I'm trying to make editable a table view dynamic in javaFX, i already have the dynamic table loading values from a object and works perfect, but i can't make this editable.
i create the dinamic table with this
ArrayList<reportes> rs = BD.ConsultarVarios(selecionado);
for (int column = 1; column +1< rs.size(); column++) {
tablevarios.getColumns().add(
createColumn(column, rs.get(column).getNombre()));
}
// Add data to table:
ArrayList<ObservableList<StringProperty>> data = new ArrayList<>(FXCollections.observableArrayList());
for (int i = 0; rs.get(0).getValor().size() > i; i++) {
ObservableList<StringProperty> data2 = FXCollections.observableArrayList();
for (int k = 0; rs.size() > k+1; k++) {
data2.add(new SimpleStringProperty(rs.get(k).getValor().get(i)));
}
data.add(data2);
tablevarios.getItems().add(data.get(i));
}
but when i try to make editable with this
tablevarios.getColumns().get(i).setCellFactory(column -> new EditCell());
i have this error from the console
Error:(1687, 78) java: incompatible types: bad return type in lambda expression
sample.Main.EditCell cannot be converted to javafx.scene.control.TableCell,capture#1 of ?>
thanks for the help
Does your EditCell extends ListCell ?
I did it in my project like this:
class EditCell extends ListCell<?> {
// your cell properties here
#Override
protected void updateItem(Object item, boolean empty) {
super.updateItem(item, empty);
}
tablevarios.getColumns().get(i).setCellFactory(lv -> {
ListCell<?> cell = new EditCell();
//maybe add context menu to cell or other thins
return cell;
}

I want to loop through columns(fields) in grid control in AX 2012 form. I have this logic to loop through fields :
static void Job1(Args _args)
{
SysDictTable dictTable = new SysDictTable(tableNum(PurchLine));
SysDictField dictField;
TreeNode treeNode;
FieldId fieldId = dictTable.fieldNext(0);
while (fieldId)
{
dictField = dictTable.fieldObject(fieldId);
if (dictField.isSql() && !dictField.isSystem())
{
treeNode = dictField.treeNode();
info(strFmt("%1 | %2 | %3",
dictField.name(), // Field name
treeNode.AOTgetProperty("Label"), // Label id
SysLabel::labelId2String(treeNode.AOTgetProperty("Label")))); // Label string
}
fieldId = dictTable.fieldNext(fieldId);
}
}
This loop through table, I need similar logic to loop through grid fields but in RUNTIME.
For example if grid data source has 5 columns and 3 are removed in UI, i want to loop just through these 2 that are left in the grid.
So my question is how to get grid fields in runtime( not from datasource table) ?
The below assumes your grid is named "GridOverview". You call it like:
::outputGridControls(element) where element is your form.
public static void outputGridControls(FormRun _formRun)
{
int i;
FormGridControl formGridControl;
FormControl formControl;
formGridControl = _formRun.control(_formRun.controlId(identifierStr(GridOverview)));
if (formGridControl)
{
for (i=1; i<=formGridControl.controlCount(); i++)
{
formControl = formGridControl.controlNum(i);
if (formControl && formControl.visible())
{
info(strFmt("%1 (%2)", formControl.name(), formControl.labelText()));
}
}
}
}
What you're doing above is reflecting on the AOT table, but you need to be looking at the FormRun and not the actual table or even the DataSource.
I am trying loop through all the ComboBoxinstances I made in order to get the value the user picks and add that value to a new ArrayList, but I am stuck on how to proceed making the loop to get the values.
// row for comboboxes
HBox numBox = new HBox();
numBox.setSpacing(16);
numBox.setAlignment(Pos.CENTER);
vbox.getChildren().add(numBox);
// setup loop to create 8 combo boxes for user to pick
int comboNum = 8;
ComboBox<Integer> binaryBox = new ComboBox<Integer>();
for (int i = 0; i < comboNum; i++) {
binaryBox = new ComboBox<Integer>();
List<Integer> binaryList = new ArrayList<Integer>();
binaryList.add(0);
binaryList.add(1);
for (Integer num : binaryList) {
binaryBox.getItems().addAll(num);
}
binaryBox.setValue(0);
numBox.getChildren().add(binaryBox);
}
// way to get the value from each combo box
ChangeListener<Number> update =
(ObservableValue <? extends Number> ov, Number oldValue, Number newValue) -> {
for (int i = 0; i < comboNum; i++){
//todo
}
};
Each ComboBox has a SelectionModel from which you can obtain the selectedItem. First, create a list of combo boxes and populate it with your instances of ComboBox<Integer>:
List<ComboBox<Integer>> list = new ArrayList<>();
for (int i = 0; i < comboNum; i++) {
ComboBox<Integer> binaryBox = new ComboBox<Integer>();
list.add(binaryBox);
…
}
Later, you can loop through the list to retrieve the selected items using getSelectedItem():
for (ComboBox<Integer> combo : list) {
System.out.println(combo.getSelectionModel().getSelectedItem());
}
I'm using tutorial_Form_Table.
The table has dynamically assigned values, something like:
for (col = 1; col <= 5; col++)
{
for (row = 1; row <= 5; row++)
{
if ((col == 2) || (col == 4))
{
if (row > 1)
table.cell(col,row).data(row*col);
else
table.cell(col,row).data("Text "+int2str(row*col));
}
else
table.cell(col,row).data("Text "+int2str(row*col));
}
}
I need to get the position of the cell when I enter new value in it, so I can update the corresponding table with the value entered.
