Setting the Initial Color on the Color Palette

After you create all three GUIs, you need to set the initial color. When you

invoke the Color Palette from the Icon Editor, the Color Palette passes a

function handle that tells the Icon Editor how to set the initial color. This

function handle is stored in its

handles structure. You can retrieve the

handles structure from the figure to w hich the Color P alette outputs the

handle:

% in colorPalette

function gui de_c olorpalette_OpeningFcn( hObject, ...

eventdata, ha ndle s, varargin)

handles.output = hObject;

% Set the initial palette c olor to black

handles.mSelectedColor = [0 0 0];

% Publish the function setS electedColor

handles.setColor = @setSelectedColor;

% Update handles structure

guidata(hObject, handles);

% in colorPalette

function set Sele ctedColor(hObject, color)

handles = guidata(hObject);
