kandi X-RAY | arcadehid Summary
STM32 HID device for arcade builds. Compound HID device containing keyboard, mouse, two joysticks and a virtual com port. Plug into a retropie or something and wire cool buttons and joysticks and whatnot. See /cad - here you’ll find a reference design with 26 pins for an STM32F1 128kB flash variant. Any STM32F1 board would do, as long as pin-headers are broken out. Each pin can be configured with combinations of a keyboard keypress, mouse movement or click, or joystick movement or button press. Every pin can hold up to eight different combinations. There is also ternary support meaning a pin’s config can change depending on if another pin is active or not. Accelerators for mouse and joystick are supported. Everything is configured in the command line interface, either via UART pins or via virtual com port. Different configurations can be saved and loaded, using the internal flash of the STM32F1 (128 kb variant) - no extra storage chip needed. Depends on pellepl/generic_embedded and pellepl/niffs. Now also with the Annoyatron support, drive your friends mad….

type before writing it.

QUESTION
I'm coding a little tool that displays the key presses on the screen with Tkinter, useful for screen recording.
Is there a way to get a listener for all key presses of the system globally with Tkinter? (for every keystroke including F1, CTRL, ..., even when the Tkinter window does not have the focus)
I currently know a solution with pyHook.HookManager()
, pythoncom.PumpMessages()
, and also solutions from Listen for a shortcut (like WIN+A) even if the Python script does not have the focus but is there a 100% tkinter
solution?
Indeed, pyhook
is only for Python 2, and pyhook3
seems to be abandoned, so I would prefer a built-in Python3 / Tkinter solution for Windows.

QUESTION
I have a Form with a MenuStrip, where i want to react to "CTRL + P" keystrokes.
The problem is, if the MenuStrip is opened, my Form doesnt get "CTRL + P".
I tried setting Form's KeyPreview = true, and overriding ProcessCmdKey without success...
There is my ProcessCmdKey override:
...ANSWER
Answered 2022-Mar-08 at 11:29The message doesn't go through the Form's key events and it will be handled by each dropdown.
You can use the approach which is mentioned in the comments, or as another option, you can implement IMessageFilter to capture the WM_KEYDOWN before it dispatches to the dropdown:
QUESTION
I have a TextField in a view that looks something like this:
...ANSWER
Answered 2022-Mar-03 at 20:24Simply set your @FocusState
to true
in .onAppear
and wrap it in a DispatchQueue.main.asyncAfter
. The delay is needed because the view has to be on screen before the @FocusState
is changed or it won't work.

QUESTION
In flutter,
How can a parent widget know if a child among many children widgets has received focus? For example, Can we know if a child in a
Row
widget's children has received focus?Can I detect this focus before the child widget receives it?
ANSWER
Answered 2022-Feb-17 at 16:29It actually depends on your take and which architecture you wanna follow. This snippet that I'm posting uses NotificationListener, a custom notification and a custom child widget. This might work for an application like a print or a callback, but you might need to change the architecture and use a state management tool to achieve greater things.

QUESTION
I have a layout where each item in a LazyColumn
can display an item-specific dialog. The Dialogs
showed and worked fine except for some of the larger ones where whenever I would try to edit text in one of the dialog's TextFields
it would trigger the dialog to disappear.
I tried a lot of different approaches and the weirdest thing was that the dialog works fine and allows me do edit the textfields if I only scroll the LazyColumn
by even 1 item before attempting to show the dialog.
It has proven hard to reproduce the issue in a simple setting as changing even basic elements of my code makes the bug disappear but I finally managed. The appearance of the bug seems to depend on the LazyColumn
being Scrollable
and on the KeyBoard to be of type text. Next a somewhat long code sample and a GIF showing the issue:
ANSWER
Answered 2022-Feb-11 at 12:58I am convinced this is a bug that needs fixing by google however the simple solution is to add the state argument to the LazyColumn as shown.
