Happy Moments...

Couple of minutes ago I received the mail from the Google Open Source Programs Team announcing the final results of Google Summer of Code 2010. I am so happy that I got through the final evaluations :-)

Simply it was a lifetime experience and opened me new paths towards achieving many new goals... My special thanks to my mentors Sy Haas and Dr.Paul Biondich for their immense support and guidance throughout the summer.. All developers of OpenMRS were very much motivating and inspiring me towards contributing to open source... Thank you very much everyone... I would like to thank all my teachers and friends for their support in every way...

Just wanted to share my happy moments...

I will be writing more about my GSoC experience soon...

Thank you every one...

Reaching the Final Evaluations of Google Summer of Code 2010

Last week was the final week of Google Summer of Code 2010 and I spent it in writing module documentation, documenting the code and completing few enhancements. I did some refactoring to the code - introducing a new class FlowsheetPanel to have the user interface generation code (earlier it was inside the onModuleLoad() of the Flowsheet EntryPoint class). This idea was suggested by my mentor Sy, to make the code re-usable. The user interface generation code was put inside the onRender() of the FlowsheetPanel class, which is a subclass of LayoutContainer. In the Flowsheet EntryPoint class, new instance of FlowsheetPanel was simply created and added to the root panel.

Searching for observations based on ConceptName was handled using the default filtering options in the Grid widget earlier; since that way is only known by the users who read the documentation or the users who explore the module, I added the search box on the on top of the observations grid, visible to all users. The image below show's the new search box:

Module documentation for the Flowsheet module was created in the wiki page located at : http://openmrs.org/wiki/Flowsheet_Module. This wiki page contains the details of the module, especially the features of the Flowsheet module and how to use them. Also I have provided link for other resources related to the module.

I documented the source code using class level and method level comments and checked in the code to the svn repository. Last Thursday I attended the weekly Developer Call and listened to the final presentations of the Group-3 GSoC students. There were some good presentation on GSoC projects.

According to the GSoC 2010 timeline, next week is the deadline for the final evaluations. I had an awesome 12-weeks, working on the Flowsheet module and with the OpenMRS community. It is a life time opportunity for me to work with the developers all around the world. As I have reached all the goals we planned for the summer, I am so glad and feel very much satisfied. I hope everything will be fine with the final evaluations... The great motivation I got while working with the OpenMRS community during this summer opened me new paths towards contributing to FOSS. I am sure that this is a good starting point for me to reach many targets in contributing to the Open Source communities... I will continue my contribution to OpenMRS in the feature and will try to contribute to some other open source projects as well...

Eagerly waiting for the final evaluations next week...

Leveraging the new features in GXT (Ext GWT) 2.2 Beta...

I couldn't blog last week. So I will be writing about how I progressed with the enhancements to the flowsheet module in the past two weeks. I completed my final demonstration on July 22nd and it was very success. I received very good feedback and more motivation from the OpenMRS community. I was really happy to hear that the developers of the community liked the progress of the project and the new look to the module.

After the demonstration I started working on the feedback given by my mentors, Burke and other developers. One of the major issue I had earlier was the height of the main Grid widget. Earlier I had a fixed size for the height of the grid, an integer multiple of the number of rows in the grid. But in some browsers, there were more white spaces left in the bottom and in some other browsers there was scroll bar added to the grid. After trying with many options, finally I found the best way to do it following the AutoHeightGrid sample. Now the Grid's height is adjusted automatically.

Another feature suggested was to highlighted the selected obs value in the graph as well. I managed to do it my using a star for the selected value and dots for other values. The screenshot below shows the change:

I did the other small changes like header of the pop-ups, make windows to close when ESC is pressed, etc, as suggested. Thereafter I started working on the two tasks left in the development plan: Adding search functionality to search by a name of obs and handling abnormal flags.

I came across the new release of GXT and the features in Ext GWT 2.2 Beta. One of the major feature added is the functionality to filter grid columns using boolean, integer range, string values etc. I understood that this new feature will be handy in doing the first task I mentioned above and went through the sample widget using this feature. I managed to get the way to add the filtering feature and added it to the main grid of the flowsheet after upgrading the GXT jar to Ext GWT 2.2 Beta. The output was very nice! The filtering of column is very fast and easy to handle. Some screenshots below showing this new features:

I believe that this filtering feature will be very handy.

I added some code to show the abnormal values using a color code; this color code will be finalized with others' suggestions. I'll add data about the color code in the flowsheet once it's finalized, so that others can understand it easily. Since there are no much abnormal data, I couldn't check all the scenarios; I will be adding more data and checking them as well. Once such indication is shown in the screenshot below.

While reaching the end of summer in next two weeks, I am left with the documentation work now. I started on writing the module documentation and will be completing it by next week. Looking forward to complete all planned tasks before the 'pencils down' date of GSoC and then continue further enhancements with future versions.
