在 Raspberry Pi 上运行 Python 3.4.2 和 Tkinter 8.6.我想使用网格布局管理器创建一个填充固定大小框架的文本小部件.

Running Python 3.4.2 and Tkinter 8.6 on a Raspberry Pi. I want to create a Text widget that fills a fixed sized frame using the grid layout manager.

如果您运行下面的代码，您将看到文本小部件未填充 800x600 帧.我意识到我可以设置 Text 的宽度和高度属性来填充框架，但这只能使用默认字体，不能完全填充框架.

If you run the code below, you'll see the Text widget doesn't fill the 800x600 frame. I realize I could set the Text's width and height attributes to fill the frame, but this would only work default font and wouldn't fill the frame exactly.

from tkinter import *

class Test(Tk):
  def __init__(self):
    super().__init__()
    self.text = frameText(self)
    self.geometry('{}x{}'.format(800, 600))   

def frameText(frame, **kw):
  ysb = Scrollbar(frame)
  xsb = Scrollbar(frame, orient = HORIZONTAL)
  text = Text(frame, **kw)
  ysb.configure(command = text.yview)
  xsb.configure(command = text.xview)
  text.configure(yscrollcommand = ysb.set, xscrollcommand = xsb.set)
  text.grid(row = 0, column = 0, sticky = N+E+S+W)
  ysb.grid(row = 0, column = 1, sticky = N+S)
  xsb.grid(row = 1, column = 0, sticky = E+W)
  return text

if __name__ == '__main__':
  Test().mainloop()

推荐答案

您需要配置网格，为行和列赋予非零权重，以便它们展开

You need to configure the grid to give the row and column a nonzero weight so that they expand

from tkinter import *

class Test(Tk):
  def __init__(self):
    Tk.__init__(self)
    self.grid_columnconfigure(0, weight=1)
    self.grid_rowconfigure(0, weight=1)
    self.text = frameText(self)
    self.geometry('{}x{}'.format(800, 600))   

def frameText(frame, **kw):
  ysb = Scrollbar(frame)
  xsb = Scrollbar(frame, orient = HORIZONTAL)
  text = Text(frame, **kw)
  ysb.configure(command = text.yview)
  xsb.configure(command = text.xview)
  text.configure(yscrollcommand = ysb.set, xscrollcommand = xsb.set)
  text.grid(row = 0, column = 0, sticky = N+E+S+W)
  ysb.grid(row = 0, column = 1, sticky = "ns")
  xsb.grid(row = 1, column = 0, sticky = E+W)
  return text

if __name__ == '__main__':
  Test().mainloop()
