Is it possible to change the decimal seperator of GXT Numberfield from point to comma? I searched and tried a lot, but can't find a solution.
When filling the form field of type "FloatField" with a number like 67,8 - the value of the field is switched to 67.8. So the field accecpts inputs with commas, but the NumberFormat to display it, is simply wrong.
How can i change that?
Thanks in advance, David.
ok, nobody had an answer, but a colleague of me have had the same problem and solved it. So, if anyone in future will search for it, here is the answer:
You can make your own FloatField class and override the behavior. The class (in the simpliest form) would be like this:
package org.example.myforms
public class FloatField extends NumberField<Float> {
/**
* Constructor
*/
public FloatField() {
super(new NumberPropertyEditor.FloatPropertyEditor());
init();
}
private void init () {
// disply float values with comma as decimal seperator
String pattern = "0.0;";
super.setFormat(NumberFormat.getFormat(pattern));
}
}
To use this field e.g. in your *.ui.xml you have to import your myform package:
<ui:UiBinder
...
xmlns:myform="urn:import:org.example.myforms"
>
Then you can use it:
<myform:FloatField ui:field="field_1" allowDecimals="true"/>

I want that every time I use yup.string(), it will add a specific default value for it
for example:
const schema = yup.object({
text: yup.string()// I want it to also do .default('some string') in the background,
});
or - another option - is there any way to set the default value after creating the scheme? something like setDefault('text', 'some string')
The closest solution I came across to solve your issue is extending your string with a custom method that implements your needs. To do that you need to use addMethod from yup:
import { addMethod, string } from 'yup';
addMethod(string, 'append', function append(appendStr) {
return this.transform((value) => `${value}${appendStr}`);
});
Now, you can use your custom method (append) and apply it to any string you want:
string().append('~~~~').cast('hi'); // 'hi~~~~'
If you want to add the custom method to all your schema types like date, number, etc..., you need to extend the abstract base class Schema:
import { addMethod, Schema } from 'yup';
addMethod(Schema, 'myCustomMethod', ...)
Extra
For Typescript
In your type definition file, you need to declare module yup with your custom method's arguments and return types:
// globals.d.ts
import { StringSchema } from "yup";
declare module 'yup' {
interface StringSchema<TType, TContext, TDefault, TFlags> {
append(appendStr: string): this;
}
}
Unknow behavior for transform method
While I was trying to extend the functionality of the date schema with a custom method that transform the date that user enters from DD-MM-YYY to YYYY-MM-DD, the custom method broke after I used it with other methods like min, max for example.
// `dayMonthYear` should transform "31-12-2022"
// to "2022-12-31" but for some reason it kept
// ignoring the `cast` date and tried to transform
// `1900` instead!
Yup.date().dayMonthYear().min(1900).max(2100).required().cast("31-12-2022") // error
To work around this issue, I appended my custom method at the end of my schema chain:
Yup.date().min(1900).max(2100).required().cast("31-12-2022").dayMonthYear() // works as expected
This issue is mentioned in this GH ticket which I recommend going through it as it's going more in-depth on how to add custom methods with Typescript.

I just want to make sure I'm not doing something wrong before I file a bug/start digging in GWT-Charts code...
Trying to style a LineChart:
DataViewColumn ret = DataViewColumn.create(new ColumnFunction() {
#Override
public Object calc(DataTable dataTable, int row) {
if (dataTable.isValueNull(i, dataColumn)
|| dataTable.getValueNumber(i, dataColumn) < value) {
return "color: red";
}
return "color: green";
}
}, ColumnType.STRING);
ret.setRole(RoleType.STYLE);
(I had to add RoleType.STYLE myself, custom-built 0.9.11-SNAPSHOT off Master)
But adding that column results in (using new JSONObject(columns)):
{
"0":{"sourceColumn":0},
"1":{"sourceColumn":1, "label":"Data"},
"2":{"calc":{}, "type":"string", "role":"style"}
}
Note the empty set for "calc"?
I tried just doing a ColumnFunction for Data (returning a flat value) in case the "style" Role required more than just adding to the RoleType Enum, and that also doesn't seem to be getting passed through.
The JSNI in DataViewColumn.setCalc(ColumnFunction) seems to be right to me, so I'm not sure where the issue lies...
UPDATE:
Putting debugging statements in the ColumnFunction showed it to be running, but the output didn't seem to be getting used.
Turns out that DataViewColumn.setCalc was missing the return statement in its JSNI wrapper.
DataViewColumn.setCalc:
/**
* Sets a function that will be called for each row in the column to calculate a value for that cell.
*
* #param columnFunction a function for calculating each row value
*/
public final native void setCalc(ColumnFunction columnFunction) /*-{
this.calc = function(dataTable, row) {
columnFunction.#com.googlecode.gwt.charts.client.ColumnFunction::calc(Lcom/googlecode/gwt/charts/client/DataTable;I) (dataTable, row);
};
}-*/;
Was not returning the value calculated by the function, just calculating it.
Adding "return" to the line in the innermost block fixes the issue.
I am using dotnetrdf and trying to parse some triples with NTriplesParser. I have my own handler RobHandler in which I process each triple in turn.
public class RobHandler : BaseRdfHandler
{
protected override bool HandleTripleInternal(Triple t)
{
string predicateUrl = ((BaseUriNode)(t.Predicate)).Uri.AbsoluteUri;
string value = t.Object.ToString();
}
}
This works fine but I want to get the object minus the language. My objects look like "Lincoln"#en. I could obviously write some code to remove the #en bit, but I'd rather use some library code rather than my own that hard-coded strings like #en. To do this I think I need to create a LiteralNode but there doesn't seem to be a way to get from a string which is what I have (my variable value) to a LiteralNode.
How can I extract just the textual value from an object string?
Actually I think I have the answer myself:
if (t.Object.NodeType == NodeType.Literal)
{
var node = (ILiteralNode)t.Object;
}
I'm trying to create a chart who's yAxis is designed to show number of employee number, so it must only show whole numbers.
But I found it's not that easy as I already tried to yAxis.setTickUnit(1) but it won't work when the values are small(etc. the max value is 3, it'll still show 0.5,1.5..., I only want tick value like 1,2,3,4..)
How Could I to achieve this?
According to #jewelsea 's answer, I tried this(In javafx 2.2 jdk7)
class IntegerStringConverter extends StringConverter<Number>{
public IntegerStringConverter() {
}
#Override
public String toString(Number object) {
if(object.intValue()!=object.doubleValue())
return "";
return ""+(object.intValue());
}
#Override
public Number fromString(String string) {
Number val = Double.parseDouble(string);
return val.intValue();
}
}
It's result is kind of acceptable. Double value's are gone, but there ticks are still there.
Set a tickLabelFormatter on the axis.
You can set the NumberAxis(double lowerBound, double upperBound, double tickUnit) values by using the constructor. This works fine for JaxaFX 8, in case people like me are still looking for this.

