我在使用带有 Tkinter 和 Python 的网格正确排列所有内容时遇到了一些麻烦。我想让菜单栏在最顶部,然后是两个列表框(每侧一个),在窗口中间有几个按钮。
目前,两个列表框都出现在窗口的右下角,按钮位于左上角,与菜单按钮重叠。
考虑到它们的大小,如何处理列表框的网格布局。它们可以占据多个网格单元吗?例如,如果我在 (row=1, column = 1) 中放置一个列表框,在行 (row = 1, column = 2) 中放置另一个列表框,Tkinter 会自动加宽单元格,使其成为列表框的宽度,还是会只是重叠列表框?
def __init__(self,root):
self.frame = Frame(root, width=500)
self.frame.pack()
self.BuildMainWindow(self.frame)
self.ListboxSet = 0
self.frame.grid()
return
#displays the menu bar and options
def BuildMainWindow(self, frame):
menubar = Frame(frame,relief=RAISED,borderwidth=1)
menubar.pack()
mb_file = Menubutton(menubar,text='file')
mb_file.menu = Menu(mb_file)
mb_file.menu.add_command(label='open', command = self.openfile)
mb_file.grid(row = 1, column = 1)
mb_edit = Menubutton(menubar,text='edit')
mb_edit.menu = Menu(mb_edit)
mb_edit.grid(row=1, column = 3)
mb_file['menu'] = mb_file.menu
mb_edit['menu'] = mb_edit.menu
#upon selecting a directory from the menu and listboxes/buttons are created
def BuildListbox(self, directory):
self.listbox1 = Tkinter.Listbox()
self.listbox2 = Tkinter.Listbox()
self.listbox1.grid(row=2, column=1)
self.listbox2.grid(row=2 ,column=10)
self.listbox2.bind('<<ListboxSelect>>', lambda e:SortActions.GetWindowIndex(self,e))
self.listbox2.bind('<B1-Motion>', lambda e:SortActions.MoveWindowItem(self,e))
i = 0
for filename in sorted(os.listdir(directory)):
self.listbox1.insert(i, filename)
i = i + 1
self.bAddToListTwo = Button(self.frame, text = "->", command = lambda:SortActions.AddToListTwo(self,self.listbox1.curselection()))
self.bAddToListTwo.grid(row=5, column = 5)
self.bAddAll = Button(self.frame, text = "Add All To Playlist", command = lambda:SortActions.AddAllFiles(self))
self.bAddAll.grid(row=6, column = 5)
self.bRemoveFromListTwo = Button(self.frame, text = "Remove From Playlist", command = lambda:SortActions.RemoveFromListTwo(self,self.listbox2.curselection()))
self.bRemoveFromListTwo.grid(row=7, column = 5)
self.bSavePlaylist = Button(self.frame, text = "Save Playlist", command = lambda:SortActions.SaveList(self))
self.bSavePlaylist.grid(row=8, column = 5)
更新 - 我让它工作。正如我所怀疑的,我在初始化期间有一些奇怪的框架配置。
