Class ControlDecorationSupport

java.lang.Object

org.eclipse.paho.mqtt.ui.support.fieldassist.ControlDecorationSupport

public class ControlDecorationSupport
extends Object

Copied from eclipse SDK, and fixed ControlDecoration dispose which dosen't dispose the decorated image Decorates the underlying controls of the target observables of a ValidationStatusProvider with ControlDecorations mirroring the current validation status. Only those target observables which implement ISWTObservable or IViewerObservable are decorated.

Since:

1.4

Method Detail

create

public static ControlDecorationSupport create(org.eclipse.core.databinding.ValidationStatusProvider validationStatusProvider,
                                              int position)

Creates a ControlDecorationSupport which observes the validation status of the specified ValidationStatusProvider, and displays a ControlDecoration over the underlying SWT control of all target observables that implement ISWTObservable or IViewerObservable.

Parameters:

validationStatusProvider - the ValidationStatusProvider to monitor.

position - SWT alignment constant (e.g. SWT.LEFT | SWT.TOP) to use when constructing ControlDecorationSupport

Returns:

a ControlDecorationSupport which observes the validation status of the specified ValidationStatusProvider, and displays a ControlDecoration over the underlying SWT control of all target observables that implement ISWTObservable or IViewerObservable.

create

public static ControlDecorationSupport create(org.eclipse.core.databinding.ValidationStatusProvider validationStatusProvider,
                                              int position,
                                              org.eclipse.swt.widgets.Composite composite)

Creates a ControlDecorationSupport which observes the validation status of the specified ValidationStatusProvider, and displays a ControlDecoration over the underlying SWT control of all target observables that implement ISWTObservable or IViewerObservable.

Parameters:

validationStatusProvider - the ValidationStatusProvider to monitor.

position - SWT alignment constant (e.g. SWT.LEFT | SWT.TOP) to use when constructing ControlDecoration instances.

composite - the composite to use when constructing ControlDecoration instances.

Returns:

a ControlDecorationSupport which observes the validation status of the specified ValidationStatusProvider, and displays a ControlDecoration over the underlying SWT control of all target observables that implement ISWTObservable or IViewerObservable.

create

public static ControlDecorationSupport create(org.eclipse.core.databinding.ValidationStatusProvider validationStatusProvider,
                                              int position,
                                              org.eclipse.swt.widgets.Composite composite,
                                              ControlDecorationUpdater updater)

Creates a ControlDecorationSupport which observes the validation status of the specified ValidationStatusProvider, and displays a ControlDecoration over the underlying SWT control of all target observables that implement ISWTObservable or IViewerObservable.

Parameters:

validationStatusProvider - the ValidationStatusProvider to monitor.

position - SWT alignment constant (e.g. SWT.LEFT | SWT.TOP) to use when constructing ControlDecoration instances.

composite - the composite to use when constructing ControlDecoration instances.

updater - custom strategy for updating the ControlDecoration(s) whenever the validation status changes.

Returns:

a ControlDecorationSupport which observes the validation status of the specified ValidationStatusProvider, and displays a ControlDecoration over the underlying SWT control of all target observables that implement ISWTObservable or IViewerObservable.

dispose

public void dispose()

Disposes this ControlDecorationSupport, including all control decorations managed by it. A ControlDecorationSupport is automatically disposed when its target ValidationStatusProvider is disposed.