Does anyone know of an Eclipse plug-in or method to get Eclipse to generate getter/setters on one line like this:
public String getAbc() { return abc; }
Instead of
public String getAbc() {
return abc;
}
I'm on Eclipse v. 3.2.2.
Thanks.
I don't know how to make Eclipse generate them in the format you want, but you could do a search/replace using these regular expressions after the methods are generated:
Find:
(?m)((?:public |private |protected )?[\w$]+) (get|set|is)([\w$]+)\(([\w$]+(?:\[\])? [\w$]+)?\) \{\s+(return [\w$]+;|this.[\w$]+ = [\w$]+;)\s+\}
Replace by:
$1 $2$3($4) { $5 }
This expression will transform the generated getters and setters to be one line. Don't worry about running it with a mixture of transformed and newly generated methods; it will work just fine.
I think matching generics is important as well, so the correct regexp is:
(?m)((?:public |private |protected )?[\w\<\>$]+) (get|set|is)([\w$]+)\(([\w\<\>$]+ [\w$]+)?\) \{\s+(return [\w$]+;|this.[\w$]+ = [\w$]+;)\s+\}
As a variation of the regexp replacement approach, the following reformats the whitespace so that setters are followed by a blank line, but getters are not.
Find:
(\s(?:get|is|set)\w+\([^)]*\))\s*\{\s*(?:([^=;}]+;)\s*\}\s*(\R)|([^=;}]+=[^=;}]+;)\s*\}\s*(\R))
Replace by:
$1 { $2$4 } \R$5
Results in:
int getTotal() { return total; }
void setTotal(int total) { this.total = total; }
List<String> getList() { return list; }
void setList(List<String> list) { this.list = list; }
Map.Entry<String, Integer> getEntry() { return entry; }
void setEntry(Map.Entry<String, Integer> entry) { this.entry = entry; }
It's a minor aesthetic thing, but I figured that if you're looking for an answer to this question, then you're probably (almost) as anal as me ;-)
I know my regexp conditions are not as strict as those of #Hosam, but I haven't experienced any "false positive" replacements.
Java code formatting in Eclipse does not differentiate between getters/setters and any other methods in a class. So this cannot be done by built-in eclipse formatting.
You will need either to:
run a search/replace with the aforementioned regex
get en external plugin like PMD or CheckStyle and enforce a regex rule based on previous option
You can use fast code plug-in to generate this kind of getter setters. The details are given here : http://fast-code.sourceforge.net/documentation.htm#create-new-field.
I wanted to post as a comment to the designated answer, but I don't seem to be able to.
I modified Hosam Aly's answer to work with generic and inner types of the form:
List<X>
and
Map.Entry
The revised regular expression search string is:
(?m)((?:public |private |protected )?[\w\.\<\>$]+) (get|set|is)([\w$]+)\(([\w\.\<\>$]+ [\w$]+)?\) \{\s+(return [\w\.\<\>$]+;|this.[\w$]+ = [\w$]+;)\s+\}
This regular expression allows for angle brackets and a dot in the type.
For example:
public List<String> getStringList()
and
public void setStringList(List<String> list)
and
public Map.Entry getEntry ()
And the replace string is the same as before:
$1 $2$3($4) { $5 }
