    <p>Can a <code>wx.PyControl</code> contain a <code>wx.Sizer</code>?</p> <p>Note that what I am ultimately trying to do here (spinner with float values) is already answered in another question. I am particularly interested in layouting widgets within a <code>wx.PyControl</code>, a skill which might prove useful if I come across a need to make my own custom widgets. I already read through <a href="http://wiki.wxpython.org/CreatingCustomControls" rel="nofollow noreferrer">CreatingCustomControls</a>, but it didn't use sizers within the <code>wx.PyControl</code> subclass.</p> <p>Using my code below, my <code>CustomWidget</code> just doesn't look right. I'm not yet doing a <code>DoGetBestSize</code> because I think that applies to a <code>wx.Sizer</code> acting <strong>on</strong> a widget. I am actually having a <code>wx.Sizer</code> doing its thing <strong>inside</strong> a <code>CustomWidget</code>.</p> <p>Here is my code (without the event bindings between sub-widgets):<br> <strong>EDIT:</strong> Here is my corrected class code, thanks to <a href="https://stackoverflow.com/questions/3271639/wxpython-can-a-wx-pycontrol-contain-a-wx-sizer/3272377#3272377">Steven Sproat</a>:</p> <pre><code>import wx class CustomWidget(wx.PyControl): def __init__(self, parent): wx.PyControl.__init__(self, parent=parent, style=wx.NO_BORDER) # Style added. text = wx.TextCtrl(parent=self) spin = wx.SpinButton(parent=self, style=wx.SP_VERTICAL) sizer = wx.GridBagSizer() self.layout(text, spin, sizer) self.OnInit(text, sizer) def OnInit(self, text, sizer): text.SetValue(u"0.000") def layout(self, text, spin, sizer): self.SetSizer(sizer) sizer.Add(text, pos=(0, 0), flag=wx.ALIGN_CENTER) sizer.Add(spin, pos=(0, 1), flag=wx.ALIGN_CENTER) self.Fit() self.Layout() # This is what I lacked. I needed to call .Layout() self.CenterOnParent() </code></pre>

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.
