Hi,
I am using RCP. In my application i use the eclipse console to display message to the user.
Issue : the messages does not get print at runtime. Instead it prints after the execution of the UI thread.
My console code is as below,
public class ConsoleDisplayMgr
{
private static ConsoleDisplayMgr fDefault = null;
private String fTitle = null;
private MessageConsole fMessageConsole = null;
public static final int MSG_INFORMATION = 1;
public static final int MSG_ERROR = 2;
public static final int MSG_WARNING = 3;
public ConsoleDisplayMgr(String messageTitle)
{
fDefault = this;
this.fTitle = messageTitle;
}
public static ConsoleDisplayMgr getDefault() {
return fDefault;
}
/**
*
* @param msg
* @param msgKind
*/
public void println(String msg, int msgKind)
{
if (msg == null) return;
if (!displayConsoleView())
{
MessageDialog.openError(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(), "Error", msg);
return;
}
getNewMessageConsoleStream(msgKind).println(msg);
}
/**
*
*/
public void clear()
{
IDocument document = getMessageConsole().getDocument();
if (document != null)
document.set("");
}
/**
*
* @return
*/
private boolean displayConsoleView()
{
try
{
IWorkbenchWindow activeWorkbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (activeWorkbenchWindow != null)
{
IWorkbenchPage activePage = activeWorkbenchWindow.getActivePage();
if (activePage != null) {
activePage.showView("org.eclipse.ui.console.ConsoleView", null, 2);
}
}
}
catch (PartInitException localPartInitException)
{
return false;
}
return true;
}
/**
*
* @param msgKind
* @return
*/
private MessageConsoleStream getNewMessageConsoleStream(int msgKind)
{
int swtColorId = 6;
switch (msgKind)
{
case 1:
swtColorId = 6;
break;
case 2:
swtColorId = 12;
break;
case 3:
swtColorId = 10;
}
MessageConsoleStream msgConsoleStream = getMessageConsole().newMessageStream();
msgConsoleStream.setColor(Display.getCurrent().getSystemColor(swtColorId));
return msgConsoleStream;
}
/**
*
* @return
*/
private MessageConsole getMessageConsole()
{
if (this.fMessageConsole == null) {
createMessageConsoleStream(this.fTitle);
}
return this.fMessageConsole;
}
/**
*
* @param title
*/
private void createMessageConsoleStream(String title)
{
this.fMessageConsole = new MessageConsole(title, null);
ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[] { this.fMessageConsole });
}
}
------------------------------------------------------
Is there a way to print the messages in runtime ?
Thanks

Hi,
There is in principle no problem to log in run-time.
Example:
In the start method of your plugin activator, add:
ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[] { new MyConsole() });
with:
public class MyConsole extends MessageConsole {
public ScriptConsole() {
super("my Console", Acivator.getDefault().getImageDescriptor("icons/myIcon.gif"));
MessageConsoleStream outMessageStream = newMessageStream();
MessageConsoleStream errMessageStream = newMessageStream();
if (!GraphicsEnvironment.isHeadless()) {
errMessageStream.setColor(Display.getCurrent().getSystemColor(SWT.COLOR_RED));
}
System.setOut(new PrintStream(outMessageStream));
System.setErr(new PrintStream(errMessageStream));
}
}
All outputs made either by System.out.println() or System.err.println() or by the Eclipse logging framework, eg.: Activator.getLogger().log(new Status(IStatus.WARNING, Activator.PLUGIN_ID, "myMessage") should go to your console.
Hope that helps,
Bernard.
