# Frameless window
|
|
|
|
A frameless window is a window that has no chrome, you can find a demo at
|
|
[atom/frameless-window-demo](https://github.com/atom/frameless-window-demo).
|
|
|
|
## Create a frameless window
|
|
|
|
To create a frameless window, you only need to specify `frame` to `false` in
|
|
[BrowserWindow](browser-window.md)'s `options`:
|
|
|
|
|
|
```javascript
|
|
var BrowserWindow = require('browser-window');
|
|
var win = new BrowserWindow({ width: 800, height: 600, frame: false });
|
|
```
|
|
|
|
## Draggable region
|
|
|
|
By default, the frameless window is non-draggable. Apps need to specify
|
|
`-webkit-app-region: drag` in CSS to tell atom-shell which regions are draggable
|
|
(like the OS's standard titlebar), and apps can also use
|
|
`-webkit-app-region: no-drag` to exclude the non-draggable area from the
|
|
draggable region. Note that only rectangular shape is currently supported.
|
|
|
|
To make the whole window draggable, you can add `-webkit-app-region: drag` as
|
|
`body`'s style:
|
|
|
|
```html
|
|
<body style="-webkit-app-region: drag">
|
|
</body>
|
|
```
|
|
|
|
And note that if you have made the whole window draggable, you must also mark
|
|
buttons as non-draggable, otherwise it would be impossible for users to click on
|
|
them:
|
|
|
|
```css
|
|
button {
|
|
-webkit-app-region: no-drag;
|
|
}
|
|
```
|
|
|
|
If you're only using a custom titlebar, you also need to make buttons in
|
|
titlebar non-draggable.
|
|
|
|
## Text selection
|
|
|
|
One thing on frameless window is that the dragging behaviour may conflict with
|
|
selecting text, for example, when you drag the titlebar, you may accidentally
|
|
select the text on titlebar. To prevent this, you need to disable text
|
|
selection on dragging area like this:
|
|
|
|
```css
|
|
.titlebar {
|
|
-webkit-user-select: none;
|
|
-webkit-app-region: drag;
|
|
}
|
|
```
|
|
|
|
## Context menu
|
|
|
|
On some platforms, the draggable area would be treated as non-client frame, so
|
|
when you right click on it a system menu would be popuped. To make context menu
|
|
behave correctly on all platforms, you should never custom context menu on
|
|
draggable areas.
