How to implement a scroller to one of the labels before reaching the top of the screen has remained at the top, and the text scrolls from another label beyond the limits of the screen, such as in instagramm, except instead of photos text from the second label

I am using NM_CUSTOMDRAW to draw tree view items. My items right justify parts of it by using a right margin based on the RECT area reported available. The issue I have is that when the vertical scrollbar appears or disappears, only the item expanded/collapsed and the area under the scrollbar seems to update (invalidated regions). This causes the repaint requests (with the new width) to not update the area correctly.
For example (using text and a single space as example): You could have something with the scrollbar be right justified text ## where ## is the scrollbar then when the scrollbar goes away you end up with right justified text t instead of right justified text
Is there a good way to fix this?
One thought is if I could catch a message when a scrollbar shows up or goes away, I could just invalidate the window to force a redraw. Is there such a message?
Or is there a way to add to the invalidated region without triggering a redraw loop but would update the full items area?
Another thought is I can just use the full window RECT size and use a right margin large enough that wouldn't be under the scroll area but I'd rather not do that.
Thanks!
I am trying to create app. In the form, there is only 3 button in a groupbox. I want to make the groupbox always fit in the screen. The problem is when i minimize the form, there is vertical and horizontal scroll. So i cannot see the whole groupbox border:
I want to make the groupbox to minimize without the scroll and i am able to see all the border just like when in the maximize screen as below:
I have already tried groupbox autosize to true while anchor to top, bottom, right, and left but it is still not working. Any idea how i can achieve this?
As #ib11 said you need to go to Dock and select Fill. In addition, if you want to make your group box not fill the form but grow with it, you'll probably need to change the Anchor to all sides. That's why your previous settings didn't work because anchor doesn't fill the screen, it's just a property to grow with the screen. Fill makes it possible so that you can have a group box or any other control always fill the screen.
See this image for dock:

You need to set the Dock property of the GroupBox to Fill.
Like so:
I have an app which uses EMPageViewController to display a set of onboarding slides. My understanding is that the underlying scroll view is using paged mode to display slides.
Upon update to iOS11, I see that suddenly the slides follow the finger, so they are draggable and bounce up and down. I expect paged scroll view to be scrollable horizontally only.
How can I restrict paged scroll view to horizontal scrolling only in iOS11 ?
I tried this but it did not work
pageViewController.scrollView.alwaysBounceVertical = false
This fixes the issue:
if #available(iOS 11.0, *)
{
self.scrollView.contentInsetAdjustmentBehavior = .never
}
The behavior for determining the adjusted content offsets. This
property specifies how the safe area insets are used to modify the
content area of the scroll view.
contentInsetAdjustmentBehavior is new from iOS 11 > and the default value is automatic.
Content is always adjusted vertically when the scroll view is the
content view of a view controller that is currently displayed by a
navigation or tab bar controller. If the scroll view is horizontally
scrollable, the horizontal content offset is also adjusted when there
are nonzero safe area insets.
Which made some of my UIScrollView scroll more than they were excepted to.
I'm sorry, but I can't get this working:
Scroll down the page to a certain position. Then pause scrolling and animate something. After that scroll down to the bottom of the page.
How do I make Skrollr scroll the end of the page without feeding absolute values to it?
I know the pausing demo, but that works with sections that always fill the whole window. But my section that follows the animated part is larger than that so I can't just say: change its position from -100% to 0% or something like that.
I would like to have buttons inside a scroll view (or another solution to creating a scrollable button bar).
I have buttons placed side by side in a row along the top of a view. As a user resizes the window to be less wide, fewer buttons can be seen.
When all the buttons cannot be viewed, I would like the user to still be able to access all the buttons by scrolling horizontally through them.
To visualise this, imagine in Safari if you open too many tabs to fit in the window - I would like the user to be able to scroll to the right and reveal the tabs that weren't on the screen.
You need to deselect the springs (for the custom view of the scroller) in the autosizing setter so that the view doesn't shrink along with the scroll view when you resize.
