10 | '\" The definitions below are for supplemental macros used in Tcl/Tk | |
11 | '\" manual entries. | |
12 | '\" | |
13 | '\" .AP type name in/out ?indent? | |
14 | '\" Start paragraph describing an argument to a library procedure. | |
15 | '\" type is type of argument (int, etc.), in/out is either "in", "out", | |
16 | '\" or "in/out" to describe whether procedure reads or modifies arg, | |
17 | '\" and indent is equivalent to second arg of .IP (shouldn't ever be | |
18 | '\" needed; use .AS below instead) | |
19 | '\" | |
20 | '\" .AS ?type? ?name? | |
21 | '\" Give maximum sizes of arguments for setting tab stops. Type and | |
22 | '\" name are examples of largest possible arguments that will be passed | |
23 | '\" to .AP later. If args are omitted, default tab stops are used. | |
24 | '\" | |
25 | '\" .BS | |
26 | '\" Start box enclosure. From here until next .BE, everything will be | |
27 | '\" enclosed in one large box. | |
28 | '\" | |
29 | '\" .BE | |
30 | '\" End of box enclosure. | |

35 | '\" .CE | |
36 | '\" End code excerpt. | |
37 | '\" | |
38 | '\" .VS ?version? ?br? | |
39 | '\" Begin vertical sidebar, for use in marking newly-changed parts | |
40 | '\" of man pages. The first argument is ignored and used for recording | |
41 | '\" the version when the .VS was added, so that the sidebars can be | |
42 | '\" found and removed when they reach a certain age. If another argument | |
43 | '\" is present, then a line break is forced before starting the sidebar. | |
44 | '\" | |
45 | '\" .VE | |
46 | '\" End of vertical sidebar. | |
47 | '\" | |
48 | '\" .DS | |
49 | '\" Begin an indented unfilled display. | |
50 | '\" | |
51 | '\" .DE | |
52 | '\" End of indented unfilled display. | |
53 | '\" | |
54 | '\" .SO | |
55 | '\" Start of list of standard options for a Tk widget. The | |
56 | '\" options follow on successive lines, in four columns separated | |
57 | '\" by tabs. | |
58 | '\" | |
59 | '\" .SE | |
60 | '\" End of list of standard options for a Tk widget. | |
61 | '\" | |
62 | '\" .OP cmdName dbName dbClass | |
63 | '\" Start of description of a specific option. cmdName gives the | |
64 | '\" option's name as specified in the class command, dbName gives | |
65 | '\" the option's name in the option database, and dbClass gives | |
66 | '\" the option's class in the option database. | |

264 | .OP \-direction direction Height | |
265 | Specifies where the menu is going to be popup up. \fBabove\fR tries to | |
266 | pop the menu above the menubutton. \fBbelow\fR tries to pop the menu | |
267 | below the menubutton. \fBleft\fR tries to pop the menu to the left of | |
268 | the menubutton. \fBright\fR tries to pop the menu to the right of the | |
269 | menu button. \fBflush\fR pops the menu directly over the menubutton. | |
270 | In the case of \fBabove\fR or \fBbelow\fR, the direction will be | |
271 | reversed if the menu would show offscreen. | |
272 | .OP \-height height Height | |
273 | Specifies a desired height for the menubutton. | |
274 | If an image or bitmap is being displayed in the menubutton then the value is in | |
275 | screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR); | |
276 | for text it is in lines of text. | |
277 | If this option isn't specified, the menubutton's desired height is computed | |
278 | from the size of the image or bitmap or text being displayed in it. | |
279 | .OP \-indicatoron indicatorOn IndicatorOn | |
280 | The value must be a proper boolean value. If it is true then | |
281 | a small indicator rectangle will be displayed on the right side | |
282 | of the menubutton and the default menu bindings will treat this | |
283 | as an option menubutton. If false then no indicator will be | |
284 | displayed. | |
285 | .OP \-menu menu MenuName | |
286 | Specifies the path name of the menu associated with this menubutton. | |
287 | The menu must be a child of the menubutton. | |
288 | .OP \-state state State | |
289 | Specifies one of three states for the menubutton: \fBnormal\fR, \fBactive\fR, | |
290 | or \fBdisabled\fR. In normal state the menubutton is displayed using the | |
291 | \fBforeground\fR and \fBbackground\fR options. The active state is | |
292 | typically used when the pointer is over the menubutton. In active state | |
293 | the menubutton is displayed using the \fBactiveForeground\fR and | |
294 | \fBactiveBackground\fR options. Disabled state means that the menubutton | |
295 | should be insensitive: the default bindings will refuse to activate | |
296 | the widget and will ignore mouse button presses. | |
297 | In this state the \fBdisabledForeground\fR and | |
298 | \fBbackground\fR options determine how the button is displayed. | |
299 | .OP \-width width Width | |
300 | Specifies a desired width for the menubutton. | |
301 | If an image or bitmap is being displayed in the menubutton then the value is in | |
302 | screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR); | |
303 | for text it is in characters. | |
304 | If this option isn't specified, the menubutton's desired width is computed | |
305 | from the size of the image or bitmap or text being displayed in it. | |

