BGRAControls and MSEgui #86

Closed fredvs closed 4 years ago

fredvs commented 4 years ago

Hello.

I am trying to convert some BGRABitmap demos using MSEgui widgetset. Now I am busy with the "fractal_tree" demo.

But it fails to compile with that error:

bgravirtualscreen.pas(48,34) Fatal: Can't find unit LMessages used by BGRAVirtualScreen

Is it possible to use BGRAControls without the LCL LMessages unit (and all other LCL dependencies like graphtypes) ?

Thanks.

Re-hello.

I did not catch the advantage of bgravirtualscreen, is it possible to draw on a canvas of a maximized form without bgravirtualscreen, would it be slower or give some limitation?

Thanks for some light.

Re-re hello.

Ok, the convertion of "Fractal Tree" BGRABitmap demo using MSEgui widgetset is ok.

By the way, big WoW.

This without using bgravirtualscreen but directly on the canvas of a tmsepaintbox, so I dont know if it is the good way and if there will be problems.

It will be good without bgravirtualscreen. Looking good.

BGRAVirtualScreen can provide some optimizations but if it works well with a TMSEPaintBox, that's quite good. In particular if you refresh the whole area anyway.

Ha ok, thanks. By the way, I dont use a TMSEPaintBox anymore but directly the canvas of a TMSEform and the result is perfect. (And faster than the same demo done with a TLCLform, but, ok, ok, no propaganda.)
