tixBalloon - Create and manipulate tixBalloon widgets
class is derived from the TixShell
inherits all the commands, options and subwidgets of its super-class.
The Balloon widget supports all the standard options of a frame widget. See the
manual entry for details on the standard options.
Specifies how long the balloon should wait before popping up in a widget.
Specifies the which help
message to display when the mouse pointer enters a widget associated with this
balloon. Valid options are both
: display both the balloon message and
the status bar message, balloon
: display only the balloon message,
: display only the status bar message and none
: display no
messages. [-statusbar statusBar]
Specifies the widget to use as the status bar of this balloon. This widget
must have a "-text" option. Usually a label widget is used.
- The label widget that shows the little arrow bitmap in the pop-up balloon
- The message widget that shows the descriptive message in the the pop-up
command creates a new window (given by the pathName
argument) and makes it into a Balloon widget. Additional options, described
above, may be specified on the command line or in the option database to
configure aspects of the Balloon widget such as its cursor and relief.
The Balloon widget can be used to show popped-up messages that describe the
functions of the widgets in an application. A Balloon widget can be bound to a
number of widgets. When the user moves the cursor inside a widget to which a
Balloon widget has been bound, a small pop-up window with a descriptive
message will be shown on the screen.
command creates a new Tcl command whose name is the same
as the path name of the Balloon widget's window. This command may be used to
invoke various operations on the widget. It has the following general form:
pathName option ?arg arg ...?
is the name of the command, which is the same as the Balloon
widget's path name. Option
and the arg
s determine the exact
behavior of the command. The following commands are possible for Balloon
- pathName bind widget ?option value ... ?
- Binds the Balloon widget to the widget. The messages to be shown
can be passed as extra arguments to this command in option
value pairs. Possible options: -balloonmsg specifies the
string to show on the pop-up balloon window; -statusmsg specifies
the string to show on the status bar; -msg specifies a string to
show on both the balloon window and the stats bar window. When used
together, the -msg option has a lower precedence than the
-balloonmsg and -statusmsg options.
The bind command can also be used to change the messages after the
initial bindings were set. Example:
# Add balloon binding
.bal bind .b -msg "This is a button"
# Change the balloon binding
.bal bind .b -msg "This is a useful button"
- pathName cget option
- Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the
- 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 tixBalloon command.
- pathName unbind widget
- Cancels the Balloon widget's binding with widget.
- pathName subwidget name ?args?
- When no options are given, this command returns the pathname of the
subwidget of the specified name.
When options are given, the widget command of the specified subwidget will
be called with these options.
After a widget has be bound to a Balloon widget, when the user moves the cursor
into this widget, the Balloon widget is activated: if the -balloonmsg
option of this widget is set, the balloon window pops up; if the
option of this widget is set, the message will be displayed
in the status bar widget.
When the user moves the cursor out of the widget, the Balloon widget is
de-activated: the balloon window is withdrawn and the status-bar message
