Hi Lukas,
I understand that you are trying to change color of the progress-bar of the “waitbar” figure.
However, I did not find any inbuilt functionality to change the colour of the moving bar of the “waitbar”. But, I found that the workaround suggested in the following answer works to overcome this issue:
The solution mentioned in this thread requires setting “setStringPainted” member of the underlying java object to “true”. This means that the percentage of waiting done will appear as a string on the progress-bar. Alternatively, you can customize the appearance of the MATLAB "waitbar" figure by directly accessing and modifying the underlying Java Swing component. The "waitbar" contains a “javax.swing.JProgressBar” embedded within its “hgjavacomponent”. Once you obtain this component, you can adjust its appearance by setting various properties, such as foreground color. You may use the following code for refernce:
h = waitbar(0, 'message string');
javaComponent = findall(h, 'Type', 'hgjavacomponent');
if ~isempty(javaComponent)
% Get the JProgressBar in the hierarchy
progressBar = javaComponent.JavaPeer;
% Chnage the progress bar color using UI customization
if ~isempty(progressBar)
% Create a custom UI delegate to change the color
ui = javax.swing.plaf.metal.MetalProgressBarUI();
progressBar.setUI(ui);
% Set the progress bar color
progressBar.setForeground(java.awt.Color(1, 0, 0)); % Set to red color
else
disp('JProgressBar not found.');
end
end
% Driver code to visualize the waitbar
for i = 1:100
pause(0.05); % Simulate some process
waitbar(i/100, h, sprintf('Progress: %d%%', i));
end
% Close the waitbar
close(h);
I hope this helps!
