Qt for Python

@Harning Hello and welcome. Your question is unclear: what does "diffrent with table header" mean? If you have a model, and you are using, say, a QTableView to display it, one way is to use QVariant QAbstractItemModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const where for role == Qt::ForegroundRole or perhaps Qt::BackgroundRole you make it return the desired color. If the color varies by row number you can look at the passed in index.row() to determine which color to return.

@Junhi, if __name__ == "__main__": prevents invocation as module, instead only as script.

@LorDawid QPixmap::fill() is probably an "expensive" operation (pixmap could be "large"), and also a waste if you then do your own fill or set your own pixmap, so that is presumably why they leave it uninitialized.

PLease use the current version 6.5; PySide2 does not support this. See https://doc.qt.io/qtforpython-6/gettingstarted/index.html .

@FaTr You do not set any items in column 0 as far as I can see (so item(r, 0) returns None), that is why you get this error.

@pascor When I did Python-Qt stuff a few years ago I used PyCharm as my IDE. Which I found very good. Certainly if you did elect to use the pyuic/pyside6-uic route of processing the .ui file to produce a source file --- which the C++ build has to do --- rather than the run-time QUiLoader::load() you got invaluable development-time support like auto-completion of member variables etc. etc. It is true that the hassle of having to run pyuic each time after changing the .ui file was a minor irritant, but worth it for the other benefits one gained. I don't know what the editing/debugging experience for PySide inside Qt Creator is these days, but probably poor? There was no support at all in my time. Does it have an integrated Python debugger with your source code when you run? If not I would use PyCharm.

@Nergui Not sure what help you are expecting. You have to draw a gyroscope and you have to connect to the sensor inn code through whatever API it offers.

I understood that you have to style the output, hence my answer. It's not the printer that does that part, it's the word processing application. A printer receives a set of instructions on how to print things, you can alter the color, the number of page per sheet and that kind of stuff in the printer settings. However, you cannot tell your printer that it has to use an interline space of 5. What you are currently asking for refers to what is called rich text. Hence my suggestions about loading your text file in a QTextDocument and then apply the styling you need, and then print that document.

Hi, So you would need something like a QSplitter but with two widgets on top of each other rather than beside ?

RESOLVED: In order to compose the desired stack image I needed to use a QPainter. My logic was roughly: baseImage = QtGui.QImage("<path to base image>") stackSize = 3 stackImageSize = QtCore.QSize(baseImage.width(), baseImage.height() * stackSize) stack = QtGui.QImage(size, QtGui.QImage.Format.Format_ARGB32) stack.fill(QtGui.QColor(0, 0, 0, 0)) painter = QtGui.QPainter() painter.begin(stack) for i in range(count): adjust = baseImageHeight * i + baseImageHeight - 6 * i painter.drawImage(0, size.height() - adjust, unselected) painter.end() label = QtWidgets.QLabel() label.setFixedHeight(size.height()) label.setFixedWidth(size.width()) label.setPixmap(QtGui.QPixmap.fromImage(stack)) layout = QtWidgets.QVBoxLayout() layout.addWidget(label) self.setLayout(layout)

If memory serves well, you can use the buttonSymbols property for that.

I found the solution by setting the widget resizeble by using scroll_1.setWidgetResizable(True)

@friedemannkleint Yes! Thank you! That allowed me to see that it was the "text/uri-list" data it was inserting. I ended up re-defining the Drop function for the QLineEdit class and that seemed to have done the trick! class FileDropLineEdit(QLineEdit): def __init__(self, parent=None): super().__init__(parent) def dropEvent(self, event): if event.mimeData().hasUrls(): file_path = event.mimeData().urls()[0].toLocalFile() file_path = file_path.replace("/", "\\") self.setText(file_path) event.acceptProposedAction() else: event.ignore() Since it's now its own class, I also removed the reference to the Drop event in my event filter and referenced it when creating the initial window.

The bug disappeared after qt upgrade to the version 5.15.9

@friedemannkleint I tried all that, I tried different versions of virtual environments. Finally I switched over to PyQt6 and now it works flawlessly.
