我制作了一个包含 2 个元素的 GUI：文件（文件列表）和选项（我稍后会解释）。
有一个函数调用下面的函数：
// 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.
对于每个图像，GUI 在函数“mainGUI”中创建（但每次都会显示一个 GUI，直到用户按下“下一步”）。
我想做接下来的事情：
如果用户按下 GUI 中的关闭按钮，我想停止显示其他 GUI-s 并设置“数据 = 0”。然后，我将检查返回的元素（'mydata'）是什么，如果它等于 0，我将知道用户关闭了 GUI，我将根据需要采取行动。
我试图通过“cmdClose_Callback”来做到这一点，但它不起作用。
假设“文件”=两个图像，所以这是第一个图像的 GUI。
我按下关闭按钮：
尽管关闭了第一个图像的 GUI，但得到了第二个图像的 GUI。
我希望当我关闭 GUI 时，其他 GUI-s 不会出现。
这是我的代码：
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
如果“文件”有两个图像，我按下第一个图的“下一步”按钮，在第二个图中我关闭，我得到：
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
行上方：hOptsGUI = secondaryGUI(hFig, options, k, length(files)); 我试着放一些线。为了测试线条，我打印了一条合适的消息：
if (ishandle(hFig))
disp('exists');
else disp('was closed');
end;
但它不起作用：/
对于用户将关闭的每个 GUI，将调用下一个回调：
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
所以我只需要在下一个“for循环”中知道是否调用了这个回调：
for k=1: length(files)
我怎样才能做到这一点？
