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]

966 *@@ dlghCreateDlg:
967 * replacement for WinCreateDlg/WinLoadDlg for creating a
968 * dialog from a settings array in memory, which is
969 * formatted automatically.
970 *
971 * This does NOT use regular dialog templates from
972 * module resources. Instead, you pass in an array
973 * of _DLGHITEM structures, which define the controls
974 * and how they are to be formatted.
975 *
976 * A regular standard dialog would use something like
977 *
978 + FCF_TITLEBAR | FCF_SYSMENU | FCF_DLGBORDER | FCF_NOBYTEALIGN
979 *
980 * for flCreateFlags. To make the dlg sizeable, specify
981 * FCF_SIZEBORDER instead of FCF_DLGBORDER.
982 *
983 * <B>Usage:</B>
984 *
985 * Like WinLoadDlg, this creates a standard WC_FRAME and
986 * subclasses it with fnwpMyDlgProc. It then sends WM_INITDLG
987 * to the dialog with pCreateParams in mp2.
988 *
989 * If this func returns no error, you can then use
990 * WinProcessDlg with the newly created dialog as usual. In
991 * your dlg proc, use WinDefDlgProc as usual.
992 *
993 * There is NO run-time overhead after creation; after this
994 * function returns, the dialog is a standard dialog as if
995 * loaded from WinLoadDlg.
996 *
997 * The array of _DLGHITEM structures defines how the
998 * dialog is set up. All this is ONLY used by this function
999 * and NOT needed after the dialog has been created.
1000 *
1001 * In _DLGHITEM, the "Type" field determines what this
1002 * structure defines. A number of handy macros have been
1003 * defined to make this easier and to provide type-checking
1004 * at compile time.
1005 *
1006 * Essentially, such a dialog item operates similarly to
1007 * HTML tables. There are rows and columns in the table,
1008 * and each control which is specified must be a column
1009 * in some table. Tables may also nest (see below).
1010 *
1011 * The macros are:
1012 *
1013 * -- START_TABLE starts a new table. The tables may nest,
1014 * but must each be properly terminated with END_TABLE.
1015 *
1016 * -- START_GROUP_TABLE(pDef) starts a group. This
1017 * behaves exacly like START_TABLE, but in addition,
1018 * it produces a static group control around the table.
1019 * Useful for group boxes. pDef must point to a
1020 * _CONTROLDEF describing the control to be used for
1021 * the group (usually a WC_STATIC with SS_GROUP style),
1022 * whose size parameter is ignored.
1023 *
1024 * As with START_TABLE, START_GROUP_TABLE must be
1025 * terminated with END_TABLE.
1026 *
1027 * -- START_ROW(fl) starts a new row in a table (regular
1028 * or group). This must also be the first item after
1029 * the (group) table tag.
1030 *
1031 * fl specifies formatting flags for the row. This
1032 * can be one of ROW_VALIGN_BOTTOM, ROW_VALIGN_CENTER,
1033 * ROW_VALIGN_TOP and affects all items in the control.
1034 *
1035 * -- CONTROL_DEF(pDef) defines a control in a table row.
1036 * pDef must point to a _CONTROLDEF structure.
1037 *
1038 * The main difference (and advantage) of this
1039 * function is that there is NO information in
1040 * _CONTROLDEF about a control's _position_.
1041 * Instead, the structure only contains the _size_
1042 * of the control. All positions are computed by
1043 * this function, depending on the sizes of the
1044 * controls and their nesting within the various tables.
1045 *
1046 * If you specify SZL_AUTOSIZE, the size of the
1047 * control is even computed automatically. Presently,
1048 * this only works for statics with SS_TEXT, SS_ICON,
1049 * and SS_BITMAP.
1050 *
1051 * Unless separated with START_ROW items, subsequent
1052 * control items will be considered to be in the same
1053 * row (== positioned next to each other).
1054 *
1055 * There are a few rules, whose violation will produce
1056 * an error:
1057 *
1058 * -- The entire array must be enclosed in a table
1059 * (the "root" table).
1060 *
1061 * -- After START_TABLE or START_GROUP_TABLE, there must
1062 * always be a START_ROW first.
1063 *
1064 * To create a dialog, set up arrays like the following:
1065 *
1066 + // control definitions referenced by DlgTemplate:
1067 + CONTROLDEF
1068 + (1) GroupDef = {
1069 + WC_STATIC, "", ....,
1070 + { 0, 0 }, // size, ignored for groups
1071 + 5 // spacing
1072 + },
1073 + (2) CnrDef = {
1074 + WC_CONTAINER, "", ....,
1075 + { 50, 50 }, // size
1076 + 5 // spacing
1077 + },
1078 + (3) Static = {
1079 + WC_STATIC, "Static below cnr", ...,
1080 + { SZL_AUTOSIZE, SZL_AUTOSIZE }, // size
1081 + 5 // spacing
1082 + },
1083 + (4) OKButton = {
1084 + WC_STATIC, "~OK", ...,
1085 + { 100, 30 }, // size
1086 + 5 // spacing
1087 + },
1088 + (5) CancelButton = {
1089 + WC_STATIC, "~Cancel", ...,
1090 + { 100, 30 }, // size
1091 + 5 // spacing
1092 + };
1093 +
1094 + DLGHITEM DlgTemplate[] =
1095 + {
1096 + START_TABLE, // root table, required
1097 + START_ROW(0), // row 1 in the root table, required
1098 + // create group on top
1099 + (1) START_GROUP_TABLE(&Group),
1100 + START_ROW(0),
1101 + (2) CONTROL_DEF(&CnrDef),
1102 + START_ROW(0),
1103 + (3) CONTROL_DEF(&Static),
1104 + END_TABLE, // end of group
1105 + START_ROW(0), // row 2 in the root table
1106 + // two buttons next to each other
1107 + (4) CONTROL_DEF(&OKButton),
1108 + (5) CONTROL_DEF(&CancelButton),
1109 + END_TABLE
1110 + }
