我正在使用Python构建一个小应用程序,并尝试使用Tkinter进行一些GUI编程。这是到目前为止我创建的GUI:
应用程序疑问:
如何确保屏幕截图中的三个LableFrames(A,B和C)具有相同的宽度?(或者说,宽度与三者中最宽的相等?例如,在屏幕截图中,A是最宽的,我希望B和C也能一样宽-直到线D)。
(它不必动态计算 - 只要我第一次编写代码时可以确保宽度相同即可。它们不需要在运行时更改。)
Tk Grid Geometry Manager疑问:
当您使用框架时,网格(行、列)是否仅适用于框架的大小,还是根据表单的大小(根窗口)计算的?
如何确定网格中列的大小?
- 我还没有完全理解网格中'weight'的作用。何时应该使用?
Python GUI代码:
import Tkinter
if __name__ == '__main__':
form = Tkinter.Tk()
getFld = Tkinter.IntVar()
form.wm_title('File Parser')
stepOne = Tkinter.LabelFrame(form, text=" 1. Enter File Details: ")
stepOne.grid(row=0, columnspan=7, sticky='W', \
padx=5, pady=5, ipadx=5, ipady=5)
helpLf = Tkinter.LabelFrame(form, text=" Quick Help ")
helpLf.grid(row=0, column=9, columnspan=2, rowspan=8, \
sticky='NS', padx=5, pady=5)
helpLbl = Tkinter.Label(helpLf, text="Help will come - ask for it.")
helpLbl.grid(row=0)
stepTwo = Tkinter.LabelFrame(form, text=" 2. Enter Table Details: ")
stepTwo.grid(row=2, columnspan=7, sticky='W', \
padx=5, pady=5, ipadx=5, ipady=5)

fldLbl = Tkinter.Label(stepTwo, \
text="Enter the field (column) names of the table:")
fldLbl.grid(row=4, column=0, padx=5, pady=2, sticky='W')
getFldChk = Tkinter.Checkbutton(stepTwo, \
text="Get fields automatically from input file",\
onvalue=1, offvalue=0)
getFldChk.grid(row=4, column=1, columnspan=3, pady=2, sticky='WE')
fldRowTxt = Tkinter.Entry(stepTwo)
fldRowTxt.grid(row=5, columnspan=5, padx=5, pady=2, sticky='WE')
transChk = Tkinter.Checkbutton(stepThree, \
text="Enable Transaction", onvalue=1, offvalue=0)
transChk.grid(row=6, sticky='W', padx=5, pady=2)
transRwLbl = Tkinter.Label(stepThree, \
text=" => Specify number of rows per transaction:")
transRwLbl.grid(row=6, column=2, columnspan=2, \
sticky='W', padx=5, pady=2)
transRwTxt = Tkinter.Entry(stepThree)
transRwTxt.grid(row=6, column=4, sticky='WE')
form.mainloop()
