问题 this is a bit longer, the first part is just a description of the problem, the second one the question if my "fix" is correct. I started with python programming. I created a program that communicates with an Arduino that reads the temperature of a furnace of our melting lab. The temperature is then used in a PID algorithm and an output is set to the Arduino. The communication is done via pyserial. So far, everthing works, including live plotting of the temperature signals, PID-variables and

问题 I would like to have a scrollable context menu so that I can place many Actions in it. I saw an answer from another post that setting menu.setStyleSheet('QMenu{menu-scrollable: 1;}') will enable scroll Bar but it doesn't seem to do the job.

问题 I am trying to build a simple GUI using PyQT5, with 3 buttons to open file browsers and one more to run processing with the selected files, but I can't get my buttons to connect to the functions needed to carry this out.
