## Recent Documents
|
||||
|
||||
Windows and macOS provide easy access to a list of recent documents opened by
|
||||
the application via JumpList or dock menu, respectively.
|
||||
See [Recent Documents documentation](recent-documents.md).
|
||||
|
||||
__JumpList:__
|
||||
## Progress Bar
|
||||
|
||||
|
||||
See the [Progress Bar documentation](progress-bar.md).

|
||||
See the [Unity Launcher documentation](unity-launcher.md).
|
||||
|
||||
To add a file to recent documents, you can use the
|
||||
[app.addRecentDocument][addrecentdocument] API:
|
||||
## Represented File for macOS Window
|
||||
|
||||
```javascript
|
||||
const {app} = require('electron')
|
||||
app.addRecentDocument('/Users/USERNAME/Desktop/work.type')
|
||||
```
|
||||
|
||||
And you can use [app.clearRecentDocuments][clearrecentdocuments] API to empty
|
||||
the recent documents list:
|
||||
|
||||
```javascript
|
||||
const {app} = require('electron')
|
||||
app.clearRecentDocuments()
|
||||
```
|
||||
|
||||
### Windows Notes
|
||||
|
||||
In order to be able to use this feature on Windows, your application has to be
|
||||
registered as a handler of the file type of the document, otherwise the file
|
||||
won't appear in JumpList even after you have added it. You can find everything
|
||||
on registering your application in [Application Registration][app-registration].
|
||||
|
||||
When a user clicks a file from the JumpList, a new instance of your application
|
||||
will be started with the path of the file added as a command line argument.
|
||||
|
||||
### macOS Notes
|
||||
|
||||
When a file is requested from the recent documents menu, the `open-file` event
|
||||
of `app` module will be emitted for it.
|
||||
|
||||
## Custom Dock Menu (macOS)
|
||||
|
||||
macOS enables developers to specify a custom menu for the dock, which usually
|
||||
contains some shortcuts for commonly used features of your application:
|
||||
|
||||
__Dock menu of Terminal.app:__
|
||||
|
||||
<img src="https://cloud.githubusercontent.com/assets/639601/5069962/6032658a-6e9c-11e4-9953-aa84006bdfff.png" height="354" width="341" >
|
||||
|
||||
To set your custom dock menu, you can use the `app.dock.setMenu` API, which is
|
||||
only available on macOS:
|
||||
|
||||
```javascript
|
||||
const {app, Menu} = require('electron')
|
||||
|
||||
const dockMenu = Menu.buildFromTemplate([
|
||||
{label: 'New Window', click () { console.log('New Window') }},
|
||||
{label: 'New Window with Settings',
|
||||
submenu: [
|
||||
{label: 'Basic'},
|
||||
{label: 'Pro'}
|
||||
]
|
||||
},
|
||||
{label: 'New Command...'}
|
||||
])
|
||||
app.dock.setMenu(dockMenu)
|
||||
```
|
||||
|
||||
## User Tasks (Windows)
|
||||
|
||||
On Windows you can specify custom actions in the `Tasks` category of JumpList,
|
||||
as quoted from MSDN:
|
||||
|
||||
> Applications define tasks based on both the program's features and the key
|
||||
> things a user is expected to do with them. Tasks should be context-free, in
|
||||
> that the application does not need to be running for them to work. They
|
||||
> should also be the statistically most common actions that a normal user would
|
||||
> perform in an application, such as compose an email message or open the
|
||||
> calendar in a mail program, create a new document in a word processor, launch
|
||||
> an application in a certain mode, or launch one of its subcommands. An
|
||||
> application should not clutter the menu with advanced features that standard
|
||||
> users won't need or one-time actions such as registration. Do not use tasks
|
||||
> for promotional items such as upgrades or special offers.
|
||||
>
|
||||
> It is strongly recommended that the task list be static. It should remain the
|
||||
> same regardless of the state or status of the application. While it is
|
||||
> possible to vary the list dynamically, you should consider that this could
|
||||
> confuse the user who does not expect that portion of the destination list to
|
||||
> change.
|
||||
|
||||
__Tasks of Internet Explorer:__
|
||||
|
||||
|
||||
|
||||
Unlike the dock menu in macOS which is a real menu, user tasks in Windows work
|
||||
like application shortcuts such that when user clicks a task, a program will be
|
||||
executed with specified arguments.
