First time I was doing something to change in source code of a Program. I got something missing in "Filewatcher" widget. It was the Plasma ToolTip view which it should show when mouse is hovered over that particular widget. That time it was showing in traditional Qt style which is not recommended in Plasma.
So, Now I got a chance to do something in KDE. I know it was not a big thing for other developers but for a person who is doing first time anything in it, it's a big achievement for him. I started searching and understanding in other similar widget's source code where I found similar feature. Once, I also asked on IRC channel in "#kde-in" for some help.
Then, I came to know about "ToolTipManager". I tried it for two days and finally next day in morning , I got the result. It was really unexpected for me. I was so much happy after that. Then, I have to submit it on "reviewboard". I was totally new to that. My friend Shantanu who is already a very good KDE-Developer, he told me to ask on IRC channel as he was busy that time. I asked on IRC channel. Really, they are very helpful. I followed their instruction and finally, I was able to submit my first patch.
You can see it on http://reviewboard.kde.org/r/4730/. Then, I got comments from Aaron J. Seigo who is a great person.Further, It was committed by Shantanu. Special, thanks to him as he is the person who helped me lot in getting started.
