Re: How To Simulate KeyPress
I have a question related to this. I have a KeyPressHandler in the TextBox. When the user presses "Enter", I want to simulate it as "Tab". I have added the necessary code to capture the 'Enter" event, and then I fire the new event using the DomEvent.fireNativeEvent. NativeEvent tabEvent = Document.get().createKeyPressEvent(false, false, false, false, 9, 9); DomEvent.fireNativeEvent(tabEvent, textBox); What I am hoping to see is the 'tabbing' of the current cursor to the next Focusable widget, but it doesn't seem to happen. What am I missing? It basically re-enteres the KeyPressHandler since this is the widget that is being fired. In short, I need the way to suppress the current KeyPressHandler and have the Browser level KeyPressHandler of the 'tabbing' to occur. Any help is appreciated.

Adding CSS style dynamically
Hello.
I have some odd situation where I need to add the style attributes
dynamically/programmatically depending on what the saved data is.
In short, instead of defining the css style definitions in the file
and reference them, I need to create those per Widget, depending on
the data.
I tried to use DOM.setElementProperty, but it doesn't seem to work
properly. It doesn't set the background or the foreground, and the
absolute positioning also gets screwed up.
Can anyone share your tips/insights on how I can achieve this?
private void setStyle(Element dom, ScreenElement e) {
DOM.setElementProperty(dom, "position", "absolute");
DOM.setElementProperty(dom, "top", e.getYpos() + "px");
DOM.setElementProperty(dom, "left", e.getXpos() + "px");
DOM.setElementProperty(dom, "height", e.getHeight() + "px");
DOM.setElementProperty(dom, "width", e.getWidth() + "px");
DOM.setElementProperty(dom, "fontSize", e.getFontSize() + "pt");
DOM.setElementProperty(dom, "fontFamily", e.getFontFamily());
DOM.setElementProperty(dom, "backgroundColor",
e.getBackColor());
DOM.setElementProperty(dom, "color", e.getForeColor());
if (e.isFontStyleUnderline()) {
DOM.setElementProperty(dom, "textDecoration",
"underlined");
}
else {
DOM.setElementProperty(dom, "textDecoration", "normal");
}
if (e.isFontStyleItalic()) {
DOM.setElementProperty(dom, "fontStyle", "italic");
}
else {
DOM.setElementProperty(dom, "fontStyle", "normal");
}
if (e.isFontStyleBold()) {
DOM.setElementProperty(dom, "fontWeight", "bold");
}
else {
DOM.setElementProperty(dom, "fontWeight", "normal");
}
}

How to add "remove" icon on TabLayoutPanel
Hello there.. First time here, so be gentle with me. :-) I've searched around, but couldn't find the answer to my question, so here it goes. I have added the Tab(s)s to the TabLayoutPanel through UiBinder and programmatically. However, I needed a way to remove this tab from the TabLayoutPanel when the user clicks on the "x" icon or similar in the Tab header. I can't seem to find the way to add this "x" icon to the header, nor a way to extend the to provide the image or a text. Can anyone help or direct me to the link where I can find more info? Cheers. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group. To post to this group, send email to google-web-tool...@googlegroups.com.

erro while try to do "Store data in the datastore" Example
Hi, I would like some help to resolve this problem at the example of
GWT using Gdatastore:
http://code.google.com/webtoolkit/tutorials/1.6/appengine.html#data
All application run well following the getting start tutorial, so when
I try to improve using data store at this implementation an erro
occurs because stockService is not declare yet.
I tryed to force the declaration using "StockService stockService =
GWT.create(StockService.class);" but another erro is get with the
method getStocks.
private void loadStocks() {
stockService = GWT.create(StockService.class);
stockService.getStocks(new AsyncCallback() {
public void onFailure(Throwable error) {
}
public void onSuccess(String[] symbols) {
displayStocks(symbols);
}
});
}
private void displayStocks(String[] symbols) {
for (String symbol : symbols) {
displayStock(symbol);
}
}
If there is no mistake I would like to know where I can download the
caomplete example with datastore workings.
Ty.

Re: Slow data loading to a FlexTable
Hello all, And we are generating the Table HTML on server side, and put it as innerHTML and have performance 1000 rows - 3-4 second in IE. The biggest problem is using components which should handle events and placed in such table, but it seems JSNI is a solution in this case. In our case Links already working. So it seems this is the optimal solution if you need high performance.

Re: GWT applications memory management
Hello Bob, Thanks for answer, I'll check the article on Microsoft. Considering the natives, we have prepared test application, where we exclude all natives, DOM class method calls, and even eventListeners. Sometimes browser frees some memory, but not all (after memory release, total browser's memory allocation is greater then before allocation). So the problem seems still exists.

GWT applications memory management
Hello all. I'd like to ask the question about the approaches normally used to manage memory in GWT applications. Till the moment I wrote this post, I read most of discussions on the group related to this topik, but unfortunately have no answer on my question. What I'm actually looking for: is some guide or list of rules "What is necessary to be done in GWT code, to prevent GWT application to consume more and more memory". This problem occurs in Internet Explorer. Currently we are developing rather big application using GWT. During developement process we had noticed that Internet Explorer consumes memory more and more and never release it. We had also noticed that after we press refresh button in IE, it finally releases most of consumed memory (but not all). We try to check out pages with IE leak detectors, sIEve, and Microsoft JS Memory Leak Detector. Those tools are not detect any memory leaks in our application. After this we create very simple test. We create SimplePanelwidget, and put some FlexTable on it. After this we put in this flex table different widgets (Buttons, checkboxes, etc.). After we add SimplePanel to the rootPanel, and remove it from root panel. Do this several times (using timer). After each cycle (add, remove SimplePanel from RootPanel) some amount of memory ~200 KB is not released. So my questions are following: - Does the situation when IE is not released all memory it consumes is know issue or not? - Does anybody know what may be done to reduce or remove at all memory leaking? - Does anybody have URL to some guides of memory management in GWT applications?

That theory could be tested by changing " indexCounter++" to "indexCounter = indexCounter + 1".
