When the mouse moves during a drag, we ask HandleDragMouseMove to figure out what to do.Showing the top 5 NuGet packages that depend on 32: HANDLE_MSG(hwnd, WM_MOUSEMOVE, OnMouseMove) void OnMouseMove(HWND hwnd, int x, int y, UINT keyFlags) The autoscroll rate is traditionally based on the user’s double-click time, because that is a general indicator of how fast the user’s reaction time is.Īll that’s left is hooking things up. If it did, then we start the autoscroll timer otherwise we cancel it. When the mouse moves when we are dragging, we ask the TryAutoScroll function to perform any necessary autoscroll. void HandleDragMouseMove(HWND hwnd, POINT pt) And we let the caller know whether we performed any scrolling. If it is below the bottom, then scroll down. If the mouse is above the top of the window, then scroll up. The TryAutoScroll function actually performs the autoscroll operation if applicable. When the left button is released, we exit drag mode. HANDLE_MSG(hwnd, WM_LBUTTONUP, OnLButtonUp) void OnLButtonUp(HWND hwnd, int x, int y, UINT keyFlags) If so, then we capture the mouse (allowing us to receive mouse activity even if the mouse moves outside the window), and remember that we are dragging. Change Power Supply to Make USB Drive Recognizable Windows 10. Click 'Start' to check errors on your partition. In the Check File System window, check the 'Try to fix errors if found' option. When the user presses the left mouse button, we check to see if it is the start of a drag operation. Right-click the target partition that has a problem. HANDLE_MSG(hwnd, WM_LBUTTONDOWN, OnLButtonDown) void OnLButtonDown(HWND hwnd, BOOL fDoubleClick, int x, int y, UINT keyFlags) If we are asked to cancel whatever we’re doing, then we stop dragging by releasing the capture, and then we also cancel any autoscroll. HANDLE_MSG(hwnd, WM_CANCELMODE, OnCancelMode) Future versions of this program will eventually put more stuff here, but we’ll just start with this. Right now, all we need to do to cancel autoscroll is to cancel the autoscroll timer. This global variable keeps track of whether we have captured the mouse for dragging and possibly autoscrolling. This lets the user perform a drag-selection of content larger than the window. The idea behind autoscrolling is that if the user drags the mouse out of the window, then the window starts scrolling, continuing until the mouse returns inside the window.

The X is very tall, and the scroll bar lets you see the full height.

For further discussion of this code, go back to the scroll bars series that started this blog. Start with the scratch program and first add this code for basic scroll bar support. There are quite a few subtleties here, so I’m going to start with a basic implementation and then dig into it. Many windows perform autoscroll on drag, typically for the purpose of allowing you to drag-select a region of the window that is larger than the current client area.
