我的目标是让我新生的自定义GUI应用程序（其子类为tkinter.Frame）在调整其父窗口的大小时在两个方向上独立扩展。当我第一次仅使用本机tkinter类在脚本中构建它时，此方法就起作用了（有关该代码，请参见文章底部），但是自从我将其重构为子类（请参见下面的第一段代码）以来，它坚持调整大小时保持其原始比例。就是说，如果我最大化父窗口，则主GUI框架仅沿对角线方向扩展，直到其到达屏幕底部为止。然后，右边窗口的其余部分留为空白灰色空间。
我的问题是：导致此问题的类实现中我做错了什么？
Here is a screenshot的问题，下面是用于在图片中生成GUI的代码（不好意思的配色方案，只是为了在设计/调试时使我的框架保持整齐）：
[已编辑以删除不必要的代码（在这一部分中，事实证明，要生成比我原来想象的要多的帧是必需的，所以我不能削减那么多）：]
from tkinter import *
from tkinter import ttk
class CharDbGui(Frame):
# Mage character database object
def __init__(self, root, database=None, *args, **kwargs):
Frame.__init__(self, root, *args, **kwargs)
self.root = root
### Broad layout into color-coded frames first ###
self.rowweight(range(1, 5), [10, 40, 40, 10])
self.colweight(range(1, 4), [25, 75, 25])
top_toolbar = Frame(self, bg="green", height=50, width=1)
top_toolbar.grid(row=1, column=1, columnspan=4, sticky=E+W+N+S)
leftbox = Frame(self, height=1, width=1)
leftbox.grid(row=2, column=1, rowspan=2, sticky=N+S+E+W)
midbox = Frame(self, bg="white", height=1, width=1)
midbox.grid(row=2, column=2, rowspan=2, sticky=N+S+E+W)
righttopbox = Frame(self, bg="black", height=1, width=1)
righttopbox.grid(row=2, column=3, sticky=N+S+E+W)
rightbottombox = Frame(self, bg="purple", height=1, width=1)
rightbottombox.grid(row=3, column=3, sticky=N+S+E+W)
bottombox = Frame(self, bg="orange", height=1, width=1)
bottombox.grid(row=4, column=1, columnspan=4, sticky=N+S+E+W)
entity_type_list = ttk.Treeview(leftbox)
entity_type_list.pack(expand=True, side=LEFT, fill=BOTH)
sb_etl = Scrollbar(leftbox)
sb_etl.pack(side=LEFT, fill=Y)
### Placeholder widgets ###
mainbox = Text(midbox, bg="white")
mainbox.pack(expand=True, fill=BOTH)
reserved = Text(rightbottombox, bg="purple", width=1)
reserved.pack(expand=True, fill=BOTH)
logbox = Text(bottombox, height=6, width=80, bg="orange")
logbox.pack(expand=True, fill=BOTH)
### Create buttons at upper half of right edge ###
# Create frame to contain the buttons
bwidth = 12 # button width
b1 = Button(righttopbox, text="New", width=12)
b1.grid(row=1, column=1, sticky="")
b2 = Button(righttopbox, text="Edit", width=12)
b2.grid(row=2, column=1, sticky="")
b3 = Button(righttopbox, text="Organize", width=12)
b3.grid(row=3, column=1, sticky="")
b4 = Button(righttopbox, text="Templates", width=12)
b4.grid(row=4, column=1, sticky="")
b5 = Button(righttopbox, text="Delete", width=12)
b5.grid(row=5, column=1, sticky="")
# Space buttons vertically
righttopbox.grid_rowconfigure(1, weight=1)
righttopbox.grid_rowconfigure(2, weight=1)
righttopbox.grid_rowconfigure(3, weight=1)
righttopbox.grid_rowconfigure(4, weight=1)
righttopbox.grid_rowconfigure(5, weight=1)
# add self to root
self.pack(expand=True, fill=BOTH)
def rowweight(self, index, weight):
# Adjust weight(s) of row(s).
if type(index) == int: # Singleton case
assert(type(weight) == int)
self.root.grid_rowconfigure(index, weight=weight)
else: # Range case
assert(len(index) == len(weight))
for i, w in zip(index, weight):
self.root.grid_rowconfigure(i, weight=w)
def colweight(self, index, weight):
# Adjust weight(s) of column(s).
if type(index) == int: # Singleton case
assert(type(weight) == int)
self.root.grid_columnconfigure(index, weight=weight)
else: # Range case
assert(len(index) == len(weight))
for i, w in zip(index, weight):
self.root.grid_columnconfigure(i, weight=w)
def fillDefaults(self):
# Placeholder values to test with
self.root.title("Test Database")
# Populate the list with some initial values
initvals_etl = ["Characters", "Items"]
for x in initvals_etl:
self.tree.insert('', END, x, text=str(x))
y = self.tree.insert('', END, "nums", text="Numbers")
for x in range(100):
self.tree.insert(y, END, x, text=str(x))
def launch(self):
self.root.mainloop()
if __name__ == '__main__':
root = Tk()
gui = CharDbGui(root)
root.wm_state('zoomed')
gui.launch()
然后here is a picture我想要的样子，下面是用于生成它的非类代码：

答案 0 :(得分：0)
小说在评论中对这个问题给出了正确答案：
您为根部设置了权重，但需要为框架设置权重。 将self.root.grid_columnconfigure（index，weight = weight）更改为 self.grid_columnconfigure（index，weight = weight），对于 行。
回去时，我在设计类时给东西加了“ root”，这实在是太过分了，直到注释中指出，我才注意到我已经这样做了。
