[jawsscripts] Re: Skipping screen

thanks for your reply. Hitting the spacebar moves to the next screen.

This Bible software does not use the PC cursor in the text area but it must 
be there for the built in keystrokes to work. so PCToText is a script I 
wrote to make sure the PC cursor and JAWS cursor were in the text area.

I didn't catch the refresh after each line in the while loop. that may be 
doing something. I only need this once per screen. some books use some 
characters which cause JAWS to repeat lines unless refreshed.

Thanks for pointing out about the two JAWSCursor calls. Idon't think they 
are bringing up the invisible cursor but will checxk it out.

| Hi Dean:
|
| first a few questions.
| What does pressing the spacebar do?  does it move to the next page?
|
| What does PCToText () do?
|
| Also,  Is it really necessary to refresh the window for each line
| within the while loop?
| Doing this so often will cause a sort of flashing effect and may also
| trigger other events. minimizing this would be helpful.
|
| I also noticed within the TopOfText function that you activated the
| Jaws cursor at one point, and then activated the jaws cursor again
| within an if condition.  this could cause the invisible cursor to be
| activated,  since performing two Jaws cursors within a short period of
| time will activate the Invisible cursor instead.   I will copy the lines
| I am referring to below.
|
| PCCursor ()
|
| TypeKey ("spacebar");new keystroke in Libronix 3c
|
| Pause ()
|
| JAWSCursor ()
|
| If FindString (GetFocus (), CurrentLine, s_bottom, s_restricted) then
|
| JAWSCursor ()
|
|
| 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.
|
| I will copy the ScheduleFunction entry from the fsdn below.
|
| HTH
|
| Function: ScheduleFunction
| Description
| Runs a user defined function in a set period of time. Useful when you
| want to perform a task and then check on the results at a later time.
| Once this function is used, you can call UnScheduleFunction to cause the
| user-defined event not to run.
|
| Returns
| Type: Int
| Description: An ID that can be used to call UnScheduleFunction. If 0 is
| returned, then the timer was not successfully set.
|
|
| Parameters
| Param 1:
| Type: String
| Description: Name of function to be executed.
| Include: Required
|
|
| Param 2:
| Type: Int
| Description: Amount of time to elapse before the function is executed.
| Time is measured in tenths of a second. A value of 10 is one second.
| Include: Required
|
|
| Version
| This function is available in the following releases:
|
| PAC Mate 1.10 and later
| JAWS 4.51 and later
| Magic 10.5 and later

| I am trying to get the combination of the two following to read a
| screen of
| text then move to the next screen and red it, etc. It wil read the
| first
| page then repeat the last line which may be the first line of the next
| page.
| It might read another line or two then skip to the next screen. Does
| anyone
| know why it might be skipping? It seems like the movement between
| screens is
| faster than JAWS can read the screens. Is there any way to slow this
| down
| without using the delay function:
