So I created a GUI with one axis, three push buttons and 6 static text fields. Im referring to this example: https://de.mathworks.com/help/imaq/previewing-data.html?s_tid=gn_loc_drop.

My problem is that Im using two gige cameras which means that I need two image handles "hImages" 1 and 2.

This is what I think that I have to use:

vidRes = handles.vid1.VideoResolution;
imWidth = vidRes(1);
imHeight = vidRes(2);
nBands = handles.vid1.NumberOfBands;
hImage1 = image(zeros(imHeight,imWidth,nBands));
vidRes = handles.vid2.VideoResolution;
imWidth = vidRes(1);
imHeight = vidRes(2);
nBands = handles.vid2.NumberOfBands;
hImage2 = image(zeros(imHeight,imWidth,nBands));
setappdata([hImage1, hImage2],'UpdatePreviewWindowFcn',@mypreview_fcn);
setappdata(hImage1,'HandleToTimestampLabel',handles.text1);
setappdata(hImage1,'HandleToResolutionLabel',handles.text2);
setappdata(hImage1,'HandleToStatusLabel',handles.text3);
setappdata(hImage2,'TimestampLabel',handles.text9);
setappdata(hImage2,'ResolutionLabel',handles.text8);
setappdata(hImage2,'StatusLabel',handles.text7);
