 |
|
I cant find anywhere info on how to use the jbuilder ide to create an
app that uses internal frames (JInternalFrame).
I created an app with a JFrame, then created an internal frame, but
then what?
could someone point me in the right direction please?
Thanks

Look in the following directory for the SwingSet2 sample code:-
cd JBuilder<version>jdk<version>demojfcSwingSet2

Thanks, but I'm wondering how to do this with Jbuilder generated code.
The JInternalFrame in that example cant be modified in the Jbuilder
IDE visual design.

As far as I am aware no support in JBuilder to develop or manipulate
JInternalFrame in the Visual Designer.

you can create a JInternalFrame by File-New-Frame , then select
JInternaFrame as the base class. you can then edit the JInternalFrame
in the visual designer.
But how do you incorporate it into your project? I want to make an MDI
type application.
I have been working on this a long time, if anyone has done this
please let me know how.

Look at the sample below. I have not included the Data Module (since it is
proprietary for the application), but the other code will work (i comment
out the specific calls to the DataModule).
Note this is a long post. If you create a new Project in JBuilder and use
this code, it should work. You will need to add a new DataModule, called DM
and palce it in a package as indicated below before compiling.
ShowResultsTable will not work unless you reset the QueryDataSet used for
the JdbTable.
Note: To visually create a JDesktopPane, ou can add a JPanel to your
MainFrame, and rename it in code as per the notes in the code below.

That should do it for you..

yes - thanks very much for the detailed example- Ive got the internal
frame working now.
Odd that the JDesktopPane isnt on the component palette.
It looks like there is a lot more to an MDI app than I thought...

yes & thanks again for that. but for example I dont see how menus for
each internal frame would be managed.
I have only done windows desktop apps up to now but would like to be
able to use Java if possible.

You do not create Menus for each Internal Frame, no more than you would for |
a MDI Windows application. Your main frame should contain your Main Menu
which would be used throughout the Application.
Calling a Internal Frame from your Menu works precisely as per the code
snippet in the example.
void jMenuItem2_actionPerformed(ActionEvent e) {
ShowResultsTable srt= new ShowResultsTable();
this.jdtpMain.add(srt,BorderLayout.CENTER);
srt.setVisible(true);
}
If you had other Menus for other calls to Internal frames (and no doubt you
would), you would simply call the next internal Frame
void jMenu3_actionPerformed(ActionEvent e) {
ShowOtherInternalFrame soif= new ShowOtherInternalFrame();
this.dtpMain.add(soif,BorderLayout.CENTER);
soif.setVisbile(true);
}
Of course what I normally do is create a single instance of a JInternalFrame
and create separate panels that I will call from my JInternalFrame class.
That why, I can do a counter on the number of instances on ,y
JInternalframe class and control which Window is active. A little more work
invovled of course, when you do this, but once done, you have reusable
classes.

Well actually in a windows mdi application the child windows do have
their own menus that appear in the main menu as each window gets
focus. that is what Im wondering how to accomplish.
Also a window menu to switch between windows etc.
If java apps have a different paradigm I am open to learning it.

Just a note here. I've been doing a lot of work on "Usability" in
applications over the past year. The paradigm of having menus change
when different internal frames are given focus is considered a *very
bad* in terms of usability. Just because a particular idiom is in
common use, does not mean it's a good idea.
Consistency is good. There's lots of information on usability out
there. One good place to start is http://www.foruse.com

Hi Lori,
A comment --
Different frame -- different menu is kindof the Mac app/finder
UI paradigm. Some people like it -- some people don't
It can be made to work (that is, be usable) if the user's sense
of context is maintained. How that is done is up to the needs
of the user population and the requirements of the application and
the capability of the hardware and of course the skills of the
UI designer.
Lastly, users adapt to various UI's. The flexibility and adaptability
of the cognitive process is not to be under estimated. The variety
of valid UI designs are about the same as the variety of opinions
about it...

I found this article quite useful:
Create a scrollable virtual desktop in Swing
http://www.javaworld.com/javaworld/jw-11-2001/jw-1130-jscroll.html?
also discovered a JInternalFrame can have a menu although doesnt seem
to work in designer.
