Play with window

Most of following things require node-webkit >= 0.2.4

DOM has provided some functions to create, close, resize and move windows, but due to browser's security consideration, the things you can do are much restricted. But with node-webkit, you're much free with window operations.

Create and close window

To create a window, use the familiar window.open(URL,name,specs) which is mainly used to popup ad windows in browser ;-)

Parameter meanings:

  • URL specifies the URL of the page to open, it can be a page in your app package.
  • name specifies the target attribute or the name of the window. It has no use currently.
  • specs specifies window features, screenX and screenY set new window's position, width and height set new window's size.

An example:

window.open('popup.html', '_blank', 'screenX=0,screenY=0,width=100,height=100');

To close a window, use window.close();.

Focus and blur

By using window.focus() and window.blur(), you can move focus between your windows. To focus on parent window, you can use window.opener.focus().

Move and resize window

The window.resizeTo(width,height) method resizes a window to the specified width and height.

The window.resizeBy(width,height) method resizes a window by the specified amount.

The window.moveTo(x,y) method moves a window's left and top edge to the specified coordinates.

The window.moveBy(x,y) method moves a window a specified number of pixels relative to its current coordinates.

Javascript dialogs

Traditional javascript dialogs alert, confirm and prompt are supported in node-webkit.

The alert() method displays an alert box with a specified message and an OK button.

The confirm() method displays a dialog box with a specified message, along with an OK and a Cancel button.

The prompt() method displays a dialog box that prompts the visitor for input.

Locale information

The window.navigator.language shows locale of current system, the default one is en-US if node-webkit cannot dig out locale information. You can use it to implement l10n functions.
