UiBinder - Add Mouse Handler to Panel or Grid
I can't find a way to add a Mouse Handler to a GWT Panel or a Grid while using UiBinder. I basically need a way that I can detect the following over a Grid: 1. Detect what cell the event is happening in. 2. Detect Mouse Up Event 3. Detect Mouse Down Event 4. Detect Mouse Out Event 5. Detect Mouse Over Event I had planned to try and do this with the absolute panel overlayed on top of the Grid. I could detect these events on the AbsolutePanel, then based off of the location of the event, determine what cell the event would have taken place in had the AbsolutePanel not have been overlayed on top of the Grid, and then act accordingly. I now find out that the exact same restrictions are placed upon the panels in terms of click handlers, and don't have many options. I just need to find a way to get the above events to work on the Grid. What would you recommend? Not using UiBinder, I was using DomHandlers, which seam to be disabled in UiBinder (am I wrong?). Any help is VERY appreciated. Thanks! ~Scott -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: how to handle mouseOver event for FlexTable
This code is from my class that extends Grid:
public GridMouseHandler gridMouseHandler = new GridMouseHandler(this);
Later on in the workings of one of the functions I add my mouse
handlers. For grids or flex tables they must currently be implemented
as dom handlers:
addDomHandler(gridMouseHandler,
MouseDownEvent.getType());
addDomHandler(gridMouseHandler, MouseUpEvent.getType());
addDomHandler(gridMouseHandler, MouseMoveEvent.getType());
My function that finds which cell the mouse event happened on:
public int[] getCellForEvent(MouseEvent event) {
final Element td =
getEventTargetCell(Event.as(event.getNativeEvent()));
if (td == null) {
return null;
}
final Element tr = DOM.getParent(td);
final Element table = DOM.getParent(tr);
int returnEventPosition[] = new int[2];
returnEventPosition[rowPos] = DOM.getChildIndex(table, tr);
returnEventPosition[colPos] = DOM.getChildIndex(tr, td);
eventPosition[rowPos] = returnEventPosition[rowPos];
eventPosition[colPos] = returnEventPosition[colPos];
return returnEventPosition;
}
My GridMouseHandler class is just: public class GridMouseHandler
implements MouseDownHandler, MouseUpHandler, MouseMoveHandler { and
then implements the required methods such as onMouseUp, or
onMouseMove, and when the mouse moves you can have them call a
specific function. One of the functions you will want to call is your
own function for finding which cell the event happened on, and then
acting accordingly.
Using this same method you can do similar things for any of the mouse
handlers with Grid.

Storing Session ID in cookie, and then what?
Hey, I'm currently making a site that has my own logins that I'm making (I know Google provides something, but I need my own login system), and I've been trying to figure out sessions for quite a while now. I've found a few tutorials, and one of the sites that I was reading is http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ There is a section there on "How to Remember Logins". I know how to get the session ID and store it on the client in a cookie through an RPC call. What I don't understand is, eventually after a day or so, the user comes back and I'm supposed to get the session ID from the cookie and send it back to the server. What am I supposed to do on the server in order to securely evaluate if session ID is still legal, and pull up all the necessary information about the user? Additional questions: 1. What would make the session ID change? 2. What if the user was on a laptop, and the user went somewhere else. Would he still be able to be securely logged back in without having to type in his login and password again?

Acris Security and App Engine
I've been trying to find out more information about sessions in GWT, as I couldn't figure out how to get them to work, and something that I stumbled across is Acris, which has a Security implementation. I've been reading about it and I can't find detailed information on how to use maven to setup a gwt project, and I'm so confused as to how maven works, or what it's actual purpose is even. However, Acris is something I'm very interested in using. I was searching around trying to figure out how I could do this, and I happened across a post of someone telling someone that acris couldn't be implemented onto projects hosted with AppEngine. Is this true? Also, does anyone have some detailed steps as to how I setup Maven with GWT and Eclipse? I've installed maven on eclipse, but now (from what I gather, I'm taking a leap and concluding this) I have to do some setup in my pom.xml file. I don't know if this is before or after the creation of the project, but I can't figure out how to create a project either, so overall I'm very confused. I'd be thankful for any help at all in this area. ~Scott -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

