[Openrpg2 dev] Custom Layout Manager

[NeoSkye <djj...@ya...>]

I haven't figured out yet how to manage the JPanels in
an SDI environment. That's mostly the reason I haven't
worked on it yet. My dream layout I think would be
something of a dockable interface where the user could
drag a JPanel to the general location of where they
want it. If you know how the SDI would be best
accomplished though, feel free to write it.

I'm a bit confused about the suggestion for a pack()
call. When do components get cut off? what components?
sorry, just really confused there. But I will
definately work on the hide/show feature.

I take it then that you have never designed a LayoutManager before?

They are actually very easy to design, and even kind of fun... once you 
get the hang of it.

Netbeans includes the source code to one... AbsoluteLayoutManager... I 
recommend loojubg at it for getting the basic idea of how to create your 
own.

(Just don't use the same serialize id).

You can also find a few other sample layout here:

Creating dockable components is an entire project in and of itself. 
Doable, but quite complex.

OSX shows this effect more dramatically than XP but here
is an image with the 'cut off' areas pointed out with red
arrows. http://rpg.game-edit.org/orpg/screenshot1.jpg

On OSX the frame cuts off the popup window roughly though
the middle of the text line. I can get you a screenshot of
that tomorrow if you'd like.

In case you don't know pack() resizes containers so they
fit the minimum size of its components.

See the difference for yourself...
Add "newframe.pack();" at line 53 in MDIFrame
(as of SVN revision 53) as shown below....

public void addModule(String modulename, JPanel modulepanel) {
     JInternalFrame newframe=new JInternalFrame(
         modulename, true, false, true, true);
     newframe.setSize(modulepanel.getPreferredSize().width+10,
         modulepanel.getPreferredSize().height+20);
     newframe.getContentPane().add(modulepanel);
 >   newframe.pack();
     mainPane.add(newframe);
     newframe.setVisible(true);
}


This is one of those things I'd usually commit without delegation
but, being as you asked I figured I'd oblige.

This is sort of weird... it's like it's trying to use the minimum size 
for the panel, but it probably should use the preferred size instead.

Now this much I am certain of, pack() always tries to use the preferred 
size of components, not the minimums size.
