INHERITANCE¶
itk::Widget <- iwidgets::Panedwindow
STANDARD OPTIONS¶
background cursor
See the "options" manual entry for details on the standard options.
Name: height
Class: Height
Command-Line Switch: -height
- Specifies the overall height of the paned window in any of
the forms acceptable to Tk_GetPixels. The default is 10
pixels.
Name: orient
Class: Orient
Command-Line Switch: -orient
- Specifies the orientation of the separators:
vertical or horizontal. The default is horizontal.
Name: sashBorderWidth
Class: BorderWidth
Command-Line Switch: -sashborderwidth
- Specifies a value indicating the width of the 3-D border to
draw around the outside of the sash in any of the forms acceptable to
Tk_GetPixels. The default is 2 pixels.
Name: sashCursor
Class: Cursor
Command-Line Switch: -sashcursor
- Specifies the type of cursor to be displayed in the sash.
The default is crosshair.
Name: sashHeight
Class: Height
Command-Line Switch: -sashheight
- Specifies the height of the sash in any of the forms
acceptable to Tk_GetPixels. The default is 10 pixels.
Name: sashIndent
Class: SashIndent
Command-Line Switch sashindent
- Specifies the placement of the sash along the panes in any
of the forms acceptable to Tk_GetPixels. A positive value causes
the sash to be offset from the near (left/top) side of the pane, and a
negative value causes the sash to be offset from the far (right/bottom)
side. If the offset is greater than the width, then the sash is placed
flush against the side. The default is -10 pixels.
Name: sashWidth
Class: Width
Command-Line Switch: -sashwidth
- Specifies the width of the sash in any of the forms
acceptable to Tk_GetPixels. The default is 10 pixels.
Name: showHandle
Class: ShowHandle
Command-Line Switch: -showhandle
- Specifies whether or not to display the sashes on the
window panes. The default is 1, and valid options are 0 and 1.
Name: thickness
Class: Thickness
Command-Line Switch: -thickness
- Specifies the thickness of the separators in any of the
forms acceptable to Tk_GetPixels. The default is 3 pixels.
Name: width
Class: Width
Command-Line Switch: -width
- Specifies the overall width of the paned window in any of
the forms acceptable to Tk_GetPixels. The default is 10
pixels.
DESCRIPTION¶
The
iwidgets::panedwindow command creates a multiple paned window widget
capable of orienting the panes either vertically or horizontally. Each pane is
itself a frame acting as a child site for other widgets. The border separating
each pane contains a sash which allows user positioning of the panes relative
to one another.
METHODS¶
The
iwidgets::panedwindow command creates a new Tcl command whose name is
pathName. This command may be used to invoke various operations on the
widget. It has the following general form:
pathName option ?arg arg ...?
Option and the
args determine the exact behavior of the command.
Many of the widget commands for the
panedwindow take as one argument an
indicator of which pane of the paned window to operate on. These indicators
are called
indexes and allow reference and manipulation of panes
regardless of their current map state. Paned window indexes may be specified
in any of the following forms:
- number
- Specifies the pane numerically, where 0 corresponds to the
nearest (top/left-most) pane of the paned window.
- end
- Indicates the farthest (bottom/right-most) pane of the
paned window.
- pattern
- If the index doesn't satisfy one of the above forms then
this form is used. Pattern is pattern-matched against the tag of
each pane in the panedwindow, in order from left/top to right/left, until
a matching entry is found. The rules of Tcl_StringMatch are used.
- pathName add tag ?option value
option value?
- Adds a new pane to the paned window on the far side
(right/bottom). The following options may be specified:
- -margin value
- Specifies the border distance between the pane and pane
contents is any of the forms acceptable to Tk_GetPixels. The
default is 8 pixels.
- -minimum value
- Specifies the minimum size that a pane's contents may reach
not inclusive of twice the margin in any of the forms acceptable to
Tk_GetPixels. The default is 10 pixels.
The add method returns the path name of the pane.
- pathName cget option
- Returns the current value of the configuration option given
by option. Option may have any of the values accepted by the
iwidgets::panedwindow command.
- pathName childsite ?index?
- Returns a list of the child site path names or a specific
child site given an index. The list is constructed from the near side
(left/top) to the far side (right/bottom).
- 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 iwidgets::panedwindow command.
- pathName delete index
- Deletes a specified pane given an index.
- pathName fraction percentage
percentage ? percentage percentage ...?
- Sets the visible percentage of the panes. Specifies a set
of percentages which are applied to the visible panes from the near side
(left/top). The number of percentages must be equal to the current number
of visible (mapped) panes and add up to 100.
- pathName hide index
- Changes the visiblity of the specified pane, allowing a
previously displayed pane to be visually removed rather than deleted.
- pathName index index
- Returns the numerical index corresponding to index.
- pathName insert index tag
?option value option value ...?
- Same as the add command except that it inserts the
new pane just before the one given by index, instead of appending
to the end of the panedwindow. The option, and value
arguments have the same interpretation as for the add widget
command.
- pathName paneconfigure index
?options?
- This command is similar to the configure command,
except that it applies to the options for an individual pane, whereas
configure applies to the options for the paned window as a whole.
Options may have any of the values accepted by the add
widget command. If options are specified, options are modified as
indicated in the command and the command returns an empty string. If no
options are specified, returns a list describing the current
options for entry index (see Tk_ConfigureInfo for
information on the format of this list).
- pathName reset
- Redisplays the pane window using default percentages.
- pathName show index
- Changes the visiblity of the specified pane, allowing a
previously hidden pane to be displayed.
NOTES¶
- Dynamic changing of the margin and or minimum options to
values which make the current configuration invalid will block subsequent
sash movement until the fractions are modified via the fraction method.
For example a panedwindow is created with three panes and the minimum and
margin options are at their default settings. Next the user moves the
sashes to compact the panes to one side. Now, if the minimum is increased
on the most compressed pane via the paneconfigure method to a large enough
value, then sash movement is blocked until the fractions are adjusted.
This situation is unusual and under normal operation of the panedwindow,
this problem will never occur.
EXAMPLE¶
package require Iwidgets 4.0
iwidgets::panedwindow .pw -width 300 -height 300
.pw add top
.pw add middle -margin 10
.pw add bottom -margin 10 -minimum 10
pack .pw -fill both -expand yes
foreach pane [.pw childSite] {
button $pane.b -text $pane -relief raised -borderwidth 2
pack $pane.b -fill both -expand yes
}
.pw fraction 50 30 20
.pw paneconfigure 0 -minimum 20
.pw paneconfigure bottom -margin 15
