Exit dialog window

[TheProjectDark]

Description

I was reviewing code in NetBeans and often miss-clicked cmd+q instead of pressing cmd+a, and it was so annoying to wait until the IDE re-launches so I just implemented exit dialog window like in Firefox or JetBrains.

Implementation

The exit flow is centralized in ExitDialog.showDialog(), which is already called during shutdown. It checks for open unsaved files first: if there are any, NetBeans shows its existing save/discard dialog. If there are none, it checks the new preference and, when enabled, shows Exit, Save All and Exit, and Cancel. Choosing Save All calls LifecycleManager.saveAll() before allowing shutdown; Cancel keeps the IDE open.
The checkbox is in Tools > Options > General. The panel loads its value when the options page opens, detects changes so Apply is enabled when appropriate, and saves the preference when settings are applied. The preference is stored with NetBeans’ user settings and defaults to enabled. Cmd+Q and Ctrl+F4 reach the same shutdown flow through their respective platform handlers/keymap bindings.

Thanks for looking at this. I hit this issue sometimes with a dual monitor setup when the close icon is right next to something I'm trying to click on the other screen! 😄

Couple of changes that are not related need looking at, and I'm not sure why we need the Save All option?

[neilcsmith-net]

Let's leave the word "NetBeans" out of these and keep the messages generic. Less surprising for platform applications, and we can always brand them later in the nb cluster if need be.

Changed to IDE

[neilcsmith-net]

I had considered something even more generic than "IDE" (eg. ".. application" or just "Do you want to exit?") given that not all platform applications are IDEs. Although, as mine is, I won't complain too much if other people are happy with that? 😄

[TheProjectDark]

So far I implemented the requested changes

[neilcsmith-net]

Thanks. Principle looks good to me, but not tested yet. Triggered CI and a dev build. Will wait for feedback from others.

Everything will need squashing into a single commit and force pushing before it could be merged. But hold fire on that in case there's other feedback first.

LGTM to me.

Author in commit expect 2 parts.

tested a scenario which would open both exit popups in sequence.

run project with

    static void main() throws InterruptedException {
        System.out.println("sleeping");
        Thread.sleep(Duration.ofMinutes(2));
    }

try to exit IDE.

new popup:

old popup:

this worked, but the visually confusing aspect is that it looks like the new dialog has the cancel button selected, but focus is on exit. Probably would have to play with the NotifyDescriptor config a bit to make both visually consistent. (the old dialog will select a list item on enter - which isn't great either tbh)

[neilcsmith-net]

@mbien how did you test that scenario with the new vs old popup? Using ant tryme with netbeans.full.hack?

This scenario might be a little more complicated to get right. We have the various @OnStop registered Callable that might show a dialog, like the one you bring up. These are called after the ExitDialog. Ideally we want anything that's trapping exit to only show if no other dialog has intervened first. And I'm not sure we have a good way to do that at the moment.

The dialog is also showing up strangely for me at times, not like the screenshot, but with the buttons vertically stacked to the right of the label. That might be issues we sometimes see with chaining multiple dialogs in the EDT.

Sorry, @TheProjectDark now we've got to testing this we might be facing more edge cases than envisaged. I would still like us to get this feature in if we can work out how.

[neilcsmith-net]

Yes, there's definitely something weird with the look of the last push on my system -

I would suggest reverting to your previous iteration, but with exit as the default value. eg.

            Object exit = bundle.getString("CTL_ExitConfirmationExit");
            Object cancel = bundle.getString("CTL_ExitConfirmationCancel");
            NotifyDescriptor descriptor = new NotifyDescriptor(
                    bundle.getString("MSG_ExitConfirmation"),
                    bundle.getString("TTL_ExitConfirmation"),
                    NotifyDescriptor.YES_NO_OPTION,
                    NotifyDescriptor.QUESTION_MESSAGE,
                    new Object[] { exit, cancel },
                    exit);
            Object choice = DialogDisplayer.getDefault().notify(descriptor);
            return exit.equals(choice);

Having Cancel as default works strangely - it's highlighted but pressing Enter still exits (as it should). This feels like a disconnect between keyboard usage of Enter and Escape, and what you can see on screen.

I think it might be better to default to disabled for the coming release as well. We can consider enabling by default at a later date.

Had a look through other registered @OnStop handlers and not sure there's any but the running tasks one that will also show. Having both in that scenario is probably OK.

Thanks for the comments! I tried to fix it and that's what I did:

What changed (ExitDialog.java, the confirmation branch only)

• The dialog now uses a DialogDescriptor with a small custom body: the question icon with the message, and a row with two real JButtons (with mnemonics, as in the save dialog).
• Exit is the root pane's default button (Enter) and also gets the focus when the window opens.
• The button order is fixed: Exit on the left, Cancel on the right, aligned to the right edge.
• Esc and the window close button only close the dialog, they never exit the IDE.
• The dialog has a minimum width so the buttons are placed under the text.
