ro.sync.ecss.extensions.api.editor.AbstractInplaceEditorWrapper

All Implemented Interfaces:

InplaceEditor, Extension

@API(type=EXTENDABLE,
     src=PUBLIC)
public abstract class AbstractInplaceEditorWrapper
extends java.lang.Object
implements InplaceEditor

It can be used when more than one editor types are needed depending on the received context and it can choose at runtime an appropriate editor implementation. For example if in the CSS oxy_editor() function we have a test parameter with more possible values and we must provide a different editor implementation for each one.

Since:

14.1

Method Detail

getDescription

public java.lang.String getDescription()

Specified by:

getDescription in interface Extension

Returns:

The description of the extension.

See Also:

Extension.getDescription()

createEditor

protected abstract InplaceEditor createEditor(AuthorInplaceContext context)

Depending of the received context, create an editor.

Parameters:

context - Editing context.

Returns:

An in-place editor.

getEditorComponent

public final java.lang.Object getEditorComponent(AuthorInplaceContext context,
                                                 Rectangle allocation,
                                                 Point mouseInvocationLocation)

Description copied from interface: InplaceEditor

Prepare and return the editor component.

Specified by:

getEditorComponent in interface InplaceEditor

Parameters:

context - The context where the editor will be used.

allocation - The bounds where the editor will be shown. This is normally the bounds of the box in which the value being edited is rendered. If the editor requires to be presented in different bounds it should alter this parameter. The X,Y coordinates are relative to the parent in which the editor will be added.

mouseInvocationLocation - if the editor was requested using the mouse this parameter represents the X,Y location where the event took place. It is relative to the parent in which the editor will be added. null if the editor wasn't requested through mouse interaction.

OBS: This is the very first call received by an editor. This ensures that the editor is properly initialized for the subsequent calls (like a InplaceEditor.requestFocus() call).
OBS: An editor implementation will have to add listeners onto itself like:

• a KeyListener for handling key events like: ENTER to stop editing (by calling InplaceEditingListener.editingStopped(EditingEvent)) and ESCAPE to cancel it (by calling InplaceEditingListener.editingCanceled()).
• a FocusListener to stop editing when the focus is given to a component that is not part of the editor (by calling InplaceEditingListener.editingStopped(EditingEvent)).
• a DocumentListener to fire InplaceEditingListener.editingOccured() events (If the editor has a document).

Returns:

The component that performs the editing. For the Standalone distribution this should be a java.awt.JComponent implementation. For the Eclipse plugin distribution, an org.eclipse.swt.widgets.Control is expected.

getScrollRectangle

public final Rectangle getScrollRectangle()

Description copied from interface: InplaceEditor

Returns a rectangle that should be made visible after the editor is shown. The coordinate should be relative to the editor itself. The default behavior is to make the entire editor visible but if the editor is bigger than the viewport the visible part might not be the right one. For example is the editor is a text field the caret might not be visible. This is when this method is useful. The caret rectangle should be returned so that the part of the editor with the caret is presented.

Specified by:

getScrollRectangle in interface InplaceEditor

Returns:

A rectangle to be made visible or null to make the entire editor visible.

See Also:

InplaceEditor.getScrollRectangle()

addEditingListener

public final void addEditingListener(InplaceEditingListener editingListener)

Description copied from interface: InplaceEditor

Adds a listener to receive edit notifications: - InplaceEditingListener.editingCanceled() to remove the editor and cancel the edit operation. - InplaceEditingListener.editingOccured() to signal modification in the editor. This event marks the editor as dirty and it's value will be committed when a InplaceEditingListener.editingStopped(EditingEvent) is received. - InplaceEditingListener.editingStopped(EditingEvent) to end editing and commit it's value if needed. The value is usually committed ONLY if a InplaceEditingListener.editingOccured() was fired. See InplaceEditingListener.editingStopped(EditingEvent) for more information.

Specified by:

addEditingListener in interface InplaceEditor

Parameters:

editingListener - Editing listener.

See Also:

InplaceEditor.addEditingListener(ro.sync.ecss.extensions.api.editor.InplaceEditingListener)

requestFocus

public final void requestFocus()

Description copied from interface: InplaceEditor

Requests focus inside the editing component.

Specified by:

requestFocus in interface InplaceEditor

See Also:

InplaceEditor.requestFocus()

getValue

public final java.lang.Object getValue()

Description copied from interface: InplaceEditor

Gets the value that the user entered.

Specified by:

getValue in interface InplaceEditor

Returns:

The value that the user entered.

See Also:

InplaceEditor.getValue()

stopEditing

public final void stopEditing()

Description copied from interface: InplaceEditor

Stops the editing and commits the current value. The editor should release any held resources and notify InplaceEditingListener.editingStopped(EditingEvent). OBS: The current value will be committed only if at least one InplaceEditingListener.editingOccured() event was issued before this moment.

Specified by:

stopEditing in interface InplaceEditor

See Also:

InplaceEditor.stopEditing()

commitValue

public void commitValue()

Description copied from interface: InplaceEditor

Commit the given value inside the document without stopping the editing. Will only commit if a new string value is provided and only if the value that must be committed is different from the current value.

Specified by:

commitValue in interface InplaceEditor

See Also:

InplaceEditor.commitValue()

cancelEditing

public final void cancelEditing()

Description copied from interface: InplaceEditor

Cancels the editing process. The editor should release any held resources and notify InplaceEditingListener.editingCanceled().

Specified by:

cancelEditing in interface InplaceEditor

See Also:

InplaceEditor.cancelEditing()

removeEditingListener

public final void removeEditingListener(InplaceEditingListener editingListener)

Description copied from interface: InplaceEditor

Removes a listener that receives editing events.

Specified by:

removeEditingListener in interface InplaceEditor

Parameters:

editingListener - Editing listener.

See Also:

InplaceEditor.removeEditingListener(ro.sync.ecss.extensions.api.editor.InplaceEditingListener)

refresh

public void refresh(AuthorInplaceContext context)

Description copied from interface: InplaceEditor

While this editor is inside an editing session a document change was detected that didn't originated form this editor. In this situation it might be good for the editor to refresh the presented data.

Currently this method is called if:

• This editor edits an attribute and the same attribute was externally modified. In this situation is recommended for the editor to update the current value.

Specified by:

refresh in interface InplaceEditor

Parameters:

context - An updated editing context for this editor.

See Also:

InplaceEditor.refresh(ro.sync.ecss.extensions.api.editor.AuthorInplaceContext)

insertContent

public boolean insertContent(java.lang.String xmlContent)

Description copied from interface: InplaceEditor

An insert text event was received by the author page and redirected to this currently active form control. The form control should insert this text as it sees fit. For example a text field might insert it at the caret position. An example when this event comes is when the user uses the Character Map Dialog to insert characters directly into a form control.

Specified by:

insertContent in interface InplaceEditor

Parameters:

xmlContent - Content to be inserted.

Returns:

true if the event was handled or false if the form control can do nothing with the string. For example a text field can insert the text inside it but a check box form control can do nothing with it. If false is returned the form control editing session will be stopped and the author page will handle the event instead.
