@Yogesh – You can do this anywhere in your Matlab session, or at the beginning of the function. Note that the relevant condition was modified by Anonymous (see the comments above) to:

str.indexOf('com.mathworks.mwswing.desk.DTSelectionManager') >= 0 || ...
str.indexOf('javax.swing.plaf.basic.BasicLookAndFeel') >= 0 || ...
str.indexOf('com.mathworks.widgets.text.mcode.MLintDecorator') >= 0

Yair/Anonymous,

Where do I insert the following lines to remove the bug with R2008+?

t=java.awt.Toolkit.getDefaultToolkit()
ev=t.getAWTEventListeners()
for i=1:length(ev)
    str=ev(i).getListener().getClass.toString
    if str.indexOf('com.mathworks.mwswing.desk.DTSelectionManager')>=0 || ...
       str.indexOf('javax.swing.plaf.basic.BasicLookAndFeel')>=0
        t.removeAWTEventListener(ev(i))
    end
end

Update, here’s an ugly hack I’ve inserted into uisplitpane so that a uitree correctly resizes if it’s in one of the panes.

In the updateSubPaneSizes, line 800, I’ve inserted:

%Z
hParent = get(hDivider,'ContainerParentHandle');
tree_handle = findobj(hParent,'UserData','com.mathworks.hg.peer.UITreePeer');
if(~isempty(tree_handle))
   pixelPos = getPixelPos(hDivider);
   set(tree_handle,'Units','pixels')
   current_tree_pos = get(tree_handle,'Position');
   set(tree_handle,'Position',[current_tree_pos(1) current_tree_pos(2) pixelPos(1)-2 pixelPos(4)]);
   drawnow;
end

Seems to work well enough.

Thanks,
Zach

This works great – one question I have though, I’m not able to get a uitree to resize when placed in one of the panes this creates:

fig_handle = figure;
[tree_pane,split_pane,hDiv] = uisplitpane(fig_handle,'Orientation','horizontal','DividerLocation',0.3,'DividerColor',[0.6 0.6 0.6]);
[top_pane,bottom_pane,vDiv] = uisplitpane(split_pane,'Orientation','vertical','DividerLocation',0.5,'DividerColor',[0.6 0.6 0.6]);
 
root_node = uitreenode('Test','Test', [], 0);
Tree = uitree('v0','Parent',tree_pane,'Root',root_node);
set(Tree,'Units',get(tree_pane,'Units'));
size_pane = get(tree_pane,'Position');
set(Tree,'Position',[0 0 size_pane(3) size_pane(4)]);

When the sliders are moved, the uitree doesn’t change size with the pane.

Please replace with this condition:

str.indexOf('com.mathworks.mwswing.desk.DTSelectionManager')>=0 || ...
str.indexOf('javax.swing.plaf.basic.BasicLookAndFeel')>=0 || ...
str.indexOf('com.mathworks.widgets.text.mcode.MLintDecorator')>=0

With these 3 event listeners removed, it seems no more exeptions occurs (hopefully).

This will solve the problems people have with R2008b and latter (exceptions…)

This also solve the exceptions with your brilliant Systray software.

Regards

t=java.awt.Toolkit.getDefaultToolkit()
ev=t.getAWTEventListeners()
for i=1:length(ev)
    str=ev(i).getListener().getClass.toString
    if str.indexOf('com.mathworks.mwswing.desk.DTSelectionManager')>=0 || ...
       str.indexOf('javax.swing.plaf.basic.BasicLookAndFeel')>=0
        t.removeAWTEventListener(ev(i))
    end
end

Wei - the standard javax.swing.JSlider doesn't have this out-of-the-box, but you can easily integrate 3rd-party components that do this. Google is your best friend, or search one of numerous Swing component repositories, like http://swing-components.safe-install.com/

Yair, This is nice. How easy to implement a round slider, like a meter?

@Mikhail – uisplitpane (or the split-panes concept, same as the tab-panes concept) is a component that can be embedded into any Matlab container or Layout Manager (Matlab itself has several layout managers – see the File Exchange), just like any other Matlab component/container. That was an important design point of uisplitpane. I agree that my sample screenshot would be more powerful if I showed the split-panes embedded in some Matlab uipanel – If I have some spare time I’ll do this.

Using the Java divider (as opposed to pure-Matlab button) enabled me to use its internal one-click flush hotspots (the arrows near the top/left end of the dividers that enable to flush the divider all the way to the side in one click) with a special mouse hover cursor. The property listeners were required to ensure that whenever the divider was modified, the split-panes did as well – this cannot be done in pure Matlab. The other undocumented functions had their own special reasons too.
