AfterValueChange event

Hi everybody,
I tried removing the requestfocus() call and did
not see any change. I have found that if you set the widget to a new
value, the problem goes away.
for eg, whenever the validation fails, after the call to purgeEvents()
iam doing this
Amount_dedC.value = 0.0;
Is this the right behaviour?
Thanks and regards,
Shailendra

Thanks for the replies so far, but this is not the problem. I know about
the "Validate on keystroke" option and it is definitely swithed off.
I was rather thinking along the lines of this being be a 'funny' in
Forte. Has anyone seen this before? Here is more information:
1) The windows that it is happening on all have parent windows.
2) The fields with this problem are all part of a mapped gridfield, ie.
it has a type.
However, I have constructed a test class with these characteristics, but
it is no good. There must be something else that could cause this. Any
ideas?

Hi Jaco,
Check if the option "Validate on keystroke" is set
to true on the widget that posts the AfterValueChange.
If so, than that's the reason. Turn it off and your
problem will go away.

Hi there,
I'm hoping that someone out there has experienced the following (and
knows why it is happening. ) :-)
I have a couple of windows on which the AfterValueChange event is
triggered on a field upon hitting the delete key.
We all know that this should only happen upon leaving the field, ie.
the
field loosing focus. The problem is that I'm trying to recreate this
in
a simple test class, but now it won't happen. I still have the
original
windows on which it is happening, but I would like to construct
something small and simple to send to Forte.
Any ideas as to why this could be happening?
Many thanks in advance.

JacoIs the "Validate on KeyStroke" property turned on for the widget in the
original window? I believe the AfterValueChange gets triggered every
time you hit a key if it is.
I can't think of anything else, off the top of my head. I haven't had my 1st
pot of coffee yet....

Hello Jaco,
i could not reproduce the problem you have. The best way for a help in your
case is a little sample which may be modified by others (forte-users).
Please attach your PEX-Code in your next reply and describe it.
I'am absolutly sure that we are able to give an helpfull answer.
One question forward: 'Do you use the FunktionKey-Event in your Window(s)?'
Sorry, but no other way exists to resolve your problem (We/I'am too far,
for making a visit :-) ).

Radio List events

I've noticed a quirk (imagine that) with Forte radio lists and am
wondering if there is a known work around. Here is the problem:
We are trying to catch the value of a radio list. We want the value
that the user inteded by his/her click, so we register for the
AfterValueChange event. Ordinarily this work fine, but an error ensues
when the user clicks for a second time the calue that they just clicked.
Error:
DEVELOPER ERROR: Attempt to invoke method which is invalid for
DataValue object with Null Value
A double-click will do this as well when registered for the
AfterValueChange event. Registering for the Click event is no good
because the value has not yet changed to what the user intended. The
value is still at the same place prior to the user click.
Does anybody have any light that they'd like to shed on this one? Much
thanks in advance. :)
Sincerely,
Gregory J. Dalbey,
May&Speh

It works fine for me - I can email a simple example if you need it.
I've noticed a quirk (imagine that) with Forte radio lists and am
wondering if there is a known work around. Here is the problem:The quirk is Developer Error.
We are trying to catch the value of a radio list. We want the value
DEVELOPER ERROR: Attempt to invoke method which is invalid for
DataValue object with Null Value
Based on the error message you described, I predict that your radio list
widget has a mapped type of integerdata, and it doesn't have any memory.
There are at least 2 solns:
A. If you change the mapped type to integer you wont need to '=new;'
memory for the widget, but you loose the power of the integerdata class.
B. If you keep the mapped type to integerdata, then you need to edit the
'Init()' method by adding a line which says radiolistAttrib = new;
and your problems will be corrected.

RE: Legacy Integration with PI/Open

Greg -
We are currently working on wrappering the APIs for UniVerse (aka Pick on
UNIX).
We received some help from the guys at RTD in Denver.
We tested out a C program that uses the Universe APIs and it works fine.
We will be building the Forte piece and compiling it this week.
Our first application is to inquire the UniVerse data, after that is
successful, we will move to inserting & updating.
Let us know how we can help.

Subject: RE: Forms That Will Not Close
Exiting the event loop will not close the window! Invoking
'Close' method on the window will. Check if this method
is executed. It appears, the AfterFinalize event exits the
event loop and nothing more. Then, your applications

Enter', before invoking Window.Close().
Pascal
Hi,
We seem to be having some type of deadlock problem when trying to
close
forms and am wondering if anyone else has experienced this problem.
The
phenomenon does not always occur and is not specific to any one client
machine.
I will explain the phenomenon:
1. We have an object that contains our main application startup
method.
This method then instantiates our main application window (Control)
and
invokes the Display() method using start task.
2. All other forms created by the application are created using a form
manager service object which exists on the client partition. The form
manager has a CreateForm() method which instantiates a form class of
the
specified type and invoked the form's Display() method using start
task.
3. Each form has a Close push button which when clicked invokes
Window.RequestFinalize().
Now, the problem we have is this:
The user starts the application and the main application window is
displayed. The user then selects an option from the main window and a
child form is created using the form manager service object and is
displayed. The user can continue to create more child forms by
selecting
options from the main window and all child forms are instantiated and
displayed correctly.
However, when the user attempts to close one of the forms the form
does
not close. The finalize event is triggered and the event loop is
exited,
but the form continues to be displayed and does not close. If the user
then moves the mouse pointer over the main application window, the
child
form immediately closes. Moving the mouse cursor over other child
windows (or even the desktop) does NOT do this - only when the mouse
cursor is moved over the main window does the child form close.
Does anyone have any ideas on this?

