Hey everybody,

I can't get this to work! It seems like it doesn't matter whether row > 12 or < 12.
The Click() or DblClick() event is only fired for rows that have been within a visible range!
As soon as rows are affected by the vertical scroll pane there is no Click() event.

Try the above sample and set JBGrid1.Height = 90 !
On rows > 6 I don't get events!

I actually need the DblClick() event to be fired else I could just use the MouseUp() event but how could I catch the DblClick() over the JBGrid there or else?

Or maybe there is some way to go through JBGrid1.Parent.... that I haven't found yet?


Does anybody know how to work around this?

Is there any other post about this?

That's weird!

The MouseDown event gets triggered as expected:

The DoubleClick might be devoted to cell editing.

Click and dblClick on JBGrid and its header

Hey there A1880,

I kind of figured you would be there... ;)

Well I got a solution for now!

   ' capture a single click on the table header for sorting!

  	Debug.Print "header clicked " & JBGrid1.Header(JBGrid1.Parent.getColumnModel.getColumnIndexAtX(arg2.getX))

   ' capture dblclick on rows you have to scroll to!!

End Sub

Public Sub mouseReleased(arg2 As MouseEvent)
End Sub

Public Sub mouseEntered(arg2 As MouseEvent)
End Sub

Public Sub mouseExited(arg2 As MouseEvent)
End Sub


It might not be very elegant but it works for me. I need the grid to be set to JBGrid1.Editable = jbNotEditable
Anything else does not work well with this solution !!
Also the MouseDown() event gets fired twice on the dblClick. But that could be worked around easyly.

happy that the .Parent (s) are there

I just realized that depending on from where the mouse is moving towards the grid header you get different values for arg2.getY ! Aproaching from S you get values <= JBGrid1.HeaderHeight over the first row.

You can also use:

Public Sub mouseClicked(arg2 As MouseEvent)
   ' capture a single click on the table header for sorting!
'   If arg2.getY < JBGrid1.HeaderHeight  Then 
   If InStr(arg2.getComponent,"JTableHeader")  Then 
  	Debug.Print "header clicked " & JBGrid1.Header(JBGrid1.Parent.getColumnModel.getColumnIndexAtX(arg2.getX))
   End If
   ' capture dblclick on rows you have to scroll to!!
   If arg2.getClickCount = 2 Then Debug.Print "dblclicked " & JBGrid1.Parent.getSelectedRow & ";" & JBGrid1.Parent.getSelectedColumn
End Sub

I really don't like it very much since "JTableHeader" might change in a different versions or else!

to be continued I guess ....
