在输入字段中输入文件名并单击“打开”按钮时,将显示内容。
我希望Entry和Text小部件完全填充Frame3(红色),并在调整应用程序窗口大小时继续这样做。我如何实现这一目标?
这是我的代码:
from Tkinter import *
ALL = N+S+W+E
class Application(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master.rowconfigure(0, weight=1)
self.master.columnconfigure(0, weight=1)
self.grid(sticky=ALL)
def handler(event):
print("clicked at", event.x, event.y)
def show_entry_fields():
#print e1.get()
f=open(e1.get())
out_put=f.read()
l1=Label(f3, text=out_put,fg="purple").grid(row=5,column=2)
return out_put
def call_red():
out_put=show_entry_fields()
Label(f3, text=out_put,fg="red").grid(row=5,column=2)
def call_green():
out_put=show_entry_fields()
Label(f3, text=out_put,fg="green").grid(row=5,column=2)
def call_blue():
out_put=show_entry_fields()
Label(f3, text=out_put,fg="blue").grid(row=5,column=2)
def call_black():
out_put=show_entry_fields()
Label(f3, text=out_put,fg="black").grid(row=5,column=2)
for r in range(4):
self.rowconfigure(r, weight=1)
self.master.rowconfigure(0, weight=1)
self.columnconfigure(0, weight=1)
b1=Button(self, text="Red",command=call_red).grid(row=5, column=0, sticky=ALL)
self.columnconfigure(1, weight=1)
b2=Button(self, text="Blue",command=call_blue).grid(row=5, column=1, sticky=ALL)
self.columnconfigure(2, weight=1)
b3=Button(self, text="Green",command=call_green).grid(row=5, column=2, sticky=ALL)
self.columnconfigure(3, weight=1)
b4=Button(self, text="Black",command=call_black ).grid(row=5, column=3, sticky=ALL)
self.columnconfigure(4, weight=1)
b5=Button(self, text="Open",command=show_entry_fields).grid(row=5, column=4, sticky=ALL)
#------------------------------
f1 = Frame(self, bg="blue")
f1.grid(row=0, column=0, rowspan=2,columnspan=2, sticky=ALL)
f1.bind("<Button-1>", handler)
f1.focus()
f2 = Frame(self, bg="green")
f2.grid(row=2, column=0, rowspan=2,columnspan=2, sticky=ALL)
f2.bind("<Button-1>", handler)
f2.focus()
f3 = Frame(self, bg="red")
f3.grid(row=0, column=2, rowspan=4, columnspan=4, sticky=ALL)
l=Label(f3, text="Enter File Path:").grid(row=1)
e1 = Entry(f3)
e1.grid(row=1,column=2)
root = Tk()
app = Application(master=root)
app.mainloop()
答案 0 :(得分:1)
您应该为放置文字的列和行指定weight
:
f3.grid_columnconfigure(2, weight=1)
f3.grid_rowconfigure(5, weight=1)
这告诉Tkinter它应该将任何额外的空间分配给该行和列,这将使细胞在调整大小时生长。
您可能还想将sticky=ALL
添加到e1
,因此会根据其下方的文字调整大小。
