Define the standard CommandBindings and InputBindings for all of the predefined diagram Commands. [WPF only]

This overridable predicate controls whether or not the Copy command is executed.

Retorna: by default, this returns true if AllowCopy is true, if AllowClipboard is true, and if there are some selected parts (SelectedParts).

This overridable predicate controls whether or not the Cut command is executed.

Retorna: by default, this returns true if the diagram is not IsReadOnly, if AllowCopy is true, if AllowDelete is true, if AllowClipboard is true, if there are some selected parts (SelectedParts), and if the model is Modifiable.

This overridable predicate controls whether or not the DecreaseZoom command is executed.

param

the factor by which to decrease the zoom; this defaults to 5% (1/ZoomFactor)

Retorna: by default, this returns true if AllowZoom is true, and if the is a value greater than zero.

This overridable predicate controls whether or not the Group command is executed.

Retorna: By default, this returns true: if the PrototypeGroup data is not null, if the diagram is not IsReadOnly, if AllowInsert is true, if AllowGroup is true, if the model is an ISubGraphModel that is modifiable, and if there are any selected nodes that can be CanGroup'ed.

This overridable predicate controls whether or not the IncreaseZoom command is executed.

param

the factor by which to increase the zoom; this defaults to 5% (ZoomFactor)

Retorna: by default, this returns true if AllowZoom is true, and if the is a value greater than zero.

This overridable predicate controls whether or not the Paste command is executed.

Retorna: by default, this returns true if the diagram is not IsReadOnly, if AllowInsert is true, if AllowClipboard is true, if the clipboard has data of the format given by the diagram's model's DataFormat, and if the model is Modifiable.

This overridable predicate controls whether or not the Print command is executed.

Retorna: By default, this returns true if AllowPrint is true and there is a PrintManager.

This overridable predicate controls whether or not the Redo command is executed.

Retorna: by default, this returns true if the diagram is not IsReadOnly, if AllowUndo is true, and if the diagram's model's UndoManagerCanRedo predicate returns true.

This overridable predicate controls whether or not the SelectAll command is executed.

Retorna: by default, this returns true if AllowSelect is true.

This overridable predicate controls whether or not the StopCommand is executed.

Retorna: by default, this returns true

This overridable predicate controls whether or not the Undo command is executed.

Retorna: by default, this returns true if the diagram is not IsReadOnly, if AllowUndo is true, and if the diagram's model's UndoManagerCanUndo predicate returns true.

This overridable predicate controls whether or not the Ungroup command is executed.

Retorna: by default, this returns true if the diagram is not IsReadOnly, if AllowDelete is true, if AllowUngroup is true, if the model is an ISubGraphModel that is modifiable, and if there are any selected Groups that can be CanUngroup'ed.

This overridable predicate controls whether or not the Zoom command is executed.

param

the new Scale value; this defaults to 1

Retorna: by default, this returns true if AllowZoom is true, and if the is a value greater than zero.

This overridable predicate controls whether or not the ZoomToFit command is executed.

Retorna: by default, this returns true if AllowZoom is true.

Copy the currently SelectedParts from the Diagram into the clipboard.

This writes the given data collection to the clipboard using the diagram's model's DataFormat.

coll

Execute a Copy followed by a Delete.

Decrease the Diagram.Panel.Scale by the given factor.

param

The factor by which to decrease the zoom. This should be less than one but greater than zero; it defaults to 5% (1/ZoomFactor).

Delete the currently SelectedParts from the Diagram.

This is called by the ToolManager.

e

This is called by the ToolManager.

e

Start in-place editing of the first TextBlock of the selected part.

Create a new group node and add the selected parts to that new group.

Increase the Diagram.Panel.Scale by the given factor.

param

The factor by which to increase the zoom. This should be greater than one; it defaults to 5% (ZoomFactor).

Copy the contents of the clipboard as new nodes and links in this diagram, and make those new parts the new selection.

This reads a data collection from the clipboard using the diagram's model's DataFormat.

Retorna: null if the Clipboard does not contain any data of the given format

Print the diagram by showing a PrintDialog and then calling the PrintManager's PrintDialog) method.

This method just calls UIElement.RaiseEvent on the Diagram and returns whether the event was handled.

evt

Retorna: true if the event was raised and it was Handled

Call Diagram.Model.UndoManager.Redo.

Remove all of the standard diagram command bindings and input bindings. [WPF only]

Select all of the Nodes and Links in the Diagram.

Cancel the operation of the current CurrentTool.

Call Diagram.Model.UndoManager.Undo.

For each selected node that is a group, remove the group without removing its members from the diagram.

Set the Scale property of the Panel to the given value.

param

The new scale value. This should be greater than zero; it defaults to 1.

Change the Scale such that the whole diagram/document fits into the viewport; or if this command had just executed before, restore the original viewport.
