ok. thanks for t he clarification. One point however, in spec it is
mentioned to use "As of v1.3, it is recommended that developers call
|Component.AccessibleAWTComponent.getAccessibleChild()| instead of this"
getAccessibleChild(JComponent c,
int i)

Hi Prasanta,

This fix is not specific to any particular scale factor. I have just
modified it to work independent of the fact popup is created above or
below. This change is independent of any HiDPI settings. Using HiDPi
scale >= 2 is just one of reproducing this issue. It can be reproduced
altering the window size, changing number of items in popUp etc.
basically the test case should not assume that popup will be opaque
always when there are scenarios, when it won’t be opaque.
<< If not, I think it should be alright to restrict the testcase to
run with uiScale=1.0 as it is not testing any hidpi feature.
I found this issue while working on a bug
https://bugs.openjdk.java.net/browse/JDK-8164811, which involves using
translucent components with HiDPI screens and that issue was found
because of this test case only. So I think this test case is supposed
to work well on HiDPI screens. All the test cases in the same folder
are run on 1.5 scale by default.

Hi Pankaj,
Copyright year should contain only the initial creation year and
latest year in which the change is made. So you should replace
2016 with 2018. No need for another webrev you can make that
change while pushing.
Other changes present in webrev.01 over webrev.00 is fine.
Please wait for more inputs from others before pushing the change.
Thanks,
Jay

Hello Jay,
Thanks for the review.

Done.

No, it will not work. “popup.getLocationOnScreen().y > ls.y” is
required to find whether the popup is created above or below the
JComboBox.
If it is below, raise exception as color conditions should have
passed and this is an issue
If it is above, then we further need to verify, if it will fit
inside the window or not. If it does not fit, then popup will be
opaque and raise exception as color test should have passed.
Here we are trying to be sure that when the test has failed, it
was not because of the reason that popup was translucent. In case
of translucent popup, the color test will not pass and exception
should not be thrown as it is expected.
<<Also I remember we discussed on call that if possible we can

space below the window giving test more chance to <<execute properly.
All that was required assuming that we can’t find if the popup is
created below or above the JComboBox. But I was able to find that
using the popup and JComboBox location and this change is no
longer needed.

Hi Pankaj,
Please find my input:

& it’s better to keep jtreg comments before code for program
starts like import statements.
I think any one condition out of “(popup.getLocationOnScreen().y >
ls.y” & “window.getHeight() < popup.getHeight() +
south.getHeight()” would be enough to verify if popup.y exceeds
window.y or not.
Also I remember we discussed on call that if possible we can keep
the main window starting at y = 0, so that we have enough space
below the window giving test more chance to execute properly.
Thanks,
Jay

Hi All,
Please review the test only fix for JDK 11.
Bug:
https://bugs.openjdk.java.net/browse/JDK-8190347
webrev:
http://cr.openjdk.java.net/~pbansal/8190347/webrev.00/
<http://cr.openjdk.java.net/%7Epbansal/8190347/webrev.00/>
Issue:
The test TranslucentJComboBox creates a Translucent JWindow and
then adds a JComboBox at the bottom. Then a popup is created when
clicked on JComboBox. The test always checks the popup for
opaqueness whether it is created below or above the JComboBox. If
it is created below the JComboBox, it will be opaque. If it is
created above the JComboBox and it does not fit within the JWindow
containing JComboBox, it will be opaque.
But in some scenarios, the Popup is created above the JComboBox
and it can fit within the JWindow. In this case, it be translucent
and the test will fail. The test needs to consider these scenarios.
One of the scenario to reproduce this is to run this test on a
1920X1080 screen with HiDPI value 2.0. The popup will be created
above and it will fit within the JWindow of size 500X500. The test
fails.
Fix:
Made changes to check if the popup is created below or above the
JComboBox when the color values don’t pass the conditions. If it
is created below or if it is created above and If it does not fit,
through the exception else ignore.

Pankaj Bansal
