Problem with window-viewport coordinate

[damon_1990]

Thanks for answer. So, I change my code:

void Diagram::mousePressEvent(QMouseEvent *event)
{
	     QPoint point = event->pos();
 
       QPainter painter(&pixmap);
       painter.setWindow(-50, -50, 100, 100);
 
			 QPoint out = painter.transform().inverted().map(event->pos());
 
       qDebug() << point.x() << point.y();
       qDebug() << out.x() << out.y();
}

void Diagram::mousePressEvent(QMouseEvent *event)
{
	     QPoint point = event->pos();

       QPainter painter(&pixmap);
       painter.setWindow(-50, -50, 100, 100);

			 QPoint out = painter.transform().inverted().map(event->pos());

       qDebug() << point.x() << point.y();
       qDebug() << out.x() << out.y();
}

To copy to clipboard, switch view to plain text mode 

but I still get the same value, for example:

188 158 
188 158

188 158 
188 158

To copy to clipboard, switch view to plain text mode 

and I can't check this condition

up_p.containsPoint(out, Qt::OddEvenFill)

up_p.containsPoint(out, Qt::OddEvenFill)

To copy to clipboard, switch view to plain text mode 

because I have polygons defiened like:

static const int upPoints_p[4][2] = {
        { 49, -49 }, { -49, -49 },
        { -10, -10 }, { 10, -10 }
 };

static const int upPoints_p[4][2] = {
        { 49, -49 }, { -49, -49 },
        { -10, -10 }, { 10, -10 }
 };

To copy to clipboard, switch view to plain text mode 

So, what am I doing wrong?
