python - Storing frames in list -


i'm trying store frames in list can widgets 3 3 on top of each other whit small space in between them

but can't seem make work.

code:

self.cbocombo = [] self.frame_type = [] x in range(7):    self.cbocombo.append([])       y in range(3):          self.cbocombo[x].append([])          in range(7):    self.frame_type.append(i)    self.frame_type[i] = frame(self.frame_type)    self.frame_type[i].pack(side=top, expand=1, ipady= 11)    self.cbocombo[i][0] = ttk.combobox(self.frame_type[i], values=self.valcombo,             textvariable=self.varcombo[1][0])    self.cbocombo[i][0].pack(padx= 5)    self.cbocombo[i][1] = ttk.combobox(self.frame_type[i], values=self.valcombo, textvariable=self.varcombo[1][1])    self.cbocombo[i][1].pack(padx= 5)    self.cbocombo[i][2] = ttk.combobox(self.frame_type[i], values=self.valcombo, textvariable=self.varcombo[1][2])    self.cbocombo[i][2].pack(padx= 5)

error message:

  file "file.py", line 89, in __init__     self.frame_type[i] = frame(self.frame_type)   file "c:\python27\lib\lib-tk\tkinter.py", line 2453, in __init__     widget.__init__(self, master, 'frame', cnf, {}, extra)   file "c:\python27\lib\lib-tk\tkinter.py", line 1965, in __init__     basewidget._setup(self, master, cnf)   file "c:\python27\lib\lib-tk\tkinter.py", line 1943, in _setup     self.tk = master.tk attributeerror: 'list' object has no attribute 'tk'

is there solution or way done?

thanks

following tkinter docs:

w = frame ( master, option, ... )  parameters:     master: represents parent window.

your self.frame_type doesn't object represents parent window.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
