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.
