my goal is to display a Table through parsing an XML file.
I'm using a SAX Parser and the content has multirows and I want the table width to fit to the display. Of course Y_AXIS scrolling would be ok.
Right now, I'm using the HTMLTableModel of src/com/sun/lwuit/html/ and it's corresponding HTMLTable. For this I declared it's methods public so I can access them. This works fine so far. This allows me to declare tables without knowing their size prematurely.
To allow multirows, I'm embedding TextAreas in the Cells.
Now the problem: The HTMLTable t needs t.setScrollableY(true), or else not all rows are shown.
This causes the table to be a bit to large in X direction, so the right border isn't shown. Also the bottom border isn't shown all the time.
The container in which the table is embedded has BorderLayout.Y_AXIS.
Things I tried:
t.setPreferredW(mainContainer.getLayoutWidth()); This does reduce the size of the table, but then the table doesn't show all it's rows, like without t.setScrollableY(true).
t.setLayout(new BoxLayout(BoxLayout.Y_AXIS)) this causes an java/lang/ClassCastException.
Any ideas? Thanks in advance.
Excerpt from my code:
} else if (qName.equalsIgnoreCase("td")) {
if (sb.length() > 0) {
String sbt = new String(sb);
sb.delete(0, sb.length());
TextArea c = new TextArea(sbt);
c.setEditable(false);
c.getStyle().setFont(smallFont);
table.addCell(c, false, null);
}
} else if (qName.equalsIgnoreCase("tr")) {
debugPrint("Row closed.");
table.commitRow();
} else if (qName.equalsIgnoreCase("table")) {
HTMLTable t = new HTMLTable(table);
//without scrollable Y not all table rows are shown
t.setScrollableY(true);
//t.setPreferredW(screenWidth);
//this is verboten.
t.setLayout(new BoxLayout(BoxLayout.Y_AXIS));
mainContainer.addComponent(t);
tableBool = false;

You can't change the layout of the table from table layout otherwise it will not be a table.
It should be possible to get the table to fill the width of a parent BoxLayout_Y by assigning width percentages to table columns up to 100% e.g. for a 3 column table return assign 33, 33 & 44.
This can be achieved by subclassing table and overriding the method:
protected TableLayout.Constraint createCellConstraint(Object value, int row, int column) {
TableLayout.Constraint c = super.createCellConstraint(value, row, column);
c.setWidthPercentage(whateverYouWant);
return c;
}
