I have the same problem of Harvey, in a similar GUI setup as the one below:

+--------------------------------------+
| wxPanel (wxBoxSizer Horizontal)      |
|  +--------------+---------------+    |
|  |wxStaticText 1|wxTextCtrl    0|    |
|  +--------------+---------------+    |
+--------------------------------------+

The wxPanel's content is managed by a wxBoxSizer, and it could only grow  =

horizontally but not vertically, and it is not a TLW, but it is child of  =

some other panel. I would like to set the wxStaticText with a proportion  =

of 1, so that it could change its size accordingly when the wxPanel is  =

getting resized, and the wxTextCtrl with a proportion of 0, so that it has  =

a fixed size. Basically the wxStaticText contains long text which could  =

also be hidden when the wxPanel is getting a smaller horizontal width, but  =

the wxTextCtrl must always be visible.

The problem is that if I add to the right others wxStaticTexts (or other  =

controls) and wxTextCtrls, then when the wxPanel gets smaller, the  =

wxTextCtrls will simply go over the wxStaticTexts (or said in another way,  =

the controls with no proportion will go over the ones with a proportion of  =

1). I tryed to set a minimal size on the panel (using  =

wxPanel::SetMinSize() or wxPanel::SetSizerAndFit()) without luck. Also  =

tried setting SetItemMinSize for all the controls with proportion of 1,  =

but it did not removed the problem. I also tryed to add some tags to the  =

XRC like setting <minsize>50,-1</minsize> on the <object  =

class=3D"sizeritem"> for the objects with a 0 proportion, but still nothing=
  =

to do.

Any hint?

Greetings,
Luca

p.s.
The XRC looks like:

   <object class=3D"wxPanel" name=3D"ID" subclass=3D"Control">
         <style>wxWANTS_CHARS|wxFULL_REPAINT_ON_RESIZE|wxTAB_TRAVERSAL</sty=
le>
         <object class=3D"wxBoxSizer">
             <orient>wxHORIZONTAL</orient>
             <object class=3D"sizeritem">
                 <flag>wxALIGN_CENTER_VERTICAL|wxLEFT|wxFIXED_MINSIZE</flag>
                 <border>1</border>
                 <option>1</option>
                 <object class=3D"wxStaticText" name=3D"ID_YSCALEST">
                     <style>wxALIGN_RIGHT</style>
                     <label>Y Scale (m/s=B2/div)</label>
                 </object>
             </object>
             <object class=3D"sizeritem">
                 <flag>wxGROW|wxLEFT|wxTOP|wxBOTTOM|wxFIXED_MINSIZE</flag>
                 <border>0</border>
                 <object class=3D"wxTextCtrl" name=3D"ID_YSCALETC">
                     <size>60,-1</size>
                     <style>wxTE_PROCESS_ENTER|wxRAISED_BORDER|wxWANTS_CHAR=
S</style>
                 </object>
             </object>
