QT平臺(tái)上模擬鼠標(biāo)事件案例是本文要介紹的內(nèi)容，主要是來(lái)了解QT平臺(tái)上的模擬鼠標(biāo)事件的應(yīng)用，具體內(nèi)容的實(shí)現(xiàn)來(lái)看本文詳解。需要導(dǎo)入QTest4.lib 否則會(huì)有連接時(shí)錯(cuò)誤

#include<QtTest/QTest> 
QTest::mouseClick(ui.mainPlayer,Qt::LeftButton,0,pos(),-1); 

QT平臺(tái)模擬鼠標(biāo)按鍵

和模擬鍵盤按鍵類似，也是通過(guò)發(fā)送相應(yīng)的事件來(lái)實(shí)現(xiàn)的，安裝相應(yīng)的事件監(jiān)聽器，具體發(fā)送事件：

QPoint pos;  
pos.setX(88);  
pos.setY(58);  
QMouseEvent *mEvnPress;  
QMouseEvent *mEvnRelease;  
mEvnPress = new QMouseEvent(QEvent::MouseButtonPress, pos, Qt::LeftButton,Qt::LeftButton, Qt::NoModifier);  
QApplication::sendEvent(QWidget::focusWidget(),mEvnPress);  
mEvnRelease = new QMouseEvent(QEvent::MouseButtonRelease, pos, Qt::LeftButton,Qt::LeftButton, Qt::NoModifier);  
QApplication::sendEvent(QWidget::focusWidget(),mEvnRelease);       

主要的分析函數(shù)是：    

QMouseEvent::QMouseEvent ( Type type, const QPoint & position,Qt::MouseButton button, Qt::MouseButtons buttons, Qt::KeyboardModifiersmodifiers ) 

參數(shù)分析：

The type parameter must be one of QEvent::MouseButtonPress,QEvent::MouseButtonRelease, QEvent::MouseButtonDblClick, or QEvent::MouseMove.  
The position is the mouse cursor's position relative to the receiving widget.   
The button that caused the event is given as a value from the Qt::MouseButtonenum.   
      If the event type is MouseMove, the appropriate button for this event isQt::NoButton.   
The mouse and keyboard states at the time of the event are specified by buttonsand modifiers.  
The globalPos() is initialized to QCursor::pos(), which may not be appropriate.Use the other constructor to specify the global position explicitly. 

主要說(shuō)明：

這里的pos的位置是接受鼠標(biāo)事件的widget的內(nèi)部的一個(gè)局部位置。也就是說(shuō)他的鼠標(biāo)按鍵的產(chǎn)生點(diǎn)是：先通過(guò)QApplication::sendEvent(QWidget::focusWidget(),mEvnPress);//也就是說(shuō)先是指明了傳遞給哪個(gè)widget，然后再根據(jù)mEventPress來(lái)進(jìn)行具體的再改widget中的定位，以及具體的按鍵是什么。
