Constructor Detail

PageViewComponentImpl

public PageViewComponentImpl(DocumentViewModel documentViewModel,
                             org.icepdf.core.pobjects.PageTree pageTree,
                             int pageIndex,

Method Detail

setDocumentViewCallback

public void setDocumentViewCallback(DocumentView parentDocumentView)

Description copied from interface: PageViewComponent

Set the parent Document View class which is responsible for drawing and the general management of PageViewComponents for a particular view.

Specified by:

setDocumentViewCallback in interface PageViewComponent

Overrides:

setDocumentViewCallback in class AbstractPageViewComponent

Parameters:

parentDocumentView - type of view, single page, continuous, etc.

paintComponent

protected void paintComponent(java.awt.Graphics g)

Overrides:

paintComponent in class AbstractPageViewComponent

dispose

public void dispose()

Description copied from interface: PageViewComponent

Called to free resources used by this component.

Specified by:

dispose in interface PageViewComponent

setToolMode

public void setToolMode(int viewToolMode)

Sets the tool mode for the current page component implementation. When a tool mode is assigned the respective tool handler is registered and various event listeners are registered.

Parameters:

viewToolMode - view tool modes as defined in DocumentViewMode.DISPLAY_TOOL_*

getAnnotationComponents

public java.util.ArrayList<AbstractAnnotationComponent> getAnnotationComponents()

Gets a list of the annotation components used in this page view.

Returns:

list of annotation components, can be null.

getTextSelectionPageHandler

public TextSelectionPageHandler getTextSelectionPageHandler()

Gets the page components TextSelectionPageHandler. Each page has one and it directly accessed by the TextSelectionViewHandler. All other tools are created/disposed as the tools are selected.

Returns:

page's instance of the text selection handler.

getCurrentToolHandler

public ToolHandler getCurrentToolHandler()

focusGained

public void focusGained(java.awt.event.FocusEvent e)

Specified by:

focusGained in interface java.awt.event.FocusListener

focusLost

public void focusLost(java.awt.event.FocusEvent e)

Specified by:

focusLost in interface java.awt.event.FocusListener

updateView

public void updateView(java.lang.String propertyConstant,
                       java.lang.Object oldValue,
                       java.lang.Object newValue)

Description copied from class: AbstractPageViewComponent

Called from parent controls when a UI control has manipulated the view, property change is picked up and the view is updated accordingly. Responds to PropertyConstants.DOCUMENT_VIEW_ROTATION_CHANGE and PropertyConstants.DOCUMENT_VIEW_ZOOM_CHANGE. If the worker is currently working is is cancel with interrupts.

Specified by:

updateView in interface PageViewComponent

Overrides:

updateView in class AbstractPageViewComponent

Parameters:

propertyConstant - document view change property.

oldValue - old value

newValue - new value

addAnnotation

public void addAnnotation(AnnotationComponent annotation)

Add a new annotation object to this page view component.

Parameters:

annotation - annotation to add.

removeAnnotation

public void removeAnnotation(AnnotationComponent annotationComp)

Remove the specified annotation from this page view.

Parameters:

annotationComp - annotation to be removed.

pageInitializedCallback

public void pageInitializedCallback(org.icepdf.core.pobjects.Page page)

Description copied from interface: PageViewComponent

This callback is called when the page is successfully initialized at which point an implementation may like to work with the page object before the parent method turns. This method should return as quickly as possible.

Specified by:

pageInitializedCallback in interface PageViewComponent

Parameters:

page - page that was just initialized.

pageTeardownCallback

public void pageTeardownCallback()

Description copied from interface: PageViewComponent

This callback is called when a page is scheduled for dispose. This generally only happens when the page goes out of view and it and it's resources are no longer needed. This method in the default implementation is executed on a worker thread. Any AWT work should be queued to run on the AWT thread.

Specified by:

pageTeardownCallback in interface PageViewComponent

refreshAnnotationComponents

public void refreshAnnotationComponents(org.icepdf.core.pobjects.Page page)
