Dani – You can use jViewport.setViewPosition(java.awt.Point(0,0)) as I showed in earlier comments here

@Peter – you can modify the scrollbars by accessing them directly. For example:

% Create a multi-line (Max>1) editbox uicontrol
hEditbox = uicontrol('style','edit', 'max',5, ...);
% Get the Java scroll-pane container reference
jScrollPane = findjobj(hEditbox);
% Update the scrollbar handles
jSize = java.awt.Dimension(40,40);
jScrollPane.getHorizontalScrollBar.setPreferredSize(jSize);
jScrollPane.getVerticalScrollBar.setPreferredSize(jSize);
% Repaint the scrollpane on-screen
jScrollPane.revalidate

A more advanced solution could be to modify Matlab’s default Look-&-Feel (javax.swing.UIManager.put('ScrollBar.width',40);) so that all scrollbars created from now on (in the current Matlab session) will have a width of 40 pixels.

I’m trying scroll to a specific position in a GUI table. But when I load the value an exception appears.

I do this, it’s okay?

jTable = findjobj(handles.ranking); %% Ranking is a GUI table
jScrollPane = jTable.getComponent(0);
scrollPos = jScrollPane.getViewPosition;
set(jScrollPane,'ViewPosition',[0,69]); %% for exaple, x = 0, y = 69 position.

The error is this,

I am using Matlab 2009a

By using findjobj and the table’s setValueAt() method. The specifics depend on your Matlab release. Read my uitable customization report or section 4.1 in my Matlab-Java programming book for details.

“By updating the cell at the Java level rather than updating the uitable’s Data property”

How do you do that?

I guess that my manipulation of the rowHeader by attaching a textarea, destroys everything. 🙁 Before manipulation my object has Wrapping off. After manipulation there is no Wrapping anymore, neither on or off.. it’s like it’s an another object

Hello,
unfortunately it’s not true. I just tried by opening my programm directly with smaller figure width. I did not resize it after. The text is immediately wrapped :-/ I think that setWrapping doesn’t work as it should.
