[platform-swt-dev] One problem not able to solve chatura,ravikanth
|
Hi, i did as u told but iam gettin foll error in console:where Testlog is
the class where iam implementing run,init ,selectionchanged methods.
Pls check this out,iam getting psyched by this
Could not create action delegate for id: org.eclipse.login.Testlog
Reason:
Plug-in "org.eclipse.login" was unable to instantiate class
"org.eclipse.login.Testlog".
Could not create action delegate for id: org.eclipse.login.Testlog
Reason:
Plug-in "org.eclipse.login" was unable to instantiate class
"org.eclipse.login.Testlog".
when i run,i get the sample.gif icon with the tool tip and also the menu
item in the workbench Runtime instance.But when i press the icon i get
message as:
" The choosen operation is currently not available"
My Testlog class is like this:
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.*;
import org.eclipse.ui.IWorkbenchWindowActionDelegate;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.viewers.ISelection;
public class Testlog implements IWorkbenchWindowActionDelegate {
private IWorkbenchWindow window;
Display display= new Display();
final Shell sh = new Shell(display);
public void run(IAction action)
{
Logindialog dialog = new Logindialog(sh);
Login login = dialog.open();
MessageBox msg = new MessageBox(sh,SWT.OK);
if(login.getButtonResponse())
{
msg.setMessage("Your id is:"+login.getID()+"\nYour Password is
:"+login.getPassword());
msg.open();
}
while(!sh.isDisposed())
{
if(!display.readAndDispatch())
display.sleep();
}
display.dispose();
}//end of run method
public void selectionChanged(IAction action, ISelection selection)
{
}
public void dispose()
{
}
public void init(IWorkbenchWindow window)
{
this.window = window;
}
}
