问题 I am using kivy for UI. there is a Time_consuming function and when it runs, kivy ui will goes in black, so I used Threading. I want to disable buttons until Time_consuming function finishes, and then enable button again. I have been used something like below: from threading import Thread from kivy.clock import Clock from functools import partial def run(): self.run_button.disabled=True self.back_button.disabled=True t=Thread(target=Time_consuming(), args=()) t.start() Clock.schedule_interval

Bind a function to multiple dynamically created buttons in kivy?

由 依然范特西╮ 提交于 2020-01-14 05:01:21
问题 Problem I want to create multiple buttons and bind them to a function. The problem is that whenever I click on one button, the function is called multiple times. It seems to be a problem with the event connection. When I look at the instance that called the function when I pressed a button, it seems that the function gets called from every button at once?! KV Code: ... # This is the button that I'am using <ProjectSelectButton>: height: 35 background_color: 0,0,1,1 on_touch_down: self.click_on

How to hide python code file and other related files in a kivy project

问题 I have recently published an Android application on Google Play written in Python/Kivy. Normally the "build.py" script would wrap the whole project files into one single folder that is the application package folder. But if i check the content of this package on my phone after the installation of the apk i can find the "android.txt" file, the ".kv/.kv~" file and the ".py~"* and * "pyo" files. My question is: is this safe to expose the source code files or is there something that i am missing

Kivy之Video控件播放远程RTSP流

由 人走茶凉 提交于 2020-01-13 19:19:07
软件版本 Python: 3.7.3 OS: Win7 Kivy: 1.11.1 VLC: 3.0.8 简要介绍 VLC中，RTSP是基于UDP协议开发的 1 ，服务端进行串流，客户端可以播放其视频流。Kivy的Video控件是基于Gstream开发的，能够解析各种格式的视频。 步骤 第一步，服务端VLC串流 点击VLC选项卡 媒体 -> 流 -> 文件 -> 添加 -> 串流 -> 下一个 -> 目标设置 ，选择 RTSP 并点假 添加 按钮。 输入 play ，作为其访问路径 接着进行 流输出 设置，选择编码方式为 H.264 ，输出格式为 MP3(MP4) 点击 下一个 ，接着点击 流 即可 结果就是这个样子的 第二步，客户端播放RTSP流 如下代码即可创建一个播放RTSP流的客户端视频控件 filename = 'rtsp://192.168.0.100:8554/play' video = Video ( source = filename , play = 'True' , pos = ( 0 , 120 ) , volume = 0.8 ) 其效果是下图所示 图中上部分呈现的就是播放服务端的视频流。下部分是调用的本机摄像头视频实时流。 结论 Kivy有相当多的成熟的控件供开发者使用，很简单地调用即可完成开发。 https://www.cnblogs.com
