The iwidgets::labeledwidget command creates a labeled
widget which contains a label and child site. The child site is a frame
which can filled with any widget via a derived class or though the use of
the childsite method. This class was designed to be a general purpose base
class for supporting the combination of label widget and a childsite. The
options include the ability to position the label around the childsite
widget, modify the font and margin, and control the display of the
labels.
The iwidgets::labeledwidget 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. The following commands are possible for labeledwidget
widgets:
- pathName
childsite
- Return the path name of the child site.
- 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::labeledwidget 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 iwidgets::labeledwidget command.
- iwidgets::Labeledwidget::alignlabels
widget ?widget ...?
- The alignlabels procedure takes a list of widgets derived from the
Labeledwidget class and uses the label margin to make each widget have the
same total space for the combination of label and margin. The net effect
is to left align the labels. Generally, this method is only useful with a
label position of w, which is the default.
Name: label
Class: label
- The label component provides the label for the labeled widget. See the
"label" widget manual entry for details on the label component
item.
Name: lwchildsite
Class: frame
- The lwchildsite component is the user child site for the labeled widget.
See the "frame" widget manual entry for details on the
lwchildsite component item.
- The labeledwidget was primarily meant to be a base class. The
ScrolledListBox and EntryField are good examples of derived classes of the
labeledwidget class. In order to provide equal support for composite
classes, the 'childsite' methods also exists. The following is an example
of 'childsite' method usage.
package require Iwidgets 4.0
iwidgets::labeledwidget .lw -labeltext "Canvas Widget" -labelpos s
pack .lw -fill both -expand yes -padx 10 -pady 10
set cw [canvas [.lw childsite].c -relief raised -width 200 -height 200]
pack $cw -padx 10 -pady 10
