Sixteenth Hour

8×8 cubicles,
fagged faces,
hokey smiles,
killed my nerves..
at sixteenth hour..
I became a wind..
now.. awaiting to break away..
from this man-made labyrinth..

Java Swing GUI design with FREE tools

Jayanath — Sun, 01 May 2011 02:01:52 +0000

When we build a Java Swing application, the GUI design could end up being a very time consuming process. The perfectly aligned components of a data entry form may look awful on a screen with a different resolution. Aligning buttons with proper spacing could become a never ending struggle.

However many IDEs like Netbeans have nice WYSIWYG GUI builders to help developers to easily build Swing based screens. But everything comes with a price . If we use those GUI builders we could end up having IDE generated code with comments like:

/**
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
*/

The WARNING sign reminds the consequences that we will have to face by using an IDE to build the Swing screens. These consequences may include but not limited to the points specified below.

The generated code should not be edited and we have to live with what ever the code that IDE throws at us
Even a small change to the GUI design requires to regenerate the entire GUI code for that screen. This may require to use the same IDE version to maintain the integrity of the code. Also this may require lot more testing as the IDE is directly modifying the existing code.
Having IDE generated code intertwined with developer code may lead to maintenance problems in future, even though this could be minimized by separating generated code as much as possible

JGoodies forms library and Abeille forms designer are two great tools (of course, they are free ) that we could use to step away from the above mentioned issues. Abeille form designer works as a GUI front end for the JGoodies forms library and it generates the GUI design as an XML file. JGoodies also has ButtonBarFactory that we can use to create a nicely aligned button panel.

Now let’s create a simple screen to capture user information using Abeille form designer. We will use Abeille version 2.1.0 M1. The user interface of this tool is very intuitive and you will easily figure out the things.

Steps to follow:

Download and unzip the Abeille form designer and run the designer.jar
Create a new project by selecting “File –> New Project”
Go to Tools–>Preferences and click the Store forms as XML check box on the Projects tab.
Create a new form by selecting “File–>New Form”
The resulted grid can be easily modified by using the buttons at the top. All the buttons have tool tips that are very helpful and self explanatory.
Change the size of the columns and rows of the grid by dragging from the two pegs provided in each axis (figure 1)
The components at the left tool box does not work like typical drag-and-drop components. Click on any component on the tool box and then click on a cell of the grid to add the component to the grid
Name the components accordingly as we are going to use this name to reference the components in the code
Click on the label “First Name” and then change the column properties using the collapsing menus at the right side. (figure 2)

Here is a screen shot of the form once we add all the components.

[Figure 1]

The two circles on each axis of the grid shows the pegs that can be used to change the column and row sizes.

The circle at the bottom shows the project name and absolute path.

Note that the “countryCombo” and “Button bar” are just JLabel components. Later we will replace them with a JComboBox and a JPanel with JButtons respectively.

[Figure 2]

By setting the column size to “Component” the size automatically adjust with the component length.

We will do this to the column with the labels.

There are lot more features in this tool and it is best to read the documentation to learn more about them.

Now let’s create a Java project and use the XML file generated by Abeille tool and JGoodies Forms library to build our form. Before proceed, make sure to add all the required jar files to the project class path. Class path of my project looks like below(figure 3)

[Figure 3]

Below is the code to use our form in the application. You may notice following things in this code.

Cleaner code, NO IDE generated code intertwined with the application code.
We have the liberty to swap any component in the GUI panel with any desired component
It is easy to reuse the GUI components even in any other class, only thing we have to do is to read the form xml from that class
If we have to make a small change (add a new label, change spacing etc.) we can do it in Abeille form designer. There is nothing to change in the Java code, hence it requires no additional testing to test the existing features.
ButtonBarFactory takes care of the spacing and sizing of the buttons

/**

public JPanel populateMainPanel(){
//the FormPanel derived from JPanel
FormPanel mainPanel = new FormPanel("userInfo.xml");

//let's create a combo box with values and add it to the panel
String [] countries = new String []{"Sri Lanka", "USA", "China"};
JComboBox countryCombo = new JComboBox(countries);

//now we can simply swap the label that we put in the place where
//we need to set the actual combo box. Likewise we can swap any component
//on the panel.
mainPanel.getFormAccessor().replaceBean(ID_COUNTRYCOMBO, countryCombo);

//let's set some default values to other components
//this shows you how to access any of the component
//the API supports many default component types
JTextField street1 = mainPanel.getTextField(ID_STREET1);
street1.setText("Patroon Drive");
JRadioButton mRadioBtn = mainPanel.getRadioButton(ID_MALERADIOBTN);
mRadioBtn.setSelected(true);

//we will use the ButtonBarFactory to generate our buttons panel
//this JGoodies API provides many useful methods.
//first, let's create our buttons
JButton okBtn = new JButton("OK");
JButton canBtn = new JButton("Cancel");
JButton regBtn = new JButton("Register me later");
//now generate the button bar panel
JPanel btnPanel = ButtonBarFactory.buildCenteredBar(okBtn, canBtn, regBtn);
//next, we can replace the buttonBar label with this new button bar panel
mainPanel.getFormAccessor().replaceBean(ID_BUTTONBAR, btnPanel);

//finally, let's add a nice boarder to our panel
Border etchBorder = BorderFactory.createEtchedBorder(EtchedBorder.LOWERED);
Border titleBorder = BorderFactory.createTitledBorder(etchBorder, "User Information Form");
mainPanel.setBorder(titleBorder);

return mainPanel;
}
/**

public static void main(String[] args) {
UserInfo uInfo = new UserInfo();
JFrame frame = new JFrame("Panel created using Abeille form designer");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(uInfo.populateMainPanel());
frame.pack();
frame.setVisible(true);
}

}

Here is the what we see when we run the application.(figure 4)

[Figure 4]

Note the buttons are evenly spaced and properly sized.

