TUTORIAL - Circular Progress Bar - Qt Widgets (CUSTOM WIDGETS / Python / PySide6) PART 1

//// DOWNLOAD SOURCE CODE ////

//// PART 2 ////

In this tutorial I will teach you how to create custom widgets, these widgets can be reused just like we do with Qt Quick using QML files, with the difference that we can do all of this directly within Python.

This video is part of a video related to PyDracula, however you can reuse this custom widget in any project you want as I will teach in the second video, creating a Splash Screen for the PyDracula Project.

Good studies to all.

very good. If your graph is not show, here are some observations.
1. the variables self.width and self.height cannot be declared since QWidgets has methods with that name. By the way, you don't even need them, you can get this value self.width() self.height()

2. you cannot call self.size(200, 200) to set the window size, user self.setFixedSize(200, 200)
or self.setMinimumSize(200, 200) self.setSizePolicy(QSizePolicy.Fixed, QSizePolicy.Fixed)

3. It is not necessary to create a rect to center the text, you can get the rect from Qwidgets using self.rect()
4. you probably need to call self.repaint() after updating value

@Wanderson What VSCode color theme are you using? I also wonder what addons have you installed for VSCode and recommending the most, for Python.

[ekitran]

it gives an error when I use the loop. how to fix it?
QPainter::begin: A paint device can only be painted by one painter at a time.
QPainter::setCompositionMode: Painter not active
QBackingStore::endPaint() called with active painter; did you forget to destroy it or call QPainter::end() on it?

What is the use of the following code (at 6:00) in the circular_progress.py file:

paint.setPen(Qt.NoPen)
paint.drawRect(rect)

I do not see it being used in the remainder of the code, and when I comment out the lines it does not seem to make a difference.

Can you introduce some useful books in similar fields?
