I'm working on a SWT GUI and I'm trying to create a button that on press clear all table data and the headers.
table.removeAll();
This command don't work well because it's removing only the data inside and I need to remove the table headers too.
Is there a solution?
EDIT: after the code to clear the header worked, if I try to add new file with data, the header go to the next point. why if it blank? (the ArrayLists that contains the header names cleared too).
First image is when first file uploaded, after click on "Start" button the data shown on table:
Second image is after the table cleared all data by pressing on another button:
Third image is after uploading new file and press "Start" button:
EDIT: Headers Set
tableConfigurationSystemColumnTools.add("Parameter Name");
for (String str : tableSystemColumn) {
String[] a = str.split("PCM");
tableConfigurationSystemColumnTools.add(a[0].trim());
}
for (int loopIndexSystemColumnTools = 0;
loopIndexSystemColumnTools < tableConfigurationSystemColumnTools.size(); loopIndexSystemColumnTools++) {
TableColumn column = new TableColumn(tableConfigurationSystem, SWT.NULL);
column.setWidth(100);
column.setText(tableConfigurationSystemColumnTools.get(loopIndexSystemColumnTools));
}
for (int loopIndexSystemColumnTools = 0; loopIndexSystemColumnTools < tableConfigurationSystemColumnTools.size(); loopIndexSystemColumnTools++) {
tableConfigurationSystem.getColumn(loopIndexSystemColumnTools).pack();
}
EDIT: I've founded the answer, look at my comment.
button.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
table.removeAll();
TableColumn[] columns = table.getColumns();
for (int i = 0; i < columns.length; i++) {
columns[i].setText("");
}
}
});
I founded the answer - in the "for" loop that creating TableColumn, I'v added "index":
TableColumn column = new TableColumn(tableConfigurationSystem, SWT.NONE, loopIndexSystemColumnTools);
this is working.
Thank you guys.

I have the problem with the following code:
XWPFTable table = <get table somehow>;
CTRow firstRow = table.getRow(0).getCtRow();
for (int i = 0; i < data.getRowCount(); i++) {
CTRow ctRow = (CTRow) firstRow.copy();
XWPFTableRow row = new XWPFTableRow(ctRow, table);
XWPFRun[] cellRuns = row.getTableCells()
.stream()
.map(c -> c.getParagraphs().get(0))
.map(p -> p.getRuns().isEmpty() ? p.createRun() : p.getRuns().get(0))
.toArray(XWPFRun[]::new);
for (int j = 0; j < cellRuns.length; j++) {
cellRuns[j].setText(data.getValueAt(i, j).toString(), 0);
}
table.addRow(row);
}
table.getRow(1).getTableCells()
.get(0).getParagraphs()
.get(0).getRuns()
.get(0).setText("FooBar", 0); //change text in some added row
This code is copying the first row of the table several times and then copying values from data. Works perfectly fine (except text style) except the last operator, which was supposed to change the text in some added table row. Also, the "FooBar" string doesn't even appear in document.xml of created WORD document. I failed to see any clues from debug, because it seems, that table.addRow(row); operator just copies row pointer to it's internal list of rows. Also, I didn't have problems with altering already existing rows. So do you have any ideas why this could happen?
To reproducing the problem do having a source.docx having a first table having at least two rows.
Then do running following code:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTRow;
public class WordInsertTableRow {
static XWPFTableRow insertNewTableRow(XWPFTableRow sourceTableRow, int pos) throws Exception {
XWPFTable table = sourceTableRow.getTable();
CTRow newCTRrow = CTRow.Factory.parse(sourceTableRow.getCtRow().newInputStream());
XWPFTableRow tableRow = new XWPFTableRow(newCTRrow, table);
table.addRow(tableRow, pos);
return tableRow;
}
static void commitTableRows(XWPFTable table) {
int rowNr = 0;
for (XWPFTableRow tableRow : table.getRows()) {
table.getCTTbl().setTrArray(rowNr++, tableRow.getCtRow());
}
}
public static void main(String[] args) throws Exception {
XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));
boolean weMustCommitTableRows = false;
XWPFTable table = doc.getTableArray(0);
// insert new row, which is a copy of row 2, as new row 3:
XWPFTableRow sourceTableRow = table.getRow(1);
XWPFTableRow newRow3 = insertNewTableRow(sourceTableRow, 2);
// now changing something in that new row:
int i = 1;
for (XWPFTableCell cell : newRow3.getTableCells()) {
for (XWPFParagraph paragraph : cell.getParagraphs()) {
for (XWPFRun run : paragraph.getRuns()) {
run.setText("New row 3 run " + i++, 0);
}
}
}
System.out.println(newRow3.getCtRow()); // was changed
System.out.println(table.getRow(2).getCtRow()); // even this is changed
System.out.println(table.getCTTbl().getTrArray(2)); // but this was not changed, why not?
