wx.grid - opening editor with one click

wxPython Users
1

Hi all,

I'm creating a wxPython app that uses wx.Grid and I need to place custom editors (wx.ComboCtrl) in one row of that grid.

The problem I'm facing now is that user needs to click once on a cell to set focus on it (outline is drawn around clicked cell) and then click again to open editor (a combo box).

My event handler, bound to EVT_GRID_CELL_LEFT_CLICK, calls grid.ShowCellEditControl() (and prints something on console, so I know that event is received), but ShowCellEditControl() seems to fail for the first click, but works after second click.

I've found its source in generic\grid.cpp and the only place it seems to be able to quit without showing anything is "if ( !IsVisible( m_currentCellCoords, false ) )".

Now my question is - how can I set 'm_currentCellCoords' from Python level? It seems like setting it to currently clicked cell and *then* calling ShowCellEditControl() will do the trick.

Any suggestions?

Kind regards,

Adam Bielanski.

Take a look at the wx.lib.mixins.grid.GridAutoEditMixin class.

Man, you're simply awesome....

I took this task from my friend here, who struggled with it for several hours. I also spent some time on it, totally unaware of such mixin.

Tested it a moment ago it looks like it works, right out of the box.

Tomorrow I'll take a closer look to see how it works :slight_smile:

Thank you very much!

I’ve found much easier sollution somewhere on Cpp-WX forums:

grid.Bind(wx.grid.EVT_GRID_CELL_LEFT_CLICK, OnGridClicked)

def OnGridClicked(e):
e.GetEventObject().SetGridCursor(e.GetRow(), e.GetCol())
e.Skip()
