Description: A point class with double (floating-point) coordinates
Points represent a coordinate in the two-dimensional coordinate space of layout. They are not geometrical objects by itself. But they are frequently used in the database API for various purposes. Other than the integer variant (Point), points with floating-point coordinates can represent fractions of a database unit.
See The Database API for more details about the database objects.

!= | Signature: [const] bool != (const DPoint p) Description: Inequality test operator | ||

*= | Signature: DPoint *= (double f) Description: Scaling by some factor Scales object in place. All coordinates are multiplied with the given factor and if necessary rounded. | ||
+ | Signature: [const] DPoint + (const DVector v) Description: Adds a vector to a point Adds vector v to self by adding the coordinates. Starting with version 0.25, this method expects a vector argument. | ||
- | (1) Signature: [const] DVector - (const DPoint p) Description: Subtract one point from another Subtract point p from self by subtracting the coordinates. This renders a vector. Starting with version 0.25, this method renders a vector. | ||
(2) Signature: [const] DPoint - (const DVector v) Description: Subtract one vector from a point Subtract vector v from from self by subtracting the coordinates. This renders a point. This method has been added in version 0.27. | |||
-@ | Signature: [const] DPoint -@ Description: Compute the negative of a point Returns a new point with -x, -y. This method has been added in version 0.23. | ||
/ | Signature: [const] DPoint / (double d) Description: Division by some divisor Returns the scaled object. All coordinates are divided with the given divisor and if necessary rounded. | ||
/= | Signature: DPoint /= (double d) Description: Division by some divisor Divides the object in place. All coordinates are divided with the given divisor and if necessary rounded. | ||
< | Signature: [const] bool < (const DPoint p) Description: "less" comparison operator This operator is provided to establish a sorting order | ||
== | Signature: [const] bool == (const DPoint p) Description: Equality test operator | ||
_const_cast | Signature: [const] DPoint ptr _const_cast Description: Returns a non-const reference to self. Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects. This method has been introduced in version 0.29.6. | ||
_create | Signature: void _create Description: Ensures the C++ object is created Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. | ||
_destroy | Signature: void _destroy Description: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | ||
_destroyed? | Signature: [const] bool _destroyed? Description: Returns a value indicating whether the object was already destroyed This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | ||
_is_const_object? | Signature: [const] bool _is_const_object? Description: Returns a value indicating whether the reference is a const reference This method returns true, if self is a const reference. In that case, only const methods may be called on self. | ||
_manage | Signature: void _manage Description: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. | ||
_unmanage | Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. | ||
abs | Signature: [const] double abs Description: The absolute value of the point (Euclidian distance to 0,0) The returned value is 'sqrt(x*x+y*y)'. This method has been introduced in version 0.23. | ||
assign | Signature: void assign (const DPoint other) Description: Assigns another object to self | ||
create | Signature: void create Description: Ensures the C++ object is created Use of this method is deprecated. Use _create instead Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. | ||
destroy | Signature: void destroy Description: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | ||
destroyed? | Signature: [const] bool destroyed? Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | ||
