Kivy/Python : 根据类别列表更改 TreeView 中的子类别列表
Kivy/Python : Change Sub Category list in TreeView according Category List
我在Python（test.py）和kivy（test.kv）中写了一些代码。当我运行 test.py.然后显示测试菜单和用户 submenu.When 我点击用户，然后点击 +Add 按钮 show.When 点击 +add 然后显示两个文本框类型
我在两个（类别和名称）中都使用 TreeView 当我 select 来自类别 TextBox 的男性然后显示男性姓名 rows1 = [('Andrew'),('Daniel'), ('Ebenezer')].
如果我 select 来自类别 textBox 的任何类别，那么相同的列表 show.I 希望它根据类别进行更改。
如果我 select 来自类别的女性，则应显示 rows1 = [('Atarah'),('Abigail'),('Adriel')]
如果我 select 来自类别的狗，那么应该显示 rows1 = [('Abby'),('Flash'),('Penny')]

有人可以帮助我吗？
第一件事。你必须为不同的类别制作不同的列表
# male name list fetch from database
rows_male = [('Andrew'),('Daniel'),('Ebenezer')]
#girl name list fetch from database
rows_girl = [('Atarah'),('Abigail'),('Adriel')]
#Dog name list fetch from database
rows_dog = [('Abby'),('Flash'),('Penny')]
然后制作一个包含每棵树的字典
treeEffectType = {'Male': [], 'Female': [], 'Dog': []}
for r in rows_male:
treeEffectType['Male'].append({'node_id': r, 'children': []})
for r in rows_girl:
treeEffectType['Female'].append({'node_id': r, 'children': []})
for r in rows_dog:
treeEffectType['Dog'].append({'node_id': r, 'children': []})
然后稍微编辑一下您的 TreeViewEffectType class:
class TreeviewEffectType(Popup):
...
def __init__(self, type, **kwargs):
super(TreeviewEffectType, self).__init__(**kwargs)
self.type = type
self.tv = TreeView(root_options=dict(text=""),
hide_root=False,
indent_level=4)
for branch in treeEffectType[self.type]:
populate_tree_view_effect_type(self.tv, None, branch)
#self.remove_widgets()
self.treeviewEffectType.add_widget(self.tv)
Clock.schedule_once(self.update, 1)
...
def filter(self, f):
self.treeviewEffectType.clear_widgets()
self.tv = TreeView(root_options=dict(text=""),
hide_root=False,
indent_level=4)
new_tree = []
for n in treeEffectType[self.type]:
if f.lower() in n['node_id'].lower():
new_tree.append(n)
for branch in new_tree:
populate_tree_view_effect_type(self.tv, None, branch)
self.treeviewEffectType.add_widget(self.tv)
我们将需要第一个文本输入的值，因此您必须将 属性 保存在 kv:
...
<AccountGroupPopup>:
title: ""
size_hint: None, None
size: 500, 350
auto_dismiss: False
name_label: name_label
name_txt: name_txt
category_text: category_text
...
最后编辑您的 AccountGroupPopup：
...
class AccountGroupPopup(Popup):
category_label = ObjectProperty(None)
category_text = ObjectProperty(None)
name_label = ObjectProperty(None)
name_txt = ObjectProperty(None)
popupGroupAccount = ObjectProperty(None)
popupEffect = {}
...
def __init__(self, obj, **kwargs):
super(AccountGroupPopup, self).__init__(**kwargs)
self.mode = obj.mode
if obj.mode == "Add":
self.col_data[0] = ''
self.col_data[1] = ''
self.col_data[2] = ''
self.col_data[3] = 'Select Category'
self.col_data[4] = 'Select Name'
self.popupEffect['Male'] = TreeviewEffectType('Male')
self.popupEffect['Male'].popup5 = self
self.popupEffect['Female'] = TreeviewEffectType('Female')
self.popupEffect['Female'].popup5 = self
self.popupEffect['Dog'] = TreeviewEffectType('Dog')
self.popupEffect['Dog'].popup5 = self
...
def display_effect_type(self, instance):
if len(self.category_text.text) > 0:
if self.popupEffect[self.category_text.text] is None:
self.popupEffect[self.category_text.text] = TreeviewEffectType(self.category_text.text)
self.popupEffect[self.category_text.text].popup5 = self
self.popupEffect[self.category_text.text].filter(instance.text)
self.popupEffect[self.category_text.text].open()
我在Python（test.py）和kivy（test.kv）中写了一些代码。当我运行 test.py.然后显示测试菜单和用户 submenu.When 我点击用户，然后点击 +Add 按钮 show.When 点击 +add 然后显示两个文本框类型
我在两个（类别和名称）中都使用 TreeView 当我 select 来自类别 TextBox 的男性然后显示男性姓名 rows1 = [('Andrew'),('Daniel'), ('Ebenezer')].
