Netbeans, java3d, menubar, toolbar, jpanel HELP
I'm attempting to make an application using netbeans which features a menu, a toolbar, and a jpanel beneath that which displays a Canvas3D. I got this to partially work, but the Canvas3D will not automatically resize. If I .add the canvas3D to the frame, then it resizes automatically but it writes over the toolbar (but not the jmenu since I made it inherit jpopupmenu).
Does anyone know of some good information for how to get 3D to work with a Java application? I don't even care if its Java3D...JOGL...any of the 3D libraries out there would be fine, I just need it to cooperate nicely with a GUI toolkit!
thanks for any info!!

Hello, I am fighting with the netbeans platform + java3d as well and I am seeing the same problems as you have reported.
Are you using the netbeans RCP framework ?, if this is the case, could you
send me an email: [email protected]
Thanks a lot in advance!

Can't Attach Files in 10.9 Mail via Menubar/Toolbar
All of a sudden I cannot attach files in Mail via menu commands. A selection (finder) window opens but all items are grayed out (no matter what location). I can still attach files by dragging them from the Desktop (or other location) into the body of the email.
Isolation:
-Issue persists in Safari when logging into webmail.
--Choosing to "attach" a file to an email (new composure or reply) from the webmail attach links brings up a Finder window with all content grayed out.
-Created test admin user.
--logged in as new user.
--set up Mail w/ an email account.
--attempted file attachment from menubar/toolbar icons.
--works.
***issue is user specific.
Resolution:
-Access primary user ~/Library/Preferences/.
--locate files named "com.apple.finder" .plist (may have multiple files w/ additional characters).
--select all and move to Trash.
--Restart.

Recently installed OX X 10.5 Leopard and ever since, I can't attach files to outgoing Gmail emails.
I've tried in Safari, Camino and Firefox -- no luck.
It does work if I switch to the "older version" of Gmail.
Does anybody know if there's a setting I can change so I can use Gmail normally but be able to add attachments to mail?
Anybody else having this issue?
Your profile indicates you are running a very old version of Leopard which might explain the issue.
Update to 10.5.8 using the combo update (not the auto software update) and see if that fixes your problem. -

using this coding i just removed the ie menubar ,toolbar as well as address bar.
but i want to disable all.pls address this..
Regards
Gopinath Mya Wesley ,i tried but my customer want to one window at a time.
using that java script i can show one window but the IE is not positioned.
how can i set the x , y position of IE else if i disable the toolbar,menubar
that window automatically positioned.at the meanwhile the user should not close the windows closed like ''x'' .it will ask the message like do u want to exit?.
these are my requirement kindly address the same .

I can't save bookmarks to my toolbar. Help Please
I have a new Macbook Pro and when I migrated everything over, nothing moved with Firefox.
I am now trying to add bookmarks to my toolbar and they are not being saved in the toolbar. I have closed and reopened Firefox, have the latest version and nothing is happening.
When I Show all my bookmarks it shows them in a folder. When I try to re add them to the Toolbar, they will not stay.
Please help and please dumb it down.It is possible that you do not have the "Bookmarks Toolbar items" on the Bookmarks Toolbar.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible.
*Firefox menu button > Options/Preferences
*View > Toolbars (press F10 to display the hidden Menu bar)
*Right-click empty toolbar area
Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.
*check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar
*if "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette into the Customize window to the Bookmarks Toolbar
*if missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
*if you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar setup
*https://support.mozilla.org/kb/How+to+customize+the+toolbar
*https://support.mozilla.org/kb/Back+and+forward+or+other+toolbar+items+are+missing -
Win 7
Firefox 5
Problem with high memory use.
restarted
Plugin buttons gone from toolbar/
Missing plugins still show in plugin manager but buttons missing from toolbar add buttons pane.
Tried reset toolbars - no difference.
Tried re-instal of Firefox 5 - no difference except:
Session manager offers correct session on startup but starts with last sessionIn case you are using "Clear history when Firefox closes":
*do not clear the Browsing History
*Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings
*https://support.mozilla.org/kb/remove-browsing-search-and-download-history
Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
*http://kb.mozillazine.org/Multiple_profile_files_created
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible). -

where's a good place to learn "whats under the hood", most tutorials just say, "type into your command line: bla bla bla" without explaining why or what this includes when doing so or anything remotly interesting apart from what to type (not helpful when wanting to learn whats under the hood)

