SimpleTableModel Refresh and Clear Values

[Arturo Caballero]

Hi there!

I have a little problem with SimpleTableModel.

I need to delete the values previously set to the table model. I tryied with setting a empty String[][] then invoke fireTableModelChanged but it keeps the same data.

Code:

    empty = new String[0][3];
    tdDetalle = new SimpleTableModel(empty, columns);
    tdDetalle.fireTableModelChanged();

How can I clear the rows of the TableModel?

Thanks in advance for your time.

Regards,

AC

Hi Thomas,

I understand by the docs that the metod fireTableModelChanged  of the table model will update the model and the table related will be repainted too.

Hope it helps.

Regards!

I have tried with fireTableModelChanged. without calling this method, changes arent affected, but with, it makes the changes but doesnt update the screen till I scroll.
 here my code:

tableItem = new TableItem(Display.getDisplay(this), "DeviceTable")
tableModel1 =    new SimpleTableModel(controlUnit.showDevices(),
                      new java.lang.String[]{"IP","GPS","Energy"});
         tableItem.setModel (tableModel1 );
         tableModel1.addTableModelListener(tableItem);  


// changing the values
tableModel1.setValues(controlUnit.showDevices());
           tableModel1.fireTableModelChanged();

does anyone has an idea?

thx
thomas

Have you tried refreshing the Form with some method? I think there is a hierachy, where you have to refresh first the control that encapsulates other controls.

I was looking for a refresh or repaint method either in the Form class or the Display, but couldn't find some??

Hi,

experienced the same problem with changing tablemodel dynamically. Finally opened the source code of tableItem class and found that in fireTableModelChanged method there is repaint(); string and it is commented!! Found in the web that somebody had copied the class into project folder and deleted the // in front of repaint(); You can leave everything as is and try that stupid solution:
tableItem.setColorSchema(tableItem.getColorSchema);
cause in this method of TableItem class repaint() left uncommented by the author.
that worked with me.
PS. neither of recommended in the web works but only this variant.
