Hello all
I am using smart gwt 2.2 on windows with mozilla browser.
I am using a list grid with two fields.
I set the editor type of second field to SelectItem.
In that select item I am rendering a grid.
For select item I set the value field and the display field.
But after the select any item from select item it is display value field.
I am also attaching the code for it.
code for grid
public void initializeGrid() {
ListGrid grid = new ListGrid();
setGridProperty(grid);
grid.setFields(getGridFields());
grid.setData(getGridData());
getSmartContainer().addChild(grid);
}
private static ListGridRecord[] getGridData() {
ListGridRecord record = new ListGridRecord();
record.setAttribute("id", "");
record.setAttribute("name", "");
ListGridRecord record1 = new ListGridRecord();
record1.setAttribute("id", "");
record1.setAttribute("name", "");
return new ListGridRecord[] { record, record1 };
}
private static void setGridProperty(ListGrid grid) {
grid.setWidth("90%");
grid.setHeight(125);
grid.setCanEdit(true);
grid.setEditEvent(ListGridEditEvent.CLICK);
grid.setEditByCell(true);
grid.setAlternateRecordStyles(true);
grid.setShowAllRecords(true);
}
private static ListGridField[] getGridFields() {
ListGridField field = new ListGridField("id");
FormItem item = new TextItem();
field.setEditorType(item);
ListGridField field1 = new ListGridField("name");
SelectItem item1 = new SelectItem("name");
setPropertyForSelectitem(item1);
DataSource dataSource = new DataSource();
dataSource.setClientOnly(true);
item1.setOptionDataSource(dataSource);
setDataForSelectItem(dataSource);
field1.setEditorType(item1);
return new ListGridField[] { field, field1 };
}
Code for select item
public static void setDataForSelectItem(DataSource dataSource) {
for (int i = 0; i < 2; i++) {
ListGridRecord record = new ListGridRecord();
record.setAttribute("id", "1");
record.setAttribute("name", "name" + i);
record.setAttribute("address", "address" + i);
dataSource.addData(record);
}
}
private static void setPropertyForSelectitem(SelectItem item) {
item.setPickListFields(getFieldsForSelectItem());
item.setWidth(150);
item.setValueField("id");
item.setDisplayField("name");
item.setPickListWidth(250);
}
private static ListGridField[] getFieldsForSelectItem() {
ListGridField idField = new ListGridField("id");
ListGridField nameField = new ListGridField("name");
ListGridField addField = new ListGridField("address");
return new ListGridField[] {idField,nameField,addField };
}
[/CODE]
After drawing this grid it is rendering value field for the select item, but i want to render the name (as it is the display field for the select item).
Same select item I used in the dynamic form but it is working well at that place, but for the grid it is not working well.
Please Help.
Thanks

Activity 1 sends the info I want to Activity 2:
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> listView, View view,
int position, long id)
{
// Get the cursor, positioned to the corresponding row in the result set
Cursor cursor = (Cursor) listView.getItemAtPosition(position);
final int item_id = cursor.getInt(cursor.getColumnIndex(GamesDbAdapter.KEY_ROWID));
String item_cursus = cursor.getString(cursor.getColumnIndex(GamesDbAdapter.KEY_CURSUS));
String item_onderdeel = cursor.getString(cursor.getColumnIndex(GamesDbAdapter.KEY_ONDERDEEL));
String item_tijd = cursor.getString(cursor.getColumnIndex(GamesDbAdapter.KEY_TIJD));
String item_game = cursor.getString(cursor.getColumnIndex(GamesDbAdapter.KEY_GAME));
String item_web = cursor.getString(cursor.getColumnIndex(GamesDbAdapter.KEY_WEB));
Intent intent = new Intent(actGames_FRONT_ListViewCursorAdaptorActivity.this, actGames_ALL_ListViewCursorAdaptorActivity.class);
intent.putExtra("cursus", item_cursus);
intent.putExtra("id", item_id);
intent.putExtra("game", item_game);
startActivity(intent);
Toast done =
Toast.makeText(getApplicationContext(), item_game, Toast.LENGTH_LONG);
done.show();
}
});
In Activity2 I want to display "game" in another listview, but setText doesn't work with Listview.
game = (TextView)findViewById(R.id.game);
Intent iin= getIntent();
Bundle c = iin.getExtras();
if(c!=null)
{
String item_game =(String) c.get("game");
game.setText(item_game);
}
String game_list = getIntent().getExtras().getString("game");
This is the simplecursoradapter in activity2:
private void displayListView() {
Cursor cursor = dbHelper.fetchAllCursus();
// The desired columns to be bound
String[] cursus = new String[] {
GamesDbAdapter.KEY_CURSUS,
};
// the XML defined views which the data will be bound to
int[] to = new int[] {
R.id.front,
};
// create the adapter using the cursor pointing to the desired data
//as well as the layout information
dataAdapter = new SimpleCursorAdapter(
this, R.layout.games_row_front,
cursor,
cursus,
to,
0);
ListView listView = (ListView) findViewById(R.id.listView1);
// Assign adapter to ListView
listView.setAdapter(dataAdapter);
And this is in my DBadapter:
public Cursor fetchGames(){
String[] args = {"********************" };
Cursor mCursor = mDb.query(SQLITE_TABLE, null,
"cursus = ?" , args, KEY_GAME, null, null);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor;
}
When I replace the *** with a static item from the database it works but I can't get it to work with the intent from the first activity. Is there a way to fill a listview with info from another listview in another activity?
