Detailed Description

Constructor

Deconstructor

equal to (==) operator

copy ( = ) operator

Returns the size of the serialize class

Saves and loads the class information

Returns the point at the point index.

Sets the position of an already set point.

Checks, if we are at an end of the segment or somewhere in the middle. We use the delta, because with the mouse it is hard to find the exactly point.

Inserts a point at the given index.

Removes the point given by the index.

Sets the start and end points.

Returns the amount of POINTS on the line. Includes start and end points.

Returns -1 if the given point is not on the line. else returns the line segment the point is on. Use the value to insert points at the point position.

Sets the canvas to be used.

Sets the Association type.

Calls a group of methods to update the line. Used to save you calling multiple methods.

This will setup the class ready to display the line correctly. This MUST be called before you can use this class.

Returns the Association this class is linked to.

Sets the status of whether the line is selected or not.

Removes and item created that are no longer needed.

[protected]

Returns the canvas being used. Will return zero if the Association hasn't been set.

This class doesn't hold this information but is a wrapper method to stop calls to undefined variable like m_pAssociation.

[protected]

Returns the Association type. Returns Uml::at_Association if association hasn't been set.

This class doesn't hold this information but is a wrapper method to stop calls to undefined variable like m_pAssociation.

[protected]

Returns the Line Color to use. Returns black if association not set.

This class doesn't hold this information but is a wrapper method to stop calls to undefined variable like m_pAssociation.

[protected]

Moves the selected canvas widgets.

[protected]

Sets up the selected canvases needed.

[protected]

Returns the type of pen to use depending on the type of Association.

[protected]

Updates the head lines. Call after calculating the new points.

[protected]

Creates the line objects to display the parallel line.

[protected]

Calculates the position of the parallel line.

[protected]

Updates the parallel line. Call after calculating the new position.