Thank you.
Table has two properties: row() and column() which return values of current active cell.
public void activeCellChanged()
{
super();
info(strFmt('%1 %2 %3', Table.row(), Table.column(), Table.cell(Table.column(), Table.row()).data()));
}
On each of the controls you add to the table control you can override the modified method to see the new value you entered.
public boolean modified()
{
boolean ret;
ret = super();
info(strFmt('New data that we need to save: %1, %2 -> %3', Table.row(), Table.column(), Table.cell(Table.column(), Table.row()).data()));
return ret;
}
If you are working with a lot of data you should consider using some other control such as .NET grid control because of performance issues.
I am making a shopping cart type of thing using grid view user will keep adding item in it after doing it so user will click save i want to get values from all columns of grid view each row at a time and save it to database.
here is the code for grid view load
protected void add_Click(object sender, EventArgs e)
{
product.Item = Item_Drop.SelectedItem.Text;
product.Quantity = quantity_box.Text;
int qun =Convert.ToInt32(quantity_box.Text);
int unitP= Convert.ToInt32(unitPrice_box.Text);
product.item_Toal = (qun*unitP).ToString();
list.Add(product);
temp_gridView.DataSource = list;
temp_gridView.DataBind();
}
And here is what i am trying to get values
public void Values_from_grid()
{
foreach(temp_gridView row in temp_gridView.Rows)
{
for(int i = 0; i < temp_gridView.Columns.Count, i++)
{
String header = temp_gridView.Columns[i].HeaderText;
String cellText = row.Cells[i].Text;
}
}
}
i am not getting any values in "header" or "cellText" . .. .
Use this code to get header row value .
GridViewName.HeaderRow.Cells[0].Text;
Found Answer no need to use
GridView.Rows.Count
just use a simple int to iterate
int i = 0;
foreach(GridViewRow row in temp_gridView.Rows)
{
box.Item_id = temp_gridView.Rows[i].Cells[0].Text;
box.Quantity = temp_gridView.Rows[i].Cells[1].Text;
box.Total = temp_gridView.Rows[i].Cells[2].Text;
i++;
}
How to add margins to the grid elements in grid manager layout of blackberry.I want it to appear exactly like it looks on a sqlite table with rows and columns having neat margins.Also i would like to add color to each row of the grid.The elements in the grid have been fetched from sqlite table string by string.
I have the following code:
GridFieldManager grid = new GridFieldManager(10,5,0);
grid.add(new LabelField("Date"));
grid.add(new LabelField("Bill"));
grid.add(new LabelField("Receipt"));
grid.add(new LabelField("Narration"));
grid.add(new LabelField("ID"));
grid.setColumnPadding(15);
grid.setRowPadding(20);
for (int i = 1; i < grid.getRowCount(); i++) {
System.out.println("Inside for first loops");
for (int j = 0; j < grid.getColumnCount() ; j++) {
System.out.println("Inside for second loops");
while(c.next()) {
System.out.println("Inside while");
Row r;
r = c.getRow();
for (int k = 4; k >=0; k--) {
System.out.println("Inside for loops");
if(k==0 || k==3) {
System.out.println("Retrieving date or narration");
grid.insert(new LabelField(r.getString(k)) {
public void paint(Graphics graphics) {
graphics.setColor(Color.BROWN);
super.paint(graphics);
}
},i,j);
} else {
System.out.println("Retrieving other values");
String p = "" + r.getInteger(k);
grid.insert(new LabelField(p) {
public void paint(Graphics graphics) {
graphics.setColor(Color.BROWN);
super.paint(graphics);
}
},i,j);
}
grid.setBackground(
BackgroundFactory.createLinearGradientBackground(
Color.GOLD,Color.CHOCOLATE,Color.GOLDENROD,Color.CORAL));
}
System.out.println("Exiting while");
}
System.out.println("Exiting sec for");
break;
}
System.out.println("Exiting first for");
break;
}
With the above code I am getting a linear gradient background color being applied to the whole screen. Also the elements of the grid excluding the headings are in brown color.
What I now want to achieve is separate colors for each row.
Anyone aware on the solution to this please share. Thanks.
To add color to the fetched rows you could use this code:
for (int k = 4; k >=0; k--)
{
System.out.println("Inside for loops");
//Check for whether column retrieved is date or naraation
if(k==0 || k==3)
{
System.out.println("Retrieving date or narration");
grid.insert(new LabelField(r.getString(k))
{
public void paint(Graphics graphics)
{
graphics.setColor(Color.GOLD);
super.paint(graphics);
}
},i,j);
}
else
{
//Check for whether column retrieved is bills,rec or id
System.out.println("Retrieving other values");
String p = "" + r.getObject(k);
//if(r.getString(k) != null)
//{
grid.insert(new LabelField(p)
{
public void paint(Graphics graphics)
{
graphics.setColor(Color.GOLD);
super.paint(graphics);
}
},i,j);
// }
}
Using it in if else manner may help your solution.
You can achieve the color part in two ways:
Override the grid manager paint method (difficult)
Add a custom VerticalFieldManager containing exactly one label field to each cell, instead of adding the labelfield directly. This is the easiest approach IMHO.
