Methods Summary
public final void	addWindow(org.eclipse.swt.widgets.Shell shell) Adds a shell to the shell manager. If the shell is already managed, it is not added again. Note: This method must be invoked by the SWT display thread param shell A SWT Shell //Debug.out("Invoked by thread " + Thread.currentThread().getName()); if(shells.contains(shell)) {return;} shells.add(shell); notifyAddListeners(shell); shell.addDisposeListener(new DisposeListener() { public void widgetDisposed(DisposeEvent event) { try { removeWindow(shell); } catch (Exception e) { Logger.log(new LogEvent(LogIDs.GUI, "removeWindow", e)); } } }); shell.addListener(SWT.Show, new Listener() { public void handleEvent(Event event) { Utils.verifyShellRect(shell, false); } });
public final void	addWindowAddedListener(org.eclipse.swt.widgets.Listener listener) Adds a listener that will be invoked when a shell has been added to the ShellManager The listener and the shell will automatically be removed when the shell is disposed param listener A SWT Listener addHandlers.add(listener);
public final void	addWindowRemovedListener(org.eclipse.swt.widgets.Listener listener) Adds a listener that will be invoked when a shell has been removed from the ShellManager param listener A SWT Listener removeHandlers.add(listener);
protected final java.util.Collection	getManagedShellSet() Gets the set of managed shells return The set return shells;
protected org.eclipse.swt.widgets.Event	getSWTEvent(org.eclipse.swt.widgets.Shell shell) Gets a generated SWT Event based on the shell The widget field of the event should be set to the shell param shell A SWT Shell return The event Event e = new Event(); e.widget = shell; e.item = shell; return e;
public final int	getSize() Gets the number of shells the ShellManager manages return The number return shells.size();
public final java.util.Iterator	getWindows() Gets the shells managed by the manager as an Iterator The order in which the shells were added are retained. Note: This method must be invoked by the SWT display thread return The iterator return shells.iterator();
public final boolean	isEmpty() Gets whether the ShellManager manages no shells return True if ShellManager is empty return shells.isEmpty();
protected final void	notifyAddListeners(org.eclipse.swt.widgets.Shell sender) Notifies the WindowAddedListener handlers param sender A SWT shell that "sends" the events Iterator iter = addHandlers.iterator(); for(int i = 0; i < addHandlers.size(); i++) { ((Listener)iter.next()).handleEvent(getSWTEvent(sender)); }
protected final void	notifyRemoveListeners(org.eclipse.swt.widgets.Shell sender) Notifies the WindowRemovedListener handlers param sender A SWT shell that "sends" the events Iterator iter = removeHandlers.iterator(); for(int i = 0; i < removeHandlers.size(); i++) { ((Listener)iter.next()).handleEvent(getSWTEvent(sender)); }
public final void	performForShells(org.eclipse.swt.widgets.Listener command) Invokes the handleEvent method specified by the SWT listener for each managed shell The event's widget is set to the reference of the shell invoking it param command A command implemented as a SWT Listener Iterator iter = shells.iterator(); for(int i = 0; i < shells.size(); i++) { Shell aShell = (Shell)iter.next(); Event evt = new Event(); evt.widget = aShell; evt.data = this; command.handleEvent(evt); }
public final void	removeWindow(org.eclipse.swt.widgets.Shell shell) Removes a shell from the shell manager Note: This method must be invoked by the SWT display thread param shell A SWT Shell shells.remove(shell); notifyRemoveListeners(shell);
public final void	removeWindowAddedListener(org.eclipse.swt.widgets.Listener listener) Removes a listener that will be invoked when a shell has been added to the ShellManager param listener A SWT Listener addHandlers.remove(listener);
public final void	removeWindowRemovedListener(org.eclipse.swt.widgets.Listener listener) Removes a listener that will be invoked when a shell has been removed from the ShellManager param listener A SWT Listener removeHandlers.remove(listener);
public static final org.gudy.azureus2.ui.swt.components.shell.ShellManager	sharedManager() Gets the application's shared shell manager This ShellManager has no bearing on other ShellManager instances Note: This method must be invoked by the SWT display thread return instance = new ShellManager(); return instance;
