Tauri Window Customization

Covers window customization in Tauri v2: custom titlebars, transparent windows, and window menus.

Configuration Methods

• tauri.conf.json - Static configuration at build time
• JavaScript Window API - Runtime modifications from frontend
• Rust Window struct - Runtime modifications from backend

Window Configuration (tauri.conf.json)

{
  "app": {
    "windows": [{
      "title": "My App",
      "width": 800,
      "height": 600,
      "decorations": true,
      "transparent": false,
      "alwaysOnTop": false,
      "center": true
    }]
  }
}

Custom Titlebar Implementation

Step 1: Disable Decorations

{ "app": { "windows": [{ "decorations": false }] } }

Step 2: Configure Permissions (src-tauri/capabilities/default.json)

{
  "identifier": "main-capability",
  "windows": ["main"],
  "permissions": [
    "core:window:default",
    "core:window:allow-start-dragging",
    "core:window:allow-close",
    "core:window:allow-minimize",
    "core:window:allow-toggle-maximize"
  ]
}

Step 3: HTML Structure

<div class="titlebar">
  <div class="titlebar-drag" data-tauri-drag-region>
    <span class="title">My Application</span>
  </div>
  <div class="titlebar-controls">
    <button id="titlebar-minimize">-</button>
    <button id="titlebar-maximize">[]</button>
    <button id="titlebar-close">x</button>
  </div>
</div>
<main class="content"><!-- App content --></main>

Step 4: CSS Styling

.titlebar {
  height: 30px;
  background: #329ea3;
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  display: grid;
  grid-template-columns: 1fr auto;
  user-select: none;
}

.titlebar-drag {
  display: flex;
  align-items: center;
  padding-left: 12px;
}

.titlebar-controls { display: flex; }

.titlebar-controls button {
  width: 46px;
  height: 30px;
  border: none;
  background: transparent;
  color: white;
  cursor: pointer;
}

.titlebar-controls button:hover { background: rgba(255,255,255,0.1); }
.titlebar-controls button#titlebar-close:hover { background: #e81123; }
.content { margin-top: 30px; padding: 16px; }

Step 5: JavaScript Controls

import { getCurrentWindow } from '@tauri-apps/api/window';

const appWindow = getCurrentWindow();

document.getElementById('titlebar-minimize')
  ?.addEventListener('click', () => appWindow.minimize());
document.getElementById('titlebar-maximize')
  ?.addEventListener('click', () => appWindow.toggleMaximize());
document.getElementById('titlebar-close')
  ?.addEventListener('click', () => appWindow.close());

Drag Region Behavior

The data-tauri-drag-region attribute applies only to its element, not children. This preserves button interactivity. Add the attribute to each draggable child if needed.

Manual Drag with Double-Click Maximize

document.getElementById('titlebar')?.addEventListener('mousedown', (e) => {
  if (e.buttons === 1 && e.target === e.currentTarget) {
    e.detail === 2 ? appWindow.toggleMaximize() : appWindow.startDragging();
  }
});

macOS Transparent Titlebar

Cargo.toml

[target."cfg(target_os = \"macos\")".dependencies]
cocoa = "0.26"

Rust Implementation

use tauri::{TitleBarStyle, WebviewUrl, WebviewWindowBuilder};

pub fn run() {
    tauri::Builder::default()
        .setup(|app| {
            let win_builder = WebviewWindowBuilder::new(app, "main", WebviewUrl::default())
                .title("Transparent Titlebar Window")
                .inner_size(800.0, 600.0);

            #[cfg(target_os = "macos")]
            let win_builder = win_builder.title_bar_style(TitleBarStyle::Transparent);

            let window = win_builder.build().unwrap();

            #[cfg(target_os = "macos")]
            {
                use cocoa::appkit::{NSColor, NSWindow};
                use cocoa::base::{id, nil};
                let ns_window = window.ns_window().unwrap() as id;
                unsafe {
                    let bg_color = NSColor::colorWithRed_green_blue_alpha_(
                        nil, 50.0/255.0, 158.0/255.0, 163.5/255.0, 1.0
                    );
                    ns_window.setBackgroundColor_(bg_color);
                }
            }
            Ok(())
        })
        .run(tauri::generate_context!())
        .expect("error while running tauri application")
}

Note : Custom titlebars on macOS lose native features like window snapping. Transparent titlebar preserves these.

