                             GUIControl guiControl)

ViewportWindowManager

public ViewportWindowManager(javax.swing.JDesktopPane desktop,
                             J3DBase base,
                             GUIControl guiControl,
                             SelectionList list)

Method Detail

setViewportsEventHandler

public void setViewportsEventHandler(ViewportsEventHandler handler)

setViewInViewport

public void setViewInViewport(int viewportIndex,
                              VcView view)

Changes the view shown by a certain viewport.

Parameters:

viewportIndex - index of viewport whose view will be changed.

view - new view to be shown by viewport. Must be non null.

Throws:

java.lang.IndexOutOfBoundsException - if viewportIndex is invalid.

moveViewportToFront

public void moveViewportToFront(Viewport viewport)

Moves input Viewport to front.

addViewport

public void addViewport(VcView view)

Adds a new viewport window to workspace.

Parameters:

view - VcView that will be shown by new viewport window.

getNumberOfViewports

public int getNumberOfViewports()

Returns the number of active viewports

getListOfFrames

public java.util.List getListOfFrames()

Returns a list of active ViewportFrames

setViewportLocation

public void setViewportLocation(int viewportIndex,
                                boolean internal,
                                int x,
                                int y,
                                int width,
                                int height)

sceneObjectsChanged

public void sceneObjectsChanged(SceneObjectsChangedEvent event)

Method from SceneObjectsChangeListener interface. ViewportWindowManager will only care about addition/removal of VcView objects. Then it will propagate the changes to the viewports.

Specified by:

sceneObjectsChanged in interface SceneObjectsChangeListener

Parameters:

event - signals changes in the scene graph.

vcObjectChanged

public void vcObjectChanged(VcObjectEvent event)

Method from VcObjectChangeListener interface. Necessary to filter changes made to VcView objects and propagate them to viewport windows.

Specified by:

vcObjectChanged in interface VcObjectChangeListener

Parameters:

event - Signals changes made to objects in the scene graph.

printListOfViews

public void printListOfViews()

getViewportByLabel

public Viewport getViewportByLabel(java.lang.String viewName)

Returns a reference to a viewport given its name. If there is no viewport whose name coincides with the input parameter the method returns null;

Parameters:

viewName - name of the view to be retrieved.

Returns:

a reference to the viewport if it exists, null otherwise.

enableMessageInAllViewports

public void enableMessageInAllViewports(java.lang.String s)

setCursorInViewports

public void setCursorInViewports(TransformType type)

disableMessageInAllViewports

public void disableMessageInAllViewports()

setPickingInViewports

public void setPickingInViewports(boolean pickEnable)

setSelectionList

public void setSelectionList(SelectionList list)
