Overview of the Desktop Window Manager (DWM) technology.
To develop Desktop Window Manager (DWM), you need these headers:
For programming guidance for this technology, see:
DWM_SHOWCONTACT Specifies the input operations for which visual feedback should be provided. |
DWM_SOURCE_FRAME_SAMPLING Flags used by the DwmSetPresentParameters function to specify the frame sampling type. |
DWM_SYSTEMBACKDROP_TYPE Flags for specifying the system-drawn backdrop material of a window, including behind the non-client area. |
DWM_TAB_WINDOW_REQUIREMENTS This enumeration supported an experimental feature that was never implemented in Windows. It has no effect and should not be used. |
DWM_WINDOW_CORNER_PREFERENCE The DWM_WINDOW_CORNER_PREFERENCE enumeration (dwmapi.h) specifies the rounded corner preference for a window. |
DWMFLIP3DWINDOWPOLICY Flags used by the DwmSetWindowAttribute function to specify the Flip3D window policy. |
DWMNCRENDERINGPOLICY Flags used by the DwmSetWindowAttribute function to specify the non-client area rendering policy. |
DWMTRANSITION_OWNEDWINDOW_TARGET Identifies the target. |
DWMWINDOWATTRIBUTE Flags used by the DwmGetWindowAttribute and DwmSetWindowAttribute functions. |
GESTURE_TYPE Identifies the gesture type specified in DwmRenderGesture. |
DwmAttachMilContent This function is not implemented. (DwmAttachMilContent) |
DwmDefWindowProc Default window procedure for Desktop Window Manager (DWM) hit testing within the non-client area. |
DwmDetachMilContent This function is not implemented. (DwmDetachMilContent) |
DwmEnableBlurBehindWindow Enables the blur effect on a specified window. |
DwmEnableComposition Enables or disables Desktop Window Manager (DWM) composition. |
DwmEnableMMCSS Notifies the Desktop Window Manager (DWM) to opt in to or out of Multimedia Class Schedule Service (MMCSS) scheduling while the calling process is alive. |
DwmExtendFrameIntoClientArea Extends the window frame into the client area. |
DwmFlush Issues a flush call that blocks the caller until the next call to a Present method, when all of the Microsoft DirectX surface updates that are currently outstanding have been made. This compensates for very complex scenes or calling processes with very low priority. |
DwmGetColorizationColor Retrieves the current color used for Desktop Window Manager (DWM) glass composition. |
DwmGetCompositionTimingInfo Retrieves the current composition timing information for a specified window. |
DwmGetGraphicsStreamClient This function is not implemented. (DwmGetGraphicsStreamClient) |
DwmGetGraphicsStreamTransformHint This function is not implemented. (DwmGetGraphicsStreamTransformHint) |
DwmGetTransportAttributes Retrieves transport attributes. |
DwmGetUnmetTabRequirements This function was part of an experimental feature that was never implemented in Windows. It has no effect and should not be used. |
DwmGetWindowAttribute Retrieves the current value of a specified Desktop Window Manager (DWM) attribute applied to a window. |
DwmInvalidateIconicBitmaps Called by an application to indicate that all previously provided iconic bitmaps from a window, both thumbnails and peek representations, should be refreshed. |
DwmIsCompositionEnabled Obtains a value that indicates whether Desktop Window Manager (DWM) composition is enabled. Applications on machines running Windows 7 or earlier can listen for composition state changes by handling the WM_DWMCOMPOSITIONCHANGED notification. |
DwmModifyPreviousDxFrameDuration Changes the number of monitor refreshes through which the previous frame will be displayed. DwmModifyPreviousDxFrameDuration is no longer supported. Starting with Windows 8.1, calls to DwmModifyPreviousDxFrameDuration always return E_NOTIMPL. |
DwmQueryThumbnailSourceSize Retrieves the source size of the Desktop Window Manager (DWM) thumbnail. |
DwmRegisterThumbnail Creates a Desktop Window Manager (DWM) thumbnail relationship between the destination and source windows. |
DwmRenderGesture Notifies Desktop Window Manager (DWM) that a touch contact has been recognized as a gesture, and that DWM should draw feedback for that gesture. |
DwmSetDxFrameDuration Sets the number of monitor refreshes through which to display the presented frame. DwmSetDxFrameDuration is no longer supported. Starting with Windows 8.1, calls to DwmSetDxFrameDuration always return E_NOTIMPL. |
DwmSetIconicLivePreviewBitmap Sets a static, iconic bitmap to display a live preview (also known as a Peek preview) of a window or tab. The taskbar can use this bitmap to show a full-sized preview of a window or tab. |
DwmSetIconicThumbnail Sets a static, iconic bitmap on a window or tab to use as a thumbnail representation. The taskbar can use this bitmap as a thumbnail switch target for the window or tab. |
DwmSetPresentParameters Sets the present parameters for frame composition. DwmSetPresentParameters is no longer supported. Starting with Windows 8.1, calls to DwmSetPresentParameters always return E_NOTIMPL. |
DwmSetWindowAttribute Sets the value of Desktop Window Manager (DWM) non-client rendering attributes for a window. |
DwmShowContact Called by an app or framework to specify the visual feedback type to draw in response to a particular touch or pen contact. |
DwmTetherContact Enables the graphical feedback of touch and drag interactions to the user. |
DwmTransitionOwnedWindow Coordinates the animations of tool windows with the Desktop Window Manager (DWM). |
DwmUnregisterThumbnail Removes a Desktop Window Manager (DWM) thumbnail relationship created by the DwmRegisterThumbnail function. |
DwmUpdateThumbnailProperties Updates the properties for a Desktop Window Manager (DWM) thumbnail. |
DWM_BLURBEHIND Specifies Desktop Window Manager (DWM) blur-behind properties. Used by the DwmEnableBlurBehindWindow function. |
DWM_PRESENT_PARAMETERS Specifies Desktop Window Manager (DWM) video frame parameters for frame composition. Used by the DwmSetPresentParameters function. |
DWM_THUMBNAIL_PROPERTIES Specifies Desktop Window Manager (DWM) thumbnail properties. Used by the DwmUpdateThumbnailProperties function. |
DWM_TIMING_INFO Specifies Desktop Window Manager (DWM) composition timing information. Used by the DwmGetCompositionTimingInfo function. |
MilMatrix3x2D Specifies a 3x2 matrix that describes a transform. |
UNSIGNED_RATIO Defines a data type used by the Desktop Window Manager (DWM) APIs. It represents a generic ratio and is used for different purposes and units even within a single API. |
