Easy Pop-Up Menus for System 6! Rockwell Schrock <rockwell@schrock.me> https://schrockwell.com This library makes it more convenient to add pop-up menus to System 6 applications. In System 7 and later, you can define a control with procID 1008, but prior to that, some hand-holding is required to achieve the expected control behavior. These functions take care of the grunt work for System 6: - drawing the control - opening the menu with PopUpMenuSelect() - storing the selected item To use it, you only need to provide: - a WindowPtr for the containing window - a Rect for the bounds of the menu control - a MenuHandle to the menu - styling options ...and add hooks in three places: 1. Initialization 2. Event loop 3. Window update See PopUp.h for more documentation and styling options. === Example === // 1. Initialization PopUpPtr gPopup; // <--- void WindowInit() { WindowPtr window; Rect windRect; Rect popupRect = { 10, 10, 29, 120 }; // <--- recommend 19px height MenuHandle menu; window = GetNewWindow(kBaseResID, nil, kMoveToFront); menu = GetMenu(kPopUpMenuResourceID); gPopup = CreatePopUp(window, &popupRect, menu, kPopUpStyleDefault); // <--- SetPort(window); ShowWindow(window); } // 2. Event loop void DoEvent(EventRecord *eventPtr) { if (HandlePopUpEvent(gPopup, eventPtr)) // <--- { // gPopup->item contains the newly-selected item return; } // ...rest of event handlers... } // 3. Window updates void DoUpdate(EventRecord *eventPtr) { WindowPtr window = (WindowPtr)eventPtr->message; BeginUpdate(window); DrawPopUp(gPopup); // <--- EndUpdate(window); } |
