Note that this definition is specific to rounded corners the DwmSetWindowAttribute function is designed to take different parameters depending on the flags provided, so this is not a general-purpose signature.

This example shows how to call DwmSetWindowAttribute from C# by using the attribute. Example 1 - Rounding an app's main window in C# - WPF The following examples show how you can call DwmSetWindowAttribute or DwmGetWindowAttribute to control your app's rounding experience if your app is not rounded by policy.Įrror handling has been left out of these examples for brevity and clarity. See the Examples section for further details. All standard WinForms and WPF apps are rounded automatically, but if you customize your window frame or use a third party framework, you might need to opt-in to rounded corners.

You'll need to use your language's implementation of P/Invoke to declare the function (C# code is given in the example below). For C# appsĭwmSetWindowAttribute is a native Win32 API and is not exposed directly to. For the second parameter, which specifies which attribute you are setting, pass the DWMWA_WINDOW_CORNER_PREFERENCE value defined in the DWMWINDOWATTRIBUTE enumeration. Round the corners if appropriate, with a small radius.Ī pointer to the appropriate value from this enum is passed to the third parameter of DwmSetWindowAttribute. Let the system decide whether or not to round window corners. You specify the corner rounding option you want for your app by passing a value of the DWM_WINDOW_CORNER_PREFERENCE enumeration (shown in the following table) to the DwmSetWindowAttribute function. If your app is not rounded by policy, you can optionally use these APIs to let your app opt-in to rounded corners. If your app does one of the following, it cannot be rounded:įor example, an app might use per-pixel alpha layering to draw transparent pixels around its main window to achieve a custom shadow effect, which makes the window no longer a rectangle and therefore the system cannot round it. These apps have no frame or borders, and typically have heavily customized UI. Note, however, that the API is a hint to the system and does not guarantee rounding, depending on the customizations.Īpps that cannot ever be rounded, even if they call the opt-in API. If you address these issues in your app or call the opt-in API, described in the following section, then it's possible for the system to round your app's window.

Although we did try to round as many apps as possible with our system heuristics, there are some combinations of customizations that we can't predict so we provided a manual opt-in API for those cases.

Other customizations, such as extra non-child windows used for custom shadowsĬhanging one of these things will break automatic rounding.If your app is not rounded by policy, it could be caused by one of the following things:

It also includes apps that provide enough information to the system so it can properly round them, such as setting the WS_THICKFRAME and WS_CAPTION window styles or providing a 1-pixel non-client area border that the system can use to round the corners.Īpps that are not rounded by policy, but can be rounded.Īpps in this category generally want to customize the majority of the window frame but still want the system-drawn border and shadow, such as Microsoft Office. This includes apps that want a complete system-provided frame and caption-controls (min/max/close buttons), like Notepad. Apps fall into three main categories from the perspective of the Desktop Window Manager (DWM): If your app's main window doesn't receive automatic rounding, it's because you've customized your frame in a way that prevents it. Every day, Creatnx asks exactly one mirror “Am I beautiful?”.By design, apps are not rounded when maximized, snapped, running in a Virtual Machine (VM), running on a Windows Virtual Desktop (WVD), or running as a Windows Defender Application Guard (WDAG) window. \quad Creatnx has n mirrors, numbered from 1 1 1 to n n n.
