3 *@@sourcefile dialog.c:
4 * contains PM helper functions to create and
5 * auto-format dialogs from control arrays in memory.
6 *
7 * As a summary, this code allows you to get rid of
8 * PM dialog resources completely.
9 *
10 * See dlghCreateDlg for an introduction.
11 *
12 * See @dlg_algorithm for the gory details of the new
13 * algorithm used since V1.0.0. Even though much
14 * of this file was rewritten, the new dialog is
15 * backwards-compatible with all the hacks that existing
16 * dialogs might use for aligning things properly.
17 *
18 * In addition, this has dlghMessageBox (a WinMessageBox
19 * replacement) and some helper functions for simulating
20 * dialog behavior in regular window procs (see
21 * dlghSetPrevFocus and others).
22 *
23 * If you are out to find all workarounds to get certain
24 * buggy PM controls aligned right, this file is definitely
25 * the place.
26 *
27 * Usage: All PM programs.

113 *@@gloss: dlg_using_macros Using the Dialog Formatter Macros
114 *
115 * The DLGHITEM macros are:
116 *
117 * -- START_TABLE starts a new table. The tables may nest,
118 * but must each be properly terminated with END_TABLE.
119 *
120 * Note that as opposed to HTML tables, the columns
121 * in the rows of the table are NOT aligned under each
122 * other. If that is what you want, use START_TABLE_ALIGN
123 * instead.
124 *
125 * -- START_GROUP_TABLE(pDef) starts a group. This
126 * behaves exacly like START_TABLE, but in addition,
127 * it produces a static group control around the table.
128 * Useful for group boxes. pDef must point to a
129 * CONTROLDEF describing the control to be used for
130 * the group (usually a WC_STATIC with SS_GROUP style),
131 * whose size parameter is ignored.
132 *
133 * As with START_TABLE, START_GROUP_TABLE must be
134 * terminated with END_TABLE.
135 *
136 * As with START_TABLE, columns in the rows of the table
137 * are NOT aligned under each other. If that is what you
138 * want, use START_GROUP_TABLE_ALIGN instead.
139 *
140 * -- START_ROW(fl) starts a new row in a table (regular
141 * or group). This must also be the first item after
142 * the (group) table tag.
143 *
144 * fl specifies formatting flags for the row. This
145 * can be one of ROW_VALIGN_BOTTOM, ROW_VALIGN_CENTER,
146 * ROW_VALIGN_TOP and affects all items in the row.
147 *
148 * -- CONTROL_DEF(pDef) defines a control in a table row.
149 * pDef must point to a CONTROLDEF structure.
150 *
151 * Again, there is is NO information in CONTROLDEF
152 * about a control's _position_. Instead, the structure
153 * only contains the _size_ of the control. All
154 * positions are computed by this function, depending
155 * on the sizes of the controls and their nesting within
156 * the various tables.
157 *
158 * If you specify SZL_AUTOSIZE with either cx or cy
159 * or both, the size of the control is even computed
160 * automatically. Presently, this only works for statics
161 * with SS_TEXT, SS_ICON, and SS_BITMAP, push buttons,
162 * and radio and check boxes.
163 *
164 * Unless separated with START_ROW items, subsequent
165 * control items will be considered to be in the same
166 * row (== positioned next to each other).
167 *
168 * Columns will only be aligned horizontally if the
169 * container table was specified with START_TABLE_ALIGN
170 * or START_GROUP_TABLE_ALIGN.
171 *
172 * There are a few rules, whose violation will produce
173 * an error:
174 *
175 * -- The entire array must be enclosed in a table
176 * (the "root" table).
177 *
178 * -- After START_TABLE or START_GROUP_TABLE, there must
179 * always be a START_ROW first.
180 *
181 * While it is possible to set up the CONTROLDEFs manually
182 * as static structures, I recommend using the bunch of
183 * other macros that were defined in dialog.h for this.
184 * For example, you can use CONTROLDEF_PUSHBUTTON to create
185 * a push button, and many more.
