wxBusyInfo Class Reference

#include </home/zeitlin/src/wx/github/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.

以下に例を示します:

        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).