I use ListGrid without datasource. And I use validator for some fields.
But then I add new record, it is not validated till I change value in new record.
I don't want to use grid.startEditingNew(), because if I don't change them, they do not have Record instance.
ListGrid grid = new ListGrid();
grid.setCanEdit(true);
ListGridField field1 = new ListGridField("attr1", "Name1");
ListGridField field2 = new ListGridField("attr2", "Name2");
CustomValidator validator = new CustomValidator() {
#Override
protected boolean condition(Object value) {
Logger.log("Validate: " + value);
return true;
}
};
field1.setValidators(validator);
field2.setValidators(validator);
grid.setFields(field1, field2);
Label addButton = new Label();
//...
addButton.setTooltip("Add");
addButton.addClickHandler(new ClickHandler() {
public void onClick(final ClickEvent clickEvent) {
ListGridRecord record = new ListGridRecord();
grid.addData(record);
// we can use grid.startEditingNew() instead
}
});
How I can force validation of the new row? Calling grid.validateRow(grid.getRecords().length - 1) do not lead to calling the validatior.
Why not validate values being set to the new Record instance (from FormItems?) instead?
You can reuse validators on ListGridField and FormItem.
I want to place a "Next" button which , when clicked , will display another group of components ; and I want also to place a "Previous" button which , when clicked , then display the previous group of components. How to achieve that ?
I recently implemented forms for data entry. Typically i have a wizard class that holds all the forms in the wizard, so i can easily navigate back and forth between them. And when i call a new form, i pass along the object of the wizard.
Below is my wizard, with implementation omitted.
public final class ReportWizard {
public static ReportWizard instance = null;
Form parent = null;
Form titleForm = null;
Form budgetForm = null;
Form iconForm = null;
final Report reports[] = new Report[20];
public ReportWizard(Form parent) {
this.parent = parent;
this.instance = this;
}
void getTitle() {
AddReportForm reportForm = new AddReportForm(parent, this);
reportForm.showReportForm();
titleForm = reportForm;
ImageListPicker getIcon = new ImageListPicker(titleForm, reports, this);
iconForm = getIcon.imageListForm;
}
void getIcon() {
iconForm.show();
}
public void cancelWizard() {
titleForm = null;
iconForm = null;
budgetForm = null;
instance = null;
parent.show();
parent = null;
System.gc();
}
}
I'm trying to set the selected records of a ListGrid table object in SmartGWT using records, but I can't find any way of doing it. I want to select with record, not index. I want to use selectRecord(Record record) method.
As an example;
public void onModuleLoad()
{
VLayout main = new VLayout();
final ListGrid grid = new ListGrid();
grid.setHeight(500);
grid.setWidth(400);
grid.setFields(new ListGridField("name", "Name"));
grid.setData(createRecords());
final IButton button = new IButton("Select some");
button.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event)
{
grid.selectRecord(createRecord("orange"));
}
});
main.addMember(grid);
main.addMember(button);
RootPanel.get().add(main);
}
private ListGridRecord[] createRecords()
{
return new ListGridRecord[]{
createRecord("monkey"),
createRecord("banana"),
createRecord("orange"),
createRecord("sun")
};
}
private ListGridRecord createRecord(String name)
{
ListGridRecord record = new ListGridRecord();
record.setAttribute("name", name);
return record;
}
In this case I want to select orange, But this code select anything.
Is it posible? If possible how?
Thanks in advance.
Found this solution;
selectRecord(grid.getRecordList().find("name", "orange"));
There's a problem with your code:
When you write
grid.selectRecord(record);
it goes to search the same record instance that the grid has. If both instances of record are equal, only then & then it selects the record. Otherwise nothing happens as you're facing right now. Here what you need to do is:
ListGridRecord[] records = countryGrid.getRecords();
int i;
for (i = 0; i < records.length; i++)
{
if (records[i].getAttribute("name").equalsIgnoreCase("orange"))
{
break;
}
}
countryGrid.selectRecord(i);
I'm trying to set the selected records of a ListGrid table object in SmartGWT, but I can't find any way of doing it. I know there's a getSelectedRecords() function, but no matching setSelectedRecords(). I tried to see if set/getSelectedState() would work, but GWT complains about needing a primary key and a DataSource object. Is there any way to set the selection of a ListGrid?
For this you can use one of the selectRecords() methods, like so:
public void onModuleLoad()
{
VLayout main = new VLayout();
final ListGrid grid = new ListGrid();
grid.setHeight(500);
grid.setWidth(400);
grid.setFields(new ListGridField("name", "Name"));
grid.setData(createRecords());
final IButton button = new IButton("Select some");
button.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event)
{
grid.selectRecords(new int[]{2, 3}); //This will select index 2 and 3
}
});
main.addMember(grid);
main.addMember(button);
RootPanel.get().add(main);
}
private ListGridRecord[] createRecords()
{
return new ListGridRecord[]{
createRecord("monkey"),
createRecord("banana"),
createRecord("orange"),
createRecord("sun")
};
}
private ListGridRecord createRecord(String name)
{
ListGridRecord record = new ListGridRecord();
record.setAttribute("name", name);
return record;
}
