Hello Jide's,

I've played a little bit with the JTable's Header components, cause I don't like that "..." if the column gets smaller.

I want to have the text wrapped into more than one lines, if one line doesn't fit the table columns width. I've tried many things (LinebreakMeasurer, creating new Renderer, overwriting JTableHeader)... Some works, but there is a real big bug in Sun's JTable implementation:

Maybe you have specified your own Renderer in JTableHeader.
Then you have put this JTable into a Scrollpane (with JTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF))
Now you drag a columnwidth so that the sum width of all columns is greater than the scrollpane.
If you now scroll to the right, the Header is not exactly repainted....

So this all fails...

Do you have another possibility or can you make a solution to show multiline headers???

Would be great!

Greetings,
Robert

I am aware of the bug you mentioned. We have a multi-line implementation. It is actually used before in SortableTable. Recently we truned it off because we want to keep the XP style table header. Our implementation doesn't keep XP style. There is another customer asking for this too. So in next release we will move it to JideTable level and off by default. Just one method call can turn in on. However it doesn't wrap automatically. You have to put \n in the column name to split lines. Is it good enough for you?

Thanks,

Well... it is good to have this method to switch it on.

Maybe you can introduce a enum for this:

HEADER_WRAP_OFF
HEADER_WRAP_NEWLINE
HEADER_WRAP_AUTOMATICALLY

Our customer is asking for this feature, cause our table can have many columns and he want to resize the columns and like to have an automatical wrap (like that if you add this "<html>" before the label's text property)...

So with the enum one could customize the behavior of the header wrapping to either off, wrapping at the \n or wrapping automatically...

What do you think?

Has this or some other method for a multiline header been implemented? I tried setting the header renderer to a MultilineTableCellRenderer, and the text does wrap, but it doesn't look very good; the cells are plain formatted like table cells, and the header row is sized much taller than it needs to be.

by **JIDE Support** » Fri Jul 13, 2007 7:43 am

MultilineTableCellRenderer is for table cells, not for table header. As you can read from the posts above, we currently don't have a nice way to wrap header. The only way right way is to use SortTableHeaderRenderer. You can see how to enable it at the javadoc of setSortTableHeaderRenderer of JideTable.

Thanks,

by **therodet** » Fri Jul 13, 2007 8:12 am

Not the prettiest solution, but it does do what I wanted. Thank you for the prompt reply.

by **JIDE Support** » Fri Jul 13, 2007 8:16 am

I certainly agree. That's why I said we don't have a nice way.

Thanks,

We achieved the multiline feature by having our header renderer extends JTextArea. The only problem is that the look is not XPStyle, but we need it to "multline" on its own as in a multi lingual scenario we wouldnt know where exactly to put the "\n" in the properties file.
This feature should ideally be provided by Sun itself.

HI,
I am new to JIDE and I am also having problem enabling the multi-line header. I tried the setSortTableHeaderRenderer as as shown in the code below. This code works fine but not until I enable the Filter. What I figured out from reading the doc is that the AutoFilterTableHeader creates a new FilterableTableModel and then resets the actual table model with the new FilterableTableModel. How do I tell AutoFilterTableHeader that I want multi-line header. Basically, it should treat a "\n" in the column name as new line.

Code: Select all: protected void initTable() { super.initTable(); setSortTableHeaderRenderer(); } protected JTableHeader createDefaultTableHeader() { return new JTableHeader(columnModel); } }

Thanks.

Unfortunately it is not possible with both multiple line and auto-filter features.

Thanks,

by **mgs** » Mon Dec 01, 2008 1:34 pm

That is unfortunate. Our product heavily uses multi-line header and being able to suport is essential. Is there a way to set the Header Renderer in Auto-Filter?

by **JIDE Support** » Mon Dec 01, 2008 1:48 pm

It will require quite an effort to get it working. Let me know if you are willing to sponsor such an effort through a custom contract.

Thanks,

Hi,

Will this feature work with sortable table if override initTable() and call setSortTableHeaderRenderer()?
I tried this with SortableTable. It is not working.

Let me know if we can have multi line sortable table.

by **infn** » Thu Jun 04, 2009 9:09 pm

Is anybody there..???

by **JIDE Support** » Thu Jun 04, 2009 9:16 pm

Sorry for the late reply. I don't think it will work as AutoFilterTableHeader doesn't take the renderer you set. I wonder if you can use html code to do the multilione text as we are using JLabel inside AutoFilterBox.

by **infn** » Thu Jun 04, 2009 9:41 pm

I tried using HTML text. But there are some problems in setting columns heights for the headers.
Also the text is not rendered properly. When I click on the column header the text moves on top and on mouse release it comes back to normal position.

by **JIDE Support** » Fri Jun 05, 2009 3:04 pm

Please try the following code to set the height for the table header. I tried it in our SortableTableDemo.

