Updates the properties for a Desktop Window Manager (DWM) thumbnail. Removes a Desktop Window Manager (DWM) thumbnail relationship created by the DwmRegisterThumbnail function. Sets the value of Desktop Window Manager (DWM) non-client rendering attributes for a window.Ĭalled by an app or framework to specify the visual feedback type to draw in response to a particular touch or pen contact.Įnables the graphical feedback of touch and drag interactions to the user.Ĭoordinates the animations of tool windows with the Desktop Window Manager (DWM). Starting with Windows 8.1, calls to DwmSetPresentParameters always return E_NOTIMPL. DwmSetPresentParameters is no longer supported. Sets the present parameters for frame composition. The taskbar can use this bitmap as a thumbnail switch target for the window or tab. Sets a static, iconic bitmap on a window or tab to use as a thumbnail representation. The taskbar can use this bitmap to show a full-sized preview of a window or tab. Sets a static, iconic bitmap to display a live preview (also known as a Peek preview) of a window or tab. Starting with Windows 8.1, calls to DwmSetDxFrameDuration always return E_NOTIMPL. DwmSetDxFrameDuration is no longer supported. Sets the number of monitor refreshes through which to display the presented frame. Notifies Desktop Window Manager (DWM) that a touch contact has been recognized as a gesture, and that DWM should draw feedback for that gesture. Retrieves the source size of the Desktop Window Manager (DWM) thumbnail.Ĭreates a Desktop Window Manager (DWM) thumbnail relationship between the destination and source windows. Starting with Windows 8.1, calls to DwmModifyPreviousDxFrameDuration always return E_NOTIMPL. DwmModifyPreviousDxFrameDuration is no longer supported. Applications on machines running Windows 7 or earlier can listen for composition state changes by handling the WM_DWMCOMPOSITIONCHANGED notification.Ĭhanges the number of monitor refreshes through which the previous frame will be displayed. Obtains a value that indicates whether Desktop Window Manager (DWM) composition is enabled. Retrieves the current value of a specified Desktop Window Manager (DWM) attribute applied to a window.Ĭalled by an application to indicate that all previously provided iconic bitmaps from a window, both thumbnails and peek representations, should be refreshed. This function was part of an experimental feature that was never implemented in Windows. Retrieves the current composition timing information for a specified window. Retrieves the current color used for Desktop Window Manager (DWM) glass composition. This compensates for very complex scenes or calling processes with very low priority. Issues a flush call that blocks the caller until the next present, when all of the Microsoft DirectX surface updates that are currently outstanding have been made. 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.Įxtends the window frame into the client area. (DwmDetachMilContent)Įnables the blur effect on a specified window.Įnables or disables Desktop Window Manager (DWM) composition.
