I have a structure with combo-box, and those combo-box
has the following form:
Municipios is Cities in english.
public Store createMunicipiosStore() {
Object[][] municipios = this.getMunicipiosDoBD();
//id_municipio,id_subbacia,id_bacia,nome_municipio
final Store municipiosStore = new SimpleStore(new String[] {
MUNICIPIO_ID, SUBBACIA_ID, BACIA_ID, NOME_MUNICIPIO },
municipios);
municipiosStore.load();
return municipiosStore;
}
The data are stored in an array of Object. And there Listeners to link
filter and a combo-box from another.
In this case:
Combo box1 = Municipios (Cities)
Combo = box2 Postos (Locations)
But the filtering is being done in the style starswith(similar the String
API), it is as if he were a starswith in the code of the object.
type, if the code (ID) of the minicipio(City) is (1) in the list of posts
will also appear that the posts have counties with codes 10, 11, 12 etc.
public Store createPostoStore() {
Object[][] postos = this.getPostosDoBD();
final Store postosStore = new SimpleStore(new String[] { POSTO_ID,
MUNICIPIO_ID, SUBBACIA_ID, BACIA_ID, NOME_POSTO }, postos);
postosStore.load();
return postosStore;
}
public Store createMunicipiosStore() {
Object[][] municipios = this.getMunicipiosDoBD();
//id_municipio,id_subbacia,id_bacia,nome_municipio
final Store municipiosStore = new SimpleStore(new String[] {
MUNICIPIO_ID, SUBBACIA_ID, BACIA_ID, NOME_MUNICIPIO },
municipios);
municipiosStore.load();
return municipiosStore;
}
And the listener to link and filter is:
CBMunicipio.addListener(this.createListenerAdapter(CBPostoDoMunicipio,
postoDoMunicipioStore, MUNICIPIO_ID));
public ComboBoxListenerAdapter createListenerAdapter(
final ComboBox combBox, final Store store, final String id) {
ComboBoxListenerAdapter listener = new ComboBoxListenerAdapter() {
public void onSelect(ComboBox comboBox, Record record, int
index) {
combBox.setValue("");
store.filter(id, comboBox.getValue());
}
};
return listener;
}
The codes (IDS) of both minicipios(City) as the postos(locations) are
integers.
Thank you for the attention.
