Hi,
I'm writing SWT application, here is a screenshot:
http://public.fotki.com/akravets/life/random_stuff/clientsql .html
The problems I am having are marked in red. The widget are not starting
at 0,0 of the tab, I don't want to have gray space around my widgets (if
possible). Below the tab folder there is no blue border, however if I
start resizing the right sash, then the border appears. Here is a
screenshot of when border is visible:
http://public.fotki.com/akravets/life/random_stuff/clientsql 2.html
I appreciate any help. Here is the layout code:
Label resultLabel = new Label(this, SWT.LEFT | SWT.BORDER);
table = new Table(this, SWT.BORDER | SWT.MULTI |
SWT.FULL_SELECTION | SWT.VIRTUAL);
final GridData gd = new GridData(GridData.FILL_BOTH);
table.setLayoutData(gd);
table.setHeaderVisible(true);
table.setLinesVisible(true);
setLayout(new GridLayout(1,true));
GridData labelData = new GridData(GridData.FILL_HORIZONTAL);
resultLabel.setLayoutData(labelData);
GridData resultData = new GridData(GridData.FILL_BOTH);
table.setLayoutData(resultData);

GridLayout has a defualt margin all around of 5 pixels. You can override
this as follows:
GridLayout layout= new GridLayout(1,true);
layout.marginWidth = layout.marginHeight = 0;
setLayout(layout);

Not quite sure how you are missing part of the blue border - is "this" a
child of CTabFolder?

I am not sure what do you mean by child of CTabFolder. It's a CTabItem,
and the top border is there, only it's visible when I make my sash
wider. If you look at first screenshot, you'll see what I mean.

When you create a widget to be displayed inside a CTabItem, it is created
as a child of the CTabFolder and then associated with the CTabItem using
CTabItem.setControl(). For example :
CTabFolder folder = new CTabFolder(shell, SWT.BORDER);
CTabItem item = new CTabItem(folder, SWT.CLOSE);
item.setText("Item "+i);
item.setImage(image);
Text text = new Text(folder, SWT.MULTI | SWT.V_SCROLL | SWT.H_SCROLL);
text.setText("Text for item "+i+"\n\none, two, three\n\nabcdefghijklmnop");
item.setControl(text);
In your code snippet below, is "this" a subclass of Composite and do you
call setControl() on the CTabItem with "this"?

Yes, "this" is a Class that extends Composite, and in the calling class
I setControl thru this Class.
