I am using app designer in Matlab 2018a and I replaces a button for upload image. When I push the button a screen open for select an image then when I select image the gui minimize but it's working because when I maximized it the image showing on axis.

This is the code in function..

  [FileName, FilePath]= uigetfile({'*.jpg','*.bmp'}, 'Select a file');
            if isnumeric(FileName);  return; end 
            image = imread(fullfile(FilePath, FileName));
            imshow(image,'parent',app.axes);

在 MATLAB Online 中打开

figure(app.UIFigure);

This should reopen the GUI windown after it minimises.

The problem is not with imshow() rather it is with uigetfile() function. I was also facing same issue with GUI built with both guide and appdesigner. Your solution works for me. Thanks!

imshow() resizes the figure under the condition that "hold" is off and the axes is in the "default" position as-if it is the only axes in the figure.

To avoid this, either turn hold on for the axes, or make the axes a non-default size, or else (my recommendation) do not use imshow() for any purpose other than interactive exploration.
