Probably the best place to start. If you look at the production Dev Panel, you should see an "Example Dev Panel" on it. If you click it, you'll launch a really simple GUI whose entire function is to print what it's doing. If you look in the example subdirectory, you'll see example.ui and example.py, which together make up that simple GUI. I created example.ui using designer in the exact same way we created our dev panels in the tutorial. The difference here is that the button on opsDevPanel.ui is a shell script button instead of a related display button, and it runs the command "pydm example/example.py" (you can open it up in designer to see). If you look at example.py, you'll see the format for a PyDM GUI:
- Blue: The name of your GUI (and file – whatever name you choose for your GUI, the python file should be [name].py)
Green: The names you gave the UI elements in

designer. Note that PyQt is an actual thing out in the google-able world

; I literally googled "pyqt button pressed" to try to figure out how to get the "someone clicked this button" signal and connect it to something
- Red: The custom functions for that GUI! It can be anything you want, this is just an example of a GUI that prints out what you're doing, but you could make a GUI that calculates power or something
Anything not in a box is boilerplate and should be present in any PyDM GUI.
