observeDelayedValue
public static <T> IViewerObservableValue<T> observeDelayedValue(int delay, IViewerObservableValue<T> observable)
Returns an observable which delays notification of value change events fromobservableuntildelaymilliseconds have passed since the last change event, or until a FocusOut event is received from the underlying viewer control (whichever happens earlier). This class helps to delay validation until the user stops changing the value (e.g. until a user stops changing a viewer selection). To notify about pending changes, the returned observable value will fire a stale event when the wrapped observable value fires a change event, but this change is being delayed.- Parameters:
delay- the delay in millisecondsobservable- the observable being delayed- Returns:
- an observable which delays notification of value change events
from
observableuntildelaymilliseconds have passed since the last change event. - Since:
- 1.3

observeSingleSelection
@Deprecated public static IObservableValue observeSingleSelection(ISelectionProvider selectionProvider)
Deprecated.useViewerPropertiesinsteadReturns an observable value that tracks the current selection of the given selection provider. If the selection provider provides selections of typeIStructuredSelection, the observable value will be the first element of the structured selection as returned byIStructuredSelection.getFirstElement().- Parameters:
selectionProvider-- Returns:
- the observable value tracking the (single) selection of the given selection provider
-
observeSinglePostSelection
@Deprecated public static IObservableValue observeSinglePostSelection(IPostSelectionProvider selectionProvider)
Deprecated.useViewerPropertiesinsteadReturns an observable value that tracks the current post selection of the given post selection provider. If the selection provider provides selections of typeIStructuredSelection, the observable value will be the first element of the structured selection as returned byIStructuredSelection.getFirstElement().- Parameters:
selectionProvider- The selection provider on which to track the post selection.- Returns:
- the observable value tracking the (single) post selection of the given post selection provider
- Since:
- 1.4
-
observeMultiSelection
@Deprecated public static IObservableList observeMultiSelection(ISelectionProvider selectionProvider)
Deprecated.useViewerPropertiesinsteadReturns an observable list that tracks the current selection of the given selection provider. Assumes that the selection provider provides selections of typeIStructuredSelection. Note that the observable list will not honor the full contract ofjava.util.Listin that it may delete or reorder elements based on what the selection provider returns fromISelectionProvider.getSelection()after having calledISelectionProvider.setSelection(org.eclipse.jface.viewers.ISelection)based on the requested change to the observable list. The affected methods areadd,addAll, andset.- Parameters:
selectionProvider-- Returns:
- the observable value tracking the (multi) selection of the given selection provider
- Since:
- 1.2
-
observeMultiPostSelection
@Deprecated public static IObservableList observeMultiPostSelection(IPostSelectionProvider selectionProvider)
Deprecated.useViewerPropertiesinsteadReturns an observable list that tracks the current post selection of the given post selection provider. Assumes that the selection provider provides selections of typeIStructuredSelection. Note that the observable list will not honor the full contract ofjava.util.Listin that it may delete or reorder elements based on what the selection provider returns fromISelectionProvider.getSelection()after having calledISelectionProvider.setSelection(org.eclipse.jface.viewers.ISelection)based on the requested change to the observable list. The affected methods areadd,addAll, andset.- Parameters:
selectionProvider- The selection provider on which to track the post selection.- Returns:
- the observable value tracking the (multi) post selection of the given post selection provider
- Since:
- 1.4
-
observeSingleSelection
@Deprecated public static IViewerObservableValue observeSingleSelection(Viewer viewer)
Deprecated.useViewerPropertiesinsteadReturns an observable value that tracks the current selection of the given viewer. If the viewer provides selections of typeIStructuredSelection, the observable value will be the first element of the structured selection as returned byIStructuredSelection.getFirstElement().- Parameters:
