PyGame 和触摸屏 [英] PyGame and touchscreen

问题描述

我制作了一个带有按钮的 pygame GUI 界面，当用户点击它们时会激活这些按钮.当我使用真正的鼠标时，GUI 运行良好，但是当我在 PITFT (https://www.adafruit.com/product/1601 )，按钮对点击没有反应(即使我使用比我的手指更硬的材料，如手写笔).

I've made a pygame GUI interface with buttons who are activated when the user click on them. The GUI works well when i'm using my real mouse but when I run the GUI on the PITFT (https://www.adafruit.com/product/1601 ), buttons do not respond to clicks ( even if i use a harder material than my finger like a stylus ).

所以问题是:Pygame 点击事件是否与 PITFT 兼容，或者是否有一种特殊"事件为它制作?

So the question is : Are Pygame click event compatible with the PITFT or are there a kind of "special" event made for it ?

这是我在代码中使用的当前鼠标事件:

Here is the current mouse event i use in my code :

def run(self):
  """Lance la boucle principale pour gérer les événements
  """
  while True:
     event = pygame.event.wait()

     if event.type == MOUSEBUTTONDOWN and event.button == 1 and not self.keep_level_2:
        self.click(event.pos)

     elif event.type == MOUSEBUTTONUP and event.button == 1:
        self.release(event.pos)`

我在网上搜索，发现要使用 PiTft，需要添加以下几行:

I shearch on the internet and found that in order to use the PiTft, you need to add the following lines :

os.environ['SDL_VIDEODRIVER'] = 'fbcon'
os.environ["SDL_FBDEV"] = "/dev/fb1"
os.environ["SDL_MOUSEDEV"] = "/dev/input/touchscreen"
os.environ["SDL_MOUSEDRV"] = "TSLIB"

所以我尝试添加它们，但触摸屏仍然没有响应.

So i've tried adding them but the touchscreen is still not responding.

另外，什么时候程序运行，我不能退出(CTRL C和escape不起作用).

Also, when to program run, i can't quit it ( CTRL C and escape don't work ).

注意:我的代码没有在 python 3 中运行

Note : My code is not running in python 3

推荐答案

您是否检查过您的/dev/input/touchscreen 是否链接"到了正确的模块?检查 evtest/dev/input/touchscreen 并检查它在使用屏幕、键盘或鼠标时是否有任何反应！

Did you check that your /dev/input/touchscreen is "linked" to the right module? Check evtest /dev/input/touchscreen and check if it does anything when using the screen, or the keyboard, or the mouse!

如果发生这种情况，您应该再次执行安装过程.

If this is happening you should follow the install procedure again.
