14 Examples of UIs Created Programmatically

14-14

View the Example Code

To obtain copies of the program files for this example, follow these steps:

Set your current folder to one to which you have write access.

Copy the example code and display it in the Editor by issuing the following MATLAB

commands:

copyfile(fullfile(docroot, 'techdoc','creating_guis',...

'examples','tableplot.m')),...

fileattrib('tableplot.m', '+w');

edit tableplot.m

Set Up and Interact with the uitable

This example has one file, tableplot.m, that contains its main function plus two local

functions (uicontrol callbacks). The main tableplot function creates a figure and

populates it with uicontrols and one axes.

The function hides the figure's menu bar because it is not needed.

% Create a figure that will have a uitable, axes and checkboxes

figure('Position', [100, 300, 600, 460],...

'Name', 'TablePlot',... % Title figure

'NumberTitle', 'off',... % Do not show figure number

'MenuBar', 'none'); % Hide standard menu bar menus

The main tableplot function sets up the uitable immediately after loading a data

matrix into the workspace. The table's size adapts to the matrix size (matrices for

uitables must be 1-D or 2-D).

% Load some tabular data (traffic counts from somewhere)

count = load('count.dat');

tablesize = size(count); % This demo data is 24-by-3

% Define parameters for a uitable (col headers are fictional)

colnames = {'Oak Ave', 'Washington St', 'Center St'};

% All column contain numeric data (integers, actually)

colfmt = {'numeric', 'numeric', 'numeric'};

% Disallow editing values (but this can be changed)

coledit = [false false false];

% Set columns all the same width (must be in pixels)

colwdt = {60 60 60};
