Problema com Funçao que Captura o evento de click do Mouse do Sistema Operacional

Rodrigocg

A funcao esta funcionando perfeitamente, o problema é quando eu do um Click seguro e arrasto o cursor... ele identifica milhoes de click e eu quero que identifique uma vez só.

seghe o codigo:

@#include <QtCore/QCoreApplication>
#include <QDebug>
#include <Windows.h>

HHOOK MouseHook= NULL;

using namespace std;

LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
int LBUTTON=0, RBUTTON=0;
if (nCode < 0) // do not process the message
return CallNextHookEx(0, nCode,wParam, lParam);

LBUTTON=(int)GetKeyState(VK_LBUTTON);
RBUTTON=(int)GetKeyState(VK_RBUTTON);

if(LBUTTON<0||RBUTTON<0)
    qDebug()<<"CLICK";

return CallNextHookEx(0, nCode, wParam,lParam);

}

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
MouseHook = SetWindowsHookEx(WH_MOUSE_LL, MouseProc, NULL, 0);
if(MouseHook == NULL)
{
qDebug() << "Hook failed";
}
return a.exec();
}

Alguem arrisca uma soluçao?

Resolvi o problema da seguinte maneira:
@#include <QtCore/QCoreApplication>
#include <QDebug>
#include <Windows.h>

HHOOK MouseHook= NULL;
int flagLBUTTON=0,flagRBUTTON=0;

using namespace std;

LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
int LBUTTON=0, RBUTTON=0;
if (nCode < 0) // do not process the message
return CallNextHookEx(0, nCode,wParam, lParam);

LBUTTON=(int)GetKeyState(VK_LBUTTON);
RBUTTON=(int)GetKeyState(VK_RBUTTON);

if(LBUTTON<0)
    flagLBUTTON=1;
else if(LBUTTON>=0&&flagLBUTTON==1) flagLBUTTON=-1;

if(RBUTTON<0)
    flagRBUTTON=1;
else if(RBUTTON>=0&&flagRBUTTON==1) flagRBUTTON=-1;


if(flagLBUTTON!=0&&flagLBUTTON==-1)
{
    qDebug()<<"LBUTTON";
    flagLBUTTON=0;
}
if(flagRBUTTON!=0&&flagRBUTTON==-1)
{
    qDebug()<<"RBUTTON";
    flagRBUTTON=0;
}

return CallNextHookEx(0, nCode, wParam,lParam);

}

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
MouseHook = SetWindowsHookEx(WH_MOUSE_LL, MouseProc, NULL, 0);
if(MouseHook == NULL)
{
qDebug() << "Hook failed";
}
return a.exec();
}

alguem conhece alguma soluçao que nao utilize essa gambiarra?

Achei uma soluçao melhor...

segue:

@#include <QtCore/QCoreApplication>
#include <QDebug>
#include <Windows.h>

HHOOK MouseHook= NULL;

using namespace std;

LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
int LBUTTON,RBUTTON;
if (nCode < 0) // do not process the message
return CallNextHookEx(0, nCode,wParam, lParam);

LBUTTON = GetAsyncKeyState(VK_LBUTTON);
if(LBUTTON==-32767)
    qDebug()<<"Click1";

RBUTTON = GetAsyncKeyState(VK_RBUTTON);
if(RBUTTON==-32767)
    qDebug()<<"Click2";

return CallNextHookEx(0, nCode, wParam,lParam);

}

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
MouseHook = SetWindowsHookEx(WH_MOUSE_LL, MouseProc, NULL, 0);
if(MouseHook == NULL)
{
qDebug() << "Hook failed";
}
return a.exec();