Code: Select all: _sortableTable.getTableHeader().setPreferredSize(new Dimension(_sortableTable.getTableHeader().getPreferredSize().width, 40));

You probably also need override the cell editor of the table header just like you did to the renderer. Once you click the header, it will enter edit mode automatically.

Thanks,

by **infn** » Mon Jun 08, 2009 5:04 am

Hi,

As per my earlier reply to set HTML text to table header I haven;t overridden any renderer. Please let me know the renderer and editor class that I have to set to get it working with sortable table. The table header get distorted in I move my scrollbars and move my mouse over the header.

Thanks & Regards

I could not notice the renderer issue while mouse over the header. Below is my test case FYI.

Hi infn,
I am also using MultiLine table header. I tried several options and what I found working is using Cell renderer that format the Header. However, when you enable the Filter it will not use the renderer that you set so you will have to override the customizeAutoFilterBox to format the header.

Below is the sample code. It will not compile right away as I just cut and pasted it from my code. Just remove irrelevant stuff. I hope this gives you some idea.

AutoFilterTableHeader

Code: Select all: import javax.swing.Icon; import javax.swing.JTable; import javax.swing.table.TableModel; import java.util.Comparator; import com.jidesoft.grid.AutoFilterBox; import com.jidesoft.grid.AutoFilterTableHeader; import com.jidesoft.grid.FilterableTableModel; import com.jidesoft.grid.FilterableTableModelEvent; import com.jidesoft.grid.FilterableTreeTableModel; import com.jidesoft.grid.IFilterableTableModel; import com.jidesoft.grid.SortableTable; import com.jidesoft.grid.TreeTable; public class CNAutoFilterTableHeader extends AutoFilterTableHeader { private JTable _table = null; private CNTablePanel _nTable = null; public CNAutoFilterTableHeader(CNTablePanel nTable) { super(nTable.getTable()); _table = nTable.getTable(); _nTable = nTable; } @Override protected IFilterableTableModel createFilterableTableModel(TableModel model) { if (_table instanceof TreeTable) { return new FilterableTableModel(model) { @Override public boolean isColumnAutoFilterable(int column) { return true; } @Override public Object[] getPossibleValues(int column, Comparator comparator) { return super.getPossibleValues(column, new Comparator(){ public int compare(Object firstObj, Object secondObj) { try { if (firstObj instanceof Comparable && secondObj instanceof Comparable) { return ((Comparable)firstObj).compareTo(secondObj); } else { String str1 = firstObj.toString(); String str2 = secondObj.toString(); return (str1.compareToIgnoreCase(str2)); } } catch (Exception e) { e.printStackTrace(); return -1; } } }); } @Override protected boolean shouldPossibleValueBeIncluded(Object value,int columnIndex) { if (value == null) return false; return !(value.toString().equals("")); } }; } else { return new FilterableTreeTableModel(model) { @Override public boolean isColumnAutoFilterable(int column) { return true; } @Override public Object[] getPossibleValues(int column, Comparator comparator) { return super.getPossibleValues(column, new Comparator(){ public int compare(Object firstObj, Object secondObj) { try { if (firstObj instanceof Comparable && secondObj instanceof Comparable) { return ((Comparable)firstObj).compareTo(secondObj); } else { String str1 = firstObj.toString(); String str2 = secondObj.toString(); return (str1.compareToIgnoreCase(str2)); } } catch (Exception e) { e.printStackTrace(); return -1; } } }); } @Override protected boolean shouldPossibleValueBeIncluded(Object value,int columnIndex) { if (value == null) return false; if (value instanceof JobStatus ) { String str = ((JobStatus)value).toString(); if (str.equals(StringBank.UNKNOWN)) return false; else return!(str.equals("")); } return !(value.toString().equals("")); } }; } } @Override public void filterableTableModelChanged(FilterableTableModelEvent event) { super.filterableTableModelChanged(event); _nTable.setPreferredWidthOfColumns(); } protected void customizeAutoFilterBox(AutoFilterBox autoFilterBox) { autoFilterBox.setBackground(Utilities.COLOR_LIGHT_LIGHT_GREY); if (autoFilterBox.getFilterTitleFormatter() ==null) { autoFilterBox.setFilterTitleFormatter(new Formatter()); } super.customizeAutoFilterBox(autoFilterBox); autoFilterBox.setShowFilterName(true); } protected Icon createSortIcon(SortableTable table, boolean ascending) { if (ascending) return RuntimeContext.upIcon; else return RuntimeContext.downIcon; } class Formatter implements AutoFilterBox.FilterTitleFormatter { String filter = ""; public String formatColumnTitle(String columnName, com.jidesoft.filter.Filter[] filters) { filter = ""; if (filters !=null && filters.length > 0) { if ( filters[0].getName().equals("All") == false) filter = ":" + filters[0].getName(); } // System.out.println("formatColumnTitle:: " + columnName + ", filter: " + filter); return "<html><body>" + columnName + filter + "</body></html>"; } public String getFilterName() { return filter; } public void clearFilter() { filter=""; } } }

