Hi,
This is an issue that I have also had to
deal with recently.
I had limited success using code similar
to that which you have outlined below. The major problem is that pressing CTRL
+ the majority of keys causes the browser to intercept these key presses and
perform its own actions. Trying ctrl + almost every key on the keyboard
resulted in only getting about 6 or so CTRL + key combinations being made available
to me. Trying ALT + key was even less successful as the flash player just
seemed to loose focus entirely, with the browser menu then being given focus.
Has anybody else had any success with key
board shortcuts? At first glance, it doesn’t seem to be possible to
provide logical keyboard navigation on forms with more than a handful of
controls. Of course, tab navigation is still possible.

Hi,
1) Yeah, you can trap the keyboard events using
ActionScript. You can use
"keyDown" event with Key object tofind
about pressed keys.. See example
code later in the mail.
2) you can use the combination of mouseDown,
mouseMove & mouseUp event to
make dragging happen. Look at Manish's Google map
example, see how he is
dragging...

Hi members,
I am new to Flex
coding. I did learn a lot from coenraets web site
and also from richinternetapps.com. I do really
appreciate them for letting
others to see their code and learn from it.
I do have couple of issues to resolve. I didtry
search on Livedocs and
other websites for solutions but didn't findany.
1) Can any one
programmed hotkeys(keyboard shotcuts) in flex ? for
example, instead of using mouse to click on tab of
TabNavigator container
users can use keyboard shortcuts say Ctrl+T or
Alt+T something like this.
There will be a problem using Alt as accesskey
because Alt key has been used
for windows hotkeys. Please help.
2) My user requires
that they should be able to zoom a scanned image
and then move/drag that image. I did accomplished
zooming part but unable to
drag the image. Here is the mxml file for your
ref.....
<<manageSchedule_3.mxml>>
Thanks in advance.
Thanks!
Hari
