'can't change backgrund border of qtextedit in Pyqt5, any suggestions?
I could not change the background shape of the text. Is it possible or should i try another way to get it solved. Thanks. This what i have so far. I tried to add broder-radius to html in qtextedit but whenever i tried QtCreator did not accept what i have done and reset the code to the current html i shared now.
font = QtGui.QFont()
font.setFamily("MS Shell Dlg 2")
font.setPointSize(8)
font.setStrikeOut(False)
self.ui.textEdit.setTextBackgroundColor(QtGui.QColor(143,188,143))
self.ui.textEdit.setAlignment(QtCore.Qt.AlignRight)
self.ui.textEdit.append("Here is the background i want to change. Iwant it to be round instead of a corner.")
self.ui.textEdit.setLineWrapMode(self.ui.textEdit_2.LineWrapMode(3))
self.ui.textEdit.setLineWrapColumnOrWidth(40)
self.ui.textEdit.setWordWrapMode(1)
self.ui.textEdit.append("")
self.ui.textEdit.setFont(font)
self.textEdit_2.setHtml(_translate("MainWindow", "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \"http://www.w3.org/TR/REC-html40/strict.dtd\">\n"
"<html><head><meta name=\"qrichtext\" content=\"1\" /><style type=\"text/css\">\n"

Here is the whole Code which i tried to run. It is not showing the plain text for any reason and gives me folliwing fault:

QPainter::setBrush: Painter not active

Solution 1:[1]
Update2
Sorry, I mistook... you have given me the complete code , I've never been aware of it.In this case , even if I use installEventFilter, the contents of paint is overdrawn by your setStyleSheet settings , and so on.
So I have discovered I can make a subclass of QTextEdit, I did it. Please try my code again.
Okay, I saw your update, I think you don't understand the system of eventFilter enough.Event streams from parent to child.(in this case, easily to say , (QObject)?QApplication?QMainWindow?QTextEdit)
Normally, event is overridden in the subclass of the class directly.
Because you want to draw the viewport of QTextEdit, you must override the paintEvent in the subclass of QTextEdit.But in this case, you made GUI by Qt-Designer.
You cannot write the code for overriding paintEvent in QTextEdit.
The major way is to get the same effect for overriding paintEvent, for this, you can install eventFilter.At the time of QMainWindow, you can change the stream of event.Here, now, I changed the stream only in the case of self.ui.textEdit by
If obj is self.ui.textEdit flag.

OLD
please try this code.
you managed to draw rounded rect background.
But the range I can control now is as follows:
- the backgroundcolor is adopted to texts all around.
- the color is the same.
If you change something, you must probably think about coding every time.
pls dock the code to yours.
Note:
line.rect() returns a relative rect of QTextLine. The topLeft is (0, 0).
If we use this rect as it is, we cannot draw appropriate rect from the 2nd block.
So I also got blockBoundingRect and translated lineRect.This rect contains documentMargin.
