guiver

An experiment in simple GUI programming with Rust: * Piet is used for rendering * (multipass) immediate mode rendering is used, inspired by egui * but also retained mode widgets with message passing are provided, inspired by Tcl/Tk

Notes

• an application implements the Application trait
• an application is in full control:
  • it handles widget events in Application::handle_widget_event()
• widgets implement the Widget trait
• the WidgetManager owns all widgets

Todo

• Layout:
  • [ ] multiple single child layout widgets or only one Container?
  • [ ] Layout Widgets need to:
  • [ ] get the Rects of all its children
    • WidgetRequest?
  • [ ] set the Rects of all its children
    • WidgetCommand
    • [ ] what about Labels? their minimum rectangle is driven by the text and the font
    • tight?
  • [ ] PaintBrush
• [ ] implement 7GUIs
  • [ ] "Counter"
  • [ ] implement Button, Row, Column, Spacer, Padding
  • [ ] "Temperature Converter"
  • [ ] implement TextEdit
  • [ ] "Flight Booker"
  • [ ] implement DropdownBox
  • [ ] "Timer"
  • [ ] "CRUD"
  • [ ] "Circle Drawer"
  • [ ] "Cells"
• [ ] allow a "no loop" optimization for static applications that only render once
• [ ] add Python bindings
• [ ] provide a WebAssembly demo
