Hi Steve, hi Bob,
to check if a key is assigned to a script one can also use the function
IsScriptKey(). But I don't know how to stop it if TrapKeys and the hook
not working.
Reading for keys in the ini file is sensitive to errors because you
don't know if to search for "Control+Alt" or for "Alt+Control".

Thanks Bob, that's an option. I suppose I'm just trying to be lazy, as this
app has a few hundred scripted keys. Either way I'm going to have to
specify the keys or specify what to look for. Good news at the moment, I
have it all working as I want it to, just need to add the actual keys I want
the help to recognize. THX Steve.

You could use inireadstring on the jkm file to test if the keystroke is in
use for this app.

Hi Udo. I've tried the trap keys method and I'm still having unscripted
keys (application default/unscripted keys) executed. Apart from that it
works great.
I'll try the hook method and see if this makes any difference, as I
basically want it to work the same way the default keyboard help works.
This doesn't allow any unscripted key to be exacuted The trap keys method
seems to me as if all possible combinations have to be specified, rather
than just saying something like:
; if a script is associated with a keystroke
If IsScriptedKey() Then
; run the script, as the script is only speaking a message
Else
; if it's not a script, it's a native app key
Do nothing and just announce the key
EndIf
That seems to simplistic I know lol, but I would have thought this was
possible. Specifying all script keys seems pretty overkill....but I know
things are never that straight forward <grin. THX Steve.

Hi Steve,
you don't need a hook necessarily. You can use TrapKey only for getting
control of the keys. For example:
<begin code>
; assign a shortcut to StartTrap to begin the trapping
Script StartTrap ()
TrapKeys (True, False)
EndScript
; end the trapping either by assigning a shortcut or by pressing ESC
(see ProcesskeyPressed)
Script EndTrap ()
TrapKeys (False)
EndScript
; here is the checking of the keys
Void Function ProcessKeyPressed (int iKeyCode, string sKeyName, int
IsBraille, int IsScriptKey)
; react on pressing F1
If sKeyName == "F1" then
SayString ("You pressed F1")
EndIf
; other keys ...
; End the trapping
If sKeyName == "ESCAPE" Then
PerformScript EndTrap ()
EndIf
; pass the function to other scripts
ProcessKeyPressed (iKeyCode, sKeyName, IsBraille, IsScriptKey)
EndFunction
<end code>
By the way if you need to process you own scripts, you can use the hook
too. For example:
<begin code>
; assign a shortcut to start trapping and the hook
Script StartHook ()
; Start hook function "MyHook"
AddHook (HK_SCRIPT, "MyHook")
; trap the keys
TrapKeys (True, False)
EndScript
; end the hook either by assigning a shortcut or by pressing ESC (see
ProcessKeyPressed)
Script EndHook ()
; no more trapping
TrapKeys (False)
; remove the hook
RemoveHook (HK_SCRIPT, "MyHook")
EndScript
; in the hook function you can decide which script to run
void Function MyHook (string sScriptname)
; if the script name is "YourScriptName" then
if sScriptName == "YourScriptName" then
; allow execution
return True
endIf
; if you want to end the hook you should allow EndHook to run
if sScriptName == "EndHook" then
; allow execution
return True
endIf
; no execution for other scripts
Return False
EndFunction
; Check for key pressing
Void Function ProcessKeyPressed (int iKeyCode, string sKeyName, int
IsBraille, int IsScriptKey)
; If F1 is pressed
If sKeyName == "F1" then
; execute your script
PerformScript YourScriptName ()
EndIf
; If ESC is pressed
If sKeyName == "ESCAPE" Then
; unhook and don't trap keys
PerformScript EndHook ()
EndIf
; pass event to other scripts
ProcessKeyPressed (iKeyCode, sKeyName, IsBraille, IsScriptKey)
EndFunction
<end code>
But be careful: the hook is still running if you switch to other
application so it's a good idea of releasing it in the AutoFinishEvent.
Hope this helps and good luck for your app

Hi, thanks so much. I'll take a fresher look at this tomorrow, as I feel
I'm
nearly there. I've currently just copied across the keyboard help,
KeyboardHelpHook and UnhookKeybaordHelp to my scripts. I can add my own
scripts to speak in the Keyboard HelpHook function, but stopping non
scripted keys are still getting through. I'm missing something, but
hopefully I'll see it with a refreshed brain :). Thanks again. Steve.

Hi Steve,
I'm not sure if I understand you.
If you install a hook in your application, for example
AddHook (HK_SCRIPT, "MyHook")
then inside the hook function "MyHook" you can allow a script to be
executed or not. All scripts had to pass the function and you alone
decide which scripts to execute.
If you further trap the keys with the TrapKeys function then the keys
were not sent to the application.
In the KeyPressedEvent of you application (or the like) the keys are
still arriving. So here you can decide what to do (for example start
your own script, end the hook and so on).
But please remember to uninstall the hook at the end. Otherwise the
default scripts are not running any more.
Hope this helps a little

Hi, a question on Jaws keyboard help.
I currently have a working solution that allows a user to turn on
keyboard
help and get descriptions of specific keys in any particular window.
All
of
this information is in a set of scripts that you switch to when pressing
jaws key plus 1. It maybe not the most elegant solution, as it still
allows
any undocumented keys to be processed by the application.
So, looking at the Jaws help, I'm wondering if anyone knows if the
default
script could be modified to access the assigned keys I have, while
ignoring
any other key, so not letting it be processed. The lines of interest in
the
default jaws cripts are I think:
AddHook (HK_SCRIPT, "KeyboardHelpHook")
; ignore any keys not attached to scripts
TrapKeys(TRUE)
CaptureAllGestures(TRUE)
The line:
AddHook (HK_SCRIPT, "KeyboardHelpHook")
looks to me as if this "KeyboardHelpHook" is where the information is
taken
from. Of course I am probably totally wrong, but if I could find this,
it
may give me clues to what to do. Otherwise, is there a way to use this
default script, but use information/keys I have in a set of scripts/ jkm
files etc.
THX Steve.
