Google code in 2013 is on !



After my last summer's work in plasma ,here I am  mentoring Google code in 2013 .My tasks will be more of related to plasma though . And,I woud be glad to have a few suggestions and new ideas too! So if you are under 17 make sure to apply and contribute to KDE !
For now,I have three tasks that are related to QML,cmake and a brief knowledge of Qt would be great too .Documentation is always welcomed ! As I not only wish to have a working code but an optimised code ,so one of the tasks involves optimising a part of gsoc's work -window list which will involve making sure it follows white space indentation and the code is optimised . Other tasks too ,requires the basic knowledge of QML and cmake .And yes,students can always mail me or comment here for further queries ! 
Good luck to all the kids !

My Projects (2011-2015): Adios Gsoc 2013 ! :-) : A brief journey

My Projects (2011-2015): Adios Gsoc 2013 ! :-) : A brief journey: I worked on porting plasmoids to plasma1 and then to plasma 2 this summer under the guidance of  +Marco Martin  (KDE). During the initial ...

Adios Gsoc 2013 ! :-) : A brief journey

I worked on porting plasmoids to plasma1 and then to plasma 2 this summer under the guidance of +Marco Martin (KDE).
During the initial weeks I worked on trashcan (plasma 1) .
It was a pretty easy one to port so it was done in a few weeks .
After porting trashcan , I successfully ported window list in plasma 1 .Porting it was fine once you are clear with the concepts of data engines and QML of course !
 So , by nearly two weeks before the mid evaluation my expected mid evaluation work was almost done . 
Then came Akademy 2013 , that I would have attended , had I got my passport ready on time .But no worries I will surely attend Akademy 2014 :) . 
During the duration of Akademy 2013 I started porting digital clock , did a few hacks and it was working out .
But it ofcourse needed improvement :p
I spent most of my final evaluation time porting digital clock (plasma 1) .It is almost done , though it needs to use KCalendarSystem and  KHolidays is not yet implemented due to shortage of time .Otherwise , it is fine .
Then comes porting of plasma 2 and well building plasma-shell successfully is one of the most crucial task ! .
I was able to do that fortunately , so I first of all ported window list in plasma 2 and also added cascade and unclutter actions in data engines .After a bit of fixing layout problems in QML 2.0 it looks fine now . 
I made a simpler calendar component that works fine with digital clock I ported in plasma 2 . 
I had to make another calendar component as akonadi is not yet ported under kf5 .
But , the basic component still has the "working" functionalities for the calendar .
Then finally comes trashcan :p , though it was a simple one , kio trash was not yet ported at that time so it took some time .Thanks to +Marco Martin for contributing to kio trash as my exams were going on at that time (Yes !I  hate exams :p )
 Finally I fixed the layout of trashcan in plasma 2 and it is fine now . 
Last but most important of all , I also improved the documentation of KDE :)

Plasma 2 plasmoids this summer



      
  Window list plasmoid 










The main thing to be taken care of in this plasmoid is "data engine" .


I used tasksSouce in window list .And also to highlight the selected menu item I 





used PlasmaCore.FrameSvgItem .The text displaying the menu items become italics in case that window is minimised .

Further I have made it a PopUpApplet .

It shows the list of active windows on full view and collapses to icon on desktop panel .So,I managed to do it . 

I made new service for these actions since they require an empty source . Ofcourse ,these actions can be done by a source(by using the Ids on connectSources() also but then there is always a case when there is no window that is active at the moment) .

Therefore , empty source is required.Further , I added cascade and unclutter actions in tasks data engine by using asynch call to kwin interface using QDBusInterface .

 Also , the active window is enclosed withing PlasmaComponents.Highlight just like Actions and Desktop titles while highlight is shown by FrameSvg .






                               
     Digital Clock   




I made a basic component independent of akonadi,kdepimlibs and kdepim-runtime for now as kdepim-runtime is not yet ported to kf5 .It works fine with all the functionalities using a plugin calendar used for this purpose . 




The screenshot is self explanatory .

The bottom row toolbar shows current week and day by default with the calendar icon pointing to the current month.
 The upper toolbar helps to go to next month , previous month , next year , previous year and shows a context menu on clicking the month .
The current day is shown by a blue border .
On entering mouse event is shown by light grey color and on clicked mouse event is shown by black border .




TrashCan



This was pretty simple after I tried out calendar and window list .
But the kio trash was not yet ported fully so with the help of +Marco Martin it is working now .
It displays query dialog too just like the plasma1 plasmoid I made and the original trashcan . :)

That was a summary of my final evaluation work , and yes a digital clock in plasma 1 is too ported as in my previous blog .
I hope you will try it out !
Cheers !

Clock with calendar : Gsoc update

Well , I have been working on clock with calendar right after I ported window list and trash can .

And yes , it is "beast" of all the plasmoids .

