Renderer architechure of composable Maui.Graphics.Controls #91

Open redradist opened 3 years ago

redradist commented 3 years ago

Hi all,

I have found this project recently and I am curious is there an architecture for rendering of Graphics Controls in this repo ?

For example Avalonia doing the something similar, they use underlying draw system, but they have composability of graphic controls and due to this they have renderer architecture (Main Thread and Renderer Thread)

Do you have already specified the renderer architecture for composable Graphic Controls ?

Such kind of architecture will allow deterministically (not relying on underlying platform) propagate event in Tree like structure of composable Controls

redradist commented 2 years ago

Looks like these controls do not allow something like in Flutter/Avalonia - Widget architecture (full UI is drawn) Do you have plans to add such support ?

jsuarezruiz commented 2 years ago

Could you share links to review what other frameworks are doing?.

redradist commented 2 years ago

Yes, of course:

  1. Uno Platform https://platform.uno/pixel-perfect
  2. Flutter https://www.youtube.com/watch?v=996ZgFRENMs, there are much more other links
  3. Avalonia UI https://youtu.be/RTXNJ0vENlA?t=1155 (video in Russian, but I hope auto-translation and timestamp will help to understand rendering mechanism)

@redradist - such a hierarchy is in MAUI itself. Would be redundant to have that here, IMHO.

The outcome I want is Maui > these Graphics.Controls > Maui.Graphics > bitmap > everywhere.

That is, instead of rendering Maui to native controls, render Maui directly to a bitmap, using this library as one of the steps.

@ToolmakerSteve I do not think it is the case in MAUI, because for Xamarin all controls was wrappers around native components and all event propagation relies on Android or iOS and it make difficult to propagate event in hierarchic components ... In contrast, in Flutter, JetPack Compose, Qt it much simpler, becaue all event propagate hierarchically and handled from child to parent

IndianaGary commented 2 years ago

Actually, Xamarin Forms had the Visual property that supported various drawn controls, such as Material, Fluent, and Cupertino. These were intended to be implemented as drawn controls that could be used on any platform. It strikes me that this project offers an alternative approach.

I'm very much n favorite of this project as it offers me a way to create some drawn controls, like custom ColorPickers and Sliders.

redradist commented 2 years ago

@jsuarezruiz Do you know something from Microsoft about implementation completely its own render system based on Microsoft.Maui.Graphics ?

Something that will draw on single canvas and works similar way it is done in Flutter, JetPack Compose (new Android approach, similar to Flutter) or Avalonia ?

Is there internal thought about it ?

I am very interested in such approach because in Xamarin I was tired of platform specific issues and due to this only platform specific features: event propagation, changing how to customize something on each platform separately, platform specific bug and due to this workaround for this particular platforms, - all it make hard to customize and support the application

@jsuarezruiz Do you know if there some people who working on such rendering mechanism ?

Because without such rendering mechanism, ф performance would be very pure for application with lots of drawn controls

Maui does not use renderers, it uses handlers. That said, Javier has a library showing how to draw controls here: https://github.com/jsuarezruiz/AlohaKit.Controls
