| 552 | * DESCRIPTION: |
| 553 | * Yet another 'Gas Gauge Custom Control.' This control gives you |
| 554 | * a 'progress bar' class (named zYzGauge) for use in your applications. |
| 555 | * You can set the range, position, font, color, orientation, and 3d |
| 556 | * effect of the gauge by sending messages to the control. |
| 557 | * |
| 558 | * Before you can use this control, you MUST first export the window |
| 559 | * procedure for the control (or define it with the _export keyword): |
| 560 | * |
| 561 | * EXPORTS gaugeWndProc |
| 562 | * |
| 563 | * You then need initialize the class before you use it: |
| 564 | * |
| 565 | * if (!gaugeInit(hInstance)) |
| 566 | * die a horrible death |
| 567 | * else |
| 568 | * you are good to go |
| 569 | * |
| 570 | * The colors used by the control default to black and white if you |
| 571 | * are running on a mono-display. They default to blue and white |
| 572 | * if you are on a color display. You enable the 3D effect by setting |
| 573 | * the ZYZGS_3D style flag in the styles field of the control (like |
| 574 | * any other control). |
| 575 | * |
| 576 | * To select your own colors, you can send the ZYZG_SETFGCOLOR and |
| 577 | * ZYZG_SETBKCOLOR messages to set the foreground (percent done) and |
| 578 | * background (percent not done) colors. The lParam is the RGB() |
| 579 | * value--wParam is ignored. |
| 580 | * |
| 581 | * In all of the following ZYZG_??? messages, the arguments are |
| 582 | * WORDS. If you are setting parameters, the value is sent as |
| 583 | * the wParam (lParam is ignored). If you are getting parameters, |
| 584 | * the value is returned as a LONG and should be cast to a *signed* |
| 585 | * integer. |
| 586 | * |
| 587 | * To set the depth of the 3D effect (if enabled), you can send the |
| 588 | * ZYZG_SETBEZELFACE and ZYZG_SETWIDTH3D messages. The bezel face |
| 589 | * is the flat top on the 3D border--its color will be that of the |
| 590 | * button-face. The 3D width is the width of the bezel itself; inside |
| 591 | * and outside. The light color is white, the dark color is gray. |
| 592 | * Both widths *can* be zero--both default to 2 which looks to me. |
| 593 | * |
| 594 | * The range of the control can be set by sending the ZYZG_SETRANGE |
| 595 | * message to the control. It can be any integer from 1 to 32767. |
| 596 | * What this specifies is the number of pieces that create a whole. |
| 597 | * The default is 100. You can get the current range setting by |
| 598 | * sending the ZYZG_GETRANGE message to the control. |
| 599 | * |
| 600 | * The position (number of pieces out of the whole have been used) is |
| 601 | * set with the ZYZG_SETPOSITION message. It can be any integer from |
| 602 | * 0 to the current range setting of the control--it will be clipped |
| 603 | * if the position is out of bounds. The default position is 0. You |
| 604 | * can get the current position at any time with the ZYZG_GETPOSITION |
| 605 | * message. |
| 606 | * |
| 607 | * You can also set the range using a delta from the current range. |
| 608 | * This is done by sending the ZYZG_SETDELTAPOS message with wParam |
| 609 | * set to a _signed_ integer value within the range of the control. |
| 610 | * |
| 611 | * The font used for the percentage text can be set using the standard |
| 612 | * WM_SETFONT message. You can get the current font at any time with |
| 613 | * the WM_GETFONT message. |
| 614 | * |
| 615 | * The orientation can be left to right, right to left, bottom to top, |
| 616 | * or top to bottom. Whatever suits your needs. You set this by |
| 617 | * sending the ZYZG_ORIENTATION message to the control with one of |
| 618 | * the following values (default is ZYZG_ORIENT_LEFTTORIGHT): |
| 619 | * |
| 620 | * ZYZG_ORIENT_LEFTTORIGHT (0) |
| 621 | * ZYZG_ORIENT_RIGHTTOLEFT (1) |
| 622 | * ZYZG_ORIENT_BOTTOMTOTOP (2) |
| 623 | * ZYZG_ORIENT_TOPTOBOTTOM (3) |

| 960 | * The special control messages for the gauge control are: |
| 961 | * |
| 962 | * ZYZG_SETRANGE : Sets the range of the gauge. In other |
| 963 | * words, the number of parts that make a |
| 964 | * whole. |
| 965 | * |
| 966 | * ZYZG_GETRANGE : Returns the current range of the gauge. |
| 967 | * |
| 968 | * ZYZG_SETORIENTATION : Sets the orientation of the gauge. This |
| 969 | * can be one of the ZYZG_ORIENT_?? msgs. |
| 970 | * |
| 971 | * ZYZG_GETORIENTATION : Gets the current orientation of the |
| 972 | * gauge. |
| 973 | * |
| 974 | * ZYZG_SETPOSITION : Sets the current position of the gauge. |
| 975 | * In other words, how many pieces of the |
| 976 | * whole have been used. |
| 977 | * |
| 978 | * ZYZG_GETPOSITION : Gets the current position of the gauge. |
| 979 | * |
| 980 | * ZYZG_SETDELTAPOS : Sets the position of the gauge +/- the |
| 981 | * specified amount. |
| 982 | * |
| 983 | * ZYZG_SETFGCOLOR : Sets the foreground (percent done) color. |
| 984 | * |
| 985 | * ZYZG_GETFGCOLOR : Gets the foreground (percent done) color. |
| 986 | * |
| 987 | * ZYZG_SETBKCOLOR : Sets the background (percent not done) |
| 988 | * color. |
| 989 | * |
| 990 | * ZYZG_GETBKCOLOR : Gets the background (percent not done) |
| 991 | * color. |
| 992 | * |
| 993 | * WM_SETFONT : Sets the font to use for the percentage |
| 994 | * text of the gauge. |
| 995 | * |
| 996 | * WM_GETFONT : Gets the current font in use by the |
| 997 | * gauge. |
