Save appdesigner windows automatically in user specified folder

Hi ,

I am developing an tool in appdesigner, in which when I select and run one model, new window will open up asking the inputs and if I press continue in that window, one more new window will open up with the respective graphs.

Like that, I have multiple windows will open up based on whether I will continue or exit (using button).

At the end of the program, I need to save all the windows opened into a folder specified by the user,

Please help me with this

In the run button I am writing the code like this

            RunLwrExtModeCal; %The .m file which needs to run
% FolderName = images;   % Your destination folder
FigList = findobj(allchild(0), 'flat', 'Type', 'figure');
for iFig = 1:length(FigList)
  FigHandle = FigList(iFig);
  FigName   = get(FigHandle, 'Name');
  folder = "E:\TATA ELXSI\Calibration_App\images"
  fullFileName = fullfile(folder,FigName,'.fig');

 

  savefig(FigHandle, fullfile(folder, FigName, '.fig'));
end

Hi @Harish M Y,

To ensure that all open figure windows are saved correctly while running an application in App Designer, we can prompt the user to select a destination folder before executing the save operation. This can be achieved by incorporating the following lines of code before the code mentioned in the question:

folder = uigetdir(pwd, 'Select Folder to Save Figures'); 
if folder == 0 
    return; 
end 

This will ensure that the user explicitly selects a valid directory. If the selection is cancelled, the operation will be terminated.

Additionally, the original lines:

folder = "E:\TATA ELXSI\Calibration_App\images" 
fullFileName = fullfile(folder,FigName,'.fig'); 

should be replaced with the following:

if isempty(FigName) 
    FigName = ['Figure_' num2str(iFig)]; 
end  

This modification eliminates the need for hardcoded paths by using the user-defined folder paths and ensures consistent figure naming by assigning a default name using a standard pattern when none is provided.

Furthermore, the original use of:

savefig(FigHandle, fullfile(folder, FigName, '.fig')); 

would create a subfolder named after the figure, rather than saving a .fig file. Replacing it with:

savefig(FigHandle, fullfile(folder, [FigName, '.fig'])); 

ensures that the figure is saved as a file within the specified directory.
