PropertyDialogAction

public class PropertyDialogAction extends SelectionProviderAction (Code)

Standard action for opening a Property Pages Dialog on the currently selected element.

This class may be instantiated; it is not intended to be subclassed.

Generally speaking, this action is useful in pop-up menus because it allows the user to browse and change properties of selected elements. When performed, the action will bring up a Property Pages Dialog containing property pages registered with the workbench for elements of the selected type.

Although the action is capable of calculating if there are any applicable pages for the current selection, this calculation is costly because it require searching the workbench registry. Where performance is critical, the action can simply be added to the pop-up menu. In the event of no applicable pages, the action will just open an appropriate message dialog.

Constructor Summary
public	PropertyDialogAction(Shell shell, ISelectionProvider provider) Creates a new action for opening a property dialog on the elements from the given selection provider.
public	PropertyDialogAction(IShellProvider shell, ISelectionProvider provider) Creates a new action for opening a property dialog on the elements from the given selection provider.

Method Summary
public PreferenceDialog	createDialog() Create the dialog for the receiver.
public boolean	isApplicableForSelection() Returns whether this action is actually applicable to the current selection.
public boolean	isApplicableForSelection(IStructuredSelection selection) Returns whether this action is applicable to the current selection.
public void	run()
public void	selectionChanged(IStructuredSelection selection)

Constructor Detail

PropertyDialogAction
public PropertyDialogAction(Shell shell, ISelectionProvider provider)(Code)
	Creates a new action for opening a property dialog on the elements from the given selection provider. Parameters: shell - the shell in which the dialog will open Parameters: provider - the selection provider whose elements the property dialog willdescribe

PropertyDialogAction
public PropertyDialogAction(IShellProvider shell, ISelectionProvider provider)(Code)
	Creates a new action for opening a property dialog on the elements from the given selection provider. Parameters: shell - provides the shell in which the dialog will open Parameters: provider - the selection provider whose elements the property dialog willdescribe since: 3.1

Method Detail

createDialog
public PreferenceDialog createDialog()(Code)
	Create the dialog for the receiver. If no pages are found, an informative message dialog is presented instead. PreferenceDialog or `null` if no applicable pagesare found. since: 3.1

If it is enabled, it will check with the workbench's property page manager to see if there are any property pages registered for the selected element's type. This method is generally too expensive to use when updating the enabled state of the action on each selection change. `true` if the selection is of size 1 and there areproperty pages for the selected element, and `false`otherwise

isApplicableForSelection
public boolean isApplicableForSelection(IStructuredSelection selection)(Code)
	Returns whether this action is applicable to the current selection.

This method is generally too expensive to use when updating the enabled state of the action on each selection change. Parameters: selection - The selection to test `true` if the selection is of size 1 and there areproperty pages for the selected element, and `false`otherwise
