Re: [platform-swt-dev] Table fullsize + first ToolItem always enabled

[Carolyn MacLeod <Carolyn_MacLeod@xxxxxxxxxx>]

In order for your Table to be "big",
you need to set its layout data to "fill" and "grab",
perhaps something like the following:
table.setLayoutData(new GridData(GridData.FILL_BOTH));

This article on Layouts in SWT may be
useful:
http://www.eclipse.org/articles/Understanding%20Layouts/Understanding%20Layouts.htm

I don't understand what you mean when
you say your push button tool is enabled - perhaps you mean that it has
focus?
(Use the keyboard arrow keys or tab
to see that the widget that has focus is drawn differently).
Widgets are always enabled when they
are created. To disable a widget, you need to send it setEnabled(false),
but I don't think this is what you mean.

In future, please ask user questions
on the SWT newsgroup.
Perhaps this link might have some useful
info for you - it is the SWT "Getting Started" page, and it will
tell you how to get to the newsgroup:
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform-swt-home/SWT_Resources.html

Good luck, and welcome to SWT!

Subject	[platform-swt-dev] Table fullsize + first ToolItem always enabled

Hello list,

I'm having a problem with the Table class: it isn't shown in fullsize.
I've searched through the archive of this list, but I couldn't find any
usefull answer so far.

I think the best way to describe the error is by showing a screenshot:
http://www.clueless.be/Pics/swt-table.jpg. Below is my code:

import org.eclipse.swt.widgets.*;
import org.eclipse.swt.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.graphics.*;

public class Test {
                
public static void main(String args[]) {
                
                 Display
display = new Display();

                
                 Shell
shell = new Shell(display);
                
                 shell.setMaximized(true);
                
                 shell.setText("Planner");

                
                 GridLayout
gridLayout = new GridLayout();
                
                 gridLayout.verticalSpacing
= 0;
                
                 gridLayout.marginWidth
= 0;
                
                 gridLayout.marginHeight
= 0;
                
                 gridLayout.horizontalSpacing
= 0;
                
                 shell.setLayout(gridLayout);

                 CoolBar
coolBar = new CoolBar(shell, SWT.NONE);
                
                 coolBar.setLayoutData(new
GridData());

                
                 ToolBar
toolBar = new ToolBar(coolBar, SWT.FLAT);

                
                 toolItem
= new ToolItem(toolBar, SWT.PUSH);
                
                 toolItem.setText("New

                 toolItem.setToolTipText("New

                 toolItem
= new ToolItem(toolBar, SWT.PUSH);
                
                 toolItem.setText("Save

                 toolItem.setToolTipText("Save

                 toolItem

                 toolItem.setText("Open
Saved Route");
                
                 toolItem.setToolTipText("Open

                 CoolItem
coolItem = new CoolItem(coolBar, SWT.NULL);
                
                 coolItem.setControl(toolBar);

                
                 Point
size = toolBar.computeSize(SWT.DEFAULT, SWT.DEFAULT);
                
                 Point
coolSize = coolItem.computeSize(size.x, size.y);
                
                 coolItem.setSize(coolSize);

                
                 //

                 Table
table = new Table(shell, SWT.SINGLE);
                
                 table.setHeaderVisible(true);
                
                 table.setLinesVisible(true);
                
                 
                
                 TableColumn
tableColumn = null;
                
                 
                
                 tableColumn
= new TableColumn(table, SWT.LEFT);
                
                 tableColumn.setText("Step");
                
                 tableColumn.setWidth(40);

                
                 tableColumn
= new TableColumn(table, SWT.LEFT);
                
                 tableColumn.setText("Description");
                
                 tableColumn.setWidth(80);
                
                 
                
                 tableColumn
= new TableColumn(table, SWT.LEFT);
                
                 tableColumn.setText("Distance");
                
                 tableColumn.setWidth(80);
                
                 
                
                 tableColumn
= new TableColumn(table, SWT.LEFT);
                
                 tableColumn.setText("Time");
                
                 tableColumn.setWidth(80);

                
                 TableItem
item1 = new TableItem(table, 0);
                
                 item1.setText(new
String[] { "a", "b" });
                
                 ...

                
                 //
------------------

                
                 shell.pack();
                
                 shell.open();

                
                 while
(!shell.isDisposed()) {
                
                 
               
if (!display.readAndDispatch())
                
                 
               
                 display.sleep();
                
                 }

                
                 display.dispose();
                
}
}

And what is the reason the first ToolItem (the button with 'New Route'
in this case) always being enabled?

I'm still new to SWT programming, so please keep it simple ;)

Thanks a lot for your time!