308 | .SH INTRODUCTION | |
309 | .PP | |
310 | The \fBmenubutton\fR command creates a new window (given by the | |
311 | \fIpathName\fR argument) and makes it into a menubutton widget. | |
312 | Additional | |
313 | options, described above, may be specified on the command line | |
314 | or in the option database | |
315 | to configure aspects of the menubutton such as its colors, font, | |
316 | text, and initial relief. The \fBmenubutton\fR command returns its | |
317 | \fIpathName\fR argument. At the time this command is invoked, | |
318 | there must not exist a window named \fIpathName\fR, but | |
319 | \fIpathName\fR's parent must exist. | |
320 | .PP | |
321 | A menubutton is a widget that displays a textual string, bitmap, or image | |
322 | and is associated with a menu widget. | |
323 | If text is displayed, it must all be in a single font, but it | |
324 | can occupy multiple lines on the screen (if it contains newlines | |
325 | or if wrapping occurs because of the \fBwrapLength\fR option) and | |
326 | one of the characters may optionally be underlined using the | |
327 | \fBunderline\fR option. In normal usage, pressing | |
328 | mouse button 1 over the menubutton causes the associated menu to | |
329 | be posted just underneath the menubutton. If the mouse is moved over | |
330 | the menu before releasing the mouse button, the button release | |
331 | causes the underlying menu entry to be invoked. When the button | |
332 | is released, the menu is unposted. | |
333 | .PP | |
334 | Menubuttons are typically organized into groups called menu bars | |
335 | that allow scanning: | |
336 | if the mouse button is pressed over one menubutton (causing it | |
337 | to post its menu) and the mouse is moved over another menubutton | |
338 | in the same menu bar without releasing the mouse button, then the | |
339 | menu of the first menubutton is unposted and the menu of the | |
340 | new menubutton is posted instead. | |
341 | .PP | |
342 | There are several interactions between menubuttons and menus; see | |
343 | the \fBmenu\fR manual entry for information on various menu configurations, | |
344 | such as pulldown menus and option menus. | |
345 | ||
346 | .SH "WIDGET COMMAND" | |
347 | .PP | |
348 | The \fBmenubutton\fR command creates a new Tcl command whose | |
349 | name is \fIpathName\fR. This | |
350 | command may be used to invoke various | |
351 | operations on the widget. It has the following general form: | |
352 | .CS | |
353 | \fIpathName option \fR?\fIarg arg ...\fR? | |
354 | .CE | |
355 | \fIOption\fR and the \fIarg\fRs | |
356 | determine the exact behavior of the command. The following | |
357 | commands are possible for menubutton widgets: | |
358 | .TP | |
359 | \fIpathName \fBcget\fR \fIoption\fR | |
360 | Returns the current value of the configuration option given | |
361 | by \fIoption\fR. | |
362 | \fIOption\fR may have any of the values accepted by the \fBmenubutton\fR | |
363 | command. | |
364 | .TP | |
365 | \fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? | |
366 | Query or modify the configuration options of the widget. | |
367 | If no \fIoption\fR is specified, returns a list describing all of | |
368 | the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for | |
369 | information on the format of this list). If \fIoption\fR is specified | |
370 | with no \fIvalue\fR, then the command returns a list describing the | |
371 | one named option (this list will be identical to the corresponding | |
372 | sublist of the value returned if no \fIoption\fR is specified). If | |
373 | one or more \fIoption\-value\fR pairs are specified, then the command | |
374 | modifies the given widget option(s) to have the given value(s); in | |
375 | this case the command returns an empty string. | |
376 | \fIOption\fR may have any of the values accepted by the \fBmenubutton\fR | |
377 | command. | |
378 | ||
379 | .SH "DEFAULT BINDINGS" | |
380 | .PP | |
381 | Tk automatically creates class bindings for menubuttons that give them | |
382 | the following default behavior: | |
383 | .IP [1] | |
384 | A menubutton activates whenever the mouse passes over it and deactivates | |
385 | whenever the mouse leaves it. | |
386 | .IP [2] | |
387 | Pressing mouse button 1 over a menubutton posts the menubutton: | |
388 | its relief changes to raised and its associated menu is posted | |
389 | under the menubutton. If the mouse is dragged down into the menu | |
390 | with the button still down, and if the mouse button is then | |
391 | released over an entry in the menu, the menubutton is unposted | |
392 | and the menu entry is invoked. | |
393 | .IP [3] | |
394 | If button 1 is pressed over a menubutton and then released over that | |
395 | menubutton, the menubutton stays posted: you can still move the mouse | |
396 | over the menu and click button 1 on an entry to invoke it. | |
397 | Once a menu entry has been invoked, the menubutton unposts itself. | |
398 | .IP [4] | |
399 | If button 1 is pressed over a menubutton and then dragged over some | |
400 | other menubutton, the original menubutton unposts itself and the | |
401 | new menubutton posts. | |
402 | .IP [5] | |
403 | If button 1 is pressed over a menubutton and released outside | |
404 | any menubutton or menu, the menubutton unposts without invoking | |
405 | any menu entry. | |
406 | .IP [6] | |
407 | When a menubutton is posted, its associated menu claims the input | |
408 | focus to allow keyboard traversal of the menu and its submenus. | |
409 | See the \fBmenu\fR manual entry for details on these bindings. | |
410 | .IP [7] | |
411 | If the \fBunderline\fR option has been specified for a menubutton | |
412 | then keyboard traversal may be used to post the menubutton: | |
413 | Alt+\fIx\fR, where \fIx\fR is the underlined character (or its | |
414 | lower-case or upper-case equivalent), may be typed in any window | |
415 | under the menubutton's toplevel to post the menubutton. | |
416 | .IP [8] | |
417 | The F10 key may be typed in any window to post the first menubutton | |
418 | under its toplevel window that isn't disabled. | |
419 | .IP [9] | |
420 | If a menubutton has the input focus, the space and return keys | |
421 | post the menubutton. | |
422 | .PP | |
423 | If the menubutton's state is \fBdisabled\fR then none of the above | |
424 | actions occur: the menubutton is completely non-responsive. | |
425 | .PP | |
426 | The behavior of menubuttons can be changed by defining new bindings for | |
427 | individual widgets or by redefining the class bindings. | |
