Defining my own Filter-Field

Hello

 

I'd like to have a Filter-Combobox for my DataTable row which has numbers as data. Is it possible to have combobox-entries like:

in my "String-row" ?

 

Thanks for help

Re: Defining my own Filter-Field

Hello,

 

Yes, you can specify a function that will return the number ranges. Here is an example with part of JSP page:

 

<q:dataTable var="person" 
               value="#{PeopleList.person}"
               rowKey="#{person.id}">
    <q:column filterExpression="#{person.name}"
              filterKind="searchField">
      <f:facet name="header">
        <h:outputText value="Name" ></h:outputText>
      </f:facet>
      <h:outputText value="#{person.name}" ></h:outputText>
    </q:column>
    <q:column filterExpression="#{PeopleList.personAgeRange}" filterKind="comboBox">
      <f:facet name="header">
        <h:outputText value="Age"></h:outputText>
      </f:facet>
      <h:outputText value="#{person.age}" ></h:outputText>
    </q:column>
  </q:dataTable>

 

And getPersonAgeRange() method from “PeopleList” backing bean:

 

public String getPersonAgeRange() {

    Person person = (Person) FacesUtil.getRequestMapValue("person");
    int age = person.getAge();
    if (age <= 10)
      return "0-10";
    if (age <= 20)
      return "11-20";
    if (age <= 30)
      return "21-30";
    if (age <= 40)
      return "31-40";
    return ">40";
  }

Currently, you cannot directly delete entries from the filter field. If there is at least one empty cell in the column, these entries will be added automatically. You can only change text for these entries. We will consider providing an option to hide these entries.

 

Regards,

Tatyana

Re: Defining my own Filter-Field

Hi Tatyana

 

Thanks a lot! It's exactly what I'm looking for.

 

I have 2 other questions regarding Filterboxes:

-How can I define the width of a filter-box?

 

- Is there a possibility to influence the order of the above ComboBox items. E.g.

if I wonna have:

<-300%

-299% to -200%

-199% to -100%

>-100%

 

and not

 

-199% to -100%

-299% to -200%

>-100%

<-300%

 

Thanks

Re: Defining my own Filter-Field

You cannot explicitly change the width of a filter field. Its width is equal to the column width. You can change the column width with the “style” attribute of the <q:column> tag.

Re: Defining my own Filter-Field

You can use filterValues attribute to retrieve list of filter values in order you need. Here is an example:

 

..
<q:column filterExpression="#{PeopleList.personAgeRange}"      filterKind="comboBox"
                 filterValues="#{PeopleList.ageRanges}">
      <f:facet name="header">
        <h:outputText value="Age"></h:outputText>
      </f:facet>
      <h:outputText value="#{person.age}" ></h:outputText>
 </q:column>
..

 

And method from “PeopleList” backing bean:

 

  public List getAgeRanges(){
    myAgeRanges.add(">40");
    myAgeRanges.add("31-40");
    myAgeRanges.add("21-30");
    myAgeRanges.add("11-20");
    myAgeRanges.add("0-10");

    return myAgeRanges;
  }

Re: Defining my own Filter-Field

Thanks for your answer. Unfortunately, I still get it in the wrong order:

 

In my Backing-Bean:

 

    public String getReturnRange() {

       myType node = (myType) FacesUtil.getRequestMapValue("results");

        double ret = node.getReturn();

        if (ret 30%");

        return myReturnRanges;

    }

 

The ComboBox items are in this wrong order:

 

10% bis 20%

0% bis 10%

< 0%

30%

20% bis 30%

 

What did I wrong?

 

Cheers,

Re: Defining my own Filter-Field

Hello,

 

Yes, you are right. It was my mistake, in the current version of the QuipuKit library there is no possibility to change the order of entries in the filter field. But we will provide it in one of our next minor updates of QuipuKit.

 

Regards,

Tatyana
