Hello Chris,
I have a simple example of Popuup: I use Prc-tools + VFDIDE.
In this project, cmbTeste is the Popup Trigger, and the lstTeste is the
List linked with cmbTeste.
In the exemple I show the contents of array MatCombo.
//ListPtr PtrCmbTeste;
char *MatCombo[50];
ListPtr PlstTeste;
ControlPtr PcmbTeste;
static int frmPrincHdlr(EventType *e)
{
// This function is set in Event Loop with FrmSetEventHandler function
FormPtr frm;
CharPtr strAux;
switch(e->eType)
{
case frmOpenEvent:
MatCombo[0] = "Combo 1";
MatCombo[1] = "Combo 2";
MatCombo[2] = "Combo 3";
frm = FrmGetActiveForm();
// Set pointers
PlstPgm =FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, lstPgm));
PcmbTeste =FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, cmbTeste));
// Link array to popup
LstSetListChoices(PlstPgm, MatCombo, 3);
FrmDrawForm(frm);
return 1; /* event handled */
case ctlSelectEvent:
switch (e->data.ctlEnter.controlID)
{
case lstTeste:
// The user clicked in Popup Trigger
LstPopupList(PlstTeste);
strAux = LstGetSelectionText(PlstTeste,0);
// Change the label
CtlSetLabel(PcmbTeste,strAux);
return 1;
}
case nilEvent:
return 0;
default:
}
return 0; /* Event not handled */
}
If you have any doubts, email me.
