'\" 
'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" manual entries.
'\"
'\" .AP type name in/out ?indent?
'\"	Start paragraph describing an argument to a library procedure.
'\"	type is type of argument (int, etc.), in/out is either "in", "out",
'\"	or "in/out" to describe whether procedure reads or modifies arg,
'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS ?type? ?name?
'\"	Give maximum sizes of arguments for setting tab stops.  Type and
'\"	name are examples of largest possible arguments that will be passed
'\"	to .AP later.  If args are omitted, default tab stops are used.
'\"
'\" .BS
'\"	Start box enclosure.  From here until next .BE, everything will be
'\"	enclosed in one large box.
'\"
'\" .BE
'\"	End of box enclosure.
'\"
'\" .CS
'\"	Begin code excerpt.
'\"
'\" .CE
'\"	End code excerpt.
'\"
'\" .VS ?version? ?br?
'\"	Begin vertical sidebar, for use in marking newly-changed parts
'\"	of man pages.  The first argument is ignored and used for recording
'\"	the version when the .VS was added, so that the sidebars can be
'\"	found and removed when they reach a certain age.  If another argument
'\"	is present, then a line break is forced before starting the sidebar.
'\"
'\" .VE
'\"	End of vertical sidebar.
'\"
'\" .DS
'\"	Begin an indented unfilled display.
'\"
'\" .DE
'\"	End of indented unfilled display.
'\"
'\" .SO
'\"	Start of list of standard options for a Tk widget.  The
'\"	options follow on successive lines, in four columns separated
'\"	by tabs.
'\"
'\" .SE
'\"	End of list of standard options for a Tk widget.
'\"
'\" .OP cmdName dbName dbClass
'\"	Start of description of a specific option.  cmdName gives the
'\"	option's name as specified in the class command, dbName gives
'\"	the option's name in the option database, and dbClass gives
'\"	the option's class in the option database.
'\"
'\" .UL arg1 arg2
'\"	Print arg1 underlined, then print arg2 normally.

.SH NAME
tk_dialog \- 建立模式對話框並等待響應
.SH "總覽 SYNOPSIS"
\fBtk_dialog \fIwindow title text bitmap default string string ...\fR
.BE

.SH "描述 DESCRIPTION"
.PP
這個過程是 Tk 腳本庫的一部分。它的參數描述一個對話框:
.TP
\fIwindow\fR
用於對話框的頂層窗口的名字。銷燬叫這個名字的任何現存窗口。
.TP
\fItitle\fR
顯示在窗口管理器給這個對話框的標題欄中的文字。
.TP
\fItext\fR
出現在對話框頂部的消息。
.TP
\fIbitmap\fR
如果非空，則指定在對話框的頂部顯示在文字左邊的一個位圖。如果它是一個空串則在對話框中不顯示位圖。
.TP
\fIdefault\fR
如果它是大於等於零的一個整數，則它給出成爲這個對話框的缺省按鈕的按鈕的索引(0 給最左的按鈕，並以次類推)。如果小於零或是一個空串則沒有缺省按鈕。
.TP
\fIstring\fR
爲這些參數中的每個建立一個按鈕。按從左至右的次序，每個\fIstring\fR 指定要在一個按鈕中顯示的文字。
.PP
在建立了對話框之後，\fBtk_dialog\fR 等待用戶選擇按鈕中的一個，要麼通過用鼠標點擊按鈕之一要麼通用鍵入返回鍵來調用缺省按鈕(如果有的話)。接着它返回選擇的按鈕的索引: 0 是最左的按鈕，1 是下一個按鈕，並以次類推。如果這個對話框的窗口在用戶選擇按鈕中的一個之前就被銷燬了，則返回 -1。
.PP
在等待用戶響應期間，\fBtk_dialog\fR 設置一個本地奪取(grab)。這將防止用戶以除了調用這個對話框之外的任何方式與應用進行交互。
