Re: [platform-swt-dev] TABLE REFRESH PROBLEM

Hi,

What is the reason you are using so many TableEditors? Can't you use JFace-Viewers which makes Tables/Trees editable with only one TableEditor?

Any solution???

I try usyng a row layout on a composite as a table.
Inside this composite i add another composite with three composite as
item colunms inside it so i will hava a row for the table.
adding more row i have a table but when i scroll i see the same
problem .
I do this.

Composite table = new Composite(shell,0);
table.setLayout(new RowLayout(SWT.VERTICAL));

GridLayout layout = new GridLayout();
layout..numColumns = 3;

Composite row1 = new Composite(table);
row1.setLayout(layout);
Composite row2 = new Composite(table);
row2.setLayout(layout);
Composite row3 = new Composite(table);
row3.setLayout(layout);

Text row1_item1 = new Text(row1);
Text row1_item2 = new Text(row1);
Text row1_item3 = new Text(row1);


This works as a table but the scroll does not work as in the image.


i attach 2 png image before and after i scroll the table. Regards, Michele

While you are scrolling the items are not visible but when you stop
scrolling are the items visible again?
