A minimap control that can position the viewport, and zoom in and out.
public class Minimap : ItemsControl public Minimap(); Gets or sets whether panning cancellation is allowed (see Nodify.Interactivity.EditorGestures.MinimapGestures.CancelAction).
public static bool AllowPanningCancellation { get; set; } Property Value
The area covered by the items and the viewport rectangle in graph space.
public Rect Extent { get; set; } Property Value
protected InputProcessor InputProcessor { get; set; } Property Value
Whether the user is currently panning the minimap.
protected bool IsPanning { get; set; } Property Value
Whether the minimap can move and zoom the viewport.
public bool IsReadOnly { get; set; } Property Value
The area covered by the MinimapItems in graph space.
public Rect ItemsExtent { get; set; } Property Value
Gets the panel that holds all the MinimapItems.
protected Panel ItemsHost { get; set; } Property Value
The max position from the NodifyEditor.ItemsExtent that the viewport can move to.
public Size MaxViewportOffset { get; set; } Property Value
Gets the current mouse location in graph space coordinates (relative to the Minimap.ItemsHost).
public Point MouseLocation { get; set; } Property Value
Whether the minimap should resize to also display the whole viewport.
public bool ResizeToViewport { get; set; } Property Value
public Point ViewportLocation { get; set; } Property Value
public Size ViewportSize { get; set; } Property Value
Gets or sets the style to use for the viewport rectangle.
public Style ViewportStyle { get; set; } Property Value
Starts the panning operation from the specified location. Call Nodify.Minimap.EndPanning to end the panning operation.
public void BeginPanning(); public void BeginPanning(Point location); Parameters
location Point
Cancels the current panning operation and reverts the viewport to its initial location if Minimap.AllowPanningCancellation is true. Otherwise, it ends the panning operation by calling Nodify.Minimap.EndPanning.
public void CancelPanning(); Ends the current panning operation, retaining the current Minimap.ViewportLocation.
public void EndPanning(); protected override DependencyObject GetContainerForItemOverride(); Returns
Translates the event location to graph space coordinates (relative to the Minimap.ItemsHost).
public Point GetLocationInsideMinimap(MouseEventArgs args); Parameters
args MouseEventArgs: The mouse event.
Returns
Point: A location inside the minimap
protected override bool IsItemItsOwnContainerOverride(object item); Parameters