186 *
187 * To create a dialog, set up arrays like the following:
188 *
189 + // control definitions referenced by DlgTemplate:
190 + CONTROLDEF
191 + (1) GroupDef = CONTROLDEF_GROUP("Group",
192 + -1, // ID
193 + SZL_AUTOSIZE,
194 + SZL_AUTOSIZE),
195 + (2) CnrDef = CONTROLDEF_CONTAINER(-1, // ID,
196 + 50,
197 + 50),
198 + (3) Static = CONTROLDEF_TEXT("Static below cnr",
199 + -1, // ID
200 + SZL_AUTOSIZE,
201 + SZL_AUTOSIZE),
202 + (4) OKButton = CONTROLDEF_DEFPUSHBUTTON("~OK",
203 + DID_OK,
204 + SZL_AUTOSIZE,
205 + SZL_AUTOSIZE),
206 + (5) CancelButton = CONTROLDEF_PUSHBUTTON("~Cancel",
207 + DID_CANCEL,
208 + SZL_AUTOSIZE,
209 + SZL_AUTOSIZE);
210 +
211 + DLGHITEM DlgTemplate[] =
212 + {
213 + START_TABLE, // root table, required
214 + START_ROW(0), // row 1 in the root table, required
215 + // create group on top
216 + (1) START_GROUP_TABLE(&Group),
217 + START_ROW(0),
218 + (2) CONTROL_DEF(&CnrDef),
219 + START_ROW(0),
220 + (3) CONTROL_DEF(&Static),
221 + END_TABLE, // end of group
222 + START_ROW(0), // row 2 in the root table
223 + // two buttons next to each other
224 + (4) CONTROL_DEF(&OKButton),
225 + (5) CONTROL_DEF(&CancelButton),
226 + END_TABLE
227 + }
228 *
229 * This will produce a dlg like this:

275 *
276 * Remark on the box model for subtables:
277 *
278 * We do not want to apply spacing twice for nested tables. This
279 * is especially important for group boxes (i.e. tables which
280 * have a PM group static control created around them). As a
281 * result, the definition is that ONLY COLUMNS HAVE SPACING,
282 * EVER. Neither tables nor rows do.
283 */
284
285/*
286 *@@gloss: dlg_algorithm Dialog formatter algorithm
287 *
288 * See @dlg_boxmodel for information about how the
289 * rectangles are defined.
290 *
291 * The dialog formatter allows you to specify PM dialog layouts
292 * as nested tables, without having to specify a single control
293 * position. In fact, it is impossible to give the dialog
294 * formatter fixed positions. Instead, you give the formatter
295 * the control _sizes_, and everything is layed out automatically.
296 * You may even have the formatter compute the sizes automatically
297 * based on the control classes and values (strings); it is possible
298 * to create dialogs without specifying a single size also.
299 *
300 * There are several tricks to how this works.
301 *
302 * 1) The dialog is supposed to consist of one outer table,
303 * which in turn has rows. The rows in turn have columns.
304 * We process the outer table by iterating over its rows
305 * (see ProcessTable). For each row, we iterate over the
306 * columns (see ProcessRow). Most of the processing then
307 * actually occurs in ProcessColumn.
308 *
309 * 2) Each column can contain a PM control, as specified in a
310 * CONTROLDEF structure on input. Alternatively, a column
311 * can be a nested subtable (with more rows and columns).
312 * If so, ProcessColumn recurses back into ProcessTable
313 * (which again goes into ProcessRow and ProcessColumn).
314 * There is no limit to how deep tables may nest, except
315 * for the stack size of the current thread, of course.
316 *
317 * 3) This whole recursive iteration is performed several times.
318 * In fact, we run through the entire data up to seven times
319 * presently. Only in the last run, we actually create the
320 * controls. Details follow.
321 *
322 * 4) We have sophisticated means for computing the size of
323 * certain controls automatically. See CalcAutoSize.
324 *
325 * The algorithm used here has been greatly reworked with V1.0.0.
326 * Essentially, the new trick is that we first compute all widths
327 * (which requires several iterations since widths may now inherit
328 * from each other), then all heights (which, for many controls,
329 * depend on the widths), then all positions. The previous approach
330 * to calculate widths and heights at the same time has turned out
331 * to not work very well.
332 *
333 * With each of the seven recursive iterations, ProcessTable,
334 * ProcessRow, and ProcessColumn receive a ProcessMode variable,
335 * which is just an integer that is raised with each run. These
336 * are the PROCESS_* constants all over the code.
337 *
338 * In the seven iterations, the following happens:
339 *
340 * 1) PROCESS_1_CALC_MIN_WIDTHS: calculates cxMinContent of all
341 * columns, rows, and tables from the inside to the outside
342 * recursively. cxMinContent specifies the minimum width of
343 * the column, row, and table, respectively. This value is
344 * required for all subsequent computations.
345 *
346 * This works as follows:
347 *
348 * -- From the root table, process all rows. [1]
349 *
350 * -- From each row, process all columns.
351 *
352 * -- For each column, calculate the minimum size of
353 * the content.
354 *
355 * (*) If the column is a control leaf node (i.e.
