.TH SDL_ShowSimpleMessageBox 3 "SDL 3.1.0" "SDL" "SDL3 FUNCTIONS"
.SH NAME
SDL_ShowSimpleMessageBox \- Display a simple modal message box\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3/SDL.h\(dq
.PP
.BI "int SDL_ShowSimpleMessageBox(Uint32 flags, const char *title, const char *message, SDL_Window *window);
.fi
.SH DESCRIPTION
If your needs aren't complex, this function is preferred over

.BR SDL_ShowMessageBox
\[char46]
.BR flags
may be any of the following:


\(bu 
.BR
.BR SDL_MESSAGEBOX_ERROR
: error dialog

\(bu 
.BR
.BR SDL_MESSAGEBOX_WARNING
: warning dialog

\(bu 
.BR
.BR SDL_MESSAGEBOX_INFORMATION
: informational
  dialog

This function should be called on the thread that created the parent
window, or on the main thread if the messagebox has no parent\[char46] It will
block execution of that thread until the user clicks a button or closes the
messagebox\[char46]

This function may be called at any time, even before

.BR SDL_Init
()\[char46] This makes it useful for reporting errors like a
failure to create a renderer or OpenGL context\[char46]

On X11, SDL rolls its own dialog box with X11 primitives instead of a
formal toolkit like GTK+ or Qt\[char46]

Note that if 
.BR SDL_Init
() would fail because there isn't any
available video target, this function is likely to fail for the same
reasons\[char46] If this is a concern, check the return value from this function
and fall back to writing to stderr if you can\[char46]

.SH FUNCTION PARAMETERS
.TP
.I flags
an 
.BR SDL_MessageBoxFlags
 value

.TP
.I message

.SH RETURN VALUE
