hi,
i want layout my ui following:
on the left upper edge there is a text, on the right uper edge there are
two buttons and in the second row all the horizontal and vertical space
will be given to a table!
this is my code:
public void createPartControl(Composite parent) {
parent.setBackground(new Color(parent.getDisplay(), 255, 255, 255));
parent.setLayout(new GridLayout(4, false));
Label textLabel = new Label(parent, SWT.NONE);
textLabel.setBackground(parent.getBackground());
textLabel.setForeground(new Color(textLabel.getDisplay(), 195, 209,
224));
textLabel.setFont(new Font(textLabel.getDisplay(), "", 14, SWT.BOLD));
textLabel.setText(this.getLeadingFilename() + " ResourceBundle");
Canvas spacer = new Canvas(parent, SWT.NONE);
//spacer.setBackground(parent.getBackground());
Button addLineButton = new Button(parent, SWT.NONE);
addLineButton.setBackground(parent.getBackground());
addLineButton.setImage(Util.createImage("icons/addRow.gif"));
Button removeLineButton = new Button(parent, SWT.NONE);
removeLineButton.setBackground(parent.getBackground());
removeLineButton.setImage(Util.createImage("icons/deleteRow.gif "));
TableViewer tableViewer = new TableViewer(parent, SWT.SINGLE |
SWT.BORDER);
Table table = tableViewer.getTable();
TableColumn tableColumn = new TableColumn(table, SWT.LEFT | SWT.FILL);
tableColumn.setText("Key");
tableColumn = new TableColumn(table, SWT.LEFT | SWT.FILL);
tableColumn.setText("deutsch - Deutschland");
TableItem tableItem = new TableItem(table, SWT.LEFT, 0);
tableItem.setText(0, "w");
tableItem.setText(1, "a");
tableItem = new TableItem(table, SWT.LEFT, 1);
tableItem.setText(0, "x");
tableItem.setText(1, "b");
tableItem = new TableItem(table, SWT.LEFT, 2);
tableItem.setText(0, "y");
tableItem.setText(1, "c");
tableItem = new TableItem(table, SWT.LEFT, 3);
tableItem.setText(0, "z");
tableItem.setText(1, "d");
table.setHeaderVisible(true);
table.setLinesVisible(true);
GridData gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
textLabel.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, true, false);
spacer.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
addLineButton.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
removeLineButton.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.FILL, true, true, 4, 1);
removeLineButton.setLayoutData(gridData);
}
wheres the bug? what are my mistakes?
thank you!!!

1)
GridData gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
textLabel.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, true, false);
spacer.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
addLineButton.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
removeLineButton.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.FILL, true, true, 4, 1);
//removeLineButton.setLayoutData(gridData); //!!!! Oops - assigned data to
wrong widget
table.setLayoutData(gridData);
2)
In 3.1, the above code will work as you expect. In 3.0 however, GridLayout
has a funny habit of making the last column expandable when you span
multiple columns. So in 3.0 and 3.1 the following works:
GridData gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
textLabel.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, true, false);
spacer.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
addLineButton.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.TOP, false, false);
removeLineButton.setLayoutData(gridData);
gridData = new GridData(SWT.FILL, SWT.FILL, false, true, 4, 1); // Don't
grab horizontal here, the spacer is already achieving this for you
table.setLayoutData(gridData);
