egui_tool_windows

Floating tool windows for egui that can be used in containers, like resize, scroll-area, frame, etc.

• Simple API for adding multiple windows inside a container.
• Independent z-ordering, when clicked they are sent to the front.
• Collapsible.
• Resizable.
• Draggable.
• Floats on top of content.
• Constrained to the container.
• Clipped to the container.
• Tool windows are moved if the container is resized too small.

Regular egui::Window and egui::Area instances can be placed above them, they do not clash.

Basic API usage

egui::ScrollArea::both()
    .auto_shrink([false, false])
    .scroll_bar_visibility(ScrollBarVisibility::AlwaysVisible)
    .show(ui, |ui|{

        ui.strong("Content inside a frame");
        
        ToolWindows::new()
            .windows(ui, |builder|{
                builder
                    .add_window("id_salt_1")
                    .show("Title 1".to_string(), |ui| {
                        ui.label("Tool window 1");
                    });

                builder
                    .add_window("id_salt_2")
                    .show("Title 2".to_string(), {
                        ui.label("Tool window 2");
                    });
            });
    });

You can call ToolWindows::new() as many times as you like, e.g. if you have multiple containers that each need their own tool windows.

Status

This crate is work-in-progress, but usable, see below.

Demos

The crate contains 3 demos.

• simple - shows the current state and behavior of the tool windows when used in a container.
• inside_windows - attempts to use the tool windows inside egui::Window instances.
• inside_dock - attempts to use the tool windows inside an egui_dock, when the tabs are popped out egui::Window instances are used. This is most complicated scenario.

Refer to the demos folder.
