Command options by class
The following is a list of generic widget options that you can assign
to any widgets created by SCO Visual Tcl.
All widgets have
``Geometry class options''
(used for specifying their positioning)
``Object class options''
specifying their basic attributes).
Some widgets also have:
Some common terminology is used:
The name of a Tcl command or procedure associated with a widget. (For
example, if the -callback cmd option is set for a
given widget, it specifies that the cmd procedure is
to be executed as a callback by that widget.)
The widget hierarchy of an object used when creating the object.
(For example, to create name as a child of parent,
use the object_name parent.name).
The name returned when creating an object.
This name is used when performing
commands such as get, set, select, and delete
on widgets. It is also used when specifying
a widget hierarchy for a new object.
The form of a widget name is defined as a path through the widget
tree. As commands are sent to the server, widgets are created; then,
further child widgets are added. For example, a form may have a dialog
as its child, and the dialog may have a text box and some buttons as
children. The dialog will therefore have a name of the form:
formname.dialogname; and the buttons will be named
All widget options are followed by the access attributes. These
are as follows:
indicates that the option can be set at widget creation time
indicates that the options can be retrieved by
indicates that the option can be set at any time after the widget
has been created, using
For example, an option that only has the ``C'' attribute must be set
at widget creation time or not at all. An option with all attributes
set may be applied to a widget at creation time, or at any subsequent
time (using VtSet),
and it is possible to retrieve the option using VtGet.
