Bind the Button1-ButtonRelease event to a function which checks the
length of the SEL tag of the text widget. If it is zero length, disable
the appropriate menu entries, if it is non-zero, enable the appropriate
menu entries.
Simple example:
from Tkinter import *
root = Tk()
textWidget = Text(root)
textWidget.pack()
def onButton1Release(event):
if len(textWidget.tag_ranges(SEL)) == 0:
print 'No text selected. Disable appropriate menu entries'
else:
print 'Some text selected. Enable appropriate menu entries'
textWidget.bind('<Button1-ButtonRelease>', onButton1Release)
root.mainloop()
