Hi

I am converting a table to be a tree. I used the code below to set the
widths dynamically. Is there an equivalent way in Tree?

thanks

....

Table testTableView = testTableEditorViewer.getTable();
testTableView.clearAll();

int columnCount = testTableView.getColumnCount();
for (int tableColumnIndex = columnCount - 1; tableColumnIndex
>= 0; tableColumnIndex--) {
testTableView.getColumn(tableColumnIndex).dispose();
}

----> TableLayout tableLayout = new TableLayout();
----> int columWeight = 100 / testCaseTableColumnCount;
String[] columProperties = new String[testCaseTableColumnCount];
for (int columnIndex = 0; columnIndex <
testCaseTableColumnCount; columnIndex++) {
new TableColumn(testTableView, SWT.LEFT).setText(Integer
.toString(columnIndex));
----> tableLayout.addColumnData(new ColumnWeightData(columWeight,
true));
columProperties[columnIndex] = String.valueOf(columnIndex);
}

testTableEditorViewer.setColumnProperties(columProperties);

TestTableViewCellModifier testTableViewCellModifier = new
TestTableViewCellModifier(
this);
testTableEditorViewer.setCellModifier(testTableViewCellModif ier);
CellEditor[] celleditors = new
CellEditor[testCaseTableColumnCount];
for (int cellEditorIndex = 0; cellEditorIndex <
testCaseTableColumnCount; cellEditorIndex++) {
TextCellEditor textCellEditor = new
TextCellEditor(testTableView);;
celleditors[cellEditorIndex] = textCellEditor;
}

----> testTableView.setLayout(tableLayout);

....

Hi Hugo,

There isn't an equivalent TreeLayout class in jface, and since eclipse is
now api frozen for 3.1, there won't be one appearing. However I did a quick
experiment and found that I could create an equivalent TreeLayout class
simply by making a copy of TableLayout and changing "Table" to "Tree"
throughout. You should give this a try.

Hi Grant

I followed your suggestion and it works. I opened a bug with the code
for TreeLayout attached.

thanks
