Tagged: Virtual window interactor WPF
- 09/08/2019 at 23:58 #11863
I have a program that can create multiple wpf windows. And i want every one of them to contain a virtual window. Should i declare these variables in every one of the wpf windows?
private Host host = new Host();
private VirtualWindowsAgent virtualWindowsAgent;
Or is it a waste of ressources?

Hi @eyetrackjack and thanks for your query. There is no need to declare for each WPF window instance as we recommend you use a single host + agent per application. Therefore make the declaration within the main method.
Declaring multiple instances may have unpredictable consequences so please refrain from doing so.
Please do let us know if you are having any issues in this regard or if we can provide further information.12/08/2019 at 17:23 #11869
Thank you for the answer.
It is a WPF application and i don’t use a main routine. So, do i declare it in app.xaml.cs and access it like this?

Hi @eyetrackjack, the Main() Entry point should be located within App.Xaml.Cs -> App -> Main():Void which you can find within the Solution Explorer of Visual Studio and is automatically generated whenever a new WPF project is generated in VS. Here you go declare the Host variables. Hopefully should be clear know, please let me know otherwise.13/08/2019 at 20:56 #11874
In the examples there is always a OnStartUp and OnExit routine. In the example here https://github.com/Tobii/CoreSDK But it doesn’t show how to access the host from a different window. Ok, it is not necessary there. I will look for different examples.21/08/2019 at 21:06 #11917
Indeed, there are a few different options for the entry point including both the void:main() and OnStartup Routines, however so long as the Tobii host (and other relevant variables) is declared, there should be no difference to program functionality.
Please do let us know if we can provide any further information. Best Wishes.
