A library to store and restore window sizes and positions for your Electron app
Heavily influenced by the implementation in electron-boilerplate.
$ npm install --save electron-window-state
const windowStateKeeper = require('electron-window-state');
let win;
app.on('ready', function () {
// Load the previous state with fallback to defaults
let mainWindowState = windowStateKeeper({
defaultWidth: 1000,
defaultHeight: 800
});
// Create the window using the state information
win = new BrowserWindow({
'x': mainWindowState.x,
'y': mainWindowState.y,
'width': mainWindowState.width,
'height': mainWindowState.height
});
// Let us register listeners on the window, so we can update the state
// automatically (the listeners will be removed when the window is closed)
// and restore the maximized or full screen state
mainWindowState.manage(win);
});
Note: Don't call this function before the ready
event is fired.
defaultWidth
- Number
The width that should be returned if no file exists yet. Defaults to 800
.
defaultHeight
- Number
The height that should be returned if no file exists yet. Defaults to 600
.
path
- String
The path where the state file should be written to. Defaults to
app.getPath('userData')
file
- String
The name of file. Defaults to window-state.json
maximize
- Boolean
Should we automatically maximize the window, if it was last closed
maximized. Defaults to true
fullScreen
- Boolean
Should we automatically restore the window to full screen, if it was last
closed full screen. Defaults to true
const windowState = windowStateKeeper({
defaultWidth: 1000,
defaultHeight: 800
});
x
- Number
The saved x
coordinate of the loaded state. undefined
if the state has not
been saved yet.
y
- Number
The saved y
coordinate of the loaded state. undefined
if the state has not
been saved yet.
width
- Number
The saved width
of loaded state. defaultWidth
if the state has not been
saved yet.
height
- Number
The saved heigth
of loaded state. defaultHeight
if the state has not been
saved yet.
isMaximized
- Boolean
true
if the window state was saved while the the window was maximized.
undefined
if the state has not been saved yet.
isFullScreen
- Boolean
true
if the window state was saved while the the window was in full screen
mode. undefined
if the state has not been saved yet.
manage(window)
- Function
Register listeners on the given BrowserWindow
for events that are
related to size or position changes (resize
, move
). It will also restore
the window's maximized or full screen state.
When the window is closed we automatically remove the listeners and save the
state.
unmanage
- Function
Removes all listeners of the managed BrowserWindow
in case it does not
need to be managed anymore.
saveState(window)
- Function
Saves the current state of the given BrowserWindow
. This exists mostly for
legacy purposes, and in most cases it's better to just use manage
.
