详解Matlab中自带的Java操作合集

第详解Matlab中自带的Java操作合集目录1获取鼠标在全屏位置2获取当前剪切板内容3内容复制到剪切板4获取鼠标处像素颜色5获取屏幕截图6创建java窗口（并使其永远在最上方）7透明窗口

1获取鼠标在全屏位置

屏幕左上角为坐标原点，获取鼠标位置和获取鼠标像素颜色建议和while循环或者timer函数结合使用：

importjava.awt.MouseInfo;

mousepoint=MouseInfo.getPointerInfo().getLocation();

mousepoint=[mousepoint.x,mousepoint.y]

2获取当前剪切板内容

importjava.awt.Toolkit

importjava.awt.datatransfer.DataFlavor

clip=Toolkit.getDefaultToolkit().getSystemClipboard();

clipTf=clip.getContents([]);

clipContent=clipTf.getTransferData(DataFlavor.stringFlavor)

3内容复制到剪切板

importjava.awt.Toolkit;

importjava.awt.datatransfer.StringSelection;

clip=Toolkit.getDefaultToolkit().getSystemClipboard();

contentStr='欢迎关注slandarer随笔';

tText=StringSelection(contentStr);

clip.setContents(tText,[]);

4获取鼠标处像素颜色

需要和获取鼠标位置的函数结合。

importjava.awt.MouseInfo;

importjava.awt.Robot;

robot=Robot();

mousepoint=MouseInfo.getPointerInfo().getLocation();

tempColor=robot.getPixelColor(mousepoint.x,mousepoint.y);

RGBColor=[tempColor.getRed(),tempColor.getGreen(),tempColor.getBlue()]

5获取屏幕截图

importjava.awt.Robot;

importjava.awt.Rectangle;

robot=Robot();

rectangle=Rectangle();

screensize=get(0,'screensize');

screensize=1.5*screensize;

rectangle.x=0;

rectangle.y=0;

rectangle.width=screensize(3);

rectangle.height=screensize(4);

image=robot.createScreenCapture(rectangle);

data=image.getData();

temp=zeros(screensize(3)*screensize(4)*3,1);

temp=data.getPixels(0,0,screensize(3),screensize(4),temp);

temp=uint8(temp);

R=temp(1:3:end);

G=temp(2:3:end);

B=temp(3:3:end);

R=reshape(R,[screensize(3),screensize(4)]);

G=reshape(G,[screensize(3),screensize(4)]);

B=reshape(B,[screensize(3),screensize(4)]);

R=R';G=G';B=B';

ima=cat(3,R,G,B);

imshow(ima)

6创建java窗口（并使其永远在最上方）

importjava.awt.Frame;

importjava.awt.Point;

frame=Frame();

%设置java窗口大小

frame.setSize(400,300)

%设置java窗口位置

point=Point(300,200);

frame.setLocation(point)

%使其永远在最上方

frame.setAlwaysOnTop(true);

%设置窗口关闭回调(不设置的话javaframe将无法关闭)

hjWindow=handle(frame,'CallbackProperties');

set(hjWindow,'WindowClosingCallback',@(h,e)frame.dispose());

%显示java窗口

frame.setVisible
