I have a uibuttongroup with radio buttons defined in it. I have uipanels defined with their corresponding properties. What I want to do is to be able to click one radio button and have one uipanel appear, and then click my other radio button to have the other uipanel appear. Here are snippets of my code:
operation_type_1 = uibuttongroup(S.Test, 'Title', 'Operation Type', 'position', [0 0.3 panel_w/2 0.15]);
uicontrol('Parent',operation_type_1, 'Style', 'radiobutton',...
'String', 'invisible',...
'position', [0 0 0 0], 'Tag', 'invisibutton');
uicontrol('Parent',operation_type_1,'Style','radiobutton',...
'String', 'Time Operation',...
'Position', 100*[0.1 flooring(3.5, 'tp') 1.2 0.15], 'Tag', 'timeop1');
uicontrol('Parent',operation_type_1,'Style','radiobutton',...
'String', 'Volume Operation',...
'Position', 100*[0.1 flooring(2.5, 'tp') 1.2 0.15], 'Tag', 'volumeop1');
This defines my button group and the two radio buttons.
Then I have code which creates a volume panel:
As well as a Time Panel:
These are in the same position. What I want is to be able to click on the "Time Operation" radio button and have the time panel be visible, and when I click on the "Volume Operation" radio button, the volume panel is visible.
I've tried doing switch case statements. I don't get errors, but I don't get results either. For example, my case statements for the time and volume panels are:
switch str
case 'timeop1'
if U.Value; S.result_panel_time1.Visible = 'On';
else S.result_panel_time1.Visible = 'Off';
end
case 'volumeop1'
if U.Value; S.result_panel_volume1.Visible = 'On';
else S.result_panel_volume1.Visible = 'Off';
end
How do I get this to work? I'm not using GUIDE, just coding a MATLAB GUI.
UPDATE
I've tried implementing the callback suggested below, but I get a "Function definition is misplaced or improperly nested." error. I use the following function:
function button_callback(U, varargin{2})
switch get(get(operation_type_1, 'SelectedObject'), 'Tag')
case 'timeop1'
if U.Value; S.result_panel_time1.Visible = 'On';
else S.result_panel_time1.Visible = 'Off';
end
case 'volumeop1'
if U.Value; S.result_panel_volume1.Visible = 'On';
else S.result_panel_volume1.Visible = 'Off';
end
end
end
And I've added the callbacks "...'callback', {#pb_call, S}" to my timeop1 and volumeop1. (Because all of the other function I have are in a .m file called pb_call.m). The function appears to be nested fine but the error points at the exact one.
It seems to me you did not define callback for your RadioButton. For example, set callback for volumeop1:
uicontrol('Parent',operation_type_1,'Style','radiobutton',...
'String', 'Volume Operation',...
'Position', 100*[0.1 0.3 1.2 0.15], 'Tag', 'volumeop1', ...
'Callback', #switchPanel);
Then in function switchPanel, you will set corresponding panel visible, while set others invisible.
This is trying to answer your questions, but it seems to me what you want is uitab.
My partner ended up fixing it:
The callback was {callback, S} and S, U, and str were:
S = varargin{3}; %main figure handle
U = varargin{1}; %current uicontrol
str = char(U.String);
The problem occurred in the radiobutton creation, since the result panels were being created after the radiobuttons could be triggered, thus nothing was made invisible/visible and an error would occur.
However, it would be highly convenient if callbacks could affect all GUI parts, not just previously defined ones. I've tried using guidata in the past, but I had to use other, less straighforward methods to accomplish my goals. I'll try using working samples and building upon those in the future, but currently I am working on another part of the project and will get back to that later.
But using either guidata/setappdata or something related would work here as well as my own solution, which is making sure that the objects you are trying to change are already defined before the button triggering the callback.
(He also posted this answer to where I asked this same question in MATLAB Answers.)
