wx.grid.Grid.GetSelectedCells()

wxPython Users
1

Good day!

I want to find which cell (row, col) in my grid is selected (moving by keyboard or select by mouse).

Only one method I have found that could do something like that is wx.grid.Grid.GetSelectedCells(). But it allways returns empty list - [ ].

What am I doing wrong, or maybe there is another method?

My code is as follows. Running on windows, python 2.5, wxpython - 2.8.7.1

Thank you in advance.

import wx
import wx.grid

class TestFrame(wx.Frame):
def init(self):
wx.Frame.init(self, None, title = “Grid”, size = (640, 480))
self.grid = wx.grid.Grid(self)
self.grid.CreateGrid(50, 50)

                  #self.grid.SetSelectionMode(0)

                  self.Bind(wx.grid.EVT_GRID_SELECT_CELL, self.OnSelectCell, self.grid)

                 for row in range(10):
                               for col in range(10):
                                       self.grid.SetCellValue(row, col, "cell (%s, %s)" % (row, col))

           def OnSelectCell(self, event):

                           print self.grid.GetSelectedCells()

                           event.Skip()

app = wx.PySimpleApp()
frame = TestFrame()
frame.Show()
app.MainLoop()

                      #self.grid.SetSelectionMode(0)

                      self.Bind(wx.grid.EVT_GRID_SELECT_CELL, self.OnSelectCell, self.grid)

                     for row in range(10):
                                   for col in range(10):
                                           self.grid.SetCellValue(row, col, "cell (%s, %s)" % (row, col))

               def OnSelectCell(self, event):

                               event.Skip()

app = wx.PySimpleApp()
frame = TestFrame()
frame.Show()

I suggest you following modifications:

# Bind to other event than select cell
        self.Bind(wx.grid.EVT_GRID_CELL_RIGHT_CLICK, self.OnSelectCell, self.grid)

    def OnSelectCell(self, event):
# Select cell, range of cells, rows and column and right click on the grid
        print "Cells:\n", self.grid.GetSelectedCells()
        print "Rows:\n", self.grid.GetSelectedRows()
        print "Cols:\n", self.grid.GetSelectedCols()
        print "Top left: ", self.grid.GetSelectionBlockTopLeft()
        print "Bottom right: ", self.grid.GetSelectionBlockBottomRight()
        event.Skip()

Hi,

Event wx.grid.EVT_GRID_SELECT_CELL works fine - it is redirected to handler and all prints are performed. However, I also tried wx.grid.EVT_GRID_CELL_RIGHT_CLICK, as you suggested, results are the same:

all prints are performed, but all of functions return empty List, and my program output is as follows:
Cells:
Rows:
Cols:
Top left:
Bottom right:

I expected some row and col coordinates there.

According to the docs, GetSelectedCells() returns "an array of singly
selected cells".

If you are trying to select a range of cells, there is
wx.EVT_GRID_RANGE_SELECT.

The event has the following methods (amongst others) -

  evt.GetTopLeftCoords()
  evt.GetBottomRightCoords()
  evt.GetTopRow()
  evt.GetBottomRow()
  evt.GetLeftCol()
  evt.GetRightCol()

I have not tried any of this, but maybe it is what you are looking for.

Use GetGridCursorRow() and GetGridCursorCol().
To make things faster, in my derived wx.grid.grid I have written this function:

def CurCell(self):
    curcell = []
    curcell.append(self.GetGridCursorRow())
    curcell.append(self.GetGridCursorCol())
    return curcell

Oups...
you just have to work with the event:
event.Row, event.Col or event.GetRow(), event.GetCol()

Sorry I read to quickly.

Use GetGridCursorRow() and GetGridCursorCol().
To make things faster, in my derived wx.grid.grid I have written this function:

    def CurCell(self):
        curcell =
        curcell.append(self.GetGridCursorRow())
        curcell.append(self.GetGridCursorCol())
        return curcell

    If you are trying to select a range of cells, there is
    wx.EVT_GRID_RANGE_SELECT.

     evt.GetTopLeftCoords()
     evt.GetBottomRightCoords()
