I have created a Table which is inside the form Section .Each time it expands the table size(Width) grows. I am using TableColoumnLayout for the table viewer composite.
I have checked this bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=215997 .I have no luck.
Any advice?
objectiveSection = toolkit.createSection(composite, Section.DESCRIPTION|Section.TITLE_BAR|
Section.TWISTIE|Section.EXPANDED);
objectiveSection.setActiveToggleColor(toolkit.getHyperlinkGroup().getActiveForeground());
objectiveSection.setToggleColor(toolkit.getColors().getColor(FormColors.SEPARATOR));
GridData data=new GridData(GridData.FILL, GridData.FILL, true, true);
objectiveSection.setLayoutData(data);
toolkit.createCompositeSeparator(objectiveSection);
toolkit.adapt(objectiveSection);
/**
* Creating a client inside the section
*/
Composite objective = toolkit.createComposite(objectiveSection, SWT.BORDER);
/**
* creating the object table model and object table.
*/
TableModel objectiveModel=new ObjectiveTableModel();
GridData gds = new GridData(GridData.FILL,GridData.FILL,true,true);
objectiveTable=new CustomTable(objectiveModel, objective, true, true, gds);
/**
* column for object viewer
*/
objectiveTable.createTableViewerColumn("List of Behaviors", 0);
objectiveTable.enableCellEdit();
objectiveTable.autoFocus();
toolkit.adapt(objective);
objectiveSection.setText("Behaviours");
objectiveSection.setDescription("The section contains the Behaviours of the selected operation"); //$NON-NLS-1$
objectiveSection.setClient(objective);
objectiveSection.setExpanded(true);
objectiveSection.setEnabled(true);
objectiveSection.addExpansionListener(new ExpansionAdapter() {
public void expansionStateChanged(ExpansionEvent e) {
form.reflow(false);
}
});
My table will get the values dynamically .Each time i am re sizing the column
this.table.setRedraw(false);
for (int i = 0, n = this.table.getColumnCount(); i < n; i++){
this.table.getColumn(i).pack();
int minWidth=this.table.getColumn(i).getWidth();
this.layout.setColumnData(this.table.getColumn(i), new ColumnWeightData(25,minWidth));
}
this.table.setRedraw(true );
this.composite.layout();
It seems to happen because of the following line:
GridData gds = new GridData(GridData.FILL,GridData.FILL,true,true);
You request that the table will fill its container and grab excess space.
Try instead:
GridData gds = new GridData(GridData.CENTER,GridData.CENTER,false,false);

I am trying to add a table surrounded by text to an outer table in iText 5.5.4, but the inner table disappears and I can't seem to fix the problem.
Here is what I am expecting:
*********************
* Hello World *
* +++++++++++++++++ * <--
* + Goodbye World + * <-- these 3 lines never show up in the PDF
* +++++++++++++++++ * <--
* Hello World *
*********************
Here is my code example:
public class TableTest {
public static void main(String[] args) throws FileNotFoundException, DocumentException {
final Document document = new Document(PageSize.LETTER, 21, 21, 30, 35);
PdfWriter.getInstance(document, new FileOutputStream("testTable.pdf"));
document.open();
// table 2
final PdfPTable table2 = new PdfPTable(1);
table2.setSpacingBefore(0);
table2.setHorizontalAlignment(Element.ALIGN_LEFT);
table2.getDefaultCell().setBorderColor(BaseColor.RED);
table2.getDefaultCell().setBorderWidth(1);
table2.addCell("Goodbye World");
// table 1
final PdfPTable table1 = new PdfPTable(1);
table1.setSpacingBefore(0);
table1.setHorizontalAlignment(Element.ALIGN_LEFT);
table1.setWidthPercentage(100);
table1.getDefaultCell().setBorderColor(BaseColor.BLACK);
table1.getDefaultCell().setBorderWidth(1);
// contents
Phrase phrase = new Phrase();
phrase.add(new Chunk("Hello World"));
phrase.add(table2); // <--- added but doesn't show up!
phrase.add(new Chunk("Hello World"));
table1.addCell(phrase);
document.add(table1);
document.close();
}
}
This is part of a bigger report, and I am using the tables in this scenario for border and padding.
You are using text mode (to be used when you only have text) in a situation where you should use composite mode (because you are adding a table to a cell).
