Method Detail

addCanEditChangedHandler

com.google.gwt.event.shared.HandlerRegistration addCanEditChangedHandler(CanEditChangedHandler handler)

Notification method called when the canEdit setting is modified. Developers may make use of this to toggle between an editable and a read-only appearance of the canvas.

The default behavior is:

• If canvas is a DynamicForm, the form's DynamicForm.canEdit setting is set to canEdit.
• shouldDisableCanvas() is called to determine if the canvas should be disabled.

Standard CanvasItem-based form items may customize the default behavior. For example, a MultiComboBoxItem will hide its comboForm if the readOnlyDisplay is ReadOnlyDisplayAppearance.READONLY or ReadOnlyDisplayAppearance.STATIC and also disable the buttons when made read-only.

Parameters:

handler - the canEditChanged handler

Returns:

HandlerRegistration used to remove this handler
