Notes

The IupMessageDlg is a native pre-defined dialog not altered by IupSetLanguage.

To show the dialog, use function IupPopup. In Lua, use the popup function.

The dialog is mapped only inside IupPopup, IupMap does nothing.

In Windows the position (x,y) used in IupPopup is ignored and the dialog is always centered on screen.

The IupMessage function simply creates and popup a IupMessageDlg.

In Windows each different dialog type is always associated with a different beep sound.

Examples

Ihandle* dlg = IupMessageDlg();

IupSetAttribute(dlg, "DIALOGTYPE", "WARNING");
IupSetAttribute(dlg, "TITLE", "IupMessageDlg Test");
IupSetAttribute(dlg, "BUTTONS", "OKCANCEL");
IupSetAttribute(dlg, "VALUE", "Message Text\nSecond Line");
IupSetCallback(dlg, "HELP_CB", (Icallback)help_cb);

IupPopup(dlg, IUP_CURRENT, IUP_CURRENT);

printf("BUTTONRESPONSE(%s)\n", IupGetAttribute(dlg, "BUTTONRESPONSE"));

IupDestroy(dlg);
