Can't scroll using mouse in a terminal ?

[Adham-A]

Hello,
I can't seem to scroll using my mouse in a terminal, I tried outside and inside vscode but without success. Is it even possible or is it an issue on my computer ?

vscode ? Is that issue related to bacon ?

If it is, then yes, you should be able to use the mouse wheel to scroll the report in bacon.

I'm on Windows, and I tried in Git Bash, CMD and powershell and I still have the same issue outside of vscode this time

On Linux

• Scrolling fires the "Up" & "Down" events, same as using those buttons on the keyboard.

On Windows

• No events are fired, but there is supposed to be.

Investigations :

I tried getting Mouse Events instead of key events inside the project with no luck, I then tried in an empty project with only termimad and I didn't succeed either. I then directly tried with crossterm and it worked, firing ScrollDown & ScrollUp

After some investigation you have to :

   // Have to do this part because of crossterm
    let mut stdout = io::stdout();
    execute!(
        stdout,
        EnableMouseCapture, // termimad::crossterm::event::EnableMouseCapture
    )?;
    // Have to do this part because of crossterm`

And then match the events :

#[cfg(windows)]
Event::Mouse(mouse_event) => {
    let key_code =
    match mouse_event.kind {
        MouseEventKind::ScrollDown => {KeyCode::Down}
        MouseEventKind::ScrollUp => {KeyCode::Up}
        _ => {KeyCode::Null}
    };
    action = keybindings.get(KeyEvent::new(key_code,KeyModifiers::NONE));
}
#[cfg(not(windows))]
_ => {}

If this is going to be merged :

I created an action using Down and Up to try to stay coherent to the rest.
And I will welcome some feedback to have something cleaner especially regarding the crossterm part with EnableMouseCapture.

Thanks for the investigation. I should have rememembered this myself as I had the problem before in broot.

Regarding your code, I'll comment on the PR

Now fixed in 2.13.0

Works in normal terminals, but not in tmux. I think tmux detects if the program captures mouse events, and forwards the mouse events to the program only if so.

Probably related to the mentioned EnableMouseCapture thing.
