Hi,
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.
Is there a way to tell the browser or OS to let the event through?
For example, on an AdvancedDataGrid I have set the keyUp event to
handleCaseListKeyUp(event), which calls the following function:
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);
}
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:
charCode: 0
char:
keyCode: 17
ctrlKey: false
altKey: false
shiftKey: false
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.
Has anyone successfully implemented standard copy and paste keyboard
handling?
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?
Or do I need to create the listener manually at a higher level and
pass the event down into my modular application's guts?
Thanks in advance for any help.
Ian
