Strange effect when creating a ListView

Question

I have noticed a strange effect when I create a Listview.

When I create a ListView without also creating a Button, the selected item in the ListView have a dotted border. However, when I also create a Button, the ListView selected item don't have a dotted border anymore. This only happens when I have a manifest file that enables common controls 6:

This is the code I used to create the Window and ListView and Button:

// Create Window
HWND hWnd = CreateWindowEx(0, "WinClass", "My Window", WS_OVERLAPPEDWINDOW, 261, 172, 394, 284, NULL, NULL, hInstance, NULL);

// Create ListView
HWND hListView = CreateWindowEx(0, WC_LISTVIEW, "", WS_CHILD | LVS_REPORT | WS_VISIBLE, 0, 0, 232, 190, hWnd, 0, GetModuleHandle(NULL), NULL);

// Create Button
HWND hButtonRefresh = CreateWindowEx(NULL, "BUTTON", "OK", WS_CHILD | WS_VISIBLE | BS_DEFPUSHBUTTON, 10, 200, 110, 25, hWnd, NULL, GetModuleHandle(NULL), NULL);

Note: I don't have a problem with this effect, I just want to understand why it is happening!

Answer 1

It's just because the button has the focus and the list view lost it, click on the list view and the dots should reappear.