|
||||
|
||||
To set user tasks for your application, you can use
|
||||
[app.setUserTasks][setusertaskstasks] API:
|
||||
|
||||
```javascript
|
||||
const {app} = require('electron')
|
||||
app.setUserTasks([
|
||||
{
|
||||
program: process.execPath,
|
||||
arguments: '--new-window',
|
||||
iconPath: process.execPath,
|
||||
iconIndex: 0,
|
||||
title: 'New Window',
|
||||
description: 'Create a new window'
|
||||
}
|
||||
])
|
||||
```
|
||||
|
||||
To clean your tasks list, just call `app.setUserTasks` with an empty array:
|
||||
|
||||
```javascript
|
||||
const {app} = require('electron')
|
||||
app.setUserTasks([])
|
||||
```
|
||||
|
||||
The user tasks will still show even after your application closes, so the icon
|
||||
and program path specified for a task should exist until your application is
|
||||
uninstalled.
|
||||
|
||||
## Thumbnail Toolbars
|
||||
|
||||
On Windows you can add a thumbnail toolbar with specified buttons in a taskbar
|
||||
layout of an application window. It provides users a way to access to a
|
||||
particular window's command without restoring or activating the window.
|
||||
|
||||
From MSDN, it's illustrated:
|
||||
|
||||
> This toolbar is simply the familiar standard toolbar common control. It has a
|
||||
> maximum of seven buttons. Each button's ID, image, tooltip, and state are defined
|
||||
> in a structure, which is then passed to the taskbar. The application can show,
|
||||
> enable, disable, or hide buttons from the thumbnail toolbar as required by its
|
||||
> current state.
|
||||
>
|
||||
> For example, Windows Media Player might offer standard media transport controls
|
||||
> such as play, pause, mute, and stop.
|
||||
|
||||
__Thumbnail toolbar of Windows Media Player:__
|
||||
|
||||
|
||||
|
||||
You can use [BrowserWindow.setThumbarButtons][setthumbarbuttons] to set
|
||||
thumbnail toolbar in your application:
|
||||
|
||||
```javascript
|
||||
const {BrowserWindow} = require('electron')
|
||||
const path = require('path')
|
||||
|
||||
let win = new BrowserWindow({
|
||||
width: 800,
|
||||
height: 600
|
||||
})
|
||||
|
||||
win.setThumbarButtons([
|
||||
{
|
||||
tooltip: 'button1',
|
||||
icon: path.join(__dirname, 'button1.png'),
|
||||
click () { console.log('button1 clicked') }
|
||||
},
|
||||
{
|
||||
tooltip: 'button2',
|
||||
icon: path.join(__dirname, 'button2.png'),
|
||||
flags: ['enabled', 'dismissonclick'],
|
||||
click () { console.log('button2 clicked.') }
|
||||
}
|
||||
])
|
||||
```
|
||||
|
||||
To clean thumbnail toolbar buttons, just call `BrowserWindow.setThumbarButtons`
|
||||
with an empty array:
|
||||
|
||||
```javascript
|
||||
const {BrowserWindow} = require('electron')
|
||||
let win = new BrowserWindow()
|
||||
win.setThumbarButtons([])
|
||||
```
|
||||
|
||||
## Unity Launcher Shortcuts (Linux)
|
||||
|
||||
In Unity, you can add custom entries to its launcher via modifying the
|
||||
`.desktop` file, see [Adding Shortcuts to a Launcher][unity-launcher].
|
||||
|
||||
__Launcher shortcuts of Audacious:__
|
||||
|
||||
|
||||
|
||||
## Progress Bar in Taskbar (Windows, macOS, Unity)
|
||||
|
||||
On Windows a taskbar button can be used to display a progress bar. This enables
|
||||
a window to provide progress information to the user without the user having to
|
||||
switch to the window itself.
|
||||
|
||||
On macOS the progress bar will be displayed as a part of the dock icon.
|
||||
|
||||
The Unity DE also has a similar feature that allows you to specify the progress
|
||||
bar in the launcher.
