PA_NewDialog PA_Dial4D
| Parameter | Type | Description | ||||

Description
The routine PA_NewDialog creates a new dialog context and returns a reference to that context. This context will be used in any subsequent call referring to this dialog.
A dialog context handles the dialog variables so that the dialog can be used in compiled mode.
Calling this routine should be the first thing done when using a 4th Dimension Dialog.
In the improbable case where it could not allocate the context, PA_NewDialog returns 0L.
Example
Display a dialog saved in "FO4D" resource named "SuperDialog"
void DisplaySuperDialog ()
{
PA_Dial4D dial;
char cancelOrValidate;
char lastVar[256];
// Create the dialog context
dial = PA_NewDialog();
// Open the FO4D resource
PA_OpenDialog(dial, "SuperDialog", 0);
// Loop
do {
cancelOrValidate = PA_ModalDialog( dial, lastVar );
if ( 0 == strcmp( lastVar, "aVar1" ) )
{
// user hits variable "aVar1"
/* . . . */
}
else if ( 0 == strcmp( lastVar, "aVar2" ) )
{
// user hits variable "aVar2"
/* . . . */
}
} while ( cancelOrValidate == 0 );
if ( cancelOrValidate == 1 )
{
// User validates the dialog
/* . . . */
}
else if ( cancelOrValidate == 2 )
{
// User cancels the dialog
/* . . . */
}
}
