Technical Field
The invention relates to the field of Flash playing, in particular to a host container and a method for playing Flash in WPF.
Background
WPF (Windows Presentation Foundation ) is a Microsoft new generation graphic system, operates under NET Framework 3.0 architecture, and provides a unified description and operation method for user interfaces, 2D/3D graphics, documents and media. WPF based on DirectX technology not only brings unprecedented 3D interface, but also its graphics vector rendering engine greatly improves traditional 2D interface. DirectX: direct extenssion, DX, is a multimedia programming interface created by microsoft corporation.
The playing of Flash animation is widely adopted by an official GDI + (Graphics device interface) -based player. When WPF based on DirectX bears Flash based on GDI +, the graphical interface elements rendered based on DirectX and the graphical interface elements rendered based on GDI + are displayed in a same window in a laminated mode. Two rendering technologies are adopted in the same visual area, and a space domain (airspace) problem is generated, namely, layout limitation caused by playing Flash in WPF: the Flash player window (i.e., the Win32 window) covers the WPF window. The support of the WPF on Flash playing is not friendly, only a Win32 component based on GDI + is provided, the WPF is realized through the load bearing of a WPF control host container (Windows FormsHost), a window body is always displayed above a WPF window body during playing and is displayed at the top, and other controls are covered.
