DESCRIPTION
The panedwindow command creates a new window (given by the pathName argument) and makes it into a
panedwindow widget. Additional options, described above, may be specified on the command line or in
the option database to configure aspects of the panedwindow such as its default background color and
relief. The panedwindow command returns the path name of the new window.
A panedwindow widget contains any number of panes, arranged horizontally or vertically, according to
the value of the -orient option. Each pane contains one widget, and each pair of panes is separated
by a moveable (via mouse movements) sash. Moving a sash causes the widgets on either side of the
sash to be resized.
WIDGET COMMAND
The panedwindow command creates a new Tcl command whose name is the same as the path name of the
panedwindow's window. This command may be used to invoke various operations on the widget. It has
the following general form:
pathName option ?arg arg ...?
PathName is the name of the command, which is the same as the panedwindow widget's path name. Option
and the args determine the exact behavior of the command. The following commands are possible for
panedwindow widgets:
pathName add window ?window ...? ?option value ...?
Add one or more windows to the panedwindow, each in a separate pane. The arguments consist of
the names of one or more windows followed by pairs of arguments that specify how to manage the
windows. Option may have any of the values accepted by the configure subcommand.
pathName cget option
Returns the current value of the configuration option given by option. Option may have any of
the values accepted by the panedwindow command.
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no option is specified, returns a
list describing all of the available options for pathName (see Tk_ConfigureInfo for informa-tion information
tion on the format of this list). If option is specified with no value, then the command
returns a list describing the one named option (this list will be identical to the correspond-ing corresponding
ing sublist of the value returned if no option is specified). If one or more option-value
pairs are specified, then the command modifies the given widget option(s) to have the given
value(s); in this case the command returns an empty string. Option may have any of the values
accepted by the panedwindow command.
pathName forget window ?window ...?
Remove the pane containing window from the panedwindow. All geometry management options for
window will be forgotten.
pathName identify x y
Identify the panedwindow component underneath the point given by x and y, in window coordi-nates. coordinates.
nates. If the point is over a sash or a sash handle, the result is a two element list con-taining containing
taining the index of the sash or handle, and a word indicating whether it is over a sash or a
handle, such as {0 sash} or {2 handle}. If the point is over any other part of the panedwin-dow, panedwindow,
dow, the result is an empty list.
pathName proxy ?args?
This command is used to query and change the position of the sash proxy, used for rubberband-style rubberbandstyle
style pane resizing. It can take any of the following forms:
pathName proxy coord
Return a list containing the x and y coordinates of the most recent proxy location.
pathName proxy forget
Remove the proxy from the display.
pathName proxy place x y
Place the proxy at the given x and y coordinates.
pathName sash ?args?
This command is used to query and change the position of sashes in the panedwindow. It can
take any of the following forms:
pathName sash coord index
Return the current x and y coordinate pair for the sash given by index. Index must be
an integer between 0 and 1 less than the number of panes in the panedwindow. The coor-dinates coordinates
dinates given are those of the top left corner of the region containing the sash.
pathName sash dragto index x y
This command computes the difference between the given coordinates and the coordinates
given to the last sash mark command for the given sash. It then moves that sash the
computed difference. The return value is the empty string.
pathName sash mark index x y
Records x and y for the sash given by index; used in conjunction with later sash dragto
commands to move the sash.
pathName sash place index x y
Place the sash given by index at the given coordinates.
pathName panecget window option
Query a management option for window. Option may be any value allowed by the paneconfigure
subcommand.
pathName paneconfigure window ?option? ?value option value ...?
Query or modify the management options for window. If no option is specified, returns a list
describing all of the available options for pathName (see Tk_ConfigureInfo for information on
the format of this list). If option is specified with no value, then the command returns a
list describing the one named option (this list will be identical to the corresponding sublist
of the value returned if no option is specified). If one or more option-value pairs are spec-ified, specified,
ified, then the command modifies the given widget option(s) to have the given value(s); in
this case the command returns an empty string. The following options are supported:
-after window
Insert the window after the window specified. window should be the name of a window
already managed by pathName.
-before window
Insert the window before the window specified. window should be the name of a window
already managed by pathName.
-height size
Specify a height for the window. The height will be the outer dimension of the window
including its border, if any. If size is an empty string, or if -height is not speci-fied, specified,
fied, then the height requested internally by the window will be used initially; the
height may later be adjusted by the movement of sashes in the panedwindow. Size may be
any value accepted by Tk_GetPixels.
-hide boolean
Controls the visibility of a pane. When the boolean is true (according to Tcl_Get- |
Boolean) the pane will not be visible, but it will still be maintained in the list of |
panes.
-minsize n
Specifies that the size of the window cannot be made less than n. This constraint only
affects the size of the widget in the paned dimension -- the x dimension for horizontal
panedwindows, the y dimension for vertical panedwindows. May be any value accepted by
Tk_GetPixels.
-padx n
Specifies a non-negative value indicating how much extra space to leave on each side of
the window in the X-direction. The value may have any of the forms accepted by Tk_Get-Pixels. Tk_GetPixels.
Pixels.
-pady n
Specifies a non-negative value indicating how much extra space to leave on each side of
the window in the Y-direction. The value may have any of the forms accepted by Tk_Get-Pixels. Tk_GetPixels.
Pixels.
-sticky style
If a window's pane is larger than the requested dimensions of the window, this option
may be used to position (or stretch) the window within its pane. Style is a string
that contains zero or more of the characters n, s, e or w. The string can optionally
contains spaces or commas, but they are ignored. Each letter refers to a side (north,
south, east, or west) that the window will "stick" to. If both n and s (or e and w)
are specified, the window will be stretched to fill the entire height (or width) of its
cavity.
-stretch when
Controls how extra space is allocated to each of the panes. When is one of always, |
first, last, middle, and never. The panedwindow will calculate the required size of |
all its panes. Any remaining (or deficit) space will be distributed to those panes |
marked for stretching. The space will be distributed based on each panes current ratio |
of the whole. The when values have the following definition: |
always ||
This pane will always stretch. |
first ||
Only if this pane is the first pane (left-most or top-most) will it stretch. |
last ||
Only if this pane is the last pane (right-most or bottom-most) will it stretch. |
This is the default value. |
mid- |
dle | |
Only if this pane is not the first or last pane will it stretch. |
never ||
This pane will never stretch. |
-width size
Specify a width for the window. The width will be the outer dimension of the window
including its border, if any. If size is an empty string, or if -width is not speci-fied, specified,
fied, then the width requested internally by the window will be used initially; the
width may later be adjusted by the movement of sashes in the panedwindow. Size may be
any value accepted by Tk_GetPixels.
pathName panes
Returns an ordered list of the widgets managed by pathName.
RESIZING PANES
A pane is resized by grabbing the sash (or sash handle if present) and dragging with the mouse. This
is accomplished via mouse motion bindings on the widget. When a sash is moved, the sizes of the
panes on each side of the sash, and thus the widgets in those panes, are adjusted.
When a pane is resized from outside (e.g. it is packed to expand and fill, and the containing
toplevel is resized), space is added to the final (rightmost or bottommost) pane in the window.
