#AUTO HIDE SCROLLBAR WINDOWS 10 CODE#
The template class CSnapFloatingWindowImpl is implementing all events and logic associated with the floating window and is derived from CSnapWindowMover.Ĭopy Code SNAPCONTEXT* AddSnappableWindow(HWND hWndView) The template class CSnapWindowMover is used in the floating and snapping window implementations and contains the logic for moving the window and shifting its state depending on location. The classes CSnapWindowInfo, CSnapTrackInfo are used to manage state while tracking the mouse move events while in window drag mode. Well, this decision didn't make moving any easier, since the outer size of the window now is changing depending on the snapping context or if the window is floating. I thought that would be helpful in case the view is based on a dialog. I decided to keep the size of the internal window constant, the view that is. If the window now is dragged and snapped to the upper left position, it is equally important to keep the upper left position of the window in the same position independent of state. When dragging the window to a floating position, it is important that the lower right corner stays in the same position independent of window state.
#AUTO HIDE SCROLLBAR WINDOWS 10 UPDATE#
The trick was to move the reference point and update the offset depending on which side the window is snapped to.Į.g., when snapped to the bottom right corner, the lower right corner of the window is the reference point. In doing so, I store the starting point of the cursor and the offset to a reference point on the window. After many failing attempts, I now manage the dragging of the windows myself. One of the harder issues to solve was the dragging of windows between snapping positions and between snapped and floating state. #define WM_SNAP_QUERYSIZE SNAP_MSGBASE + 7 #define WM_SNAP_UPDATELAYOUT SNAP_MSGBASE + 6 #define WM_SNAP_REPOSITION SNAP_MSGBASE + 5 #define WM_SNAP_MOVEDONE SNAP_MSGBASE + 4 #define WM_SNAP_QUERYRECT SNAP_MSGBASE + 3 The following custom Windows messages are defined for the framework: Knowledge about this structure is not important when using this framework, but for extending it.

SNAPCONTEXT* is a pointer to the snapping context structure, will be NULL if not successful HWND hWndView is the view to be snappable (any window) SNAPCONTEXT* AddSnappableWindow(HWND hWndView) HWND hWndClient is the client view whose edge the views are snapping to Hides the view independently if it is snapped or floating.ĬSnappingWindow member details: void SetClient(HWND hWndClient) Sets the client window whose edge to snap to. and provides the API for adding and positioning snappable views. It is responsible for updating positions when the frame is resized etc. ReferenceĬSnappingWindow is the main window used for managing the snappable views. Although this code is written from scratch, his framework got me started. Thanks to Bjarke Viksoe for his docking framework. So here is the implementation of a snappable tool window (snaps to the sides of a view window) that also provides auto-hide and pinning features, see the picture above. I'd like to share my first attempt at adding tool windows like the ones you can find in applications like MS Visio. See How the demo was built further down in this article.
