Setting a minimum (enforced) size for the Display
Hi,
I've currently using Pivot for my project, after I decided to abandon Swing.
I prematurely apologize if this is a dumb question, since I've only recently
started using Pivot.
Basically, I was wondering if I could enforce a minimum size (width and
height) for the display of my Pivot Desktop Application; that is:
In the event that the user resizes the Display to something smaller than the
minimum size and height of the child Window, that the Display will remain at
the minimum size of the enclosed child window.
If the user has a large monitor, and sizes the Display to anything larger,
all the child elements and display will scale to the larger size.
Currently, I've tried to add a ComponentListener to the Display passed in
startup(). The componentListener has the sizeChanged() function implemented
to call DesktopApplicationContext.sizeToFit() on the child Window. However,
doing this causes the window to "seize" and flicker everytime the Display is
resized by the user to a size smaller than the minimum size; thus this
solution is not ideal.
Any tips and advice would be appreciated; however, I personally prefer to do
this completely programmatically in Java, and would not like to use WTKX
(for now), unless using a WTKX source with my application is the only
solution.
Thanks,
Dave

Thanks for your help! It seems that from the source code listed below:

That I need to call getParent() off of the display host; Ill try this and
cross my fingers.

Could you just post your source; you mentioned that you were able to get it
to work? Since I was not able to find getHostWindow() in java.awt.*. I tried
the following and got an error when running my pivot application in eclipse:

1.5.2 is the latest stable release, though I would recommend looking at 2.0 if you can. It is very close to release and offers a lot of improvements over 1.5.x.

You can pass "--resizable=false" to DesktopApplicationContext. You can also pass --width and --height arguments to set the size. However, getting the root Window and setting a min size on it should work. Let me know if you run into any problems.

Ok, thanks for the help!
On another note, is 1.5.2 the latest stable version? If 2.0 is stable, where
could I grab it (as well as the javadoc?) Since on the apache pivot site
1.5.2 is the shown version; if 2.0 is still beta, then nevermind.
Also, in the very strange event that I am unable to get your suggestions to
work, what would I need to do to make the entire application not resizeable,
that is Window/"Host Frame"? and/or Display?
Thanks,
Dave

Sorry, we must have added that method for 2.0. You can still get access to it in 1.5, though. Call getDisplayHost() on the display and then walk up the AWT hierarchy until you find the root AWT Window.

This is probably a very dumb/trivial question, but, I cannot seem to find
getHostWindow() in the 1.5.2 javadoc. I googled for getHostWindow(), and
found some stuff on it in the commits mailing list, suggesting that it is a
function of Display; but when I check org.apache.pivot.wtk.Display in the
1.5.2 javadoc, I don't see the function.. do you mean calling <name of
display object>.getWindow().setMinimumSize(..) instead?
Thanks for all your help so far.

You are setting the min. size on the display host in this example - you need to set it on the host window (returned by getHostWindow(), not getDisplayHost()). I just tried this and it seems to work fine.

Re: Setting a minimum (enforced) size for the Display

One solution would be to have the native host respect the max/min size of the display. We might be able to do this simply by having DisplayHost override getMaximumSize() and getMinimumSize(). Feel free to enter a JIRA ticket for this if you think it would be useful.

With regard to the original undesirable solution of the window resizing, and
then flickering back to its resized-but-less-than-minimum size...
If there is a way to check that both the componentListener's sizeChanged()
method was fired, as well as a mouseUp event, the sizeToFit() method could
be called during the mouseUp event; if this was possible, the window would
still do its flicker action, but at least the window would remain the
minimum size of 800x600.

I've tried your solution and it does not seem to have any effect; Is it
supposed to set the size of the Display (and enclosed Window) to 800x600 on
startup()?
I have posted the code below for reference. constructContent() simply
returns a BoxPane filled with other stuff.
Thanks,
Dave
private Window window;
public void startup(Display arg0, Map<String, String> arg1) throws Exception
{
window = new Window();
window.setTitle(Constants.APPTITLE);
window.setContent(constructContent());
window.setMaximized(true);
arg0.getDisplayHost().setMinimumSize(new Dimension(800,600));
window.open(arg0);
}

Re: Setting a minimum (enforced) size for the Display

This isn't currently supported. However, you could simply set a minimum size on the host window. For example, call setMinimumSize() on the value returned by Display#getHostWindow().
