I'm now using R2017a, and code that used to work with anchorToBottom is no longer working... any ideas?

>> str = {'multi','line','editbox'};
>> hEdit = uicontrol('style','edit','max',3,'string',str);
>> jhEdit = findjobj(hEdit)
jhEdit =
    1×0 empty handle

Hello,
This seems to work fine for editbox, but how can this be extended to a cell of uitable?
My specific problem is: I have a hint text on a specific editable (text) cell of a table. When I click this cell I want the text to disappear but still I want the cursor to be in the cell to introduce the new value. I have done the first part, but to be able to write on this cell I need to click again, and it would be good if I didn’t have to do it.
Thank you very much in advance,
Ana

In reply to Yair Altman. Thanks Yair, the EDT mixup page was helpful. Managed to get my GUI working as I wanted it to.

In reply to Tiago Silva. @Tiago - I believe that this is another case of EDT mixup.

Hello Yair, I'm trying to use something similar to this in order to remember the position of a uitable scrollbar after a data update. My problem is that although I got it work, it only really works in debug mode. The gui I'm developing is fairly complicated, but even a simple example code like the following only works as I'd expect it to do in debug mode:

h = uitable;
set(h,'Data',rand(20));
pause(1);
jh = findjobj(h);
jhScroll = jh.getVerticalScrollBar;
position = 100;
set(h,'Data',rand(20));
jhScroll.setValue(position);

When running this with breakpoints and stepping each line at a time I end up with the uitable updated and the scrollbar at the bottom, as I expected it to behave. Executing the code normally, I can see the uitable is updated but I end up with the scrollbar at the top. Any idea of what I might be doing wrong? Thanks in advance.

In reply to Thomas. @Thomas, perhaps this is done when the control is still not visible, perhaps you're modifying the control in Matlab later on (this resets the underlying component), perhaps something else. You'll need to debug it step-by-step to see where the problem is.

Hi Yair, I have a multi-line editbox with a scrollbar (vertical as needed) and I want it, when activted, to be always on the botton. I tryed this

 
jVScroll = jScrollPane.getVerticalScrollBar;
jVScroll.setValue(jVScroll.getMaximum);
jScrollPane.repaint;

and this

 
jhEdit = findjobj(handles.my_editbox);
jhEdit.anchorToBottom;

but didn't work... Can you tell me what am I doing wrong? Thanks

Using another one of Yair's suggestions worked better for me:

 
jhEdit = findjobj(handles.status_text);
jhEdit.anchorToBottom;

In reply to Johannes.

Johannes,

Similar to you, I’m adding a console/log window to a GUI and would like the scroll bar at the bottom. With a list box, were you able to get rid of the ‘jump’ problem altogether?

I think there might be a solution using an edit box by diving deeper into the underlying Java. However, I have only recently started using the findjobj utility, so I could be wrong about that.
