registerSuper(program,handle)

Use this function to register a new super program in QAD ICT. The developer can register that

program as a super program (all internal procedures or triggers defined in the program will be

available during the session). Parameters that should be passed in the function are program (a

string that specifies the name of the program) and handle (handle to the program that should be set

as persistent). The difference between registerPersistent and registerSuper is that when using

registerPersistent the developer who wants to run an internal procedure from a persistent one must

specify the handler to the procedure where the internal one is located. Using a registerSuper, the

system will execute the one that was loaded last.

Example

{mfdeclre.i}

{icdef.i}

…

if not (qad_key5 = "" or qad_key5 = gsvICTTaskID) then next.

if session:add-super-procedure(getProcHandle(qad_key2, false)) then do:

if existsInSuper("HandleEvent") then

registerSuper(qad_key2, getProcHandle(qad_key2, false)).

end.

registerWidget(program,widget,handle)

Use this function to register a widget in QAD ICT. When a new widget is created or retrieved

during processing, the developer can register that widget. Parameters that should be passed in the

function are program (a string that specifies the name of the program), widget (the name of the

widget), and handle (handle to the widget that should be registered).

Example

{mfdeclre.i}

{icdef.i}

create fill-in lvwWdg

assign

name = entry(3,ttic_key2)

frame = lvhFrameHdl

data-type = ttic_charfld[2]

format = ttic_charfld[4]

col = FCOL(ttic_charfld[5],ttic_charfld[6])

row = FROW(lvhFrameHdl,ttic_charfld[5],ttic_charfld[6])

sensitive = no

registerWidget (entry(1,ttic_key2),

lvwWdg:name,

lvwWdg:handle).

registerShadow(identifier,rowid)

Use this function to register a shadow table in QAD ICT. When the record of a shadow table is

found (for example, using a find statement) and registered using the registerShadow function, the

developer can retrieve that record in any other program using the getShadow function (see

page 10). Parameters that should be passed in the function are identifier (a string that specifies the

name of the table) and rowid (rowid to the record that should be registered).

define variable lvc_variable as character no-undo.

registerValue(“my_value”, “test”).

…

lvc_variable = getValue(“my_value”).

getBufferValue(buffer,field,index)

Use this function to retrieve a particular value from the buffer. One output parameter is passed

back by the function: a character value (value of the variable). The input parameters for the

function should be buffer, field (a string that determines the field name from which the value

should be retrieved), and index (expression representing a subscript, for fields that have extents).

For a field that has no extents, the index should equal 0 (zero).

Example

{mfdeclre.i}

{icdef.i}

find first pt_mstr no-lock no-error.

registerBuffer("pt_mstr", buffer pt_mstr:handle).

display getBufferValue("pt_mstr", "pt_um", 0).

getShadow(identifier)

Use this function to retrieve the record of a shadow table that was previously registered using the

registerShadow function. One output parameter is passed back by the function: a rowid to the

record. The input parameter for the function should be the identifier (a string that determines

which record should be retrieved).

Example

{mfdeclre.i}

{icdef.i}

define variable i_rowid as rowid.

assign i_rowid = getRecord(“xxpt_mstr”).

for first xxpt_mstr where rowid(xxpt_mstr) = i_rowid exclusive-lock:

end.

Screen (Widget Walker) Manipulation Functions and

Procedures

The developer can use one function and one procedure to manipulate the screen.

getFieldValue(variable,frame,property)

Use this function to retrieve information from the screen. One output parameter is passed back by

the function: a character value. In that value, the function can pass back the value, label, or a

handle to the field or frame, depending on the input parameters.

The input parameters for the function can be:

• Variable. String that determines the name of the field that is displayed on the screen.

• Frame. Name of the frame in which the field is displayed.

• Property. The string that determines what kind of information should be retrieved. The

property can be SCREEN-VALUE, LABEL, or HANDLE. (Using a handle, you can retrieve

all information for the field; it is very flexible.)

Example

{mfdeclre.i}

{icdef.i}

define variable i_handle as widget-handle no-undo.

define variable lvc_value as character no-undo.

assign i_handle = widget-handle(getFieldValue(“pt_part”,”a”,”handle”)).

assign lvc_value – i_handle:format.

setFieldValue(variable,frame,screen-value)

Use this procedure to set the value in a field that is currently displayed on the screen. The value is

only set on the screen—not in the database.

The input parameters for the procedure should be:

• Variable. String that determines the name of the field that is displayed on the screen.

• Frame. Name of the frame in which the field is displayed.

• Screen-value. The string that determines the value that should be specified in the field.

Example

{mfdeclre.i}

{icdef.i}

run setFieldValue(“pt_um”, “a”, “kg”).

Note When the field that is displayed on the screen was previously added using Frame & Field

Properties Maintenance, the developer must define the first parameter as table_name.field_name

to set the value in it. In the example shown above, if pt_um is added using Frame & Field

Properties Maintenance, the execution of the function should contain the first parameter as:

run setFieldValue(“pt_mstr.pt_um”, “a”, “kg”).

Additional Functions and Procedures

firstTime(identifier)

This function allows you to execute the block of custom code only once for each record. The input

parameter for the function/procedure should be the identifier (string value) for the currently

processed record. The output parameter is a logical value (true or false) that indicates if the

saveFirstTime procedure was executed for the current record.

Note When using firstTime for custom pop-up frames, developers should be aware that if there is

a validation error somewhere in standard code, the pop-up frame will not appear again and

previously filled-in values will not be stored.
