Link Module Attribute with Dialog Box Element

Dear Sirs,

every time that I have to create a custom GUI (by means of DXL) to update attributes it is quite painful.

Below is report a classical example how I handle the synch between the attribute and the dialog box element:

Module mod = current
string modName = name mod

DB win = create(mod, "Link Module Attribute with Dialog Box Element")
DBE fld = field(win, "Prefix: ", mod."Prefix" "", 50)

/* callback function to update the module attribute using the value of the dialog box element */
void UpdateModAttr(DBE dbe)
{
mod."Prefix" = getBuffer dbe
return
}

/* callback function to update the dialog box element using the value of the module attribute */
void UpdateDBE(Trigger attrEvent)
{
set(fld, mod."Prefix" "")
return
}

/* set the callback function of each dialog box element of the collection */
setTextChangeCB(fld, UpdateModAttr)
trigger(module->modName->attribute->"Prefix", modify, 20, UpdateDBE)

realize win
show win

It would be nice to have this handing directly in the definition of the DBE.

In other worlds, instead to have:

DBE field(DB box, string label, string initial_value, int width[, bool read_only])

to have:

DBE field(DB box, string label, Attr__ synch_attribute, int width[, bool read_only])

or also to have the possibility to set it after the definition of the dialog box element:

set(DBE dbe, Attr__ synch_attribute)

Of course, not just for field dialog box element but for all other elements.
