How can I get rid of these problems fullscreen, browser from a file and efficiency

Hi;

I am designing slideshow interface with guide. But I have some problems ;

• 1) How to make fullscreen guide ( I've tried Yair's metod and it did not work ) and ( set(gcf, 'units','norm','Outerposition',[0 0 1 1]) as well.
• 2) For the slideshow, I have to select a file which contains images. But I can open just specific file that I declared (***** myFolder = 'C:\Users\Atacan\2015-09-27'; ****** line 122). I need to access other files. I could not find way to do this.
• 3) When I run this code can not detect my commands(bush and toggle buttons) immediately. Is there any advice to make it more efficient or better way to this.( I have i7 processor and 16 gb ram)

If you find any problem please let me know.

Notes about the code;

If there is no image or end of the slideshow screen is become black. Black.jpg for this reason.

If the show end, time will be 0:0:0.

Answer of 2nd question

myFolder = PathName;
filePattern = fullfile(myFolder, '*.jpg');
jpegFiles = dir(filePattern);
baseFileName = jpegFiles(k).name;
fullFileName = fullfile(myFolder, baseFileName);
imageArray = imread(fullFileName);
imshow(imageArray);

1. I use Yair's maximize figure function, attached, and it works well. What operating system are you using?

2. Use this code to let the user browse and select a file:

% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = 'C:\Program Files\MATLAB';
if ~exist(startingFolder, 'dir')
  % If that folder doesn't exist, just start in the current folder.
  startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)

3. I don't know exactly what "detect my commands" means. Do you mean that the GUI is not repainted/refreshed/updated immediately? If so, issue the "drawnow" command to force it to update immediately. Otherwise, maybe step through with the debugger. Or else explain what "detect my commands" means.

Instead of having a load image button, why not simply load your image filenames into a listbox? Like this app: MAGIC GUI

[Atacan Tosun]

It is not just an image. it should be Images, typing mistake

[Image Analyst]

OK, the load your images filenames into a listbox so that the user can click on any one that he or she wants.

the thing is I browse a file and images in that folder will show on the screen like slideshow.

I used this code but it is opens myFolder whatever I choose (as a file).

Actually,I am new here. I did not understand the meaning of these codes. I hope someone can help me.

myFolder = 'C:\Users\Atacan\2015-09-27';  %Specific file

if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.jpg');
jpegFiles = dir(filePattern);
 for k=1:length(jpegFiles)
baseFileName = jpegFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  imageArray = imread(fullFileName);
  imshow(imageArray);
 end

[Image Analyst]

OK, but you're just reading a bunch of images from disk and repeatedly overwriting a variable imageArray. You don't even display it or analyze it or anything. What's the point of that? The variable imageArray will contain only the very last file you read.

[Atacan Tosun]

imshow(imageArray);

Answer of 1st question

function varargout = Guide1_1_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;

set(gcf, 'units','normalized','position',[0 0 1 1]);

Under the output Function

I don't know why Yair's method (attached) is not working for you. It should. Can you say why? It works for me and most everyone else.

Your method makes the GUI as large as the screen, but it's not truly maximized, and I often find it's not so well aligned on the screen.