如果我 select 来自类别 textBox 的任何类别，那么相同的列表 show.I 希望它根据类别进行更改。
如果我 select 来自类别的女性，则应显示 rows1 = [('Atarah'),('Abigail'),('Adriel')]
如果我 select 来自类别的狗，那么应该显示 rows1 = [('Abby'),('Flash'),('Penny')]

有人可以帮助我吗？
第一件事。你必须为不同的类别制作不同的列表
# male name list fetch from database
rows_male = [('Andrew'),('Daniel'),('Ebenezer')]
#girl name list fetch from database
rows_girl = [('Atarah'),('Abigail'),('Adriel')]
#Dog name list fetch from database
rows_dog = [('Abby'),('Flash'),('Penny')]
然后制作一个包含每棵树的字典
treeEffectType = {'Male': [], 'Female': [], 'Dog': []}
for r in rows_male:
treeEffectType['Male'].append({'node_id': r, 'children': []})
for r in rows_girl:
treeEffectType['Female'].append({'node_id': r, 'children': []})
for r in rows_dog:
treeEffectType['Dog'].append({'node_id': r, 'children': []})
然后稍微编辑一下您的 TreeViewEffectType class:
class TreeviewEffectType(Popup):
...
def __init__(self, type, **kwargs):
super(TreeviewEffectType, self).__init__(**kwargs)
self.type = type
self.tv = TreeView(root_options=dict(text=""),
hide_root=False,
indent_level=4)
for branch in treeEffectType[self.type]:
populate_tree_view_effect_type(self.tv, None, branch)
#self.remove_widgets()
self.treeviewEffectType.add_widget(self.tv)
Clock.schedule_once(self.update, 1)
...
def filter(self, f):
self.treeviewEffectType.clear_widgets()
self.tv = TreeView(root_options=dict(text=""),
hide_root=False,
indent_level=4)
new_tree = []
for n in treeEffectType[self.type]:
if f.lower() in n['node_id'].lower():
new_tree.append(n)
for branch in new_tree:
populate_tree_view_effect_type(self.tv, None, branch)
self.treeviewEffectType.add_widget(self.tv)
我们将需要第一个文本输入的值，因此您必须将 属性 保存在 kv:
...
<AccountGroupPopup>:
title: ""
size_hint: None, None
size: 500, 350
auto_dismiss: False
name_label: name_label
name_txt: name_txt
category_text: category_text
...
最后编辑您的 AccountGroupPopup：
...
class AccountGroupPopup(Popup):
category_label = ObjectProperty(None)
category_text = ObjectProperty(None)
name_label = ObjectProperty(None)
name_txt = ObjectProperty(None)
popupGroupAccount = ObjectProperty(None)
popupEffect = {}
...
def __init__(self, obj, **kwargs):
super(AccountGroupPopup, self).__init__(**kwargs)
self.mode = obj.mode
if obj.mode == "Add":
self.col_data[0] = ''
self.col_data[1] = ''
self.col_data[2] = ''
self.col_data[3] = 'Select Category'
self.col_data[4] = 'Select Name'
self.popupEffect['Male'] = TreeviewEffectType('Male')
self.popupEffect['Male'].popup5 = self
self.popupEffect['Female'] = TreeviewEffectType('Female')
self.popupEffect['Female'].popup5 = self
self.popupEffect['Dog'] = TreeviewEffectType('Dog')
self.popupEffect['Dog'].popup5 = self
...
def display_effect_type(self, instance):
if len(self.category_text.text) > 0:
if self.popupEffect[self.category_text.text] is None:
self.popupEffect[self.category_text.text] = TreeviewEffectType(self.category_text.text)
self.popupEffect[self.category_text.text].popup5 = self
self.popupEffect[self.category_text.text].filter(instance.text)
self.popupEffect[self.category_text.text].open()