To give a comparison I created the same UI using Netbeans 7.0 GUI Builder. Figure 5 shows the screen generated using GUI builder of the IDE.

[Figure 5]

Netbeans 7.0 GUI Builder is very easy to use and I created the above screen in few minutes. However look at the code behind this screen and you will realize how hard it is to maintain such code.

I made it folded as it is very lengthy and I’m sure that you will not read it till end Click below to open the folded code.

Conclusion

The IDEs are very capable of generating Swing based screens and they are great in prototyping and building small Swing applications. Unlike the IDEs the Abeille Form Designer externalizes the GUI design code in to an XML file hence allow to maintain cleaner and more maintainable code.

There are other powerful Swing GUI building tools available but they are not FREE. If possible I would use something like JFormDesigner but the license fee is 160 USD per user. Hence I would rather use Abeille Form Designer when possible.

After a long time

Jayanath — Sun, 31 Jan 2010 03:31:21 +0000

Year 2009 ended as an eventful year. We had few road trips and got a chance to travel through many states.

Trip One: Willimantic,Connecticut -> Baltimore, Maryland -> Washington DC -> Fall Creek Fall, Tenessee -> Drive over Great Smokey Mountains -> Polar bears & Pandas, Mempis, -> Village Creek Camping, Arkansas -> Norman, Oklahoma and Cowboys

Trip Two: Norman,Oklahoma -> Rio Grande rail road, Colorado -> Santafe, New Mexico -> Sandia Peak Tramway, New Mexico

Trip Three: Norman Oklahoma ->St.Louis, Missouri ->Columbus,Ohio -> Albany, New York.

While we were on the road,

As predicted, Google released the Chrome OS
Google released the first Google branded smartphone, Nexus One
Few e readers came to market like Nuke and few days back , on Jan 27th 2010 Apple iPad came out with lots of bells and wistles

Also I got a chance to buy a nice little internet radio, Logitech Squeezebox Radio. It is small yet powerful, feature rich.. well worth for every $ I paid.

Dependence on Google

Jayanath — Thu, 09 Jul 2009 18:08:18 +0000

“Google Gmail, Google Chrome browser, Google Calendar… very soon a Google OS.. how easy it is to find everything in one place from one company…. but..”

I started to use Gmail somewhere in mid 2005 and it became my primary email by simply replacing Yahoo mail. Hotmail, AOL and Yahoo are just the history for me as well as for many millions out there. In late 2008 Google Chrome came in to the picture with its unique and sleek interface. Even though I was widely using Firefox I started to use Chrome as an alternative browser. After few months, Now I’m typing this post using Chrome as my default browser. I’m not using most of the Firefox plugins and addons so I felt like I found yet another browser with slightly better performance from Google.

About few days back Google announced that they will be taking their next step by introducing a new operating system, Google Chrome OS. Yes there were enough and more rumours about a Google OS well before they introduced the Androide. I think it will be great (well.. not for Microsoft and Apple ) as it’s going to be a free and open source product based on Linux kernel.

While eagerly waiting to try out this new OS, I started to realize that one day Im going to be a total dependent of this gigantic company, “Google” in the cyber space. I know that I’m not alone and there are many millions who followed the same path, unintentionally. A few questions would reveal this dependence.

What is your primary email : Gmail
Any other email accounts : Well, gmail is the only email address that I used for many years. It has all my conversations.
What is your default browser : Google Chrome, it does the job and I’m happy with that
Operating System : Google Chrome OS (not as yet, but it might be the answer in the future)
Using google calendar : Yeh.. it is really nice
Any google apps : Of course

This means, Google has all my information and if needed it could disable my account, use all my information and simply leave me nothing if I don’t have any backups locally.

The bottom line is we are unintentionally funnelling our information in to one single (may be two, if we consider the Facebook owned by Microsoft ) company and it is yet another giant with its best interests on profits at the end.

Back to Arch Linux: Simply the best

Jayanath — Wed, 20 May 2009 21:00:31 +0000

When I bought my Lenovo R61 it came with a pre installed Vista Basic edition. I replaced Vista with various linux flavours like openSUSE, Fedora, Debian ,CentOS etc. Finally I found Arch Linux and I think its the best distro for me. I had Arch as my main OS and had windowsXP on a Virtual Machine till end of Feb, 09. However I had to install windowsXP by removing Arch due to some software packages that demanded nothing but Windows. This time I kept some free space to set up a dual boot. About a week back I managed to do a fresh Arch Linux installation.

