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 | |

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. | |

264 | .OP \-command command Command | |
265 | Specifies a Tcl command to associate with the button. This command | |
266 | is typically invoked when mouse button 1 is released over the button | |
267 | window. The button's global variable (\fB\-variable\fR option) will | |
268 | be updated before the command is invoked. | |
269 | .OP \-height height Height | |
270 | Specifies a desired height for the button. | |
271 | If an image or bitmap is being displayed in the button then the value is in | |
272 | screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR); | |
273 | for text it is in lines of text. | |
274 | If this option isn't specified, the button's desired height is computed | |
275 | from the size of the image or bitmap or text being displayed in it. | |
276 | .OP \-indicatoron indicatorOn IndicatorOn | |
277 | Specifies whether or not the indicator should be drawn. Must be a | |
278 | proper boolean value. If false, the \fBrelief\fR option is | |
279 | ignored and the widget's relief is always sunken if the widget is | |
280 | selected and raised otherwise. | |
281 | .OP \-selectcolor selectColor Background | |
282 | Specifies a background color to use when the button is selected. | |
283 | If \fBindicatorOn\fR is true then the color applies to the indicator. | |
284 | Under Windows, this color is used as the background for the indicator | |
285 | regardless of the select state. | |
286 | If \fBindicatorOn\fR is false, this color is used as the background | |
287 | for the entire widget, in place of \fBbackground\fR or \fBactiveBackground\fR, | |
288 | whenever the widget is selected. | |
289 | If specified as an empty string then no special color is used for | |
290 | displaying when the widget is selected. | |
291 | .OP \-offrelief offRelief OffRelief | |
292 | .VS 8.4 | |
293 | Specifies the relief for the checkbutton when the indicator is not drawn and | |
294 | the checkbutton is off. The default value is "raised". By setting this option | |
295 | to "flat" and setting -indicatoron to false and -overrelief to raised, | |
296 | the effect is achieved | |
297 | of having a flat button that raises on mouse-over and which is | |
298 | depressed when activated. This is the behavior typically exhibited by | |
299 | the Align-Left, Align-Right, and Center radiobuttons on the toolbar of a | |
300 | word-processor, for example. | |
301 | .VE 8.4 | |
302 | .OP \-overrelief overRelief OverRelief | |
303 | .VS 8.4 | |
304 | Specifies an alternative relief for the radiobutton, to be used when the | |
305 | mouse cursor is over the widget. This option can be used to make | |
306 | toolbar buttons, by configuring \fB\-relief flat \-overrelief | |
307 | raised\fR. If the value of this option is the empty string, then no | |
308 | alternative relief is used when the mouse cursor is over the radiobutton. | |
309 | The empty string is the default value. | |
310 | .VE 8.4 | |
311 | .OP \-selectimage selectImage SelectImage | |
312 | Specifies an image to display (in place of the \fBimage\fR option) | |
313 | when the radiobutton is selected. | |
314 | This option is ignored unless the \fBimage\fR option has been | |
315 | specified. | |
316 | .OP \-state state State | |
317 | Specifies one of three states for the radiobutton: \fBnormal\fR, \fBactive\fR, | |
318 | or \fBdisabled\fR. In normal state the radiobutton is displayed using the | |
319 | \fBforeground\fR and \fBbackground\fR options. The active state is | |
320 | typically used when the pointer is over the radiobutton. In active state | |
321 | the radiobutton is displayed using the \fBactiveForeground\fR and | |
322 | \fBactiveBackground\fR options. Disabled state means that the radiobutton | |
323 | should be insensitive: the default bindings will refuse to activate | |
324 | the widget and will ignore mouse button presses. | |
325 | In this state the \fBdisabledForeground\fR and | |
326 | \fBbackground\fR options determine how the radiobutton is displayed. | |
327 | .OP \-value value Value | |
328 | Specifies value to store in the button's associated variable whenever | |
329 | this button is selected. | |
330 | .OP \-variable variable Variable | |
331 | Specifies name of global variable to set whenever this button is | |
332 | selected. Changes in this variable also cause the button to select | |
333 | or deselect itself. | |
334 | Defaults to the value \fBselectedButton\fR. | |
335 | .OP \-width width Width | |
336 | Specifies a desired width for the button. | |
337 | If an image or bitmap is being displayed in the button, the value is in | |
338 | screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR); | |
339 | for text it is in characters. | |
340 | If this option isn't specified, the button's desired width is computed | |
341 | from the size of the image or bitmap or text being displayed in it. | |
342 | .BE | |