|
||||
|
||||
__Progress bar in taskbar button:__
|
||||
|
||||
|
||||
|
||||
To set the progress bar for a Window, you can use the
|
||||
[BrowserWindow.setProgressBar][setprogressbar] API:
|
||||
|
||||
```javascript
|
||||
const {BrowserWindow} = require('electron')
|
||||
let win = new BrowserWindow()
|
||||
win.setProgressBar(0.5)
|
||||
```
|
||||
|
||||
## Icon Overlays in Taskbar (Windows)
|
||||
|
||||
On Windows a taskbar button can use a small overlay to display application
|
||||
status, as quoted from MSDN:
|
||||
|
||||
> Icon overlays serve as a contextual notification of status, and are intended
|
||||
> to negate the need for a separate notification area status icon to communicate
|
||||
> that information to the user. For instance, the new mail status in Microsoft
|
||||
> Outlook, currently shown in the notification area, can now be indicated
|
||||
> through an overlay on the taskbar button. Again, you must decide during your
|
||||
> development cycle which method is best for your application. Overlay icons are
|
||||
> intended to supply important, long-standing status or notifications such as
|
||||
> network status, messenger status, or new mail. The user should not be
|
||||
> presented with constantly changing overlays or animations.
|
||||
|
||||
__Overlay on taskbar button:__
|
||||
|
||||
|
||||
|
||||
To set the overlay icon for a window, you can use the
|
||||
[BrowserWindow.setOverlayIcon][setoverlayicon] API:
|
||||
|
||||
```javascript
|
||||
const {BrowserWindow} = require('electron')
|
||||
let win = new BrowserWindow()
|
||||
win.setOverlayIcon('path/to/overlay.png', 'Description for overlay')
|
||||
```
|
||||
|
||||
## Flash Frame (Windows)
|
||||
|
||||
On Windows you can highlight the taskbar button to get the user's attention.
|
||||
This is similar to bouncing the dock icon on macOS.
|
||||
From the MSDN reference documentation:
|
||||
|
||||
> Typically, a window is flashed to inform the user that the window requires
|
||||
> attention but that it does not currently have the keyboard focus.
|
||||
|
||||
To flash the BrowserWindow taskbar button, you can use the
|
||||
[BrowserWindow.flashFrame][flashframe] API:
|
||||
|
||||
```javascript
|
||||
const {BrowserWindow} = require('electron')
|
||||
let win = new BrowserWindow()
|
||||
win.once('focus', () => win.flashFrame(false))
|
||||
win.flashFrame(true)
|
||||
```
|
||||
|
||||
Don't forget to call the `flashFrame` method with `false` to turn off the flash. In
|
||||
the above example, it is called when the window comes into focus, but you might
|
||||
use a timeout or some other event to disable it.
|
||||
|
||||
## Represented File of Window (macOS)
|
||||
|
||||
On macOS a window can set its represented file, so the file's icon can show in
|
||||
the title bar and when users Command-Click or Control-Click on the title a path
|
||||
popup will show.
|
||||
|
||||
You can also set the edited state of a window so that the file icon can indicate
|
||||
whether the document in this window has been modified.
|
||||
|
||||
__Represented file popup menu:__
|
||||
|
||||
<img src="https://cloud.githubusercontent.com/assets/639601/5082061/670a949a-6f14-11e4-987a-9aaa04b23c1d.png" height="232" width="663" >
|
||||
|
||||
To set the represented file of window, you can use the
|
||||
[BrowserWindow.setRepresentedFilename][setrepresentedfilename] and
|
||||
[BrowserWindow.setDocumentEdited][setdocumentedited] APIs:
|
||||
|
||||
```javascript
|
||||
const {BrowserWindow} = require('electron')
|
||||
let win = new BrowserWindow()
|
||||
win.setRepresentedFilename('/etc/passwd')
|
||||
win.setDocumentEdited(true)
|
||||
```
|
||||
See the [Represented File documentation](represented-file.md).
|
||||
|
||||
## Dragging files out of the window
|
||||
|
||||
For certain kinds of apps that manipulate on files, it is important to be able
|
||||
to drag files from Electron to other apps. To implement this feature in your
|
||||
app, you need to call `webContents.startDrag(item)` API on `ondragstart` event.
|
||||
|
||||
In web page:
|
||||
|
||||
```html
|
||||
<a href="#" id="drag">item</a>
|
||||
<script type="text/javascript" charset="utf-8">
|
||||
document.getElementById('drag').ondragstart = (event) => {
|
||||
event.preventDefault()
|
||||
ipcRenderer.send('ondragstart', '/path/to/item')
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
In the main process:
|
||||
|
||||
```javascript
|
||||
const {ipcMain} = require('electron')
|
||||
ipcMain.on('ondragstart', (event, filePath) => {
|
||||
event.sender.startDrag({
|
||||
file: filePath,
|
||||
icon: '/path/to/icon.png'
|
||||
})
|
||||
})
|
||||
