Hi,
Sorry for my english.
I have a set of containers that move vertically efficiently.
To create a new container I use a floating button without problem.
To remove a container my idea was to make a long press on the container and
proceed to remove the container but I do not know how to do it.
To change the contents of a container my idea was to press on the container
and open a form with the information of the container and accepting to pass
the updated information returned to the container (I imagine with the
method replace). I have no problem in making the form and loading the
information but as to which container pass the information or do the
replace.
Would appreciate an example
*My code to create the container set and search is:*
Container cnCompras = new Container();
cnCompras.setScrollableY(true);
Vector vCompra2 = dT.getCompra2(cR1);
for (int i = 0; i < vCompra2.size(); i++) {
Compra2 lR2 = (Compra2) vCompra2.elementAt(i);
cnCompras.addComponent(creaContenedorCompra2(fmCompra2, cR1,
cR2));
}
txBusqueda.addDataChangeListener(new DataChangedListener() {
public void dataChanged(int type, int index) {
String t = txBusqueda.getText();
if (t.length() < 1) {
for (Component cmp : cnCompras) {
cmp.setHidden(false);
cmp.setVisible(true);
}
} else {
t = t.toLowerCase();
for (Component cmp : cnCompras) {
boolean show = false;
String val = null;
if (cmp instanceof Container) {
val = (String)
cmp5.getPropertyValue("busqueda");
}
show = val != null && val.toLowerCase().indexOf(t)
> -1;
cmp.setHidden(!show);
cmp.setVisible(show);
}
}
cnCompras.animateLayout(250);
}
}
);
*The "creaContenedorCompra2" method has the following code:*
private Container creaContenedorCompra2(Form fmCompra2, Compra1 lR1,
Compra2 lR2) {
TextArea articulo = new TextArea(2, 70);
Label lbCantidad = new Label();
Label lbPrecio = new Label();
Label lbMonto = new Label();
Label lbUM = new Label();
TextArea cantidad = new TextArea();
TextArea precio = new TextArea();
TextArea monto = new TextArea();
TextArea uM = new TextArea(1, 7);
articulo.setUIID("MultiLine2");
articulo.setFocusable(true);
articulo.setEditable(false);
articulo.setAlignment(TextArea.LEFT);
articulo.setPropertyValue("serial", lR2.getSerial());
lbCantidad.setText(idioma.getCantidad() + ":");
lbCantidad.setUIID("MultiLine3");
cantidad.setUIID("MultiLine3");
cantidad.setFocusable(true);
cantidad.setEnabled(true);
lbPrecio.setText(idioma.getPrecio() + ":");
lbPrecio.setUIID("MultiLine3");

lbUM.setText(idioma.getUM() + ":");
lbUM.setUIID("MultiLine3");
uM.setUIID("MultiLine3");
uM.setFocusable(true);
uM.setEnabled(true);
Button lbImagen = new Button() {
@Override
public void longPointerPress(int x, int y) {
super.longPointerPress(x, y);
*// * * Delete Container *
}
@Override
public void addActionListener(ActionListener l) {
super.addActionListener(l); //To change body of generated
methods, choose Tools | Templates.

accepting passes the information of the form to container.*
}
};
lbImagen.setUIID("TransparentButton");
articulo.setText(lR2.getNombreArticulo());
uM.setText(lR2.getUnidadMedida());
Double cnt = lR2.getCantidad();
Double pre = lR2.getPrecio();