Please take a look at the NestedTableProblem example:
// table 2
final PdfPTable table2 = new PdfPTable(1);
table2.setHorizontalAlignment(Element.ALIGN_LEFT);
table2.getDefaultCell().setBorderColor(BaseColor.RED);
table2.getDefaultCell().setBorderWidth(1);
table2.addCell("Goodbye World");
// table 1
final PdfPTable table1 = new PdfPTable(1);
table1.setHorizontalAlignment(Element.ALIGN_LEFT);
table1.setWidthPercentage(100);
// contents
PdfPCell cell = new PdfPCell();
cell.setBorderColor(BaseColor.BLACK);
cell.setBorderWidth(1);
cell.addElement(new Chunk("Hello World"));
cell.addElement(table2);
cell.addElement(new Chunk("Hello World"));
table1.addCell(cell);
document.add(table1);
In this code snippet, the cell object is composed of different elements (that's what composite mode is about):
In your code snippet, you add several elements to a Phrase and you add this Phrase to a PdfPCell in text mode. As one element isn't ordinary text but a table, it can not be rendered.
I'm trying to configure a dialog window like so:
#Override
protected Control createDialogArea(Composite parent) {
GridLayout dialogAreaLayout = new GridLayout();
dialogAreaLayout.numColumns = 2;
parent.setLayout(dialogAreaLayout);
GridData gridData = new GridData();
gridData.grabExcessHorizontalSpace = true;
gridData.horizontalAlignment = GridData.FILL;
gridData.minimumWidth = 300;
// the label in the first row should span across both columns
gridData.horizontalSpan = 2;
Label headlineLabel = new Label(parent, SWT.NONE);
headlineLabel.setText("example test");
headlineLabel.setLayoutData(gridData);
// the rest should be ordered in two columns
gridData.horizontalSpan = 1;
companyLabel = new Label(parent, SWT.NONE);
companyLabel("company");
companyTextfield = new Text(parent, SWT.BORDER);
companyTextfield(gridData);
...
What I'm trying to accomplish is a label in the first line, that spans across both columns and have the following fields be ordered in pairs per line. What I get with this is, that the lable (that should be left in second line) is right in first line, just as the label wouldn't span across two columns. Can anybody see, what I'm doing wrong?
Thanx again!
After setting the layoutData to headlineLabel, you are setting the horizontalSpan to 1. You need to create a new LayoutData object for every SWT widget. It is not possible to reuse them after setting them.
I have a grid that is dynamically generated based on search criteria. I render the grid in a partial view using Ajax. That all works fine.
I now need to add a checkbox column as the first column.
Also, how do I get filtering, sorting paging etc. to work now since it is in a partial view.
When i click on a header to sort I get a Page not found error and the filter Icon doesnt do anything.
And one more thing. When I try to add a GridCommandColumnSettings to the grid I get the error
"Invalid initializer member declarator"
Code is below for the gridcolumnsettings
public GridColumnSettings[] NewColumns(DataTable fullDT)
{
GridColumnSettings[] newColumns = new GridColumnSettings[fullDT.Columns.Count];
for (int i = 0; i < fullDT.Columns.Count; i++)
{
// set the visibility property for the DeliveryID
bool boolDeliveryID;
if (fullDT.Columns[i].ColumnName == "DeliveryID")
boolDeliveryID = false;
else
boolDeliveryID = true;
newColumns[i] = new GridColumnSettings
{
new GridCommandColumnSettings
{
Commands =
{
new GridEditActionCommand(),
new GridDeleteActionCommand()
},
Width = "200px",
Title = "Commands"
},
Member = fullDT.Columns[i].ColumnName,
Title = fullDT.Columns[i].ColumnName,
Visible = boolDeliveryID,
Filterable = true,
Sortable = true
};
}
return newColumns;
}
Any suggestions would be appreciated.
Thanks
I edited my post to add my partial for the Grid
Here is my partial for the grid
#(Html.Telerik().Grid<System.Data.DataRow>(Model.Data.Rows.Cast<System.Data.DataRow>())
.Name("Grid")
.Columns(columns =>
{
columns.LoadSettings(Model.Columns as IEnumerable<GridColumnSettings>);
})
.DataBinding(dataBinding => dataBinding.Ajax().Select("_DeliveryManagerCustomBinding", "Deliveries"))
.EnableCustomBinding(true)
.Resizable(resize => resize.Columns(true))
)
I don't add columns this way when I use the Telerik Grid control, but looking at what you're doing I would hazard a guess to say you will need to do something like the following:
increase the size of the newColumns array by 1 (because we're going to add in the checkbox column):
GridColumnSettings[] newColumns = new GridColumnSettings[fullDT.Columns.Count + 1];
if you want it at the beginning you will need to do the following before your for-loop:
GridColumnSettings s = new GridColumnSettings() {
ClientTemplate("<input type=\"checkbox\" name=\"checkeditems\" value=\"some value\" />")
Title("title goes in here")
};
Then you will add it into your array:
newColumns[0] = s;
and then increase the start index for your for-loop to 1:
for (int i = 1; i < fullDT.Columns.Count; i++)
the checkbox column will go at the beginning
I am using jface tableViewer.When table has no data in it ,it shows all columns correctly But when Data gets added to the table it shows extra blank space or column at the end of the table.
I am using TreeViewer + TreeViewerColumn and had this problem too, this workaround might work for your TableViewer too: Programmatically set the size of the last column on parent resize:
treeViewer.getTree().addControlListener(new ControlAdapter() {
public void controlResized(ControlEvent e) {
packAndFillLastColumn();
}
});
where the action is in
// Resize last column in tree viewer so that it fills the client area completely if extra space.
protected void packAndFillLastColumn() {
Tree tree = treeViewer.getTree();
int columnsWidth = 0;
for (int i = 0; i < tree.getColumnCount() - 1; i++) {
columnsWidth += tree.getColumn(i).getWidth();
}
TreeColumn lastColumn = tree.getColumn(tree.getColumnCount() - 1);
lastColumn.pack();
Rectangle area = tree.getClientArea();
Point preferredSize = tree.computeSize(SWT.DEFAULT, SWT.DEFAULT);
int width = area.width - 2*tree.getBorderWidth();
if (preferredSize.y > area.height + tree.getHeaderHeight()) {
// Subtract the scrollbar width from the total column width
// if a vertical scrollbar will be required
Point vBarSize = tree.getVerticalBar().getSize();
width -= vBarSize.x;
}
// last column is packed, so that is the minimum. If more space is available, add it.
if(lastColumn.getWidth() < width - columnsWidth) {
lastColumn.setWidth(width - columnsWidth);
}
}
Works well for me - you might want to set column resizable to false ;-). This can also be called when data in the last column changes (introducting / removing vertical scroll bar).
Thanks Thomas. Your idea worked for me as well, though I was using TableViewer and TableColumn.
Quoting my code so that others can take some hints.
`public void controlResized(ControlEvent e) {
if ( listOfTableColumns.size() != colProportions.length )
{
logger.warn( "Number of columns passed and size of column proportions array are different. " +
"Columns resizing shall not be effective on GUI window resizing" );
return;
}
Rectangle area = tableBaseComposite.getClientArea();
Point size = theTable.computeSize(SWT.DEFAULT, SWT.DEFAULT);
ScrollBar vBar = theTable.getVerticalBar();
int width = area.width - theTable.computeTrim(0,0,0,0).width - vBar.getSize().x;
if (size.y > area.height + theTable.getHeaderHeight()) {
// Subtract the scrollbar width from the total column width
// if a vertical scrollbar will be required
Point vBarSize = vBar.getSize();
width -= vBarSize.x;
}
Point oldSize = theTable.getSize();
if (oldSize.x > area.width) {
// table is getting smaller so make the columns
// smaller first and then resize the table to
// match the client area width
int index = 0 ;
for ( Iterator<TableColumn> iterator = listOfTableColumns.iterator(); iterator.hasNext(); )
{
TableColumn column = iterator.next();
column.setWidth( (int) numberFromPercentage( width, colProportions[index++] ) );
}
listOfTableColumns.get( listOfTableColumns.size() - 1).pack();
theTable.setSize(area.width, area.height);
} else {
// table is getting bigger so make the table
// bigger first and then make the columns wider
// to match the client area width
int index = 0;
theTable.setSize(area.width, area.height);
for ( Iterator<TableColumn> iterator = listOfTableColumns.iterator(); iterator.hasNext(); )
{
TableColumn column = iterator.next();
column.setWidth( (int) numberFromPercentage( width, colProportions[index++] ) );
}
listOfTableColumns.get( listOfTableColumns.size() - 1).pack();
}
}`
No need for complicated hacks to remove the extra unwanted column space at the end...
