Hi Yair:

Thank you for your contribution, it is an excellent work, if my figure is a GUI (created by GUIDE), how should I change my customized Toolbar’s backgroundcolor? suppose my Toolbar’s Tag is uitoolbar1, thank you very much.

@Zheng – follow the steps outlined in the article, simply modify

hToolbar = findall(hFig,'tag','FigureToolBar');

to:

hToolbar = findall(handles.hObject,'tag','uitoolbar1');

in your *_OutputFcn() function that is generated by GUIDE.

The rest of the code in my article should follow this line (use handles.hObject wherever it says hFig in my article).

Dear Yair, thank you very much for your timely reply, your suggestion gave me a very critical help, wish you good luck.

Dear Yair:

I put the two techniques ( ^[15] and ^[16]) designed by you together, I hope to change the background while floating the toolbar, this effect has been achieved in function, but there are a few small issues to be resolved, the questions are as follows:
(1) How should I do to specify the location of the toolbar while floating? unfortunately, my way (jTbar.getUI.setFloating(true,java.awt.Point(0,0));) does not work;
(2) How should I do to control the emergence and disappear of the toolbar via right-click menu(for example attached to the current GUI figure)? I currently take a drag-and-off style.

Yours Sincerely.

My code (in the “*_OutputFcn()” that is generated by GUIDE) is as follows:

% --- Outputs from this function are returned to the command line.
function varargout = toolbar_demo_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;
jTbar = get(get(findall(handles.figure_main,'tag','uitoolbar1'),'JavaContainer'),'ComponentPeer');
color = java.awt.Color.red;
jTbar.setBackground(color);
jTbar.getParent.getParent.setBackground(color);
jtbc = jTbar.getComponents;
for idx=1:length(jtbc)
    jtbc(idx).setOpaque(false);
    jtbc(idx).setBackground(color);
    for childIdx = 1 : length(jtbc(idx).getComponents)
        jtbc(idx).getComponent(childIdx-1).setBackground(color);
    end
end
jTbar.setBorderPainted(false);
jFrame = get(handle(handles.figure_main),'JavaFrame');
jFrame.showTopSeparator(false);
jTbCon = jTbar.getParent;
jLayout = java.awt.FlowLayout(0,0,0);
jTbar.setLayout(jLayout);
jTbar.setFloatable(true);
jTbar.getUI.setFloating(true,java.awt.Point(0,0));
jCpts = jTbar.getComponents;
for i = 1 : length(jCpts)
    jMls = jCpts(i).getMouseListeners;
    for j = 1 : length(jMls)
        if ~isempty(strfind(get(jMls(j),'type'),'FlyOverListener'))
            jCpts(i).removeMouseListener(jMls(j))
            jCls = jCpts(i).getChangeListeners;
            if ~isempty(strfind(get(jCls(1),'type'),'FlyOverListener'))
                jCpts(i).removeChangeListener(jCls(1))
            end
        end
    end
end
hjTbar = handle(jTbar,'CallbackProperties');
dockUndockCallbackFcn(hjTbar,1,jTbCon)
set(hjTbar,'AncestorAddedCallback',{@dockUndockCallbackFcn,jTbCon});

function dockUndockCallbackFcn(src, ~, jTbc)
if src.isFloating
    jWin = src.getTopLevelAncestor;
    jWin.setResizable(true)
    jWin.setPreferredSize(java.awt.Dimension(450,57));
    jWin.setSize(java.awt.Dimension(450,57));
    jTbc.setVisible(false)
    set(jWin,'WindowClosingCallback',@(~,~)jTbc.setVisible(true))
end

Which polar coordinate system did you use for your solution in MATLAB 2013?

I am trying to integrate your code to MATLAB 2016b `polaraxes` + `warp` in the thread here ^[17]

I used a standard radar-plot layout: North is up (0/360 degs); South is down (180 degs); degrees increasing clockwise from top (North pole).
