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 *
22 *@@added V0.9.9 (2001-04-01) [umoeller]

1279 * sizes of those controls that want to depend on
1280 * others.
1281 *
1282 * -- PROCESS_3_CALC_FINAL_TABLE_SIZES: since the table
1283 * and row sizes might have changed during
1284 * PROCESS_2_CALC_SIZES_FROM_TABLES, we need to re-run
1285 * to re-calculate the size of all rows and tables.
1286 * After this first call, we know _all_ the sizes
1287 * and can then calculate the positions.
1288 *
1289 * -- PROCESS_4_CALC_POSITIONS: calculates the positions
1290 * based on the sizes calculated before.
1291 *
1292 * -- PROCESS_5_CREATE_CONTROLS: creates the controls with the
1293 * positions and sizes calculated before.
1294 *
1295 * The second trick is the precondition that tables may
1296 * nest by allowing another table definition in a column.
1297 * This way we can recurse from ProcessColumn back into
1298 * ProcessTable and thus know the size and position of a
1299 * nested table column just as if it were a regular control.

1792 * the control _sizes_, and all positions are computed
1793 * automatically here. Even better, for many controls,
1794 * auto-sizing is supported according to the control's
1795 * text (e.g. for statics and checkboxes). In a way,
1796 * this is a bit similar to HTML tables.
1797 *
1798 * A regular standard dialog would use something like
1799 *
1800 + FCF_TITLEBAR | FCF_SYSMENU | FCF_DLGBORDER | FCF_NOBYTEALIGN
1801 *
1802 * for flCreateFlags. To make the dlg sizeable, specify
1803 * FCF_SIZEBORDER instead of FCF_DLGBORDER.
1804 *
1805 * <B>Usage:</B>
1806 *
1807 * Like WinLoadDlg, this creates a standard WC_FRAME and
1808 * subclasses it with fnwpMyDlgProc. It then sends WM_INITDLG
1809 * to the dialog with pCreateParams in mp2.
1810 *
1811 * If this func returns no error, you can then use
1812 * WinProcessDlg with the newly created dialog as usual. In
1813 * your dlg proc, use WinDefDlgProc as usual.
1814 *
1815 * There is NO run-time overhead for either code or memory
1816 * after dialog creation; after this function returns, the
1817 * dialog is a standard dialog as if loaded from WinLoadDlg.
1818 * The array of DLGHITEM structures defines how the
1819 * dialog is set up. All this is ONLY used by this function
1820 * and NOT needed after the dialog has been created.
1821 *
1822 * In DLGHITEM, the "Type" field determines what this
1823 * structure defines. A number of handy macros have been
1824 * defined to make this easier and to provide type-checking
1825 * at compile time. See dialog.h for more.
1826 *
1827 * Essentially, such a dialog item operates similarly to
1828 * HTML tables. There are rows and columns in the table,
1829 * and each control which is specified must be a column
1830 * in some table. Tables may also nest (see below).
1831 *
1832 * The DLGHITEM macros are:
1833 *
1834 * -- START_TABLE starts a new table. The tables may nest,
1835 * but must each be properly terminated with END_TABLE.
1836 *
1837 * -- START_GROUP_TABLE(pDef) starts a group. This
1838 * behaves exacly like START_TABLE, but in addition,
1839 * it produces a static group control around the table.
1840 * Useful for group boxes. pDef must point to a
1841 * CONTROLDEF describing the control to be used for
1842 * the group (usually a WC_STATIC with SS_GROUP style),
1843 * whose size parameter is ignored.
1844 *
1845 * As with START_TABLE, START_GROUP_TABLE must be
1846 * terminated with END_TABLE.
1847 *
1848 * -- START_ROW(fl) starts a new row in a table (regular
1849 * or group). This must also be the first item after
1850 * the (group) table tag.
1851 *
1852 * fl specifies formatting flags for the row. This
1853 * can be one of ROW_VALIGN_BOTTOM, ROW_VALIGN_CENTER,
1854 * ROW_VALIGN_TOP and affects all items in the row.
1855 *
1856 * -- CONTROL_DEF(pDef) defines a control in a table row.
