Method Detail

getRendererComponent

public java.lang.Object getRendererComponent(AuthorInplaceContext context)

Description copied from interface: InplaceRenderer

Initialize the renderer with the given context and returns the component. It's up to the caller to use the renderer to paint.

Specified by:

getRendererComponent in interface InplaceRenderer

Parameters:

context - The editing context.

Returns:

The renderer. A java.awt.Component implementation.

See Also:

InplaceRenderer.getRendererComponent(ro.sync.ecss.extensions.api.editor.AuthorInplaceContext)

getRenderingInfo

public RendererLayoutInfo getRenderingInfo(AuthorInplaceContext context)

Description copied from interface: InplaceRenderer

Returns the rendering layout info. This contains information about the baseline and the size in a certain context. The baseline is measured from the top of the component. Because a renderer is reused, when this call is received, the renderer must re-initialize itself from the given context.

Specified by:

getRenderingInfo in interface InplaceRenderer

Parameters:

context - The editing context.

Returns:

The rendering layout info.

See Also:

InplaceRenderer.getRenderingInfo(ro.sync.ecss.extensions.api.editor.AuthorInplaceContext)

getEditorComponent

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

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.

mouseLocation - 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.

requestFocus

public 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 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 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

Overrides:

commitValue in class AbstractInplaceEditor

See Also:

InplaceEditor.commitValue()

cancelEditing

public 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()

getDescription

public java.lang.String getDescription()

Specified by:

getDescription in interface Extension

Returns:

The description of the extension.

See Also:

Extension.getDescription()

getScrollRectangle

public 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()

getTooltipText

public java.lang.String getTooltipText(AuthorInplaceContext context,
                                       int x,
                                       int y)

Description copied from interface: InplaceRenderer

Gets a tooltip text to be presented when the cursor is over this renderer. Because a renderer is reused, when this called is received, the renderer must re-initialize itself from the given context.

Specified by:

getTooltipText in interface InplaceRenderer

Parameters:

context - The editing context.

x - The x coordinate relative to the renderer bounds.

y - The y coordinate relative to the renderer bounds.

Returns:

A tooltip text or null if no tooltip.

See Also:

InplaceRenderer.getTooltipText(ro.sync.ecss.extensions.api.editor.AuthorInplaceContext, int, int)

getCursorType

public CursorType getCursorType(AuthorInplaceContext context,
                                int x,
                                int y)

Description copied from interface: InplaceRenderer

Get a cursor to be used when the user hovers with the mouse over this renderer. For a more complex renderer, the given X,Y coordinates can be used to decide what cursor to return.

Specified by:

getCursorType in interface InplaceRenderer

Parameters:

context - The editing context. Useful if the renderer is a more complex one, like a text field with an associated button and wants to provide different cursors when the cursor is over the textfield or over the button. In this case the renderer will have to initialize itself with this context in order to decide what the cursor is hovering.

x - The x coordinate relative to the renderer bounds.

y - The y coordinate relative to the renderer bounds.

Returns:

The type of cursor to be used or null to let the viewport decide.

See Also:

InplaceRenderer.getCursorType(ro.sync.ecss.extensions.api.editor.AuthorInplaceContext, int, int)

getCursorType

public CursorType getCursorType(int x,
                                int y)

Description copied from interface: InplaceRenderer

Get a cursor to be used when the user hovers with the mouse over this renderer. For a more complex renderer, the given X,Y coordinates can be used to decide what cursor to return. We recommend using InplaceRenderer.getCursorType(AuthorInplaceContext, int, int) as you can use the provided context to get additional information.

Specified by:

getCursorType in interface InplaceRenderer

Parameters:

x - The x coordinate relative to the renderer bounds.

y - The y coordinate relative to the renderer bounds.

Returns:

The type of cursor to be used or null to let the viewport decide.

See Also:

InplaceRenderer.getCursorType(int, int)

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

Overrides:

refresh in class AbstractInplaceEditor

Parameters:

context - An updated editing context for this editor.
