[Pscan-dev] Custom Events

Here's the link at google (with previous/prior posts).

[Curtis W. <dy...@an...>]

>1. I'm pretty sure more needs to be added to the loop to handle all necessary events.

Yes.  The events we need to handle are button presses on the ResultsForm.  We will have to do this manually.  Fortunately, with the buttons, we will only need to do like one or two function calls (like, FormGotoForm() if the "New Scan" button is pressed, ScanClose() if the "Stop Scan" button is pressed, etc.)

I've moved the loop to the top of ResultsFormHandleEvent().  Also, I've moved the button handling to a new function:  ResultsFormHandleButtonEvent().  The new function is called from two places within ResultsFormHandleEvent: in the scan loop, and in the switch statement.

a. In the scan loop, the return from ResultsFormHandleButtonEvent() is checked.  If true, the event loop portion is stopped and the scanstop var is set.  If not, the event loop continues.  Then, the scanstop variable is checked (at the very end of the scan loop).  If true, break, else continue.

b. In the switch statement, I don't do any checking for the result--I just set handled equal to the ResultsFormHandleButtonEvent() return value.

>2. binary craps out when you click the scan button.  Says something about calling a shared library that doesn't exist or something.

I'm having trouble with POSE.  For some reason I can't transfer my ROM.  Anyway, I'll work later when I get a chance on getting a ROM and checking it out.

I can't compile this because of my recent upgrade, so I'll let you do it if you can.  If you have any questions, you know where to find me.

Curtis.

[Pscan-dev] Re: To ponder

[Dave <d.m...@ho...>]

Cool.  I'll take a look and see what I can find.  I haven't had a chance to
do anything today because I was at camp all day.  Hopefully tonight I'll
bust out.

I recall someone mentioning something about events on the plucker dev list.
Maybe a look through that code will help out.

However, I can't figure out how to read the id of the posted event (i.e., I
can set it id, but not check it).  This is not very useful.  Let me know if
you come up with anything.

[Pscan-dev] Custom Event

[Curtis W. <dy...@an...>]

I'm trying to figure out the best way to implement the scan through 
the event manager.  Basically, we don't want to do our own loop 
because then you would have to go through the entire scan before 
it goes back to the event handler.  If we're going to be creating 
a results field, this could potentially overflow the event queue.

I think the best thing to do is simply create a custom event (pscanScanEvent?), 
but documentation on such a thing is sparse.  All I've found so 
far is one mailgroup post that says a guy was thinking of creating 
a custom event.  Of course, he didn't mention how he was going to go about doing that.

Any ideas or any references would be helful.

Curtis.

[Pscan-dev] PScan

[Curtis W. <dy...@an...>]

Yo,

I've been busting out.

1. Created ResultsForm.
 a. Results field
 b. Save as: Memo/Doc (just the list, doesn't actually save)
 c. Stop Scan button
 d. New scan button (takes you back to main form)

2. Added "Edit" menu.

Doesn't sound like much, but it took me a little while because Pilrc doesn't have a GUI preview like it used too!  Also, I was messing around with the popup list control, but couldn't get it to work right, so I said screw it and went to a regular list instead.  Doesn't look bad.

Also, I added a scrollbar resource, but I can't get it to show up.  Any ideas?  The pilrc manual is at http://www.ardiri.com/index.cfm?redir=palm&cat=pilrc&subcat=manual

Right now, Scan() is called before going to ResultsForm, which means the scan is completed before going there.  I'd like to change this, but as we discussed last night, not sure how exactly to do it.

Anyway, here's the zipped code.

Curtis.
