I'm working on a WinUI3 desktop application in c++. I was trying to achieve an experience where we can show a ProgressRing in the center of the screen when there is a delay in screen update. In my application, my window has a Canvas as its content and that canvas contains many widgets. I want to put a new Canvas as an overlay on top of the existing Canvas and show a ProgressRing on the new Overlay Canvas and I was able to achieve an experience like this.
The overlay Canvas in the image has a background color as transparent, I wanted to make the overlay canvas translucent. So that all the widgets below the overlay canvas will look like grayed-out non-interactive widgets.
I would be of great help if you could help me with this issue.
Thank you,

One way to do that is to set the Background("Black" maybe?) and the Opacity depending on how you want it to look.
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 am interested in it because I need to drag the ScrolledWindow not with a scroll bar but with a mouse - press the mouse button and drag the window content (Dragging the area inside the ScrolledWindow). As I figured out it is possible with the help of enabling the check box (touch screen simulation) in the inspector, but the problem is that I need to enable this check box every time I run the application.
I am developing a desktop app using MFC. The following image shows the current state of the app's window top part. The area marked in red is unnecessary and I want to remove it.
How can I remove that space or atleast change the color to match the rest of the window background?
More Info:
The App is using Ribbon UI. I have added the App button programmatically in onCreate of CMainFrame. Is it the bar that holds the Ribbon categories? I tried SetMenubarState(AFX_MVS_HIDDEN) thinking it was the menu bar, but that didn't work. Just changing its color is also acceptable.
Update:
I have managed to change the color of that ribbon strip, and removed the caption bar I used for showing the 'add' button. Now I need to figure out how to place the 'Add' button on the right side of the ribbon strip.
Could somebody tell me how to erase a rectangle that has just been drawn on an image?
In the application, I have an image displayed on a document (MDI application). The user can select a portion of the image. I implemented this feature as letting the user start the selection with a CRectTrackerColor (derived from CRectTracker) object. The selection works fine: a user is able select a rectangle using the mouse. A rubber band rectangle is shown as a feedback. After the user releases the left mouse, the rectangle is colored based on my pen color. Then I present a dialog for OK/Cancel. Upon Cancel, I would like the rectangle to disappear. How should I go about doing that?
Thanks.
Just invalidate that rectangle so it'll get redrawn normally.
