Question

I am developing an app in which I am using QTableWidgets, and I need to set their background transparent, I have tried to setStyleSheet "background:transparent;", but nothing happened.

Is there any other way to do it?

You’re on the right track. Try:

setStyleSheet("QTableWidget {background-color: transparent;}"
              "QHeaderView::section {background-color: transparent;}"
              "QHeaderView {background-color: transparent;}"
              "QTableCornerButton::section {background-color: transparent;}");
QTableWidget *table = new QTableWidget(latticeView);
table->setRowCount(2);
table->setColumnCount(2);

Note that I’m setting the style sheet before creating the table widget. I don’t know why, but that seems to be necessary.