UIBinder + DOMHandler?
Hey guys, I know that UIBinder disables DOM Events, but I have an application that uses DOM Handlers in order to tell when a mouse up event, or mouse over event has taken place on my grid, and what cell it took place with. The issue is that since UIBinder disables DOM Events, I can't get my DOM handlers to work either. I'm making an application with GWT, that I'd like to use UIBinder, but there is this one part of the application that will being used maybe 10% of the time that requires DOMHandlers to work until GWT adds more mouse event options for Grid. Is there any way that I can get UIBinder to work for most of my program, but for part of my program get it to work through building the UI with function calls? Or perhaps is there a way to get my dom handler to work with UIBinder? Any help at all, or even ideas would be great!

Re: Hosting Entire Website on AppEngine? Integrating GWT into your website?
Joe, Thanks for your fast reply. I figured you'd have you use google's database solution, but I thought it was called datastore. Either way I'm fine with that as long as it works, however using multiple less than operators across multiple entities would be convenient. One of my questions was how would you have a gwt application (or applicationS) spanning multiple html files, however you have your entire website it seems on a single html file. I'm not sure how you did that with your GWT app, but I'm gonna look through your source code and see if I can't figure out how. Through doing that, AppEngine is able to host your entire website, which is what I'd like. I actually have a good portion of my GWT app written. I've got RPC calls working, and I have the ability to use JDO, and make objects persistent, however I've been getting weird errors, and haven't been able to get my queries to work once. So I started thinking about other things and these questions started coming to mind. I thought that if I wasn't going to be able to host my site completely on app engine, why would I even bother with this, and not just use SQL? So apparently I'm going to keep chugging it out with AppEngine. Thanks! ~Scott On Aug 10, 8:50 am, Joe Hudson wrote: > Hi Scott, > > That is what I am doing withhttp://www.gwtmarketplace.com.

Hosting Entire Website on AppEngine? Integrating GWT into your website?
There isn't any way to host an entire website on AppEngine is there? It doesn't seem like it, I just thought I'd ask. So if that's the case, how am I supposed to integrate GWT into my application? an iFrame? Does GWT have any write-ups about this?

Re: GWT Popup Menu - Close on losing focus
Are you wanting it to close when you lose focus, or simply when your mouse exits the panel? In my mind, the popup would lose "focus" when you actually click outside of the popup, rather than just moving the mouse out of it. I'm going to address the question in regards to your mouse exiting the panel as it would be the more difficult thing to do. I'm not sure what you are using for a pop-up method, but I would recommend taking a look at the MouseOutHandler, and the MouseOverHandler. I would add a MouseOutHandler to the popup, so if they moved the mouse out, it would call a method where you could close the popup. Another way to do this is if when the popup comes up, you could create an invisible panel that is in front of your entire program, but still is behind your popup popup, and give it a MouseOverHandler so that whenever it is moused over (meaning whenever you mouseover any part of your program that is not your popup) it will call a method, that you can have close the popup. Something I'd consider beforehand is, what if their mouse is not in the popup when it's created, then it will close really really fast before they have time to read it. You would have to make sure they mouse over the popup prior to it being able to close. If you wanted to do it the focus way, I'd do the latter method listed above, but rather than using a mouse over handler for the invisible panel, I'd use a mouse click handler, or MouseDownHandler. If you are new to GWT Events, I'd recommend taking a look at the following links: http://code.google.com/webtoolkit/doc/latest/DevGuideUiHandlers.html http://gwttutorials.com/2009/07/29/using-gwt-events/ On Aug 6, 1:40 pm, MJ wrote: > I have a menubar with several Popup menus.

