Constructor Detail

FileOpener

public FileOpener(PageView forView)

FileOpener Constructor

Parameters:

forView - the viewer into which the documents shall be loaded

Method Detail

createReadConfiguration

protected ReadConfiguration createReadConfiguration(File file)

Create a ReadConfigurer for the provided File. This method may be overridden to integrate custom loading logic which may respect loading of Annotations and other things of interest.

The FileOpener will only use one Document generated from the ReadConfigurer. If multiple documents are generated within the ReadConfigurer all but the first will be ignored.

openDocumentFromFile

public void openDocumentFromFile()

Produces a FileDialog and calls openDocumentFromFile(File).

openDocumentFromFile

public void openDocumentFromFile(File fSelected)

Loads a file specified by the parameter supplied.

Parameters:

fSelected - file to load

openDocumentFromFile

public void openDocumentFromFile(String fullName)

Loads a file specified by its name.

Parameters:

fullName - full file name

drop

public void drop(DropTargetDropEvent dtde)

This method will be called when a drag operation has terminated with a drop on a component which DropTarget is registered with a FileOpener instance as DropTargetListener. Within this method the transferable object will be used to load and display a dropped file into the associated viewer.

As DataFlavor only DataFlavor.javaFileListFlavor will be accepted.

Integrator hint: To enable file dropping from GNOME / KDE desktop, you have to implement a Transferable that accepts the text/uri-list format. For further details see Oracle Bug Database, ID 4899516.