I have added uicontextmenu to the line object. uicontextmenu includes 3 check boxes. whenever I check any of them uicontextmenu disappears. I want uicontextmenu visible for sometime so that i can check multiple boxes and see the change (same as a button group but in uicontextmenu). Is there any solution to this or some other approach?
cmenu=uicontextmenu;
set(he,'uicontextmenu',cmenu);
item1=uimenu(cmenu,'label','Data A','checked','off','callback',#func_a);
item2=uimenu(cmenu,'label','Data B','checked','off','callback',#func_b);
item3=uimenu(cmenu,'label','Data C','checked','off','callback',#func_c);
basically, he is the line object created by plot(x,y) and func_a, func_b, func_c are function to convert property 'checked' to on|off.
This example is greatly inspired by Benoit_11 solution, but a bit refined. I was also under the impression that the 3 different functions in your callback were doing different things so I made the 3 different menus change different properties of the line (instead of changing the same property with different values).
I made the uimenu callback in one single nested function. It decides what to do based on the parameter what2do supplied at the uimenu definition (but feel free to keep 3 separate functions). However, note that the function that toggle the check mark is the same for all uimenu (you don't need a separate function for each of them).
function hf = TestUiContext2
%// Extension of Benoit_11 solution
clear ; clc ; close all
hf = figure ; %// return the handle of the figure
hax = axes; %// Create axes and save handle
plot(rand(20,3)); %// Plot three lines
hcmenu = uicontextmenu; %// Define a context menu; it is not attached to anything
%// Define the context menu items and install their callbacks
item1 = uimenu(hcmenu, 'Label','Bold line' , 'Callback' , {#uiCallback,'bold'} );
item2 = uimenu(hcmenu, 'Label','Dotted line' , 'Callback' , {#uiCallback,'dots'} );
item3 = uimenu(hcmenu, 'Label','Markers on' , 'Callback' , {#uiCallback,'mark'} );
hlines = findall(hax,'Type','line'); %// Locate line objects
for line = 1:length(hlines) %// Attach the context menu to each line
set(hlines(line),'uicontextmenu',hcmenu)
end
function uiCallback(obj,~,what2do)
hline = gco ;
switch what2do
case 'bold'
toggle_bold_line(hline)
case 'dots'
toggle_dotted_line(hline)
case 'mark'
toggle_markers(hline)
end
%// reposition the context menu and make it visible
set(hcmenu,'Position',get(gcf,'CurrentPoint'),'Visible','on')
toggle_checkmark(obj) %// toggle the checkmark
end
function toggle_checkmark(obj)
if strcmp(get(obj,'Checked'),'on')
set(obj,'Checked','off')
else
set(obj,'Checked','on')
end
end
function toggle_bold_line(hline)
if get(hline,'LineWidth')==0.5
set(hline,'LineWidth',2)
else
set(hline,'LineWidth',0.5)
end
end
function toggle_dotted_line(hline)
if strcmpi(get(hline,'LineStyle'),':')
set(hline,'LineStyle','-')
else
set(hline,'LineStyle',':')
end
end
function toggle_markers(hline)
if strcmpi(get(hline,'Marker'),'none')
set(hline,'Marker','o')
else
set(hline,'Marker','none')
end
end
end
Now you can enjoy ticking all your menu in one go ;)
Here is a workaround which might do the trick for you. That's not too elegant but it seems to work.
The trick is to set the menu 'Visible' property to 'on' in every callback you have (i.e. #func_a, #funct_b and #funct_c). When I run the following example (based on the demo on the Mathworks website) the menu does not disappear when the selection is changed. Notice that I created separate functions for each callback.
