Retrieve variables from inputdlg in a GUI
显示 更早的评论
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};

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
