FX Projects Types [message #1226833]

I am looking seriously at using Eclipse for JavaFX work. I have little Eclipse experience. What is the best way to create a JavaFX product with an update site?

I assumed I wanted the OSGi e4 Application project (I DO want to use e4 with FX if I take up with Eclipse). Unfortunately, the template project throws exceptions so I don't even get to base zero with this approach.

A plain JavaFX project does not appear to offer e4 capabilities and an update site.

I haven't been able to find out enough information to decide what I need to do to get where I want to go. The sample projects really aren't that informative.

I develop on 64 bit Linux and deploy to both Linux and Windows.

Thanks for any direction which project types I need to use.

Yes you want an "e4 Application project"

What exceptions does it throw? Did you follow the tutorial on how get up
an e4 FX application [1]? Did you add a least a Window in the generated
e4xmi-File?

There's not much documentation specific to e4 on JavaFX because fairly
anything documented for e4 on SWT applies to FX as well.

Both should be fine.

Thanks Tom. I started all over again (from re-install eclipse) and got a project, including update site creation, to work. Can you direct me to documentation on how to use the update site in my nifty new application? I know I've got to include a menu item in my Help menu but I have no idea where to go beyond that. Is there a document you know of that explains how to use an update site? I've done some searching but haven't found any direction yet.

Still searching........testing.........

There's no ready UI for Update-Sites if you are going JavaFX! Generally
speaking what you learn about is p2.

There is very prelimenary code in org.eclipse.fx.core.p2 is able to
check for updates of your product but is has no UI and and haven't
really tested this code either so I can guarantee it works (it was
extracted from an SWT-RCP-Application we are running for a customer so
if I've done everything correct it will work!)

The process should look like:

class UpdateHandler {
@Execute
void update(UpdateService us) {
us.checkUpdate(this::callback);
}

void checkUpdateCallback(UpdateCheckData data) {
if( data.getValue() == Boolean.TRUE ) {
us.update(data, this::updateCompleted);
} else {
Platfrom.runLater(....);
}
}

void updateCompleted(UpdateData data) {
if( data.getValue() == Boolean.TRUE ) {
Platfrom.runLater(....);
} else {
Platfrom.runLater(....);
}
}
}

if you are on Java7 you have to replace the method references through
anonymous classes ;-)

Please note that this only checks for updates for already installed
FEATURES it doesn't all you to install additional software!
