Failed to create widget reference for instance of org.eclipse.swt.widgets.Slider WindowTester: 201009131510 - win32,win32,x86

[Phillip Jensen]

Hi,

I am using Win XP, Eclipse 3.6.1, WT 6.0.0.

We have a composite that has some widgets including a Slider and a
Label. We are asserting text on the label like this:

ui.assertThat(new
NamedWidgetLocator("positionLabel").hasText("..."));

We are seeing this exception:

Could you post the test code? Also if you have a snippet that can be
used to reproduce this problem at our end, it would be very helpful.

[Phillip Jensen]

See attached zip.  It contains an eclipse project with a simple view and a window tester test that causes the exception.

[keertip]

Thanks Phil! We will take a look.

We were able to reproduce this, thanks to your sample test. The issue
here is with the Slider widget. If you comment out the Slider, the
test should run fine.
We'll look into why WindowTester does not recognize the Slider widget.

Any news on this issue?

I also experience the problem and it would be of great value for my
tests to be able to work with slider widgets.

I just posted a patch for WT to add support for the Slider widget.  See Issue 10 (https://code.google.com/p/windowtester/issues/detail?id=10).
