Using swing and swt together

i would like to use some of the components of swt such labels or buttons in swing as swt has better look and feel. but in all the examples i found they are using a whole set of swt api to create frames and showing them up.
Isnt there any way to add button or label of SWT in Swing. i found a method SWT_AWT.newFrame(). But it is returning a awt frame not a Swing JFrame that at the frame level. i need them at individual component level(buttons and labels).
hope u understood my problem.. any other suggestions??

Swing and SWT are two different framework. Usually, peoiple choose one and stick with it. I would not mess with mixing SWT with Swing or vice-versa. I really don't understand why you would choose to mix these two framework together. "better look and feel" is not the best answer for this. what i would look into is a look and feel for Java (like JGoodies look n feel)..and check for Swing component that pther people have made (or enhance upon the Swing library).
Stick with one framework. Your life will be much easier.
Futhermore, maintainance would be less difficult. (you only have to know one framework instead of two, plus how they interact)

Difference between AWT,Swing and swt

Hello,
I am giving a seminar about swing in which I need to point out differences between AWT,Swing and SWT(Software Widget Tool).
I have two questions:
1)I read that-A heavyweight component is one that is associated with its own native screen resource (commonly known as a peer). A lightweight component is one that "borrows" the screen resource of an ancestor-which makes it lighter.Can anybody explain What native screen resource is and how it is borrowed?
2)I read that SWT uses native widgets and how can it be better than swing?If it is in what way?

Use Swing for new projects. AWT is the rendering layer underneath Swing in many cases, and AWT provides utility things like Graphics. SWT is an alternative to Swing which used more native rendering, but actually with Java 6, Swing is using a lot of native rendering.
Fire up NetBeans and use Matisse. Build an application. Run it under Windows, and then under Linux, and then realize how great it is.

Hibernate problem..... using projection and conjunction together..

hi all ,
can we use projection and conjunction together??
i want to execute a query like this..
select column_1 , column_2 from table_name where column_1 like '%a' ;

hi ian
you could also try verifying if the jar libraries containing your Document and Paragraph classes are defined in your class path OR if you are using an IDE, did you include that under your LIbraries?
The previous suggestion below also is a stop-gap to the library inclusion problem.
Hope that helps

Using Concat and Distinct together

SELECT 'SELECT ' || DISTINCT COLUMN || ' FROM DUAL UNION ALL '
FROM TABLE;Whenever you have a problem, please post CREATE TABLE and INSERT statments for a little sample data, and the results you want from that data.
The example you posted has so many mistakes, it's hard to know what you're trying to do.
COLUMN, DISTINCT and TABLE are all Oracle keywords, and shouldn't be used for actual columnor table names, and using them for aliases is just asking for trouble.
When using SELECT DISTINCT, the keyword DISTINCT must come immediately after SELECT.
If you want to assign an alias to a column, it must be at the very end of the expression that defines the column. You can't assign an alias to part of an expression. If you want to do that, use a sub-query.
Here's a query that uses both SELECT DISTINCT and ||:
SELECT DISTINCT

Using Airport And Ethernet Together

Having read Christopher Breen's solution to using Airport and Ethernet together,
http://www.macworld.com/weblogs/mac911/2006/10/airportswitch/index.php
I am still wondering if this can apply to my situation. I have an Airport Exteme BS distributing the wireless signal on it's own node. Nothing is physically connected to the BS except an ethernet cable running to a hub which is connected to the cable modem. While my ISP service isn't supplying service faster than Airport will manage, no problem...but, I would like to have the advantage ethernet networking between my machines for all the advantages that ethernet speed can bring to that situation.
My connection to the internet is from WAN from the cable modem. I have an ethernet connection from the BS that I can run a cable back to say, an iBook. Will this work? I want wireless internet, but ethernet for machine to machine networking.
JAL
iBook G3/500 G4/Dual 450 Mac OS X (10.4)
iBook G3/500 G4/Dual 450 Mac OS X (10.4)

Helpful response, but I am uncertain this is what I am after. First, the hub is at the other end of the house, inconvenient to run a cable to it in this way. Presently, "Distribute IP Addresses" is turned off. This is way it had to be set since the AEBS is on a separate node. I just wonder why I can't run a cable from the AEBS LAN port back to the iBook. Looking for best possible speed when networking from my studio G4 while keeping the wireless internet setting.
Any reason making the config the way I am imagining will not work?

