Drag and drop issue in Qt - qt

Question

I overload dragEnterEvent() and dropEvent() in my MainWindow class, and call setAcceptDrops() in the constructor. While the running, I drag a .txt file in to the texteditor, but it's not showing the content of that .txt. Instead, it's show the path of that .txt. Please somebody help where I did wrong. Thanks.

You see this behavior because dropping is enabled on QTextEdit and the event is consumed there. (By default TextEdit drop copies filename into text area.)
In your constructor disable dropping on TextEdit by using
ui->textEdit->setAcceptDrops(false)
and then the event will be handled by the dropEvent method in MainWindow
