Re: [Jmol-users] Jmol Keyboard Interaction
Thanks for the input everyone. The keyboard input will control jmol/jsmol but also do other things, but I do like using arrow keys to rotate the structure, for example. Other features can be added later to allow jmol to more easily *modify* rather than merely view structures. It's hard to imagine these features without a fuller keyboard interface (features similar to the structure-editing capabilities of avogadro or materials studio). The javascript version already works perfectly, as keyed events are captured by the website (even if jsmol previously has focus) and I'm just using javascript to do whatever I want to do (including interacting with jsmol via JmolScript calls). For the java version, the best I've been able to do is: use a function which restores focus to the website (so they keyboard commands aren't trapped by jmol) whenever 1) a script is executed by jmol using ScriptCallback or 2) the users mouse leaves the jmol div (using a standard mouseout event in the DOM). This means the user doesn't have to "click" off of jmol to restore focus and re-enable the keyboard interactions. It doesn't help if the user, for example, uses the mouse to rotate the structure and leaves the mouse on jmol the entire time. In that instance, jmolnever loses focus and so the keyboard events aren't passed to the website. I could use the callbacks more aggressively, for example by using pickcallback and hovercallback -- but those are uncommon cases -- what I really need is something more encompassing like a "MouseUpCallback" so that any time the clicks on jmol I can redirect focus back to the website. Unfortunately, that callback doesn't exist in the jmol scripting environment. It's hard to know how much any of us should invest in these java-specific issues given the aggressive nature of browsers toward javascript -- but my website really serves my research group, not the general public, and there I can certainly get the users to install Waterfox+JAVA.

It looks like the example would only work for the Javascript version. Or
could it also work for the Java version (with some adjustment)?

Re: [Jmol-users] Jmol Keyboard Interaction
David,
OK, so the beauty of this system is that you can implement any sort of
additional functionality you want using readily available methods that have
nothing to do with Jmol or JSmol. It's one of the bonuses of working in
JavaScript and jQuery.
So, for example, if you want to implement a key listener that implements +
and - to actuate zooming, you can do it this way:
c = $("#jmolApplet0_canvas2d")
c.attr("tabindex", 1)
c.mouseover(function(){c.focus()})
c.keypress(function(e){
if (e.key == "+")Jmol.script(jmolApplet0, "zoom *1.2")
else if (e.key == "-")Jmol.script(jmolApplet0, "zoom /1.2")
})
Notice that to accept key events, we must (a) provide a tabindex to the
canvas and (b) make sure the canvas has focus when we are looking for key
events.
I would only say that hidden specialized features like this, though
potentially useful, are not necessarily recommended.
Bob

Re: [Jmol-users] Jmol Keyboard Interaction
Have you checked Jmol's "navigation mode" ? As far as I remember, it used the keyboard.

Especially because mouse control of Jmol-Java on MacOS became problematic in browsers. For example could '+/-' for zoom in/out be very handy. The zoom "slider" near the right applet border is quite inconvenient. And the only mouse binding that does work is on the left mouse button without any modifiers. So keyboard commands for translation and Z-rotation could also be very helpful.

Re: [Jmol-users] Jmol Keyboard Interaction
So the "allowkeystrokes" feature simply lets you send commands to the console? No, that's not useful for me -- I'm sure someone has tried to implement navigation-by-keyboard on their jmol-including website before.
