Windows — OpenWindow, IDCMP, WA_ Tags

Overview

A Window is a rectangular region on a Screen where an application renders and receives input. Windows are managed by Intuition and provide title bars, borders, close/zoom/depth gadgets, sizing, and IDCMP message delivery.

Opening a Window (OS 2.0+)

struct Window *win = OpenWindowTags(NULL,
    WA_Left,        50,
    WA_Top,         30,
    WA_Width,       400,
    WA_Height,      200,
    WA_Title,       "My Window",
    WA_Flags,       WFLG_CLOSEGADGET | WFLG_DRAGBAR | WFLG_DEPTHGADGET |
                    WFLG_SIZEGADGET | WFLG_ACTIVATE | WFLG_GIMMEZEROZERO,
    WA_IDCMP,       IDCMP_CLOSEWINDOW | IDCMP_MOUSEBUTTONS | IDCMP_VANILLAKEY,
    WA_CustomScreen, myScreen,
    TAG_DONE);

Event Loop

BOOL running = TRUE;
while (running) {
    WaitPort(win->UserPort);
    struct IntuiMessage *imsg;
    while ((imsg = (struct IntuiMessage *)GetMsg(win->UserPort))) {
        switch (imsg->Class) {
            case IDCMP_CLOSEWINDOW:
                running = FALSE;
                break;
            case IDCMP_VANILLAKEY:
                Printf("Key: %lc\n", imsg->Code);
                break;
        }
        ReplyMsg((struct Message *)imsg);
    }
}
CloseWindow(win);