Re: Cell click events for incubator's FixedWidthGrid
Are you only wanting to tell if a cell was clicked, or are you wanting to use specifics, such as the MouseUpHandler, MouseOverHandler, etc.? If you are using the Grid and all you want to do is tell which cell was clicked, Grid has a function called addClickHandler() (only works with the click handler to tell if it was clicked), and you can use the getCellForEvent() method to retrieve the actual cell object, and from there call the methods (I think getRow(), and getIndex()), to get the row and column that it's in. If you want to do MouseUp handlers etc, shoot me an e-mail and I can help you with that. That's a bit more convoluted.

Re: onModuleLoad() Before Page Load
I'm not familiar with a lot of the things that you are using, however GWT has a method that it calls after the widget that the method is attached to is loaded. It's called onLoad(). Typically, when I've used it in the past, it's because I was extending a widget, say a Grid, and then I would override the onLoad() method. I'm not sure how you would implement it into a completely custom widget though. You might be able to put the iframe in a HTMLPanel or something, and call the onLoad() method. Either way, I think this may be what your looking for. Hope this helps!

Re: HTML Table
Why are you doing HTMLTable table = new Grid(rows, 2);? Try doing Grid
table = new Grid(rows,2); or HTMLTable table = new HTMLTable(rows, 2);
(assuming syntax for HTMLTable)

Exception while dispatching incoming RPC call Object Manager has been closed (repost)
Hey, I've been trying to get my RPC Call to AppEngine to work since
last Wed, with no luck. My issue now seems to be with my query. I'm
willing to post any code needed, but I just want to get this working,
as this has completely halted me on any further progress on my app.
Everything looks like it should be working. Here is my
TestServiceImpl.java :

My addShift function works fine, and I can add objects to the database
just fine. I just can't retrieve them. I finally changed the objects
in the database to all have an int variable called search, and it's
always set to 1. When I call the getShifts() method though, it gives
me this error:

Error Doing RPC Call with my own return type: org.datanucleus.exceptions.ClassNotResolvedException
Hey, so I can save data to app engine in an entity of type
"PersistentShift", a class I made to save shift information. I've got
2 objects I'm saving within the class. Both are Date objects. One is
startDate, one is endDate. I wanted to be able to query the server,
and have a return type of PersistentShift. In order to do this it was
recommended that I put my Persistent shift class in the Shared
package, as opposed to having one in the client package, and one in
the server package. I've done this, and got it to where I can save
data again, but now I'm getting an error when I try to query that
data. Below is the relevant code. My code compiles with no errors:
package com.spierce7.gwt.scheduler.client;
public class Scheduler implements EntryPoint {
private final SchedulerServiceAsync schedulerService =
GWT.create(SchedulerService.class);
public boolean timerSet = false;
public void onModuleLoad() {
//Date startDate = new Date();
//Date endDate = new Date();
//endDate.setHours(endDate.getHours()+1);
//addShift(startDate, endDate);
loadShifts();
}
private void loadShifts() {
schedulerService.getShifts(new
AsyncCallback>() {
public void onFailure(Throwable error) {
Window.alert(error.getMessage());
}

Re: add mouse handlers for document body?
What do you mean by document body? You might want to look into a DOMHandler. That's how I got mouse move handlers to work on my grid. Grid's don't have an obvious method that allows you to add a MouseMoveHandler like a lot of other things do (grids only have addMouseClickHandler). I'd take a look again at what you want to add the handler too and make sure it doesn't have an obvious method like that. Another option is wrapping things in an HTMLPanel, which would allow you to add a MouseMoveHandler, etc. ~Scott On Aug 5, 10:11 pm, "Randy S." wrote: > I'd like to add a MouseMoveHandler and MouseUpHandler to the > document's body, but haven't discovered how.

