Tooltip for jtable column?

Hi, all
I wrote some code tried to show tooltip on jtable's specific column, but it won't work. The code looks like this:
Vector tooltip=new Vector();
int i;
for(i=0;i<10;i++) {
tooltip.add("<some tooltip string");
for(i=0;i<tooltip.size();i++) {             
System.out.println((String)tooltip.get(i));
((DefaultTableCellRenderer)demoTable.getCellRenderer(i,1)).setToolTipText((String)tooltip.get(i));
In the later loop, System.out.println show exactly tooltip text. But when the table show up, all tooltip text show the same text, the last string stored in Vector tooltip. What's wrong with the above code?
Thanks,

er - I think this is cos that only one renderer is used, and it's reused for each component.
if you subclass the DefaultTableCellRenderer, and in the getTableCellRendererComponent() and then set the tooltiptext in there in that method.
otherwise you will get the incorrect info.
(I think that's right anyway)

  • Is there a way to have tooltips for every column in a TableView?

    Hi there!
    I found in documentation that any node and control can show a tooltip ( http://docs.oracle.com/javafx/2/api/javafx/scene/control/Tooltip.html ) but I can't get tooltips to work for TableColumn (a column from TableView).
    Do you have any idea how could I have tooltips for each column of the table view?

    TableColumn's are neither controls nor nodes, so you can neither set nor install tooltips on them.
    You can use cellfactories to set tooltips on cells generated from the factories.
    You can use css style lookups (node.lookup function) to get access to table nodes (such as the headers) after the tableview has been displayed on a stage and then manipulate the displayed nodes to add tooltips. It's not a great approach, but it is the only approach I know at the moment that would work.

  • Adding different tooltip for a column in table??

    Hi here,
    I have read the similar title "Adding ToolTip for individual cell in the table".
    The method that use "tableModel" and "override getToolTipText" for individual cell is useful for individual cell with tooltip that i have tried.
    How could i get the tooltip for each columns and show every row value on each tooltip.I wish when mouse moved above a column and the column could show all of that column's row value.
    Please help me.
    Thanks..

    your explanation sounds a bit confusing but if i got you right
    you could do something like this in your table
    public String getToolTipText(MouseEvent me)
          int row = this.rowAtPoint(me.getPoint());
          StringBuffer tooltip = new StringBuffer();
          for(int i=0; i<getColumnCount; i++)
             tooltip.append(getValueAt(row, i).toString());
          return tooltip.toString();
       }

  • Deactivate Tooltips for every column in ALV

    Hi Everybody,
    how can i deactivate the tooltip for every column in a ALV.
    regards,
    Sid

    The logic to set the tooltip goes something like this:
    data l_table type ref to cl_salv_wd_config_table.
      l_table = l_salv_wd_table->get_model( ).
      data l_column type ref to cl_salv_wd_column.
    data l_header type ref to cl_salv_wd_column_header.
      l_column = l_table->if_salv_wd_column_settings~get_column( 'CREATED_BY' ).
      l_header = l_column->get_header( ).
      l_header->set_prop_ddic_binding_field(
        property =  if_salv_wd_c_ddic_binding=>bind_prop_tooltip
        value = if_salv_wd_c_ddic_binding=>ddic_bind_none ).
      l_header->set_tooltip( ` ` ).
    However this logic just sets it for one column at a time.  If you want to do all of them then you would need to loop through a listing of the columns and repeat this logic for each one. Instead of using if_salv_wd_column_settingsget_column, you could use the method if_salv_wd_column_settingsget_columns to return an internal table of object instances for each column object defined in the ALV.

  • Maximum Allowed Text Length for JTable Column

    Can you please help me with a JTable Doubt

  • Tooltips for report column headings

    Hello,
    I have a normal report, and I wanted to have either a tooltip or a cluetip for the report column headings. Can anyone please help me with this issue.
    thanks,
    orton

    Hi!
    One way would be to adjust the report template. But this is quite difficult if you haven't done this before.
    Maybe this forum post helps: Re: oracle apex and extjs grid table
    Hmm on the other side why don't you just add some html tags inside the report column headers? I would suggest this example: http://apex.oracle.com/pls/otn/f?p=25110:5
    &lt;span TITLE="header=[Help] body=[Helptext]";>YOUR COLUMN HEADER&lt;/span>Best regards,

