| int wxDebugContext::Check | ( | ) |
Checks the memory blocks for errors, starting from the currently set checkpoint.
| bool wxDebugContext::Dump | ( | ) |
Performs a memory dump from the currently set checkpoint, writing to the current debug stream. Calls the Dump member function for each wxObject derived instance.
| bool wxDebugContext::GetCheckPrevious | ( | ) |
Returns true if the memory allocator checks all previous memory blocks for errors. By default, this is false since it slows down execution considerably.
| bool wxDebugContext::GetDebugMode | ( | ) |
Returns true if debug mode is on. If debug mode is on, the wxObject new and delete operators store or use information about memory allocation. Otherwise, a straight malloc and free will be performed by these operators.
| int wxDebugContext::GetLevel | ( | ) |
Gets the debug level (default 1). The debug level is used by the wxTraceLevel function and the WXTRACELEVEL macro to specify how detailed the trace information is; setting a different level will only have an effect if trace statements in the application specify a value other than one. This is obsolete, replaced by wxLog functionality.
| ostream wxDebugContext::GetStream | ( | ) |
Returns the output stream associated with the debug context. This is obsolete, replaced by wxLog functionality.
| streambuf* wxDebugContext::GetStreamBuf | ( | ) |
Returns a pointer to the output stream buffer associated with the debug context. There may not necessarily be a stream buffer if the stream has been set by the user. This is obsolete, replaced by wxLog functionality.
| bool wxDebugContext::HasStream | ( | ) |
Returns true if there is a stream currently associated with the debug context. This is obsolete, replaced by wxLog functionality.
| bool wxDebugContext::PrintClasses | ( | ) |
Prints a list of the classes declared in this application, giving derivation and whether instances of this class can be dynamically created.
| bool wxDebugContext::PrintStatistics | ( | bool | detailed = true |
) |
Performs a statistics analysis from the currently set checkpoint, writing to the current debug stream. The number of object and non-object allocations is printed, together with the total size.
| detailed | If true, the function will also print how many objects of each class have been allocated, and the space taken by these class instances. |
| void wxDebugContext::SetCheckPrevious | ( | bool | check | ) |
Tells the memory allocator to check all previous memory blocks for errors. By default, this is false since it slows down execution considerably.
| void wxDebugContext::SetCheckpoint | ( | bool | all = false |
) |
Sets the current checkpoint: Dump and PrintStatistics operations will be performed from this point on. This allows you to ignore allocations that have been performed up to this point.
| all | If true, the checkpoint is reset to include all memory allocations since the program started. |
| void wxDebugContext::SetDebugMode | ( | bool | debug | ) |
Sets the debug mode on or off. If debug mode is on, the wxObject new and delete operators store or use information about memory allocation. Otherwise, a straight malloc and free will be performed by these operators. By default, debug mode is on if __WXDEBUG__ is defined. If the application uses this function, it should make sure that all object memory allocated is deallocated with the same value of debug mode. Otherwise, the delete operator might try to look for memory information that does not exist.
| bool wxDebugContext::SetFile | ( | const wxString & | filename | ) |
Sets the current debug file and creates a stream. This will delete any existing stream and stream buffer. By default, the debug context stream outputs to the debugger (Windows) or standard error (other platforms).
| void wxDebugContext::SetLevel | ( | int | level | ) |
Sets the debug level (default 1). The debug level is used by the wxTraceLevel function and the WXTRACELEVEL macro to specify how detailed the trace information is; setting a different level will only have an effect if trace statements in the application specify a value other than one. This is obsolete, replaced by wxLog functionality.
| void wxDebugContext::SetShutdownNotifyFunction | ( | wxShutdownNotifyFunction | func | ) |
Installs a function to be called at the end of wxWidgets shutdown. It will be called after all files with global instances of wxDebugContextDumpDelayCounter have run their destructors. The shutdown function must be take no parameters and return nothing.
| bool wxDebugContext::SetStandardError | ( | ) |
Sets the debugging stream to be the debugger (Windows) or standard error (other platforms). This is the default setting. The existing stream will be flushed and deleted. This is obsolete, replaced by wxLog functionality.
| void wxDebugContext::SetStream | ( | ostream * | stream, | |
| streambuf * | streamBuf = NULL | |||
| ) |
Sets the stream and optionally, stream buffer associated with the debug context. This operation flushes and deletes the existing stream (and stream buffer if any). This is obsolete, replaced by wxLog functionality.
| stream | Stream to associate with the debug context. Do not set this to NULL. | |
| streamBuf | Stream buffer to associate with the debug context. |