Re: Please help - GWT application will not load in IE!
I hate issues like this. Unfortunately, particularly since GWT is young, I've gotten something working in one browser, only to find it doesn't work in another browser. Typically I just find a more common way of going through something. What I'd recommend is (although it's time consuming), is to comment out the method that builds your entry GUI, and start adding stuff back slowly until you get the issue. Try to get it down and figure out exactly what isn't able to load in I.E. The fact that nothing is loading makes me think it might be one of the outside layers, perhaps try some inner layers of the GUI and see what works and what doesn't. If I got your code, that's what I'd end up doing any ways. Errors like this can just happen for random reasons, and to my knowledge there isn't a "well this works in all the other browsers, but not I.E." error. Google has been good about fixing those if I'm not mistaken. On Aug 6, 7:41 am, Xandel wrote: > Alright, so I tried RootLayoutPanel.get() instead of RootPanel.get() > and something interesting...

Re: Any Good GWT Photo Uploaders?
I don't think you would upload 150 files simultaneously. I think it would probably be faster to do 2-4 at a time. I get that idea, because torrent programs typically try to limit downloads to 3-5 simultaneous downloads. Once you establish a lot of connections, it seems like it might slow bandwidth down. Any thoughts? This is just my own assumption.

Re: MacBook ok for GWT development?
I have the i7 15 inch macbook. It's a bit much just for programming to be honest. One of the i5's would be fine, or even a used 2.8 Ghz Core 2 Duo off craigslist. What's your current processor, and why do you feel it's "unbearably slow"? My i7 barely reaches 40% when I do anything, but maybe that's because I have a computer that is fairly fast.

ExceptionInInitializerError during an RPC call.
I'm getting an error while trying to save an object to the database. I'm keeping it simple. I'm just saving an event with a key, a start date, and an end date. I had the ability to save an event to the server working with an Event class on the server that was @PersistenceCapable, and an Event class on the client. The problem came in when I was trying to use Event as a return type, as my Service and Async methods couldn't tell the difference, and it was recommended that I make my Event class in the shared package. Now I've deleted my server Event class, and moved my Event class from the client package to the shared package. I made it implement IsSerializable, and added the proper @PersistenceCapable annotations etc. Now I'm getting this error and can't figure out why. Any help would be great!

AE / GWT Newb: How to do RPC Call with my own return type?
Hey guys, I've been mess making an app for a while now, and I've finally got something that is able to save an entity on the server. That entity (to keep it simple) is of type Event. It has 2 Date objects: startDate and endDate. I understand how to do queries and what not, but what I found my program encountering issues with is in my method within the ServiceImpl, getEvents(), it's having a difficult time distinguishing between my client side Event object and my server side. This creates issues when I try to have my return type as List. How should I be handling this? Does the client side Event object need to be serializable? I've tried this, still without much luck. On the client side Service, and ServiceAsync classes, should I be declaring the types through the server side object? Example: public List getEvents(); or should I perhaps be doing the same thing, but with the client side on the server? I've tried both of these, but can't seem to get it to be happy with whatever I put. Any direction in this would be greatly appreciated!

Error using my own widgets with UIBinder
Hey, I'm getting an error using my own widgets in UIBinder. In this
I'm using the DockLayoutPanel, and everything works fine until I swap
the Label that everything was working with in with my own
widget, WeeklyHeader. I'm getting the following error:

The best guess I've got is that my widget is supposed to extend
something, or implement something. I can't figure it out for the life
of me. Any help is much appreciated.

