wxEventLoopActivator Class Reference

#include <wx/evtloop.h>

Detailed Description

Makes an event loop temporarily active.

You normally don't need to use this class before calling wxEventLoopBase::Run(), as Run() already uses it. Use this class only when an event loop must be temporarily active without entering Run(), or from a custom Run() implementation which doesn't call the base class version.

This class is used to make the event loop active during its life-time, e.g.:

class MyEventLoop : public wxEventLoopBase { ... };
 
void RunMyLoop()
{
    MyEventLoop loop;
    wxEventLoopActivator activate(&loop);
 
    ...
} // the previously active event loop restored here

Constructor & Destructor Documentation

wxEventLoopActivator()

wxEventLoopActivator::wxEventLoopActivator

(

wxEventLoopBase *

loop

)

Makes the loop passed as the parameter currently active.

This saves the current return value of wxEventLoopBase::GetActive() and then calls wxEventLoopBase::SetActive() with the given loop.

~wxEventLoopActivator()

wxEventLoopActivator::~wxEventLoopActivator

(

)

Restores the previously active event loop stored by the constructor.
