Eclipse RCP Step by Step

Command Parameter RCP (Eclipse RCP) Open MANIFEST.MF file and right click on the Command and select "commandParameter" from "New". After creating "commandParameter", enter the details, like "id", "name" and make optional as "false". After adding the parameter in the command, in View (or Editor) at the time of calling the command set the parameter. Refer the following code to set the parameter at the time of execution. Code in View (or Editor): 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 ICommandService commandService = ( ICommandService ) getSite (). getService ( ICommandService . class ); IHandlerService handlerService = ( IHandlerService ) getSite (). getService ( IHandlerService . class ); // Enter the ID of the Command as the argument to getCommand() method in next line. Command sysoComm = commandService . getCommand ( "Re...

Execute Command from View/Editor in Eclipse RCP All Commands will be registered to IHandlerService. If we get the IHandlerService instance then we can call the desired command and then execute it. // Get the Instance of IHandlerService from View // Alternate way of getting site object is this also: // PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActivePart().getSite() // But we prefer  following so we get the appropriate IWorkbenchPartSite object. IHandlerService service = (IHandlerService) getSite().getService(IHandlerService.class);  try { service.executeCommand("ResumeParser.commands.sampleCommand", null);  } catch (ExecutionException e1) {  e1.printStackTrace();  } catch (NotDefinedException e1) {  e1.printStackTrace();  } catch (NotEnabledException e1) {  e1.printStackTrace();  } catch (NotHandledException e1) {  e1.printStackTrace();  }

Fie Dialog and Folder Dialog in Eclipse RCP File Dialog in Eclipse: - This will only allow you to select the files in the Dialog Box FileDialog fileDialog = new FileDialog(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell()); // Following line is Optional if you want to, enable filter for specific files. //fileDialog.setFilterExtensions(new String[] {"*.txt","*.csv"}); String filePath = fileDialog.open(); System.out.println(filePath); Folder Dialog in Eclipse: - This will allow you to select the folder in the Dialog box. DirectoryDialog directoryDialog = new DirectoryDialog(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell()); // Optional - if you want to open specific path //directoryDialog.setFilterPath("/home/hv185014/junk/"); String directoryPath = directoryDialog.open(); System.out.println(directoryPath);

Builder Design Pattern - Java When the construction of the class contains a large number of argument then this Design Pattern is preferred. Builder Pattern, as the name suggest, it helps to reduce the complexity in Building Java Object. public class Person { private String firstname; private String lastname; private String address; private int age; private String city; private String state; public Person(String firstname, String lastname, String address, int age, String city, String state) { super(); this.firstname = firstname; this.lastname = lastname; this.address = address; this.age = age; this.city = city; this.state = state; } } In the above example, you can see, that the construction of the Person class has 6 arguments and few of them can be optional. So we can create a new PersonBuilder class which will help to create the Object of the Person class. public class PersonBuilder { private String firstname; ...

Open Eclipse RCP application as maximized Open File : ApplicationWorkbenchWindowAdvisor.java in you RCP application and override the method "postWindowOpen()" and write the code as mentioned below : @Override public void postWindowOpen() { super.postWindowOpen(); IWorkbenchWindowConfigurer configurer = getWindowConfigurer(); configurer.getWindow().getShell().setMaximized( true ); } Following Books are good to refer :

Show Perspective switch bar in Eclipse RCP application Open file ApplicationWorkbenchWindowAdvisor.java in your plug-in project. Override the method, preWindowOpen and as shown below, setShowPerspectiveBar as True. @Override public void preWindowOpen () { IWorkbenchWindowConfigurer configurer = getWindowConfigurer(); configurer.setShowPerspectiveBar( true ); } Run your RCP application, and on Right side top, you will be able to see perspective Switch. Following Books are good to refer :

Create (pulldown) Menu in Toolbar Step 1. Create Toolbar with PullDown Step 2. Create MenuContribution  Step 3. Add items to MenuContribution Step 4. Run the application Step 1. Create Toolbar with PullDown Create your Eclipse RCP application ( with mail template). Suppose open command id is "HarikrushnaVToolbar.open" then create a toolbar with command in it,  as shown below: now, convert the style to "pulldown". Now, if you run the application, you will see a pulldown button next to toolbar icon as follow : Step 2: Create MenuContribution Now, create a MenuContribution, which will define the items for pulldown menu. Define, locationURI to the same name as the menu:commandId , here we provide the LocationURI as "menu:HarikrushnaVToolbar.open" Also Define Class name as "AllMenuItems". Step 3. Add items to MenuContribution Click on " class ", you will see the...
