You don’t need to label it, as we will print the output in here. But before that, we change the name of the button (and not the text) to calc_tax_button.ĭrag another Text Edit box on to the window. By now, you should know how to change this. The button just says PushButton, which isn’t very helpful. Now, select the Push Button box and drag it to our window. Also look at the circled Push Button we will be using next: We will also add another label called Tax Rate, same as we did before. If you look at the image above, you can also set the minimum and maximum limits. We can choose a default value for our spinbox. Remember, this is how this object will be called from Python. The first thing we do is change the objectName to something sensible, tax_rate in our case. We don’t need a spinbox, it’s just good to see how you can use different widgets that QT Creator provides. You can also make the text large and bold, as seen here:įor the tax box, we are going to use something different. The next thing we will do is attach a label to the box, to make it clear to the user what this box is for.Ībove, I have circled the label.
I’m calling it price_box, as we will enter the price into this box. The name is the way this object will be called from our Python code, so call it something sensible. See the right side, where I have red circled a box? That is where the name of the object is. The next thing to do is to select the Text Edit box on the left:ĭrag Text Edit to the main window, to get a box like: In the window that comes up, choose Main Window, as it will give is a blank canvas: If not, you will need to get it from:, then install pyqt5 with: pip install pyqt5
The easiest way to start is to download Anaconda, as it comes with Qt designer and PyQT inbuilt (in …\Anaconda3\Library\bin, qtdesigner.exe). So no struggling laying out the design by hand. We will be using the superb QT Designer tool to layout our app: Most tutorials on GUI apps try to layout the GUI blocks using code, but that is very painful to do. Once you understand the basics, it’s easy to add advanced stuff.Ī simple GUI app that takes in a price, a tax rate and calculates the final price.
We will get around that by building a simple GUI app, and show you how easy it is to get started. Most tutorials are purely text based, and it’s hard to learn GUI development using text, since GUIs are mainly a visual medium. The most common reason is, they don’t even know where to start. Many people struggle with learning how to build a GUI app.
