Getting Back on Track

Today we finally got an answer to our query on how to work with QGraphicsScene and QGraphicsItems.

We asked around on IRC and ML but didn’t get a reply. So we posted our query along with code of our demo application on Qt’s forum.

And at last somebody replied and pointed our mistake.

We were creating a scene directly in our mainwindow and each entity has its own mouse events associated with it like mousepress, mousemove, etc. and the paint event was also defined here.

But we have to handle events in the scene and not in the item. Only painting is to be done in item class. So now we have separate graphicsscene class which will handle the events.

Exploring Examples

Qt is marvy but it takes a plenty of time and investment to get fruitful results and better grasp on it.

Today Dr. Rai advised to go through the examples of Qt to have its overview.

Though there are loads of examples available, it’d be more fitting to go only through the selected ones that are related to our immediate work.


Today I got the access on the eCAD repository for GreatDevelopers account on github.

So I shifted the files from GDCAD repository to this eCAD repository.

Now any further work will be done on this new repository.

We also need to look into the source code of FreeCAD. Need to clone the code tomorrow.

Second task in LH

We finished our second task to implement AJAX in lab report form.

It was pretty easy after the first task and less complex ’cause it was a standalone form not on the admin side.

I feel as I am getting a little hang on Django.

Now I am going through the unit-tests in the LCv3 and looking into the code of kernel.

Finished with the task

Kamalpreet and I are finished with our first task of implementing the dependent drop-downs. After successfully implementing a form on a new page we had to do embed the same on admin side.
We had help from Jasvir as it was really tricky to get the drop-downs to work as we wanted to.

And now we got our second task to do similar AJAX thing in Lab Reports. This time we have to include a template as well.

On the note of my original project, GD-CAD, I am now cloning the LCv3 repo to study the kernel while following this motto:
I don’t have to reinvent the wheel, but I will be cautious before I act.

Almost done

Today we looked into how to add the fields in the admin side.

We had already created a form last time when we were trying to do in admin directly except the form should be a ModelForm instead of a simple form.

After searching online and help from Jasvir, we have the form added recursively (for multiple items).

Next I am looking into correcting the jQuery and AJAX implementation.

On the other note, I’ve passed my final evaluation in GSoC.
