Node selection listener

[maxim.kovalev]

Hi all
Tell me whether there is a listener that is triggered by Oxygen on the node selection?

thanks

Hi Maxim,

You can add an AuthorCaretListener to the Author Editor Access and find the selected node when the caret position is updated:

Code: Select all

authorAccess.getEditorAccess().addAuthorCaretListener(caretListener);

To find if there is a selection in the Author page:

Code: Select all

boolean hasSelection = authorAccess.getEditorAccess().hasSelection();

To find the node which is perfectly surrounded by the current selection in the Author editor, you can call the following method (available in Author Editor Access):

Code: Select all

AuthorNode getFullySelectedNode()

This method was introduced in oXygen version 13.1.

For older oXygen versions, here is a sample of how you can get the fully selected node:

Code: Select all

boolean hasSelection = authorAccess.getEditorAccess().hasSelection();

if (hasSelection) {

  // Find the selection start offset

  int selStart = authorAccess.getEditorAccess().getSelectionStart();

  // Find the selection end offset

  int selEnd  = authorAccess.getEditorAccess().getSelectionEnd();

  // Find if an Author node starts at selection start offset

  OffsetInformation info = authorAccess.getDocumentController().getContentInformationAtOffset(selStart);

  if (info.getPositionType() == OffsetInformation.ON_START_MARKER) {

    // Find if an this node ends at selection end offset

    if (info.getNodeForMarkerOffset().getEndOffset() == selEnd - 1) {

      // This is the the fully selected node

      System.out.println("Fully selected node: " + info.getNodeForMarkerOffset().getName());

    }

  }

}

This is the link to the online Author SDK Javadoc:

Hi Mihaela

boolean hasSelection = authorAccess.getEditorAccess().hasSelection();
I for some reason always returns false

[maxim.kovalev]

boolean hasSelection = authorAccess.getEditorAccess().hasSelection();
only works when you select a node on the top panel, and I wanted to get in contact with the cursor contents

Hi Maxim,

If you just want to find the node at caret position:

Code: Select all

int caretOffset = authorAccess.getEditorAccess().getCaretOffset();

AuthorNode nodeAtCaret = authorAccess.getDocumentController().

  getNodeAtOffset(caretOffset);

sorry =)
the relevant information can be obtained from
authorAccess.getEditorAccess (). addAuthorCaretListener (caretListener);
AuthorCaretEvent arg0.getNode

большое спасибо =)
