Help setting node height in a JTree
I have a JTree in which i would like to make the font of the nodes somewhat large (size 16). However, by setting the node's font to this size, i notice that the top and bottom of the node values are truncated. I was wondering how i could increase each node's height so that the value can be easily readable. I have tried extending DefaultTreeCellRenderer and setting the preferred and minimun sizes. I have also tried using a panel as my TreeCellRenderer and setting its sizes. Neither of these attempts worked. So, does anyone out there know how to set the node height or node spacing of a JTree?
When I set the font on the JTable, everything seems to scale well.

Hi There,
I have set the laf of my application to be Windows Look And Feel.
In case of windows laf, the Row Height of the JTree is not changing from the default one. I want All my Leaf to be of Different height than the Nodes.
I have rendred my cells to JLabel. Even if i am setting the preferredSize of leaf and node to different values, stil it is not working!!!!!:-(
In case of Metal (Swing Default laf) it is not a problem.
Is there any solutions?Well I could but I have a very busy time now. I can tell you that your Renderer is ok and all you need to do is to notify your model on node change at the moment you need to change node's height (this moment could be node selection / unselection). Everything else is automated for you.
You can use my library to have an easy way your model to be notified.

How to set the height of a textarea dynamically
Hi,
I have been trying to set the ui.textarea's height dynamically and I am not able to do it. This is what I am doing.
<ui:textArea binding="#{assignment$EditResult.textArea2}" id="textArea2" style="height: 90%" text="#{currentRow.value['comments']}"/>
The height is being ignored and it is set to the default size. How can I set the height of this component to fit to the size of its cell, which is dynamic?
Thanks for your help.Thank you for your help! It worked for something like this:
getTextArea2().setStyle("color : red");
but this does not work still.
getTextArea2().setStyle("height: 90%");
I think it still does not know the size of the cell at this point yet. But this is a good tip, thanks anyway!

Set isolatedHtmlContainer height when displaying portal page
Hi,
I have a portal application which displays portal pages from the pcd in isolatedHtmlContainer.
The page's content is dynamic so the height is not fixed and therefore in the page's properties the height's value set to 'Automatic'
However, when working with isolatedHtmlContainer the height could be set in pixels or percentage only (I cannot set it to 'Automatic').
p.s
If the height was fixed I could get it by the profile of IPortalComponentContext, but if I will do that I'll get a string like 'Automatic' which doesn't help me...)
Thanks,
OmriHi Martin,
I read the blog but the javascript doesn't affect my IsolatedHtmlContainer.
Let me rephrase my question:
In the portal innerpage I display X IsolatedHtmlContainers (my application decides how many pages to display). Each container has dynamic content (a portal page from the pcd), therefore, I have a problem setting the height of the IsolatedHtmlContainers (too low - scrolling bar, too high - blank space).
The properties of the portal pages from the pcd are set as follows:
isolation method - URL
height method: Automatic
If I display the pages without the IsolatedHtmlContainers, the 'Automatic' feature works and the page's size is OK.
So my question is:
Is there a way for the IsolatedHtmlContainer adjust its size according to its content?
Thanks,

Help understanding Node.boundsInLocal, Node.boundsInParent?
Hello all,
I am reading the JavaFX2 API to understand the getBoundsInLocal() and getBoundsInParent() methods for a Node. I understand the Bounds object that is returned. I would like to better understand the difference between the two methods.
I read in the API that the getBoundsInLocal() method returns "the rectangular bounds of this Node in the node's untransformed local coordinate space." Am I correct in thinking this is prior to any transformations? So this would be the height, width, x, and y coordinates at initialization?
The getBoundsInParent() method says "The rectangular bounds of this Node which include its transforms." Does this include transformations?
My next question is to understand the getBoundsInLocal() method as it is used in this demonstration. Below is an example of creating custom button written by Eric Bruno (http://www.drdobbs.com/blogs/jvm/229400781).
In the ArrowButtonSkin.java class, Eric is setting the label width and height. When I run the program I see the width value is -1.0 and the height is 0.0. So the control renders as a dot on the screen. Is there a reason the methods below are returning -1 and 0? I am not sure where I went wrong. It works if I explicitly set the values.
double labelWidth = label.getBoundsInLocal().getWidth();
double labelHeight = label.getHeight();
Thank you for assistance.

Help setting up BTinternet email with Apple Mail
Hello everyone,
I need help setting up a btinternet email account with Apple's Mail sofware. I am setting it up on behalf of my aunt and uncles new macbook pro so I hope i get some solutions quick because Im leaving their place by the end of the weekend and I would love to have their email setup and teach them how to use it.
They have 2 btinternet email accounts, the first one they use alot as its their main email account which is currently setup on MS Outlook on their old computer. The secound one they use rarely and its not setup on MS Outlook.
Heres the problem, when I setup their main email account with apple mail, I have no problem creating the account however once created the inbox is empty - it does not load previous emails. It can send emails fine, if i send an email to the account using my personal email it will receive it but when I switch off the computer and switch it back on the mail box is empty. So I checked the email account by going to yahoo.co.uk and signing in - again even on the web page the mail box is empty.
I then setup the second btinternet email account on Apple Mail shockingly this works perfectly all the old emails got loaded up in mail. So how do I do this for the main account, I know the difference is Outlook mail but I rather not delete that because if it doesnt work then they would lose all their old emails.
Please help
Thanks in advance
PS: ive setup my hotmail and yahoo accounts and they all work fine by the wayPlease guys give me something or any random ideas u may have. im running out of time.

