## 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 sample.

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.

Example of use

        wxDebugReport report;
        wxDebugReportPreviewStd preview;

        report.AddCurrentContext();  // could also use AddAll()
        report.AddCurrentDump();     // to do both at once

        if ( preview.Show(report) )
            report.Process();

Data structures

This enum is used for functions that report either the current state or the state during the last (fatal) exception:

    enum wxDebugReport::Context
    {
        Context_Current,
        Context_Exception
    };

### wxDebugReport::wxDebugReport

wxDebugReport()

The constructor creates a temporary directory where the files that will be included in the report are created. Use IsOk() to check for errors.

### wxDebugReport::~wxDebugReport

~wxDebugReport()

The destructor normally destroys the temporary directory created in the constructor with all the files it contains. Call Reset() to prevent this from happening.

### wxDebugReport::AddAll

void AddAll(Context context = Context_Exception)

Adds all available information to the report. Currently this includes a text (XML) file describing the process context and, under Win32, a minidump file.

### wxDebugReport::AddContext

bool AddContext(Context ctx)

Add an XML file containing the current or exception context and the stack trace.

### wxDebugReport::AddCurrentContext

bool AddCurrentContext()

The same as AddContext(Context_Current).

### wxDebugReport::AddCurrentDump

bool AddCurrentDump()

The same as AddDump(Context_Current).

### wxDebugReport::AddDump

bool AddDump(Context ctx)

Adds the minidump file to the debug report.

Minidumps are only available under recent Win32 versions (`dbghlp32.dll` can be installed under older systems to make minidumps available).

### wxDebugReport::AddExceptionContext

bool AddExceptionContext()

The same as AddContext(Context_Exception).

### wxDebugReport::AddExceptionDump

bool AddExceptionDump()

The same as AddDump(Context_Exception).

### wxDebugReport::AddFile

void AddFile(const wxString& filename, const wxString& description)

Add another file to the report. If filename is an absolute path, it is copied to a file in the debug report directory with the same name. Otherwise the file should already exist in this directory

description only exists to be displayed to the user in the report summary shown by wxDebugReportPreview.

AddText()

### wxDebugReport::AddText

bool AddText(const wxString& filename, const wxString& text, const wxString& description)

This is a convenient wrapper around AddFile. It creates the file with the given name and writes text to it, then adds the file to the report. The filename shouldn't contain the path.

Returns `true` if file could be added successfully, `false` if an IO error occurred.

### wxDebugReport::DoAddCustomContext

void DoAddCustomContext(wxXmlNode * nodeRoot)

This function may be overridden to add arbitrary custom context to the XML context file created by AddContext. By default, it does nothing.

### wxDebugReport::DoAddExceptionInfo

bool DoAddExceptionInfo(wxXmlNode* nodeContext)

This function may be overridden to modify the contents of the exception tag in the XML context file.

### wxDebugReport::DoAddLoadedModules

bool DoAddLoadedModules(wxXmlNode* nodeModules)

This function may be overridden to modify the contents of the modules tag in the XML context file.

### wxDebugReport::DoAddSystemInfo

bool DoAddSystemInfo(wxXmlNode* nodeSystemInfo)

This function may be overridden to modify the contents of the system tag in the XML context file.

### wxDebugReport::GetDirectory

const wxString& GetDirectory() const

Returns the name of the temporary directory used for the files in this report.

This method should be used to construct the full name of the files which you wish to add to the report using AddFile.

### wxDebugReport::GetFile

bool GetFile(size_t n, wxString* name, wxString* desc) const

Retrieves the name (relative to GetDirectory()) and the description of the file with the given index. If n is greater than or equal to the number of filse, `false` is returned.

### wxDebugReport::GetFilesCount

size_t GetFilesCount() const

Gets the current number files in this report.

### wxDebugReport::GetReportName

wxString GetReportName() const

Gets the name used as a base name for various files, by default wxApp::GetAppName() is used.

### wxDebugReport::IsOk

bool IsOk() const

Returns `true` if the object was successfully initialized. If this method returns `false` the report can't be used.

### wxDebugReport::Process

bool Process()

Processes this report: the base class simply notifies the user that the report has been generated. This is usually not enough -- instead you should override this method to do something more useful to you.

### wxDebugReport::RemoveFile

void RemoveFile(const wxString& name)

Removes the file from report: this is used by wxDebugReportPreview to allow the user to remove files potentially containing private information from the report.

### wxDebugReport::Reset

void Reset()

Resets the directory name we use. The object can't be used any more after this as it becomes uninitialized and invalid.