viewer- the viewer- Returns:
- the observable value tracking the (single) selection of the given viewer
- Since:
- 1.2
-
observeSinglePostSelection
@Deprecated public static IViewerObservableValue observeSinglePostSelection(StructuredViewer viewer)
Deprecated.useViewerPropertiesinsteadReturns an observable value that tracks the current post selection of the given structured viewer. If the viewer provides selections of typeIStructuredSelection, the observable value will be the first element of the structured selection as returned byIStructuredSelection.getFirstElement().- Parameters:
viewer- The viewer on which to track the post selection.- Returns:
- the observable value tracking the (single) post selection of the given structured viewer
- Since:
- 1.4
-
observeMultiSelection
@Deprecated public static IViewerObservableList observeMultiSelection(Viewer viewer)
Deprecated.useViewerPropertiesinsteadReturns an observable list that tracks the current selection of the given viewer. Assumes that the viewer provides selections of typeIStructuredSelection. Note that the observable list will not honor the full contract ofjava.util.Listin that it may delete or reorder elements based on what the viewer returns fromISelectionProvider.getSelection()after having calledISelectionProvider.setSelection(org.eclipse.jface.viewers.ISelection)based on the requested change to the observable list. The affected methods areadd,addAll, andset.- Parameters:
viewer-- Returns:
- the observable value tracking the (multi) selection of the given selection provider
- Since:
- 1.2
-
observeMultiPostSelection
@Deprecated public static IViewerObservableList observeMultiPostSelection(StructuredViewer viewer)
Deprecated.useViewerPropertiesinsteadReturns an observable list that tracks the current post selection of the given structured viewer. Assumes that the viewer provides selections of typeIStructuredSelection. Note that the observable list will not honor the full contract ofjava.util.Listin that it may delete or reorder elements based on what the viewer returns fromISelectionProvider.getSelection()after having calledISelectionProvider.setSelection(org.eclipse.jface.viewers.ISelection)based on the requested change to the observable list. The affected methods areadd,addAll, andset.- Parameters:
viewer- The viewer on which to track the post selection.- Returns:
- the observable value tracking the (multi) post selection of the given structured viewer
- Since:
- 1.4
-
observeInput
@Deprecated public static IObservableValue observeInput(Viewer viewer)
Deprecated.useViewerPropertiesinsteadReturns an observable value that tracks the input of the given viewer.The returned observer is blind to changes in the viewer's input unless its
IObservableValue.setValue(Object)method is called directly.- Parameters:
viewer- the viewer to observe- Returns:
- an observable value tracking the input of the given viewer
- Since:
- 1.2
-
observeCheckedElements
@Deprecated public static IObservableSet observeCheckedElements(ICheckable checkable, Object elementType)
Deprecated.useViewerPropertiesinsteadReturns an observable set that tracks the checked elements of the givenICheckable.- Parameters:
checkable-ICheckablecontaining the checked elements to trackelementType- element type of the returned set- Returns:
- an observable set tracking the checked elements of the given checkable.
- Since:
- 1.2
-
observeCheckedElements
@Deprecated public static IViewerObservableSet observeCheckedElements(CheckboxTableViewer viewer, Object elementType)
Deprecated.useViewerPropertiesinsteadReturns an observable set that tracks the checked elements of the given viewer. Assumes that the viewer implementsICheckable.- Parameters:
viewer-CheckboxTableViewercontaining the checked elements to track.elementType- element type of the returned set- Returns:
- an observable set that tracks the checked elements of the given viewer.
- Since:
- 1.2

- 1.2
-
observeFilters
@Deprecated public static IViewerObservableSet observeFilters(StructuredViewer viewer)
Deprecated.useViewerPropertiesinsteadReturns an observable set that tracks the filters of the given viewer. Note that the returned set will not track changes that are made using direct API on StructuredViewer (by callingaddFilter(),removeFilter(), orsetFilters()) -- it is assumed that filters are only changed through the returned set.- Parameters:
viewer- viewer containing the filters to be tracked- Returns:
- an observable set that tracks the filters of the given viewer.
