Tk::ExecuteCommand Description

Tk::ExecuteCommand Perl module can execute a command asynchronously (non-blocking). Tk::ExecuteCommand Perl module can execute a command asynchronously (non-blocking).SYNOPSIS $exec = $parent->ExecuteCommand;Tk::ExecuteCommand runs a command yet still allows Tk events to flow. All command output and errors are displayed in a window.This ExecuteCommand mega widget is composed of an LabEntry widget for command entry, a "Do It" Button that initiates command execution, and a ROText widget that collects command execution output.While the command is executing, the "Do It" Button changes to a "Cancel" Button that can prematurely kill the executing command. The kill_command method does the same thing programmatically.The primary benefit of this widget is the ability to execute system commands asynchronously without blocking Tk's event loop. The widget doesn't even have to be managed (pack/grid), see the EXAMPLES section.OPTIONS-commandThe command to execute asynchronously.-entryWidthCharacter width of command Entry widget.-heightCharacter height of the ROText widget.-labelLabel text for command Entry widget.-textLabel text for "Do It!"
