My problem is: after clicking on brushing tool, I select data by dragging over the data-points. Now, when I right click it gives me a 5 to 6 options: remove data, replace with , delete create variables etc. Can I customize these options and create callbacks for these options? because I don’t want all these options in my objective.

with regards,

@klimmbimm – adding simple buttons to the figure toolbar can be done using the uipushtool function

@Andi – Of course you can modify the main Matlab desktop toolbar, just like a figure toolbar. Here is one way to get a reference to the toolbar container, which is a standard com.mathworks.mwswing.MJToolBar object:

hMainFrame = com.mathworks.mde.desk.MLDesktop.getInstance.getMainFrame;
hToolbar = hMainFrame.getContentPane.getComponent(0).getComponent(0);

You may of need to adapt the code for docking etc., but this should be enough to get you started.

Is there a way of performing these sort of modifications on the main Matlab toolbar rather than on figure toolbars.

Thanks for your help

@lux – there is no official way to do this, but of course (as always) there’s a back-door: you can simply add your code to the printdlg.m file. This will get executed whenever the user tries to print any figure.

In Matlab releases up to R2009b you can add your code to the built-in figureToolbarCreateFcn.m function. Unfortunately, this back-door was closed in R2010a onward…

You should also take a look at http://undocumentedmatlab.com/blog/customizing-print-setup/, which explains how to programmatically modify the default print setup.
