3 *@@sourcefile dialog.c:
4 * contains PM helper functions to create and
5 * auto-format dialogs from control arrays in memory.
6 *
7 * See dlghCreateDlg for details.
8 *
9 * In addition, this has dlghMessageBox (a WinMessageBox
10 * replacement) and some helper functions for simulating
11 * dialog behavior in regular window procs (see
12 * dlghSetPrevFocus and others).
13 *
14 * Usage: All PM programs.
15 *
16 * Function prefixes (new with V0.81):
17 * -- dlg* Dialog functions
18 *
19 * Note: Version numbering in this file relates to XWorkplace version
20 * numbering.
21 *

1524/*
1525 *@@ dlghCreateDlg:
1526 * replacement for WinCreateDlg/WinLoadDlg for creating a
1527 * dialog from a settings array in memory, which is
1528 * formatted automatically.
1529 *
1530 * This does NOT use regular dialog templates from
1531 * module resources. Instead, you pass in an array
1532 * of DLGHITEM structures, which define the controls
1533 * and how they are to be formatted.
1534 *
1535 * The main advantage compared to dialog resources is
1536 * that with this function, you will never have to
1537 * define control _positions_. Instead, you only specify
1538 * the control _sizes_, and all positions are computed
1539 * automatically here. Even better, for many controls,
1540 * auto-sizing is supported according to the control's
1541 * text (e.g. for statics and checkboxes).
1542 *
1543 * A regular standard dialog would use something like
1544 *
1545 + FCF_TITLEBAR | FCF_SYSMENU | FCF_DLGBORDER | FCF_NOBYTEALIGN
1546 *
1547 * for flCreateFlags. To make the dlg sizeable, specify
1548 * FCF_SIZEBORDER instead of FCF_DLGBORDER.
1549 *
1550 * <B>Usage:</B>
1551 *
1552 * Like WinLoadDlg, this creates a standard WC_FRAME and
1553 * subclasses it with fnwpMyDlgProc. It then sends WM_INITDLG
1554 * to the dialog with pCreateParams in mp2.
1555 *
1556 * If this func returns no error, you can then use
1557 * WinProcessDlg with the newly created dialog as usual. In
1558 * your dlg proc, use WinDefDlgProc as usual.
1559 *
1560 * There is NO run-time overhead for either code or memory
1561 * after dialog creation; after this function returns, the
1562 * dialog is a standard dialog as if loaded from WinLoadDlg.
1563 * The array of DLGHITEM structures defines how the
1564 * dialog is set up. All this is ONLY used by this function
1565 * and NOT needed after the dialog has been created.
1566 *
1567 * In DLGHITEM, the "Type" field determines what this
1568 * structure defines. A number of handy macros have been
1569 * defined to make this easier and to provide type-checking
1570 * at compile time. See dialog.h for more.
1571 *
1572 * Essentially, such a dialog item operates similarly to
1573 * HTML tables. There are rows and columns in the table,
1574 * and each control which is specified must be a column
1575 * in some table. Tables may also nest (see below).
1576 *
1577 * The macros are:
1578 *
1579 * -- START_TABLE starts a new table. The tables may nest,
1580 * but must each be properly terminated with END_TABLE.
1581 *
1582 * -- START_GROUP_TABLE(pDef) starts a group. This
1583 * behaves exacly like START_TABLE, but in addition,
1584 * it produces a static group control around the table.
1585 * Useful for group boxes. pDef must point to a
1586 * _CONTROLDEF describing the control to be used for
1587 * the group (usually a WC_STATIC with SS_GROUP style),
1588 * whose size parameter is ignored.
1589 *
1590 * As with START_TABLE, START_GROUP_TABLE must be
1591 * terminated with END_TABLE.
1592 *
1593 * -- START_ROW(fl) starts a new row in a table (regular
1594 * or group). This must also be the first item after
1595 * the (group) table tag.
1596 *
1597 * fl specifies formatting flags for the row. This
1598 * can be one of ROW_VALIGN_BOTTOM, ROW_VALIGN_CENTER,
1599 * ROW_VALIGN_TOP and affects all items in the row.
1600 *
1601 * -- CONTROL_DEF(pDef) defines a control in a table row.
1602 * pDef must point to a CONTROLDEF structure.
