Another way a TopComponent can be context sensitive is in the requirement that the menubar and toolbar need to relate to a specific TopComponent. Below you see that when Win1 is active, a different group of menus and toolbars is available... ... than when Win2 is active: Part of the solution to this is described here recently about multiple rows of toolbars. However, this only addresses the topic of toolbars. What about menubars? And maybe other components too? I.e., when a...

I picked up a cool idea from a Polish developer, Dominik Cebula, recently. In the same way that the NetBeans Platform has context sensitive Actions, there should be context sensitive TopComponents. Only if an Object of a specific type specified in the public constructor of the TopComponent is found in the Lookup should it be possible to open the TopComponent. And then the Object is available to the TopComponent, without the TopComponent needing to implement a LookupListener. For...

The user starts the application. The splash screen is shown. Right after the modules are loaded, as indicated by the text in the splash screen, a small login screen appears. The user fills in the wrong login credentials and clicks OK. The text in the splash screen shows that one or more modules are being turned off. Then the main window of the application appears. Because the login credentials were wrong, one or more of the modules have been disabled.  import java.util.List;imp...

Realized today that toolbars can be placed in different rows: The above is a result of a file I named "All.xml" that has this content and is found in the same package as the layer.xml file: <?xml version="1.0"?><!DOCTYPE Configuration PUBLIC "-//NetBeans IDE//DTD toolbar//EN" "http://www.netbeans.org/dtds/toolbar.dtd"><Configuration> <Row> <Toolbar name="File" /> </Row> <Row> <Toolbar name="UndoRedo" /> <Toolbar name="Clipboard"/> </Row> ...

Handy, need to explore this further. import javax.swing.AbstractButton;import javax.swing.Action;import javax.swing.JMenuItem;import org.openide.awt.Actions;import org.openide.awt.Actions.ButtonActionConnector;import org.openide.util.lookup.ServiceProvider;@ServiceProvider( service = ButtonActionConnector.class, position = 100)public class MyButtonActionConnector implements ButtonActionConnector { @Override public boolean connect(AbstractButton button,...

Following from the above, here's how to add a new tab in the Java Editor, on the fly (as described here, possible from 8.0 onwards), i.e., when the "Design Custom Component" menu item (which is only available when you right-click a subclass of com.vaadin.ui.CustomComponent, as described yesterday) is clicked: @Overridepublic void actionPerformed(ActionEvent ev) { dobj.getLookup().lookup(Openable.class).open(); TopComponent activated =...

Climb up the hierarchy (thanks to this) to determine whether a class is a subclass of com.vaadin.ui.CustomComponent and, if so, enable and display a popup menu on it so that it can be opened in a visual designer of some kind. @ActionID( category = "Tools", id = "org.tc.customizer.DesignCustomComponentAction")@ActionRegistration( displayName = "#CTL_DesignCustomComponentAction", lazy = false)@ActionReferences({ @ActionReference(path =...