Here is the code:
function TestUiContext( ~)
%// Based on example from The Mathworks
%// http://www.mathworks.com/help/matlab/ref/uicontextmenu.html
clear
clc
close all
%// Create axes and save handle
hax = axes;
%// Plot three lines
plot(rand(20,3));
%// Define a context menu.
hcmenu = uicontextmenu;
%// Define the context menu items and install their callbacks
item1 = uimenu(hcmenu,'Label','dashed','Callback',#(s,e) hcb1);
item2 = uimenu(hcmenu,'Label','dotted','Callback',#(s,e) hcb2);
item3 = uimenu(hcmenu,'Label','solid','Callback',#(s,e) hcb3);
%// Locate line objects
hlines = findall(hax,'Type','line');
%// Attach the context menu to each line
for line = 1:length(hlines)
set(hlines(line),'uicontextmenu',hcmenu)
end
%// In the callback of every item/option, set the menu property 'Visible' to 'on'.
function hcb1
set(gco,'LineStyle','--');
set(hcmenu,'Visible','on')
end
function hcb2
set(gco,'LineStyle',':');
set(hcmenu,'Visible','on')
end
function hcb3
set(gco,'LineStyle','-');
set(hcmenu,'Visible','on')
end
end
And 2 screenshots to show what it looks like:
And moving the cursor down:
So as I said, not perfect but hopefully it will do the job for you!
I wrote a code like this in Matlab:
function[] = gui_function()
window.value1 = uicontrol('style', 'edit', ...
'string', '5', ...
'callback', #is_number);
window.computeButton = uicontrol('style', 'push', ...
'callback', {#test_script, str2double(get(window.value1, 'string'))});
end
function[] = test_script(varargin)
value1 = varargin{3};
end
I want to pass the text from Edit uicontrol to Button's callback. When I do it as following, the value that is passed is an old value that is set when declaring the uicontrol.
So ie. I run the GUI and have a value of 5 in the edit. I overwrite it to be 20, but after pushing the button, the value that is being passed is still 5
What is wrong in this approach? How can it be done differently?
Thank you in advance!
In my opinion, the best option when working with GUIs is to use the handles structure of the GUI, in which every uicontrols are stored along with their associated properties, in addition to (that's the cool part) whatever you want to store in it, like variables for instance.
So I modified you code a bit to make use of the handles structure. I'm not entirely clear as to what you want, but in my example the pushbutton is used to update the content of a second edit box with the content of the 1st edit box. That's very basic, but it should help you get a feel of handles and the handles structure. If something is unclear please let me know!
function gui_function()
ScreenSize = get(0,'ScreenSize');
handles.figure = figure('Position',[ScreenSize(3)/2,ScreenSize(4)/2,400,285]);
handles.Edit1 = uicontrol('style', 'edit','Position',[100 150 75 50], ...
'string', '5');
handles.Edit2 = uicontrol('style', 'edit','Position',[100 80 75 50], ...
'string', 'Update me');
handles.computeButton = uicontrol('style', 'push','Position',[200 100 75 75],'String','PushMe', ...
'callback', #PushButtonCallback);
guidata(handles.figure, handles); %// Save handles to guidata. Then it's accessible form everywhere in the GUI.
function PushButtonCallback(handles,~)
handles=guidata(gcf); %// Retrieve handles associated with figure.
TextInBox1 = get(handles.Edit1,'String');
set(handles.Edit2,'String',TextInBox1); %// Update 2nd edit box with content of the first.
%// Do whatever you want...
guidata(handles.figure, handles); %// DON'T forget to update the handles structure
You could customize this GUI by adding your function callback (test_script) in the same way I implemented the PushButtonCallback. Hope I understood what you wanted :)
For an user interface I'm programming an uitable. The user chooses an option A,B or C in the first column and the suboption in the second column depends on what was chosen in the first, either A.1,A.2 or A.3 or B.1,B.2 or B.3 or the same for C
The code for the table can be found in Appendix A.
When the user first defines the main option, then automatically the suboptions are reduced accordingly to only valid choices. This is realized by evalulating the CellEditCallback for column 1 and resetting the ColumnFormat for column 2. (function modifySelection in Appendix B)
If the user now realizes he made a mistake and needs to edit a suboption another time, then the ColumnFormat is still set according to the previous edited main option and the valid choices are not available unless he re-chooes the main option another time. (see the blue highlighting in picture).
To resolve this, I also implemented the CellSelectionCallback calling the function justifySelection (in Appendix B), which is checking by selection, which option was chosen in column 1 to offer again the right suboptions for column 2. But as this callback reacts on selection, I need to select twice, one time to trigger the CellSelectionCallback and another to actually get my choices. For large tables, this can be very annoying!
So my question is:
Is there a way to prevent the popup menu in column 2 from popping up, until it found out what's the content of the according column 1, so it immediately offers the valid choices?
Or:
How could I detect a mouse click on a cell and get the row and column-index? But without invoking the following selection and popping up action?
I was already raking all available properties but didn't found anything which could be useful.
Maybe one could do something using the ButtonDownFcn, but how to get the cell indices? What about the BusyAction property, how can that be used for my purpose?
Any ideas?
I'm sorry in advance to bomb you with so much code, it's already the most minimal example, but fully executable, so you can try it out.
Appendix A/B
function fancyUitable
selector_1 = { 'A'; 'B' ; 'C' };
selector_2 = { 'first select first row!' };
h = figure('Position',[200 100 268 120],'numbertitle','off','MenuBar','none');
defaultData = repmat( {'select main option...', 'select suboption...'} ,5,1);
columnname = {'Option ',...
'Suboption '};
columnformat = { {selector_1{:}}, selector_2 };
columneditable = [true true];
t = uitable(h,'Units','normalized','Position',[0 0 1 1],...
'Data', defaultData,...
'ColumnName', columnname,...
'ColumnEditable', columneditable,...
'ColumnFormat', columnformat,...
'RowName',[],...
'CellEditCallback',#modifySelection,...
'CellSelectionCallback',#justifySelection);
set(h,'Tag','Config_figure')
set(t,'Tag','Config_table')
end
% **Appendix B**
% (part of the same function file)
function modifySelection(~,evt_edit)
if evt_edit.Indices(2) == 1
modifyPopup( evt_edit.Indices(1) );
end
end
function justifySelection(~,evt_select)
try %to surpress an unimportant error
if evt_select.Indices(2) == 2
modifyPopup( evt_select.Indices(1) );
end
end
end
and finally the single function modifyPopup which rewrites the Columnformat:
function modifyPopup( row )
id_group_1 = {'A.1';'A.2';'A.3'};
id_group_2 = {'B.1';'B.2';'B.3'};
id_group_3 = {'C.1';'C.2';'C.3'};
id_default = {'select main option first'};
myfigure = findobj('Tag','Config_figure');
config_data = get(findobj(myfigure,'Tag','Config_table'),'Data');
selector = config_data(row,1);
selector = selector{1};
config_format = get(findobj(myfigure,'Tag','Config_table'),'ColumnFormat');
switch selector
case 'A'
config_format{2} = id_group_1';
case 'B'
config_format{2} = id_group_2';
case 'C'
config_format{2} = id_group_3';
otherwise
config_format{2} = id_default;
end
set(findobj(myfigure,'Tag','Config_table'),'ColumnFormat',config_format)
end
Bounty: Why just +50? - I guess it's either not possible or the answer is easy, once one had the right initial idea. I'm not looking a for a complex workaround using java object properties etc. Thank you in advance!
I include the discussion from the comments here to keep the overview:
If you want to try it out, you can copy the code and follow these steps to reproduce the undesired behaviour:
select main option A in the first row.
the suboption in the first row then contains the choices A.1, A.2 and
A.3.
select main option B in the second row, therefore the choices for
the suboption in the second row are B.1, B.2 and B.3
BUT NOW you want to change the suboption in the first row (directly); you would expect to get the choices A.1, A.2 and A.3; but you don't. You get offered B.1, B.2 & B.3; - Because the last main option you selected was B (though in a diffrent row).
It seems that instead of looking for the last option, you should look at the relevant option. So either make sure that clicking on a
suboption does a 'lookup' to see which main option there is,
Thats exactly what I'm looking for! But how could I do that? How to
detect the click, get the column&row indices, set the right
ColumnFormat and then finally let the cell pop up. The only
possibility I see until now is the CellSelectionCallback, but it is
executed after the cell already popped up with the invalid choices.
I'd need a kind of ClickedCallback, like there is for pushbuttons
or make sure that selecting a main option only sets the suboptions for that row.
That's not possible, you can't set a suboption for a certain row as you need to modify ColumnFormat, which affects the whole table and not just one row.
I would not use a uitable; it's just not suited for this sort of thing.
Here's how I would do it:
function GUIdemo
%%// Construct GUI
%// Main figure
mainFig = figure;
set(mainFig, 'Color', get(0, 'DefaultUicontrolBackgroundColor'));
%// Create as many blocks as needed. The only thing you have to do is

%// On changing radiobutton, correct the string list of the popups
set(groups(ii),'SelectionChangeFcn', #(~,~)selectionChangeCallback(ii));
%// This is needed by the OK button callback
popupHandles = popups;
end
%// What happens when clicking a radio button?
%// NOTE: this is a doubly-nested function
function selectionChangeCallback(num)
switch get(groups(num), 'SelectedObject')
case radios(num,1)

The layout is of course still crude, but you get the idea. Of course, the radio buttons can also be replaced by a popup (more compact), three pushbuttons, or whatever else you like.
The contents of the popups are not related to each other, which is exactly the problem with the uitable approach. In this GUI, changes in the popup's contents can be instantaneous when changing a radio button, simply because you have better control over how to deal with changes.
A programming note: I personally don't like it when handles of individual components in what I treat as a "block" are floating around in the top-level function, which is why I use doubly-nested functions -- it's kind of like encapsulation. Now, when used outside of classes, this is not everyone's cup of tea, so you might want to convert them. Of course, all nested functions are trivially converted to subfunctions; you just have to manually pass a lot more information around.
With this approach, you lose some functionality (the ability to re-size your UI elements), but you gain intuitive behavior of the GUI controls. When these are the choices, I've been trained to develop towards the latter option. The nice bells and whistles will only impress the end-user the first few times round, but the program's basic functionality will become more and more important with increased usage. As you noted yourself, this buggy behavior gets annoying when you have to use the tool a lot; I'd say, drop the resizability in favor of improved control behavior.
Though I highly appreciate the effort and the solution of Rody Oldenhuis and he definetely deserved the award, his solution would have required a lot of changes in my code, so I kept trying to find a simpler solution. Here it is, finally 99% bug-free.

The solution is to use the Cell Selection Callback with two UITables in your GUI. Make the first table hold the data of {'a','b','c'} then in the cell selection callback, make the second UITable visible and set its data based on the cell selection properties of the first UITable.

I have generated a popup menu without using GUIDE by using following code which works well:
figure;
row=4;
String =sprintf('Video%d#', 1:row);
String(end) = [];
CString=regexp(String , '#' , 'split');
uicontrol('style','popupmenu' , ...
'String' , CString ,...
'Position' , [200,400,12,24]);
My problem is its callback function, I can not assign any function to that to have any action when I press any of it's option.
I will appreciate that anyone help me.
I found this question because I was basically having the same problem. Even if this is (at the time of writing this answer) more than 1 year old, I am posting my solution hoping that it will help the posterity.
You can get the value of the property Value of your pop-up menu: that is basically the position, in the array of the possible choices that populate your pop-up menu, of the selected choice.
It is easier to code than to explain in words, so an example code follows. Just copy/paste this code into a plain text file with .m extension, and run it in Matlab.
function popupexample
% create an empty figure
h_fig = figure;
% create a popup menu
