Detailed Description

An ellipse.

Ellipse example. Blue dotted circles are anchors, solid blue discs are positions.

It has two positions, topLeft and bottomRight, which define the rect the ellipse will be drawn in.

Constructor & Destructor Documentation

QCPItemEllipse::QCPItemEllipse ( QCustomPlot * parentPlot )

Creates an ellipse item and sets default values.

The constructed item can be added to the plot with QCustomPlot::addItem.

This function is used to decide whether a click hits an item or not.

pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the shortest pixel distance of this point to the item. If the item is either invisible or the distance couldn't be determined, -1.0 is returned. setSelectable has no influence on the return value of this function.

If the item is represented not by single lines but by an area like QCPItemRect or QCPItemText, a click inside the area returns a constant value greater zero (typically 99% of the selectionTolerance of the parent QCustomPlot). If the click lies outside the area, this function returns -1.0.

Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).

The actual setting of the selection state is not done by this function. This is handled by the parent QCustomPlot when the mouseReleaseEvent occurs.

void QCPItemEllipse::setBrush ( const QBrush & brush )

Sets the brush that will be used to fill the ellipse. To disable filling, set brush to Qt::NoBrush.

void QCPItemEllipse::setPen ( const QPen & pen )

Sets the pen that will be used to draw the line of the ellipse

See Also: setSelectedPen, setBrush

void QCPItemEllipse::setSelectedBrush ( const QBrush & brush )

Sets the brush that will be used to fill the ellipse when selected. To disable filling, set brush to Qt::NoBrush.

void QCPItemEllipse::setSelectedPen ( const QPen & pen )

Sets the pen that will be used to draw the line of the ellipse when selected
