我做了一個GUI，獲取2個元素：文件（文件列表）和選項（我將在後面解釋）。matlab：關閉GUI如果用戶按下關閉按鈕
有調用下面的功能的功能：
// 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.
對於每個圖像，在函數「mainGUI」（但每次創建GUI，一個GUI被顯示，直到用戶按下「下一「）。
我想要做的下一件事：
如果用戶在GUI中按下關閉按鈕，我想阻止其他GUI-S的顯示和設置「數據= 0」。然後，我將檢查返回的元素（'mydata'）是什麼，如果它等於0，我會知道用戶關閉了GUI，我將根據需要採取行動。
我試圖通過'cmdClose_Callback'來做到這一點，但它不起作用。
假設'文件'=兩個圖像，所以這是第一個圖像的GUI。
我按下關閉按鈕：
，並獲得第二圖像的GUI，儘管封閉第一圖像的圖形用戶界面。
我想，當我關閉GUI，其他GUI-S不會出現。
這是我的代碼：
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」有兩個圖像，我推「下一步」按鈕，第一個數字，並在第二個數字我關閉，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
上面的行：hOptsGUI = secondaryGUI（hFig，options，k，length（files））; 我試圖把一些線。爲了testthe行，我打印一個合適的消息：
if (ishandle(hFig))
disp('exists');
else disp('was closed');
end;
，但它不工作：/
每個GUI用戶將關閉，接下來的回調將被稱爲：
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
，所以我只需要知道在未來的「for循環」如果這個回調被稱爲：
for k=1: length(files)
我該怎麼做？
'delete（hFig）'幫助你嗎？ – Derek
不，它不會：/我試圖把刪除（hfig）放在mainGUI函數中的'callback'這一行。感謝你的努力。 –
