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.

423 * Preconditions: Owning row must already have its
424 * y position properly set, or we can't compute

1053 *@@ dlghCreateDlg:
1054 * replacement for WinCreateDlg/WinLoadDlg for creating a
1055 * dialog from a settings array in memory, which is
1056 * formatted automatically.
1057 *
1058 * This does NOT use regular dialog templates from
1059 * module resources. Instead, you pass in an array
1060 * of DLGHITEM structures, which define the controls
1061 * and how they are to be formatted.
1062 *
1063 * The main advantage compared to dialog resources is
1064 * that with this function, you will never have to
1065 * define control _positions_. Instead, you only specify
1066 * the control _sizes_, and all positions are computed
1067 * automatically here. Even better, for many controls,
1068 * auto-sizing is supported according to the control's
1069 * text (e.g. for statics and checkboxes).
1070 *
1071 * A regular standard dialog would use something like
1072 *
1073 + FCF_TITLEBAR | FCF_SYSMENU | FCF_DLGBORDER | FCF_NOBYTEALIGN
1074 *
1075 * for flCreateFlags. To make the dlg sizeable, specify
1076 * FCF_SIZEBORDER instead of FCF_DLGBORDER.
1077 *
1078 * <B>Usage:</B>
1079 *
1080 * Like WinLoadDlg, this creates a standard WC_FRAME and
1081 * subclasses it with fnwpMyDlgProc. It then sends WM_INITDLG
1082 * to the dialog with pCreateParams in mp2.
1083 *
1084 * If this func returns no error, you can then use
1085 * WinProcessDlg with the newly created dialog as usual. In
1086 * your dlg proc, use WinDefDlgProc as usual.
1087 *
1088 * There is NO run-time overhead for either code or memory
1089 * after dialog creation; after this function returns, the
1090 * dialog is a standard dialog as if loaded from WinLoadDlg.
1091 * The array of DLGHITEM structures defines how the
1092 * dialog is set up. All this is ONLY used by this function
1093 * and NOT needed after the dialog has been created.
1094 *
1095 * In DLGHITEM, the "Type" field determines what this
1096 * structure defines. A number of handy macros have been
1097 * defined to make this easier and to provide type-checking
1098 * at compile time. See dialog.h for more.
1099 *
1100 * Essentially, such a dialog item operates similarly to
1101 * HTML tables. There are rows and columns in the table,
1102 * and each control which is specified must be a column
1103 * in some table. Tables may also nest (see below).
1104 *
1105 * The macros are:
1106 *
1107 * -- START_TABLE starts a new table. The tables may nest,
1108 * but must each be properly terminated with END_TABLE.
1109 *
1110 * -- START_GROUP_TABLE(pDef) starts a group. This
1111 * behaves exacly like START_TABLE, but in addition,
1112 * it produces a static group control around the table.
1113 * Useful for group boxes. pDef must point to a
1114 * _CONTROLDEF describing the control to be used for
1115 * the group (usually a WC_STATIC with SS_GROUP style),
1116 * whose size parameter is ignored.
1117 *
1118 * As with START_TABLE, START_GROUP_TABLE must be
1119 * terminated with END_TABLE.
1120 *
1121 * -- START_ROW(fl) starts a new row in a table (regular
1122 * or group). This must also be the first item after
1123 * the (group) table tag.
1124 *
1125 * fl specifies formatting flags for the row. This
1126 * can be one of ROW_VALIGN_BOTTOM, ROW_VALIGN_CENTER,
1127 * ROW_VALIGN_TOP and affects all items in the control.
1128 *
1129 * -- CONTROL_DEF(pDef) defines a control in a table row.
1130 * pDef must point to a CONTROLDEF structure.
1131 *
1132 * Again, there is is NO information in
1133 * CONTROLDEF about a control's _position_.
1134 * Instead, the structure only contains the _size_
1135 * of the control. All positions are computed by
1136 * this function, depending on the sizes of the
1137 * controls and their nesting within the various tables.
1138 *
1139 * If you specify SZL_AUTOSIZE, the size of the
1140 * control is even computed automatically. Presently,
1141 * this only works for statics with SS_TEXT, SS_ICON,
1142 * and SS_BITMAP.
1143 *
1144 * Unless separated with START_ROW items, subsequent
1145 * control items will be considered to be in the same
1146 * row (== positioned next to each other).
1147 *
1148 * There are a few rules, whose violation will produce
1149 * an error:
1150 *
1151 * -- The entire array must be enclosed in a table
1152 * (the "root" table).
1153 *
1154 * -- After START_TABLE or START_GROUP_TABLE, there must
1155 * always be a START_ROW first.
1156 *
1157 * To create a dialog, set up arrays like the following:
1158 *
1159 + // control definitions referenced by DlgTemplate:
1160 + CONTROLDEF
1161 + (1) GroupDef = {
1162 + WC_STATIC, "", ....,

1176 + (4) OKButton = {

1179 + 5 // spacing
1180 + },
1181 + (5) CancelButton = {
1182 + WC_STATIC, "~Cancel", ...,
1183 + { 100, 30 }, // size
1184 + 5 // spacing
1185 + };
1186 +
1187 + DLGHITEM DlgTemplate[] =
1188 + {
1189 + START_TABLE, // root table, required
1190 + START_ROW(0), // row 1 in the root table, required
1191 + // create group on top
1192 + (1) START_GROUP_TABLE(&Group),

1228 * one of the following:

1230 * -- NO_ERROR: only in that case, the phwndDlg ptr
1231 * receives the HWND of the new dialog, which can
1232 * then be given to WinProcessDlg. Don't forget
1233 * WinDestroyWindow.
1234 *
1235 * -- ERROR_NOT_ENOUGH_MEMORY
1236 *
1237 * -- DLGERR_ROW_BEFORE_TABLE: a row definition appeared
1238 * outside a table definition.
1239 *
1240 * -- DLGERR_CONTROL_BEFORE_ROW: a control definition
1241 * appeared right after a table definition. You must
1242 * specify a row first.
1243 *
1244 * -- DLGERR_NULL_CTL_DEF: TYPE_END_TABLE was specified,
1245 * but the CONTROLDEF ptr was NULL.
1246 *
1247 * -- DLGERR_CANNOT_CREATE_FRAME: unable to create the
1248 * WC_FRAME window. Maybe an invalid owner was specified.
1249 *
1250 * -- DLGERR_INVALID_CODE: invalid "Type" field in
1251 * DLGHITEM.
1252 *
1253 * -- DLGERR_TABLE_NOT_CLOSED, DLGERR_TOO_MANY_TABLES_CLOSED:
1254 * improper nesting of TYPE_START_NEW_TABLE and
1255 * TYPE_END_TABLE fields.
