See the "options" manual entry for details on the standard
options. For widgets added to the toolbar, these options
will be propogated if the widget supports the option. For
example, all widgets that support a font option will be
changed if the the toolbar's font option is configured.
- Name:
- balloonBackground
- Class:
- BalloonBackground
- Command-Line Switch:
- -ballooonbackground
Specifies the background color of the balloon help
displayed at the bottom center of a widget on the toolbar
that has a non empty string for its balloonStr
option. The default color is yellow.
- Name:
- balloonDelay1
- Class:
- BalloonDelay1
- Command-Line Switch:
- -balloondelay1
Specifies the length of time (in milliseconds) to wait
before initially posting a balloon help hint window.
This delay is in effect whenever 1) the mouse leaves
the toolbar, or 2) a toolbar item is selected with the
mouse button.
- Name:
- balloonDelay2
- Class:
- BalloonDelay2
- Command-Line Switch:
- -balloondelay2
Specifies the length of time (in milliseconds) to wait
before continuing to post balloon help hint windows.
This delay is in effect after the first time a balloon
hint window is activated. It remains in effect until 1)
the mouse leaves the toolbar, or 2) a toolbar item is
selected with the mouse button.
- Name:
- balloonFont
- Class:
- BalloonFont
- Command-Line Switch:
- -balloonfont
Specifies the font of the balloon help text displayed
at the bottom center of a widget on the toolbar that
has a non empty string for its balloonStr option. The
default font is 6x10.
- Name:
- balloonForeground
- Class:
- BalloonForeground
- Command-Line Switch:
- -ballooonforeground
Specifies the foreground color of the balloon help
displayed at the bottom center of a widget on the toolbar
that has a non empty string for its balloonStr
option. The default color is black.
- Name:
- helpVariable
- Class:
- HelpVariable
- Command-Line Switch:
- -helpvariable
Specifies the global variable to update whenever the
mouse is in motion over a toolbar widget. This global
variable is updated with the current value of the
active widget's helpStr. Other widgets can "watch" this
variable with the trace command, or as is the case with
entry or label widgets, they can set their textVariable
to the same global variable. This allows for a simple
implementation of a help status bar. Whenever the mouse
leaves a menu entry, the helpVariable is set to the
empty string {}.
- Name:
- orient
- Class:
- Orient
- Command-Line Switch:
- -orient
Specifies the orientation of the toolbar. Must be
either horizontal or vertical.
_________________________________________________________________
The toolbar command creates a new window (given by the pathName
argument) and makes it into a toolbar widget. Additional
options, described above may be specified on the command
line or in the option database to configure aspects of
the toolbar such as its colors, font, and orientation. The
toolbar command returns its pathName argument. At the time
this command is invoked, there must not exist a window named
pathName, but pathName's parent must exist.
A toolbar is a widget that displays a collection of widgets
arranged either in a row or a column (depending on the value
of the -orient option). This collection of widgets is usually
for user convenience to give access to a set of commands
or settings. Any widget may be placed on a toolbar.
However, command or value-oriented widgets (such as button,
radiobutton, etc.) are usually the most useful kind of widgets
to appear on a toolbar.
In addition, the toolbar adds two new options to all widgets
that are added to it. These are the helpStr and balloonStr
options. See the discussion for the widget command add
below.
The toolbar 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 args determine the exact behavior of the command.
Many of the widget commands for a toolbar take as one argument
an indicator of which widget item of the toolbar to
operate on. The indicator is called an index and may be
specified in any of the following forms:
number
Specifies the widget numerically, where 0 corresponds
to the first widget in the notebook, 1 to the second,
and so on. (For horizontal, 0 is the leftmost; for
vertical, 0 is the topmost).
end Specifes the last widget in the toolbar's index. If the
toolbar is empty this will return -1.
last Same as end.
pattern
If the index doesn't satisfy any of the above forms,
then this form is used. Pattern is pattern-matched
against the widgetName of each widget in the toolbar,
in order from the first to the last widget, until a
matching entry is found. An exact match must occur.
The following commands are possible for toolbar widgets:
pathName add widgetCommand widgetName ?option value?
Adds a widget with the command widgetCommand whose name
is widgetName to the toolbar. If widgetCommand is
radiobutton or checkbutton, its packing is slightly
padded to match the geometry of button widgets. In
addition, the indicatorOn option is false by default
and the selectColor is that of the toolbar background
by default. This allows Radiobutton and Checkbutton
widgets to be added as icons by simply setting their
bitmap or image options. If additional arguments are
present, they are the set of available options that the
widget type of widgetCommand supports. In addition they
may also be one of the following options:
- -helpstr value
-
Specifes the help string to associate with the
widget. When the mouse moves over the widget, the
variable denoted by helpVariable is set to
helpStr. Another widget can bind to the helpVariable
and thus track status help.
- -balloonstr value
-
Specifes the string to display in a balloon window
for this widget. A balloon window is a small popup
window centered at the bottom of the widget. Usually
the balloonStr value is the name of the item
on the toolbar. It is sometimes known as a hint
window.
When the mouse moves into an item on the toolbar,
a timer is set based on the value of balloonDelay1.
If the mouse stays inside the item for balloonDelay1,
the balloon window will pop up
displaying the balloonStr value. Once the balloon
window is posted, a new timer based on balloonDelay2
is set. This is typically a shorter timer. If
the mouse is moved to another item, the window is
unposted and a new window will be posted over the
item if the shorter delay time is satisfied.
While the balloon window is posted, it can also be
unposted if the item is selected. In this case the
timer is reset to balloonDelay1. Whenever the
mouse leaves the toolbar, the timer is also reset
to balloonDelay1.
This window posting/unposting model is the same
model used in the Windows95 environment.
pathName cget option
Returns the current value of the configuration option
given by option.
pathName configure ?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.
pathName delete index ?index2?
This command deletes all items between index and index2
inclusive. If index2 is omitted then it defaults to
index. Returns an empty string.
pathName index index
Returns the widget's numerical index for the entry
corresponding to index. If index is not found, -1 is
returned.
value?
pathName insert beforeIndex widgetCommand widgetName ?option
Insert a new item named widgetName with the
command widgetCommand before the item specified by
beforeIndex. If widgetCommand is radiobutton or checkbutton,
its packing is slightly padded to match the
geometry of button widgets. In addition, the indicatorOn
option is false by default and the selectColor is
that of the toolbar background by default. This allows
Radiobutton and Checkbutton widgets to be added as
icons by simply setting their bitmap or image options.
The set of available options is the same as specified
in the ad command.
pathName itemcget index option
Returns the current value of the configuration option
given by option for index. The item type of index
determines the valid available options.
pathName itemconfigure index ?option value?
Query or modify the configuration options of the widget
of the toolbar specified by index. If no option is
specified, returns a list describing all of the available
options for index (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 item type of index determines the valid
available options. The set of available options is the
same as specified in the ad command.
