Hi,
is there any Listener to add to a viewpart so that, if the user try to close the view, a notification dialog <yes, Abort> will be opened and the user can by clicking ok close the view or by clicking abort not closing it.

Thanks

Try: view.getSite().getWorkbenchWindow().addPerspectiveListener(n ew
IPerspectiveListener2() { ... });
The method on IPerspectiveListener2 gets called before the view or its
controls are disposed, and the id parameter indicates which view is being
closed. Don't forget to remove the listener in your view's dispose method.

It would help to know more about what you're trying to do here. There may
be a cleaner way.


hm. I've lost a machine.. literally _lost_. it responds to ping, it works completely, I just can't figure out where in my apartment it is.

Thanks for your answer, but how can i avoid that the view will be closed. for example when the user click on abort button <dont like to exit the view>.

Thanks.

Well a standard view does not have a close button. Only an a close button if you give it a closable option in the plugin.xml. So if you remove the closable and do not have anny buttons that are couse the view to be closed. then yoru good. But your sounding likeyour talking about an Dialog.

Thanks for the answer,

no it is a view what i have. derived from ViewPart and is closeable. I need it closeable but if the user have not saved the jobs on the view, i must give him a notification and possibility to abort the close.

Thanks.

Some thing more: it is like on eclipse: If you edit a file and you want to close the tab, it comes a dialog to tell you if you want to save changes. its the same scenario for me.

You could extend the view to SavablePart so you can use the Dirty state.

Hi,
thanks for your answers,
i just need now to create my own dialog with yes, no cancel. you know how to do this. i have a dialog here is the code but i doese not work with no button. just ok and cancel works.

here is the code:





/**
* This dialog should used to confirm a message and get decision between yes or no (OK or CANCEL). <br/>
* The title and icon of dialog can (should) to set with a action. Included text should set per separate action.

* @param parentShell Composite, where dialog is extended.
* @param action Set title, icon and a short description of dialog.
*/
private YesNoAbortDialog(Shell parentShell, Action action)
{
super(parentShell, action);
}

/**
* constructor.
*
* @param parentShell Composite, where dialog is extended.
* @param action Set title, icon and a short description of dialog.
*/
private YesNoAbortDialog(Shell parentShell, String dialogTitle, Image dialogTitleImage, String dialogMessage)
{
super(parentShell, dialogTitle, dialogTitleImage, dialogMessage);
}

/**

*/
public static boolean openDialog(final Shell parentShell, final Action action, final String dialogMessage)
{
Validate.notNull(dialogMessage);

inValues = dialogMessage;

return (new YesNoAbortDialog(parentShell, action).open() == IDialogConstants.OK_ID);
}

*/

public static int openDialog(final Shell parentShell, final String dialogMessage)
{
Validate.notNull(dialogMessage);

int code = new YesNoAbortDialog(parentShell, Resources.Frames.Dialog.Texts.CONFIRM_TITLE.getText(),
Resources.Frames.Dialog.Images.CONFIRM_IMAGE.getImage(), dialogMessage).open();

if (code == IDialogConstants.OK_ID)
{
return ISaveablePart2.YES;
}
else if (code == IDialogConstants.NO_ID)
{
return ISaveablePart2.NO;
}
else if (code == IDialogConstants.CANCEL_ID)
{
return ISaveablePart2.CANCEL;
}

else
{
return ISaveablePart2.DEFAULT;
}

}

/**

*/
@Override
protected Control createCustomArea(Composite parent)
{

return control;
}

/**

Hi,

you can implement the ISaveablePart2 [1] interface to open your custom
dialog.
