The example below, which I’ve modified from the answer in Pyqt5 widget in grid expansion, starts like this:

In the example below, which produces this GUI:

The documentation https://doc.qt.io/qt-5/qt.html#KeyboardModifier-enum notes:

I am highlighting QGraphicsRectItem on the QGraphicsScene those objects have their unique name.

I’m making a GUI using PyQt5 where I have hexagonal cells that have a button that is part of a circle at some vertex. However, I can’t find a way to make the clickable area of the button be the arc, and nothing but the arc. Even when I create a “slice” widget and paint it, there is either a clickable area outside of the slice (making a clickable area of a rectangle), or the clickable area is too small. How can I make a button of the correct shape?
Here is a stripped-down version of my code. The button position is determined by the channel_pos argument for the Hex class; 0 is the top vertex and they are numbered clockwise around the hexagon.

I’ve added some keyboard shortcuts to my app (PyQt5), like so:

Code below populate a treewidget. TO change the design of the rows in treewidget, we add CSS like codes to stylesheet of the treewidget like below:

My code creates a composite widget, it is made of a button and a label.
It is part of broader code where this composite widget is the element of a list.
But now let’s focus on my problem that is:
How do I get to know the text in QPushButton at runtime?
This is the code:

I have a QListWidget, which contains many items (in the code named myList).
Each item has a QListWidgetItem which contains a QPushButton and a QLabel.

Using the example code below, I get four QLineEdit text fields/boxes, that stretch when I resize the main window horizontally, which I like:
