How to Run A Gui From Another Gui Tab In Matlab?

To run a GUI from another GUI tab in MATLAB, you can follow these steps:

1. Create the main GUI with tabs using the uitabgroup and uitab functions.
2. Inside one of the tabs, create a button or some other user interface element that will trigger the opening of the secondary GUI.
3. Define a callback function for the button or user interface element. This function will be responsible for creating and launching the secondary GUI.
4. In the callback function, create the secondary GUI using the figure function.
5. Add all necessary graphical elements to the secondary GUI, such as buttons, text boxes, or plots.
6. Make sure to define callback functions for any interactive elements in the secondary GUI as needed.
7. Launch the secondary GUI using the uiwait function. This will prevent the callback function from returning control to the main GUI until the secondary GUI is closed.
8. After the secondary GUI is closed, continue with any necessary operations in the main GUI.

By following these steps, you can run a GUI from another GUI tab in MATLAB. Remember to define the necessary callbacks and ensure proper communication and synchronization between the two GUIs if needed.

How to display plots in a Matlab GUI?

To display plots in a Matlab GUI, you can use the "axes" object in the GUI figure window.

Here is a step-by-step guide:

1. Create a new figure window using the "figure" command. This will be the main window of your GUI.

1

fig = figure('Name', 'My GUI');

1. Create an "axes" object within the figure window to display the plot. You can use the "axes" command and specify the position of the axes within the figure window as a normalized value.

1

ax = axes('Parent', fig, 'Position', [0.1 0.1 0.8 0.8]);

1. In your GUI code, write the plot function or script that generates the plot you want to display. Instead of using the "plot" command to directly display the plot in the figure window, use the "plot" command with the "Parent" property set to the "axes" object created in the previous step.

1
2
3

x = -pi:0.1:pi;
y = sin(x);
plot(ax, x, y);

1. Update the GUI layout to ensure that the plot is correctly displayed within the figure window by calling the "drawnow" command after updating the plot.

1

drawnow;

By following these steps, you can display plots within a Matlab GUI using an "axes" object.

How to add progress bars to Matlab GUI?

To add progress bars to a MATLAB GUI, you can use the uifigure and uitab functions to create the main GUI window. Then, you can use the uiProgressBar function to create progress bars and update their values as needed.

Here is an example of how to do this:

1. Create a new MATLAB function and define a function named createGUI.
2. Inside the createGUI function, use the uifigure function to create the main GUI window:

1
2
3
4
5

function createGUI
    % Create the main GUI window
    fig = uifigure('Name', 'Progress Bars Example', 'Position', [100 100 400 300]);
    tabGroup = uitabgroup(fig);
    tab = uitab(tabGroup, 'Title', 'Progress Bars');

1. Inside the createGUI function, use the uiProgressBar function to create the progress bar:

1
2

    % Create a progress bar
    progressBar = uiProgressBar(tab, 'Position', [50 150 300 20]);

1. Define a function named updateProgressBar that updates the progress bar value. This function will take the progress bar object and the new value as inputs:

1
2
3
4

function updateProgressBar(progressBar, newValue)
    progressBar.Value = newValue;
    drawnow;
end

1. Inside the createGUI function, add a button that updates the progress bar value when clicked:

1
2

    % Add a button that updates the progress bar
    updateButton = uibutton(tab, 'Text', 'Update Progress Bar', 'Position', [150 100 100 40], 'ButtonPushedFcn', @(src,event)updateProgressBar(progressBar, 50));

1. Finally, call the createGUI function to create and display the GUI:

1
2
3

    % Call the createGUI function to display the GUI
    createGUI;
end

1. Save the MATLAB file and run it in the MATLAB command window.

This example creates a GUI window with a single tab that contains a progress bar and a button. When the button is clicked, the value of the progress bar is updated to 50. You can modify this example to add multiple progress bars and update their values as needed.

How to create modal dialogs in Matlab GUI?

