matlab制作GUI界面时，滑动条怎么设置？

你可以在进行相应的 *** 作时设置滑动条的属性为on/off

照你的意思，亮度调节按钮按下后，set(h,'enable',’on‘)%h

滑动条对应的句柄

其他情况下，set(h,'enable',’off‘)%h

滑动条对应的句柄

h=figure('unit','normalized','name','Slider')

hsl=uicontrol('parent',h,'unit','normalized','style','slider','position',[.01.53 . 3 .04],'min',0,'max',5)

ht1=uicontrol('parent',h,'unit','normalized','style','text','string','05','position',[.01 .57 .3.04],'fontsize',10)

ht2=uicontrol('parent',h,'unit','normalized','style','text','position',[.01.71 .3 .03])

set(hsl,'callback',['a1=get(hsl,''value'')'...

'set(ht2,''string'',a1)'])
