python scripts GUI design

把学习的关于gui设计的代码贴上吧。
这些代码都是在FC6环境下，用kate写的。我感觉kate比较好用。呵呵
今天的代码贴到这里，不语法加亮了，奇怪！可能是没有下载flash插件吧。
不知道你们看着有没有颜色！呵呵

1，click_counter.py

2，labeler.py

from Tkinter import * # create the root window root=Tk() root.title("labeler") root.geometry("200x50") # create a frame in the window to hold other widgets app=Frame(root) # the new frame is placed inside the root window app.grid() # let you arrange widgets # create a label in the frame lb1=Label(app, text="I'm a label!") # app is the place where "i'm a label!" exists lb1.grid() # kick off the window's event loop root.mainloop()

3，lazy_buttons2.py

4，lazy_buttons.py

from Tkinter import * # create a root window root=Tk() root.title("lazy button") root.geometry("200x100") # hint: you must not use "=" here # create a frame in the window to hold other widgets ( the buttons here) app=Frame(root) app.grid() # create a button in the frame bttn1=Button(app, text="I do nothing") bttn1.grid() bttn2=Button(app) bttn2.grid() # all i've done is add a blank button to the frame bttn2.configure(text="Me too") # you can use a widget's configure() method for any widgets option # create a third button in the frame bttn3=Button(app) bttn3.grid() bttn3["text"]="same here" # i access the button's text option through a dictionary-like interface # I set the text option to the string "same here", which puts the text # "same here" on the buttons # kick off the window's event loop root.mainloop()