Just create a columnLayout:
TableColumnLayout columnLayout = new TableColumnLayout();
and then set it to each of your columns:
columnLayout.setColumnData(YOUR_VIEWER_COLUMN1.getColumn(), new ColumnPixelData(200));
columnLayout.setColumnData(YOUR_VIEWER_COLUMN2.getColumn(), new ColumnWeightData(200, 100));
Finally, set the layout on your parent composite:
parent.setLayout(columnLayout);
Full sample:
public void createPartControl(Composite parent) {
TableViewer viewer = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.FULL_SELECTION);
TableViewerColumn keyColumn = new TableViewerColumn(viewer, SWT.LEFT);
TableViewerColumn valueColumn = new TableViewerColumn(viewer, SWT.LEFT);
TableColumnLayout columnLayout = new TableColumnLayout();
columnLayout.setColumnData(keyColumn.getColumn(), new ColumnPixelData(200));
columnLayout.setColumnData(valueColumn.getColumn(), new ColumnWeightData(200, 100));
parent.setLayout(columnLayout);
}
Just guessing: maybe your columns do not get resized to fill all the table?
How do you set the widths of columns?
Consider using TableColumnLayout for the table container.
On windows, you will always get an extra column/row if the net width of all the columns that has been set up is less than the dimension of the table. So its always good to make your columns fit your table, also there is some space left for scroll bars, though I am not very sure about this, but its always better to specify whether you want vertical or horizontal scroll bars.
I used the packAndFillLastColumn() method and it worked for me. But I found one issue with it. My table was created with a border. After using the packAndFillLastColumn() method the border for the row no longer exists. I used the setLinesVisible(true) method within the packAndFillLastColumn() method but still that does not work.
So simple! Just remove this line in your table commands inside the createContents function:
table.getColumn(i).pack();
Good-luck
As a workaround use :
-For Column
use TableColumnLayout for the treeViewer's composite and set appropriate column data for each column using:
"tableColumnLayout.setColumnData(column,new ColumnWeightData(...as per your requirement));"
-For Row
Set GridData to the treeViewer's composite and provide height hint using
"gridData.heightHint = table.getItemHeight()*numberOfVisibleRows"
I found eclipse has marked it as WONTFIX.. so can not do much to remove this space..We have tp live with it...:)
To the end column we need to set the setWidth to window size or shell-size, parent-shell size like 1500,5000
final TableViewerColumn viewerColumn = new TableViewerColumn(tableViewer, SWT.NONE);
final TableColumn column = viewerColumn.getColumn();
column.setText(title);
column.setResizable(true);
column.setMoveable(true);
//set the setWidth size upto shell size or set upto to some size like 1000,1500,2000,5000
col.setWidth(comp.getShell().getSize().x); // or col.setWidth(1500) ;
return viewerColumn;
Is it possible to set the column width of CellTable in GWT?
EDIT: As of GWT 2.2 table.setWidth and table.setColumnWidth are supported
table.setWidth("100%", true);
table.setColumnWidth(nameColumn, 35.0, Unit.PCT);
table.setColumnWidth(addressColumn, 65.0, Unit.PCT);
I was able to extend the CellTable with a method that sets the widths programmatically. It's a bit of a hack since all the real methods that should do this are private to CellTable and it seems like GWT should provide this method directly, but it seems to work.
public void setColumnWidths(List<Integer> widths)
{
TableElement tel = TableElement.as(getElement());
NodeList<Element> colgroups = tel.getElementsByTagName("colgroup");
if (colgroups.getLength() == 1)
{
TableColElement cge = TableColElement.as(colgroups.getItem(0));
NodeList<Element> cols = cge.getElementsByTagName("col");
for (int j = 0; j < widths.size(); j++)
{
TableColElement column = null;
if (cols.getLength() > j)
{
column = TableColElement.as(cols.getItem(j));
}
else
{
column = cge.appendChild(Document.get().createColElement());
}
column.setWidth(widths.get(j)+"px");
}
}
}
You could use a stylename for the specific column, using the addColumnStyleName(int index, java.lang.String styleName) method.
Javadoc for CellTable
What worked for me is adding a new class in my css. This class gets applied only to select elements whose length varies depending on data.
.__gwt_cell select{
width:170px;
}
Then applying it on my particular cell style like o:
table.getColumn(3).setCellStyleNames("yourstyle");
The GWT documentation for CellTable covers this, see:
http://www.gwtproject.org/doc/latest/DevGuideUiCellTable.html
Under "Controlling Column Widths".
