/* Defines for WinOldAppHackoMatic flags which win386 oldapp can send to us.
* These are kept in user's global variable winOldAppHackoMaticFlags */
/*
* WOAHACK_CHECKALTKEYSTATE * * This is sent from WinOldAp to USER when the user has just pressed * Alt+Space. When the user does that, keyboard focus shifts from * the DOS box to Windows. This is particularly weird because the * focus is changing while the user has a key down. The message is * sent to USER to let it know that the Alt key may be in a funky * state right now. * * The value of this must be a power of two because it is used * in the winOldAppHackoMaticFlags variable as a bitmask. * * WOAHACK_IGNOREALTKEYDOWN * * This is used internally by USER to keep track of the Alt key * state, triggered by the WOAHACK_CHECKALTKEYSTATE message. * * The value of this must be a power of two because it is used * in the winOldAppHackoMaticFlags variable as a bitmask. * * WOAHACK_DISABLEREPAINTSCREEN * * This is sent from WinOldAp to USER when the user has initiated * an Alt+Tab sequence from a fullscreen VM. This causes USER to * defer the RepaintScreen that will be sent by the display driver. * This speeds up Alt+Tab'ing. When the Alt+Tab is complete, * if the user selected another fullscreen DOS box, USER will ignore * the RepaintScreen altogether, since it's about to lose the * display focus anyway. In all other cases, the RepaintScreen will * be performed once the Alt+Tab is complete. * * WOAHACK_LOSINGDISPLAYFOCUS * WOAHACK_GAININGDISPLAYFOCUS * * These messages are sent from WinOldAp to USER when the display * focus is changing. The WOAHACK_LOSINGDISPLAYFOCUS message is * sent *before* Windows is about to lose focus, and the * WOAHACK_GAININGDISPLAYFOCUS is sent *after* Windows has regained * the display focus. * * WinOldAp sends these messages whenever it is about to set the * VM focus. It doesn't check if the message is a repeat of a * previous message. (So, for example, USER may receive three * copies of WOAHACK_GAININGDISPLAYFOCUS.) USER maintains an * internal variable to keep track of whether each receipt of the * message is a change in the focus or just a redundant notification. * * USER uses these messages to turn off the timer that is normally * used to trigger the mouse drawing code in the display driver * while Windows does not have the display focus, and to turn the * timer back on once Windows gets the display back. * * This is needed to make sure the display driver is otherwise * quiet when the int 2F is dispatched from the VDD to notify the * display driver that the focus has changed. Not doing this * opens the possibility of re-entrancy in the display driver. * * WOAHACK_IMAWINOLDAPSORTOFGUY * * WinOldAp needs to call this API once with this flag set so that * USER can mark winoldap's queue as being winoldap. USER needs * to know that a particular queue is winoldap for several reasons * having to do with task switching and priorities. */#define WOAHACK_CHECKALTKEYSTATE 1

/*
* These property bits are stored in the flWinOldAp property of * WinOldAp's main window. They are provided so that USER and other * applications can query the state of the DOS box. * * These properties are read-only. Changing them will cause Windows * to get confused. * * woapropIsWinOldAp * * This bit is always set. * * woapropFullscreen * * Set if this a fullscreen DOS box rather than a windowed DOS box. * Note that this bit is set even if WinOldAp does not have focus. * (E.g., when iconic.) Its purpose is to indicate what the state * of the DOS box would be *if* it were to be activated. * * woapropActive * * Set if WinOldAp is active. Note that one cannot merely * check IsIconic(hwnd) because fullscreen DOS boxes are always * iconic. * * None of the other bits are used, although names for some of them * have been chosen. This does not represent any commitment to use * them for the purpose the name suggests. * * Other properties we may think of adding... * * hvm * * This extended property contains the 32-bit VM handle. * * hprop * * This property contains the property handle being used * by the DOS box. (For utilities which want to be able * to modify the properties of a running DOS box, perhaps.) * */
