NAME
labeledwidget - Create and manipulate a labeled widget
SYNOPSIS
labeledwidget pathName ?options?
INHERITANCE
itk::Widget <- labeledwidget
STANDARD OPTIONS
background cursor foreground
See the "options" manual entry for details on the standard options.
DESCRIPTION
The 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.
METHODS
The 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:
WIDGET-SPECIFIC METHODS
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 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 labeledwidget command.
STATIC METHODS
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.
EXAMPLE
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.
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
