9 Managing and Sh aring Application Data in GUIDE

You cannot close the Co lo r Pale tte and Tool P a lette windows by directly

clicking their close button (X).

In the next example, you set the output of Icon Editor to be the

CData of the

icon. The opening f unction for Icon Editor, with

uiwait, contains this code:

% in Icon E dito r

function gui de_i coneditor_OpeningFcn(hO bject, eventdata, . ..

handles, varar gin)

handles.colorPalette = guide_co lorpalette();

handles.toolPalette = guide_too lpalette('iconEditor', hObject);

% Update handles structure

guidata(hObject, handles);

uiwait(hObject);

As a result, you must call uiresume on each exit path:

% in Icon E dito r

function but tonO K_Callback(hObject, eventdata, handles)

uiresume(handles.figure);

function but tonC ancel_Callback(hObject, eventdata, handles)

% Make sure the return data will be empty if we cancelled

handles.mIconCData =[];

guidata(handles.figure, handles);

uiresume(handles.figure);

function Ico n Editor_CloseRequestFc n(hO bject, eventdata, h andles)

uiresume(hObject);

To ensure that the Color Palette is not closed any other w ay, override its

closerequestfcn to take no action:

% in colorPalette
