    <p>I want to implement a grid with the cells that have the following behaviour:</p> <ol> <li><p>cell text should be wrapped if it doesn't fit to the cell</p></li> <li><p>newlines (\n) in the cell text should be processed as well</p></li> </ol> <p>i.e. the same behaviour as in table editors like MS Excel, OO Calc, etc. when you enable the 'wrap words' option for cells.</p> <p>I'm trying to do this as follows:</p> <pre><code>import wx import wx.grid class MyGrid(wx.grid.Grid): def __init__(self, parent = None, style = wx.WANTS_CHARS): wx.grid.Grid.__init__(self, parent, -1, style = style) self.CreateGrid(10, 10) self.editor = wx.grid.GridCellAutoWrapStringEditor() self.SetDefaultEditor(self.editor) self.SetDefaultRenderer(wx.grid.GridCellAutoWrapStringRenderer()) self.SetCellValue(0, 0, "Line1\nLine2\nLine3") self.SetRowSize(0, 100) class MyFrame(wx.Frame): def __init__(self, parent = None, title = "Multiline"): wx.Frame.__init__(self, parent, -1, title) self.Bind(wx.EVT_CHAR_HOOK, self.on_frame_char_hook) panel = wx.Panel(self) vbox = wx.BoxSizer(wx.VERTICAL) panel.SetSizer(vbox) grid = MyGrid(panel) vbox.Add(grid, 1, wx.EXPAND | wx.ALL, 5) self.grid = grid btn_exit = wx.Button(panel, -1, "Exit") vbox.Add(btn_exit, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.ALL, 10) #Proceed CTRL+ENTER as newline in the cell editor def on_frame_char_hook(self, event): if event.CmdDown() and event.GetKeyCode() == wx.WXK_RETURN: if self.grid.editor.IsCreated(): self.grid.editor.StartingKey(event) else: event.Skip else: event.Skip() if __name__ == "__main__": app = wx.PySimpleApp() f = MyFrame() f.Center() f.Show() app.MainLoop() </code></pre> <p>But this code doesn't work as expected - newlines processed correctly in the cell editor, but ignored in the cell renderer. If I remove the <code>self.SetDefaultRenderer(wx.grid.GridCellAutoWrapStringRenderer())</code> then newlines processed correcly both in the editor and renderer, but obviously auto wrapping in the renderer doesn't work.</p> <p>Does anybody know how to solve this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
