# wxBusyInfo Class Reference
[Common Dialogs]

`#include </home/work/projects/wx/2.9/wx/interface/wx/busyinfo.h>`

## Detailed Description

This class makes it easy to tell your user that the program is temporarily busy.

Just create a wxBusyInfo object on the stack, and within the current scope, a message window will be shown.

For example:

            wxBusyInfo wait("Please wait, working...");

            for (int i = 0; i < 100000; i++)
            {
                DoACalculation();
            }

It works by creating a window in the constructor, and deleting it in the destructor.

You may also want to call wxTheApp->Yield() to refresh the window periodically (in case it had been obscured by other windows, for example) like this:

            wxWindowDisabler disableAll;
            wxBusyInfo wait("Please wait, working...");

            for (int i = 0; i < 100000; i++)
            {
                DoACalculation();

                if ( !(i % 1000) )
                    wxTheApp->Yield();
            }

but take care to not cause undesirable reentrancies when doing it (see wxApp::Yield for more details). The simplest way to do it is to use wxWindowDisabler class as illustrated in the above example.

Note that a wxBusyInfo is always built with the `wxSTAY_ON_TOP` window style (see wxFrame window styles for more info).
