点击面板按键无作用

1，在Activity的onStop（）函数中隐藏Widget。

int HomeLauncher::onStop()
{
QWidget* pObj = mProperty->getUiObj();
if(pObj)
{
 pObj->hide();
 }
return 0;
}

 

2，在Activity的onDestory中释放掉了改Widget

int HomeLauncher::onDestory()
{
    QWidget* pObj = mProperty->getUiObj();
    if(pObj)
    {
        pObj->deleteLater();
        pObj = NULL;
    }
    return 0;
}
