wxWidgets一些代码片段(不断更新中)

1:获得本程序的进程ID

         long gpid;
        gpid=::wxGetProcessId();
        wxString tempWxString;
        tempWxString.sprintf(wxT( "%d"), gpid);
        wxMessageBox(tempWxString, _( "Welcome to..."));

 

2:定时器

        ::wxStartTimer();
         long gt;
        gt=::wxGetElapsedTime( true);
        wxString tempWxString;
        tempWxString.sprintf(wxT( "is %d second"), gt/1000);
        wxMessageBox(tempWxString, _( "Welcome to..."));

 

3:一句话COPY文件

//bool wxCopyFile(const wxString& file1, const wxString& file2, bool overwrite = true)

::wxCopyFile( "c:\\README.TXT", "d:\\1.txt", true);

 

4:获得系统文件夹

        wxString osDirectory;
        osDirectory=::wxGetOSDirectory();
        wxMessageBox(osDirectory, _( "Welcome to..."));

 

5:获得系统版本信息

        wxString OsVersion;
        OsVersion=::wxGetOsDescription();
        wxMessageBox(OsVersion, _( "axi Test"));

 

6：窗体坐标

        wxPoint wp;
        wp=frame->GetClientAreaOrigin();
         int x1,y1;
        x1=wp.x;
        y1=wp.y;
        wxString tempWxString;
        tempWxString.sprintf(wxT( "x: %d y: %d"), x1,y1);
        wxMessageBox(tempWxString, _( "frame xy"));

 

其他的一些文件操作

::wxRemoveFile
bool wxRemoveFile( const wxString& file)

Removes file, returning true if successful.





::wxRenameFile
bool wxRenameFile( const wxString& file1, const wxString& file2, bool overwrite = true)

Renames file1 to file2, returning true if successful.

If overwrite parameter is true ( default), the destination file is overwritten if it exists, but if overwrite is false, the functions fails in this case.

::wxRmdir
bool wxRmdir( const wxString& dir, int flags=0)

Removes the directory dir, returning true if successful. Does not work under VMS.

The flags parameter is reserved for future use.

Please notice that there is also a wxRmDir() function which simply wraps the standard POSIX rmdir() function and so return an integer error code instead of a boolean value (but otherwise is currently identical to wxRmdir), don't confuse these two functions.
