Print demo home_page animate have a problem need help

[dongjian]

Hi! I'm running slint on linux (directly render to /dev/fb0 with std) (#2832) . All animations in printerdemo.slint run normally, but nothing happens when you click the button in home_page.slint. I have to switch pages at printerdemo.slint and go back home_page again. Then the correct page will appear.
I try to change

    UsbPage {
        x: root.current-subpage == 4 ? 0 : parent.width + parent.x + 2px;
        animate x { duration: 125ms; easing: ease; }
        back => { root.current-subpage = 0 }
    }

to

    UsbPage {
        x: root.current-subpage == 4 ? 0 : parent.width + parent.x + 2px;
        animate x { duration: 10ms; easing: ease; }
        back => { root.current-subpage = 0 }
    }

then it's worked,but the animation time is very short

Here is my code

struct MyPlatform {
    window: Rc<MinimalSoftwareWindow>,
}
impl Platform for MyPlatform {
    fn create_window_adapter(
        &self,
    ) -> Result<Rc<dyn slint::platform::WindowAdapter>, slint::PlatformError> {
        Ok(self.window.clone())
    }
    // optional: You can put the event loop there, or in the main function, see later
    fn run_event_loop(&self) -> Result<(), slint::PlatformError> {
        todo!();
    }
loop {
        slint::platform::update_timers_and_animations();
        window.draw_if_needed(|renderer| {
            renderer.render(&mut work_buffer, DISPLAY_WIDTH.try_into().unwrap());

            work_buffer.iter().enumerate().for_each(|(i, v)| {
                fb_buffer[i * 4] = v.b;
                fb_buffer[i * 4 + 1] = v.g;
                fb_buffer[i * 4 + 2] = v.r;
                fb_buffer[i * 4 + 3] = 255;
            });
            fb.write_frame(&fb_buffer);
        });
        if window.has_active_animations() {
            continue;
        }
        {
            let mut list = linux_touch_evnet::TOUCH_EVENT_LIST.lock().unwrap();
            if list.len() > 0 {
                let event = list.remove(0);
                window.dispatch_event(event);
                continue;
            }
        }

    }
}

I don't know where the problem is. Please help

Is it a problem with the input event not being understood? (click event not run?)
Or is it a problem with the animation not running?

Is the loop running?

Can you try to remove

       if window.has_active_animations() {
            continue;

The click event seems like no problem.
Here is the video

yes. the loop is running .

Can you try to remove

   if window.has_active_animations() {
        continue;

I tried, but nothing happened

Thanks

And I test on simulator (windows : cargo run --features simulator). there is noting wrong . Then I run on virtual machine (Unbuntu server) and had the same problem.
Test both 1.0.2 and 1.1.0
cargo.toml:

slint = { version = "1.1.0", default-features = false, features = [
    "compat-1-0",
    "unsafe-single-threaded",
    "libm",
    "std",
] }

build.rs:

    slint_build::compile_with_config(
        "ui/printerdemo.slint",
        slint_build::CompilerConfiguration::new()
            .embed_resources(slint_build::EmbedResourcesKind::EmbedForSoftwareRenderer),
    ).unwrap();

Did you make more progress in figuring out what the problem is?

I can't reproduce this on On Linux/X11 with

cargo run  -p printerdemo_mcu --features=simulator

I try to load home_page directly

fn main() {
    slint_build::compile_with_config(
        "ui/home_page.slint",
        slint_build::CompilerConfiguration::new()
            .embed_resources(slint_build::EmbedResourcesKind::EmbedForSoftwareRenderer),
    ).unwrap();
}

export component HomePage inherits Window {

And then the problem was gone. but I can not figure out why
