[codenameone-discussions] Re: scrollRectToVisible Table component not behaving

[Shai Almog]

scrollRectToVisible would work if the rectangle was there. The main problem 
is that the table is rebuilt from scratch every time you use set model. 
In this thread I explained the right solution to your problem:

Table is written on top of Table layout, you can just recreate the layout 
and apply it again. 
See the code of Table: 
https://github.com/codenameone/CodenameOne/blob/master/CodenameOne/src/com/codename1/ui/table/Table.java#L214-L224

FYI you can debug directly into the Codename One sources to get insight 
into how things work. This post is a bit old but most of this still works 
as is:

[Shai Almog]

We'll try to verify the fix again. Which OS/Java version are you using?

[codenameone-discussions] scrollRectToVisible Table component not behaving

[shop . service . assistant]

If you are experiencing an issue please mention the full platform your 
issue applies to:
IDE: NetBeans/Eclipse/IDEA NetBeans 8.2
Desktop OS Windows 10 Pro
Simulator Latest
Device PC, Android, IOS

Have a simple table that a Button Action Event calls the following code.

Rectangle rect = table.getSelectedRect();
table.scrollRectToVisible(rect.getX(), 
rect.getY(), rect.getWidth(), rect.getHeight(), this);

The Table contains 60+ rows.

Scroll Down and click to select row say 60
Then click the Button to force a scroll and the Page scrolls to the top 
where 1/2 the top page is blank

See attached pic

In general, I use scrollRectToVisible when the user adds a new row in a 
large list, we want to scroll to the bottom for example.

Regards.

Thanks, I'm not pushing you to make any changes more over just to make sure 
I am not overlooking another package that may exist that will be more 
feature rich.
I appreciate your support and do not want to jeopardize same.

>From what I have read, the TableLayout 
 
class is fixed in size and can not be altered (add/delete rows dynamically) 
like Table can.

If this is the case, I think it best for us to continue to work with Table.

Thanks for all your support.

Regards.
