test.py

Question

我已经用Python（test.py）和kivy（test.kv）编写了一些代码。当我运行test.py.then show test Menu和user子菜单时。当我点击用户然后+添加按钮show.When点击+添加然后显示两个TextBox类型

我在两个（类别和名称）中使用TreeView当我从catgory TextBox中选择Male时，显示男性名称rows1 = [（＆＃39; Andrew＆＃39;），（＆＃39; Daniel＆＃39;），（＆＃39;心光＆＃39）。]
如果我从类别textBox中选择任何类别，则相同的列表显示。我希望它根据类别进行更改。

如果我从类别中选择女性，则应显示rows1 = [（＆＃39; Atarah＆＃39;），（＆＃39; Abigail＆＃39;），（＆＃39; Adriel＆＃39;）]
如果我从类别中选择Dog，则应显示rows1 = [（＆＃39; Abby＆＃39;），（＆＃39; Flash＆＃39;），（＆＃39; Penny＆＃39;）]

        Label:
            size_hint_y: 1

有人可以帮助我吗？

Answer 1

第一件事。您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词典

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': []})

然后编辑一下TreeViewEffectType类：

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)

我们需要第一个文本输入的值，因此您必须将该属性保存在kv：

中

...
<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()
