我目前正在创建一个非常简单的GUI应用程序,左侧需要一些按钮(在一个狭窄的窗格中),右侧需要一个matplotlib
图表(较宽的一个)。我没有Python GUI的经验,但我决定和Kivy一起去尝试这样的事情:
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
class MyApp(App):
def build(self):
layout = GridLayout(cols=2)
inLayout = GridLayout(rows=3)
inLayout.add_widget(Button(text='Function 1', width = 50))
inLayout.add_widget(Button(text='Function 2', width = 50))
inLayout.add_widget(Button(text='Function 3', width = 50))
layout.add_widget(inLayout)
layout.add_widget(Button(text='Chart pane'))
return layout
if __name__ == '__main__':
MyApp().run()
由于按钮是左窗格中唯一需要的东西,我认为可能调整所有这些按钮会缩小整个窗格,但它并没有。有没有办法做到这一点或者GridLayout中的单元格总是必须是相同的大小,无论如何?如果是这样,Kivy中是否有类似的布局允许这样的改动?
答案 0 :(得分:1)
您应该设置size_hint
个GridLayout
个孩子的属性。在这种情况下,您需要更改inLayout
对象,layout
实例的第一个子对象。要使按钮始终调整为0.2宽度的可用空间,请将其设置为(0.2, 1)
:
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
class MyApp(App):
def build(self):
layout = GridLayout(cols=2)
inLayout = GridLayout(rows=3, size_hint=(0.2, 1))
inLayout.add_widget(Button(text='Function 1'))
inLayout.add_widget(Button(text='Function 2'))
inLayout.add_widget(Button(text='Function 3'))
layout.add_widget(inLayout)
layout.add_widget(Button(text='Chart pane'))
return layout
if __name__ == '__main__':
MyApp().run()
要将固定大小的宽度设置为size_hint
到(None, 1)
并设置“width”属性:
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
class MyApp(App):
def build(self):
layout = GridLayout(cols=2)
inLayout = GridLayout(rows=3, width=100, size_hint=(None, 1))
inLayout.add_widget(Button(text='Function 1'))
inLayout.add_widget(Button(text='Function 2'))
inLayout.add_widget(Button(text='Function 3'))
layout.add_widget(inLayout)
layout.add_widget(Button(text='Chart pane'))
return layout
if __name__ == '__main__':
MyApp().run()