weMustCommitTableRows = true;
if (weMustCommitTableRows) commitTableRows(table); // now it is changed
FileOutputStream out = new FileOutputStream("result.docx");
doc.write(out);
out.close();
doc.close();
}
}
This code creates a copy of second row and inserts it as third row in the table. Then it does changing something in that new third row.
The issue ist, that the changings do appearing in low level CTRow of the row itself but do not appearing in low Level CTTbl of the table. For me this is not logically and I cannot get the reason of that. It looks as if the new CTRow elements are not part of the CTTbl at all. But they were added to it using ctTbl.setTrArray in XWPFTable.addRow. So I suspect there is something wrong with setTrArray in org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTbl. It seems updating the XML correctly but losing the object relations in the array (or list) of CTRows in CTTbl. But this is very hard to determining because of the kind of programming the org.openxmlformats.schemas classes. At least I was not able to do so. Maybe another of the professional and enthusiast programmers here may be able?
I am using the same approach for inserting rows having tthe same styling as a given source row. But after I have done this, I am setting boolean weMustCommitTableRows = true; and then I am doing if (weMustCommitTableRows) commitTableRows(table); before writing out the document. Then all changings will be committed.
I would like to get value from cell when its is no submitted (cell is in edit mode) - "real time"; Is it possible?
I tried this but it is working only if i submit data - press enter
int row = jTable.getSelectedRow();
int col = jTable.getSelectedColumn();
String cellValue = jTable.getValueAt(row, col).toString();
I want to get on keypress cell value without exiting it, get this text real time while typing
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher() {
#Override
public boolean dispatchKeyEvent(KeyEvent e) {
int row = jTable.getSelectedRow();
int col = jTable.getSelectedColumn();
if (e.getID() == KeyEvent.KEY_RELEASED) {
if (jTable.isEditing())
jTable.getCellEditor().stopCellEditing();
String cellValue = (jTable.getValueAt(row, col)!=null) ? jTable.getValueAt(row, col).toString() : "";
System.out.println(cellValue);
}}
jTable.getCellEditor().stopCellEditing() - cause ugly in/out animation while typing
#camickr Sorry for the confusion. Your solution is ok.
I just needed to add jTable.editCellAt(row, col); to get back into edit mode.
Thanks again
cell is in edit mode
The editing must be stopped before the value is saved to the model.
The easiest way to do this is to use:
JTable table = new JTable(...);
table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
when you create the table.
Now when you click on the button to do your processing the table loses focus so the data is saved.
Check out Table Stop Editing for more information.
i currently able to select a row of table using ListSelectionModel object and open a new window. but if i close that window and click that row again, it would not open anymore until i select another row of table (i can't select a row for a second time). do you know how can i solve this issue ?
this is what i have done:
ListSelectionModel model = table.getSelectionModel();
model.addListSelectionListener(new ListSelectionListener(){
public void valueChanged(ListSelectionEvent e)
{
if(!model.getValueIsAdjusting())
{
int row = model.getMinSelectionIndex();
//new Window opens :
SubjectDetail sd = new SubjectDetail(Datalist2.project.listOfData().get(row));
}
}
});
The selection is not working because that particular row is already selected.
Try clearing the selection when a new window is opened.
table.getSelectionModel().clearSelection().
I am working with apose words java recently.
In my first page I have a table need to merge, which can grow any size, no fixed number of rows and at the end of my first page, I want to keep some content (for example contact details) to be fixed. (Note: I can't keep contact details in Footer or in foot note section because of some formatting I need to ensure which can't maintain in footer or foot note section)
On growing of table as many rows, My content is going down, But I want to fix it at the end of my first page. if table grows bigger in size, wanted to skip the content and render table in next page.
is there any solution/work around for this?
