Confusion with QPoint

[therealjag]

here is the rest of the error message - hope this helps:

How did you declare that shapeItem variable?

[therealjag]

basically what i am wanting to do is display a number inside a circle which gets displayed at shapteItem.position(). my code for the displaying of the circes is like below:

QPainter painter(this);

foreach (ShapeItem shapeItem, shapeItems)
{
QPoint text(100,100);
QPoint mid(shapeItem.position())

painter.translate(shapeItem.position());
painter.setBrush(shapeItem.color());
painter.drawPath(shapeItem.path());
painter.translate(-shapeItem.position());
painter.setPen(initialItemColor());
painter.drawText(QRect(mid,text),0,tr("%1").arg(sh apeItem.instanceNumber()));

}

ShapeItem is a class in another fle named ShapeItem.cpp and the shapeItem.position was decared in the header file as :

void setPosition(const QPoint &position); and QPoint position() const; where the QPoint is a private variable. my function inside shapeItem is then as follows:

QPoint ShapeItem:osition() const
{
return myPosition;
}

and:

void ShapeItem::setPosition(const QPoint &position)
{
myPosition = position;
}

hope that helps, cheers

All looks OK here.

Is that the first error you get?

[therealjag]

i got it to work using the following code: QPoint mid(shapeItem.position()); but it doesnt display anything on the screen for some bizarre reason when i try to draw it with this:

painter.setPen(initialItemColor());
painter.drawText(QRect(mid,text),0,tr("%1").arg(sh apeItem.instanceNumber()));

i think its a lost hope cos i cant think of aything else to use???!!

What does this output?

painter.setPen( initialItemColor() );
QRect r(mid,text);
qWarning( "x=%d y=%d w=%d h=%d", r.x(), r.y(), r.width(), r.height() );
painter.drawText( r, QString::number( shapeItem.instanceNumber() ) );

painter.setPen( initialItemColor() );
QRect r(mid,text);
qWarning( "x=%d y=%d w=%d h=%d", r.x(), r.y(), r.width(), r.height() );
painter.drawText( r, QString::number( shapeItem.instanceNumber() ) );

To copy to clipboard, switch view to plain text mode

i managed to get it working. i was kinda simple in the end, maybe i wasnt explaining my problem properly. all i did was just change the parameters for the drawText function. to the following:

painter.drawText((shapeItem.position( )),tr("%1").arg(shapeItem.instanceNumber()));


thanks for your help - much appreciated. Jag
