DrawCtrl overview

Public Instance Constructors

DrawCtrl Constructor Initializes a new instance of the DrawCtrl class.

Public Instance Fields

Catchenabled (inherited from Entity) 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.
HoverColor Holds the color in which a draw element will be drawn, if the cursor passes it.
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 (inherited from Entity) 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.
Color Color in which the ActiveCtrl will be drawed.
Count (inherited from MNComponent) Returns the count of children
CurrentHit Gets the CurrentHit from the HitItemlist. It is null, if the Hititemlist is empty or the first entry doesn`t belong to the DrawCtrl.
Device The ActiveCtrl belongs to that device +in case, that one ancestor is the field Work. If you set this property, the ActiveCtrl will be added to the children of Work.
Global (inherited from Entity) 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 (inherited from Entity) If PaintChildren is true, all children will be drawn. The default value is true.
ParentOverloaded.
PenStyleGets or sets the style of then pen, which is used in painting.
PenWidth Gets or sets the width of then pen, which is used in painting.
Tag (inherited from MNComponent) A free programmable property, which is not stored in a file.
Transformation (inherited from Entity) 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 (inherited from Entity) If Visible = true the the entity will be drawn. Default is true

Public Instance Methods

activateColor Activates a color in the device, depending on the PolygonMode. If PolygonMode has the value Fill, the ambient part of Material will be set. Otherwise PenColor
Add (inherited from Entity) 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

ctrlCircleOverloaded. Draws a controlled circle.
ctrlCurve Draws an active Curve C, which will be highlighted by the HoverColor if the mouse moves over it. With the parameter Tag you can set informations to identify the curve in an other context.
CtrlDisplaylist Draws a controlled display list
ctrlLineOverloaded. Draws an active line from A to B, which will be highlighted by the HoverColor if the coursor crosses it. With the parameter Tag you can set informations to identify the line in an other context.
ctrlMarkerOverloaded. Draws an active marker, which will be highlighted by the HoverColor if the mousepcursor passes it. With the parameter Tag you can set informations to identify the marker in an other context.
ctrlPolyOverloaded. Draws an active polygon a, which will be highlighted by the HoverColor if the cursor moves over it. With the parameter Tag you can set informations to identify the polygon in an other context.
CtrlRectOverloaded. Draws a rectangle given by two points A and B. Additionally it draws 9 marker at the edgepoints, the midpoints of the lines and the center of the rectangle. For each marker a DrawCtrl.CtrlPointKind is set as Tag. So you can identify the marker with CurrentHit.Tag
CtrlRectMarker Draws a rectangle given by two points A and B. It draws marker dependig on "MarkerCount". For each marker a DrawCtrl.CtrlPointKind is set as Tag. So you can identify the marker with CurrentHit.Tag
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 Overrides the Paint-method and sets Penwidth, PenStyle and PenColor.
RemoveChild (inherited from MNComponent) Removes a component.
ToString (inherited from Object) 
Transform (inherited from Entity) Implements ITransform: the transformation will be multiplied by the Matrix T.
UpDate (inherited from Entity) Overrides the UpDate- method and informs the MNDevice, that the contents have changed.
UpDated (inherited from Entity) 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 (inherited from Entity) 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 (inherited from Entity) From draw a OnDraw-event is fired. You can use them. So you don`t have to derive a component.
OnDrawFloat This event is called from DrawFloat
OnPaint (inherited from Entity) 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 (inherited from Entity) 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 ).
DrawFloat Call the drawingmethods of those parts of a sketch, which should be fast changed (For example in a mouse move ). .
Finalize (inherited from Object) 
GetColor Virutal getmethod of the Color-property
GetTransformation (inherited from Entity) GetMethod of the property Transformation
MemberwiseClone (inherited from Object) 
SetColor Virutal setmethod of the Color-property
setDevice Setmethod of the property Device.
setParent (inherited from Entity) Overrides the setParentmethod, because in that case the visibility has changed.
SetTransformation (inherited from Entity) Setmethod of the property Transformation
SetVisible (inherited from Entity) Virtual setmethod of the Visible-property.
