KeyDown keyPressed Problem

I made a little test movie where I placed the below two
scripts, one in a movie script, and the other in a frame script.
The keyDown function in the movie script was accessible all of the
time, and the other script was only accessible while the play head
was on that frame. This is the behavior I expected.
In a larger movie (more frames, scripts, stuff…) this
is not working. The frame script successfully captures the space
bar press, however the function in the movie script doesn’t
ever fire. This is not the behavior I am looking for.
Any reason why the keyDown script in a movie script
wouldn’t fire?

The keydownScript allows keyboard activity to be detected at
a global level. Say
you have a keyDown event tied to a sprite, if you tested the
movie and the Stage
was not the active Window (say the Score was), then the
keyDown event would not
be recognised. So, in your case, it may have been in the one
test, one Director
window was active, in the second situation, a different
window was active.

KeyPressed problem on old phones

Hi friends!
I have a big problem.
I use a Canvas, and it has a keyPressed method... This method works perfectly on my SE K800i, but on my brother's SE K700i this method doesn't work... On SE K750i doesn't work, too. I don't know, what do I have to do... Please help me!
(Sorry for my bad english.)

Here is my "KeyCodeTester" application's source code:

    public void destroyApp(boolean unconditional) {
    class KeyCodeCanvas extends Canvas{
        int kCode = 0;
        int kGameAction = 0;
        String kName = "";
        Font font = Font.getFont(Font.FACE_SYSTEM, Font.STYLE_PLAIN, Font.SIZE_MEDIUM);

HTML5 UI is unable to correctly get the information of key-events .

I have developed a plug-in for Illustrator CC2014.
But, The Plug-in UI which was built with HTML5, is unable to correctly get the information of key-events .
As problems following.
 0-9 key press ： "keyCode" is "0"
 Shift key press ： "shiftKey"is "false"
 Alt key press ： "altKey"is"false"
Even if acquired at any timing（keydown, keypress, keyup） symptom occurs.
In the Windows, you can get the information of key-events is correct at the same implementation.
In the case of the browser UI, even in the Mac, I can correctly get.
What causes that can not be acquired key event information is correct on the plug-in?
Also, If you have any way to get the information of key-events correctly, please let me know.

"in the Mac, the keyevent information was originally can be get"
What does that mean?
"The problem is that the keyevent information was not the correct information."
The problem seems to be that the event contains no information, keyCode is always zero and shiftKey and altkey are always false.
What happens if you try
function onKeydownEvent(obj) {
var keyCode = (obj.keyCode >= 96 && obj.keyCode <= 105) ? obj.keyCode - 48 : obj.keyCode;
var inputStr = String.fromCharCode(keyCode);

How can I get around Javascipt issue with keyboard events?

Javascript issue: keydown, keypress, keyup events cause quick search to initiate with the division key on the keypad and slash key on the keyboard. I am trying to program a graphic representation of a 10 key pad and the division (/) sign is problematic for roll over and processing based on key events. How can I get around this? further notes: Safari also has problems with key events and the division key(s) but no search function connected. Thankyou for time and attention

