This control gives you * a 'progress bar' class (named zYzGauge) for use in your applications. * You can set the range, position, font, color, orientation, and 3d * effect of the gauge by sending messages to the control. * * Before you can use this control, you MUST first export the window * procedure for the control (or define it with the _export keyword): * * EXPORTS gaugeWndProc * * You then need initialize the class before you use it: * * if (!gaugeInit(hInstance)) * die a horrible death * else * you are good to go * * The colors used by the control default to black and white if you * are running on a mono-display. They default to blue and white * if you are on a color display. You enable the 3D effect by setting * the ZYZGS_3D style flag in the styles field of the control (like * any other control). * * To select your own colors, you can send the ZYZG_SETFGCOLOR and * ZYZG_SETBKCOLOR messages to set the foreground (percent done) and * background (percent not done) colors. The lParam is the RGB() * value--wParam is ignored. * * In all of the following ZYZG_??? messages, the arguments are * WORDS. If you are setting parameters, the value is sent as * the wParam (lParam is ignored). If you are getting parameters, * the value is returned as a LONG and should be cast to a *signed* * integer. * * To set the depth of the 3D effect (if enabled), you can send the * ZYZG_SETBEZELFACE and ZYZG_SETWIDTH3D messages. The bezel face * is the flat top on the 3D border--its color will be that of the * button-face. The 3D width is the width of the bezel itself; inside * and outside. The light color is white, the dark color is gray. * Both widths *can* be zero--both default to 2 which looks to me. * * The range of the control can be set by sending the ZYZG_SETRANGE * message to the control. It can be any integer from 1 to 32767. * What this specifies is the number of pieces that create a whole. * The default is 100. You can get the current range setting by * sending the ZYZG_GETRANGE message to the control. * * The position (number of pieces out of the whole have been used) is * set with the ZYZG_SETPOSITION message. It can be any integer from * 0 to the current range setting of the control--it will be clipped * if the position is out of bounds. The default position is 0. You * can get the current position at any time with the ZYZG_GETPOSITION * message. * * You can also set the range using a delta from the current range. * This is done by sending the ZYZG_SETDELTAPOS message with wParam * set to a _signed_ integer value within the range of the control. * * The font used for the percentage text can be set using the standard * WM_SETFONT message. You can get the current font at any time with * the WM_GETFONT message. * * The orientation can be left to right, right to left, bottom to top, * or top to bottom. Whatever suits your needs. You set this by * sending the ZYZG_ORIENTATION message to the control with one of * the following values (default is ZYZG_ORIENT_LEFTTORIGHT): * * ZYZG_ORIENT_LEFTTORIGHT (0) * ZYZG_ORIENT_RIGHTTOLEFT (1) * ZYZG_ORIENT_BOTTOMTOTOP (2) * ZYZG_ORIENT_TOPTOBOTTOM (3) * * HISTORY: * 3/12/91 cjp put in this comment * 6/19/92 cjp touched it a bit * ** cjp */ // COPYRIGHT: // // (C) Copyright Microsoft Corp. 1992.