My expected results are like below....
Page 1 Start
dynamic Table row1
dynamic Table row2
dynamic Table row3
Contact Details ,wanted to fix at the end of my first page
Page 1 end
Page 2 Start
dynamic table row 4
dynamic table row 5
........
For your scenario, ideally the contact details should be set in a footer. It is possible, but very risky.
First create a new document, either in Aspose.Words or MS Word, it will be used as a template.
Add a blank table on top
Add contact details, after the blank table
Add a bookmark, after the contact details
Now, using Aspose.Words, you can check the location of the bookmark, every time you are adding a new row in the table. If bookmark is at page 1, add new row to the first table. If bookmark is at page 2, add new row to the second table. Below is the sample code that adds rows to the table, keeping the contact details fixed on page 1.
Template document: Google drive link
Java source code is given below.
public static void main(String[] args)
{
try
{
String template = Common.DATA_DIR + "Contact Template.docx";
String saveDocument = Common.DATA_DIR + "Contact with tables.docx";
String bookmarkNameContact = "ContactEnd";
// Load the template
com.aspose.words.Document wordDoc = new com.aspose.words.Document(template);
DocumentBuilder builder = new DocumentBuilder(wordDoc);
// Find the contacts bookmark
com.aspose.words.Bookmark bookmarkContact = wordDoc.getRange().getBookmarks().get(bookmarkNameContact);
// Set the table with null
com.aspose.words.Table table = null;
// Add some rows
for (int i = 0; i < 50; i++)
{
// If contacts bookmark is on 1st page, add new rows to first table
if (getBookmarkPage(wordDoc, bookmarkContact) == 1)
{
table = (com.aspose.words.Table) wordDoc.getChild(NodeType.TABLE, 0, true);
} else
{
// If the contacts bookmark is on second page, add rows to second table
table = (com.aspose.words.Table) wordDoc.getChild(NodeType.TABLE, 1, true);
// If there is no second table, create it
if (table == null)
{
table = createNewTable(wordDoc, bookmarkContact);
}
}
// Add rows dynamically to either first or second table
addRow(wordDoc, table, "some text " + i);
}
// Save the document
wordDoc.save(saveDocument);
} catch (Exception ex)
{
System.err.println(ex.getMessage());
}

com.aspose.words.Table table = (com.aspose.words.Table) firstTable.deepClone(true);
// Add the second table after the bookmark

I work with Aspose as Developer Evangelist.
I create a jtable like this :
String name = temp.getName();
String enemy = namaFileUtama.toString();
DefaultTableModel models = (DefaultTableModel) Main_Menu.jTable4.getModel();
List<ReportMomentOfTruth> theListRMOT = new ArrayList<ReportMomentOfTruth>();
ReportMomentOfTruth rmot = new ReportMomentOfTruth();
rmot.setNameOfMainFile(name);
rmot.setNameOfComparingFile(enemy);
theListRMOT.add(rmot);
for (ReportMomentOfTruth reportMomentOfTruth : theListRMOT) {
models.addRow(new Object[]{
reportMomentOfTruth.getNamaFileUtama(),
reportMomentOfTruth.getNamaFilePembanding(),
});
}
You know, I dont get an idea. How can I get the contains the file if I click one row in jtable then the contains will be show in jTextArea ? Any suggestion ? any example perhaps ?
Thanks
edit
You know, I am using netbeans, I can get a method like this
private void jTable4MouseClicked(java.awt.event.MouseEvent evt) {
if (evt.getClickCount() == 1) {
}
}
Now how to ?
How can I get the contains the file if I click one row in jtable then the contains will be show in jTextArea?
You can better use JEditorPane that has a method setPage() that can be used to initialize the component from a URL.
Just get the values of selected row and use below code to set the content in JEditorPane.
sample code:
final JEditorPane document = new JEditorPane();
document.setPage(new File(".../a.java").toURI().toURL());
Add ListSelectionListener to detect the selection change event in the JTable
final JTable jTable = new JTable();
jTable.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
jTable.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
int row = jTable.getSelectedRow();
if(row != -1){
String firstColumnValue = jTable.getModel().getValueAt(row, 0).toString();
String secondColumnValue = jTable.getModel().getValueAt(row, 1).toString();
// load the JEditorPane
}
}
});;