RemoteApp receives multiple KeyUp events without any keys being pressed

Hi All,
I have a very simple winforms app that I am using to try and track down what is happening with keyboard events when using RemoteApp.
Basically I have a form and a textbox that track the KeyDown, KeyPress and KeyUp events.
As soon as I start my app via RemoteApp I receive multiple KeyUp events without even pressing a key.
Does anyone know why RemoteApp would be sending these random KeyUp events.
The code of my simple test app is as follows:
Public Class Form1
Dim lst As New List(Of String)
Private Sub AddtoList(str As String)
lst.Add(str)
End Sub
Private Sub TextBox1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
AddtoList("txt KeyDown" & vbTab & "KeyCode is " & e.KeyCode)
End Sub
Private Sub TextBox1_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
AddtoList("txt KeyPress" & vbTab & "KeyChar is " & e.KeyChar)
End Sub
Private Sub TextBox1_KeyUp(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
AddtoList("txt KeyUp" & vbTab & "KeyCode is " & e.KeyCode)
End Sub
Private Sub Form1_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
AddtoList("Form Closing")
IO.File.AppendAllLines(Application.StartupPath & "\SimpleKeyUp_v2.txt", lst)
End Sub
Private Sub Form1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
AddtoList("Form KeyDown" & vbTab & "KeyCode is " & e.KeyCode)
End Sub
Private Sub Form1_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
AddtoList("Form KeyPress" & vbTab & "KeyChar is " & e.KeyChar)
End Sub
Private Sub Form1_KeyUp(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp
AddtoList("Form KeyUp" & vbTab & "KeyCode is " & e.KeyCode)
End Sub
Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load
AddtoList("Form Load")
End Sub
End Class
Simply opening and closing the app via RemoteApp gives the following results:
Form Load
Form KeyUp KeyCode is 9
txt KeyUp KeyCode is 9
Form KeyUp KeyCode is 16
txt KeyUp KeyCode is 16
Form KeyUp KeyCode is 16
txt KeyUp KeyCode is 16
Form KeyUp KeyCode is 17
txt KeyUp KeyCode is 17
Form KeyUp KeyCode is 17
txt KeyUp KeyCode is 17
Form KeyUp KeyCode is 9
txt KeyUp KeyCode is 9
Form KeyUp KeyCode is 18
txt KeyUp KeyCode is 18
Form KeyUp KeyCode is 9
txt KeyUp KeyCode is 9
Form KeyUp KeyCode is 18
txt KeyUp KeyCode is 18
Form KeyUp KeyCode is 9
txt KeyUp KeyCode is 9
Form Closing
Cheers and Thanks in Advance!

F:ajax event value binding not working

I'm trying to create an inputText composite component that generates a label, inputText and message with optional ajax capability.
When I attempt to expose the f:ajax event property to page authors, I get the following exception:
javax.faces.view.facelets.TagException: /resources/jimo/textEntry.xhtml @89,50 <f:ajax> '#{cc.attrs.ajaxEvent}' is not a supported event for HtmlInputText. Please specify one of these supported event names: blur, change, click, [etc...]
The javadoc for f:ajax shows the event attribute as type javax.el.ValueExpression, but it doesn't seem that it's being evaluated as such. I'm able to expose the disabled attribute, and it's working as expected.
Any feedback would be appreciated.

Bluetooth keyboard and mouse failures

I have brand new PowerBook G4 15" with Bluetooth. I also have brand new Bluetooth wireless Apple keyboard and mouse. I am running 10.4.5. The keyboard and mouse lose contact with the computer on a regular basis, even though they are right next to each other. Sometimes I get the error sign on the computer, sometimes not. Batteries are fresh. Reboot fixes problem. Apple tech support says "interference" might be problem, but I don't have anything nearby except Linksys wireless router. Any ideas?
PowerBook G4 Mac OS X (10.4.5)
PowerBook G4 Mac OS X (10.4.4)
PowerBook G4 Mac OS X (10.4.5)

Over the weekend my BT apple keyboard has been doing multiple strange things as well.
First, the batteries died, something that, of course, happens from time to time. Replaced with the same brand/type as always.
Later in the same weekend then I was typing and began suffering from a strange random keypress problem. Q for instance, began equaling 'ew' while space started equaling '['.
Odd.
I shelved the keyboard with the intent to call Apple today.
Now I get home from work, reconnect the KB, and lo-and-behold, it works! I was thrilled. Now, after 3 hours of use, the same problems start back up. This is obviously therefore not a KB related issue but a software related issue or else it would now reliably do the same key oddities that it had been doing.
I've trashed the BT preferences and am about to restart, but I don't think it's time to buy a new keyboard just yet for those of you having similar BT keyboard problems.

The question is , the tempcombo needs double click to open dropdown. Is it possible that it appears when mouce hover over the cell or with one click ??