I managed to implement one ,yes,  a basic one for now .It shows the events of the clicked date's month and those events that touches it .Further , it shows "No events founds" when the clicked date does not conatins any events .I also implemented containsTodoItems apart from other functionalities :) under +Mark Gaiser  and +Marco Martin  guidance  .

At present +Mark Gaiser  's calendar component is  used for it .The current date is shown under the blue border as in c++ plasmoid .

It is a way alike now ;) .

Also I used split function to have only a substring (event,todo or journal ) in EventList from the called string .I used ScrollArea for the EventList .

And I did a few javascript functions to implement the functionalities as well as a few functions in calendar.cpp itself .

It looks a much better after +Marco Martin suggested to have some indentation and follow white space coding .It presently uses QDate as for now .

The toolbar shows current date and week number by default .

There are two models used : setSelectedDay model : which shows the clicked date's events,todo or journal and upcomingDays model : which shows the upcoming events in case no events ,todo or journal is found .


Do check it out ;)


It is available at heenamahour/gsoc branch under kde-workspace and kdepim-runtime


That is all for now :)

And yes , window-list and trashcan are ported to plasma 2 (work is in progress ;) in parallel with calendar plasmoid :D ..)

Window list QML : Update



Recently I tried to make window list using qml(kde-workspace/  branch : "heenamahour/gsoc")



The main thing to be taken care of in this plasmoid is "data engine" .I used tasksSource in window list .And also to highlight the selected menu item I used 
PlasmaCore.FrameSvgItem .The text displaying the menu items become italics in case that window is minimised .






Further I have made it a PopUpApplet .It shows the list of active windows on full view and collapses to icon on desktop panel . 



Further , I added cascade and unclutter actions in tasks data engine by using asynch call to kwin interface using QDBusInterface .This required more time since I was new to it ,but my mentor is awesome .



So,I managed to do it . I made new service for these actions since they require an empty source . Ofcourse ,these actions can be done by a source(by using the Ids on connectSources() also but then there is always a case when there is no window that is active at the moment) .Therefore , empty source is required.







Now , I have also used sections as suggested by my great mentor +Marco Martin and under his guidance it also displays windows under their respective desktop . If section > 0 then it displays Desktop + Desktop number else it displays on all desktop as in C++ plasmoid .



Also , the active window is enclosed withing PlasmaComponents.Highlight just like Actions and Desktop titles while highlight is shown by FrameSvg .












That's all for now .Hope you like it !

Trashcan : Development Phase

                                                           Trashcan (QML)

Recently I developed trashcan which is available at kde-workspace ,branch:heenamahour/gsoc .
(not yet merged yet).

I have implemented a pop up menu having open and empty option .Just like the c++ plasmoid it can also be opened by left click on it .To confirm to empty the trash can on  using Empty Trash from the pop   up  menu  ,I have used a  QueryDialog.


It also displays the total number of items in trash using DirModel(plasma-mobile).It is resizable .Also ,I have added form factor  in it.
On Trash can  settings , config plugin is added using X-Plasma-ConfigPlugins .I have removed the background  by set.background hints(0).

I hope you will check it out ! :)

window-list using QML 1




 I tried to implement window-list using qml .Major functionalities are added to it using PlasmaCore ,plasma.graphicswidgets,plasma.graphicslayouts and qtextracomponents .
It involves quite a lot of javascript and qml to give a flexible ui .
Feels good to see it as it is my first plasmoid in qml . 
Looks similar ,isnt it :P

Zig Zag motion

On clicking the start button
Changed the ball's color to hgb

Using stop button






Using java swings ,I tried to make the zig zag motion  of a ball when it strikes the boundaries of the rectangle on clicking the "start" button It has a "stop" button and another button to change the ball's color to HGB.
The code is quite simple .First of all create a frame using JFrame as follow
JFrame a = new JFrame("Zig Zag");
After declaring its attributes ,create a class  say zigzag which inherits JPanel and another class say bounce which inherits JPanel and an interface ActionListener.Now declare an object of class bounce say bounce b;
After that declare the constructor zigzag() as follow
Before clicking the start button
b = new bounce();
JButton startButton = new JButton("Start");
JButton hgbButton = new JButton("Change color to HGB");
JButton stopButton = new JButton("Stop");
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new BoxLayout(buttonPanel, BoxLayout.X_AXIS));
buttonPanel.add(startButton);
buttonPanel.add(hgbButton);
buttonPanel.add(stopButton);
 stopButton.setText("Stop now !");
this.setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
this.add(buttonPanel);

this.add(b);
Now,for the start button set animation to true and for stop button set animation to false .To change the color to hgb use :
b.setBallColor(Color.getHSBColor(TOP_ALIGNMENT, TOP_ALIGNMENT, TOP_ALIGNMENT));
 Now,inside the class bounce define the radius,diameter ,velocity across Xaxis and Yaxis , paint()..
