12 Examples of GUIs Created Programmatically

12-12

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

mPlotTypes

is a 5-by-2 cell array that holds the data to be plotted in the axes.

The first column contains the strings that are used to populate the pop-up

menu. The second column contains the functions, as anonymous function

handles, that create the plots.

mPlotTypes = {... % Example plot types shown by this GUI

'plot(rand(5))', @(a)plot(a,rand(5));

'plot(sin(1:0.01:25))', @(a)plot(a,sin(1:0.01:25));

'bar(1:.5:10)', @(a)bar(a,1:.5:10);

'plot(membrane)', @(a)plot(a,membrane);

'surf(peaks)', @(a)surf(a,peaks)};

Because the data is created at the top level of the GUI function, it is available

to all callbacks and other functions in the GUI.

See Anonymous Functions in the MATLAB documentation for information

about using anonymous functions.

Creating the GUI and Its Components

Like the data, the components are created at the top level so that their handles

are available to all callbacks and other functions in the GUI.

The Main Figure

The following statement creates the figure for GUI.

hMainFigure = figure(... % The main GUI figure

'MenuBar','none', ...

'Toolbar','none', ...

'HandleVisibility','callback', ...

'Color', get(0,...

'defaultuicontrolbackgroundcolor'));
