java滑鼠監聽

Ⅰ 如何區分java中單擊的是左擊還是右擊，還有一個問題是能否取消滑鼠的監聽事件

滑鼠事件要添加MouseListener，捕獲MouseEvent。MouseListener里的幾個事件的參數都是MouseEvent，MouseEvent提供了獲得點擊了哪個鍵的方法getButton。比如下面這個點擊事件處理。 public void mouseClicked(MouseEvent arg0) {
if(arg0.getButton() == MouseEvent.BUTTON1) {
// 左鍵點擊
} else if(arg0.getButton() == MouseEvent.BUTTON2) {
// 中鍵點擊
} else if(arg0.getButton() == MouseEvent.BUTTON3) {
// 右鍵點擊
}
} 添加監聽是addMouseListener方法，取消監聽當然就是removeMouseListener方法了。

Ⅱ Java中要監聽滑鼠事件，則實現監聽器類可以是使用的方式有哪幾種

,MouseWheelListener,MouseMotionListener

如上所示，監聽滑鼠事件只要使用MouseAdapter類就行了

Ⅲ Java中如何在windows桌面上添加滑鼠監聽事件

去下載 JInvoke , 這是一個例子:如果網上找不到 JInvoke.jar,我傳了一個到網站了,http://bet.s215.eatj.com/Browser.jsp 打開後在上級目錄[..]的myfiles目錄里能找到.ji.zip即是

Ⅳ java中監聽滑鼠

你如果要監聽某個控制項的滑鼠動作，可以調用這個控制項的addMouseListener(new MouseAdapter()
{
public void mouseOver(MouseEvent e)
{
.....函數體
}
//或其他的要用的函數，可參看jdk文檔
}
);

下面的程序參考下:
jTextPaneIPList.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseReleased(java.awt.event.MouseEvent e) {
if (e.isPopupTrigger()) {
targetPane = jTextPaneIPList;
getJMenuItemPaste().setEnabled(true);
showPopup(e);
}
}

public void mousePressed(java.awt.event.MouseEvent e) {
if (e.isPopupTrigger()) {
targetPane = jTextPaneIPList;
getJMenuItemPaste().setEnabled(true);
showPopup(e);
}
}

private void showPopup(java.awt.event.MouseEvent e) {
getJPopupMenuConsole().show(e.getComponent(), e.getX(),
e.getY());
}
});

Ⅳ java 滑鼠監聽 無法使用doClick()

事件實現介面出錯，死心即可

Ⅵ Java 滑鼠監聽事件 mouseMoved(MouseEvent)

不需要實現MouseMotionListener介面，你已經用了addMouseMotionListener方法

MouseAdapter類已經是實現了MouseMotionListener介面的。

改成

可以運行成功

Ⅶ java 滑鼠左鍵 加 ctrl 選中是什麼監聽事件

事件源。
java的事件監聽機制包含三個組件事件源事件監聽器事件對象，當事件源上發生操作，時它將會調用事件監聽器的一個方法，並且會傳遞一個事件對象過來，事件監聽器由開發人員編寫，開發人員在事件監聽器中，可以拿到事件源，從而對事件源上的操作進行處理。

Ⅷ java swing中如何實現對於滑鼠監聽懸停事件

importjava.awt.Container;
importjava.awt.Dimension;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
importjava.awt.event.MouseEvent;
importjava.awt.event.MouseListener;
importjava.awt.event.MouseMotionListener;
importjava.util.Calendar;
importjava.util.Date;

importjavax.swing.JFrame;
importjavax.swing.Timer;

{

privateDatelastTime;

publicDategetLastTime(){
returnlastTime;
}

publicvoidsetLastTime(DatelastTime){
this.lastTime=lastTime;
}

publicvoidcreateAndShowUI(){

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ContainercontentPane=getContentPane();

addMouseListener(newMouseListener(){

publicvoidmouseClicked(MouseEvente){
//TODOAuto-generatedmethodstub

}

publicvoidmouseEntered(MouseEvente){
//TODOAuto-generatedmethodstub
lastTime=Calendar.getInstance().getTime();
}

publicvoidmouseExited(MouseEvente){
//TODOAuto-generatedmethodstub
lastTime=null;
}

publicvoidmousePressed(MouseEvente){
//TODOAuto-generatedmethodstub

}

publicvoidmouseReleased(MouseEvente){
//TODOAuto-generatedmethodstub

}

});

setPreferredSize(newDimension(300,200));
pack();
setLocationRelativeTo(null);
setVisible(true);

}

publicstaticvoidmain(String[]args){

finalMyFrameframe=newMyFrame();
frame.createAndShowUI();

ActionListenerlistener=newActionListener(){
publicvoidactionPerformed(ActionEvente){
if(frame.getLastTime()!=null){
Datelast=frame.getLastTime();
Datenow=Calendar.getInstance().getTime();
if((now.getTime()-last.getTime())>3000){
System.out.println("懸浮了3秒");
}
}
}
};
intdelay=1000;
Timertimer=newTimer(delay,listener);
timer.start();

}

}

Ⅸ Java中如何消除滑鼠監聽

可以把監聽刪除或把監聽動作里的代碼都刪掉

Ⅹ java滑鼠點擊panel鍵盤監聽失效

先定義一個全局的靜態變數 static bool canClick=ture；
1.滑鼠右鍵點擊的事件前加個if判斷：
if（canClick）{
滑鼠點擊事件事件
}

2.然後添加鍵盤事件implements KeyListener
在重寫的方法的keyPressed中加入:
if(e.getKeyCode()==KeyEvent.VK_CONTROL){
canClick=false;
}
在重新的方法的keyReleased中加入:
if(e.getKeyCode()==KeyEvent.VK_CONTROL){
canClick=true;
}