Its purpose is to handle * special messages for this custom control. * * The special control messages for the gauge control are: * * ZYZG_SETRANGE : Sets the range of the gauge. In other * words, the number of parts that make a * whole. * * ZYZG_GETRANGE : Returns the current range of the gauge. * * ZYZG_SETORIENTATION : Sets the orientation of the gauge. This * can be one of the ZYZG_ORIENT_?? msgs. * * ZYZG_GETORIENTATION : Gets the current orientation of the * gauge. * * ZYZG_SETPOSITION : Sets the current position of the gauge. * In other words, how many pieces of the * whole have been used. * * ZYZG_GETPOSITION : Gets the current position of the gauge. * * ZYZG_SETDELTAPOS : Sets the position of the gauge +/- the * specified amount. * * ZYZG_SETFGCOLOR : Sets the foreground (percent done) color. * * ZYZG_GETFGCOLOR : Gets the foreground (percent done) color. * * ZYZG_SETBKCOLOR : Sets the background (percent not done) * color. * * ZYZG_GETBKCOLOR : Gets the background (percent not done) * color. * * WM_SETFONT : Sets the font to use for the percentage * text of the gauge. * * WM_GETFONT : Gets the current font in use by the * gauge. * * NOTES: * ** cjp */ /* LRESULT FAR PASCAL */ LRESULT APIENTRY _EXPORT gaugeWndProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) { HFONT hFont; PAINTSTRUCT ps; PZYZGAUGE pgauge; RECT rc; // pgauge = (PZYZGAUGE)GetWindowWord(hwnd, ZYZG_WW_PZYZGAUGE); pgauge = (PZYZGAUGE)GetWindowLong(hwnd, ZYZG_WW_PZYZGAUGE); /* break to get DefWindowProc() */ switch (uMsg) { case WM_CREATE: /* need to allocate a control block */ // pgauge = (PZYZGAUGE)LocalAlloc(LPTR, sizeof(ZYZGAUGE)); pgauge = (PZYZGAUGE)malloc(sizeof(ZYZGAUGE)); if (!pgauge) return (0L); /* hang on to this control block */ // SetWindowWord(hwnd, ZYZG_WW_PZYZGAUGE, (WORD)pgauge); SetWindowLong(hwnd, ZYZG_WW_PZYZGAUGE, (LONG)pgauge); /* fill control block with defaults */ pgauge->wRange = ZYZG_DEF_RANGE; pgauge->wPosition = ZYZG_DEF_POSITION; pgauge->wOrientation = ZYZG_DEF_ORIENTATION; pgauge->wWidth3D = ZYZG_DEF_WIDTH3D; pgauge->wWidthBezelFace = ZYZG_DEF_BEZELFACE; pgauge->rgbTextColor = rgbDefTextColor; pgauge->rgbBkColor = rgbDefBkColor; /* use system font */ SendMessage(hwnd, WM_SETFONT, (WPARAM)NULL, 0L); /* go to DefWindowProc() to finish the job */ break; case WM_DESTROY: /* get rid of the control's memory */ if (pgauge) // LocalFree((HANDLE)pgauge); free(pgauge); break; case ZYZG_GETPOSITION: return (pgauge->wPosition); case ZYZG_GETRANGE: return (pgauge->wRange); case ZYZG_GETORIENTATION: return (pgauge->wOrientation); case ZYZG_GETWIDTH3D: return (pgauge->wWidth3D); case ZYZG_GETBEZELFACE: return (pgauge->wWidthBezelFace); case ZYZG_GETBKCOLOR: return (pgauge->rgbTextColor); case ZYZG_GETFGCOLOR: return (pgauge->rgbBkColor); case ZYZG_SETBKCOLOR: pgauge->rgbBkColor = lParam; return (0L); case ZYZG_SETFGCOLOR: pgauge->rgbTextColor = lParam; return (0L); case ZYZG_SETPOSITION: pgauge->wPosition = wParam; zyzgForceRepaint: GetClientRect(hwnd, &rc); if ((GetWindowLong(hwnd, GWL_STYLE) & ZYZGS_3D) && fSupport3D) { wParam = (2 * pgauge->wWidth3D) + pgauge->wWidthBezelFace + 2; } else wParam = 1; InflateRect(&rc, ~(wParam), ~(wParam)); InvalidateRect(hwnd, &rc, FALSE); UpdateWindow(hwnd); return (0L); case ZYZG_SETRANGE: pgauge->wRange = wParam; goto zyzgForceRepaint; case ZYZG_SETORIENTATION: pgauge->wOrientation = wParam; goto zyzgForceRepaint; case ZYZG_SETWIDTH3D: pgauge->wWidth3D = wParam; zyzgForceRepaint3D: InvalidateRect(hwnd, NULL, FALSE); UpdateWindow(hwnd); return (0L); case ZYZG_SETBEZELFACE: pgauge->wWidthBezelFace = wParam; goto zyzgForceRepaint3D; case ZYZG_SETDELTAPOS: /* Watcom doesn't like the following line so removing typecasts */ /* (int)pgauge->wPosition += (int)wParam; */ pgauge->wPosition += wParam; goto zyzgForceRepaint; case WM_PAINT: BeginPaint(hwnd, &ps); gaugePaint(hwnd, ps.hdc); EndPaint(hwnd, &ps); return (0L); case WM_GETFONT: hFont = pgauge->hFont; /* if system font, then return NULL handle */ return (long)((hFont == GetStockObject(SYSTEM_FONT)) ?
