; set1: 100 images）。
最初，我使用set2: 25 images选择100张图片中的popupmenu，然后使用set1查看这些图片。
假设我的slider一分为slider value。
现在，如果我使用56选择popupmenu的{{1}}。
set2。
25 images有没有办法根据我的as the slider value is 56 (> max: 25), the slider control is disappearing选项重置滑块。
我使用Warning: 'slider' control cannot have a 'Value' outside of 'Min'-'Max' range
Control will not be rendered until all of its parameter values are valid
将popmenu转换为flag
popmenu selection现在，当我使用get获取值时，它也大于25：
slider_callback有什么建议吗？
由于
答案 0 :(得分：0)
我能够弄清楚这一点，以防万一其他人有类似的问题：
value = int32(get(hObject,'Value'));
if value == 0 || maxNumberOfImages == 1
value = 1;
elseif value > maxNumberOfImages
value = maxNumberOfImages;
end
disp(value);
set(handles.sliderC, 'Value', value);
如果该值大于maxNumberOfImages，我会再次将当前handle value设置为maxNumberOfImages，这会像我预期的那样重置滑块控件而不会禁用滑块。
