Let me get this straight, you run the code in dev mode, you set the
endTime TextInputCell to a value, let's say 14:18 and on pushing Enter
or leaving focus, the code parses the value and updates it to 15:19
(as the + 1 is set in the FieldUpdater) and then this displays
immediately on your machine??
Yes.
In fact, there are other actions that can occur after pressing enter.
For example, the user could choose to delete a row in the table.
You can review the code at http://code.google.com/p/gwt-sked, or try
out the project at http://jchimene.com/sked.html The specific example
you cite can be demonstrated by the following actions:
0) Select "Load sample schedule" under the "Help"menu"
1) Click a cell in the "Likely" column for a specific activity
2) Set the value to zero. Press enter to blur the cell. Notice the
adjacent cell values are set to zero.
3) Enter a non-zero value in the "Likely" cell. Press Enter to blur
the cell, the other cells are immediately updated.
I'm happy to supply annotations or answer questions.
You might have already done this, but try compiling the code in
PRETTY mode and run it using a browser that will display the
Javascript console (I usually use Firefox + Firebug). See if you have
any "interesting" runtime errors.
Thinking further on your question, it occurs to me that you're asking:
"how do I update THE SAME CELL". I have to admit this caused some
consternation. For a while, I considered sub-classing EditTextCell, an
approach I abandoned as unworkable.
The Predecessor column implements this same cell update behavior to
correct data entry errors that might introduce a network cycle. The
apropos code is in "ActivityPresenter.onPredecessorChange()"
Demonstrate as follows:
0) Select "Load sample schedule" under the "Help"menu"
1) Click a cell in the "Predecessor" column for a specific activity
2) Enter a comma-separated list that includes that row's ID. For
example, if you choose activity "C",enter the string "1,3" as that
activity's predecessor list. Press enter to blur the cell. Notice that
the string ",3" is removed from the value.
The action sequence is:
0) Update the Data Provider list:
dataProvider.setList(new ArrayList<Activity>(scheduler.getValues()));
dataProvider.flush(); //Maybe not needed?
1) Update the view
cellTable.setRowData(list);
cellTable.redraw();