1603 *
1604 * Again, there is is NO information in
1605 * CONTROLDEF about a control's _position_.
1606 * Instead, the structure only contains the _size_
1607 * of the control. All positions are computed by
1608 * this function, depending on the sizes of the
1609 * controls and their nesting within the various tables.
1610 *
1611 * If you specify SZL_AUTOSIZE, the size of the
1612 * control is even computed automatically. Presently,
1613 * this only works for statics with SS_TEXT, SS_ICON,
1614 * and SS_BITMAP.
1615 *
1616 * Unless separated with START_ROW items, subsequent
1617 * control items will be considered to be in the same
1618 * row (== positioned next to each other).
1619 *
1620 * There are a few rules, whose violation will produce
1621 * an error:
1622 *
1623 * -- The entire array must be enclosed in a table
1624 * (the "root" table).
1625 *
1626 * -- After START_TABLE or START_GROUP_TABLE, there must
1627 * always be a START_ROW first.
1628 *
1629 * To create a dialog, set up arrays like the following:
1630 *
1631 + // control definitions referenced by DlgTemplate:
1632 + CONTROLDEF
1633 + (1) GroupDef = {
1634 + WC_STATIC, "", ....,
1635 + { 0, 0 }, // size, ignored for groups
1636 + 5 // spacing
1637 + },
1638 + (2) CnrDef = {
1639 + WC_CONTAINER, "", ....,
1640 + { 50, 50 }, // size
1641 + 5 // spacing
1642 + },
1643 + (3) Static = {
1644 + WC_STATIC, "Static below cnr", ...,
1645 + { SZL_AUTOSIZE, SZL_AUTOSIZE }, // size
1646 + 5 // spacing
1647 + },
1648 + (4) OKButton = {
1649 + WC_STATIC, "~OK", ...,
1650 + { 100, 30 }, // size
1651 + 5 // spacing
1652 + },
1653 + (5) CancelButton = {
1654 + WC_STATIC, "~Cancel", ...,
1655 + { 100, 30 }, // size
1656 + 5 // spacing
1657 + };
1658 +
1659 + DLGHITEM DlgTemplate[] =
1660 + {
1661 + START_TABLE, // root table, required
1662 + START_ROW(0), // row 1 in the root table, required
1663 + // create group on top
1664 + (1) START_GROUP_TABLE(&Group),
1665 + START_ROW(0),
1666 + (2) CONTROL_DEF(&CnrDef),
1667 + START_ROW(0),
1668 + (3) CONTROL_DEF(&Static),
1669 + END_TABLE, // end of group
1670 + START_ROW(0), // row 2 in the root table
1671 + // two buttons next to each other
1672 + (4) CONTROL_DEF(&OKButton),
1673 + (5) CONTROL_DEF(&CancelButton),
1674 + END_TABLE
1675 + }

2055 *@@ dlghCreateArray:
2056 * creates a "dialog array" for dynamically
2057 * building a dialog template in memory.
2058 *
2059 * A dialog array is simply an array of
2060 * DLGHITEM structures, as you would normally
2061 * define them statically in the source.
2062 * However, there are situations where you
2063 * might want to leave out certain controls
2064 * depending on certain conditions, which
2065 * can be difficult with static arrays.
2066 *
2067 * As a result, these "array" functions have
2068 * been added to allow for adding static
2069 * DLGHITEM subarrays to a dynamic array in
2070 * memory, which can then be passed to the
2071 * formatter.
2072 *
2073 * Usage:
2074 *
2075 * 1) Call this function with the maximum
2076 * amount of DLGHITEM's that will need
2077 * to be allocated in cMaxItems. Set this
2078 * to the total sum of all DLGHITEM's
2079 * in all the subarrays.
2080 *
2081 * 2) For each of the subarrays, call
2082 * dlghAppendToArray to have the subarray
2083 * appended to the dialog array.
2084 * After each call, DLGARRAY.cDlgItemsNow
2085 * will contain the actual total count of
2086 * DLGHITEM's that were added.
2087 *
2088 * 3) Call dlghCreateDialog with the dialog
2089 * array.
2090 *
2091 * 4) Call dlghFreeArray.
2092 *
2093 * Sort of like this (error checking omitted):
