Split Pane Problem

I have a panel with a split pane in it. On the Left hand side there is a Tree and on the right side is a complex tabbed pane.
(complex meand it includes many panels, more tabbed panes and other components).
My problem is this. I have given a specific width for the split pane for the tree and at start time it comes corrcetly. But when I move the Split pane left, suddenly it jumps to the left edge of the screen. And then I cant move it forward again. Tree cannot be seen now.
Why does this happen I just cant figure out.
Is it because of tabbed panes or something with the split pane.
Another thing is when I try to move the split pane to the left the movements are not smooth. It kind of do smaller jumps, until it do that big jump to the edge.
Any help would be greatly appreciated....

Design problem(split pane scrollpane Insets)

hi,
doing a exam simulator prgm
design is like,
Question (text area with scrollpane)
Answers (checkbox inside panel with scrollpane)
used split pane between qst and ans but big thick bar comes how to reduce size and it is not
moving.
used GridLayout for container and panel.
PROBLEM is how to leave space qst textarea appears from very left edge of screen how to leave some space
same prblm for checkbox they to appear extreme left on screen.

Put those components in a JPanel overwriting the getInsets() method like this:
JPanel cPane=new JPanel(){
    private final Insets _insets=new Insets(10,10,10,10);
    public Insets getInsets(){
        return _insets;
};...should do the trick, take a look at the Insets class if you need information on how defining it...

Split Panes, Frame and Resizing

Hi,
my user interface is made up of a message panel using the created class SplitPanes2 through the method createSplitPanes called from a class that extends Frame. (will post code if required: lengthy). When the frame is resized/maximized, the splitPanes remain at their preferred size. How can I work on it such that the SplitPanes will resize proportionally too? Please inform me if I have overlooked certain details.

Hi, I'm not sure, but I think I had a similar problem. I tried to place a JSplitPane inside a JPanel and then I got the same behaviour as you describe. Unfortunately I didn't find out why that happened. I simply didn't use the JPanel and then it worked as I wanted it to. (Almost) :)

Why was the split pane removed from Acrobat?

I recently upgraded from Acrobat 9 to Acrobat 11, and find that I'm not able to be as productive in 11. It's much harder to perform reviews because the Comment pane is difficult to work with. By default, the Comment pane is too narrow to be useful. If I undock it to try to put it underneath the document, I have to spend time fiddling with my windows to try to get the document the right size so that the undocked Comment pane can appear below it. The split pane was so much easier to work with; I hope that it will be added back in a future release. One other problem is that the scroll bar in the Comment pane is so narrow, it's difficult to click it.
Can anyone suggest any workarounds to help deal with these new features?

I tried the Touch Mode, which could probably help if I was viewing PDFs on a tablet, but unfortunately, it didn't do anything to increase the width of the Comment pane scroll bar, which is the UI element that I'm finding too narrow.
I would have thought that Adobe's main customers would be using review and comment features heavily, so it's disappointing to see these types of UI changes made.
As a workaround, I'm finding that I can at least split the page text, undock the Comment pane, and have it cover the bottom pane. That's a bit easier than trying to get it to fit under a resized main window. With most software that allows undocking, it usually lets you dock to a different spot, which would have worked fine here for those of us who would like to keep the comments at the bottom of the screen for better readability.

Adobe reader XI - Split Pane feature to be implemented?

Hello,
is it possible to implement the split pane function in adobe reader?
We already use the window-> new window feature but it would be great to have the split function so that we can manage only 1 pdf instead of 2, and it is quite more efficient to do cross references.
Thanks.

Hello Pat,
You are absolutely the BEST.
I followed your two recommendations and now the program is working perfectly. Yes, my Reader XI was version 11.0.10 when I was having the problems.
I never would have figured out the solution to the problem without your help. I was very pleased with your follow through.
I really appreciate your help. THANK YOU! – THANK YOU!
Adobe is a great program – I have used it for years and this is the first time I have had any problem.
Kind regards,
Hartley

Form pane X split pane

I have an application with a JSplitPane in the center of the GUI.... in this split pane I have a left JTree and a right JPanel.
on te JPanel on the right I have a form based on GridBagLyout, but it is very unstable... when I drag the split divider, sometimes te form becomes messy... with some fields over the other....
some tip ?

1 GridBagLayout is better than N-LayoutManagers ?Neither is better, which is why you have a choice. I prefer using whatever yields the easiest code to understand and maintain. For me this is usually a combination of the "basic" Layout Manager (ie. those Layout Managers without complex constraints)
is that really necessary to adopt more than 1 LM ?I don't know, but you did ask the question because you are having problems using just a single Layout Manager.
Either way there is no way we can offer specific advice because we have no idea what your form looks like.
I suggest you read this before posting any further:

Numbers is not an Excel clone. Importing and exporting between Numbers and Excel will eventually build up glitches.
If the university only works with 'Windoze' it might be better if you use Excel or a free version of Office (for example, Libre Office or Open Office).
If your marks depend upon a professor who uses Excel, go with the flow.

