第11章MATLAB图形用户界面设计

3．建立控件对象举例

（1）建立按钮和双位按钮

程序如下：

pbstart=uicontrol(gcf,Style,push,Position,...

[50,5,60,25],String,StartPlot,...

CallBack,t=-pi:pi/20:pi;plot(t,sin(t)));

ptgrid=uicontrol(gcf,Style,toggle,Position,...

[150,5,60,25],String,Grid,CallBack,grid);

（2）建立单选按钮

程序如下：

set(gcf,Color,R)%设置默认的背景颜色

htxt=uicontrol(gcf,Style,text,String,...

ColorOptions,Position,[200,130,150,20]);

%建立单选按钮

hr=uicontrol(gcf,Style,radio,String,...

Red,Position,[200,100,150,25],Value,1,...

CallBack,[set(hr,Value,1);,set(hb,Value,0);,...

set(hy,Value,0);,set(gcf,Color,R)]);

hb=uicontrol(gcf,Style,radio,String,...

Blue,Position,[200,75,150,25],...

CallBack,[set(hb,Value,1),,set(hr,Value,0);,...

set(hy,Value,0);,set(gcf,Color,B)]);

hy=uicontrol(gcf,Style,radio,String,...

Yellow,Position,[200,50,150,25],...

CallBack,[set(hy,Value,1),,set(hr,Value,0);,...

set(hb,Value,0);,set(gcf,Color,Y)]);

（3）建立复选框

程序如下：

htxt=uicontrol(gcf,Style,text,Position,[200,125,150,25],...

String,SetWindowsProperties);

hp=uicontrol(gcf,Style,check,Position,...

[200,100,150,25],String,MyPosition,...

CallBack,[set(gcf,Position,[10,10,300,250]);,...

ifget(hp,Value)==1,,...

set(gcf,Position,[10,10,600,500]),,end]);

hc=uicontrol(gcf,Style,check,Position,...

[200,75,150,25],String,MyColor,...

CallBack,[set(gcf,color,w);,...

ifget(hc,Value)==1,,set(gcf,color,g),,end]);

hn=uicontrol(gcf,Style,check,Position,...

[200,50,150,25],String,MyName,...

CallBack,[set(gcf,Name,复选框未选中);,...

ifget(hn,Value)==1,,...

set(gcf,Name,复选框被选中),,end]);

（4）建立弹出框

程序如下：

hpop=uicontrol(gcf,Style,popup,String,...

red|blue|green|yellow|white,Position,[100,100,100,80],...

CallBack,[cbcol=[R,B,G,Y];,...

set(gcf,Color,cbcol(get(hpop,Value)))]);

（5）建立列表框

界面中列表框的作用与（4）同，程序如下：

hl=uicontrol
