QPaintEvent error incomplete type

[ofmrew]

I get a compile error of incomplete type when compiling:

void MyFirstWidget::paintEvent(QPaintEvent * e)
{
QRect rw = this->rect();
QPainter painter(this);
QRect r = e->rect();

if (drawValue == 1)
    painter.drawLine(1 , 1, 1000, 1000);

}

Hi! You probably forgot #include <QPaintEvent>.

[ofmrew]

You are correct I forgot the #include <QPaintEvent> Thanks, that fixed it. My C++ is rusty.

@ofmrew How do I mark it as resolved?

There is the button "Topic Tools", and then: "Mark as solved". See https://forum.qt.io/topic/71830 for a short visual help.
