Re: [MSEide-MSEgui-talk] Can MSEide be built for ARM 11 - Raspberry Pi ?
Open GL is not well suited as backend for 2D GUI IMHO. = Raspberry PI uses OpenGL ES for 3D, OpenVG for 2D & OpenMAX for media. (http://en.wikipedia.org/wiki/Raspberry_Pi). Win7 & Win8 use DirectX for GUI draing and succeed (although DirectX is both 2D[DirectDraw] & 3D[Direct3D]). Possibly the 3D OpenGL solution should be accompanied by a 2D one.

Also "Raspberry PI" allows to install full FPC+MSEide+MSEgui build environment - native or QEMUlated. MSEgui is very fast on xlib-Xorg === FreePascal people can't get why LAZARUS is so slow on this soap-case "machine". -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.

MSEgui has more possibilities for optimisation because the "widgetset" is embedded and under full control. It is a tremendous task to make a Lazarus-like system basically working and to adapt and optimise it continuousely to the ever changing widgetsets. For MSEgui this is much easier to achieve. Additionally MSEgui is mostly a single person undertaking which has its advantages and I deliberately work with old and slow computers. ;-) Although I don't know if Raspberry Pi performance is sufficient for the full MSEgui development environment.

Lazarus has an additional complicated layer between widgetset and and application. MSEgui has more possibilities for optimisation because the "widgetset" is embedded and under full control. === And may be becfuse of the design "window per form" as contrarry to "window per widget primitive". -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
