More than one constructor annotated with @UiConstructor
Hi all
I have my own convenient composite which is a HorizontalPanel with a
Label and TextBoxBase, called FormEntry. I have 4 different
constructors for this composite, where some take just a label text
string and others also take a default value and a boolean determining
if the TextboxBase should be PasswordTextBox or a TextBox.
Now, I am trying to convert my project to use the new UiBinder
feature. I figured based on
http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Using_a_widget
that I could annotate all my constructors with @UiConstructor and then
in the ui.xml use the name/or number of constructor arguments to match
it to the right constructor.
So for example in the ui.xml I have
my:FormEntry ui:field=username labelText=Username
defaultValue=nina /
my:FormEntry ui:field=password labelText=Password
defaultValue=pass123 password=true/
and in the FormEntry.java I have
@UiConstructor
public FormEntry(String labelText, String defaultValue){
this(labelText, defaultValue, false);
}
@UiConstructor
public FormEntry(String labelText, String defaultValue, boolean
password){
// code...
}
The error message I get is FormEntry has more than one constructor
annotated with @UiConstructor.
I've looked for more info on how this @UiConstructor works but haven't
found anything. So the question are:
- do I have the right approach here?
- why can't I have more than one constructor marked with
UiConstructor?
- does the binding happen with the help of the constructor arg names
or numbers or types or what?
Many thanks for any tips!
Nina

Doubleclick event handling
Could I please get some clarification on how to use the double click
event handling? The classes are there (e.g.
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/event/dom/client/HasDoubleClickHandlers.html)
but don't seem to be implemented anywhere.
I would like to add double click handling to an Image, could someone
please give me some example snippet of code on how to do this? I've
tried simple things like extending Image and implementing
HasDoubleClickHandlers, e.g.
private class CommandButton extends Image implements
DoubleClickHandler, HasDoubleClickHandlers {
private HandlerManager clickHandlers = new HandlerManager(this);
public CommandButton(){
super(images/favicon-2.png);
addDoubleClickHandler(this);
}
@Override
public void onDoubleClick(DoubleClickEvent event) {
Log.debug(doubleclicked command button);
}
@Override
public HandlerRegistration
addDoubleClickHandler(DoubleClickHandler
handler) {
return
clickHandlers.addHandler(DoubleClickEvent.getType(),
handler);
}
@Override
public void fireEvent(GwtEvent? event){
handlers.fireEvent(event);
}
}
but of course this doesn't handle double click events.
Thanks!

Re: Understanding KeyUpEvent
Just to clarify what I am trying to do here: I am after a modal key
input state, where when I hold down control and alt, display a
Dialogbox with a textbox, and when I no longer hold down control and
alt, I want that dialogbox to go away. Same concept as the shift key
to get upper case letters. So, I figured detecting when the user had
let go of the control and alt key by using the KeyUpEvent would be the
way to go here. But this event gets fired constantly when these two
keys are held down, which I find very confusing.
I am using FF3.

the onKeyUp method is NEVER called when any key is released, but
ALWAYS for as long as any key is pressed down. I expected the opposite
to happen. Could someone please enlighten me on how to capture the
fact that a key was released? I'm using 1.6.4.
Many thanks from a very confused

Re: Getting item select events from suggestbox list
Hi Zamek Have you read the http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/SuggestOracle.Suggestion.html about the Associating Data Transfer Objects (DTOs) with Suggestion Objects? I've written my own SuggestBox, SuggestOracle and Suggestion, using the implementation of MultiWordSuggestOracle as inspiration, and didn't find it difficult. In your custom Suggestion, you have your DTO, so in the onSelection callback you get access to the DTO. Good luck Nina On May 4, 11:16 pm, zame...@gmail.com zame...@gmail.com wrote: Hi All, I am using SuggestBox, and there are DTO-s in list. When a user selects items with up and down key, I need to get the selected element to display all data of DTO item on a detail form. It seems to be, there are not a standard event for this. How can I implement this functionality? I need some tips, not a full solving. I can't inherit SUggestbox, because popup panel is private. Can I make an own SuggestBox? Unfortunately it depends on Menubar, because it using protected methods of Menubar:( thx a lot Zamek --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

DatePicker and keyboard navigation?
Hello there Does anyone know if it's possible, or will be a future feature, to have keyboard support for the DatePicker widget? It would be nice if you could use the tab key to give it focus, arrow keys for navigation and enter or space for selection.

Re: GWT 1.4 DisclosurePanel Horizontal Orientation
Just a note to others who may have the same need: I found http://code.google.com/p/gwt-majic/ very useful. It does sliding, fading and other handy things. It's easy to use and the demo worked out of the box straight in Eclipse.

Padding in FlexTable/HTMLTable leaves rows behind on removeRow()
I have a FlexTable that the user can add and remove rows from. However, I have noticed that when I have any cell padding at all, this padding is left behind when I call removeRow(rowNo). This is particularly noticeable when the user has added a few rows and then removes all of them (one by one): there is a big white space left, which wasn't there before the rows were added and removed. If I call setCellPadding(0), this problem goes away. I have inspected the html using Firebug, and the white spaces left behind are empty tds inside trs. Has anyone else had this problem? Am I doing something the wrong way, or is this a bug? Thanks Nina --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