Jace.

Subject: RE: Forms That Will Not Close
Jason,
No, self.Close() should close the window. This is the
method I referred to. You could place a traceline
behind self.Close() to see if it is executed. It is not
inconcievable some exception may exit the Display()
method before self.Close() is executed.
After that, maybe, some events from your main
window trigger something that causes a call like 'My-
Window.Close()', where 'MyWindow' is a subclass of
'UserWindow', so 'MyWindow' gets closed after all.
Maybe you've overridden 'Close()', so now it doesn't
work properly anymore.
Are you sure you exit the event loop after you press
the close button?? The display method is not regis-
terred for any <PushButton>.Click event, though maybe
you just didn't include the full Display method in your
mail.
Remember that an event loop will only respond to an
event if it is not currently handling an event. So, the
method behind <PushButton>.Click may call a self.
Window.RequestFinalize(), which will cause an After-
Finalize event to be posted, which will be placed in
the event queue. If this method however keeps waiting
for something, the event loop will not respond to the
AfterFinalize event, until this method is done waiting.
Pascal.
Hi Pascal,
The Display() method is as follows:
self.Open();
event loop
when Window.AfterFinalize do
exit;
when task.Shutdown do
exit;
end event;
self.Close();
<end>

"C". We could wrapper these from within Forte, however the issue is that
the APIs provided are non-shared, and Forte requires shared libraries.Would be interersting, which operating system you're using.
You could write a dll (on windows) or shared library (on unix) wrappering the
original,statically linked "C"-Libs. This lib could be used by Forte.

RE: RE: Function keys and droplists

I had to implement the same problem in a window. I wanted Ctrl-F to be the
same as the "Fetch" button. I forgot the SetAsFunctionKey existed, so I
created a Menu choice with a shortcut of "Find." I have had no problems,
when
Ctrl-F is pressed the "menuWidget.activate" event is posted and no keystroke
events are sent at all.

It is a general problem with the SetAsFunctionKey method that the
default behaviour of the key - which is present if you do not call
SetAsFunctionKey - is not disabled after the key is used as function
key. We have this problem under Windows: the F10 key has a default
behaviour of activating the window's menu. Now if you set F10 as
function key, the corresponding Forte event is posted to the window
but
the menu is still activated. Forte refuses to acknowledge this as a
bug,

Custom Scroll Bar (value before mouse buttonrelease)

Hi Forte Users,
Has anyone been able to modify the scroll bar so that the value was
continually updated?
Basically I want to be able to change a value in a DataField while the
scroll is moved, not after the mouse button is released.
The AfterValueChanged event will only be posted once the mouse button is
released therefore I used a Timer.Tick event to continually poll the scroll
bar for its value but found that this value also only changed when the
mouse button was released.
Any help would be appreciated,

RE: (forte-users) Is there a later version than Forte v30L2?What 's th

Hi,
We have recently upgraded to 30L4, and Forte say that this fixes a
corruption problem with the repository to do with large projects.
This patch also fixes the problem with AfterValueChange event on
FillInFields.
Upgrading was simple for us as we don't use Express.
R4 is still next year some time as far as I know.

I know system management for SynerJ is more complicated. I just got the
1.4.1 version of SynerJ and it has completely changed on how partitioning
work regarding the EJBs. Just more to learn to do the same thing we did in
Forte.

Hi,
I guess many people is interested in finding out how different it is
between SynerJ and TOOL.
Here is something to share.
1. Forte is posting all manuels ( SynerJ, Fusion, Conductor ) on the Web.
You just need a customer login in. Here is a good start.
2. java.sun.com now has a beta document J2EE APM which explain the
architectual of J2EE. The document how and when you will use JSP,
Servlet, EJB & Java Bean etc. You will find it along with the J2EE beta
free download.
My feeling is: on system management level, SynerJ is more or less similiar
with what we have now ( maybe they jus rewriting everything in Java ).
However, on development and design level, there is quite a large
difference. Nevertheless, it's exciting.
Regards,
Peter Sham.

Hi Dave,
You have no chance to catch this exception in aftervaluechange block.
This event is triggered if the value in DataField is OK.
You get only Arithmetic exception without the aftervaluechange event if the
length of the decimal is greater as 28.

