我想在.kv文件中构建以下简单设计。
它由3部分组成:
这三个部分本身都包含在AnchorLayout中。
我试图将这种设计转换为.kv文件,如下所示。
#:kivy 1.11.1
<Example>:
anchor_x: "center"
anchor_y: "center"
AnchorLayout:
anchor_x: "left"
anchor_y: "top"
size_hint: (0.2, 0.75)
GridLayout:
cols: 3
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
AnchorLayout:
anchor_x: "right"
anchor_y: "top"
size_hint: (0.8, 0.75)
BoxLayout:
orientation: "vertical"
Label:
text: "HELLO..."
Label:
text: "WORLD..."
AnchorLayout:
anchor_x: "left"
anchor_y: "bottom"
size_hint: (1, 0.25)
Label:
text: "FOOTER"
如果有关系,这也是我的.py文件的代码。
# Importing Kivy
import kivy
kivy.require("1.11.1")
# Importing kivy libraries
from kivy.app import App
from kivy.uix.anchorlayout import AnchorLayout
from kivy.lang import Builder
# Importing external libraries
# Import kv files
Builder.load_file("example.kv")
# Root widget of the application
class Example(AnchorLayout):
pass
# Application class
class TestApp(App):
def build(self, **kwargs):
return Example()
# Launch the application
if __name__=="__main__":
app = TestApp()
app.run()
输出看起来不像我期望的那样,如下图所示:
我不明白。因为AnchorLayout是Widget类的子类,并且本身包含在Layout中,所以它的size_hint属性应该使我能够定义其大小。
我在这里想念什么?预先感谢!

更改Example
类以扩展FloatLayout
而不是AnchorLayout
可以更好地控制其子级。更改为Example
之后,这是一个kv
,看起来更像您想要的内容:
<Example>:
AnchorLayout:
anchor_x: "center"
anchor_y: "top"
size_hint: (0.2, 0.75)
pos_hint: {'x':0, 'top':1}
GridLayout:
cols: 3
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
Button:
text: "X"
AnchorLayout:
anchor_x: "center"
anchor_y: "top"
size_hint: (0.8, 0.75)
pos_hint: {'right':1, 'top':1}
BoxLayout:
orientation: "vertical"
Label:
text: "HELLO..."
Label:
text: "WORLD..."
AnchorLayout:
anchor_x: "center"
anchor_y: "bottom"
size_hint: (1, 0.25)
pos_hint: {'x':0, 'y':0}
Label:
text: "FOOTER"

设计被放置在中心。
根是<Window x:Class="Contacts_App.View.NewContactWindow"

mc:Ignorable="d"
Title="New Contact Window" Height="250" Width="350">
<Window.Resources>
<vm:NewContactViewModel x:Key="vm"/>
</Window.Resources>
<Grid>
<StackPanel
Margin="10">
<Label Content="Name" />
<TextBox

Margin="0,0,0,5"/>
<Label Content="Email" />
<TextBox
Text="{Binding Source={StaticResource vm}, Path=Contact.Email, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Margin="0,0,0,5"/>
<Label Content="Phone Number" />
<TextBox

<Button

Command="{Binding Source={StaticResource vm}, Path=SaveNewContactCommand}"/>
</StackPanel>
</Grid>
</Window>
和$('.tablesorter').trigger('removeWidget', ['scroller'])
的值为'center'
的{{3}}。因此,其所有子项(anchor_x
)都相对于根放置。
下面是您的设计以不同颜色显示的视图,用于可视化。
AnchorLayout 将其子级与边框(上,下,左,右)或中心对齐。
您的设计有三种可能的解决方案。首选项是方法1。
anchor_y
s 此方法将所有AnchorLayout
替换为AnchorLayout
。它使用少了一个AnchorLayout
小部件,这使该应用程序的资源利用效率更高,即使用更少的内存并且该应用程序更小。
BoxLayout
AnchorLayout
为根此方法用<Example>:
orientation: 'vertical'
BoxLayout:
...
GridLayout: # left box
...
BoxLayout: # right box
...
BoxLayout: # footer
...
替换根窗口小部件,然后重新对齐左框。
BoxLayout
此方法将BoxLayout
作为根的子级,其余<Example>:
orientation: 'vertical'
AnchorLayout:
...
GridLayout: # left box
...
AnchorLayout: # right box
...
AnchorLayout: # footer
...
作为BoxLayout
的子级。
