If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.

You can either use the precompiled libraries from <A HREF="http://www.libsdl.org/download.php"> the SDL Download web site </A>, or you can build SDL yourself.
|

</p>

Building SDL
|
|
</H3>
|
|
<P>
|
|
Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. <CODE>SDL_VS2008.sln</CODE> This should open up the IDE.
|
|
</P>
|
|
<P>
|
|
There are different solution files for the various
|
|
versions of the IDE. Please use the appropiate version
|
|
2008, 2010 or 2012; the 2010EE and 2012EE files
|
|
should be used with the "Express Edition" releases.
|
|
</P>
|
|
<P>
|
|
Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
|
|
</P>
|
|
<P>
|
|
This is done by right clicking on each project in turn (Projects are listed in
|
|
the Workspace panel in the FileView tab), and selecting "Build".
|
|
</P>
|
|
<P>
|
|
You may get a few warnings, but you should not get any errors. You do have to
|
|
have at least the DirectX 9 SDK installed, however. The latest
|
|
version of DirectX can be downloaded from <A HREF="http://www.microsoft.com">Microsoft</A>.
|
|
</P>
|
|
<P>
|
|
Later, we will refer to the following .lib and .dll files that have just been
|
|
generated:
|
|
</P>
|
|
<ul>
|
|
<li> SDL2.dll</li>
|
|
<li> SDL2.lib</li>
|
|
<li> SDL2main.lib</li>
|
|
</ul>
|
|
<P>
|
|
Search for these using the Windows Find (Windows-F) utility inside the VisualC directory.
|
|
</P>

Creating a Project with SDL
|
|
</H3>
|
|
<P>
|
|
Create a project as a Win32 Application.
|
|
</P>
|
|
<P>
|
|
Create a C++ file for your project.
|
|
</P>
|
|
<P>
|
|
Set the C runtime to "Multi-threaded DLL" in the menu: <CODE>Project|Settings|C/C++
|
|
tab|Code Generation|Runtime Library </CODE>.
|
|
</P>
|
|
<P>
|
|
Add the SDL <CODE>include</CODE> directory to your list of includes in the
|
|
menu: <CODE>Project|Settings|C/C++ tab|Preprocessor|Additional include directories </CODE>
|
|
.
|
|
<br>
|
|
<STRONG><FONT color="#009900">VC7 Specific: Instead of doing this I find it easier to
|
|
add the include and library directories to the list that VC7 keeps. Do this by
|
|
selecting Tools|Options|Projects|VC++ Directories and under the "Show
|
|
Directories For:" dropbox select "Include Files", and click the "New Directory
|
|
Icon" and add the [SDLROOT]\include directory (e.g. If you installed to
|
|
c:\SDL\ add c:\SDL\include). Proceed to change the
|
|
dropbox selection to "Library Files" and add [SDLROOT]\lib.</FONT></STRONG>
|
|
</P>
|
|
<P>
|
|
The "include directory" I am referring to is the <CODE>include</CODE> folder
|
|
within the main SDL directory (the one that this HTML file located within).
|
|
</P>
|
|
<P>
|
|
Now we're going to use the files that we had created earlier in the Build SDL
|
|
step.
|
|
</P>
|
|
<P>
|
|
Copy the following files into your Project directory:
|
|
</P>
|
|
<ul>
|
|
<li> SDL2.dll</li>
|
|
</ul>
|
|
<P>
|
|
Add the following files to your project (It is not necessary to copy them to
|
|
your project directory):
|
|
</P>
|
|
<ul>
|
|
<li> SDL2.lib </li>
|
|
<li> SDL2main.lib</li>
|
|
</ul>
|
|
<P>
|
|
(To add them to your project, right click on your project, and select "Add
|
|
files to project")
|
|
</P>
|
|
<P><STRONG><FONT color="#009900">Instead of adding the files to your project it is more
|
|
desireable to add them to the linker options: Project|Properties|Linker|Command
|
|
Line and type the names of the libraries to link with in the "Additional
|
|
Options:" box. Note: This must be done for each build
|
|
configuration (e.g. Release,Debug).</FONT></STRONG></P>

SDL 101, First Day of Class
|
|
</H3>
|
|
<P>
|
|
Now create the basic body of your project. The body of your program should take
|
|
the following form: <CODE>
|
|
<PRE>
|
|
#include "SDL.h"
|
|
|
|
int main( int argc, char* argv[] )
|
|
{
|
|
// Body of the program goes here.
|
|
return 0;
|
|
}
|
|
</PRE>
|
|
</CODE>
|
|
<P></P>
|
|
<H3>
|
|
That's it!
|
|
</H3>
|
|
<P>
|
|
I hope that this document has helped you get through the most difficult part of
|
|
using the SDL: installing it. Suggestions for improvements to this document
|
|
should be sent to the writers of this document.
