determine the absolute position of a cell

[Fabio Spadaro]

Many people know that to determine the absolute position (relative to the screen) of a window using the method getscreenposition. Unfortunately, this method can not be used to determine the precise location of grid's cell.
I need to know the cell's location because I load a frame the time of creation of CreateCellEditor.
there is some other solution to getscreenposition?

Hi Fabio,

What you probably want to do it this:

1) Bind your grid to EVT_MOTION like this:

self.MyGrid.GetGridColLabelWindow().Bind(wx.EVT_MOTION,
self.onMouseOver)

2) In the event handler, grab the mouse position using something like
this:

pos = event.GetX()

3) Use that information to know where to put your frame.

But the mouse event is not the only possible event as you may also use
the key event ...

Well, you could bind to this instead:

self.myGrid.Bind(gridlib.EVT_GRID_EDITOR_CREATED, self.onCellEdit)

Then in the handler, get a handle on the control:

editor = event.GetControl()

and maybe this will work:

editor.GetScreenPosition()

I'm not sure though.

Something like this should do it:

r = theGrid.CellToRect(row, col)
screenPos = theGrid.GetGridWindow().ClientToScreen(r.position)

scrolled coordinates ?
