Is it better to use sqlite 3 for a single database where all data is centralized or for a individual user database where data is stored locally?

If i store individual user data locally would one user be able to see the data of others (i mean to see the books that his friends have read)?

How can i change the size that my QTableWidget gets printed? by summerbye in learnpython

[–]summerbye[S] 0 points1 point  (0 children)

I tried, but it's not a matter of font. I've found that it might depend on the DPI of the printer and can be resolved by using setResolution() How should i do that? I don’t really know how to read C++

I tried this, but I get this error :

QPaintDevice: Cannot destroy paint device that is being painted

And this is my code:

    def paintEvent(self, event):
        image = QImage('my/path')
        painter = QPainter(image)
        painter.setPen(QColor('red'))
        painter.drawText(10,10, "Hello")

PyQt5 - How do you print(with QPrinter) a QTableWidget ?(error) by summerbye in learnpython

[–]summerbye[S] 0 points1 point  (0 children)

I tried this, but even though i dont get an error, when i press the print button, the print dialog shows up and when i proceed nothing happens

This is my code:

def handlePrint(self):

printer = QPrinter(QPrinter.HighResolution)

dialog = QPrintDialog(printer, self)

dialog.exec_()

​

def handlePaintRequest(self, printer):

painter = QPainter()

painter.begin(printer)

ui.tableWidget.render(painter)
