  66         UIManager.setLookAndFeel("com.sun.java.swing.plaf.gtk.GTKLookAndFeel");

I think it would be better here to do something like what we have
in javax/swing/JComboBox/7082443/bug7082443.java
Eg :

    public static final String GTK_LAF_CLASS = "GTKLookAndFeel";
        for (UIManager.LookAndFeelInfo lookAndFeelInfo : UIManager.getInstalledLookAndFeels()) {
            if (lookAndFeelInfo.getClassName().contains(GTK_LAF_CLASS)) {
                try {
                    UIManager.setLookAndFeel(lookAndFeelInfo.getClassName());
                } catch (final UnsupportedLookAndFeelException ignored) {
                    return; // can't instantiate, so not a scenario to test ?
                }

Hi Pankaj,

Some comments about the test:

I guess since we are testing for Platform.isLinux() in the test, there's no need of "requires" tag. But, I think it's better to use 

System.getProperty("os.name") so that this test can be run in standalone mode also(without using Platform class), otherwise it needs to be run in conjunction with jtreg(in which case @requires tag is better)

Also, I guess it will be good if you use UIManager.setLookAndFeel(...GtkLookAndFeel..) instead of passing through command line as user who is running standalone may forget to test in GTKL&F

Also, you are not disposing the frame if it times out so the instruction frame will linger even when the test fails.

Regards

Prasanta

Hello Prasanta/Phil/Sergey,

<<1) I suppose this fix is for 14, not 13.

Yes, that was by mistake. I am not changes the subject line, as this would create separate mail thread. This will be pushed to 14 only.
2) It is "OL", not "OEL"

Ok.
3) Can we create a reliable automated test for this ? If not we should at least create a manual one.

Done. I have added a manual test case.
4) A separate issue but we should consider adding a JSpinner demo to SwingSet2

Yes, I was also thinking that we should do it. Do we need separate approvals for changing the demos. I mean approval from some place other than swing-dev like demo team etc.

<< Does it mean that this is the behavior of the gtk3 native spinner component?

Yes, this behavior happens in native spinner. This change makes our Spinner much more similar to native gtk3 spinner

It works for oel8 too. So the fix looks fine to me.

Hi Pankaj,

I can see the issue resolved in ubuntu18.04 but not in OEL8. Also, SwingSet2 does not have JSpinner demo so we cannot put noreg-demo in JBS, so we probably need a regression test, even manual, for this.

Hi All,

Please review the following fix for jdk14.

Bug: 

https://bugs.openjdk.java.net/browse/JDK-8234733

webrev:

HYPERLINK "http://cr.openjdk.java.net/%7Epbansal/8234733/webrev00/"http://cr.openjdk.java.net/~pbansal/8234733/webrev00/

Issue:

In GTKL&F, the spinner's up/down buttons are drawn in same way whether the button is pressed or not. We can't distinguish visually whether a button is pressed or not. The buttons should be highlighted when they are in pressed state. The issue is due to style and theme changes done in gtk3 in version gtk3.20.

Fix:

The fix sets the style properly when drawing the spinner buttons with gtk3.20 or higher. All works as it is if the gtk3 version is lower than gtk3.20. The current fix is in continuity of the fixes done for issues like https://bugs.openjdk.java.net/browse/JDK-8218469

Testing:

The fix can be verified by running SwingSet2 or any other demo/sample of JSpinner (one is attached in the JBS) and it has to be verified manually. I have verified this on Ubuntu 18.04, 19.04, 19.10 and OEL 7.5. The issue is solved on all platforms.

Regards,
Pankaj Bansal
