About tooltips in java swing

Hi friens,
I am writing a 2D graph swing program for displatying graphs on the browsers. I am drawing graphs directly on the main content pane with out adding any controls. I want to show a tool tip with the value of X, Y coordinates when user places the pointer on a point on the graph. I am able to add tooltips for controls like textbox, button , label etc. but not able to add to the main content pane. please help me out.
thanx
bye
rpk

We do this by adding a MouseMotionListener that calls setToolTipText() on the parent component based on the current X,Y location of the mouse pointer. E.g. we're normally drawing 2D graphics objects, so using the contains() methods on those objects as we draw them on a JPanel we calculate which object the mouse is contained within and set the tooltip text on the JPanel accordingly.

About dll from java swing

Hi,
I hava class (send sms from java) in dll - ActiveXComponent type, his name: SMSCom
dll name: SMSSender
that get in his constractor: (in VB I wrote this)
SMSObj.password = password;
SMSObj.Username = user;
SMSObj.Source = phone;with this code I'm connect to the dll file and his object, but
I don't know how to give this object this parameters.
ActiveXComponent ax = new ActiveXComponent("SMSCom.SMSSender");
Dispatch SMSObj = (Dispatch) ax.getObject();Thanks alot for any help :)

Thank you so moch, you helped me alot!!!!!
I you coul'd help me with last little thing I'll be happy:
but I have error, it is not attached to your help, the error link to this line
(I have jacob.dll +jacob.jar)

What is difference between C# Gzip and Java swing GZIPOutputStream?

Hi All,
I have a Java swing tool where i can compress file inputs and we have C# tool.
I am using GZIPOutputStream to compress the stream .
I found the difference between C# and Java Gzip compression while a compressing a file (temp.gif ) -
After Compression of temp.gif file in C# - compressed file size increased
while in java i found a 2% percentage of compression of data.
Could you please tell me , can i achieve same output in Java as compared to C# using GZIPOutputStream ?
Thank a lot in advance.

797957 wrote:
Does java provides a better compression than C#?no idea, i don't do c# programming. and, your question is most likely really: "does java default to a higher compression level than c#".
Btw what is faster compression vs. better compression?meaning, does the code spend more time/effort trying to compress the data (slower but better compression) or less time/effort trying to compress the data (faster but worse compression). most compression algorithms allow you to control this tradeoff depending on whether you care more about cpu time or disk/memory space.