Needs Scroll Panel and Resize Help
Hey, I'm trying to make a program that is very similar to Google
Calendar. One of the things I'm currently trying to implement, is I
want the top line in the grid to maintain stationary, while the rest
of the calendar is scrollable (this way the dates over the columns are
always visible. So I broke the first row of the calendar off into it's
own Object called weeklyHeader, and set it to the same style so that
it would match, but now since it's apart I have to have it resize, and
the way I've currently figured out how to do that, I'm not very happy
with, as it's laggy. I've also noticed that now since I've added the
resize handler, the entire browser lags when I resize it (Make the
browser window small, and play around with it and you'll see what I'm
talking about). What else can I do to fix this?
My second issue that I'm dealing with is I'm trying to add a scroll
panel to the actual calendar part, however the only way I've gotten
this to work is through setting an actual pixel height rather than a
percent, and I think I need it to be a percent. I can't have it as a
percent though because their is one other widget that takes up 19
pixels above it. What can I do to make the scroll panel have dynamic
height in terms of browser height?
Here is a link to my program so you can see what I am talking about:
http://internetexample.appspot.com/
Here is my EntryPoint code so you can understand how I have things
currently set up:
public class Scheduler implements EntryPoint {
public boolean timerSet = false;
public void onModuleLoad() {
VerticalPanel verticalPanel = new VerticalPanel();
final WeeklyHeader weeklyHeader = new WeeklyHeader();
ScrollPanel scrollPanel = new ScrollPanel();
WeeklyAbsolutePanel weeklyPanel = new WeeklyAbsolutePanel();
final WeeklyGrid weeklyGrid = new WeeklyGrid(weeklyHeader,
weeklyPanel);
weeklyHeader.setWeeklyGrid(weeklyGrid);
verticalPanel.setWidth("100%");
verticalPanel.setStyleName("verticalPanel");
verticalPanel.setSpacing(0);
scrollPanel.setHeight("800px");
weeklyPanel.add(weeklyGrid);
scrollPanel.add(weeklyPanel);
verticalPanel.add(weeklyHeader);
verticalPanel.add(scrollPanel);
RootPanel.get().add(verticalPanel);
final Timer resizeTimer = new Timer() {
@Override
public void run() {
weeklyHeader.onLoad(); //this calls a an
overridden onLoad() where
I have the super.onLoad() called and
setWidth(weeklyGrid.getOffsetWidth() + "px");
timerSet = false;
}
};
// Handle window Resizing
Window.addResizeHandler(new ResizeHandler() {
public void onResize(ResizeEvent event) {
if(!timerSet){
resizeTimer.schedule(50);
timerSet = true;
}
}
});
}
}
ANY help would be greatly appreciated. I'm a GWT newb pretty much
trying to figure things out as I go along, so please don't assume I
may have done something I should have. Thanks!

Stop Cell Selections in a Grid
Hey, I have a grid where I have some click and drag features on, but
the problem is whenever I drag, the grid will select multiple rows of
cells in the grid. How can I keep this from happening, besides using
the css select option:
".notclickable { cursor: default; user-select: none; -moz-user-select:
none; -webkit-user-select: none; } "
That only works in a few browsers, and I need something to work on all
major browsers. Someone recommended the Event.sinkEvents but I have no
idea how to apply this to a grid or other objects. Any help in any
direction would be appreciated!

Get today's date, and the first day of this week's date?
Hey guys, I just found out that the Java Calendar class isn't compatible with GWT (Assumed it was since Date was). I'm a Java newb and spent a few hours figuring out how to do what I wanted to do with the Calendar class, and I'm clueless how to do this with GWT, so any help would be appreciated. 1. Get today's date. 2. Using the current date, get the date of the first day of the week (Sunday), and I think I might need to know how to get the end date also. 3. How to Add and subtract a number of days to a date. 4. I need to know how to parse all the above questions information into a string. Off the top of my head, that's what I'm trying to do. 1 More question: 5. Would it improve performance while handling a start date and an end date for an event, instead of keeping an end date, calculating the duration that the event would last, rather than calculating the date? Would it even be worth it? (A friend recommended this) 6. Are we seeing any updates coming for working with dates?

Re: Touchscreen laptops - access touch events?
I don't think there is a way to access touch events in and of themselves. Touch screens are just simply another way of controlling the mouse for the computer. In terms of phones, when they touch a link, its equivalent to them clicking the link. Basically what I'm saying is that a touch event should be looked at by the browser, and thus GWT, as just simply a mouse click/move.

Get Grid HTML objects for Cells within a Grid so that I can add Mouse/ClickHandlers?
Hey, I need to be able to have events within a grid for mouse overs, mouse ups, etc for individual cells on a grid and since it seems that I can't add a click handler for mouse overs etc for the whole grid, I'd like to be able to get at the individual HTML objects for cells, or an html object that's consistent for each cell or row or column, so that I can add different mouse handlers to them, and don't have to add my own html objects to each cell.

