DotNetBrowser
1.21.5
|
Represents Chromium engine instance that you can use in BrowserView to display web pages, load web pages, listen to the browser events such as 'title change', 'frame start loading', 'frame finish loading', 'render gone' etc. Each Browser instance is running in a separate native process and communicates with the .NET process via Inter-Process-Communication bridge. When you don't need to use Browser instance you must dispose it using its IDisposable.Dispose method. If you dispose browser instance, you will not be able to use it anymore. To create a new Browser instance use BrowserFactory.Create() method. More...
Inherits IDisposable.

Represents Chromium engine instance that you can use in BrowserView to display web pages, load web pages, listen to the browser events such as 'title change', 'frame start loading', 'frame finish loading', 'render gone' etc. Each Browser instance is running in a separate native process and communicates with the .NET process via Inter-Process-Communication bridge. When you don't need to use Browser instance you must dispose it using its IDisposable.Dispose method. If you dispose browser instance, you will not be able to use it anymore. To create a new Browser instance use BrowserFactory.Create() method.

| Task<bool> DotNetBrowser.Browser.Dispose | ( | bool | checkBeforeUnload | ) |
Disposes the current Browser instance asynchronously with invoking the DotNetBrowser.DialogHandler.OnBeforeUnload(UnloadDialogParams) method if the webpage contains the
onbeforeunload event and checkBeforeUnload is set to true.
If checkBeforeUnload parameter is true and current document has the
method implemented, Browser engine will initiate displaying before unload confirmation dialog to ask user whether current document should be closed and current thread execution will be blocked until the DotNetBrowser.DialogHandler.OnBeforeUnload(UnloadDialogParams) method is completed. By default the DotNetBrowser.DialogHandler.OnBeforeUnload(UnloadDialogParams) method is executed in UI thread. Therefore, you should not call the Task.Wait() method of the returned Task in the UI thread to avoid deadlock.
If user cancels closing current document, the Browser instance will not be disposed. If current document doesn't have the
method implemented or user confirms closing current document, the Browser instance will be disposed.
Note, that if the DialogHandler field of current Browser instance is set to null and current document does have the
method implemented, the Browser instance will not be disposed.
Note, that Browser instance will always be disposed if customer haven't performed any actions with document before this method is invoked, e.g. focused, clicked, etc.
If current Browser instance is disposed, the method returns the task with the result value which is set to true.
