This defines a new class "DialogOwner" implementing PrintRequestAttribute
which allows an application to specify that a Print or Page dialog be
one of
1) owned by an application specified AWT window
2) owned by an application specified foreign (non-AWT) window
3) use AWT's alwaysOnTop functionality where supported.
JDK bug: https://bugs.openjdk.java.net/browse/JDK-8203796
CSR : https://bugs.openjdk.java.net/browse/JDK-8203834
JDK webrev : http://cr.openjdk.java.net/~prr/8203796/
Please review the webrev and the CSR.
The webrev will show that this functionality was already mostly
available but only as internal API.
To help applications be able to query what is supported, the various
PrintService implementation classes needed to be updated, for example "ID"
is reported as unsupported unless specifying using the native dialog on
windows.
That actually pointed out that back in JDK 7 when we added
DialogTypeSelection
to be able to choose native or Swing there was no query support for that
to be
added. It was not a problem though as if it was not supported it really
just meant
that applications would have to live with what dialog was provided, as
before.
But it made a test for this new API more difficult .. so I added code
needed for that.
The test is manual. An automated test might be possible, but probably
very flaky.
But the test only makes you run through the scenarios that we know are
supportable.
The motivation for this new public API is to help OpenJFX since it uses
the Java 2D PrinterJob class
to implement its own printing, so there is also an FX side to switch to
using this instead
of the earlier internal API which it can not access when it is outside
the JDK :
