How do I programmatically set the size of the the web browser window that is created with the MATLAB web command " web " ?

I would like to use MATLAB's built-in web capabiliies to open a web page and place it on my screen in a specific location.

For example, when I enter the command:

[h1,h2,h3]=web('http://news.google.com','-notoolbar','-new'); % open a web page

I am able to determine the location of the web page on my screen:

    webPageScreenInfo = ([h2.getLocationOnScreen.x, ...
                          h2.getLocationOnScreen.y, ...
                          h2.getSize.width, ...
                          h2.getSize.height]);

I have only been able to get the location but not to set the location.

And my available screen size is given by:

availableScreenSize = get( groot, 'Screensize' ); % determine size of my screen

I have played with some undocumented stuff in MATLAB by exploring these commands and a few others:

  methodsview('com.mathworks.mde.webbrowser.WebBrowser')
  com.mathworks.mlservices.MatlabDesktopServices.getDesktop.closeGroup('Web Browser')

I am lost on how to proceed. Please help!

Note: undocumented/unsupported:

[h1,h2,h3] = web('http://news.google.com','-notoolbar','-new'); % open a web page
drawnow; pause(0.05);
jWindow = h2.getTopLevelAncestor;
jWindow.setSize(java.awt.Dimension(800,400));  % width,height
jWindow.setLocation(java.awt.Point(300,500));  % x,y

Note that the x,y location is the pixel-position of the window's top-left corner, downward & rightward of the top-left monitor corner (unlike Matlab which measures upward from bottom-left, Java measures downward from top-left).

Thanks Yair.

I incorporated the code snippit that you suggested. However, I get the following error shown in bold print::

Dot indexing is not supported for variables of this type

when my very short program encounters the script command you suggested:

jWindow.setSize(java.awt.Dimension(800,400)); % width,height

Note that the jWindow object is empty after the command

jWindow = h2.getTopLevelAncestor

I am running MATLAB 2018B.

thanks

You need to let the new window fully render before retrieving its window handle. You do this with a drawnow and/or pause command. I edited my answer above to reflect this. You can modify the pause duration [or perhaps even eliminate the pause altogether) to suit your specific platform.