Hi drsantoshsinghrathore,
I made a simple with your code, and I could reproduce your issue. Based on the code, I think this behavior is expected since the tempcombo needs double click to open dropdown in your code. And if you want to achieve it with one click, I think you could remove
the "Worksheet_BeforeDoubleClick" and modify the "Worksheet_SelectionChange".
The simple code as below:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim str As String
Dim cboTemp As OLEObject
Dim ws As Worksheet
Dim wsList As Worksheet
Set ws = ActiveSheet
Set wsList = Sheets("ValidationLists")
Set cboTemp = ws.OLEObjects("TempCombo")
On Error Resume Next
With cboTemp
.ListFillRange = ""
.LinkedCell = ""
.Visible = False
End With
On Error GoTo errHandler
If Target.Validation.Type = 3 Then
Application.EnableEvents = False
str = Target.Validation.Formula1
str = Right(str, Len(str) - 1)
With cboTemp
.Visible = True
.Left = Target.Left
.Top = Target.Top
.Width = Target.Width + 15
.Height = Target.Height + 5
.ListFillRange = str
.LinkedCell = Target.Address
End With
cboTemp.Activate
Else
With cboTemp
.Top = 10
.Left = 10
.Width = 0
.ListFillRange = ""
.LinkedCell = ""

A Firmware update to address this issue didn't fix it.
Most annoying when doing searches or especially when typing passwords.

So I'm fooling myself by using this forum to attempt to get help?
There are no moderators?
No one to say...your issue is solved here...

Problems with the slight delay of keyPressed.

Hi all!
I just joined the wonderful sdn network, so HELLO EVERYONE :D
I studyed some java in unversity, but never in depth, and ive recently found myself yearning after it, so recently i decided to try and teach myself!
Unfortuantly ive hit abit of a problem, im trying to make a pacman game, hopfully develop it beyond the original and make it more innovative.
Ive come across two problems
1. My applet doesnt seem to have any focus until ive clicked onto it - i cant figure out what needs the focus and which focus method i should use or where the code should go!
2. Although ive got my pacman displayed with a nice munching motion (which im quite proud of ^_^ ) and he moves when the specific keys are pressed, theres a slight delay when i try and change direction, or when i first keyPress. Hopefully you can see what i mean when you run my code, or maybe you already know what im talking about!
I have a feeling its to do with the keyPressed code, since it only kicks in when the key is down, rather then when its keyDowning(if thats even a word!) is there a way to remove that delay so movement is seamless?
So id be very grateful if you could advise me on what my first mistake was, and what i could do with my second problem!
Thank you, my code is below, and please feel free to share some POSTIVE critisim, on my code, or advice on what steps to take next or in coding in general!
CHEERS!

Lost keypresses and mouse clicks: Hardware problem?

I recently bought an Intel MBP, and I've been noticing strange behaviors with regard to keypresses and mouse (touchpad) clicks getting lost sometimes. The problems I'm having are hard to reproduce intentionally, but I can hear the keypresses and mouse button clicks when I do them, yet nothing happens. While it's possible, that I sometimes am hitting the wrong key, I have been paying closer attention lately to this problem, and of course, the mouse button kinda hard to hit incorrectly. Here are some examples of weird things I encounter:
If I click in a text field in Safari, sometimes the first keypress (and only the first) will get lost.
Sometimes, the first keypress I type right after clicking gets lost. For instance, just now, I noticed a typo in the above sentence, so I clicked on the character and hit the Delete key. The cursor was in the right place, but the delete didn't happen. I had to press the key again.
Sometimes, even when the window for sure has focus and the pointer is squarely pointing to a link, the first click on the link won't take. I have to click it again. Since Safari doesn't have adequate feedback for when you click something, that can get particularly frustrating. Similar things happen with buttons in applications or on the title bar.
If I'm using an X11 app, and I copy/paste with the clipboard, the touchpad won't respond to movement for 2 or 3 seconds afterward. This is particularly visible with "nedit". I don't think this is an "ignore accidental touchpad input" issue, because this only happens with clipboard actions; other keys don't have this effect. I haven't noticed this with native apps.
However, I have noticed in X11 and native apps, sometimes, Ctrl/Cmd-C and Ctrl/Cmd-V will be ignored. They're never ignored if I selected the text using the keyboard (shift+arrows), but if I select the text with the mouse and then use the shortcut to copy, the copy/paste sometimes doesn't happen.
I have noticed that if I am more deliberate about clicks (make sure to hold the button down longer), the probability of losing the event SEEMS to be reduced, but not eliminated. Is there a debounce circuit involved that's causing me trouble?
This kind of loss of input is unusual to me. I have a number of Windows and Linux PCs, and I've never experienced this sort of thing. I've also used a few Macs at school before I got this one and didn't notice anything weird.
Can anyone shed some light on this for me? It would seem odd that I should have to modify my keyboard/mouse using behavior when switching to the Mac. If the problem is hardware, how can I prove it? (Perhaps I could boot Knoppix from a CD and mess around a bit.) If the problem is software, is this a case of MacOS trying to second-guess user input?
Thanks!

