34 // This test shows a frame with four focusable components: b0, b1, b2, b3.
35 // Then it presses Tab three times. EDT is freezed for a while on the first FOCUS_LOST event.
36 // Meantime, the test clicks in a component of another frame and then clicks in the title
37 // of the original frame. When EDT awakes and all the queued events get processed,
38 // the other frame should ones gain focus and then pass it to the original frame.
39 // The b3 component of the orinial frame should finally become a focus owner.
40 // The FOCUS_LOST/FOCUS_GAINED events order in the original frame is tracked and should be:
41 // b0 -> b1 -> b2 -> b3.
