Although not mandatory, using this class is strongly recommended as data included in the debug report might contain sensitive private information and the user should be notified about it as well as having a possibility to examine the data which had been gathered to check whether this is effectively the case and discard the debug report if it is. wxDebugReportPreview is an abstract base class, currently the only concrete class deriving from it is wxDebugReportPreviewStd. @library{wxqa} @category{debugging} */ class wxDebugReportPreview { public: /** Default constructor. */ wxDebugReportPreview(); /** Destructor is trivial as well but should be virtual for a base class. */ virtual ~wxDebugReportPreview(); /** Present the report to the user and allow him to modify it by removing some or all of the files and, potentially, adding some notes. @return @true if the report should be processed or @false if the user chose to cancel report generation or removed all files from it. */ virtual bool Show(wxDebugReport& dbgrpt) const = 0; }; /** @class wxDebugReportCompress wxDebugReportCompress is a wxDebugReport which compresses all the files in this debug report into a single ZIP file in its wxDebugReport::Process() function. @library{wxqa} @category{debugging} */ class wxDebugReportCompress : public wxDebugReport { public: /** Default constructor does nothing special. */ wxDebugReportCompress(); /** Returns the full path of the compressed file (empty if creation failed). */ const wxString& GetCompressedFileName() const; }; /** @class wxDebugReport wxDebugReport is used to generate a debug report, containing information about the program current state. It is usually used from wxApp::OnFatalException() as shown in the @ref page_samples_debugrpt. A wxDebugReport object contains one or more files. A few of them can be created by the class itself but more can be created from the outside and then added to the report. Also note that several virtual functions may be overridden to further customize the class behaviour. Once a report is fully assembled, it can simply be left in the temporary directory so that the user can email it to the developers (in which case you should still use wxDebugReportCompress to compress it in a single file) or uploaded to a Web server using wxDebugReportUpload (setting up the Web server to accept uploads is your responsibility, of course). Other handlers, for example for automatically emailing the report, can be defined as well but are not currently included in wxWidgets. A typical usage example: @code wxDebugReport report; wxDebugReportPreviewStd preview; report.AddCurrentContext(); // could also use AddAll() report.AddCurrentDump(); // to do both at once if ( preview.Show(report) ) report.Process(); @endcode @library{wxqa} @category{debugging} */ class wxDebugReport { public: /** This enum is used for functions that report either the current state or the state during the last (fatal) exception. */ enum Context { Context_Current, Context_Exception }; /** The constructor creates a temporary directory where the files that will be included in the report are created.
