Color Palette

The colorPalette function then defines the valid custom properties in a

3-by-3 cell array.

mPropertyDefs = {... % The supported custom property/value

% pairs of this GUI

'parent', @localValidateInput, 'mPaletteParent';

• The first column contains the property name.

• The second column contains a function handle for the function,

localValidateInput, that validates the input property values .

• The third column is the local variable that holds the value of the property.

colorPalette then initializes the properties with default values.

mPaletteParent = []; % Use input property 'parent ' to initialize

Process the Input Arguments. The processUserInputs helper

function processes the input property/value pairs.

colorPalette calls

processUserInputs before it creates the components, to determine the parent

of the components.

% Process the command line inp ut arguments supplied when

% the GUI is invoked

processUserInputs();

1 processUserI nputs sequences through the inputs, if any, and tries

to match each property name to a string in the first column of the

mPropertyDefs cell array.

2 If it finds a match, processUserInputs assigns the value that was input

for the property to its variable in the third column of the

mPropertyDefs

cell array.

3 processUserI nputs then calls the helper function specified in the second

column of the

mPropertyDefs cellarraytovalidatethevaluethatwas

passed in for the property.
