I made a GUI that gets 2 elements: files (list of files) and options (I will explain later).
there is a function that calls the function below:
// asume that this is my 'options'
options{1} = {'Treatment', 't1', 't2'};
options{2} = {'Tree', '1', '2'};
options{3} = {'Replica', 'r1', 'r2', 'r3'};
// asume that this is my 'files' (may be more than 2 images
files{1} = 'C:\Documents and Settings\erezalon\Desktop\gib_proj_02.10.12\fina3_32bit\IMG_4640.JPG';
files{2} = 'C:\Documents and Settings\erezalon\Desktop\gib_proj_02.10.12\fina3_32bit\grapes03.jpg';
mydata = mainGUI(options, files).
// here I want to check 'mydata'. if it is equal to zero or not.
for each image, the GUI is created in the function ‘mainGUI’ (but each time, one GUI is showed till the user presses ‘next’).
I want to do the next thing:
if the user presses the close button in the GUI, I want to stop the displaying of the other GUI-s and set ‘data = 0’. then, I will check what is the returned element (‘mydata’) and if it’s equal to 0, I will know that the user closed the GUI and I will act as needed.
I tried to do this by the ‘cmdClose_Callback’ but it doesn’t work.
assume that ‘files’ = two images, so this is the GUI of the first image.
I press the close button:
and got the GUI of the second image despite of closing the GUI of the first image.
I want that when I close the GUI, the other GUI-s don’t appear.
this is my code:
function data = mainGUI(options, files)
%# current options
j = 1;
ops = cellfun(@(c) c(1), options, 'Uniform',false);
data{j} = [ops{1:length(ops)}];
j = j + 1;
options = cellfun(@(c) c(2:1:end), options, 'Uniform',false);
clear ops;
ops = cellfun(@(c) c(1), options, 'Uniform',false);
opts = [ops{1:length(ops)}];
%# create main figure, with plot and options button
hFig = figure('Name','window 1','Visible','Off');
a = 1
callback
%# options button callback function
function callback(o,e)
a = 2
%# save current options (sharing data between the two GUIs)
setappdata(hFig, 'opts',opts);
%# display options dialog and wait for it
for k=1: length(files)
hOptsGUI = secondaryGUI(hFig, options, k, length(files));
img = imread(files{k}); %# Read the data from image file data
hAxes = axes('Parent',hOptsGUI,'Units','pixels','Position',[362 242 424 359]); %# so the position is easy to define
image(img,'Parent',hAxes); %# Plot the image
set(hAxes,'Visible','off'); %# Turn the axes visibility off
a = 3
waitfor(hOptsGUI);
a = 4
%# get new options, and update plot accordingly
opts = getappdata(hFig, 'opts');
data{j} = opts;
j = j + 1;
end
end
end
function hFig = secondaryGUI(hParentFig, options, k, num_files)
%# create figure
a = 5
hFig = figure('Name','Step 3 of 4: Choose data for each image','Menubar','none', 'Resize','off', ...
'WindowStyle','modal', 'Position',[300 300 1150 600], 'CloseRequestFcn',@cmdClose_Callback);
set(gcf,'NumberTitle','off')
movegui(hFig, 'center');
options = cellfun(@(c) c(end:-1:1), options, 'Uniform',false);
num = length(options);
%# get saved settings
selected = getappdata(hParentFig, 'opts');
a = 6
%# top/bottom panels
hPanBot = uipanel('Parent',hFig, 'BorderType','none', ...
'Units','normalized', 'Position',[0 0.0 1 0.2]);
hPanTop = uipanel('Parent',hFig, 'BorderType','none', ...
'Units','normalized', 'Position',[0 0.2 1 0.2]);
%# buttongroups in top panel
hBtnGrp = zeros(1,num);
width = 1/num;
for i=1:num
%# create button group
hBtnGrp(i) = uibuttongroup('Parent',hPanTop, ...
'Units','normalized', 'Position',[(i-1)*width 0 width 1]);
%# populate it with radio buttons
height = 1./numel(options{i});
for j=1:numel(options{i})
h = uicontrol('Parent',hBtnGrp(i), 'Style','Radio', ...
'Units','normalized', 'Position',[0.05 (j-1)*height 0.9 height], ...
'String',options{i}{j});
%# set initially selected values
if strcmp(selected{i},options{i}{j})
set(hBtnGrp(i), 'SelectedObject',h)
end
end
end
if k ~= num_files
%# save button in bottom panel
uicontrol('Parent',hPanBot, 'Style','pushbutton', ...
'Units','normalized', 'Position',[0.3 0.2 0.4 0.2], ...
'String','next', 'Callback',@callback);
else
uicontrol('Parent',hPanBot, 'Style','pushbutton', ...
'Units','normalized', 'Position',[0.3 0.2 0.4 0.2], ...
'String','start', 'Callback',@callback);
end
%# save button callback function
function callback(o,e)
a = 7
%# get selected values
hObjs = get(hBtnGrp(:), 'SelectedObject');
vals = get(cell2mat(hObjs),{'String'});
%# update settings
setappdata(hParentFig, 'opts',vals);
close(hFig)
a = 8
end
function cmdClose_Callback(hObject,varargin)
disp(['Close Request coming from: ',get(hObject,'Type')]);
a = 9
%do cleanup here
delete(hFig);
a = 10
end
end
if ‘files’ has two images, I push the ‘next’ button for the first figure, and in the second figure I close, I get:
a = 1
a = 2
a = 5
a = 6
a = 3
a = 7
Close Request coming from: figure
a = 9
a = 10
a = 8
a = 4
a = 5
a = 6
a = 3
Close Request coming from: figure
a = 9
a = 10
a = 4
above the line: hOptsGUI = secondaryGUI(hFig, options, k, length(files));
I tried to put some lines. In order to testthe lines, I print a fit message:
if (ishandle(hFig))
disp('exists');
else disp('was closed');
end;
but it doesn’t work :/
for each GUI that the user will close, the next callback will called:
function callback(o,e)
%# get selected values
hObjs = get(hBtnGrp(:), 'SelectedObject');
vals = get(cell2mat(hObjs),{'String'});
%# update settings
setappdata(hParentFig, 'opts',vals);
%# close options dialog
close(hFig)
end
so I just need to know in the next ‘for loop’ if this callback was called:
for k=1: length(files)
how can I do that?
I succeeded!
I used setappdata and getappdata in order to know if the second callback was called.
@Derek, Derek, thank you very much for your help and that you spent a lot of time for me!
