DESCRIPTION
The extbutton extends the behavior of the atomic Tk button by allowing text and an image or bitmap to
coexist. The user may use the -image or -bitmap options to specify an image as well as the -imagepos
option to specify image position relative to the text. Note that the extbutton is not intended to be
used without an image/bitmap. There will be an emtpy space next to the text if no image/bitmap is
specified.
METHODS
The iwidgets::extbutton 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 ...?
INHERITED METHODS
Each of the following methods are inherited from itk::Archetype. See that man page for details.
pathName cget
pathName component
pathName config
pathName configure
WIDGET-SPECIFIC METHODS
pathName invoke
Evaluates the command fragment associated with the -command option.
pathName flash
Simulates the Tk button's flash command.
