The scrolledcanvas command creates a scrolled canvas with additional options to manage horizontal and vertical scrollbars. This includes options to control which scrollbars are displayed and the method, i.e. statically or dynamically.
The scrolledcanvas 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 scrolledcanvas widgets:
