Hi,
My intention is that when i make a long press on an element there should be
displayed a warning message and then remove the element.
At first put the code of the long press on the component "lead" but does
nothing.
The problem is that to trigger the long press I had to place the code on
the creation of the new container (at Steve's suggestion); When I place the
remove method it tells me that the container has to be initialized.
My Code:
*The "creaContenedorCompra2" method returns the container array.*
private Container creaContenedorCompra2(Form fmCompra2, Compra1 cR1) {
Container cnCompras = new Container();
cnCompras.setScrollableY(true);
Vector vCompra2 = dT.getCompra2(cR1);
for (int i = 0; i < vCompra2.size(); i++) {
Compra2 cR2 = (Compra2) vCompra2.elementAt(i);
cnCompras.add(creaContenedorItemCompra2(fmCompra2, cR1, cR2));
}
cnCompras.revalidate();
return cnCompras;
}
*The "*creaContenedorItemCompra2*" method returns an element that will be
part of the container array*
private Container creaContenedorItemCompra2(Form fmCompra2, Compra1
cR1, Compra2 cR2) {
Container cnCompra = new Container() {
@Override
public void longPointerPress(int x, int y) {
super.longPointerPress(x, y);
Dialog dlg = new Dialog();
dlg.setUIID("Label");
boolean continuar = dlg.show(idioma.getMensaje19(),
idioma.getMensaje13(), idioma.getSi(), idioma.getNo());
if (continuar) {
// cnCompra.remove(); *Show
message "Initialize variable cnCompra"*
cR2.setCondicion(Constantes.REGISTRO_ELIMINADO);
cR2.setSincronizado(false);
Vector vCompra2 = dT.getCompra2(cR1);
for (int i = 0; i < vCompra2.size(); i++) {
Compra2 cR = (Compra2) vCompra2.elementAt(i);
if (cR.getCompra().equals(cR2.getCompra()) &&
cR.getArticulo().equals(cR2.getArticulo())) {
vCompra2.setElementAt(cR2, i);
}
}
}
}
