Window Frameless

Window Frameless

Wails menyediakan dukungan window frameless dengan region drag berbasis CSS dan perilaku platform-native. Hapus title bar native platform untuk kontrol penuh atas chrome window, desain kustom, dan pengalaman pengguna unik sambil mempertahankan fungsionalitas penting seperti dragging, resizing, dan kontrol sistem.

Mulai Cepat

window := app.Window.NewWithOptions(application.WebviewWindowOptions{
    Title:     "Frameless App",
    Width:     800,
    Height:    600,
    Frameless: true,
})

CSS for draggable title bar:

.titlebar {
    --wails-draggable: drag;
    height: 40px;
    background: #333;
}

.titlebar button {
    --wails-draggable: no-drag;
}

HTML:

<div class="titlebar">
    <span>My Application</span>
    <button onclick="window.close()">×</button>
</div>

That’s it! You have a custom title bar.

Membuat Window Frameless

Window Frameless Dasar

window := app.Window.NewWithOptions(application.WebviewWindowOptions{
    Frameless: true,
    Width:     800,
    Height:    600,
})

What you get:

  • No title bar
  • No window borders
  • No system buttons
  • Transparent background (optional)

What you need to implement:

  • Draggable area
  • Close/minimise/maximise buttons
  • Resize handles (if resizable)

Dengan Background Transparan

window := app.Window.NewWithOptions(application.WebviewWindowOptions{
    Frameless:      true,
    BackgroundType: application.BackgroundTypeTransparent,
})

Kasus penggunaans:

  • Rounded corners
  • Custom shapes
  • Overlay windows
  • Splash screens

Region Drag

Dragging Berbasis CSS

Use the --wails-draggable CSS property:

/* Draggable area */
.titlebar {
    --wails-draggable: drag;
}

/* Non-draggable elements within draggable area */
.titlebar button {
    --wails-draggable: no-drag;
}

Values:

  • drag - Area is draggable
  • no-drag - Area is not draggable (even if parent is)

Contoh Title Bar Lengkap

<div class="titlebar">
    <div class="title">My Application</div>
    <div class="controls">
        <button class="minimize">−</button>
        <button class="maximize">□</button>
        <button class="close">×</button>
    </div>
</div>
.titlebar {
    --wails-draggable: drag;
    display: flex;
    justify-content: space-between;
    align-items: center;
    height: 40px;
    background: #2c2c2c;
    color: white;
    padding: 0 16px;
}

.title {
    font-size: 14px;
    user-select: none;
}

.controls {
    display: flex;
    gap: 8px;
}

.controls button {
    --wails-draggable: no-drag;
    width: 32px;
    height: 32px;
    border: none;
    background: transparent;
    color: white;
    font-size: 16px;
    cursor: pointer;
    border-radius: 4px;
}

.controls button:hover {
    background: rgba(255, 255, 255, 0.1);
}

.controls .close:hover {
    background: #e81123;
}

JavaScript for buttons:

import { Window } from '@wailsio/runtime'

document.querySelector('.minimize').addEventListener('click', () => Window.Minimise())
document.querySelector('.maximize').addEventListener('click', () => Window.Maximise())
document.querySelector('.close').addEventListener('click', () => Window.Close())

Tombol Sistem

Implementasi Close/Minimise/Maximise

Go side:

type WindowControls struct {
    window *application.WebviewWindow
}

func (wc *WindowControls) Minimise() {
    wc.window.Minimise()
}

func (wc *WindowControls) Maximise() {
    if wc.window.IsMaximised() {
        wc.window.UnMaximise()
    } else {
        wc.window.Maximise()
    }
}

func (wc *WindowControls) Close() {
    wc.window.Close()
}

JavaScript side:

import { Minimise, Maximise, Close } from './bindings/WindowControls'

document.querySelector('.minimize').addEventListener('click', Minimise)
document.querySelector('.maximize').addEventListener('click', Maximise)
document.querySelector('.close').addEventListener('click', Close)

Or use runtime methods:

import { Window } from '@wailsio/runtime'

document.querySelector('.minimize').addEventListener('click', () => Window.Minimise())
document.querySelector('.maximize').addEventListener('click', () => Window.Maximise())
document.querySelector('.close').addEventListener('click', () => Window.Close())

Toggle State Maximise

Track maximise state for button icon:

import { Window } from '@wailsio/runtime'

async function toggleMaximise() {
    const isMaximised = await Window.IsMaximised()

    if (isMaximised) {
        await Window.Restore()
    } else {
        await Window.Maximise()
    }

    updateMaximiseButton()
}

async function updateMaximiseButton() {
    const isMaximised = await Window.IsMaximised()
    const button = document.querySelector('.maximize')
    button.textContent = isMaximised ? '❐' : '□'
}

Handle Resize

Resize Berbasis CSS

Wails provides automatic resize handles for frameless windows:

/* Enable resize on all edges */
body {
    --wails-resize: all;
}

/* Or specific edges */
.resize-top {
    --wails-resize: top;
}

.resize-bottom {
    --wails-resize: bottom;
}

.resize-left {
    --wails-resize: left;
}

.resize-right {
    --wails-resize: right;
}

/* Corners */
.resize-top-left {
    --wails-resize: top-left;
}

.resize-top-right {
    --wails-resize: top-right;
}

.resize-bottom-left {
    --wails-resize: bottom-left;
}

.resize-bottom-right {
    --wails-resize: bottom-right;
}

Values:

  • all - Resize from all edges
  • top, bottom, left, right - Specific edges
  • top-left, top-right, bottom-left, bottom-right - Corners
  • none - No resize

Contoh Handle Resize

<div class="window">
    <div class="titlebar">...</div>
    <div class="content">...</div>
    <div class="resize-handle resize-bottom-right"></div>
</div>
.resize-handle {
    position: absolute;
    width: 16px;
    height: 16px;
}

.resize-bottom-right {
    --wails-resize: bottom-right;
    bottom: 0;
    right: 0;
    cursor: nwse-resize;
}

Platform-Specific Behaviour

Windows frameless windows:

window := app.Window.NewWithOptions(application.WebviewWindowOptions{
    Frameless: true,
    Windows: application.WindowsWindow{
        DisableFramelessWindowDecorations: false,
    },
})

Features:

  • Automatic drop shadow
  • Snap layouts support (Windows 11)
  • Aero Snap support
  • DPI scaling

Disable decorations:

Windows: application.WindowsWindow{
    DisableFramelessWindowDecorations: true,
},

Snap Assist:

// Trigger Windows 11 Snap Assist
window.SnapAssist()

Custom title bar height: Windows automatically detects drag regions from CSS.

Praktik Terbaik

✅ Lakukan

  • Provide draggable area - Users need to move the window
  • Implement system buttons - Close, minimise, maximise
  • Set minimum size - Prevent unusable layouts
  • Test on all platforms - Behaviour varies
  • Use CSS for drag regions - Flexible and maintainable
  • Provide visual feedback - Hover states on buttons

❌ Jangan

  • Don’t forget resize handles - If window is resizable
  • Don’t make entire window draggable - Prevents interaction
  • Don’t forget no-drag on buttons - They won’t work
  • Don’t use tiny drag areas - Hard to grab
  • Don’t forget platform differences - Test thoroughly

Troubleshooting

Window Won’t Drag

Cause: Missing --wails-draggable: drag

Solution:

.titlebar {
    --wails-draggable: drag;
}

Tombol Don’t Work

Cause: Tombol are in draggable area

Solution:

.titlebar button {
    --wails-draggable: no-drag;
}

Can’t Resize Window

Cause: Missing resize handles

Solution:

body {
    --wails-resize: all;
}
