Dialog returned values [message #2448]

I have a dialog with three buttons : "Overwrite", "Append" and "Cancel". The code to invoke the dlg is as follow:

ConfirmOverwriteDlg confirmDlg;
int dlgId = confirmDlg.Execute();
switch (dlgId) {
case 100:
PromptOK("Overwrite");
break;  
case 101:
PromptOK("Append");	
break;
default:
PromptOK("Cancel");
}

100 and 101 are assigned to the "Overwrite" and "Append" buttons in the lay file respectively. But the above does not work. How do I wire the button to the ID? Thanks

You should have your button set as rather an acceptor, rejector or breaker then you can associate and ID with the button. I have modified the Layout ref. coded and added a button ("help").
The code looks like:

GUI_APP_MAIN
{
	WithDialogLayout<TopWindow> dlg;
	CtrlLayoutOKCancel(dlg, "Enter a number");
	dlg.Acceptor(dlg.help, IDHELP);
	dlg.number <<= 10;
	for(;;)
		switch(dlg.Execute()) {
		case IDOK:
			PromptOK(AsString(~dlg.number));
			break;
		case IDCANCEL:
			return;
		case IDHELP:
			PromptOK("Help me!");
			break;
		}
}

lay file:

LAYOUT(DialogLayout, 312, 168)
	ITEM(Label, dv___0, SetLabel(t_("A number")).LeftPosZ(8, 56).TopPosZ(8, 19))
	ITEM(EditIntSpin, number, LeftPosZ(64, 76).TopPosZ(8, 19))
	ITEM(Button, cancel, SetLabel(t_("Cancel")).LeftPosZ(76, 64).TopPosZ(36, 24))
	ITEM(Button, help, SetLabel(t_("Help")).LeftPosZ(32, 116).TopPosZ(96, 32))
	ITEM(Button, ok, SetLabel(t_("OK")).LeftPosZ(8, 64).TopPosZ(36, 24))
END_LAYOUT

You should take a look at the code of CtrlLayoutOKCancel in TopWindow.h.
