Hi Abhishek,
To programmatically adjust the width of a panel in MATLAB, you can interact with the underlying Java components that MATLAB uses for its GUI. The following approach allows you to manipulate the width of a panel.
First, you need to get a handle to the Java component that represents your panel. This can be done using the “findjobj” function from the MATLAB File Exchange. Here is the link to download the same:- https://www.mathworks.com/matlabcentral/fileexchange/14317-findjobj-find-java-handles-of-matlab-graphic-objects
After installation, Now we can proceed with the following example on how you can achieve this:
% Create Figure 1
hFig1 = figure('Position', [100, 100, 800, 600]);
% Create Panel 1 in Figure 1 and set its initial position and size
hPanel1 = uipanel('Parent', hFig1, 'Title', 'Panel 1', 'Position', [0, 0, 0.3, 1]);
% Function to adjust the panel width using MATLAB properties
function adjustPanelWidth(hPanel, newWidth)
% Get the current position
pos = get(hPanel, 'Position');
% Set the new width
pos(3) = newWidth;
% Update the panel position
set(hPanel, 'Position', pos);
% Print the new position for debugging
disp('New Position:');
disp(pos);
end
% Adjust the panel width for Panel 1 in Figure 1 to 0.3 (normalized units)
adjustPanelWidth(hPanel1, 0.3);
% Create Figure 2
hFig2 = figure('Position', [100, 100, 800, 600]);
% Create Panel 2 in Figure 2 and set its initial position and size
hPanel2 = uipanel('Parent', hFig2, 'Title', 'Panel 2', 'Position', [0, 0, 0.6, 1]);
% Adjust the panel width for Panel 2 in Figure 2 to 0.6 (normalized units)
adjustPanelWidth(hPanel2, 0.6);
% Optional: Adjust the positions to make sure they are not overlapping
pos1 = get(hPanel1, 'Position');
pos2 = get(hPanel2, 'Position');
pos2(1) = 0; % Set the starting x position of Panel 2 to the leftmost edge (0)
set(hPanel2, 'Position', pos2);
% Print the final positions for debugging
disp('Final Position Panel 1:');
disp(get(hPanel1, 'Position'));
disp('Final Position Panel 2:');
disp(get(hPanel2, 'Position'));
The “adjustPanelWidth” function takes the panel handle and a new width as input. You can try it out in your use case.
Hope it helps!
