I have a CListCtrl in "List" view mode and I can't get it to scroll vertically instead of horizontally.
I've tried the suggesting here: Vertical Scrollbar in CListCtrl but that only works when using the icon view mode. It doesn't work in list mode.
So, how can I get my CListCtrl in list view mode to scroll vertically?
Have you tried this?

In the below screenshots (taken from the Apple Developer app), we can see that the Account button sticks to the bottom of the sidebar.
When the window is tall enough (left), the list doesn’t scroll, Account button’s background color has no difference. When the window is not tall enough (right), causing the list to scroll, Account button changes its background color to reveal the relationship.
The list's scroll position can not be probed. How can I declare the Account button in SwiftUI?
That app is a UIKit catalyst app and the sidebar uses scrollViewDidScroll which uses the contentSize to set a bottomButtonState which is passed into a child UIHostingController (so the account button can be SwiftUI) which I would assume switches between a clear or solid background.
We cant get the scroll info in SwiftUI however a possible workaround would be to add dummy 1 pixel high cell to the bottom of the list and using its onAppear to set a binding that is used in a bottom view to enable/disable a background colour and should achieve the same effect.
I have a Viewer contained inside a QFrame like this:
The white area is Viewer and grey area is QFrame.
What is want to have is another QscrollArea with the Viewer layed out vertically with a vertical splitter like this:
But even after selecting both QScrollArea and Viewer and then clicking the layout vertically in splitter button. The splitter does not appear? Any idea as to how to achieve this?
This is the answer you're looking for:

On a not layed out area, add the children widgets, select them with CTRL key pressed and then lay them out using a vertical splitter (there's a button on the layout toolbar above the form preview)
Assuming that by "viewer" you mean a QListView for example, i had no problem to define this using Qt Designer. You should select the QFrame and the QScrollArea from the object inspector and then click on the vertical splitter layout inside Qt Designer.
Here is the result :

Hope this helps.

->After inserting the items in listview control,i have set vertical scroll bar but i get it as horizontal scroll bars.how to solve this also?
someone help me to achieve these tasks.

Please see this set of window styles suitable for LVS_LIST:
List-View Window Styles
What about border color - consider LVS_OWNERDRAWFIXED.
And extended styles - Extended List-View Styles
Yet you can subclass window procedure for this control to manage LVM_GETITEMRECT, LVM_GETITEMPOSITION, LVM_SETITEMPOSITION messages differently.
And have a look over: NM_CUSTOMDRAW (list view) notification code
Yet don't forget to call InitCommonControlsEx() function before creating the ListView window.
I've designed a toolbox control. It's inside a CDockablePane object. Since the tools inside it may need to be scrolled, I've created a CScrollView as a child of the pane and have inserted the tools inside it as children. Based on the pane size, scrollbars of the CScrollView object appear properly, but clicking on them doesn't scroll the view. It seems that they're disabled. When I use SS_NOTIFY style when creating the CScrollView, the CScrollView object receives mouse clicks, but when i don't use the style, it doesn't. But it seems that the scroll bars inside the view control don't receive clicks. When mouse hover over them, no visual effect in scroll bars appears. It seems that the scroll bars are disabled, while I've not created nor manipulate them.
What's wrong?
mouse wheel works. click on scrollbars is received by the scroll view, not by the scrollbars. inside handler, i wrote this code:
CScrollBar *pScroll = GetScrollBarCtrl(SB_VERT);
if (pScroll->GetSafeHwnd())
{
...
if is not true. this means that the scroll view has not a scroll bar, but if so, how is it shown?!
any idea?
...
since i didn't get answer, i'm going to clarify my question with a sample code:
https://dl.dropboxusercontent.com/u/4829119/930501%20-%20t3.zip
in this sample, how can i scroll my view as i do with other views like class view and file view?

Did you initialize by calling SetScrollSizes? The scroll bars are enabled only when the sizeTotal is larger than the view window size.
I have a small window where inside is horizontal QSplitter, on one side there is control widget (labels, buttons, list widget etc), on another side there is empty widget (where stuff will be painted).
But because of empty widget splitter resizes control widget to maximum and view widget to minimum. I tried to set horizontal size policy to "Minimum" for control widget and to "Expanding" for view widget and layouts, that didn't helped.
What would be right (or easiest) way to set size for controll widget to be as small as possible and view widget expand?
Looks like it was enough to set Horizontal Stretch to factor 2 for view widget size policy.
