In my Eclipse / RCP application the .metadata directory was always created in the working directory. This worked fine when I was opening the application normally. However, I needed file associations, so the user can just double click on file somewhere on his computer and open the file. If you do this, the working directory …
After updating my RCP application from Eclipse 3.7 to Eclipse 4.x the toolbar always showed the quick access toolbar: How to get rid of that? The workaround is to hide the item with some CSS code.

Some methods want an InputStream, converting a String into an InputStream is very easy: /** * Converts a string into an inputstream * @param s * @return */ private InputStream convertStringToInputStream(String s) { ByteArrayInputStream in = new ByteArrayInputStream(s.getBytes()); return in; }

A small class for easy logging in RCP applications by using the Activators logging functions. This class mainly wraps the need of creating an IStatus object each time we want to log something. import org.eclipse.core.runtime.IStatus; import org.eclipse.core.runtime.Status; public class LoggerUtil { public static void info(String message){ IStatus status = new Status(IStatus.INFO,Activator.PLUGIN_ID, message); Activator.getDefault().getLog().log(status); } public …
A small snippet which switches to a certain perspective via code: IPerspectiveDescriptor[] perspectives = PlatformUI.getWorkbench().getPerspectiveRegistry().getPerspectives(); IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage(); if(page != null) { for (IPerspectiveDescriptor des : perspectives) { if (des.getId().equals("my.perspective.id")) { page.setPerspective(des); break; } } } return null;
In my RCP application some unwanted sections in the preferences showed up: How to get rid of them? Thats easy, in the "ApplicationWorkbenchAdvisor" class, override the "postStartup" method: @Override public void postStartup(){ PreferenceManager pm = PlatformUI.getWorkbench().getPreferenceManager(); pm.remove("org.eclipse.help.ui.browsersPreferencePage"); //$NON-NLS-1$ pm.remove("org.eclipse.help.ui.contentPreferencePage"); //$NON-NLS-1$ } What if you don’t know the id of the preference page? No problem, you …
