Stephane,
Try an XmNenterCellCallback that looks something like this
----------%<---------------------------------------->%-----------
void
cellEnteredCB(Widget w, XtPointer clientData, XtPointer callData)
{
XbaeMatrixEnterCellCallbackStruct* cbs =
(XbaeMatrixEnterCellCallbackStruct*) callData;
// Decide if the cell should be editable ...
Boolean editable = cell_should_be_editable(cbs->row, cbs->column);
// Set the callback structs fields so that editing does not proceed
// and the text widget is not mapped if the cel is not editable.
cbs->doit = cbs->map = editable;
}
----------%<---------------------------------------->%-----------
Have Fun,
jostle.

Xbae
There's an XmNenterCellCallback in XbaeMatrix which allows you do perform
actions before entering a cell. Here's what the manual page says about it :
Specifies a list of callbacks to be called immediately before a cell
is to be edited. This callback list is called by the EditCell() action.
A pointer to an XbaeMatrixEnterCellCallbackStruct is passed to the
callbacks. The application can specify the editability of specific cells
using this callback list as well as specifying configuration options
for the XmText.
Sounds like what you need, doesn't it ?