Theosib,
Apple regularly monitors these boards, but you may never see a response from Apple directly. Assume this is a user to user forum. If you are having a problem with the computer and need a response from Apple call 1-800-APLCARE and speak to customer relations at that office if the technician is not able to satisfy your needs.
Your problem while not unheard of, is more uncommon than the boards may make you believe.
Remember, Spotlight is constantly indexing. If your hard drive is overfull, it may take longer for Spotlight to index, thus cause a multitasking delay. If you have many Dashboard widgets, they may all be trying to access the net for updates at once, and again, a delay might happen. I've written a FAQ* about several other factors which may affect Mac OS X speed, which could in theory also affect keyboard input:
http://www.macmaps.com/Macosxspeed.html
And of course, you should always check Apple menu -> System Preferences -> Keyboard and Mouse to make sure your input settings are the ones most comfortable for you when using the keyboard. It is possible a repeat rate could cause a delay.
Edit: I attempted to answer another of your questions here recently with an update:

Please take a look and see if it answers your question.

Event problem - slow/delayed reaction to keypresses!

Hi all!
Im trying to implement a first person free mouse view with strafe in the game im working on. I use KeyListener interface and my problem is that when I hold down a key it fires a KeyEvent to begin with! Then after a delay of aproximately half a second to a second more event are being fired. It gives really slow reaction - something that I can not use in my game. What to do? If someone has a good fix to this issue please post a little code snippet I can check out.
I wish you all a good day.

It just seems easier to set a bool. true when keyPressed - false when released. And then just run while trueOf course this creates an infinite loop which uses up the CPU resources. Not a very good idea.
Yup, my thoughts exactly (see reply #4).Using a Thread or a Timer is a similiar in concept (much better then the above suggestion), but there are differences.
For example when using a Thread your code will execute then you will sleep for a period of time. So if your code takes 100 milliseconds to execute and you sleep for 1000, then every cycle will take 1100 ms. The total length of time between events will vary between CPU's since the 100ms execution time will vary depending on the speed of your CPU. However, when using a Timer an event will fire every 1000ms whether your processing takes 100ms or 500ms. Which means your cycle time is exactly 1000ms.
Using a Thread you must use the SwingUtilities.invokeLater to update the GUI since the code executes in a non Event Thread. However when using a Timer all the code executes in the Event Thread so you don't need to worry about SwingUtilities.invokeLater. Of course if your code is heavily CPU bound you may need to create a separate Thread anyway so you don't block the Event Thread from responding to events.
But the main point is using a Timer will give you a cycle time of a fixed duration, whereas using a Thread will give you a variable cycle time depending on CPU and duration of executable code.
The choice of implementation is up to the OP.

Problems with event KeyPressed?

Hi,
I want to know when a user is typing, some text, but the keyPressed event is only used, in canvas, and i m not using, canvas, i m only using simple GUI controls... is there any way to know when a user is typing text, or to know when there is nothing written, in a textbox, dinamically?
Cheers,
HELP MEEEEEE!!!!!

hi,
that u have to implement through coding there is no such method like that.
I have implemeted the text box concept in the Canvas clas previously like that

Ibook G3 keyboard problem: one keypress causes many characters to appear...

I have seen a iBook G3 (dual USB) for sale that I might purchase, the only problem is that the seller says that when he presses any of the F2, 2, w, s and x keys, it displays the results as if all the keys were pressed simultaneously. All these keys are aligned diagonally if you look at the keyboard. My question really is is this possibly a software issue or is it hardware?
Thanks in advance!

Hi, and welcome to Apple Discussions.
This is most likely a hardware issue which will require replacing the keyboard.
If the iBook still has its OS 9 installation, you can check to be sure by restarting into OS 9. (System Preferences > Startup Disk)
If it happens in OS 9, too, you can be certain that the keyboard needs to be replaced.