  • Cell tooltip for ALV

    Hello experts,
    I am new to ALV development. I have created an ALV grid report which displays data fetching from DDIC tables.
    I want to display tooltip for each individual cell of the ALV, I know about using field category property SELTEXT_M but its used for entire column tooltip. My requirement is to display tooltip for individual cell in the grid.
    Please provide me simple explanation to use tooltip for cell in ALV.
    Simple example code would be appreciated.
    Thanks in advance.
    Regards,
    Viral Patel

    Hi,
    If you are using OOPS ALV then, there is a field available in the field catalogue : TOOLTIP which you can use to display the tooltip for the column header.
    try this:
    wa_fcat-TOOLTIP = '-tooltip--'.
    I hope it helps you.
    Thanks & Regards,

  • Dynamic tooltips on alv column

    I am displaying one alv column as the traffic lights icon.
    Depending on whether it is red, yellow or green, i want to have a different tooltip for this column.
    is this possible? if yes then can someone please tell me how to do it?
    regards,
    Priyank

    Well Sascha,
    Thanks for the response but i have a slight change in requirement now. The tooltip content will have to be fetched from the backend (database level) now through the function module which is returning the data to be displayed in the ALV. Thus, the option that seems available now is to get the tooltip content in another column in the alv, keep this column hidden and use the content of this column as the tooltip for the traffic lights column.
    Any direct way of doing this?
    By the way i tried using the following code in the domodifyview method to see if it works....did not work for me....let me know what wrong i might have been doing.
      DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage,
            l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table,

      IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
        l_ref_cmp_usage->create_component( ).

  • How to make tooltip for DataGridColumn

    Hi, I'm trying to get a tooltip for whenever the user mouses
    over a column header in a DataGrid. I've seen some talk about
    creating my own ItemRenderer to do this but looking at the Flex
    docs, I see that the existing DataGridItemRenderer for a
    DataGridColumn has a tooltip attribute but I have been unsuccessful
    in getting it to work. Should I in fact make my own ItemRenderer or
    is there any way to expose it in the existing DataGridItemRenderer?
    Can anyone advise what the best way to do this is? Thanks!

    We can do like this:
    l_DataGridColumn.headerRenderer=new ClassFactory(YourHeaderItemRenderer);// use custom renderer instead of the default DataGridItemRenderer
    And in you class YourHeaderItemRenderer extends DataGridItemRenderer, you can override some method:
    override public function set toolTip(value:String):void {
         //set toolTip value here:    
         toolTip= "column description";
    this one is not dynamic, so if we want to,  we can extend the DataGridColumn to add the toolTip field, and use it:
    l_DataGridColumn.headerRenderer=new ClassFactory(YourHeaderItemRenderer);// use custom renderer instead of the default DataGridItemRenderer
    l_DataGridColumn.toolTip="compute it here";
    override public function set toolTip(value:String):void {
         //set toolTip value here:    
         toolTip= (data as YourDataGridColumn).toolTip;
    Of course in this case, the dataGrid columns must use the YourDataGridColumn instead of DataGridColumn.
    All that to have a toolTip for the column, it's sad :-)

  • Setting tooltip for columns in a JTable

    Hi!
    I have a JTable inside a JScrollPane. How do I set tooltip for each columnheader of the JTable?
    I have noted that if I don�t have the JTable within the JScrollPane, the columnheaders are not shown.
    Regards
    Johan

    1) You need to set the tooptip text on the renderer for the column (yourTable.getColumnModel().getColumn(...).getHeaderRenderer()).
    2) The header is a separate component to the table. When you add a table to a scroll pane it automatically adds the header to the scroll pane too. You can get the component (yourTable.getTableHeader()) and add it to your own container if you wish.

  • Different number of rows for different columns in JTable

    hi
    I need to create a JTable with different number of rows for different columns...
    Also the rowheight should be different in each column...
    say there is a JTable with 2 columns... Col1 having 5 rows and column 2 having 2 rows...
    The rowHeight in Col2 should be an integer multiple of Rowheight in Col1
    how do I do this ??
    can anybody send me some sample code ?????
    thanx in advance

    How about nesting JTables with 1 row and many columns in a JTable with 1 column and many rows.
    Or you could leave the extra columns null/blank.
    You could use a GridBagLayout and put a panel in each group of cells and not use JTable at all.
    It would help if you were more specific about how you wanted it to appear and behave.