To create modal dialogs in MATLAB GUI, you can use the following steps:

1. Create a new figure window for the modal dialog using the figure function. Set the 'WindowStyle' property of the figure to 'modal' to make it a modal dialog window.

1

dlg = figure('WindowStyle', 'modal');

1. Create any necessary UI elements within the dialog window using the available UI components in MATLAB, such as buttons, checkboxes, edit boxes, etc.

1

button = uicontrol(dlg, 'Style', 'pushbutton', 'String', 'OK', 'Position', [10 10 60 30]);

1. Set the 'DeleteFcn' callback property of the dialog window so that it is deleted when closed.

1

set(dlg, 'DeleteFcn', 'delete(gcbf)');

1. To display the modal dialog, use the uiwait function in combination with the waitfor function to wait for its completion or closure.

1

uiwait(dlg);

1. Inside the callback function of any controls within the dialog, you can perform the required actions (e.g., get user input, update data, etc.), and then close the dialog window using the close function.

1

set(button, 'Callback', @(~,~) myCallbackFunction(dlg));

1
2
3
4
5
6
7

function myCallbackFunction(dlg)
    % Perform actions with user input/store data
    % ...
    
    % Close the dialog
    close(dlg);
end

Note: It's important to call uiresume after the uiwait call if you want to resume the execution of the GUI after the modal dialog is closed.

1

uiresume(dlg);

This way, a modal dialog will be created in your MATLAB GUI, and the user will not be able to interact with other parts of the GUI until the dialog is closed.

How to implement drag and drop functionality in Matlab GUI?

To implement drag and drop functionality in a MATLAB GUI, you can follow these steps:

1. Create the GUI using the MATLAB GUIDE tool or by writing code.
2. Add a component (e.g., pushbutton, listbox, or axes) that can be dragged and dropped within the GUI. This component will be referred to as the draggable object.
3. Write a callback function that handles the dragging and dropping functionality. This callback function should be triggered when the user starts dragging the draggable object.
4. In the callback function, use the MATLAB drag'n'drop API to capture the dragging event and determine the new position of the draggable object.
5. Update the position of the draggable object based on the new position calculated in the previous step.

Here is an example implementation of drag and drop functionality for a draggable pushbutton in a MATLAB GUI:

1. Create a new GUI using the MATLAB GUIDE tool and add a pushbutton component.
2. In the opening function of the GUI, store the initial position of the pushbutton using the 'UserData' property.

1
2
3

function pushbuttonDraggable_OpeningFcn(hObject, eventdata, handles, varargin)
% Store the initial position of the pushbutton
set(handles.pushbuttonDraggable, 'UserData', get(handles.pushbuttonDraggable, 'Position'));

1. Add the 'WindowButtonMotionFcn' callback to the GUI's figure to continuously detect mouse movement while dragging.

% --- Executes on mouse motion over figure - except title and menu bar.
function figureDraggable_WindowButtonMotionFcn(hObject, eventdata, handles)
% Check if the pushbutton is being dragged
if isequal(get(handles.figureDraggable, 'currentPoint'), get(handles.figureDraggable, 'UserData'))
    % Get the position offset
    offset = get(handles.pushbuttonDraggable, 'Position') - get(handles.pushbuttonDraggable, 'UserData');
    % Calculate new position
    newPosition = get(handles.pushbuttonDraggable, 'UserData') + offset;
    % Update the position of the pushbutton
    set(handles.pushbuttonDraggable, 'Position', newPosition);
end

1. Add the 'ButtonDownFcn' callback to the pushbutton to start the dragging operation when it is clicked.

1
2
3
4

% --- Executes on button press in pushbuttonDraggable.
function pushbuttonDraggable_ButtonDownFcn(hObject, eventdata, handles)
% Store the initial position of the mouse click
set(handles.figureDraggable, 'UserData', get(hObject, 'Position'));

Now, when you run the GUI, you should be able to drag and drop the pushbutton within the figure window.