Using swingworker and invokeLater together

Hi all�
Anyone knows if there is an appropiate way to use the worker thread through SwingWorker and invokeLater together?
It maybe sounds a bit weird but I have to launch a thread from EDT with invokeLater utility, otherwise i'd get a block state between EDT and my own thread. In other hand, I need to use SwingWorker utility for try to avoid the awful effect of loosing the visual desktop while transaction is proccesing.
Obviously, if i use SwingWorker and inside doInBackGorund method, launch my thread with invokeLater it doesnt make any sense since the worker do its work in differents threads...
I'd appreciate any help concerning this problem.

Hi Albert,
I believe that this code might help:

Using generics and J2SE together with JSF

Hi
Has anybody experience with using JSF together with J2SE 1.5? Especially generics? I would like to use generics and other improvements from J2SE in the model objects.
Thnaks in advance ... Rick

JSF 1.1 is specified for J2SE 5, and the new specification (JSF 1.2 and JSP 2.1) does not include generics.
If you are talking in terms of ValueBindings or MethodBindings, there really isn't any point since the implementation could only make the cast for you; and it would still not be able to garuantee type safety (the only reason to use generics).
That's not to say you couldn't use generics in your own development, but I don't think you will see generics incorporated into the specification any time soon.

Using Struts and JSTL together

I have
<html:form action="xy.do">
<c:set var="name" value="shalik"/>
<html:text property="name" value="<c:out value="${name}"/>"/>
</html:form>
How could I put data stored in ${name} to show in the text
Also, is there a shorter way to access java variables using jstl core
I would not want to do
<input type="text" name="name" value="<c:out value="${name}"/>"/>
which works, because I have to use struts

No you can't include tags as attributes to other tags.
Yes, you can definitely use the Struts and JSTL together.
If you want to use EL expressions with the struts tags, it depends on your server.
If you have a JSP2.0 container (eg Tomcat 5) its no problem at all. You can use the EL expressions directly with the standard struts tags.
For a JSP1.2 container, there are specifically written struts-el tags. They let you use EL expressions instead of <%= %> expressions
<c:set var="name" value="shalik"/>
<html:text property="name" value="${name}"/>The struts-el tags only have a subset of the struts tags. It is intended for use with the JSTL. For instance the c:if tag easily replaces a lot of the logic conditional ones (equal, lessThan, etc etc)
The tags are available as part of the standard struts download in the contrib directory.
However for what you seem to be wanting to do, wouldn't it be more struts-like to have an action that specifically populates the action form, and just have
<html:text property="name"/>
The value would then be automagically populated from the form bean.
Hope this helps,

Ugly code.
Bulk processing does what in PL? One and one thing only. It reduces context switching between the PL and SQL engines. That is it. Nothing more. It is not magic that increases performance. And there is a penalty to pay for the reduction in context switching - memory. Very expensive PGA memory.
To reduce the context switches, bigger chunks of data are passed between the PL and SQL engines. You have coded a single fetch for all the rows from the cursor. All that data collected from the SQL engine has to be stored in the PL engine. This requires memory. The more rows, the more memory. And the memory used is dedicated non-shared server memory. The worse kind to use on a server where resources need to be shared in order for the server to scale.
Use the LIMIT clause. That controls how many rows are fetched. And thus you manage just how much memory is consumed.
And why the incremental commit? What do you think you are achieving with that? Except consuming more resources by doing more commits.. not to mention risking data integrity as this process can now fail and result in only partial changes. And only changing some of the rows when you need to change all the rows is corrupting the data in the database in my book.
Also, why use PL at all? Surely you can do a INSERT into <table1> SELECT .. FROM <table2>,<table3> WHERE ...
And with this, you can also use parallel processing (DML). You can use direct path inserts. You do not need a single byte of PL engine code or memory. You do not have to ship data between the PL and SQL engines. What you now have is fast performing code that can scale.

Swings and networking together???

hi can anyone help me out with this. I have made a console based client and server connection...now i want to convert it into GUI based using swings. The objective is to send text-textarea from one side to the text area of another side.....and also how to convert the strings into bytes? Thanks

Look at the documentation for String.getBytes(encoding).
For example
byte[] bytesFromString = "Hello".getByte("UTF-8");

I am very new at using USRP-2943R and PXIe-8135, 5652, 5601, 5622, 8374.
Literally, I don't have any idea how to use above USRP and PXIe together.
Now, I connected USRP-2943R to PXIe-8374 which is linked with PXIe-8135.
I want to make QPSK example with theses equipments by using LABVIEW.
But the problem is there is no manual how to use like that.(or I coun't find it yet. XD)
Could someone give me any comment and manuals to use these equipments for making basic communication system?
Please gents and ladies, give me any comment.
My e-mail : [email protected]
Thank you so much your reding.
