[jira] Created: (PIVOT-418) Multiple host windows

Multiple host windows
---------------------

                 Key: PIVOT-418
                 URL: https://issues.apache.org/jira/browse/PIVOT-418
             Project: Pivot
          Issue Type: New Feature
            Reporter: Mathias Versichele
            Priority: Minor


Until now, all Pivot windows run within a single native host window (which can hold child windows). Some applications could, however, benefit greatly from the possibility of having multiple host windows ('parent windows'). For example, one could then use the possibility to use different monitors for each host window in a multi-monitor setup (e.g. one window 1 one monitor 1 for basic tasks, and window 2 on monitor 2 for heavy-duty 3d rendering).

Agreed. I think the only way to keep this logically portable is to allow one
window to own another window and when a window is owned by another, that's
when it's a toplevel frame (or maybe I have this backwards).

Not yet, but there is a ticket for that as well:

  https://issues.apache.org/jira/browse/PIVOT-368

However, when possible, it is best to try to avoid introducing a hard
dependency on a particular application context, because that make an app
less portable.

Okay. I understand your comments. I'll try this out and see how it looks.
And of course, knowing nothing about the rendering layer, perhaps there is a
way that the rendering layer or application context understands when it is a
desktop or not and can do different things. But I'll try the standard
approach before anything else.

That is also how Pivot windows behave. However, all Pivot windows live
within the Pivot "display", which is itself entirely contained within a
single native frame or applet (specifically, it lives in a "display host"
which is a child of the native window). That's why Pivot windows appear to
be constrained to the client area of the native window. This is by design -
it gives Pivot complete control over the appearance of all UI elements
including the window and its associated trim, and allows us to create a user
experience that otherwise would not be possible (for example, "sheet"
windows are supported on OS X but not on other platforms). Windows in other
RIA frameworks behave similarly.

However, there may be times when opening multiple native frame windows in a
Pivot application is desirable. Currently, this is possible but not easy.
The solution proposed in this ticket would simplify the process by allowing
an application to create multiple displays, each of which would be contained
in its own display host and native frame.

That said, this is actually considered to be something of an edge case.
Generally, when a Pivot application requires a dialog or an alert, the
recommended practice is to use a sheet or a prompt instead. Sheets are
attached to the top of the owner window and can't be moved by the user. As a
result, they can't be dragged "off screen" like a frame can. Perhaps this
approach would work for your application?

Appddevvv commented on PIVOT-418:
---------------------------------

Would this address the issues that dialogs seem to only exist within the bounds of the parent window versus a separate free floating window (at least on the desktop)?

I have no control over which classloader loads my pivot app in this 
particular case because I'm running the application inside Eclipse's junit 
testrunner.  I spent a while trying to get it to work, but unfortunately I 
just have to run each test individually instead of as a suite.

It may. You just need to be careful about your use of static variables. Or, you might consider using a custom class loader for your applications. I haven't actually tried it myself, but it is something we have talked about in the past for running multiple applications.
