Method Detail

getAttributeValue

public abstract java.lang.String getAttributeValue(EditedAttribute attribute,
                                                   java.lang.Object parentComponent)
                                            throws CancelledByUserException

Get a value for the current attribute.

Parameters:

attribute - The attribute to be edited.

parentComponent - The parent component, usually the table in which the user double clicked the value. Used for example to find the parent window/shell when creating dialogs.
It is very important to set the parent of the dialog used as custom editor when showing it from oXygen's in-place attribute-editing dialog in the Author page. This needs to be done in order for oXygen's in-place attribute editor not to disappear when presenting the custom attribute value editor.
The code that creates a simple input dialog as a custom editor, with the proper parent dialog, for the stand-alone oXygen, looks as following:

 public String getAttributeValue(EditedAttribute attribute, Object parentComponent)
     throws CancelledByUserException {
   String attrValue = null;
   PluginWorkspace pluginWorkspace = PluginWorkspaceProvider.getPluginWorkspace();
   Platform platform = pluginWorkspace.getPlatform();
   if (platform == Platform.STANDALONE) {
     // Find the parent window
     Component parent = (Component) parentComponent;
     while (!(parent instanceof Window)) {
       parent = parent.getParent();
     }
     attrValue = JOptionPane.showInputDialog(
         parent,
         "Set a new value for \"" + attribute.getAttributeQName() + "\":");
   }
   return attrValue;
 }
 

For the Eclipse plug-in, the code changes into:

 public String getAttributeValue(EditedAttribute attribute, Object parentComponent)
     throws CancelledByUserException {
   String attrValue = null;
   PluginWorkspace pluginWorkspace = PluginWorkspaceProvider.getPluginWorkspace();
   Platform platform = pluginWorkspace.getPlatform();
   if (platform == Platform.ECLIPSE) {
     // Find the parent shell
     Control parent = (Control) parentComponent;
     while (!(parent instanceof Shell)) {
       parent = parent.getParent();
     }
     InputDialog inputDialog = new InputDialog(
         (Shell) parent,
         "Edit attribute",
         "Set a new value for \"" + attribute.getAttributeQName() + "\":",
         null,
         null);
     if (inputDialog.open() == org.eclipse.jface.window.Window.OK) {
       // OK pressed. Get the value.
       attrValue = inputDialog.getValue();
     }
   }
   return attrValue;
 }
 

Returns:

The proposed value. Returning the empty string will commit it as a value, returning null will remove the attribute, while throwing a CancelledByUserException will cancel the editing.

Throws:

CancelledByUserException - When the user cancels the editing.
