This is another GUI program using the Tkinter module. It shows you how to change the background and foreground color of a component/widget. In this case it is a button. The button itself is used to toggle the color selection via a color dialog box. Enough comments have been added to help you figure out what is going on.
# change the background/foreground color of a button # askcolor() returns the selected color in two forms # one is rgb = (red,green,blue) for blue = (0,0,255) for red = (255, 0, 0) # the other is a hex number for blue = #0000ff for red = #ff0000 # tested with Python 24 vegaseat 05jul2005 from Tkinter import * from tkColorChooser import askcolor # brings up the color dialog box # the toggle flag flag1 = True def setColor(): # flag1 has to be global, not local (the default) global flag1 (rgb, hexval) = askcolor() if hexval: print rgb, hexval # testing # toggle between bg and fg if flag1: push1.config(bg=hexval, text='Click to set Foreground Color') flag1 = False else: push1.config(fg=hexval, text='Click to set Background Color') flag1 = True #create the form form1 = Tk() # set the form's title form1.title('Change Button Colors') # create a button push1 = Button(form1, text='Click to set Background Color', command=setColor) # configure the button's text push1.config(height=3, font=('times', 20, 'bold')) # pack the button into the frame push1.pack(expand=YES, fill=BOTH) # run the event-loop/program ... form1.mainloop()
