The iconEditor GUI.

The iconEditor function calls colorPalette only once and

specifies its parent to be a panel in the iconEditor.

% Host the ColorPalette in the PaletteContainer and keep the

% function handle for getting its selected color for editing

% icon.

mGetColorFcn = colorPalette('parent', hPaletteContainer);

This call creates the colorPalette as a component of the iconEditor and then

returns a function handle that

iconEditor can call to get the currently selected

color.

The iconEditor’s

localEditColor helper function calls mGetColorFcn, the

function returned by

colorPalette, to execute the colorPalette’s

getSelectedColor function.

function localEditColor

% helper function that changes the color of an icon data

% point to that of the currently selected color in

% colorPalette

if mIsEditingIcon

pt = get(hIconEditAxes,'currentpoint');

x = ceil(pt(1,1));

y = ceil(pt(1,2));

color = mGetColorFcn();

% update color of the selected block

mIconCData(y, x,:) = color;

localUpdateIconPlot();
