Matlab GUI - 将弹出菜单中选择的图像显示到轴

Question

我需要在弹出菜单中选择的轴上显示图像。 我使用以下代码动态生成弹出菜单列表：

function popupmenu1_Callback（hObject，eventdata，handles）

DirEntries = dir（＆＃39; C：\ Users \ User \ Desktop \ Project \ Images＆＃39;）; uicontrol（＆＃39; Style＆＃39;，＆＃39; popup＆＃39;，＆＃39; String＆＃39;，{DirEntries.name}）;

现在，我在此弹出式菜单中选择的任何图像都应显示在＆＃39;轴中

任何人都可以帮我了解如何在GUI中显示所选图像

Answer 1

此代码应该完成工作

function script
figure;
directory = 'C:\Users\User\Desktop\Project\Images';
Dir = dir(directory);

axes;
h = uicontrol('Style','popup', 'String', {Dir.name}, 'Callback', @popupmenu1_Callback);
setappdata(h,'Dir', directory);



function popupmenu1_Callback(hObject, eventdata, handles)
value = get(hObject, 'Value');
directory = getappdata(hObject, 'Dir');
images = get(hObject, 'String');
% Do a check if this is a valid image
imshow(strcat(directory,'/', images{value}));