344 | .SH DESCRIPTION | |
345 | .PP | |
346 | The \fBradiobutton\fR command creates a new window (given by the | |
347 | \fIpathName\fR argument) and makes it into a radiobutton widget. | |
348 | Additional | |
349 | options, described above, may be specified on the command line | |
350 | or in the option database | |
351 | to configure aspects of the radiobutton such as its colors, font, | |
352 | text, and initial relief. The \fBradiobutton\fR command returns its | |
353 | \fIpathName\fR argument. At the time this command is invoked, | |
354 | there must not exist a window named \fIpathName\fR, but | |
355 | \fIpathName\fR's parent must exist. | |
356 | .PP | |
357 | .VS | |
358 | A radiobutton is a widget that displays a textual string, bitmap or image | |
359 | and a diamond or circle called an \fIindicator\fR. | |
360 | .VE | |
361 | If text is displayed, it must all be in a single font, but it | |
362 | can occupy multiple lines on the screen (if it contains newlines | |
363 | or if wrapping occurs because of the \fBwrapLength\fR option) and | |
364 | one of the characters may optionally be underlined using the | |
365 | \fBunderline\fR option. A radiobutton has | |
366 | all of the behavior of a simple button: it can display itself in either | |
367 | of three different ways, according to the \fBstate\fR option; | |
368 | it can be made to appear | |
369 | raised, sunken, or flat; it can be made to flash; and it invokes | |
370 | a Tcl command whenever mouse button 1 is clicked over the | |
371 | check button. | |
372 | .PP | |
373 | In addition, radiobuttons can be \fIselected\fR. | |
374 | If a radiobutton is selected, the indicator is normally | |
375 | .VS | |
376 | drawn with a selected appearance, and | |
377 | a Tcl variable associated with the radiobutton is set to a particular | |
378 | value (normally 1). | |
379 | Under Unix, the indicator is drawn with a sunken relief and a special | |
380 | color. Under Windows, the indicator is drawn with a round mark inside. | |
381 | If the radiobutton is not selected, then the indicator is drawn with a | |
382 | deselected appearance, and the associated variable is | |
383 | set to a different value (typically 0). | |
384 | Under Unix, the indicator is drawn with a raised relief and no special | |
385 | color. Under Windows, the indicator is drawn without a round mark inside. | |
386 | .VE | |
387 | Typically, several radiobuttons share a single variable and the | |
388 | value of the variable indicates which radiobutton is to be selected. | |
389 | When a radiobutton is selected it sets the value of the variable to | |
390 | indicate that fact; each radiobutton also monitors the value of | |
391 | the variable and automatically selects and deselects itself when the | |
392 | variable's value changes. | |
393 | By default the variable \fBselectedButton\fR | |
394 | is used; its contents give the name of the button that is | |
395 | selected, or the empty string if no button associated with that | |
396 | variable is selected. | |
397 | The name of the variable for a radiobutton, | |
398 | plus the variable to be stored into it, may be modified with options | |
399 | on the command line or in the option database. | |
400 | Configuration options may also be used to modify the way the | |
401 | indicator is displayed (or whether it is displayed at all). | |
402 | By default a radiobutton is configured to select itself on button clicks. | |
403 | .SH "WIDGET COMMAND" | |
404 | .PP | |
405 | The \fBradiobutton\fR command creates a new Tcl command whose | |
406 | name is \fIpathName\fR. This | |
407 | command may be used to invoke various | |
408 | operations on the widget. It has the following general form: | |
409 | .CS | |
410 | \fIpathName option \fR?\fIarg arg ...\fR? | |
411 | .CE | |
412 | \fIOption\fR and the \fIarg\fRs | |
413 | determine the exact behavior of the command. The following | |
414 | commands are possible for radiobutton widgets: | |
415 | .TP | |
416 | \fIpathName \fBcget\fR \fIoption\fR | |
417 | Returns the current value of the configuration option given | |
418 | by \fIoption\fR. | |
419 | \fIOption\fR may have any of the values accepted by the \fBradiobutton\fR | |
420 | command. | |
421 | .TP | |
422 | \fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? | |
423 | Query or modify the configuration options of the widget. | |
424 | If no \fIoption\fR is specified, returns a list describing all of | |
425 | the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for | |
426 | information on the format of this list). If \fIoption\fR is specified | |
427 | with no \fIvalue\fR, the command returns a list describing the | |
428 | one named option (this list will be identical to the corresponding | |
429 | sublist of the value returned if no \fIoption\fR is specified). If | |
430 | one or more \fIoption\-value\fR pairs are specified, the command | |
431 | modifies the given widget option(s) to have the given value(s); in | |
432 | this case the command returns an empty string. | |
433 | \fIOption\fR may have any of the values accepted by the \fBradiobutton\fR | |
434 | command. | |
435 | .TP | |
436 | \fIpathName \fBdeselect\fR | |
437 | Deselects the radiobutton and sets the associated variable to an | |
438 | empty string. | |
439 | If this radiobutton was not currently selected, the command has | |
440 | no effect. | |
441 | .TP | |
442 | \fIpathName \fBflash\fR | |
443 | Flashes the radiobutton. This is accomplished by redisplaying the radiobutton | |
444 | several times, alternating between active and normal colors. At | |
445 | the end of the flash the radiobutton is left in the same normal/active | |
446 | state as when the command was invoked. | |
447 | This command is ignored if the radiobutton's state is \fBdisabled\fR. | |