How do I detect Mouse Up, Mouse Out, Mouse Over, etc on Grid Cells?
I need to be able to do this efficiently in a 50X8 Grid. I need it for the individual cells within the grid. It seems that all I can get to work on my grid is a simple click handler. Grid.addClickHandler(this); and then whenever a click event occurs (a click down and then a click up in the same cell), it fires public void onClick(ClickEvent event). I need much more usability than this for my individual cells. I was playing around with the idea of possibly adding a blank html object to each of the cells and having it fill the cells, but this seems like it would be slow, and I would run into some problems down the road with table borders. Is there a way that I could access the Grids native HTML cell objects themselves? If I could somehow access those I would be able to add click handlers and what not. Still not an ideal method, but better than adding my own HTML panels and dealing with border issues.

Re: Need a way to get width of each column in a Grid
Never mind guys. Figured it out. Just in case there are any searches:
public CellFormatter cellFormatter = new CellFormatter();
public Element cellElement;
and then I made 2 methods that I found very useful within my class
that extends Grid:
public int getColumnWidth(int column) {
cellElement = cellFormatter.getElement(0, column);
return cellElement.getClientWidth();
}
public int getColumnOffset(int column) {
cellElement = cellFormatter.getElement(0, column);
return cellElement.getOffsetLeft();
}
in the getElement function you can specify a row also, but I chose to
use 0 because all my columns in a given row have the same width. Be
wary though, I've noticed it rounds. I used a similar method to get
the total width for the table, and then I subtracted all the column
widths while the borders were set to 0, and the result I got was -3.
So there is slight rounding going on, which is why I found the
getOffsetLeft method of Element so useful since its more accurate for
me to get exactly where something is placed.
Best of luck!

Need a way to get width of each column in a Grid
I'm trying to find a way to get the specific width of each column individually within a grid. Height isn't as important, but I wouldn't mind knowing that either. I don't need the table total width, but rather specific columns. Getting the absolute location of a cell, column, or row might also work.

onLoad?
Hey guys, I'm creating a class that extends Label, and for some reason whenever I create an instance of it, it doesn't load the onLoad() class when it's instantiated. I've got it set up the exact same way I have a class that extends grid, that properly uses onLoad, but for some reason this isn't.

Can't figure out how to edit a Grid's border
Alright, so I'm not sure how to properly figure out how to do this. I've been trying to figure out how to do it for a few hours now without much luck. I've tried playing with some CSS settings, and then using the grid.setBorderWidth() method, but nothing seems to work. The space in-between the cells that I'm working with (the best way I can describe it is the grid of the grid). I'm not 100% which I want, but I need a way to make that space go completely away, or make it another color. I can't figure out how to edit that space. I can make the space bigger with the setBorderWidth() method, but I can't make it go away. Any help is appreciated.

Re: GWT Noob: Click Handlers and Grid/Flex Table
I finally figured out my own answer to question 1. I had to make an
HTMLTable.Cell object and set it equal to the results of the
getCellForEvent(event), then from there call some functions to get the
cell indexes. I had tried that but forgot to capitalize the C in Cell.
Anyways, I'd still really love input on questions 2 and 3. :-)

