SGL - win32 made simple!

[henrin]

I have read many posts looking for easy win32 gui programming.
Not founding a good solution, and considering Win32 is almost
fantastic, I decided to fill the gap.

Here is SGL - Features:
- easy Win32 programming (better OOP)
- grid layout with alignmment and padding
- scalable GUI

The kit contains:
- help file (sgl.chm)
- dev kit: x.lib and x.h
- sample programs (source, project and exe files)

The available objects are:
- buttons
- table (data grid)
- image
- edit
- graph
- popups

The mandatoty Hello progam is just 12 lines:

    #include "sgl.h"
    int WINAPI WinMain (HINSTANCE hInst, HINSTANCE hPInst, PSTR cmdLine, int cmdShow)
    {
       SGL_Init(hInst, NULL) ;
       HWND panel = SGL_New(0, SGL_PANEL, 0, "SGL", -1, -1) ;
       HWND btn   = SGL_New(panel, SGL_CTRL_BUTTON, 0, "Hello!", 0, 0) ;
       SGL_Layout(panel) ;
       SGL_VisibleSet(panel, 1) ;
       SGL_Run() ;
       SGL_Exit() ;
       return 0 ;
    }

More samples in the downloadable kit.

Compliments, it works like a charm, in just 40 lines!

Although I've personally settled in GTK+ when it comes to GUI programming with C, I want to congratulate you for this effort!

I went through SGL docs, though in a hurry. Was impressed and I believe SGL deserves to go open-source, ideally in its own git repo. If not, it may be a good idea to also provide ming32 and/or mingw-w64 pre-compiled binaries.

Thanks for sharing and once again congrats for the effort so far.

Thank you jj2007 and migf1.
The story continues: here is the v1.1 version.

Some improvements in resizing and default values:

• Panel sizing is now possible.
• SGL fonts are now strictly linked to the desktop menu font.
• The separator object is now spanned to its parent border.

New features:

• New macros for testing the mouse buttons.
• New tool for Automatic resizing.
• New object OpenGL

To remain in upload size limit, only the 32-bit sample executables are included.
You still have:

• the help file
• the .h and the .lib (32 & 64-bit) files
• the samples: source, project files, .exe files

Next step : make it open source.

i've been using it for some tests.
thanks for the hard work!

A new release and the source code

The 1.2 release mainly adds a date-time popup. Two sample are provided:
- 2 date buttons for a round trip ticket,
- editing a date in a table (data grid).
One feature has been lost: the backgroung color for user editing is white and cannot be changed.

I have changed publishing:
- the development kit (*.h, *.lib and *.chm) and the samples are now there http://perso.numericable.fr/hserindat/sgl/,
- the source code can now be downloaded here (also includes the samples).

Terms of use:
SGL is freeware for any use: personal, commercial, etc. No registration is required to download it, and you can use it anonymously.
SGL can be freely distributed, but it can not be sold.
SGL is provided 'as-is', without any expressed or implied warranty. In no event will the author be held liable for any damages arising from the use of this software.

SGL 1.3 is here with new features:

- Temporary font loading.
- New tools for reading and writing in a configuration file.

other improvements and a new sample (custom message box).

The development kit (*.h, *.lib and *.chm) and the samples are here http://perso.numericable.fr/hserindat/sgl/v_1.3/release_sgldevkit.7z,
The source code can now be downloaded here (also includes the samples).

A light update.

SGL provided native scrolling under foreground windows [MouseWheelRouting].
As well as Windows10 now. This required some adjustment which accidentally broke the compatibility with Windows XP.
That is repaired with the 1.3.1 version.

The previous release was not exciting; the goodies were not emphazed enough.
Here is a nice one: a message box, in less than 200 lines (exe and ini files attached).

• Window size and position setting and saving for panels and buttons.
  
• Setting and saving of custom colors. 
• Custom popup. 
• Automatic size adjustments. 
• Version info (right click on the .exe file: properties / details).
• Native scrolling under foreground window as mentionned above.

The development kit (*.h, *.lib and *.chm) and the samples are here http://perso.numericable.fr/hserindat/sgl/v_1.3.1/release_sgldevkit.7z,
The source code can be downloaded here (attached file which also includes the source code of the samples).

Very nice! I had a look at the animated GIF example. How are you doing that?
These seem to be the relevant functions, but what do they use under the hood? Just curious...

SGL_ImagePlay(image, 100);
SGL_ImageFrameIndexSet(image, i);

[henrin]

Animated works for GIF, and for multiframe TIFF also! (win7 and above).

The relevant SGL functions are described in the help file : CONTROL OBJECTS / IMAGE (inside http://perso.numericable.fr/hserindat/sgl/v_1.3.1/release_sgldevkit.7z).

Under the hood, there is GDI+ and an animation thread. Unfortunately, at the time of development I did not find a very good gdi+ header. The header I have found in T-Clock (by Frankie) seems much cleaner.

The code for the image object is :
- sgl_gdiplus_.h  (GDI+ header)
- sgl_image_.h  (private header)
- sgl_image.c  (code)
- sgl_image.h  (public header)
and is attached to this post.

I tried to find animated TIFF images for testing but no luck so far I found only two here.

Under the hood, there is GDI+

In the meantime, I rolled my own, see here. But thanks for inspiring me

Good job henrin

henrin,
did you have any luck with animated PNGs? Firefox (and others, I suppose) "plays" them just fine, but GdipImageGetFrameCount returns always one frame
