I try to record an Eclipse application launch, it'll only generate codes related to locating SWT widgets. I tried to use Swing widget locators within the SWT test case and I get widget not found exception instead.

Code: Select all

public class TestLaunch extends UITestCaseSWT {

   public void testTestLaunch() throws Exception {
      IUIContext ui = getUI();
      ui.click(new MenuItemLocator("File/New/Other..."));
      ui.wait(new ShellShowingCondition("New"));
      ui.click(new FilteredTreeItemLocator("My wizard"));
      ui.click(new ButtonLocator("&Next >"));
      ui.click(new JRadioButtonLocator("Option one"));  // <--- *** Swing widget locator ***
      ui.click(new ButtonLocator("&Next >"));
      ui.enterText("test");
      ui.click(new ButtonLocator("Cancel"));
   }
}


From the stack trace, it appears that the exception was thrown from within SWT UI context.

Code: Select all

Any help would be greatly appreciated.

Do you have a simple sample we could use to reproduce this on our end? We'll make much faster progress with a local reproduction.

Thanks!

Is testing embedded swing widgets within SWT widgets supported under Window Tester Pro?

[Phil Quitslund]

It is not supported in the recorder but should be possible in the runtime. In other words you should be able to hand write tests that work with embedded Swing components even if they are not recognized by the recorder. If anyone can volunteer a simple sample app or snippet, we can cook up some examples... Thanks!

[samtonyclarke]

We are currently evaluating using TesterPro to test embedded swing widgets nested with and swt widget. An example would be much appreciated, even if it is just for run time playback. Is recording nested swing events on the road map?

[Phil Quitslund]

Hybrid recording is on the short list but not yet scheduled. As for a sample, do you have a stand-alone example we could build a test around? Perhaps something based on one of the SWT snippets here?:
