It is also worth noting that all PyQt widgets have Tooltips: helpful phrases that can explain what a widget is for. In fact, since the listbox automatically includes a slider, you will find it a bit easier. If you want to build a GUI using listboxes, buttons and checkboxes, you won’t have any trouble with PyQt. He has also written a book on PyQt and there is a link to it at the bottom of the tutorial.

I learned how to use PyQt5 from the on-line PyQT5 reference guide as well as from this short tutorial by Michael Herrman. It allows you to select any person in our database and assign them a role in the current or an older production. The left-hand table is the final cast, sorted by role-type and sex, which amounts to one simple database query. This screen represents a way to create a cast list for the current and previous shows and generate spreadsheets of those casts for the Board, the cast and the directors to work with. I built the Tkinter version of this interface as part of a larger development project to interface our opera company’s data to a new MySQL database, where building a UI gave us the ability to view the information in more flexible ways. There was no clear winner of this experiment: once you have climbed the learning curve you can build nice-looking systems either way. The rest are just hardcoded,īut basically, the systems do about the same things and are about equally easy (or hard) to use, and you can’t go wrong using either of them. The tkinter version is fully integrated with the database, but I only bother to connect the right hand searchbox and listbox to the database in PyQt5. Each system has different advantages and disadvantages, and we’ll summarize them in the article that follows. I spent a week learning PyQt5 and building the new interface to match the one I had already built in Tkinter.

They show that you can build pretty much the same kind of GUI with either system. My_w.The two figures above show the same interface developed in Tkinter and PyQt5. R_set=my_conn.execute('''SELECT * from student LIMIT 0,10''')

Once the connection object my_conn is created then the code remain same in case of SQLAlchemy. We used variable i as index for each row and variable j as each column of data. In this variable student is a tuple and it contains one row of data. We will use one tkinter entry component to display each data in the window. This will print 10 rows of records from student table. So we used another for loop to display each element of this tuple. Each row of data ( here student ) is a tuple. We will use one for loop to collect each row of record from the data set. We used the returned record set i.e r_set as an iterator. This result set contains all our (10) records. Note that SQLite database executes the query part only and return us one result set.

You can change this figure to get different number of records from the database. We will use Query with LIMIT to collect 10 records from the student table.īy using LIMIT Query we are restricting our number of records by getting 10 records only from SQLite database.

We will use my_conn in our further script as the connection object to get our records.ĭownload or Create my_db.db SQLite Database » The commented line is used when we keep SQLite database in Google Drive.

In windows system, the absolute path is used in above code. #my_conn=create_engine('sqlite:////content/drive/MyDrive/db/my_db.db') My_conn = nnect('my_db.db') using SQLAlchemy connection from sqlalchemy import create_engine We connected to sqlite database and create our student table with sample data.