RENDERER

Code: Select all: public static class CNTableHeaderRenderer extends DefaultTableCellRenderer { GradientPanel panel = null; int maxHeight = 0; int pady = 10; public CNTableHeaderRenderer(boolean darkHeader) { if (darkHeader) panel = new GradientPanel(new GridBagLayout(), Utilities.COLOR_GRADIENT1_DARKER, Utilities.COLOR_GRADIENT2, GradientPanel.VERTICAL); else panel = new GradientPanel(new GridBagLayout(), Utilities.COLOR_GRADIENT2, GradientPanel.VERTICAL); } public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { Component actualRenderer = super.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column); if (table != null) { JTableHeader header = table.getTableHeader(); if (header != null) { actualRenderer.setForeground(header.getForeground()); actualRenderer.setBackground(header.getBackground()); actualRenderer.setFont(header.getFont().deriveFont(Font.BOLD)); } } Component headerComponent = null; String stringValue = (value == null) ? "" : value.toString(); GridBagConstraints constraints = new GridBagConstraints(); if (stringValue.indexOf('\n') != -1) { JPanel cellPanel =new JPanel(new GridBagLayout()); cellPanel.setOpaque(false); constraints = new GridBagConstraints(); String totalString = stringValue; JLabel tempLabel = null; int rows =0; while(totalString.indexOf('\n') != -1) { String partString = totalString.substring(0, totalString.indexOf('\n')); tempLabel = new JLabel(partString); tempLabel.setHorizontalAlignment(JLabel.CENTER); tempLabel.setOpaque(false); tempLabel.setFont(actualRenderer.getFont()); cellPanel.add(tempLabel, Utilities.getConstraints(constraints, GridBagConstraints.RELATIVE, GridBagConstraints.RELATIVE, GridBagConstraints.REMAINDER, 1, 1, 0, GridBagConstraints.NORTH, GridBagConstraints.HORIZONTAL)); totalString = totalString.substring(totalString.indexOf('\n')+1); rows++; } tempLabel = new JLabel(totalString ); tempLabel.setHorizontalAlignment(JLabel.CENTER); tempLabel.setFont(actualRenderer.getFont()); cellPanel.add(tempLabel, Utilities.getConstraints(constraints, GridBagConstraints.RELATIVE, GridBagConstraints.RELATIVE, GridBagConstraints.REMAINDER, GridBagConstraints.REMAINDER, 1, 1, GridBagConstraints.NORTH, GridBagConstraints.HORIZONTAL, new Insets(0,0,3,0))); headerComponent = cellPanel; panel.removeAll(); panel.add(headerComponent, Utilities.getConstraints(constraints, GridBagConstraints.RELATIVE, GridBagConstraints.RELATIVE, GridBagConstraints.RELATIVE, GridBagConstraints.REMAINDER, 1, 1, GridBagConstraints.NORTH, GridBagConstraints.BOTH, new Insets(3,3,3,3))); int h = (tempLabel.getFontMetrics(tempLabel.getFont()).getHeight() + 10) * rows; //headerComponent.getPreferredSize().height ; if (h > maxHeight) { maxHeight = h; } } else { JLabel label = (JLabel) actualRenderer; label.setText((value == null) ? "" : value.toString() ); label.setHorizontalAlignment(JLabel.CENTER); label.setVerticalAlignment(JLabel.NORTH); label.setOpaque(false); headerComponent = label; panel.removeAll(); panel.add(headerComponent, Utilities.getConstraints(constraints, GridBagConstraints.RELATIVE, GridBagConstraints.RELATIVE, GridBagConstraints.RELATIVE, GridBagConstraints.REMAINDER, 1, 1, GridBagConstraints.NORTH, GridBagConstraints.NONE, new Insets(3,3,3,3))); int h = headerComponent.getPreferredSize().height ; if (h > maxHeight) { maxHeight = h; } } panel.setPreferredSize(new Dimension((int)headerComponent.getPreferredSize().getWidth() + 30,maxHeight + pady)); return panel; } }

by **JIDE Support** » Mon Jun 08, 2009 11:48 am

Please try override AutoFilterTableHeader#createDefaultEditor() to customize the editor class, just like you did at the renderer class.