Need help setting up 3 different iCloud accounts for my kids (so each has own iMessanger)using same Apple ID (mine) ....they don't have their own separate email addresses to work from...how do I do this?
Any devices connected to the same icloud account can sync all the data on that account. For this reason an icloud account is really for a single user.
On a mac, if each user has their own account, then the itunes for that mac account should be set up to connect to that user's icloud account (System preferences>icloud). -
Help setting up my new IPod Touch on iTunes on windows 7 64bit
Hello there,
I need help setting up my new IPod Touch to my Itunes 10 application on a PC running windows 7 64bit. I have watched the tutorial on how to do it but what the tutorial says it is supposed to do is not what is happenning for me:
1. In the tutorial it tells you to connect your ipod to your computer, then, (if it is for the first time) when the ipod appears and is selected, a window will come up allowing you to name your ipod, and begin selecting the options you wish to use.
I did as instructed but quickly came against some technical issues.
My issues:
1-1: When I selected the new iPod Touch for the dirst time I got an error message.
A) This was quickly fixed once I calld up apple support on the phone (turns out an IE browser setting was blocking it.)
1-2: With that fixed I selected my iPod Touch again but instead of the window indicated by the tutorial, I instead got an iPod registration form window.
1-3: I filled out the form and pressed the submit button (thinking everything was fine), then a new window came up that looks like this:

The first three lines and the first paragraph are indented as if there should be some type of graphic there, but it is missing. The underlined words indicate that they are supposed to be links, but they don't go anywhere, they are broken!
Now wheenever I connect my iPod Touch and select it the above window comes up and nomatter what I try it will not move or change.

I had to call Verizon and spend an hour on the phone, my Versalink is about 3 years old and I never updated it. There is a software update which makes it a little more mac friendly. Cables still run through it on the Ethernet port. I was able to turn the wireless feature off on the Versalink (to stop my neighbors and kids from bypassing the APE and just factory reset the APE and set it up with a shared IP adrs instead of bridging it. Also made sure I turned off the guest network on the APE. Once it was set up I clicked on Airport in the Airport Utility then wireless Clinets, jotted down the client I wanted to restrict access to (Kid's Laptop) then go back to Airport screen, last option on right Access then MAC Adrs Access Control change to "Timed Access", then click the + on the bottom of the window, type the MAC adrs you want to restrict and set time limits, when complete click done..... Only took me a week and a half to figure it out...... Good luck, if that doesn't help let me know, but I'm no expert...
thanks!!
i think i have the most recent 327w update, because it now shows my modem screen in a red color and it is broken into 3 sections across the screen.
as far as the AEBS is concerned, you did not use it in bridge mode at all?
i thought you had to connect 1 cable from it to the 327w? I have about 5 items i will be connecting, so i will probably run any wired from the AESB, but not sure yet?
thanks, and yaeh last time my network took me a bit of time as well!!
what kind of encryption are you running?

Teresa,
I think the best way for someone to volunteer to help you would be for them to send you a Private Message (PM) here on the forums. You should see a small envelope in the upper right corner of the screen, when it changes color you will know you have a PM to view.
I would be happy to help, but since I am in North Texas I don't think that is a viable option Sorry....

Need help setting up and configuring rsync
Hello
I need help setting up, or rather configuring rsync to sync data between my brand new iMac and my Macbook Air.
Here is what I would like to:
- I want all of the files on both machines to be an exact mirror or copy of each other. Basically I have an iMac for at home, and then a Macbook Air for the road.
- The main folder on both Macs is called 'Sara' and I want the contents (mainly the 'movies' folder, 'music' folder, 'documents' folder and 'pictures' folder) to immediately sync up with each other when both of them are on my home network.
- this means if I'm working on a file at home on my Macbook, it will immediately write to the same directory on my iMac and vice versa (if I'm working on file(s) on my iMac, it will immediately save the contents to my Macbook). This way, if I'm working on last minute project my iMac, and then have to head out the door to the airport, the file is immediately saved to my Macbook (no usb for USB transfer).
- hopefully this makes sense??
Any help is greatly appreciated!
ThanksIt's a lofty but unrealistic goal. Rsync does not run automatically. There is no realistic method of instantaneously synching two computers over the internet or even on a LAN.
I would suggest you might try using Synk Pro which, in theory, can keep two devices in sync when they are both on the same network (and both have shared and mounted drives.)
If you must do this with rsync then I suggest a Google search for rsync tutorials. -
Using JDAPI to set the height of the Forms Canvas to it's default value
Hi,
I've been trying for a while to use the JDAPI to set the height of the Oracle Form Canvas to it's default value.
Can anyone advice how to do this ?
Can the currCanvas.inheritProperty(arg0) be used in this case ?
Thanks in advance,
regardsHi David,
Note that I used a Footer Row in my Table. Headers and Footers have special properties. (A poster in the last couple of weeks asked for a summary of Header and Footer properties - somewhat frustrated that he couldn't find a succinct description in the User Guide. Well, there isn't one and the answer is so complicated that nobody has taken on the project. Now we have a new version of Numbers and the answer would need to change.)
The way to avoid the error is to use a Footer Row and to use the shortcut cell reference notation: =SUMIF(C,TRUE,B). The columns are specified, but the row range is not. Footers are exempt in this notation, so no error is generated regarding a circular reference.
Hope this clears it up.
