Re: how to type text on canvas selection after icon bar

There are several ways, from doing everything in canvas (perhaps there are UI libraries for the canvas, or manage key strokes and corresponding display) to overlaying an HTML input text box over the canvas to get the text input with all the power of the browser's native control. -- Philippe Lhoste -- (near) Paris -- France -- http://Phi.Lho.free.fr -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

In GWT, ListHandlerListString columnSortHandler does not sort properly
I got these code:
ListHandlerListString columnSortHandler = new ListHandlerListString(
list);
columnSortHandler.setComparator(nameColumn,
new ComparatorListString() {
public int compare(ListString o1, ListString o2) {
if (o1 == o2) {
return 0;
}
// Compare the name columns.
if (o1 != null) {
return (o2 != null) ? o1.get(0).compareTo(o2.get(0))
: 1;
}
return -1;
}
});
table.addColumnSortHandler(columnSortHandler);
When sorting column contains iPhone 1, iPhone 2, iPhone 3... then it sorts
correctly ie, iPhone 1, iPhone 2, iPhone 3 for ascending iPhone 3, iPhone 2,
iPhone 1 for decending
But when sorting column contains:
1.92 MP
3.15 MP AF 0.31 MP
3.2 MP
5 MP AF and flash
1.3 MP
1.3 MP
2 MP (rear); 0.3 MP (front)
1.92 MP AF with flash (rear)
it follows no correct order, it didn't even put the 2 1.3 MP cell next to
each other. The correct order for the above list should be:
1.3 MP
1.3 MP
1.92 MP
1.92 MP AF with flash (rear)
2 MP (rear); 0.3 MP (front)
3.15 MP AF 0.31 MP
3.2 MP
5 MP AF and flash
Is there anything wrong with the code above?

Today I noticed that the output of my NumberFormat (GWT 2.5.0) is not what

it had been set to. So I played with it a little and found the output to

The formats:
1: NumberFormat.getFormat(#,###.##)
2: NumberFormat.getFormat(#,###.00)
3: NumberFormat.getFormat(#,##0.00)
The output is as follows:
1: 3.57, 0.98, 0.6
2: 3.57, .98, .60
3: 3.57, 0.98, 0.60
The NumberFormat class doc states the following:
0 Number Yes Digit
# Number Yes Digit, zero shows as absent
According to the doc comments, show above, I was expect the following
output for each
format:
1: 3.57, .98, .6
2: 3.57, .98, .60
3: 3.57, 0.98, 0.60
What going on here? The output for 1 should not have the leading 0, just
like the
2nd format.
The zero shows as absent indication is terse and vague... We can suppose it is about
non-significant zeroes, but it is better if explicitly stated!
Just note that Java's DecimalFormat just acts the same:
DecimalFormat[] nfs =
{
new DecimalFormat(#,###.##),
new DecimalFormat(#,###.00),
new DecimalFormat(#,##0.00)
};
double[] vals = { 3.57, 0.98, 0.6 };
for (DecimalFormat nf : nfs)
for (double v : vals)
System.out.println(nf.format(v));
==
3,57
0,98
0,6
3,57
,98
,60
3,57
0,98
0,60
(French locale!)
I am not sure how to interpret that when reading the JavaDoc...

I did that for a numerical comparison of values with units, for example:
@Override

String v1 = o1.get(columnIndex);
String v2 = o2.get(columnIndex);
double d1 = DataService.parseValue(v1);

The DataService.parseValue() parses the double at the start of the string, stopping on the
unit symbol.
The columnIndex is a member of my Comparator, since we do the same sorting for
all columns.

Re: IE10 support in Gwt
It does but out of curiosity, if I add IE10 permutation/browser detection to UserAgent.gwt.xml to which value should I set the property-fallback? I mean is property fallback-recursive (I would assume it is) so setting it to IE9 should work? In case IE9 rule isn't specified it will recursively fallback to IE8 (and generate a compiler warning) right?