GWT Noob: Click Handlers and Grid/Flex Table
Alright, so I am trying for the life of me to understand how to do
this. I'm a GWT noob at the moment, and I'm really struggling to
understand how to fully implement clickhandlers in a grid or flex
table to figure out where they are clicking within the grid.
Apparently from what I can see so far is that individual click
handlers for each location in the grid were not meant to be
implemented. Instead it seems that I can implement a single click
handler for the entire grid, and then somehow using "getCellForEvent
(ClickHandler handler)" I can figure out where was clicked and then
have it react, but I can't seem to figure out how to implement
getCellForEvent() into my code. Here's what I'm using:
private Grid calendarGrid = new Grid(4,4);
private int cellNum;
public void onModuleLoad() {
// Put some values in the grid cells.
for (int row = 0; row < 4; ++row) {
for (int col = 0; col < 4; ++col)
calendarGrid.setText(row, col, "(" + row + ", " + col + ")");
}
calendarGrid.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
getCellForEvent(event);
}
});
RootPanel.get().add(calendarGrid);
}
What I'm ultimately trying to do:
I'm trying to make something very similar to what's here:
http://google.latest.gwt-web-calendar.appspot.com/
I need to make a calendar-ish program but have some unique
functionality. Everything will be easy enough, but I need to have an
in-depth understanding of how to manipulate the events on such a
calendar once I have it made. The reason I bring this up, is because I
currently intend to have the calendar aspect just be one big grid, and
act according to clicks and drags. I'm not sure if this is a very
efficient way though, and I can't figure how I would display multiple
events, but once I get that figured out I need to have the events
dragable. That seems manageable on a grid (I think), I'm just not sure
how I would limit events to parts of a grid space.
So my questions:
1. How would I implement getCellForEvent into my above code?
2. Do you think my current idea of how to implement my program idea is
going to be effective? Is there perhaps another way you feel I should
do it?
3. What way would you recommend I handle events within the calendar?
That seems to be the part that I'm having the most difficulty
conceptualizing at the moment.
Thanks in advance!

Re: Need to use GWT to make a program similar to Google Calendar, How would you do it?
@Chris, The first link you gave was actually the link that I originally linked. I'd love to see Ray Ryan's talk on Model View Presenter design though. Also, that DND library is pretty awesome though! That is definitely useful! Thank you for that! @Paul, That calendar is much better made than the one I found... Thank you for that. I think I might end up just trying to edit that rather than re-create the wheel. Or at least try to understand how he did it, and maybe get a better idea for how to make mine. Thank you!

Need to use GWT to make a program similar to Google Calendar, How would you do it?
I found this online: http://google.latest.gwt-web-calendar.appspot.com/ Again, my goal is to make something similar to that, but something that's more customized to my needs. Instead of editing his code, I'm just going to make my own so I'll learn during the process as well. I'm reasonably experienced with programming, and I've spent a few hours here and there over the past few weeks reading over some articles and going through some of the tutorials for GWT. I think I'm ready to kind of dive head first and give this a shot, but I figured I'd ask for some advice beforehand since I don't have a ton of experience creating GUI interfaces. So right now, I'm looking at making a few panels, and inside one of the panels having a big table, then having click/drag listeners respond by changing cell color as I drag over something. Somehow though, I kind of feel like this isn't going to leave me with a very good working or good looking product. Right now, I think it's more important to get everything working, and smooth everything up later, but at the same time, I'd rather not just flat out waste time, so I'd love any input you can give me.

Is Google Web Toolkit for me?
Hey, I'm looking to make a webapp, and right now I'm really intrigued by what the Google Web Toolkit offers. I'm familiar with PHP, MySQL, HTML, and CSS from a few years ago, and I've taken a few Java classes a few years back. Right now I'm trying to make a Web App that is very similar to a calendar that is going to manipulate dates and times and what not. I was going to use AJAX to connect with the server, and PHP to manipulate the dates etc. Anyways, I read some articles, such as this: http://www.ryandoherty.net/2007/04/29/why-google-web-toolkit-rots-your-brain/ and was wondering what you guys have experienced with this. I LOVE google products, so I figured this couldn't be bad, but I thought I'd get a second oppinion before I started devoting large amounts of time learning to do something to just find that I'd have been better off sticking with PHP, JS, & CSS. By the way, I'm going to need to integrate with a web database. The obvious one for me was MySQL, but that was mainly because PHP integrates so easily with it. What kind of options do I have with this while using GWT? I'd rather not have to have GWT integrate with PHP, and then MySQL, or some other ridiculous thing. What options do I have here?
