Can you help me fix a problem with buttons? My layout looks like this (pic-1): BoxLayout->GridLayout->GridLayout->Button(x9)
My problem is that I cant change the text of the buttons in other sub-grids. Have a look at my idea of doing that:
Classes:
class SmallGrid(GridLayout):
buttons = []
def __init__(self, **kwargs):
super().__init__(**kwargs)
for i in range(0, 9):
obj = SudokuButton()
self.buttons.append(obj)
self.add_widget(obj)
class BigGrid(GridLayout):
small_grids = []
def __init__(self, **kwargs):
super().__init__(**kwargs)
for i in range(0, 9):
obj = SmallGrid()
self.grids.append(obj)
self.add_widget(obj)
Small part of my main class/pseudocode:
big_grid = BigGrid()
for i in range(0, 9):
for j in range(0, 9):
self.big_grid.small_grids[i].buttons[j].text = ...
I can get access to other SmallGrid() layous and their buttons but it looks like the SmallGrids() are in the same place, but their buttons are in their destinated place.

CodePudding user response：
The problem is that you are using class variables for grids and buttons. You really need them to be instance variables. Just change your definitions slightly to:
class BigGrid(GridLayout):
# grids = []
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.grids = []
for i in range(0, 9):
obj = SmallGrid()
self.grids.append(obj)
self.add_widget(obj)
and
class SmallGrid(GridLayout):
# buttons = []
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.buttons = []
for i in range(0, 9):
obj = SudokuButton()
self.buttons.append(obj)
self.add_widget(obj)