Re: FormPanel.SubmitEvent cancel not working

Re: In GWT, ListHandlerListString columnSortHandler does not sort properly
Your code didn't work, beside it got the problem for non-digit string. Ex:
if i sort this list:
Full slide-out QWERTY
Full QWERTY
Full QWERTY
Numeric with T9 multimedia
Soft QWERTY
Slide-out QWERTY
Full QWERTY
Full QWERTY
Slide-out QWERTY
It still didn't show the correct result.
Note: for this table, I have to add the columns dynamically, so i use
ListString for column, not just String.

requests, I'm not sure if it's a thing in my code or not:
Here is a sample of the requests:
http://gdata.youtube.com/feeds/api/videos/02HCaj9h8Lo?v=2alt=jsoncallback=__gwt_jsonp__.P8.onSuccess
http://gdata.youtube.com/feeds/api/videos/02HCaj9h8Lo?v=2alt=jsoncallback=__gwt_jsonp__.P7.onSuccess
http://gdata.youtube.com/feeds/api/videos/02HCaj9h8Lo?v=2alt=jsoncallback=__gwt_jsonp__.P6.onSuccess
All with the same exact content!
This is my code for the jsonprequest builder:
public void getVideo(final String url,
final AsyncCallbackYoutubeVideoData async) {
String reqUrl;
reqUrl = http://gdata.youtube.com/feeds/api/videos/; + id +
?v=2alt=json;
requestBuilder.requestObject(URL.encode(reqUrl),
new AsyncCallbackYoutubeVideoData() {
public void onFailure(Throwable caught) {
async.onFailure(caught);
}
public void onSuccess(YoutubeVideoData result) {
async.onSuccess(result);
}
});
}
Also, I'm getting this error for including a frame of a different domain:
Unsafe JavaScript attempt to access frame with URL

frame with URL
http://www.youtube.com/embed/02HCaj9h8Lo?wmode=transparentrel=0autohide=1showinfo=0.
Domains, protocols and ports must match.
I included this in my module file, but it didn't help:

Re: In GWT, ListHandlerListString columnSortHandler does not sort properly
i forgot to tell , the columns were iritated in a loop.
ListHandlerListString columnSortHandler = new ListHandlerListString(
list);
for (int k=0; k10; k++){
IndexedColumn myColumn=new IndexedColumn(k+1);
table.addColumn(myColumn, col +k);
myColumn.setSortable(true);
columnSortHandler.setComparator(myColumn,
new ComparatorListString() {
public int compare(ListString o1, ListString o2) {
return o1.get(0).compareTo(o2.get(0));
}
});
}
When I do the sorting, the sorting action was invoked, the table did the
sorting but the orders of values in that column is not correct. So I suspect it
could be I put the columnSortHandler.setComparator inside a loop that causing
the problem.
How to fix it?

Which one? The numerical comparison was shown only to illustrate how to do
a non-trivial sort.
The first one was to show you complicated too much the comparison method,
it can be much
simpler.
Note that your method as well as mine only sort the first column of the
table.
As shown in the second method, if you plan to sort another column, you
have to provide its
index to get the data at the proper place.

Re: In GWT, ListHandlerListString columnSortHandler does not sort properly
So you always sort on the first field whichever the column header being
clicked?

Re: In GWT, ListHandlerListString columnSortHandler does not sort properly
Someone from other forum solved it. So simple!
public int compare(ListString o1, ListString o2) {
if (o1 == o2) {
return 0;
}
// Compare the column.
if (o1 != null) {
int index = verbColumn.getIndex();
return (o2 != null) ?
o1.get(index).compareTo(o2.get(index)) : 1;
}
return -1;
}
But thax you all you guy anyway.

When sorting column contains iPhone 1, iPhone 2, iPhone 3... then it sorts
correctly ie, iPhone 1, iPhone 2, iPhone 3 for ascending iPhone 3, iPhone
2, iPhone 1 for decending
But when sorting column contains:
1.92 MP
3.15 MP AF 0.31 MP
3.2 MP
5 MP AF and flash
1.3 MP
1.3 MP
2 MP (rear); 0.3 MP (front)
1.92 MP AF with flash (rear)
it follows no correct order, it didn't even put the 2 1.3 MP cell next
to each other. The correct order for the above list should be:
1.3 MP
1.3 MP
1.92 MP
1.92 MP AF with flash (rear)
2 MP (rear); 0.3 MP (front)
3.15 MP AF 0.31 MP
3.2 MP
5 MP AF and flash
Is there anything wrong with the code above?
