69 The Panedwindow method creates a new window (given by the $panedwindow
70 argument) and makes it into a Panedwindow widget. Additional options,
71 described above, may be specified on the command line or in the option
72 database to configure aspects of the Panedwindow such as its default
73 background color and relief.
74 A Panedwindow widget contains any number of panes, arranged
76 horizontally or vertically, according to the value of the -orient
77 option. Each pane contains one widget, and each pair of panes is
78 separated by a moveable (via mouse movements) sash. Moving a sash
79 causes the widgets on either side of the sash to be resized.
80
82 The Panedwindow method may be used to invoke various operations on the
83 widget. It has the following general form:
84 $widget->method(?arg arg ...?);
86 The following commands are possible for Panedwindow widgets:
88 $widget->add(?window ...? ?option value ...?);
90 Add one or more windows to the Panedwindow, each in a separate
91 pane. The arguments consist of the names of one or more windows
92 followed by pairs of arguments that specify how to manage the
93 windows. Option may have any of the values accepted by the
94 configure subcommand.
95 $widget->cget(option);
97 Returns the current value of the configuration option given by
98 option. Option may have any of the values accepted by the
99 Panedwindow command.
100 $widget->configure(?option?, ?value, option, value, ...?);
102 Query or modify the configuration options of the widget. If no
103 option is specified, returns a list describing all of the available
104 options for $widget (see Tk::configure for information on the
105 format of this list). If option is specified with no value, then
106 the command returns a list describing the one named option (this
107 list will be identical to the corresponding sublist of the value
108 returned if no option is specified). If one or more option-value
109 pairs are specified, then the command modifies the given widget
110 option(s) to have the given value(s); in this case the command
111 returns an empty string. Option may have any of the values accepted
112 by the Panedwindow command.
113 $widget->forget(?window ...?);
115 Remove the pane containing $widget from the Panedwindow. All
116 geometry management options for $widget will be forgotten.
117 $widget->identify(x, y);
119 Identify the Panedwindow component underneath the point given by x
120 and y, in window coordinates. If the point is over a sash or a
121 sash handle, the result is a two element list containing the index
122 of the sash or handle, and a word indicating whether it is over a
123 sash or a handle, such as [0, 'sash'] or [2, 'handle']. If the
124 point is over any other part of the Panedwindow, the result is an
125 empty list.
126 $widget->proxy(?args?);
128 This command is used to query and change the position of the sash
129 proxy, used for rubberband-style pane resizing. It can take any of
130 the following forms:
131 $widget->proxyCoord;
133 Return a list containing the x and y coordinates of the most
134 recent proxy location.
135 $widget->proxyForget;
137 Remove the proxy from the display.
138 $widget->proxyPlace(x, y);
140 Place the proxy at the given x and y coordinates.
141 $widget->sash(?args?);
143 This command is used to query and change the position of sashes in
144 the Panedwindow. It can take any of the following forms:
145 $widget->sashCoord(index);
147 Return the current x and y coordinate pair for the sash given
148 by index. Index must be an integer between 0 and 1 less than
149 the number of panes in the Panedwindow. The coordinates given
150 are those of the top left corner of the region containing the
151 sash. $widget->sashDragto(index, x, y) This command computes
152 the difference between the given coordinates and the
153 coordinates given to the last sash coord command for the given
154 sash. It then moves that sash the computed difference. The
155 return value is the empty string.
156 $widget->sashMark(index, x, y);
158 Records x and y for the sash given by index; used in
159 conjunction with later dragto commands to move the sash.
160 $widget->sashPlace(index, x, y);
162 Place the sash given by index at the given coordinates.
163 $widget $widget->panecget(option);
165 Query a management option for $widget. Option may be any value
166 allowed by the paneconfigure subcommand.
167 $widget $widget->paneconfigure(?option? ?value option value ...?);
169 Query or modify the management options for $widget. If no option
170 is specified, returns a list describing all of the available
171 options for $widget (see Tk::configure for information on the
172 format of this list). If option is specified with no value, then
173 the command returns a list describing the one named option (this
174 list will be identical to the corresponding sublist of the value
175 returned if no option is specified). If one or more option-value
176 pairs are specified, then the command modifies the given widget
177 option(s) to have the given value(s); in this case the command
178 returns an empty string. The following options are supported:
179 -after => $widget
181 Insert the window after the window specified. $widget should
182 be the name of a window already managed by $widget.
183 -before => $widget
185 Insert the window before the window specified. $widget should
186 be the name of a window already managed by $widget.
187 -height => size
189 Specify a height for the window. The height will be the outer
190 dimension of the window including its border, if any. If size
191 is an empty string, or if -height is not specified, then the
192 height requested internally by the window will be used
193 initially; the height may later be adjusted by the movement of
194 sashes in the Panedwindow. Size may be any value accepted by
195 Tk_GetPixels.
196 -minsize => n
198 Specifies that the size of the window cannot be made less than
199 n. This constraint only affects the size of the widget in the
200 paned dimension -- the x dimension for horizontal Panedwindows,
201 the y dimension for vertical Panedwindows. May be any value
202 accepted by Tk_GetPixels.
203 -padx => n
205 Specifies a non-negative value indicating how much extra space
206 to leave on each side of the window in the X-direction. The
207 value may have any of the forms accepted by Tk_GetPixels.
208 -pady => n
210 Specifies a non-negative value indicating how much extra space
211 to leave on each side of the window in the Y-direction. The
212 value may have any of the forms accepted by Tk_GetPixels.
213 -sticky => style
215 If a window's pane is larger than the requested dimensions of
216 the window, this option may be used to position (or stretch)
217 the window within its pane. Style is a string that contains
218 zero or more of the characters n, s, e or w. The string can
219 optionally contains spaces or commas, but they are ignored.
220 Each letter refers to a side (north, south, east, or west) that
221 the window will "stick" to. If both n and s (or e and w) are
222 specified, the window will be stretched to fill the entire
223 height (or width) of its cavity.
224 -width => size
226 Specify a width for the window. The width will be the outer
227 dimension of the window including its border, if any. If size
228 is an empty string, or if -width is not specified, then the
229 width requested internally by the window will be used
230 initially; the width may later be adjusted by the movement of
231 sashes in the Panedwindow. Size may be any value accepted by
232 Tk_GetPixels.
233 $widget->panes;
235 Returns an ordered list of the widgets managed by $widget.
236
238 A pane is resized by grabbing the sash (or sash handle if present) and
239 dragging with the mouse. This is accomplished via mouse motion
240 bindings on the widget. When a sash is moved, the sizes of the panes
241 on each side of the sash, and thus the widgets in those panes, are
242 adjusted.
243 When a pane is resized from outside (eg, it is packed to expand and
245 fill, and the containing toplevel is resized), space is added to the
246 final (rightmost or bottommost) pane in the window.
