POCapturing Cmd-C (or Ctrl-C) keyboard event from modular Flex application in browser or AIR
text
Body
copied!<p>It seems that it is impossible to capture the keyboard event normally used for copy when running a Flex application in the browser or as an AIR app, presumably because the browser or OS is intercepting it first.</p> <p>Is there a way to tell the browser or OS to let the event through?</p> <p>For example, on an AdvancedDataGrid I have set the keyUp event to handleCaseListKeyUp(event), which calls the following function:</p> <pre><code> private function handleCaseListKeyUp(event:KeyboardEvent):void { var char:String = String.fromCharCode(event.charCode).toUpperCase(); if (event.ctrlKey && char == "C") { trace("Ctrl-C"); copyCasesToClipboard(); return; } if (!event.ctrlKey && char == "C") { trace("C"); copyCasesToClipboard(); return; } // Didn't match event to capture, just drop out. trace("charCode: " + event.charCode); trace("char: " + char); trace("keyCode: " + event.keyCode); trace("ctrlKey: " + event.ctrlKey); trace("altKey: " + event.altKey); trace("shiftKey: " + event.shiftKey); } </code></pre> <p>When run, I can never get the release of the "C" key while also pressing the command key (which shows up as KeyboardEvent.ctrlKey). I get the following trace results:</p> <pre><code>charCode: 0 char: keyCode: 17 ctrlKey: false altKey: false shiftKey: false </code></pre> <p>As you can see, the only event I can capture is the release of the command key, the release of the "C" key while holding the command key isn't even sent.</p> <p>Has anyone successfully implemented standard copy and paste keyboard handling?</p> <p>Am I destined to just use the "C" key on it's own (as shown in the code example) or make a copy button available?</p> <p>Or do I need to create the listener manually at a higher level and pass the event down into my modular application's guts?</p>
