Icon Editor

mIconWidth = 16; % Use input property ' iconwidth' to initialize

mIconHeight = 16; % Use input property 'ic onheight' to initialize

mIconFile = fullfile(matlabroot,'/toolbox/matlab/icons/');

The values of mIconWidth and mIconHeight are interpreted as pixels. The

fullfile function builds a full file name from parts.

Process the Input Arguments. The

processUserInputs helper function

processes the input property/value pairs.

iconEdit calls proc essUserInputs

after the layout is complete and just before it needs the inputs to initialize

the GUI.

% 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.

Retrieve Output on Return from a GUI

If you call iconEditor with an output argument, it returns a truecolor image

as an n-by-m-by-3 array.

The data definition section of the code creates a cell array to hold the output:

mOutputArgs = {}; % Variable for storing output when GUI returns

Following the call to uiwa it, w hich stops the sequential execution of the

code file, iconEdit assigns the constructed icon array,

mIconEdit,tothecell

array

mOutputArgs and then assigns mOutputArgs to varargout to return

the arguments.