Hi guys, I currently have an odd problem. I am finally using Netbeans on my Mac. I currently use it on my Windows machine as well. On my Windows machine if gives you this option up by the toolbar to either have Design or Source showing. I mainly want to do this to do GUI design obviously. On my Mac however, it is not giving me these option up near the top and I looked all over to try and figure out. I have the project opened up as a Netbeans project and everything like it should be and still no luck. Any idea on how to see the current Design?
Thanks,
DerekPossibly, I dom't know how Apple implemented the Matisse details - it does support Matisse, right?. If the class will open as a GUI in NB's editor on Windows, bu not on the Mac, then I'd say that's the cause. Is that an error? Possibly, possibly not.

Importing Widget - Menubar 2.0 - Help!
I went to widget browser, and to adobe exchange where I formatted Spry Horizontal MenuBar 2.0 exactly how I wanted it...saved it to my presets. (It showed up on the adobe exchange horizontally like I wanted it. Then I opened a page in dreamweaver CS5, chose insert > widget> my presets> and chose the formatted Horizontal MenuBar. All the code for the widget was imported onto that page. I have two problems.
1. It shows up vertically. How do I get it to show up horizontally?
2. And was there a better way to import it so I do not have to have ALL the code on every page in my website. I am worried that it will hamper spiders.
I thought it would go into the spry assets folder.
I have not cleaned up all the comments in the code yet. It is located here
http://www.bountifulspinweave.com/alpine_meadow_yarn_starlight1.htm
Thank you in advance for any insight you can provide.
Sincerely, LoisThank you for your help and for the additional websites to visit for help.Thanks to your input, I was able to build a new page and get the menubar to work and validate everything except for three min width errors in IE 6. I had 0px for the min width by default. I tried 0%, 0em and 2em but that did not help. So I will just put up with that error I guess.
I am still unsure if all the code for the spry menubar 2.0 should be in the source code for every page and not in a separate file uploaded to the spry assets folder. I simply went to widget browser, to my presets, then inserted it on my page. Will all that code affect spiders cataloging my site?
Thank you again!
Sincerely, Lois -

i am creating a split pane in which on the left i am adding the device panel which is giving the problem even though the panel is bigger that the scrollpane's size it is not showing the vertical scrollbar. the right side with the text area is working fine -
JScrollPane containing JPanel HELP!
Hi again,
I'll try my luck again!
Ok, I have a JPanel that uses a GridBagLayout with 3 columns and many rows. Each row is of the form:
[JLabel][JTextField][JButton]
Ok. Since I have many of these rows, and my application should be a constant size, I need to somehow make you able to scroll down the list of these labels,textfields and buttons - to the one you want. I have tried making the containing JPanel the viewport of a JScrollPane, however, when I only have a couple of rows of labels, textfields, and buttons, each expands to fit the viewport size - and they turn out looking really dumb.
How can I get it so that the labels, textfields and buttons are only the height of the text in each?
Please please, please, please help me.
sincerely, Edd.Chenge the weight (x&y) in the GridBagConstraints of the components you don't want to expand to 0.0. Change the fill to GridBagConstraints.NONE.

JPanel help, i am so very noob
hey, can someone help me with Jpanel, i want to make the JPanel like a gridlayout, does anyone know how? if not, can a Jframe have like a selfcontainedframe? (just wondering, i don't ecen know if that word exists, i know jpanel has a selfcontainedpanel or something)
Maybe you want in Internal Frame:

NetBeans Problem with package, pls help.....
Hi all, I have a package problem. With the following 2 classes, I can compile fine in dos with
c:\java> javac WapDev3\*.java
but wont compile in Netbeans 3.4 Pls help.
The classes are
-------------------class sample1 at c:\java\WapDev3------------------
package WapDev3;
class sample1 {
public sample1() {
System.out.println("hi");
--------------------class sample2 at c:\WapDev3------------------
package WapDev3;
class sample2 {
public sample2() {
public static void main(String[] args) {
sample1 osample1 = new sample1();I don't know for certain whether this is causing your problem, but in Netbeans, the package structure is considered to be identical to the directory structure, relative to the mountingpoint, so if your files are in java/wapdev, Netbeans wants you to make the package java/wapdev.
This can be cured by mounting a subdirectory, using a relative mounting point.
In your case, you should mount C:\java (I assume you've mounted C:\).
Good luck. -
