MATLAB: How to add a callback function to mouse-click event inside a Simulink model but outside any block or line

callbackMATLABmouse clicksimulink

HI, I am creating a plugin tool for Simulink to help users during model development. When creating their Simulink model in Simulink workspace/window, whenever the user clicks somewhere inside the simulink workspace (but outside any block or line), I need to execute a callback function. How do I do this?

PS. I was able to add callback functions to blocks (by temporarily overriding their 'openfcn' function). I need something simillar so that I can execute a callback function when the user clicks outside of any block, but still inside the simulink workspace.

I NEED TO CALL THE CALLBACK FUNCTION WHEN CREATING THE SIMULINK MODEL, NOT WHILE RUNNING A SIMULATION.

Thank you!

Hi Stozaki,

Thank you very much for your solution! I appreciate your efforts to create testmodel.slx.

Actually, I was looking for a way just to capture the mouse click event on the Simulink canvas (blank area), not in a particular block/line/annotation, so that I can trigger some function. Perhaps, Simulink does not allow this (I don't know).

Your solution still requires creating an annotation element, which is not the best solution to my use-case, but is something I can settle with.

Thank you very much!

MATLAB: How to create custom buttons that perform certain tasks in a Simulink block diagram

You can use masked Subsystem blocks with appropriately defined callbacks as custom buttons in a Simulink block diagram. There are several examples of this implementation in the demo models provided with Simulink. The attached example further illustrates this approach:

1. Save and open the attached model, cbut.mdl, in MATLAB.

2. Select the block named "Action 1".

3. Select "Block Properties" from the Simulink "Edit" menu. The "Action 1" Block Properties dialog box appears.

4. Click the "Callbacks" tab and then select the "OpenFcn" callback from the "Callback functions list". The dialog displays the contents of the OpenFcn callback function. Observe that the callback function uses the DISP command to display a text string.

The buttons that you see are empty masked subsystems. If you select one of the blocks and then select "Look Under Mask" from the Simulink "Edit" menu, you will observe that the subsystem is empty. However, each block has a callback function that executes under specific conditions. For instance, the OpenFcn callback function executes when a user double-clicks the block. In this example, when a user double-clicks the "Action 1" block, the OpenFcn callback executes and displays the text "Perform Action 1". Similarly, when a user double-clicks the "Open VDP model" block, the OpenFcn callback executes and opens the VDP demo model.

MATLAB: Callback Function of uimenu

when uimenu (undo redo) callback goes to undo or redo functions, the parent of the hObject is uimenu and not the figure itself. The parent of uimenu is figure. which means if you want to call figure, you have to write

hObject.Parent.Parent

so when you call

entries=hObject.Parent.UserData;

for uimenu, the parent is uimenu and not the figure while for buttons of redo and undo the parent is figure itself

the best option is change

hObject.Parent

with

handle

in your code
