java - Platform specific cut paste mnemonics swing. -


i'm developing own text-like jcomponent. isn't subclass of jtextcomponent, because isn't using document model. i'd still support standard mnemonics of cut/copy/paste, know keystrokes depend on platform.

ultimately, i'll let user edit keybindings themselves, now, i'd @ least default sensible.

is possible lookandfeel somehow? or need detect platform myself , have mapping per platform?

i'm using java 8 if makes difference.

there no laf property i'm aware of purpose.

however might able use information inputmap of laf. following works windows 8:

import java.awt.*; import javax.swing.*;  public class platformmnemonics {     public static void main(string[] args)     {         keystroke copykeystroke = null;         keystroke cutkeystroke = null;         keystroke pastekeystroke = null;          inputmap im = (inputmap) uimanager.get("textfield.focusinputmap");          (keystroke keystroke: im.keys())         {             boolean uppercase = character.isuppercase( keystroke.getkeycode() );              if ( uppercase )             {                 string actionmapkey = im.get( keystroke ).tostring();                  if ("copy-to-clipboard".equals(actionmapkey))                     copykeystroke = keystroke;                 else if ("cut-to-clipboard".equals(actionmapkey))                     cutkeystroke = keystroke;                 else if ("paste-from-clipboard".equals(actionmapkey))                     pastekeystroke = keystroke;              }         }          system.out.println("copy  keystroke: " + copykeystroke);         system.out.println("cut   keystroke: " + cutkeystroke);         system.out.println("paste keystroke: " + pastekeystroke);     } }

note there 3 bindings on windows each action can see in key bindings programs displays key bindings every swing component. displayed binding think interested in.

javascript - cocos2d-js draw circle not instantly -

i wondering how draw circles (or other shapes also) not instantly. so far tried drawcircle(args...) in ccdrawnode.js , drawcircle(args...) in cc.drawingprimitivecanvas class, , draw circles popping out instantly on screen. what if want achieve effect circular progressive bar, completes circle based on percentage of initialization? or more generally, if want draw circle respect prolonged period? thinking there drawcircle function elapsed time argument fail find any. or have implement own? thanks suggestions, far out of ideas. i think have implement own. think can achieve update circle drawing on each time update() function called.