356 * does not hold a subtable), get the minimum
357 * size of the control.
358 *
359 * (*) If the CONTROLDEF specified an explicit
360 * width, copy it to cxMinContent.
361 *
362 * (*) If the CONTROLDEF specified SZL_AUTOSIZE
363 * for cx, evaluate the control type (icon,
364 * bitmap, text etc.) and set the minimum size
365 * to the result. See CalcAutoSize.
366 *
367 * (*) The control may specify its desired width
368 * as a percentage of the parent table's
369 * width. In that case, set the cxMinContent
370 * to 0 for now because it is to be ignored
371 * in the computation of the parent row and
372 * table widths.
373 *
374 * (*) If the column is a subtable, recurse with
375 * the subtable ([1] above) by calling ProcessTable
376 * again. Then set the control's cxMinContent to
377 * the table's cxMinBox, which was set by the
378 * subtable's ProcessTable (see below).
379 *
380 * After this, we have set the column's cxMinContent
381 * to either a minimum size (explicit or automatic )
382 * or 0.
383 *
384 * -- Set the row's cxMinBox to the sum of the minimum
385 * widths of the contained columns, with padding,
386 * border, and margin applied to each column.
387 *
388 * -- Set the table's cxMinBox to the cxMinBox of the table's
389 * widest row.
390 *
391 * 2) PROCESS_2_CALC_RELATIVE_WIDTHS: calculates the widths of
392 * those columns that have specified that their size should
393 * be a percentage of the parent table's width, and calculate
394 * the content rectangles of all columns and the box rectangles
395 * of the parent rows and tables. Again, do this recursively
396 * from the inside columns to the outside tables.
397 *
398 * First, we inherit table sizes from parent tables in
399 * ProcessTable. If a column has a subtable that has the
400 * TABLE_INHERIT_SIZE table flag set, compute a new cxMinBox
401 * for that table. _After_ that, recurse into the table to allow
402 * subtables of that subtable to inherit that size as well.
403 *
404 * In the columns, this then sets cpContent.cx in the columns,
405 * with the following processing in the control leaf columns:
406 *
407 * (*) If the control has specified an explicit or automatic
408 * width, we have set cxMinContent in PROCESS_1_CALC_MIN_WIDTHS;
409 * copy that width to cpContent.cx.
410 *
411 * (*) However, if the control had specified its desired
412 * width as a percentage of the parent table's width,
413 * calculate the cpContent.cx for the control from the
414 * table's cxMinBox (from PROCESS_1_CALC_MIN_WIDTHS).
415 *
416 * In the rows and tables, cpBox.cx and cpTable.cx is set as
417 * above from the column cpContent.cx values, with spacing applied.
418 *
419 * 3) PROCESS_3_ALIGN_COLUMNS: if the table has the TABLE_ALIGN_COLUMNS
420 * flag set, for each column in the table, find the widest
421 * instance in all rows, and set the cpContent.cx of all
422 * columns in that row to that width.
423 *
424 * 4) PROCESS_4_REMAINDER_WIDTHS: for all controls that have
425 * SZL_REMAINDER set for their widths, fill those so that
426 * they can use up the remaining width in the row.
427 *
428 * 5) PROCESS_5_CALC_HEIGHTS: Now that we know all widths,
429 * calculate the heights. We set cpContent.cy of all columns,
430 * cpRowBox.cy of all rows, and cpTableBox.cy of the tables,
431 * with the following processing in the control leaf columns:
432 *
433 * (*) If the control has specified an explicit or automatic
434 * height, use or compute that. In the case of autosize
435 * height, we now know the final width of the control,
436 * which is important for computing the height of multi-line
437 * static controls (which depend on the width, obviously).
438 * The new approach finally works for the case where a
439 * multi-line static control specifies its width as a
440 * percentage of the parent table, but still wants an
441 * autosize height.
442 *
443 * 6) PROCESS_6_CALC_POSITIONS: Now that we know all heights and
444 * widths, for each column, calculate cpContent.x and y.
445 *
446 * 7) PROCESS_7_CREATE_CONTROLS: finally creates the controls
447 * at the cpContent.x and y position, with the cpContent.cx
448 * and cy size.

2937/*
2938 *@@ dlghCreateDlg:
2939 * replacement for WinCreateDlg/WinLoadDlg for creating a
2940 * dialog from a settings array in memory, which is
2941 * formatted automatically.
2942 *
2943 * This does NOT use regular dialog templates from
2944 * module resources. Instead, you pass in an array
2945 * of DLGHITEM structures, which define the controls
2946 * and how they are to be formatted.
