Package com.formdev.flatlaf.ui

Class FlatWindowsNativeWindowBorder

java.lang.Object

com.formdev.flatlaf.ui.FlatWindowsNativeWindowBorder

All Implemented Interfaces:

FlatNativeWindowBorder.Provider

class FlatWindowsNativeWindowBorder
extends java.lang.Object
implements FlatNativeWindowBorder.Provider

Native window border support for Windows 10 when using custom decorations.

If the application wants to use custom decorations, the Windows 10 title bar is hidden (including minimize, maximize and close buttons), but not the resize borders (including drop shadow). Windows 10 window snapping functionality will remain unaffected: https://support.microsoft.com/en-us/windows/snap-your-windows-885a9b1e-a983-a3b1-16cd-c531795e6241
