java - Can an Actor handle click and key down events? -


i'm trying make actor handle both click , key down events. initialized actor (in case, image) following:

stage = new stage(); texture = new texture("badlogic.jpg"); image image = new image(texture); image.addlistener(new clicklistener() {     @override     public void clicked(inputevent event, float x, float y) {         gdx.app.log("image clicklistener", "clicked");     }      @override     public boolean keydown(inputevent event, int keycode) {         gdx.app.log("image clicklistener", "keydown. keycode=" + keycode);         return true;     } }); stage.addactor(image); gdx.input.setinputprocessor(stage);

when click on image, clicked event fired expected, i.e., see respective log. however, no matter key press, key down event not fire. question is: why? can't actor able handle both click , key down events?

by default should rather attach keyboard listener stage since stage has keyboard focus on it should like

    stage.addlistener(new inputlistener()      {         @override         public boolean keydown(inputevent event, int keycode)          {             gdx.app.log("image clicklistener", "keydown. keycode=" + keycode);             return true;         }     });

if want change focus on actor can using stage method setkeyboardfocus(actor actor). should like:

    image.addlistener(new clicklistener()      {         @override         public void clicked(inputevent event, float x, float y) {             gdx.app.log("image clicklistener", "clicked");         }          @override         public boolean keydown(inputevent event, int keycode) {             gdx.app.log("image clicklistener", "keydown. keycode=" + keycode);             return true;         }     });      stage.setkeyboardfocus(image);

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
