As @b wxLogDebug, trace functions only do something in debug build and
expand to nothing in the release one. The reason for making
it a separate function from it is that usually there are a lot of trace
messages, so it might make sense to separate them from other debug messages.
The trace messages also usually can be separated into different categories and
the second and third versions of this function only log the message if the
@a mask which it has is currently enabled in wxLog. This
allows to selectively trace only some operations and not others by changing
the value of the trace mask (possible during the run-time).
For the second function (taking a string mask), the message is logged only if
the mask has been previously enabled by the call to
wxLog::AddTraceMask or by setting
@ref overview_envvars "@c WXTRACE environment variable".
The predefined string trace masks
used by wxWidgets are:
wxTRACE_MemAlloc: trace memory allocation (new/delete)
wxTRACE_Messages: trace window messages/X callbacks
wxTRACE_ResAlloc: trace GDI resource allocation
wxTRACE_RefCount: trace various ref counting operations
wxTRACE_OleCalls: trace OLE method calls (Win32 only)
@b Caveats: since both the mask and the format string are strings,
this might lead to function signature confusion in some cases:
if you intend to call the format string only version of wxLogTrace,
then add a %s format string parameter and then supply a second string parameter
for that %s, the string mask version of wxLogTrace will erroneously get called instead, since you are supplying two string parameters to the function.
In this case you'll unfortunately have to avoid having two leading
string parameters, e.g. by adding a bogus integer (with its %d format string).
The third version of the function only logs the message if all the bits
corresponding to the @a mask are set in the wxLog trace mask which can be
set by wxLog::SetTraceMask. This version is less
flexible than the previous one because it doesn't allow defining the user
trace masks easily - this is why it is deprecated in favour of using string
trace masks.
wxTraceMemAlloc: trace memory allocation (new/delete)
wxTraceMessages: trace window messages/X callbacks
wxTraceResAlloc: trace GDI resource allocation
