Contribution: FlexTable with Model support
Hi guys,
Recently I stumbled upon the high-performance CellTable. In particular, I
like its model-based approach compared to FlexTable's or Grid's
't.setText(x,y,content)'. In my case, I don't care about performance
(internal app) and I'd rather like to use all the Widget goodness that I'm
used to. So, as a result, I added model support to FlexTable which then
allows me to do the following:
ModelFlexTableModel table = new ModelFlexTableModel();
table.addColumn(new FlexColumnModel() {
@Override
public Widget createWidget(Model row) {
return new Label(row.getName());
}
}, Name);
table.addColumn(new FlexColumnModel() {
@Override
public Widget createWidget(Model row) {
return new InlineHTML(div style='background-color:
+ row.getColor() + ; width:50px;height:50px'/div);
}
}, Color);
table.addColumn(new FlexColumnModel() {
@Override
public Widget createWidget(final Model row) {
Button remove = new Button(Remove);
remove.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
table.removeRow(row);
}
});
return remove;
}
});
table.addRow(new Model(red, #ff));
table.addRow(new Model(green, #00ff00));
where the Model class is:
public class Model {
private final String name;
private final String color;
public Model(String name, String color) {
this.name = name;
this.color = color;
}
public String getName() {
return name;
}
public String getColor() {
return color;
}
}
Maybe someone finds this useful. The downside is that the nice default
styling of CellTable is missing, and other features of it like paging etc.
So it's not a CellTable replacement but rather a nicer-to-use FlexTable if
you have a model anyway.
Code is at https://gist.github.com/neothemachine/5857263
Cheers
Maik

Re: Dynamic CompositeCell
I have the same problem at the moment. I can't use a CellTree because I actually want this to be a column of a CellTable. And as CellTree is not a Cell itself, this is not possible as far as I see. Is there any other way than going down to HTML and doing everything on my own? What I want is a column where each cell contains a variable number of labelled Checkboxes (label through text attribute of the Checkbox widget). Am Freitag, 27. April 2012 16:09:52 UTC+2 schrieb Alfredo Quiroga-Villamil: If you have an n number of values that should be represented in one single column, I would go for a tree. Its ability to expand nodes when needed, gives the user a chance to have it expanded or collapsed.

Re: Dynamic CompositeCell
Jens wrote: You have to implement your own custom Cell for use in CellTable. Letting a cell render a dynamic list of checkboxes doesn't sound that hard to me. GWT can't provide cells for every possible use case. Well, ok, I probably will do that for the checkboxes. But in my mind this allows for nearly no reuse. If instead there would be something like a CompositeCell where the number and type of child cells depend on the row value, then this would be reusable in lots of cases. And considering that this issue pops up quite some times on the internet I guess it would be useful. To be honest, I find creating custom Cells hard, because it feels low level and also because Cells are completely different to use compared to their counterpart widgets (e.g. Checkbox vs. CheckboxCell). That's why I'm happy if there's something existing I can just use or plug together (like the CompositeCell for fixed Cell number). Do you think it would be hard to create a DynamicCompositeCell for variable Cells? I don't have much experience with cells yet, only with regular widgets, but I'd like to tackle that challenge if I get a little help or advice.

JUnitShell: Why is the log level overriden to WARN?
Hi,
when developing JUnit runstyles I want to do info/trace logging, e.g.:
shell.getTopLogger().log(TreeLogger.TRACE, Letting PhantomJS fetch +
url);
I have to change all those logging outputs to at least WARN to see
anything. This is caused by the following code in JUnitShell I guess:
// Override log level to set WARN by default..
registerHandler(new ArgHandlerLogLevel(options) {
@Override
protected Type getDefaultLogLevel() {
return TreeLogger.WARN;
}
});
My question is: Why? I find it very strange that I can't set a custom log
level via command line argument or system property. What is the reasoning
behind this and can it be changed?
Cheers
Maik

Remote debugging with gwt:debug works, with Eclipse it doesn't
Hi,
I am trying to debug a GWT app which is deployed on a Glassfish 3 server.
When I use gwt:debug from command line, everything works as expected.
However, I want to use it directly in Eclipse and therefore created a run
configuration with Debug as - Web application (running on an external
server), where the args are:
-war /home/.../workspace/project/.../target/admin -remoteUI

The project uses GWT 2.4, but I guess this wasn't an issue that was fixed
in 2.5, right?
Do you have any idea why this isn't working? I do have the GWT 2.4 SDK
installed and setup in Eclipse.

[gwt-contrib] Adding wrap method to Canvas and/or make constructor protected
Hi, I'm using 2.5.0rc2 and find the Canvas class not useable if I use JS libraries through JSNI which give me canvas elements (I'm contributing to KineticGWT, a wrapper for KineticJS). There's no wrap() method like in the other widget classes and I can't even solve it by subclassing Canvas, as the constructor is private: private Canvas(CanvasElement element). This issue has been raised a year ago here: https://groups.google.com/d/topic/google-web-toolkit/xNA8wPpp9RY/discussion Could this be fixed for the final 2.5.0? Cheers Maik -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: Create Canvas widget from CanvasElement
I stumbled upon the same thing today. I'm a contributor to KineticGWT which is a JSNI wrapper around the KineticJS library. In this library, the canvas elements are created by the library itself and I only get them. So I thought, when doing something like layer.getCanvas() it would be best to use the Canvas widget, but still, as of 2.5.0rc2 the constructor is private and there's no wrapper method. This sucks! I'll see if it's already been mentioned in gwt-contributors. Cheers Maik -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
