Re: How to capture function keys ?
My conclusion: Non-colliding functionkey detection can be done (find keycodes per browser in tables or by manual experimentation). Colliding functionkey detection should be possible using browser plugins. No existing W3 spec for DOM events. For now: least work/max browser support, use the GWT supplied keycode constants, convince the end-users they can use other keys, instead of functionkeys. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to capture function keys ?
Nice idea. I think the new "development mode" a.k.a. "hosted mode", is implemented using plugins, so it might possibly be in the sourcetree in a not too distant future. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to capture function keys ?
i'm not 100% sure how this works, but will throw it out there in case somebody knows or can figure it out. the idea of a hot key was floated for my web app. on a forum a guy offered to create browser plugins for my app that would be able to capture function keys. here's some of the info he sent: "For the suggestion of having a hotkey... if you expose a function to do this in the pages javascript I can create Opera, FireFox, and IE plugins for the site to provide this functionality." "The principal works this way though, just as you embed a flash player/ movie into a website. You’d, for example, have this code embedded: And voila! The plugin is now integrated with that page! So with the plugin now embedded, I could expose some functions for you to set what hotkeys are associated to JavaScript functions. So for example you’d then have this code: var plugin = document.getElementById(‘appname-hotkey’); plugin.setHotKey(“F5”, “nextStep”); plugin.setHotKey(“F4”, “prevStep”); That way whenever F4 or F5 are hit by themselves, they will go to the next step and previous step respectively. This could integrate with your back-end by allowing users to set their hot key preferences when they login. The other perk is that you can easily embed detection if the plugin is loaded, and if it isn’t do nothing. That way if the plugin isn’t installed the page will behave as normal." Anybody know anything about creating browser plugins? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to capture function keys ?
I think that it is not possible to use KeyCodes which are used by the Browser. The root-instance which handles KeyCodes is the Browser, this is the application which controls everything you can see. When the Browser has hardcoded that F5 is for reloading the content, so you can't use this Key with JavaScript. The Browser will not sink this Key-Event to the content. > Is the conclusion that KeyCodes vary between browsers and are therefor > not support in GWT ? Yes it is.

Re: How to capture function keys ?
Thanks for the reply. I did not read the supplied links, but I have read a number of messages in this newsgroup regarding tricky keycodes, however I have not seen a conclusion drawn from this. Is the conclusion that KeyCodes vary between browsers and are therefor not support in GWT ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to capture function keys ?
F1..F12 will probably return values of 112..123. But overall,
JavaScript key events are...interesting. Read this warning as "here
there be dragons":
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/event/dom/client/KeyEvent.html
"Base class for Key events. The native keyboard events are somewhat a
mess (http://www.quirksmode.org/js/keys.html), we do some trivial
normalization here, but do not attempt any complex patching, so user
be warned."
PPK is a good starting point:
http://www.quirksmode.org/js/keys.html
And this article+test script are also excellent:

How to capture function keys ?
I can't find function keys (F1 - F12) in KeyCodes.*
Instead of:
NativePreviewHandler handler = new NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent
event) {
if (event.getTypeInt() == Event.KEY_DOWN) {
}
}
};
Event.addNativePreviewHandler(handler);
I would like to say:
if (event.getTypeInt() == Event.F12) {
}
Am I missing something obvious, or is this not possible ?
