Member Function Documentation

getObj()

Polygon & getObj ( )

inlinenoexcept

getLineIndexAtPosition()

int getLineIndexAtPosition ( const Point &  pos ) const

noexcept

Get the line segment at a specific position

Parameters

pos	The position to check for lines.

Returns

The index of the vertex after the line under the cursor. So for the first line segment, index 1 is returned. If no line is located under the specified position, -1 is returned.

Here is the call graph for this function:

getVertexIndicesAtPosition()

QVector< int > getVertexIndicesAtPosition ( const Point &  pos ) const

noexcept

Get the vertices at a specific position

Parameters

pos	The position to check for vertices.

Returns

All indices of the vertices at the specified position.

Here is the call graph for this function:

setEditable()

void setEditable ( bool  editable )

noexcept

Enable/disable editing mode when selected

If the item is editable and selected, vertex handles will be shown to indicate that they can be moved. If not editable, handles will not be shown.

Parameters

editable

Whether the polygon is (visually) editable or not.

itemChange()

QVariant itemChange ( GraphicsItemChange  change, const QVariant &  value  )

paint()

void paint ( QPainter *  painter, const QStyleOptionGraphicsItem *  option, QWidget *  widget = 0  )