SetAsFuncitonKey() and shortcut keys

SetAsFuncitonKey() seemigly provides shortcut key functionality -- but this
proves not to be the case as once you register a key as a funciton key,
anytime you press that key, whichever widget has focus will post an
AfterValueChange event. This creates a lot of conflicts once you register
a bunch of function keys and do some validations on AfterValueChange.
Workarounds might include the ability to register key+modifier with
SetAsFunctionKey() or to have a reason attribute on the AfterValueChange
event -- but neither currently exist in Forte.
Does anybody have any workarounds so that using SeyAsFuncitonKey() does not
result in the extraneous AfterValueChange events?
If not, does anybody have any good workarounds for creating shortcut keys
-- without having to use the menu bar.
Thanks.

Hi:
If you didn't install the chipset and graphics drivers for your model you won't be able to change the screen brightness or adjust the screen resolution.
First, install the amd chipset drivers and reboot.

Then install the graphics driver and reboot.

Then install this software to get all of the special Fn keys to work.

Re: (forte-users) Formatting DecimaNullable withTemplate

Hello Fabrizio,
i don't look at your window, but we has the problem to check the input of a
DecimalData
with a specific mask. If the user type in wrong data (prescale/sucscale)
then we have
to inform the user and discard the changes.
E.g. template='##,##'
User types 5,123 Exception (Too many sucscale)
User types -5,12 Exception (no Minus allowed)
User types 123, Exception (Too many prescale)
User types 12,12 No Exception (Value is accepted)
User types 12,12+ No Exception (Value is accepted)
The template check is implemented in the FillString/SetValue method of an
inherited DecimalNullable-Class. I am wondering, if it is not possible to
find a way
reacting on your behaviour. You use a Domain.
1. You have to implement the SetValue/Fillstring method for this domain.
2. You must turn on KeyStroke reacting.
3. You have to implement an EventHandler for reacting on the input which must
be registered on your Display-based Event-Loop.
4. MayBe som Code must be called from your Domain-Class on AfterValueChange
Event
at your Domain.
A lot of work, i know. Maybe a lot of code for every Domain-Use in your
Event-Loop. We
made an Enhancement-Request for our problem, but there ar no solution now
(2 years).
The next problem you may have, if you use many attributes in your Domain.
Because
the transport (Serialize/Deserialize/Allocation) eats a lot of Performance.
Direct filling from Database maybe a risk (SetValue-method with Parameter
string).
You have to check if you fill your class from implizit methods
(GetValue-Method from
DBDataSet) and so on that no code will running (Performance).
Good Luck
Joseph Mirwald
PS: Use Decode-Method if possible instead of own implementation of
string-manipulation
because Framework-Lib-Calls ar much mor performant.

Hallo there,
I wonder if there is someone who ever tried to obtain the following

Using a user-defined domain based on a DecimalNullable, we would like to
set the input mask (and/or its template) in order to have the widget
behaving like a normal desk or pocket calculator. That is when start
typing, you enter the integer part of the number (with thousand
separator), and only when the dot is entered, you can type in the
decimal part.
We tried different templates but we never got what we want. Moreover,
using 3.0.N.0 we also discovered a bug while using as first character
in the template.
Enclosed there is a little test window.
Is there anybody who could help?
Thank you in advance for your attention

Thank you Joseph and thank you Zenon, for your answers.
Yes, we tried with domain, implementing the FillString/Setvalue methods,
and using the Decode method. And indeed is the decode method that always
(no matter which regional settings you have) round the decimal part to 2
digit.
Nonetheless, I would be interested to receive if possible the domain you
implemented, Joseph. We may still discover something... ;-)

Overflow Exception that I can't catch...

The problem is:
I have a DataField, mapped type :DecimalNullable
the input mask is set to Template ( #,##0;;;;)
Because it is Template I can't validate on keystroke and
I can't set the max characters in the properties sheet.
This works great until, Someone enters over 28 characters into the field.
It then displays the errors:
USER ERROR: Operation caused arithmetic overflow
Class: qqsp_ArithmeticException
Error #: [301, 7]

Hi Dave,
did you try this:
event loop
Begin
when ..... do
when <est_daily_rev_amt>.aftervaluechange do
when ..... do
exception
when ex:ArithmeticException Do
End;
end loop;
As far as I remember it matters where you put Begin
inside an event loop. This way you will catch the
exception without dropping off the loop. If the value
is O.K. the aftervaluechanged event will be executed.
Hope that helps!
Rumen
Thanks Zenon,
You mean... that without the aftervaluechange event,
I could catch
this?
Because by no means is my exception block anchored to
that event.
I am looking for advice of where I could put this
exception block...if
there
is another possible place at all.
Thanks.
Dave-----Original Message-----
Hi Dave,
You have no chance to catch this exception in
aftervaluechange block.
This event is triggered if the value in DataField is
OK.
You get only Arithmetic exception without the
aftervaluechange event if
the
length of the decimal is greater as 28.