450 | Does just what would have happened if the user invoked the radiobutton | |
451 | with the mouse: selects the button and invokes | |
452 | its associated Tcl command, if there is one. | |
453 | The return value is the return value from the Tcl command, or an | |
454 | empty string if there is no command associated with the radiobutton. | |
455 | This command is ignored if the radiobutton's state is \fBdisabled\fR. | |

457 | \fIpathName \fBselect\fR | |
458 | Selects the radiobutton and sets the associated variable to the | |
459 | value corresponding to this widget. | |
460 | .SH BINDINGS | |
461 | .PP | |
462 | Tk automatically creates class bindings for radiobuttons that give them | |
463 | the following default behavior: | |
464 | .IP [1] | |
465 | .VS | |
466 | On Unix systems, a radiobutton activates whenever the mouse passes | |
467 | over it and deactivates whenever the mouse leaves the radiobutton. On | |
468 | Mac and Windows systems, when mouse button 1 is pressed over a | |
469 | radiobutton, the button activates whenever the mouse pointer is inside | |
470 | the button, and deactivates whenever the mouse pointer leaves the | |
471 | button. | |
472 | .VE | |
473 | .IP [2] | |
474 | When mouse button 1 is pressed over a radiobutton it is invoked (it | |
475 | becomes selected and the command associated with the button is | |
476 | invoked, if there is one). | |
477 | .IP [3] | |
478 | When a radiobutton has the input focus, the space key causes the radiobutton | |
479 | to be invoked. | |
480 | .PP | |
481 | If the radiobutton's state is \fBdisabled\fR then none of the above | |
482 | actions occur: the radiobutton is completely non-responsive. | |
483 | .PP | |
484 | The behavior of radiobuttons can be changed by defining new bindings for | |
485 | individual widgets or by redefining the class bindings. | |
