How do I set first column width on GWT CellBrowser - gwt

Question

There is a bug preventing the setting of the first column width of the CellBrowser widget. There is also a workaround, explained here
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/4fc39b5805833ea2
Apparently it works, but can anybody explain how to subclass the CellBrowser to make it work? Please show me some code.

Answer 1

CellBrowser cellBrowser = new CellBrowser(model, null) {
// HACK: workaround for setDefaultColumnWidth not setting the width of the first column!
// SEE: https://groups.google.com/forum/?pli=1#!topic/google-web-toolkit/T8Ob...
public void setDefaultColumnWidth(int width) {
super.setDefaultColumnWidth(width);
SplitLayoutPanel splitPanel = (SplitLayoutPanel) getWidget();
splitPanel.setWidgetSize(splitPanel.getWidget(0), width);
}
};
cellBrowser.setDefaultColumnWidth(300);
from the thread linked to in the question: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/4fc39b5805833ea2
If you wanted a re-usable class with this fix in (which would probably be a good idea), it's simple enough to convert this anonymous subclass into a regular subclass:
public class FixedCellBrowser<T> extends CellBrowser<T> {
public FixedCellBrowser(TreeViewModel model, T root) {
super(model, root);
}
public void setDefaultColumnWidth(int width) {
super.setDefaultColumnWidth(width);
SplitLayoutPanel splitPanel = (SplitLayoutPanel) getWidget();
splitPanel.setWidgetSize(splitPanel.getWidget(0), width);
}
}
(Note: I have not tried compiling this code.)