For a change, I picked up KDE 4.2 instead of the usual GNOME . I used it for few days and I felt like I’m missing something, the clean and simple GNOME . The all new KDE 4.2 is appealing but I think its not for me. I tried KDE even with some other distros like Kubuntu, OpenSUSE but always wanted to go back to GNOME.

I enjoyed setting up the new Arch and felt very happy about the improvements that it gained during the past few months.

Few things that are noteworthy.

Wireless is working flowlessly. Back then I had lot of problems with my AR5212 card and madwifi drivers. This time I’m using ath5k and my wireless connection is even faster than it is in WinXP.
Thinkpad hot keys are working out of the box ( volume controllers, battery meter etc. )
ALSA sound is working perfectly with no cranky noice. I had to adjust the PCM volume (in alsamixer) to a level such that gain is zero to get the best sound quality. Last time I replaced ALSA with OSS as ALSA made lot of noice.

At the same time I had a look in to OS x86 project. I would love to try that on a separate machine if I get a chance.

Listen to your documents with Text To Speech

Jayanath — Tue, 05 May 2009 04:20:52 +0000

Text To Speech (TTS) is a default feature in myriad of electronic devices including portable GPS systems. TTS on the computer is very useful in reviewing documents. Reading through the same document over and over may not help much in identifying errors and missing punctuations, specially if you are the writer. TTS comes in handy at this point.

Hope the following would help someone to try out and enjoy TTS on WinXP.

Check the availability of Text To Speech feature:

Open Start–>Control Panel–>Speech.
Go to the Text To Speech Tab.
Verify the availability of voice engines from the drop down list.

Grab a good Natural Voice Engine:

The microsoft default voice engins are nearly useless in real world. You will realize this, soon after hearing the sample voice

I found some good free voice engines from Cepstral. You can try them for free.

Their free version does not expire. However it promotes you to purchase the licensed version in every minute or so. Of course it is annoying enough to either purchase it or to get rid of it The right tool to remove the message (The License key ) is available for $29.99 on there web site, if it is affordable for you.

After downloading and installing the Cepstral voice you can set it as the default voice by using the same Start–>Control Panel–>Speech window.

The Cepstral comes with a SwiftTalker, a text editor with integrated TTS feature. It is very usefull to quick edits and reviews.

Check the Cepstral menu on Start–>Programs–>Cepstral for SwiftTalker.

Use the TTS on Adobe Reader:

Go to Documents–>Accessibility Setup Assistant and follow the instructions to setup the TTS options.
Go to Edit–>Preferences.
Select Reading from the Categories list
On the Read Out Loud Options section, remove the check mark of Use default voice and select the new voice engine that we installed from the voice drop down list.
Go to View>Read Out Loud, enable the TTS function. This will also enable the other related sub menus to start, pause and stop.

Now you can listen to your PDF document.

GM to Discontinue Pontiac..

Jayanath — Mon, 27 Apr 2009 16:10:27 +0000

“The President of General Motors announced Monday his plans to discontinue production of its celebrated Pontiac brand and cut 21,000 factory jobs by next year as part of a massive restructuring effort to get more government aid.” - Los Angeles Times

Pontiac G6 is a great car to drive ( well .. not to own by my self .. as it will quickly eat up my money for GAS ).

I got a chance to drive this beast on I-70 from Kansas city airport to Manhattan,KS and easily hit 130 mph without even feeling the speed. It was an awesome driving experience !!.

XMind with PDFCreator

Jayanath — Sat, 18 Apr 2009 15:17:01 +0000

With

As a visual person, I always rely on drawing diagrams when ever I try to learn something. Mind Maps (back then I didn’t know this term ) were very helpful during my undergrads and I used them a lot for tutoring as well. Few months back I found XMind, a wonderful tool for mind mapping. The free version is more than enough for studies with plenty of features. However there was a one limitation with the free version. It does not allow to save the mind maps in PDF format. This feature is only available in XMinde Pro version.

Fortunately I found PDFCreator, yet another free and open source tool. Once installed it acts as a pseudo printer. You can set it as your default printer and when ever you send anything to print, it will generate a nice PDF file for you.

With this approach I managed to get the maximum usage from my favourite mind mapping tool.

File names and Windows

Jayanath — Thu, 26 Mar 2009 01:02:09 +0000

Recently I was configuring a new application on Windows XP and found that the configuration files could not handle the folder paths with spaces. I couldn’t get away with escape characters. However I found a solution in Windows itself after a small search.

There is an option for the famous dir command to display the short names generated by the system for non -8dot3 file names.

Life… its beauty…

Jayanath — Mon, 23 Mar 2009 15:19:00 +0000

Life…
The uncertainty..
That’s its beauty..
The turns and twists.. rises and falls
Least you expect.. The harder it hits..
Never you could know…
The next turn of its flow..
Faster you run..
More you would miss.. the true sense of life..
Slow down a bit..
Release the tense and grip..
A moment of silence..
A moment of peace..
Unleashes the wisdom..
You never meant to reach..
