NAME
panedwindow - Create and manipulate panedwindow widgets SYNOPSIS
panedwindow pathName ?options? STANDARD OPTIONS
-background -borderwidth -cursor -orient -relief See the options manual entry for details on the standard options. WIDGET-SPECIFIC OPTIONS [-handlepad handlePad] When sash handles are drawn, specifies the distance from the top or left end of the sash (depending on the orienta- tion of the widget) at which to draw the handle. May be any value accepted by Tk_GetPixels. [-handlesize handleSize] Specifies the side length of a sash handle. Handles are always drawn as squares. May be any value accepted by Tk_GetPixels. [-height height] Specifies a desired height for the overall panedwindow widget. May be any value accepted by Tk_GetPixels. If an empty string, the widget will be made high enough to allow all contained widgets to have their natural height. [-opaqueresize opaqueResize] Specifies whether panes should be resized as a sash is moved (true), or if resizing should be deferred until the sash is placed (false). [-sashcursor sashCursor] Mouse cur- sor to use when over a sash. If null, sb_h_double_arrow will be used for horizontal panedwindows, and sb_v_double_arrow will be used for vertical panedwindows. [-sashpad sashPad] Specifies the amount of padding to leave of each side of a sash. May be any value accepted by Tk_GetPixels. [-sashrelief sashRelief] Relief to use when drawing a sash. May be any of the standard Tk relief values. [-sashwidth sash- Width] Specifies the width of each sash. May be any value accepted by Tk_GetPixels. [-showhandle showHandle] Specifies whether sash han- dles should be shown. May be any valid Tcl boolean value. [-width width] Specifies a desired width for the overall panedwindow widget. May be any value accepted by Tk_GetPixels. If an empty string, the widget will be made wide enough to allow all contained widgets to have their natural width. _________________________________________________________________ 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 fol- lowed 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 panedwin- dow 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 ini- tially; 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_GetPix- els. 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. SEE ALSO
