hello,

i am trying to do an imput dialog where i ask the path to two files, and also have a drop down menu with three options.

something like this:

prompt_1= {'Input Path', 'Output Path'};

dlg_title_1 = 'Results files';

num_lines_1 = 1;

defaultans_1={'C:\','C:\'};

answer_1 = inputdlg(prompt_1,dlg_title_1,num_lines_1,defaultans_1);

with also a third line with a drop down menu like the following:

uidropdown(answer_1,'Items',{'Option 1','Option 2','Option 3'},'Value','Option 1');

i have found this question already answered but i couldnt understand it :/ (https://fr.mathworks.com/matlabcentral/answers/386361-combining-inputdlg-with-listdlg)

i can not get how to combine them, if someone could clarify me/help me understand would appreciate it :)

The easiest is probably to create a tiny GUI. More general tips can be found here, but the basic idea is something like the code below. I left adding comments and text fields to you.

function [str1,str2,opt]=inputdialog
hfig=figure('CloseRequestFcn',@close_req_fun,'menu','none');
opt_list={'Option 1','Option 2','Option 3'};
defaultans='C:\';
%set defaults
str1=defaultans;
str2=defaultans;
opt=opt_list{1};
%create GUI
set(hfig,'menu','none')
field1=uicontrol('Style', 'Edit', 'String', str1, ...
    'Parent',hfig,'Units','Normalized', ...
    'Position', [.1, .75, .8, .15]);
field2=uicontrol('Style', 'Edit', 'String', str2, ...
    'Parent',hfig,'Units','Normalized', ...
    'Position', [.1, .55, .8, .15]);
dropdown=uicontrol('Style', 'popupmenu', 'String', opt_list, ...
    'Parent',hfig,'Units','Normalized', ...
    'Position', [.1, .35, .8, .15]);
uicontrol('Style', 'pushbutton', 'String', 'OK', ...
    'Parent',hfig,'Units','Normalized', ...
    'Position', [.1 .1 .35 .2],...
    'Callback','close(gcbf)');
cancel=uicontrol('Style', 'pushbutton', 'String', 'cancel', ...
    'Parent',hfig,'Units','Normalized', ...
    'Position', [.55 .1 .35 .2],...
    'Tag','0','Callback',@cancelfun);
%wait for figure being closed (with OK button or window close)
uiwait(hfig)
%figure is now closing
if strcmp(cancel.Tag,'0')%not canceled, get actual inputs
    str1=field1.String;
    str2=field2.String;
    opt=opt_list{dropdown.Value};
end
%actually close the figure
delete(hfig)
end
function cancelfun(h,~)
set(h,'Tag','1')
uiresume
end
function close_req_fun(~,~)
uiresume
end

hello,

thanks! i understand a little bit more, but the function it returns only one entry and not the three inputs that i dont get why not as it is defined in the str1/str2 and opt variables no?