1857 * pDef must point to a CONTROLDEF structure.
1858 *
1859 * Again, there is is NO information in CONTROLDEF
1860 * about a control's _position_. Instead, the structure
1861 * only contains the _size_ of the control. All
1862 * positions are computed by this function, depending
1863 * on the sizes of the controls and their nesting within
1864 * the various tables.
1865 *
1866 * If you specify SZL_AUTOSIZE with either cx or cy
1867 * or both, the size of the control is even computed
1868 * automatically. Presently, this only works for statics
1869 * with SS_TEXT, SS_ICON, and SS_BITMAP, push buttons,
1870 * and radio and check boxes.
1871 *
1872 * Unless separated with START_ROW items, subsequent
1873 * control items will be considered to be in the same
1874 * row (== positioned next to each other).
1875 *
1876 * There are a few rules, whose violation will produce
1877 * an error:
1878 *
1879 * -- The entire array must be enclosed in a table
1880 * (the "root" table).
1881 *
1882 * -- After START_TABLE or START_GROUP_TABLE, there must
1883 * always be a START_ROW first.
1884 *
1885 * While it is possible to set up the CONTROLDEFs manually
1886 * as static structures, I recommend using the bunch of
1887 * other macros that were defined in dialog.h for this.
1888 * For example, you can use CONTROLDEF_PUSHBUTTON to create
1889 * a push button, and many more.
1890 *
1891 * To create a dialog, set up arrays like the following:
1892 *
1893 + // control definitions referenced by DlgTemplate:
1894 + CONTROLDEF
1895 + (1) GroupDef = CONTROLDEF_GROUP("Group",
1896 + -1, // ID
1897 + SZL_AUTOSIZE,
1898 + SZL_AUTOSIZE),
1899 + (2) CnrDef = CONTROLDEF_CONTAINER(-1, // ID,
1900 + 50,
1901 + 50),
1902 + (3) Static = CONTROLDEF_TEXT("Static below cnr",
1903 + -1, // ID
1904 + SZL_AUTOSIZE,
1905 + SZL_AUTOSIZE),
1906 + (4) OKButton = CONTROLDEF_DEFPUSHBUTTON("~OK",
1907 + DID_OK,
1908 + SZL_AUTOSIZE,
1909 + SZL_AUTOSIZE),
1910 + (5) CancelButton = CONTROLDEF_PUSHBUTTON("~Cancel",
1911 + DID_CANCEL,
1912 + SZL_AUTOSIZE,
1913 + SZL_AUTOSIZE);
1914 +
1915 + DLGHITEM DlgTemplate[] =
1916 + {
1917 + START_TABLE, // root table, required
1918 + START_ROW(0), // row 1 in the root table, required
1919 + // create group on top
1920 + (1) START_GROUP_TABLE(&Group),
1921 + START_ROW(0),
1922 + (2) CONTROL_DEF(&CnrDef),
1923 + START_ROW(0),
1924 + (3) CONTROL_DEF(&Static),
1925 + END_TABLE, // end of group
1926 + START_ROW(0), // row 2 in the root table
1927 + // two buttons next to each other
1928 + (4) CONTROL_DEF(&OKButton),
1929 + (5) CONTROL_DEF(&CancelButton),
1930 + END_TABLE
1931 + }
1932 *
1933 * This will produce a dlg like this:

2337 * A dialog array is simply an array of
2338 * DLGHITEM structures, as you would normally
2339 * define them statically in the source.
2340 * However, there are situations where you
2341 * might want to leave out certain controls
2342 * depending on certain conditions, which
2343 * can be difficult with static arrays.
2344 *
2345 * As a result, these "array" functions have
2346 * been added to allow for adding static
2347 * DLGHITEM subarrays to a dynamic array in
2348 * memory, which can then be passed to the
2349 * formatter.
2350 *
2351 * Usage:
2352 *
2353 * 1) Call this function with the maximum
2354 * amount of DLGHITEM's that will need
2355 * to be allocated in cMaxItems. Set this
2356 * to the total sum of all DLGHITEM's
2357 * in all the subarrays.
2358 *
2359 * 2) For each of the subarrays, call
2360 * dlghAppendToArray to have the subarray
2361 * appended to the dialog array.
2362 * After each call, DLGARRAY.cDlgItemsNow
2363 * will contain the actual total count of
2364 * DLGHITEM's that were added.
2365 *
2366 * 3) Call dlghCreateDialog with the dialog
2367 * array.
2368 *
2369 * 4) Call dlghFreeArray.
2370 *
2371 * Sort of like this (error checking omitted):
