BrowserWindow.update()

By Opera Software

From Opera 15 onward, Opera 11 & 12’s extension format is no longer supported, and instead, we’ve switched to Chromium’s extension model. Check out our new documentation for developing extensions for Opera 15 and higher and start building your own extensions.

Description:

The update() method provides a way to update the properties of a browser window.

Parameters:

  • properties: The new properties to use for updating the window.

Syntax:

void update (BrowserWindowProperties properties)

Example:

The following example creates a button in the browser toolbar. When the button is clicked, the last focused window is detected and the width is changed to 320 pixels.

//
// The background process (e.g. index.html) 
//

// Specify the properties of the button before creating it.
var UIItemProperties = {
  disabled: false,
  title: "Window creation test",
  icon: "images/icon_18.png",
  onclick: function() {
    // Get the last focused browser window
    var thisWin = opera.extension.windows.getLastFocused();
    
    // Change the window's width to 320 pixels
    thisWin.update({width: 320});
  }
};

// Create the button and add it to the toolbar.
var button = opera.contexts.toolbar.createItem( UIItemProperties );  
opera.contexts.toolbar.addItem(button);
