Retrieve variables from inputdlg in a GUI

Hi,

I have built a GUI where the callback of 'Project Menu' has an input dialog as below code.

The GUI also has a bushbutton which requires the values which were input in the inputdlg.

Is there any way to retrieve the values of 'Project Name' and 'Project Number' to use in the bushbutton callback?

Thanks,

Prompt={'Project Name','Project Number'};
dlg_title='Project Info';
def= {' ',' '};
num_lines = [ones(size(def')) ones(size(def'))*75];
options.Resize='on';
options.Windowstyle='modal';
options.Interpreter='tex';
Project=inputdlg(Prompt,dlg_title,num_lines,def,options);

Yasser - assuming that the user doesn't press cancel, then the project name and number can be retrieved from the cell array Project

projectName = Project{1};
projectNumberAsString = Project{2};

Hi Geoff, Thanks for the answer. If the user presses "OK", I am not sure how we can recall these values for the bushbutton callback. When I use the syntax you recommended, I get an error saying "undefined variable". I need a way to store these values and use them in the bushbutton callback. Bear in mind that inputdlg is not treated as an independent GUI handles. Thanks,

Yasser - isn't the above code in your pushbutton callback? Can you show me how/where this code is called? And please post the entier error message and code.

Hi Geoff,

Please see below a snapshot from the GUI.

The Project info Menu (circled) result in the below dialog input box:

After pressing OK we need to use the Project Name and Project Number input in the "Generate Report" bushbutton.

When using the syntax you recommended in the "Generate Report" callback function, I am getting the below error:

I hope the problem is clear now and appreciate your help.

Yasser - so your input dialog is launched from a menu item? So your current menu button callback may look like

% --------------------------------------------------------------------
function projectinfo_Callback(hObject, eventdata, handles)
% hObject    handle to projectinfo (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

Prompt={'Project Name','Project Number'};
dlg_title='Project Info';
def= {' ',' '};
num_lines = [ones(size(def')) ones(size(def'))*75];
options.Resize='on';
options.Windowstyle='modal';
options.Interpreter='tex';
Project=inputdlg(Prompt,dlg_title,num_lines,def,options);

% <----- Add this code to save the output
if ~isempty(Project)
    handles.projectName = Project{1};
    handles.projectNumberAsString = Project{2};
else
    % handle case where dialog is closed without inputs
    handles.projectName = 'defaultProjectName';
    handles.projectNumberAsString = 'defaultProjectNumber';
end
guidata(hObject, handles);  % <----- saves the updated handles structure

So now the project information is saved to the handles structure. You can then access this data from your pushbutton callback as

if isfield(handles, 'projectName')
    projectName = handles.projectName;
    projectNumberAsString = handles.projectNumberAsString;
    
    % do something
end

Works perfectly.

Thanks Geoff,