PL/SQL and Java Swing interface

Everybody in this forum knows that Oracle is the best database around
with many functionalities, stability, performance, etc. We also know
that PL/SQL is a great language to manipulate information directly
in the database with many built in functions, OOP capability,
transaction control, among other features. Today an application that
manipulates information, which needs user interface, requires components
to be developed using different technologies and normally running in
different servers or machines. For example, the interface is done using
a dynamic HTML generator like JSP, PHP, PL/SQL Web Toolkit, etc.
This page is executed in an application server like Oracle iAS or
Tomcat, just to name two, which in turn access a database like Oracle to
build the HTML. Also rich clients like Java applets require an intermediate
server to access the database (through servlets for example) although
it is possible to access the database directly but with security issues.
Another problem with this is that complexity increases a lot, many
technologies, skills and places to maintain code which leads to a greater
failure probability. Also, an application is constantly evolving, new
calculations are added, new tables, changed columns. If you have an
application with product code for example and you need to increase its
size, you need to change it in the database, search for all occurrences
of it in the middle-tier code and perhaps adjust interfaces. Normally
there is no direct dependency among the tier components. On another
issue, many application interfaces today are based on HTML which doesn't
have interactive capabilities like rich-client interfaces. Although it
is possible to simulate many GUI widgets with JavaScript and DHTML, it is
far from the interactive level we can accomplish in rich clients like
Java Swing, Flash MX, Win32, etc. HTML is also a "tag-based" language
originally created to publish documents so even small pages require
many bytes to be transmitted, far beyond of what we see on the screen.
Even in fast networks you have a delay time to wait the page to be
loaded. Another issue, the database is in general the central location
for all kinds of data. Most applications relies on it for security,
transaction and availability. My proposal is to use Oracle as the
central location for interface, processing and data. With this approach
we can create not only the data manipulation procedures in the database,
but procedures that also control and manage user interfaces. Having
a Oracle database as the central location for all components has many
advantages:
- Unique point of maintenance, backup and restore
- Integrated database security
- One language for everything, PL/SQL or Java (even both if desired)
- Inherited database cache, transaction and processing optimizations
- Direct access to the database dictionary
- Application runs on Oracle which has support for many platforms.
- Transparent use of parallel processing, clusters and future
background technologies
Regarding the interface, I already created a Java applet renderer
which receives instructions from the database on how to create GUI
objects and how to respond to events. The applet is only 8kb and can
render any Swing or AWT object/event. The communication is done
through HTTP or HTTPS using Oracles's MOD_PLSQL included in the Apache
HTTP server which comes with the database or application server (iAS).
I am also creating a database framework and APIs in PL/SQL to
create and manipulate the client interface. The applet startup is
very fast because it is very small, you don't need to download large
classes with the client interface. Execution is done "on-demand"
according to instructions received from the database. The instructions
are very optimized in terms of network bandwidth and based on preliminary
tests it can be up to 1/10 of a similar HTML screen. Less network usage
means faster response and means that even low speed connections will
have a good performance (a future development can be to use this in
wireless devices like PDAs e even cell phones, just an idea for now).
The applet can also be executed standalone by using Java Web Start.
With this approach no business code, except the interface, is executed
on the client. This means that alterations in the application are
dynamically reflected in the client, no need to "re-download" the
application. Events are transmitted when required only so network
usage is minimized. It is also possible to establish triggering
events to further reduce network usage. Since the protocol used is
HTTP (which is stateless), the database framework I am creating will
be responsible to maintain the state of connections, variables, locks
and session information, so the developer don't need to worry about it.
The framework will have many layers, from communication up to
application so there will be pre-built functions to handle queries,
pagination, lock, mail, log, etc. The final objective is to have a
rich client application integrated into the database with minimum
programming and maintenance requirements, not forgetting customization
capabilities. Below is a very small example of what can de done. A
desktop with two windows, each window with two fields, a button with an
image to switch the values, and events to convert the typed text when
leaving the field or double-clicking it. The "leave" event also has an
optimization to only be triggered when the text changes. I am still
developing the framework and adjusting the renderer but I think that all
technical barriers were transposed by now. The framework is still in
the early stages, my guess is that only 5% is done so far. As a future
development even an IDE can be created so we have a graphical environment
do develop applications. I am willing to share this with the PL/SQL
community and listen to ideas and comments.
Example:
create or replace procedure demo1 (
jre_version in varchar2 := '1.4.2_01',
debug_info in varchar2 := 'false',
compress_buffer in varchar2 := 'false',

Is it sound like Oracle Portal?
But you want to save a layer 9iAS.
Basically, that was the WebDB.(Oracle changed the name to Portal when version 3.0)
Over all, I agree with you.

Problem with java swing button and loop

Problem with java swing button and loop
I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
When I click on start button it must do next:
Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
And when I click on stop button it must do next:
Start button must set enabled and selected and Stop button must set disenabled.
Field status is set to 0.
This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
There is java code, so you can get better picture:
/** start button */
public void gStart_ActionEvents() {
try {
ivjGStart.setEnabled(false);
ivjGStop.setEnabled(true);
ivjGStop.setSelected(true);
getJTextPane1().setText("Program is running ...");
Status = 1;
} catch (Exception e) {}
/** stop button */
public void gStop_ActionEvents() {
try {
ivjGStart.setEnabled(true);
ivjGStart.setSelected(true);
ivjGStop.setEnabled(false);
getJTextPane1().setText("Program is NOT running ...");
Status = 0;
} catch (Exception e) {
/** procedure IzvajajNeprekinjeno() */
public void IzvajajNeprekinjeno() { //RunLoop
try {
int zamik = 2000; //delay
do {
Thread.sleep(zamik);
PreberiDat(); //procedure
} while (Status == 1);
} catch (Exception e) {
So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
Any help will be appreciated.
Best regards,
Tomi

This is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
Since java is task-based this will happen if you do like this:
1. Button "Start" is pressed. Thread running: GUI_Thread
2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
5. Call PreberiDat(). Thread running: GUI_Thread
6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.

