Detailed Description

An object that displays web content inside a native window.

Allows loading and displaying content of a web page or a local HTML file, accessing DOM and executing JavaScript, getting notifications about loading progress etc.

When browser is no longer needed, it must be closed through the close() method to release all the allocated memory and system resources.

The Browser instance is closed automatically when its Profile is deleted or App is terminated. If the instance represents a popup window created by JavaScript via window.open(), then JavaScript can close the instance using window.close().

Member Function Documentation

◆ activate()

virtual void molybden::Browser::activate ( )

pure virtual

Activates (brings to front) the browser window.

Restores the window from minimized state if necessary.

◆ close()

virtual void molybden::Browser::close ( )

pure virtual

Hides and destroys the browser window and releases all allocated resources including the browser instance.

The unload and beforeunload JavaScript events will be fired. The beforeunload JavaScript event will trigger a confirmation dialog asking the user if they really want to leave the page and close the browser window. If the user confirms, the browser window will be closed, otherwise the attempt to close the browser window will be canceled.

If the browser window is already closed, then this method does nothing.

◆ create() [1/2]

static std::shared_ptr< Browser > molybden::Browser::create ( std::shared_ptr< App > app )

static

Creates a new browser instance.

Parameters

app	the application of the new browser.

◆ create() [2/2]

static std::shared_ptr< Browser > molybden::Browser::create ( std::shared_ptr< Profile > profile )

static

Creates a new browser instance.

Parameters

profile the profile of the new browser.

◆ download()

virtual void molybden::Browser::download ( const std::string & url )

pure virtual

Initiates a download of the resource identified by the given URL.

If the given URL is valid and points to a downloadable resource, then the download process will be started. To control the download process, use the onStartDownload delegate.

The method does nothing if the given URL is invalid or points to a resource that cannot be downloaded.

Parameters

url	the URL of the resource to download.

◆ enterFullScreen()

virtual void molybden::Browser::enterFullScreen ( )

pure virtual

Sets the browser window to full screen.

Does nothing if the browser window is not shown or it's already running in full screen mode.

◆ executeJavaScript() [1/2]

virtual JsValue molybden::Browser::executeJavaScript ( const std::string & script )

pure virtual

Executes the given script in the main frame of this browser and returns the result of the execution.

This method blocks the current thread execution and waits until the passed JavaScript code has been executed completely. The time required to complete the execution can be different depending on the passed JavaScript code. So, it is strongly recommended that the method is not invoked in the application UI thread.

Equivalent to mainFrame()->executeJavaScript(script).

Parameters

script a string that represents JavaScript code to execute.

Returns: the result of the execution.

◆ executeJavaScript() [2/2]

virtual void molybden::Browser::executeJavaScript	(	const std::string &	script,
		std::function< void(JsValue)>	callback
	)

pure virtual

Executes the given script in the main frame of this browser and returns the result of the execution.

This method does not block the current thread execution and executes the given JavaScript code asynchronously.

Equivalent to mainFrame()->executeJavaScript(script, callback).

Parameters

script	a string that represents JavaScript code to execute.
callback	a callback you can use to get the result of the execution.

◆ exitFullScreen()

virtual void molybden::Browser::exitFullScreen ( )

pure virtual

Brings the browser window out of full screen mode.

Does nothing if the browser window is not shown or it's not running in full screen mode.

◆ loadUrl()

virtual void molybden::Browser::loadUrl ( const std::string & url )

pure virtual

Starts a navigation to the resource identified by the given url.

Tells browser to start asynchronous loading and returns immediately. There is no guarantee that the resource will be loaded completely, by the time this method returns. If there is a pending navigation, it will be stopped/canceled.

Parameters

url	the URL of the resource to load. It can be the URL of a web page (e.g. https://teamdev.com/molybden) or absolute path to a local file (e.g. file:///Users/me/index.html)

◆ setBounds()

virtual void molybden::Browser::setBounds ( const Rect & bounds )

pure virtual

Sets the browser window's size and location on screen.

Parameters

bounds the bounds on screen.

◆ setTitle()

virtual void molybden::Browser::setTitle ( const std::string & title )

pure virtual

Updates the browser window title.

By default, the window title corresponds to the title of the currently loaded web page.

To reset the window title to the default one, simply set an empty title.

Parameters

title the new window title.

◆ setWindowDisplayPolicy()

virtual void molybden::Browser::setWindowDisplayPolicy ( WindowDisplayPolicy policy )

pure virtual

Specifies the policy for displaying the window across multiple desktops.

This functionality is available on macOS only. On Windows and Linux the method does nothing.

◆ setWindowTitlebarVisible()

virtual void molybden::Browser::setWindowTitlebarVisible ( bool visible )

pure virtual

Configures visibility of the browser window title bar.

When the window title bar is hidden the window becomes a full size content window. The hidden title bar does not draw its background, allowing all buttons to show through, and "click through" to happen.

On macOS the window will still have the standard window buttons ("traffic lights") in the top left and the window title in the top center. To hide the standard window buttons use setWindowButtonVisible(bool). To hide the window title use setWindowTitleVisible().

◆ title()

virtual std::string molybden::Browser::title ( )

pure virtual

Returns the current browser window title.

By default, the window title corresponds to the title of the currently loaded web page.

◆ windowDisplayPolicy()

virtual WindowDisplayPolicy molybden::Browser::windowDisplayPolicy ( )

pure virtual

Returns the policy for displaying the window across multiple desktops.

This functionality is available on macOS only. On Windows and Linux the method returns WindowDisplayPolicy::kDefault.
