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 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
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
coordinates. If the point is over a sash or a sash handle, the result is a two
element list containing 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 panedwindow, 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 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 coordinates 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
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. 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 specified, 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_GetBoolean) 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_GetPixels.
-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_GetPixels.
-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. │
middle │
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 specified, 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.
