Working
|I initially responded to Dean's post and suggested that he use the
| ScheduleFunction in his TopOfText function.
|
| From my original message:
| The timing issue you mention could be rectified if you used the
| ScheduleFunction to run a function that contained the code from your
| function which came after the press of the space bar. This of course
| will have the effect of breaking your TopOfText function in to two
| functions. You will need to make any variable that was defined in the
| TopOfText function that is used in the new function a global variable
| so that it's value can be read in the new function. This will allow you
| to increase the time before this function is called to an appropriate
| amount.
|
| His problem is not really the ScheduleFunction so much as it is a
| problem of having two while loops running simultaneously.
|
| In his ReadContinuously script he sets up some variables for schemes
| and other things, then he runs his TopOfText function. So far so good.
|
| In his TopOfText function he activates the Jaws cursor, loads a couple
| of string variables to hold the current line and last line. and sets up
| a variable which will become true if a key is pressed during the while
| loop in this function.
|
| Now while loop runs until key is pressed or until last line and current
| line are equal.
| He needs to remove the following lines from his TopOfText function in
| the while loop:
| If iKeyWasPressed then
| Return
|
| This causes control to go back to the script that called TopOfText
| Immediately. His loop will not be entered again after the key was
| pressed so the return is not necessary here.
| He checks for this condition immediately after the EndWhile for his
| loop.
| He could use the following if in his while loop.
| If iKeyWasPressed ==0 then
|
| SayLine ()
|
| Let LastLine = CurrentLine; sets up for new comparison
|
| NextLine ();scrolls down one line
|
| Let CurrentLine = GetLine (); saves the new line
|
| EndIf
|
| After the while loop ends he checks the value of the iKeyWasPressed and
| returns if this is true.
|
| I suggest that he changes the schemes as appropriate in this if and set
| up the Reading of verses as appropriate here before returning. much of
| this code already exists in his ReadContinuously script.
| So the rest of his TopOfText function could look something like this:
|
| If iKeyWasPressed then
| set up schemes and verse reading etc.
|
| Return
|
| Else
|
| PCCursor ()
|
| TypeKey ("spacebar");new keystroke in Libronix 3c to go to next screen
|
| scheduleFunction ("PositionForNextRead", 2)
|
| EndIf
|
| EndFunction
| His new PositionForNextRead function would contain the rest of the
| Lines taken from the TopOfText function:
| Void function PositionForNextRead ()
|
| Say ("next page", ot_status, false); for testing purposes
|
| JAWSCursor ()
|
| If FindString (GetFocus (), CurrentLine, s_bottom, s_restricted) then
|
| NextLine ()
|
| Else
|
| JAWSPageUp ()
|
| JAWSHome ()
|
| EndIf
|
| RefreshWindow (GetCurrentWindow ())
|
| TopOfText()
|
| EndFunction
|
| Doing things this way means that you no longer need to use another
| while loop in the ReadContinuously function because the topOfText
| function is called again in the PositionForNextRead function.
|
| As I mentioned previously, this approach will require a few new global
| variables. The while loop in the ReadContinuously function should be
| removed and the schemes etc. can be set up again in the TopOfText
| function.
|
| That's my take on it for what it's worth.

| Hi list, I thought I'd just rePost Dean's issue since I hadn't seen
| any
| responses to it yet, and hoped that a reminder might help if anyone has
| time
| to take a look?
