Stopwatch Example
Dear GWT Group,
Is there code that already exists or do you have another suggestion in
formatting a seconds value into a stopwatch style string?
// Example call:
String stopwatch = buildStopwatch(350);
// returns 00:05:50
private String formatDigits(int s) {
if(s < 10) {
return "0" + Integer.toString(s);
} else {
return Integer.toString(s);
}
}
// Pass seconds. Returns 00:00:00 stop watch format.
private String buildStopwatch(int s) {
if (s < 60) {
return "00" + ":" + "00" + ":" + formatDigits(s);
}
int minutes = s / 60;
int seconds = s % 60;
if (minutes < 60) {
return "00" + ":" + formatDigits(minutes) + ":" +
formatDigits
(seconds);
}
int hours = minutes / 60;
minutes = hours % 60;
return formatDigits(hours) + ":" + formatDigits(minutes) + ":" +
formatDigits(seconds);
}

Re: Parent Window using Splitters and DialogBox Question
Ok. I figured out what the root cause of the dialog box blending with the parent widget was: If you show the dialog box first before adding the parent widget to the root panel that's when the blending of the dialog box with the parent widget (window) happens. The easy fix is to just add the parent window to the root panel first. Example: // Working way: RootPanel.get().add(_mainPane); LoginDialog login = new LoginDialog(_mainPane, _security); // Bad Blending way: LoginDialog login = new LoginDialog(_mainPane, _security); RootPanel.get().add(_mainPane); On Jan 21, 4:50 pm, "sjn...@gmail.com" wrote: > I have a created a main window that uses vertical and horizontal > splitters, VerticalSplitPanel and HorizontalSpiltPanel.

Re: Parent Window using Splitters and DialogBox Question
Nevermind on this question. The dialog box is working fine now, but I don't know how it was fixed. The problem was that the dialog box and the parent widget with vertical panel splitters seemed to be blending into each other.

Parent Window using Splitters and DialogBox Question
I have a created a main window that uses vertical and horizontal splitters, VerticalSplitPanel and HorizontalSpiltPanel. There's 5 separate panes in the main view. If I try to open a dialog box, DialogBox in the main window the dialog box isn't usable and the app freezes. The only way I found to get around this is to show the DialogBox first and then not add the main screen to the root panel until after the user has finished in the DialogBox.

Re: Hosted Mode Configuration Question
I'll look into the the -noserver option since hosted tomcat is going away. In GWT 1.5.3 copying the web.xml file from the tomcat server to the GWT's application directory: tomcat/webapss/ROOT/WEB-INF/ worked really well.

Re: same-origin security restriction
The light bulb finally lit for me. There's browser security rules in place that only allow Ajax to communicate with the same server as the main page. If GWT hosted mode allowed it then in the future when you deployed to production your app wouldn't work. I'm going to change my implementation to have the external data sources route through the server, but may need to add load balancing because of the extra load now on the server. Nothings ever to easy. On Jan 6, 1:10 pm, Scooter wrote: > Please allow this to either be a configurable option or a prompt when > accessing external URL.

Re: Best way to add App configuration properties
Gregor, I was able to get around it by what Joe Cole mentioned above by just overwriting the GWT applications generated web.xml. It works fine. I even created a subdirectory called lib under WEB-INF and put my third party server side JARs there.

Re: Hosted Mode Configuration Question
To answer my own question, existing web.xml files work fine with hosted mode. I was able to setup log4j, jdom, my singleton and other third party server side configuration by just copying the config into the generated GWT web.xml in ./tomcat/webapss/ROOT/WEB-INF/web.xml and I created a subdirectory called lib and put my third party server side JARS in there and the hosted mode tomcat found them fine.

Re: Best way to add App configuration properties
To answer my own question. It works fine with existing web.xml file.
Just copy them over the generated file as mentioned above.

Hosted Mode Configuration Question
I want to port a small tomcat application to use GWT hosted mode, but I want to know if I can port the following setting to the *.gwt.xml file from the web.xml file? See below. com.toyota.agentstatus.server.controller.FlatFileReaderFactory csv.start.hour 05 java.lang.Integer The first setting is a class that gets loaded on the server at start up as a singleton. As its name suggest it caches the data read from a CSV file. The environment entry tells the singleton to load the cache run at 5:00 AM daily. I didn't see in the docs how to add this to my gwt.xml file. Is there away to add these settings?