Drag and drop icons from onside of the split pane to the other side.

Hello All,
I am tring to write a program where i can drag and drop icons from the left side of the split pane to the right side. I have to draw a network on the right side of the split pane from the icons provided on the left side. Putting the icons on the labels donot work as i would like to drag multiple icons from the left side and drop them on the right side. CAn anyone please help me with this.
Thanks in advance
smitha

The other option besides the drag_n_drop support
http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.htmlis to make up something on your own. You could use a glasspane (see JRootPane api for overview) as mentioned in the tutorial.
Here's another variation using an OverlayLayout. One advantage of this approach is that you can localize the overlay component and avoid some work.

Sun Fire V490 x 2 servers with Oracle RAC facing Split brain problem

Hi all,
I have Sun Fire V490 x 2 servers with Oracle RAC and they faced a Split brain problem. One of the node's database instance has gone down, The DBA claims it is due to network problem, but as such the networks are OK. We use the on board CE1 interface for Cluster interconnect and CE0 as the public interface.
Did anybody face this kind of a problem? Could this be a hardware/OS patch problem?
I had kept a continuous ping for 24 hours after this happened last time and the output shows no packet loss
Many thanks in advance.
Ushas Symon

In order to diagnose this properly, you'll need to provide too much detail and far too many log files for a generic discussion forum to handle.
Use your service contract and open a support case.
Because a cluster environment is involved you'll likely end up talking to the cluster support staff.
They can analyze hardware and software errors as well as review whether you configured the systems in a supportable fashion.
Be prepared to make a direct connection to each system and gather data using such as by using the Explorer tool. The technical support staff will tell you what they will actually need.

Split Brain Problem

Dear All,
RAC Database Version is 10.2.0.3, and Operating System is SPARC5.10.
The Database use Veritas Sun Cluster.
Voting Disk Size = 10MB
Yesterday, it experienced Split Brain Problem. Each Node Assumes it is the only surviving member of the cluster.
At first, Node 1 became hung and the network link was broken, then our system admin decided to restart the server.
After that, Node 2 Work Load increased significantly, and there was nothing we can do in database.
Fortunately, Veritas Team could handle it, by cleaning the process that was hung.
In my opinion, interconnect communication between node1 and node2 was broken, then each node assumes that it is the only member of the cluster.
To prevent Database Corruption, Veritas Cluster blocked every changes to database.
So, Would you tell me what is actually happened,
was It Related to Heartbeat to Controlfile, considering there was ORA-600 [2103] ?
Best Regards,
abip

Take a look at Bug 5526987
This issue is fixed in
10.2.0.4 (Server Patch Set)
11.1.0.6 (Base Release)
Symptoms:
Related To:
Internal Error May Occur (ORA-600)
Hang (Involving Shared Resource)
ORA-600 [2103]
Automatic Storage Management (ASM)
Description
This problem is introduced in 10.2.0.2 by the fix for bug 4671216.
A file creation rollback in ASM can lead to an ASM
instance hang when the rolling back session tries to get
the FA enqueue in X mode but it is already held. This can
lead to an ORA-600 [2103] on the database instance.
This issue is marked as a notable fix and it is recommended
to install a patch for this issue where ASM is used.
Further details on this issue can be found in Note 468572.1

Can you hide the divider of a split pane ?

I have a split pane, the application also has menu options that allow the user to turn off one of the panes if they like, this results in the pane disappearing but the splitpane divider still exists.
Can this be removed, and if not is it acceptable look for the divider to exist when only one side of the splitpane is visible, or do I have to remove the splitpane from its parent and just add the visible component of the splitpane to the parent directly when only one is selected, reversing the code when user wishes to have both visible.

Thanks that works fine. Although it is a shame there is no splitpane.getDivider() method, I assume there is no explicit guarantee that the LAF being used actually subclasses BasicSplitPaneUI, so I need to make appropriate checks.

Textpane does not fill up right comp of split pane

I am a novice when it comes to swing. So please pardon me if the question I am sking is a bit silly.
I have a split pane , with a resizable divider. the rightcomponent houses an internal frame used by for a JEditor Pane.
How do I set the size for any new JEdiorpane , so it takes or fill up the right hand side of the split pane. Bearing in mind that the divider might have been moved so the right component area is not at the preffered size.
Should I be using a listener to take note of the current size of the split pane component?
Any advise wil be appreciated.

Sounds like it might be a sync issue. Have you tried powering the monitor off and then back on with the MBP connected to it? How about just temporarily disconnecting the DVI cable from the desktop PC and using that to plug into the MBP.

I can't type in the design portion of split pane view.

When I try to type in the design portion of split pane, the design pane becomes white and won't except any input. Basically it is forcing me to do everything in the code portion of the pane.

It is dreamweaver CC for Mac OS X. Yes, I have done that. Here's a picture to illustrate what is happening:
BEFORE:
I place my cursor after the last bullet point, "Status" in the design pane. When I hit Enter on my keyboard to create another bullet point (at least this is how it worked in previous dreamweaver versions) this is what I see:
