我正在研究一种GridLayout（在这里称为CostosInput），当按下按钮时，它会向自身添加TextInputs。但是，这样做时，布局不会调整其周围小部件的大小，一旦添加了一定数量的TextInput小部件，该布局便会重叠。我该如何解决？
它是另一个GridLayout的一部分，该ScrollView具有一列并包含在Label中。它下面的小部件（与之重叠的小部件）是Layouts。
我尝试查看Kivy文档，但发现的唯一内容与Widgets和layout_hint_with_bounds(sh_sum, available_space, min_bounded_size, sh_min_vals, sh_max_vals, hint)的大小有关，而不一定与它们的位置有关。我以为它类似于CostoInput (link to the Kivy docs)，但这是一个内部函数。如果某些不符合约定，我深表歉意。
这是class CostosInput(GridLayout):
def __init__(self, *args, **kwargs):
super(CostosInput, self).__init__()
self.cols = 2
self.spacing = 5
self.padding = 5
self.size_hint_y = 0.2
# used in add_lines()
self.count = 1
add = Orange_Button(text='AGREGAR COSTO')
add.bind(on_press=self.add_lines)
rem = Orange_Button(text='QUITAR COSTO')
rem.bind(on_press=self.del_lines)
self.add_widget(add)
self.add_widget(rem)
self.add_widget(Orange_Label(text='concepto'))
self.add_widget(Orange_Label(text='costo'))
self.add_lines()
# this function is adds TextInputs
# when the add button is pressed
def add_lines(self, *args, **kwargs):
text = Normal_TI()
text.text = 'costo ' + str(self.count)
text.bind(text=self.change)
flot = FloatInput()
flot.bind(text=self.change)
self.add_widget(text)
self.add_widget(flot)
self.size_hint_y += 0.1
self.count += 1
# this has nothing to do with the ui
def del_lines(self, *args, **kwargs):
for x in range(0, len(self.children) - 4, 2):
if len(self.children) > 4:
try:
if self.children[x].focus or self.children[x + 1].focus:
self.remove_widget(self.children[x])
self.remove_widget(self.children[x])
except Exception as err:
print('del lines: no se pudieron quitar,'
'err {}'.format(err))
# this also has nothing to do with the ui
def change(self, value, *args):
dicto = dict()
for x in range(0, len(self.children) - 4, 2):
dicto[self.children[x + 1].text] = self.children[x].text
print(dicto)
producto.costos = dicto
类的代码。
class Orange_Label(Label):
def __init__(self, *args, **kwargs):
super(Orange_Label, self).__init__(*args, **kwargs)
self.size_hint_y = None
self.size = (self.width, 10)
self.color = (0.95668627451, 0.6941176471, 0.5137254902, 1)
这是实例化标签的类的代码。文本属性是唯一更改的部分。
onClick={()=> this.render_detail_options(share, model)}.