How Hard is it to program in Java.Swing

Hi
I wanted to program using java.swing component but i don't have any idea where i should start.
I have been programming in java using java.Awt
and i can do simple array programing.
So how hard is it, and Where should i start learning java.swing. Ps I don't know anything about Swing, I don't even know what it is.
Thanks you

Hi
As the previous guy said it is quite easy, and that link should teach you the basics. What I want to remind you of is that Swing uses up more memory when run. But it also have a few nicer extra goodies that make coding a little bit easier. Have fun with it.

Expandable Menu in Java Swing app

Hello JFriends,
is it possible to create a expandable menu in java swing app? I am thinking of something like menu in MS Visio: http://img32.imageshack.us/i/menuip.jpg/
It works like that: When user click on a bar it expands (with nice animation) and shows containing components.
Or maybye there are components like that?
Thanks in advance for Your reply and please forgive me if my english is bad.
JRegards :-)

Yes, such constructs are possible. There isn't a pre-made component exactly like that. The NetBeans IDE has a Window - named Palette - that's very similar. The code is open source.
You can read about Java menus here:

Draggable buttons in Java Swing

Hi,
I want to develop an application in Java Swing. The application I am going to develop is an application for developing other applications. I want my application to include a button which also acts as a drag and drop UI element. For example, I want my application to include a button for adding a picture. There are 4 buttons of different pictures. If a user wants to add a picture he can either click on one of these buttons and that picture will be added somewhere on the screen or dragging this button and drop it and that picture will be added where he dropped that button.
Could anyone please tell me
1. If I can develop an application which includes Drag and Drop UI element if I develop it in Java Swing
2. If a button (or other UI element) can act as both a button and a drag and drop element if I develop my application in Java Swing
3.
Could you please tell me where I can find some screenshots of applications which has been developed in Java Swing? I am not familiar with this program and I am not that good at programming, so I would like to get some impression of how it might look like.
Thanks in advanced

1. the good thing about Swing is that it is very flexible and with clever programming you can do just about anything. The problem is that depending on your requirements, this could require a great deal of programming that can be very hard to implement such that it works properly on all popular platforms (windows, linux, mac).
2. see 1.
3. Swing applications are "skinnable", you can give them a great number of different appearances. The default is to give the application a system look and feel, so they look pretty much like any other application for that platform. This means that when you run your application on Windows, it will look like a Windows application, if you run it on a Mac it will look like a Mac application, etc.
I am not familiar with this program and I am not that good at programmingThat is quite a problem, because Swing is not the easiest API around. It requires a solid knowledge of Java and Object Oriented Programming in general as the entire API is based heavily on OOP concepts. To get a better idea of Swing, read through the Swing tutorial here:

Java swing app distribution & setup

We developed a java swing standalone app. How you guys distribute this kind app to end users if they know little about app setup(like data entry clerks).
We like to generate an executable file bundling the app and JRE for our clients. They just run this executable to detect if there is no JRE on the local machine then install it, and then install the app and setup all environment variables. Is there any tool to do this?
Thanks.

If all you need to do is package the JRE with the app and install, then an installation tool like ZeroG InstallAnywhere would be a very good solution.
If all you need to package, install and automatically deploy updates, you can probably cobble together an installer that uses Java Web Start. Note that in addition to the JRE, you will also need ensure that Web Start is installed.
If you need to package, install, update, rollback, report, monitor, receive error alerts, and otherwise manage the application, you probably need DeployDirector, in which case, I encourage you to evaluate DeployDirector at http://www.sitraka.com/software/deploydirector/
And yes, both InstallAnywhere and DeployDirector will allow you to deploy and manage a client-side app that communicates with a database and reads and writes from files on the client -- neither of these tools enforce the sandbox. Java Web Start will require you to either sign the application, or or use the JNLP API.

