FormBorderStyle = FormBorderStyle. Remove the border if this is meant to be a border-less Form public partial class frmBlurBehind : Form See this other question about a DwmExtendFrameIntoClientArea() implementation. (As a note, the BlurBehind effect does not work if the Form has a white background color) No need to verify it or override WndProc to handle a DWM Composition change. The User32 function only requires the use of an internal structure, here called WinCompositionAttrData, where the Attribute member is set to DWMWINDOWATTRIBUTE.AccentPolicy and the Data member is set to the pointer of an internal structure, here called AccentPolicy, where the AccentState member is set to DWMACCENTSTATE.ACCENT_ENABLE_BLURBEHINDĭWM Compostion is always enabled. This code is using the not yet documented SetWindowCompositionAttribute() function. Here, I'm calling it from the Form's constructor. You may also want to override a Form's class WndProc when a WM_DWMCOMPOSITIONCHANGED message is received (informing of the Aero composition state), to verify whether DWM Composition is enabled.īefore showing the Window interface, call DwmEnableBlurBehindWindow(), setting its DWM_BLURBEHIND structure relevant fields ( dwFlags and fEnable) to 1. Funky Focus gives you the option to blur images using Radial mode (for a circular-shaped blur), Square mode (for a square-shaped blur), or Linear mode (perfect for when you want to blur the background or other panes such as middle ground or foreground). The Window needs to register a rendering policy with DwmSetWindowAttribute(), setting the DWMWINDOWATTRIBUTE enumerator to NCRenderingPolicy and enable it, setting the DWMNCRENDERINGPOLICY enumerator to Enabled. Step 2: Choose Your Blur Mode and Focal Point.
