Hi,
I'm missing something basic, but can't seem to find out what. I have a
tableviewer in a multipage editor. I have added columns to the table
object, and they show up with proper headings.
My content provider returns a list of dom4j elements in the
getElements() method. The first column of data shows up perfectly. The
other three columns are blank. It seems that
myTableLabelProvider.getColumnText(Object element, int columnIndex)
is only getting called for the first (i.e. columnIndex==0) column. Where
/how do I set the column count?
BTW: I have successfully implemented several views with multi-column
tableviewers. Either I am having a senior moment, and forgetting some
critical step, or there is something special about putting a tableviewer
in a multipage editor?
Thanks
Sean

Hi, thanks for the reply. Below is my label provider code. This is part
of a sample plugin I hope to post on sourceforge which will show a few
techniques/solutions I had trouble with.
---------- CODE -----------------------
/**

*/
package com.stewthecat.kittyplug.views;
import org.apache.log4j.Logger;
import org.dom4j.Element;
import org.eclipse.jface.viewers.ITableLabelProvider;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.swt.graphics.Image;
import org.eclipse.ui.ISharedImages;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.ide.IDE.SharedImages;
public class KittyTableViewLabelProvider extends LabelProvider
implements ITableLabelProvider {
private final KittyTableView myView;
/**
* @param view
*/
KittyTableViewLabelProvider(KittyTableView view) {
myView = view;
}
private final Logger logger =
Logger.getLogger(KittyTableViewLabelProvider.class);
public String getColumnText(Object obj, int index) {
logger.debug("getColumnText(Object, int) - start");
// return getText(obj);
if (obj instanceof Element) {
Element node = (Element) obj;
String s = null;
switch (index) {
case KittyTableView.COL_PRIORITY:
s = node.attributeValue("priority");
return s == null ? "" : s;
case KittyTableView.COL_NAME:
s = node.attributeValue("name");
if (s == null) {
s = "n.a.";
}
return s;
case KittyTableView.COL_CATEGORY:
s = node.attributeValue("category");
return s == null ? "" : s;
case KittyTableView.COL_DUE:
s = node.attributeValue("due");
return s == null ? "n.a." : s;
default:
return "Unknown";
}
} else if (obj instanceof String[]) {
String l[] = (String[]) obj;
return l[index];
} else if (obj instanceof String) {
return (String) obj;
} else {
logger.warn("Object passed in was not a dom4j Element");
return "";
}
}
public Image getColumnImage(Object obj, int index) {
logger.debug("getColumnImage(Object, int) - start");
if (index == 0) {
return getPriorityImage(obj);
} else if (index == KittyTableView.COL_CATEGORY) {
return getCategoryImage(obj);
} else {
return null;
}
}
public Image getPriorityImage(Object obj) {
logger.debug("getImage(Object) - start");
ISharedImages shImages =
PlatformUI.getWorkbench().getSharedImages();
Image img = null;
if(obj instanceof String) {
Integer priority = new Integer((String)obj);
if(priority!=null) {
int p = priority.intValue();
if(p < 3) {
img =
shImages.getImage(ISharedImages.IMG_OBJS_BKMRK_TSK);
} else {
img = shImages.getImage(ISharedImages.IMG_OBJ_PROJECT);
}
} else {
img = shImages.getImage(ISharedImages.IMG_OBJ_ELEMENT);
}
}
return img;
}
public Image getCategoryImage(Object obj) {
logger.debug("getImage(Object) - start");
return
PlatformUI.getWorkbench().getSharedImages().getImage(IShared Images.IMG_OBJ_ELEMENT);
}
}
