public class GraphController : AbstractViewContent, IGraphController, IMVCANController, IMVCAController, IMVCController, IDisposable, IApplyController, IGraphViewEventSink
The GraphController type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | GraphController | Initializes a new instance of the GraphController class |
| GraphController(GraphDocument) | Creates a GraphController which shows the GraphDocumentgraphdoc. |
Properties| Name | Description | |
|---|---|---|
 | ActiveLayer | Returns the currently active layer. There is always an active layer. |
| AutoZoomFactor | Gets the current zoom factor that would be used for auto zoom, but does not set it. Does not change any member variables. |
| CloseCommand | (Inherited from AbstractViewContent) |
| CloseWithSolution | (Inherited from AbstractViewContent) |
| ContentId |
Gets or sets the content identifier. Here, the content identifier is calculated of the reference hash of the document.
Setting is not implemented here.
(Inherited from AbstractViewContent) |
| CurrentGraphTool | |
| CurrentLayerNumber | Get / sets the currently active layer by number. |
| CurrentPlotNumber | Get / sets the currently active plot by number. |
| Doc | |
| FactorForGraphToMouseCoordinateConversion | Factor for conversion of graph units (in points = 1/72 inch) to mouse coordinates. The resolution used for this is _screenResolutionDpi. |
| IconSource | (Inherited from AbstractViewContent) |
| InfoTip | (Inherited from AbstractViewContent) |
| InitiallyFocusedControl | (Inherited from AbstractViewContent) |
| IsActive |
Gets or sets a value indicating whether the view of this instance is active in the UI.
(Inherited from AbstractViewContent) |
| IsAutoZoomActive | Enables / disable the autozoom feature. |
| IsContentVisible |
Gets a value indicating whether the content of this document window is visible (it is if either IsActive or IsSelected is visible.
(Inherited from AbstractViewContent) |
| IsDirty | (Inherited from AbstractViewContent) |
| IsDisposed | (Inherited from AbstractViewContent) |
| IsDisposeInProgress | (Inherited from AbstractViewContent) |
| IsOverlayPaintingRequired | |
| IsReadOnly |
Gets if the view content is read-only (can be saved only when choosing another file name).
(Inherited from AbstractViewContent) |
| IsSelected |
Gets or sets a value indicating whether the view of this instance is selected (e.g. inside its container).
(Inherited from AbstractViewContent) |
| IsViewOnly |
Gets if the view content is view-only (cannot be saved at all).
(Inherited from AbstractViewContent) |
| IsVisible |
Gets or sets the visibility of the document.
If false, the document tab header is not visible (but the document itself maybe visible !).
If true, the document tab header is visible (if it fits in the bar),
and the document is visible, if it is selected, too.
(Inherited from AbstractViewContent) |
| Margin | Gets or sets the margin. A value of 0 indicates that if autozoom is active, there is no margin around the graph. A value of 1 means that there is a right and left margin of 100 percent of the graph width, and a top and bottom margin of 100 percent of the graph heigth. |
| ModelObject | (Overrides AbstractViewContentModelObject) |
| NonPageAreaColor | Gets the color of the non page area, i.e. the area that not belongs to the graph. |
| NumberOfSelectedObjects | Returns the number of selected objects into this graph. |
| PositionOfViewportsUpperLeftCornerInGraphCoordinates | Gets or sets the position of the view port window's upper left corner in graph coordinates. |
| RootLayer | Returns the layer collection. Is the same as m_GraphDocument.XYPlotLayer. |

| Services | (Inherited from AbstractViewContent) |
| SizeOfGraphWithMargin | Gets the size (in points = 1/72 inch) of the graph with margin (without zoom). |
| SizeOfGraphWithMarginZoomed | Gets the size (in points = 1/72 inch) of the graph with margin with taking into account the current zoom factor. This can be much greater than the actual viewport size, if the zoom factor exceeds the auto zoom factor. |
| Title |

This value will be passed through the string parser before being displayed.
(Inherited from AbstractViewContent) |