2947 *
2948 * The main advantage compared to dialog resources is
2949 * that with this function, you will never have to
2950 * define control _positions_. Instead, you only specify
2951 * the control _sizes_, and all positions are computed
2952 * automatically here. Even better, for many controls,
2953 * auto-sizing is supported according to the control's
2954 * text (e.g. for statics and checkboxes). This is
2955 * quite similar to HTML tables.
2956 *
2957 * A regular standard dialog would use something like
2958 *
2959 + FCF_TITLEBAR | FCF_SYSMENU | FCF_DLGBORDER | FCF_NOBYTEALIGN | FCF_CLOSEBUTTON
2960 *
2961 * for flCreateFlags. To make the dlg sizeable, specify
2962 * FCF_SIZEBORDER instead of FCF_DLGBORDER.
2963 *
2964 * dialog.h defines FCF_FIXED_DLG and FCF_SIZEABLE_DLG
2965 * to make this more handy.
2966 *
2967 * <B>Usage:</B>
2968 *
2969 * Like WinLoadDlg, this creates a standard WC_FRAME and
2970 * subclasses it with fnwpMyDlgProc. It then sends WM_INITDLG
2971 * to the dialog with pCreateParams in mp2.
2972 *
2973 * If this func returns no error, you can then use
2974 * WinProcessDlg with the newly created dialog as usual. In
2975 * your dlg proc, use WinDefDlgProc as usual.
2976 *
2977 * There is NO run-time overhead for either code or memory
2978 * after dialog creation; after this function returns, the
2979 * dialog is a standard dialog as if loaded from WinLoadDlg.
2980 * The array of DLGHITEM structures defines how the
2981 * dialog is set up. All this is ONLY used by this function
2982 * and NOT needed after the dialog has been created.
2983 *
2984 * In DLGHITEM, the "Type" field determines what this
2985 * structure defines. A number of handy macros have been
2986 * defined to make this easier and to provide type-checking
2987 * at compile time. See dialog.h for the complete (and
2988 * ever-expanding) list of definitions.
2989 *
2990 * See @dlg_using_macros for how to use these macros.
2991 *
2992 * Essentially, such a dialog item operates similarly to
2993 * HTML tables. There are rows and columns in the table,
2994 * and each control which is specified must be a column
2995 * in some table. Tables may also nest (see below).
2996 *
2997 * See @dlg_algorithm for the gory details of the new
2998 * algorithm used since V1.0.0.
2999 *
3000 * See @dlg_boxmodel for information about how the
3001 * rectangles are defined.
3002 *
3003 * <B>Example:</B>
3004 *
3005 * The typical calling sequence would be:
3006 *
3007 + HWND hwndDlg = NULLHANDLE;
3008 + if (NO_ERROR == dlghCreateDlg(&hwndDlg,
3009 + hwndOwner,
3010 + FCF_TITLEBAR | FCF_SYSMENU

3012 + fnwpMyDlgProc,
3013 + "My Dlg Title",
3014 + dlgTemplate, // DLGHITEM array
3015 + ARRAYITEMCOUNT(dlgTemplate),
3016 + NULL, // mp2 for WM_INITDLG

3409 *@@ dlghCreateArray:
3410 * creates a "dialog array" for dynamically
3411 * building a dialog template in memory.
3412 *
3413 * A dialog array is simply an array of
3414 * DLGHITEM structures, as you would normally
3415 * define them statically in the source.
3416 * However, there are situations where you
3417 * might want to leave out certain controls
3418 * depending on certain conditions, which
3419 * can be difficult with static arrays.
3420 *
3421 * As a result, these "array" functions have
3422 * been added to allow for adding static
3423 * DLGHITEM subarrays to a dynamic array in
3424 * memory, which can then be passed to the
3425 * formatter.
3426 *
3427 * Usage:
3428 *
3429 * 1) Call this function with the maximum
3430 * amount of DLGHITEM's that will need
3431 * to be allocated in cMaxItems. Set this
3432 * to the total sum of all DLGHITEM's
3433 * in all the subarrays.
3434 *
3435 * 2) For each of the subarrays, call
3436 * dlghAppendToArray to have the subarray
3437 * appended to the dialog array.
3438 * After each call, DLGARRAY.cDlgItemsNow
3439 * will contain the actual total count of
3440 * DLGHITEM's that were added.
3441 *
3442 * 3) Call dlghCreateDialog with the dialog
3443 * array.
3444 *
3445 * 4) Call dlghFreeArray.
3446 *
3447 * Sort of like this (error checking omitted):