Opening browser window from Java Swing

Hi
I am trying to open
1) a word document on the click of a button from a Java-Swing based application running only on windows based system.
Currently the code uses 'rundll' and calls 'a.doc'
it requires that the application be installed and run only from a specific location in the windows' system.
i would like to modify the code in one of the following ways
1) open the word doc irrespective of its location and that of the executable jar which is trying to open this file
2) upload the word document to a website and direct the application to open that webpage on button click, etc
i believe that the latter may be simple but i do not have any idea about how to go about it
i would appreciate some guidance about it.

JAVA / SWING apps, font AA / LaF KDE 4.3

Hi Everyone,
I know the title is terrible, but here is my problem:
I am using Netbeans for most of my development projects. I am very happy with it; however, the look and feel of Netbeans (and most other Java apps, such as FreeMind for example) is appalling and does not integrate into my KDE 4.3 desktop at all. I understand that you can start netbeans with certain options to change the look and feel to GTK, but the fonts still look jagged.
I followed this forum post http://bbs.archlinux.org/viewtopic.php?id=72892 and tried to set the JRE / JAVA options globally, so that all java apps start with GTK laf and AA. However, non of the methods described work / netbeans overrides them (?).
But really, the biggest problem are the ugly fonts. Java / SWING apps do not seem to recognize my KDE settings for AA and font style at all. And non of the Cl options work to fix it.
Does anyone have any tips or tricks to fix any of these issues I am having with the combination Java / Swing / KDE / NB?
Running:
Archlinux (duh)
KDE 4.3 / qt-gtk-engine
sun-jdk 1.6uX
Netbeans 6.7.1

I added what I knew about improving Sun java fonts to the wiki: http://wiki.archlinux.org/index.php/Jav … _-_Sun_JRE. You may want to try other fonts than B&H's Lucida. See the section in the wiki article about changing the default fonts by editing 'fontconfig.properties'.

How to create a semi circuler slider using java swing or awt

I am trying to create a Jslider like thing but in semicirculer shape. Thanks in advance for providing any help.

Is it possible to create such UI in java swing?Just to further illustrate, Swing only provides the raw foundation you need to be able to build a GUI. With the stock components you can create static user interfaces with standard controls. If you want to go further, you need to either find a component that somebody else already wrote, or you go into custom painting as previous posters suggested. To do an animating component for example, you would need all the frames as BufferedImage objects and you would combine custom painting with a Swing timer to update the displayed frame at a specified framerate.
if you search for "java swing animation" using google, I'm sure you can find the examples you need. And here is the trail about swing timers:

Upgrade Java Swing Project

Hi Everyone,
I am looking forward for some guidance from all you guys here.
I have been assigned the work of upgrading Java Swing project. The upgrading also involved some improvements in look and feel of the tool.
Currently the tool looks very simple/basic and needs some good over-haul.
As basically I am a J2EE guy, I dont have much idea about the Swing Open-source API's that I can utilize for the same.
If anyone has good idea about the API's that can be utilized or suggestions for the improvement of the tool look wise then please let me know.
Thanks,
Gaurav

..some themes like metal(being used currently), Windows and nimbus.
I implemented all these themes one by one in the project, but not sure if I can use any of these themes and extend them in some ways to look like the mock-up.
The Synth Look and Feel.
"Creating a custom look and feel, or modifying an existing one, can be a daunting task. The <a href="http://download.oracle.com/javase/7/docs/api/javax/swing/plaf/synth/package-summary.html">javax.swing.plaf.synth</a> package can be used to create a custom look and feel with much less effort. You can create a Synth look and feel either programatically or through the use of an external XML file. The discussion below is devoted to the creation of a Synth look and feel using an external XML file. Creating a Synth L&F programatically is discussed in the API documentation."
There are also a number of existing custom PLAFs. E.G. See this excellent summary at SO on the thread Look and feel in java.
What will you suggest me :)<ul>
<li>When in doubt, try it.
