SDL and MSEgui.

[fredvs]

Hello.

https://en.wikipedia.org/wiki/Simple_DirectMedia_Layer

There is a gem in MSEuniverse:
https://github.com/mse-org/mseuniverse/tree/main/sdl4msegui

The readme.txt:

---

Main concept of porting MSEgui to Windows, Linux, Mac OS, Android and iOS :

• Use SDL 2 for windowing, input event, thread management, networking, audio, and I/O management for all OS
• Use OpenGL context only for drawing from SDL2.0 (http://wiki.libsdl.org/moin.cgi/CategoryVideo)
• 2 options for 2D drawing engine, use cairo or mseopenglgdi.pas
• Use cairo for drawing engine, put pixels from cairo surface to opengl texture.

The project dates from 2012 and was not yet tested for Linux.

Here is the updated sdl4msegui testsdl for Linux:
[EDIT] Updated demo with image:
testsdl.zip

In Project_Options, Make tab, adapt the directories to target the patched source of mseide-msegui/lib

Here the patched version of mseide-msegui/lib for Linux:
[EDIT] Updated some SDL methods missing and fixed crash when closing the app.
lib_sdl_180524_2.zip

Note that this is absolutely not yet finished, but yes, some things are working yet.

Have lot of fun!