The default implementation of AutoFilterTableHeader#createDefaultEditor() is listed below, FYI.

Code: Select all: protected TableCellEditor createDefaultEditor() { if (isAutoFilterEnabled()) { return new AutoFilterTableHeaderEditor() { @Override protected void customizeAutoFilterBox(AutoFilterBox autoFilterBox) { autoFilterBox.applyComponentOrientation(AutoFilterTableHeader.this.getComponentOrientation()); super.customizeAutoFilterBox(autoFilterBox); AutoFilterTableHeader.this.customizeAutoFilterBox(autoFilterBox); } }; } else { return null; } }

Thanks,

Here is a solution to get multiline headers working with SortableTable. You can use HTML in your header names to specify how you want it to wrap eg. <html>Multiline Header</html>.

Code: Select all: myTable = new SortableTable(myModel) { protected JTableHeader createDefaultTableHeader() { return new MultilineTableHeader(columnModel); } }; /** * BUG: Default JTable header renderer does not properly calculate * preferred height when any of the columns has a multiline column name. * This is a fix proposed on the sun website. * http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4292511 */ private static class MultilineTableHeader extends SortableTableHeader { private int preferrredHeight = -1; public MultilineTableHeader(TableColumnModel cm) { super(cm); } private Component getHeaderRenderer(int columnIndex) { TableColumn aColumn = getColumnModel().getColumn(columnIndex); TableCellRenderer renderer = aColumn.getHeaderRenderer(); if (renderer == null) { renderer = getDefaultRenderer(); } return renderer.getTableCellRendererComponent(getTable(), aColumn.getHeaderValue(), false, false, -1, columnIndex); } private int getPreferredHeight() { if (preferrredHeight == -1) { preferrredHeight = 0; TableColumnModel columnModel = getColumnModel(); for (int column = 0; column < columnModel.getColumnCount(); column++) { Component comp = getHeaderRenderer(column); int rendererHeight = comp.getPreferredSize().height; preferrredHeight = Math.max(preferrredHeight, rendererHeight); } } return preferrredHeight; } @Override public Dimension getPreferredSize() { return new Dimension(super.getPreferredSize().width, getPreferredHeight()); } @Override public void columnAdded(TableColumnModelEvent e) { preferrredHeight = -1; super.columnAdded(e); } @Override public void columnRemoved(TableColumnModelEvent e) { preferrredHeight = -1; super.columnRemoved(e); } }

Thanks for sharing. We will try to include your code in default SortableTableHeader in 2.9.0.

Thanks,

Just so you know, your code is included in 2.9.0 just released.

HI,
My table model returns JLabel for some of the columns (which is used to create SortableTableModel) asa result the AutoFilterbox List which contains all possible values displays
JLabel.toString instaed of the column value in filter List.
I am trying to customize AutoFilterTableHeaderRenderer in following way

TableColumn tableColumn = portColumnModel.getColumn(column);
if(column==7 || column==8 || column==9 ){
tableColumn.setCellRenderer(CustomColumnRenderer.getInstance());
AutoFilterTableHeaderRenderer headerRenderer=new AutoFilterTableHeaderRenderer();
headerRenderer.setListCellRenderer(new CustomListCellRenderer());

tableColumn.setHeaderRenderer(headerRenderer());

private static class CustomListCellRenderer extends DefaultListCellRenderer {

public Component getListCellRendererComponent(JList list, Object value,int index,boolean isSelected, boolean cellHasFocus)

{

super.getListCellRendererComponent(list, value,
index, isSelected, cellHasFocus);
setText((String) value);

return this;

}
}

but the filter Drop down for these columns still displays JLabel.toSTring instead of column values.
Control never goes inside getListCellRendererComponent.

Custom cell renderer works fine and I see values in table column but header still shows JLabel.toString for this columns

Appreciate your help
