python篇-kivy-kv

1，Label

   遗留问题：加上 markup: True之后，文本不显示了

   解决方法：把text_size和color属性注释掉就出现了

kivytest.py

# coding:utf-8
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.label import Label


class KvTest(FloatLayout):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

    def label_ref(self, label):
        print('ref事件被触发了')

    def label_ref_03(self):
        print('ref_03事件被触发了')
        Label

class KvTestApp(App):
    def build(self):
        return KvTest()


if __name__ == '__main__':
    KvTestApp().run()

kivytest.kv

<KvTest>:
    Label:
        text: '[s][ref=label]AAAA[/ref][/s]'
        #font_size: '30px'
        text_size: (100, 100)
        color: (255,22,1,1)
        valign: 'top'
        # 当需要设置标记文本的时候，需要将markup设置为 True
        # markup: True
        on_ref_press:
            root.label_ref(self)
            print('这是第二个事件。。。。')
            root.label_ref_03()

 

2， TabbedPanel

  tabbedpanel.py

from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
class TabbedPanelTest(TabbedPanel):
    def __init__(self,**kwargs):
        super().__init__(**kwargs)
class TabbedPanelApp(App):
    def build(self):
        return TabbedPanelTest()
if __name__ == '__main__':
    TabbedPanelApp().run()

tabbedpanel.kv

<TabbedPanelTest>:
    size_hint:.5,.5
    pos_hint:{'center_x':.5,'center_y':.5}
    do_default_tab:False
 
    TabbedPanelItem:
        text:'first tab'
        Label:
            text:'First tab content area'
    TabbedPanelItem:
        text:'tab2'
        BoxLayout:
            Label:
                text:'Second tab content area'
            Button:
                text:'Button that dose nothing'
    TabbedPanelItem:
        text:'tab3'
        RstDocument:
            text:
                "\n".join(("Hello world","-----------","You are in the third tab."))
