DiagramClientView Class

Initializes a new instance of the DiagramClientView class.

Gets or sets the active mouse action for this DiagramClientView.

(Note: Override the cursor in the MouseAction-derived classes or ShapeElement-derived classes instead.)

Gets or sets the Diagram object associated with this DiagramClientView.

Display resolution X in dots per inch. MAY BE STALE if display resolution has changed since last call to UpdateRatios (via W2D/D2W calls). It is likely not to have changed and good enough for most purposes (creation was for bump-scrolling) as it avoids creating another graphics as does GetWorldUnitsPerDeviceUnits.

Gets or sets the horizontal scroll position in scroll units.

The shape that InvokeDragDrop() will drop onto, or null if there is no drop target.

Gets the lower limit of values of the scrollable range in scroll units.

Gets the lower limit of values of the scrollable range in scroll units.

Gets the minimum zoom allowed.

Gets or sets the amount to delay the raising of the shape MouseHover event. Units are in milliseconds.

Gets the number of scroll units to scroll for scrolling a page.

Gets the number of scroll units to scroll for each mouse wheel event.

Gets the selection for the DiagramClientView.

Gets the ShadowBitmap associated with this design surface.

Gets or sets a value indicating whether this control should take the focus on a DragOver event.

Gets or sets the vertical scroll position in scroll units.

Gets the bounds of the viewport in world units relative to the top-left of the Diagram.

Gets the top-left corner of the viewport relative to the top-left of the Diagram in world units.

Gets the size of the viewport in world units.

Gets the scaling factor.

Returns a value indicating whether the key translates to a command.

Creates a new accessibility object for this control.

Converts a point in device units to world units using the view's current zoom factor. The device units are relative to the DiagramClientView's top-left. The world units are relative to the diagram's top-left.

Converts a rectangle in device units to world units using the view's current zoom factor. The device units are relative to the DiagramClientView's top-left. The world units are relative to the diagram's top-left.

Converts a size in device units to world units using the specified zoom factor.

Converts a size in device units to world units using the view's current zoom factor.

Disables bump scrolling.

Releases all resources, managed and unmanaged, related to this class.

Enables bump scrolling after the specified initial delay in milliseconds.

Ensures that the specified shapes are visible in the view. This may require changes to the scroll positions and to the zoom.

Ensures that the specified rectangle is visible in the view. This may require changes to the scroll positions and to the zoom.

Ensures that the specified rectangle is visible in the view.
Based on VisiblePreference setting for the Diagram, the RectangleD will be brought into view. ZoomOut may be used to fit the RectangleD iff MinimalScrollWithNoZoom VisiblePreference is not selected for this Diagram. Scrolling may be used to fit the RectangleD and depending on the VisiblePreference setting selected for the diagram, either the center of the Rectangle will be brought into view center or minimal scrolling that is required to bring the Rectangle into view will be done.

The horizontal amount (in world units) by which a nudge operation can move a shape.

The vertical amount (in world units) by which a nudge operation can move a shape.

Retrieves the potential mouse action that should be made active on the very next MouseDown event if the MouseDown event occurs at the specified point.

Invalidates the specified rectangle in world units.

Invokes a DragDrop of the supplied DragEventArgs onto the currently selected Shape.

Determines whether the specified key is a regular input key or a special key that requires preprocessing.

ManuallyRoute the line segment of the primary LinkShape in the selection.

Repositions the selected shapes by the specified delta in world units.
