第詳解Matlab中自帶的Java操作合集目錄1獲取鼠標(biāo)在全屏位置2獲取當(dāng)前剪切板內(nèi)容3內(nèi)容復(fù)制到剪切板4獲取鼠標(biāo)處像素顏色5獲取屏幕截圖6創(chuàng)建java窗口（并使其永遠(yuǎn)在最上方）7透明窗口

1獲取鼠標(biāo)在全屏位置

屏幕左上角為坐標(biāo)原點(diǎn)，獲取鼠標(biāo)位置和獲取鼠標(biāo)像素顏色建議和while循環(huán)或者timer函數(shù)結(jié)合使用：

importjava.awt.MouseInfo;

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

mousepoint=[mousepoint.x,mousepoint.y]

2獲取當(dāng)前剪切板內(nèi)容

importjava.awt.Toolkit

importjava.awt.datatransfer.DataFlavor

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

clipTf=clip.getContents([]);

clipContent=clipTf.getTransferData(DataFlavor.stringFlavor)

3內(nèi)容復(fù)制到剪切板

importjava.awt.Toolkit;

importjava.awt.datatransfer.StringSelection;

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

contentStr='歡迎關(guān)注slandarer隨筆';

tText=StringSelection(contentStr);

clip.setContents(tText,[]);

4獲取鼠標(biāo)處像素顏色

需要和獲取鼠標(biāo)位置的函數(shù)結(jié)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獲取屏幕截圖

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創(chuàng)建java窗口（并使其永遠(yuǎn)在最上方）

importjava.awt.Frame;

importjava.awt.Point;

frame=Frame();

%設(shè)置java窗口大小

frame.setSize(400,300)

%設(shè)置java窗口位置

point=Point(300,200);

frame.setLocation(point)

%使其永遠(yuǎn)在最上方

frame.setAlwaysOnTop(true);

%設(shè)置窗口關(guān)閉回調(diào)(不設(shè)置的話javaframe將無法關(guān)閉)

hjWindow=handle(frame,'CallbackProperties');

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

%顯示java窗口

frame.setVisible
