// I'm also assuming that there's some logic bugs in the demo application, which wasn't built with this in mind; I have a much simpler application that I'm happy to show if that would be helpful (would need to extract an example). As a rough solution, I apply the following transformation on Winit's WindowEvent::ScaleFactorChanged:
|
||||
|
||||
// /* ... in an application struct/impl ... */
|
||||
// pub fn rescale(
|
||||
// &mut self,
|
||||
// new_size: winit::dpi::PhysicalSize<u32>,
|
||||
// new_scale_factor: f64,
|
||||
// ) {
|
||||
// // Update translation
|
||||
// // (TODO: This is a guestimate and not well-tested;
|
||||
// // the size updates might turn out ot be completely unnecessary)
|
||||
// let shift = self.size.height as f32 - new_size.height as f32;
|
||||
// self.canvas.translate(0.0, -shift);
|
||||
|
||||
// // Update properties
|
||||
// self.size = new_size;
|
||||
// self.scale_factor = new_scale_factor;
|
||||
// self.canvas.set_size(
|
||||
// self.size.width,
|
||||
// self.size.height,
|
||||
// self.scale_factor as f32,
|
||||
// )
|
||||
// }
|
||||
|
||||
// With this, the canvas position and scale is preserved while the window is moved across screens, but as I'd like to apply further translations and keeping track of everything is getting very hard 😅 . I'm wondering if I'm making a mistake somewhere, or if there might be some way to do this in femto.