Window Menus

Menu Item Types

Creating Menus (JavaScript/TypeScript)

import { Menu, MenuItem, Submenu, PredefinedMenuItem, CheckMenuItem } from '@tauri-apps/api/menu';

const fileSubmenu = await Submenu.new({
  text: 'File',
  items: [
    await MenuItem.new({
      id: 'new', text: 'New', accelerator: 'CmdOrCtrl+N',
      action: () => console.log('New')
    }),
    await MenuItem.new({
      id: 'open', text: 'Open', accelerator: 'CmdOrCtrl+O',
      action: () => console.log('Open')
    }),
    await MenuItem.new({
      id: 'save', text: 'Save', accelerator: 'CmdOrCtrl+S',
      action: () => console.log('Save')
    }),
    { type: 'Separator' },
    await MenuItem.new({
      id: 'quit', text: 'Quit', accelerator: 'CmdOrCtrl+Q',
      action: () => console.log('Quit')
    })
  ]
});

const editSubmenu = await Submenu.new({
  text: 'Edit',
  items: [
    await PredefinedMenuItem.new({ item: 'Undo' }),
    await PredefinedMenuItem.new({ item: 'Redo' }),
    await PredefinedMenuItem.new({ item: 'Separator' }),
    await PredefinedMenuItem.new({ item: 'Cut' }),
    await PredefinedMenuItem.new({ item: 'Copy' }),
    await PredefinedMenuItem.new({ item: 'Paste' })
  ]
});

const viewSubmenu = await Submenu.new({
  text: 'View',
  items: [
    await CheckMenuItem.new({
      id: 'sidebar', text: 'Show Sidebar', checked: true,
      action: async (item) => console.log('Sidebar:', await item.isChecked())
    })
  ]
});

const menu = await Menu.new({ items: [fileSubmenu, editSubmenu, viewSubmenu] });
await menu.setAsAppMenu();

Creating Menus (Rust)

use tauri::menu::{MenuBuilder, SubmenuBuilder};

let file_menu = SubmenuBuilder::new(app, "File")
    .text("new", "New")
    .text("open", "Open")
    .text("save", "Save")
    .separator()
    .text("quit", "Quit")
    .build()?;

let edit_menu = SubmenuBuilder::new(app, "Edit")
    .undo()
    .redo()
    .separator()
    .cut()
    .copy()
    .paste()
    .build()?;

let menu = MenuBuilder::new(app)
    .items(&[&file_menu, &edit_menu])
    .build()?;

app.set_menu(menu)?;

macOS Note : All menu items must be grouped under submenus. Top-level items are ignored.

Handling Menu Events (Rust)

app.on_menu_event(|_app_handle, event| {
    match event.id().0.as_str() {
        "new" => println!("New file"),
        "open" => println!("Open file"),
        "save" => println!("Save file"),
        "quit" => std::process::exit(0),
        _ => {}
    }
});

Dynamic Menu Updates

JavaScript:

const statusItem = await menu.get('status');
if (statusItem) await statusItem.setText('Status: Ready');

Rust:

menu.get("status").unwrap().as_menuitem_unchecked().set_text("Status: Ready")?;

Complete Example

main.rs

use tauri::menu::{MenuBuilder, SubmenuBuilder};

pub fn run() {
    tauri::Builder::default()
        .setup(|app| {
            let file_menu = SubmenuBuilder::new(app, "File")
                .text("new", "New")
                .text("open", "Open")
                .separator()
                .text("quit", "Quit")
                .build()?;

            let edit_menu = SubmenuBuilder::new(app, "Edit")
                .undo().redo().separator().cut().copy().paste()
                .build()?;

            let menu = MenuBuilder::new(app)
                .items(&[&file_menu, &edit_menu])
                .build()?;
            app.set_menu(menu)?;
            Ok(())
        })
        .on_menu_event(|_app, event| {
            match event.id().0.as_str() {
                "quit" => std::process::exit(0),
                id => println!("Menu event: {}", id),
            }
        })
        .run(tauri::generate_context!())
        .expect("error while running tauri application")
}
