I want to design this view in swiftui but i am unable to create the leading line bar.
I am using recursive call to call the child views but the line is not extending as per requirement.

I'm building a SwiftUI app for macOS, then I came with the following challenge.
Given a view hierarchy like:
Which basically shows a collection of elements in ElementListView. Then the FiltersView is used to search new elements to possibly add to the element list, the results of that search are shown in rows like FilterRow.
When a user clicks on FilterRow, that means I want to add a new element to the ElementListView, but I am not sure of How to propagate events between the two branches of the view hierarchy in SwiftUI?
If I were to implement this in pure AppKit, I would probably use the responder chain, but I guess it's not the SwiftUI way of doing it.
You can have a shared ObservableObject for filters and list views. As soon as ObservableObject changes SwiftUI updates views connected to it.
I have a multiple view SDI project. One of the views has to be split, probably with CSplitterWnd or CSplitterWndEx. But the other views should not be split, and should not have the split buttons and scrollbars. I tried various combinations using CSplitterWnd and some classes derived from it which I found online, but I can't get what I need. So here are the constraints:
One view is CViewUnsplit, without splitter
The second view displays initially only CViewSplitLeft
A command allows the user to split/unsplit and add or remove CViewRight.
It should work in the following way.
The first is CViewUnsplit is just the way a simple SDI application comes up.
The second switched view can be easily achived in just swapping the view. This is well documented.
The basics are shown here in this sample with two views

The third is a little tricky. Just create the splitter and place the CViewSplitLeft with SetParent into the left splitter part. The right view can always stay in the splitter. Again here the splitter is just hidden in the main window. When you switch back to another view just Use SetParent again and move the CViewSplitLeft to the CMainFrame.
Always just hide all unneeded views.
Take care about the IDs of the views as shown in the sample. Otherwise the resizing will not work.
My application has a list view (master) containing a data sheet view in a sub view element.
In the list view, I would like to use some control like a button or a combo box to filter the data in the sub view. How can I pass a parameter for the filter from the master view to the sub view?
I don't believe the scenario you are looking at here will be directly possible within the Access web app context. Let me explain.
In Access 2013 web apps, there is no macro action available to requery or refresh a specific control on a view. The same goes for trying to refresh a Subview control on a view. The only way you can pass parameters to a different view in the web app context is by using the OpenPopup macro action. In that case the view will open as a popup which is not what you want here either.
So you might not be able to achieve your end goal. One suggestion that might work is to have say an unbound text box control on the main parent view. For the Subview control, use that unbound control as the Master Field (in the property list). Access will attempt to match records from this unbound control to whatever field you designate as the Child Field property. If you update that unbound text box control on the main view, Access should filter the results in the Subview. I "think" that will work.
It works in my app. SubForm updates with filter when focus leaves the txtbox. Unfortunately, you can only search one field per subview as it is set as a property at design time and AFAIK there is no way to change at runtime.
Is there an example of a mixin that implements a child view that are common to several view of an application. For example, I like to add a toolbar to every part of my application and to avoid to duplicate the toolbar element in my views template, I'd like to use mixins
Check out the layout property on Ember.View. You can have a shared layout template across the views.

You could also potentially achieve something like this using Ember.ContainerView. Your classes could add views to the childViews array.

I have 2 CView-derived classes, CThumbView and CMainView. The CThumbView class displays thumbnails of images and the CMainView class controls the View that displays the original image.
I want to display the first thumbnail and its original when my application starts up. I tried using OnInitialUpdate, but that is not the ideal way as it bothered the other functionalities that was handling the main view.
How can I do this by sending a user-defined message between the 2 views?
Since you are using the Document View Architecture you need to take advantage of the CDocument::UpdateAllViews function of the document from your view in order to update rest of the views. This function will call OnUpdate of each view.
The data is held by the document. Views access the data & update themselves accordingly.
