C++ TCP server Integration correct use of NotifyEvent Subscription
I'm trying to integrate old MFC styled TCP IOCPServer with noesisgui IntegrationGLUT example .
There are no examples of doing so and i'm very confused how to correctly work/use Noesis::INotify , INotifyPropertyChanged for it.
As i need somehow tell to gui - ListBox that data has to be inserted .
In old fashioned way After Socket Read Data, i'm calling a CALLBACK* NOTIFYPROC function with data and packeID on stack like so
That is executing/Notifying MainFrame of MFC ui.
and inside this function i'm accessing global variables - View's
and depending on the Code value
I'm sending Data to the ListCtrl of g_view1.
How can i do this in NoesisGui - Access xaml item's/Views(Like TabItem, ListBox) of static Noesis::IView* _view ?
Create a Notify/Subscription , something like this where itemsSource = pData And FilterPredicate is TabItem1::OnAddToList i guess ?

switch (Code)

case CONNECT:
g_View1 ->PostMessage(WM_ADDTOLIST, 0, (LPARAM)pData);

notify->CollectionChanged() += MakeDelegate(this, &FilterPredicate::OnItemsChanged);

I assume you read the DataBinding tutorial, did you?
Re: C++ TCP server Integration correct use of NotifyEvent Subscription
Yes i did and i read https://www.noesisengine.com/docs/Gui.C ... Guide.htmlI assume you read the DataBinding tutorial, did you?
with this example
Code: Select all
Slider* slider = view->GetContent()->FindName<Slider>("Luminance");
slider->ValueChanged() += &LuminanceChanged;I'm using IntegrationGLUT example, and need a correct way to access XAML items(TabItem, ListBox,ComboBox,etc ) -> members , so i can transmit data that was received on tcp/socket,
Re: C++ TCP server Integration correct use of NotifyEvent Subscription
You have two options:
- The recommended one is using databinding and MVVM. Almost all our examples follow this approach.
- Give names to required controls in XAML, get access to them by code using FindName and update corresponding properties,

databinding and mvvm can be used for IntegrationGLUT ?You have two options:

Yes, IntegrationGLUT is a minimal example using NoesisGUI. DataBinding is part of the core architecture of NoesisGUI.
