application.onExit()?

[krauss]

Here's one for the list...

It would be very nice to have an application.onExit() method that one could call to perform end-of-session housekeeping duties such as last-minute error-checking, orphan record clenaup, etc.

Under Solution settings you allready have an osulitionclose method.

I'm aware of the onSolutionClose(), but what I'm worried about is users who don't shut down cleanly.

What would be ideal is a method that captures the clicking of the main window close box in the same way that, for example, onDelete events can be captured from a form.

The method that you attach in solution settings as "on close method" does exactly what you want: capture the clicking of the main window close box (and other ways of exiting the solution, of course).

If you attach a method onSolutionClose you can prevent the user from exiting, asking him for example if he really wants to shutdown the app. Just do something like

Code: Select all

var button = plugins.dialogs.showQuestionDialog( '',  'Really quit?',  'Yes', 'No');
if (button == 'No')
{
   return false;
}

The only thing you cannot do (I believe) is distinguish between various ways of exiting the solution (close box/Menu/Method)...

Thanks, Patrick! That is exactly what I was looking for.

I was unable to find this in the documentation; if it's not that my eyes (and brain) are going bad, perhaps this detail could be added?

Krauss,

The information you are looking for can be found in the Servoy Developer
Edition Volume 1: User's Guide, Chapter 17, "Settings", in section
17.2 "Solution settings", subsection 17.2.4 "Choosing a method to close
your solution", page 549.

If you do not yet have the printed documentation, you can also use the
online Servoy Help Navigator:
-Choose Help>Help (F1).
-Select the "Search" tab.
-Enter "onClose", "solution", or "setting" in the search box.
-Double click on the "Solution settings" topic in the Topic List.

Once the topic is open, you can go directly to the area you are interested in:
-Choose Tools>Find.
-Enter one or more characters in the "Find What" box.
-Press "Find Next" to highlight the first instance of your search criteria.
-Press "Find Next" for each addtional instance of your search criteria.

NOTE: Make sure that you have a topic open BEFORE you choose Tools>Find.

Not to quibble, but the information I was looking for isn't actually in the documentation. The section to which you refer (and which I'd already looked at when I made my first post on the topic) is composed of a screen shot and the following text:

Choosing a method to close your solution
You can run a Servoy method (script) just before your solution closes. The On close method setting is blank or "<none>" by default when a new solution is created.
To select an on close method:
*Choose File > Solution Settings.
* Select the method you want to run from the On close method pull-down list (or select <none>).

That's it.

It doesn't say that the on close method captures the event when someone clicks on the main close box. That's the condition I'm concerned about, and that's what I'm suggesting be added to the documentation.

Krauss,

We appreciate your detailed input and will modify the description of the
onClose method solution setting in the documentation to include this option.

The Solution setting onClose method is a good workaround, but I think the application.onExit() is still useful.

I have an application that has several modules. Already about 12 modules, but this will be more in the near future.
Now I have to put in all these solutions a call to a method that I want to run when the application closes (I need to check if the database is in a transaction and if it is, I'll do a rollback)

I would be easier if I could run this script from an application.onExit to avoid that some of the submodules doesn't have the onClose method filled.
