I run button demo from https://github.com/beckus/stm32_p103_demos on qemu-stm32 https://github.com/beckus/qemu_stm32
I can see LED blinking in led_blink demo as text "Led ON" in the console but how do I emulate a button press?
Try using the button_int demo.
From https://github.com/beckus/stm32_p103_demos/blob/master/README:
button_int -
Example of external interrupts. Toggles the LED every time the
button is pressed. Note that in QEMU, the button press is simulated
by pressing the b key. You will need to do this from the QEMU monitor,
by typing the command "sendkey b".
According to the readme, the button demo doesn't always work:
button -
Example of using the button in non-interrupt mode. Continuously polls
the button and toggles the LED when the button is pressed. Note that this
example does not seem to work well in QEMU. When using "sendkey b"
(see the button_int demo below), the LED does not toggle. Perhaps
this is a timing issue?

I have Googled this extensively and have got nowhere.
When I press the up button in VS Code for Mac, instead of taking me to the previous line, it sometimes, randomly, shifts focus to other areas, like the terminal, the notification symbol (bottom right), and file browser.

I can display a hover popup with ⌘K ⌘I (on Mac). Is there a way to trigger a button on the popup (such as Quick Fix... in the image below) without using the mouse?
I don't know about other actions, but specifically for Quick Fix... there is a keyboard shortchut.
On a Mac it is ⌘.
So I just installed Visual Studio Code, and there's one issue that I'm having which is putting me off using it at all. Whenever I press my mouse buttons (Mouse Button 4) it changes the current code tab I'm in. Because I use this button as my push to talk key for TeamSpeak, it makes it an issue when I want to code. Is there a way to fix this? Thanks in advance.
I'm using GTK on Linux. (Both GTK2 and GTK3 exhibit this behavior.)
When you grab the window on some free space or menubar, the window itself gets dragged.
I'm using the window as a giant OpenGL canvas, and this prevents the primary mouse button presses from ever reaching the window. Double-clicks and secondary button presses arrive just fine.
How do I disable or work around this behavior? I've also tried adding a GtkDrawingArea to the window, but it still gets dragged.
This is not possible. GTK overrides the function of primary mouse button unconditionally. However, simply adding an empty GtkLabel to the window worked just well for me.
Edit: eventually I just used a GtkDrawingArea, because I also wanted a scroll/menubar. That works just as well.
Gtk does grab unconditionally, but you have full control of what that specific "click" will do.
Returning True from any "button-xxx" method will stop further processing from Gtk. See "Return type" here.
I have an external mouse which also register a HID keyboard in Device Manager. One of its button shows start menu. I want to replace it with mouse click. Since I also have an inbuilt keyboard I don't want to replace its start button. I want to replace start button from the external mouse
Try using the #InstallKeybdHook and look in the KeyHistory when you have pressed the button!
This can atleast tell you if your mouse button has the same virtual key code or scan code as the built-in keyboards key
