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.
