Public Instance Constructors

Entity Constructor Empty constructor.

Public Instance Fields

Catchenabled If Catchenabled is false, you cannot hit the entity, otherwise it is a candidate to catch them with the mousepointer. Default is true; Select
Children (inherited from MNComponent)
GenerateNames (inherited from MNComponent) If GenerateNames is true, a Name will be generated, if the parent is set to a component which has no name. With GenerateNames is guaranteed, that every member of a tree (except the root) has a unique name and there is a fullpath, with which the element can be identified.
UpDateCount (inherited from MNComponent) Sets or gets a counter. It will be incremented by the method UpDating and deremented by UpDated. If it is 0 then UpDate is called.

Public Instance Properties

Base Base is an other aspect of Transformation. She is given from Transformation by the conversion with toBase For some it is easier to work with a base as with a transformation. It is also easier to imagine it as a base. All coordinates, used in the drawmethod of the entity are taken relative to this base.
Count (inherited from MNComponent) Returns the count of children
Global Get a transformation to global coordinates. The transformation of all ancestors of an entity will be multiplyed and returned.
Item (inherited from MNComponent) The default indexer retrieves and sets MNComponents
Name (inherited from MNComponent) Name of the component.
PaintChildren If PaintChildren is true, all children will be drawn. The default value is true.
Parent (inherited from MNComponent) Sets or gets the parent of the component and looks for the correct and unique name.
See also GenerateNames, setParent
Tag (inherited from MNComponent) A free programmable property, which is not stored in a file.
Transformation Every Entity has a transformation which is called in the Paint-method. This transformation is also valid for a child and a child's child and so on.
Visible If Visible = true the the entity will be drawn. Default is true

Public Instance Methods

Add Adds a Entity E as child.
addChild (inherited from MNComponent) Adds an elment in the list.
checkuniquename (inherited from MNComponent) If the parent is setted, this method returns a name, consisting of value and a number, so that it is unique in his parent.
ChildByName (inherited from MNComponent) Retrieves the index of child by a name.
ChildByPathName (inherited from MNComponent) You can get a MNComponent by setting a fullpath relative to the given MNComponent. The names are seperated by "/".
MNComponent root = new MNComponent();
MNComponent a = new MNComponent();
MNComponent b = new MNComponent();
MNComponent c = new MNComponent();
a.Name = "Frank";
b.Name = "Joe";
c.Name = "Sam";
c.Parent = b;
b.Parent = a;
a.Parent = root;
MNComponent d = root.ChildByPathName("Frank/Joe/Sam");
// d is then the component c

Equals (inherited from Object) 
fullPath (inherited from MNComponent) Gives the full path of the component over all ancestors until a null-parent occurs. This parent is often called the root. To separate the names "/" is used.
GetEnumerator (inherited from MNComponent) Returns the Enumerator of an intern ArrayList
GetHashCode (inherited from Object) 
getName (inherited from MNComponent) Returns the name
getPath (inherited from MNComponent) Returns a path, whose member are separated by "/" beginning with "/"
getRoot (inherited from MNComponent) Implements the ISerializePath interface. If parent is null then it returns the object itself.
GetType (inherited from Object) 
InsertChild (inherited from MNComponent) Insert a MNComponentobject at position index.
MoveTO (inherited from MNComponent) Moves a children-component to a position
Paint This method is called by Paint. She sets the Transformation
RemoveChild (inherited from MNComponent) Removes a component.
ToString (inherited from Object) 
Transform Implements ITransform: the transformation will be multiplied by the Matrix T.
UpDate Overrides the UpDate- method and informs the MNDevice, that the contents have changed.
UpDated Overrides the UpDated-method and informs all devices in which the entity is visible. So a change of an entity arouses changings in all devices.
UpDating Overrides the UpDating-method and informs all devices in which the entity will be drawn by a call of their Updating-method.

Public Instance Events

OnDisposed (inherited from MNComponent)
OnDraw From draw a OnDraw-event is fired. You can use them. So you don`t have to derive a component.
OnPaint Event called by Paint
OnUpdate (inherited from MNComponent) This event is called by UpDate
OnUpdating (inherited from MNComponent) This event is called by UpDating

Protected Instance Methods

Disposed (inherited from MNComponent) Setzt den Parent auf null.
draw From the Paint-method a 'draw' is called. It is better to override drawmetod than the Paintmethod, because in the Paintmethod some calls enclose the drawmethod ( for example the transformation will be setted ).
Finalize (inherited from Object) 
GetTransformation GetMethod of the property Transformation
MemberwiseClone (inherited from Object) 
setParent Overrides the setParentmethod, because in that case the visibility has changed.
SetTransformation Setmethod of the property Transformation
SetVisible Virtual setmethod of the Visible-property.
