Expand an wxChoice object from xrc file

wxPython Users

Hi,
I have this piece of xrc file, used to build the gui:

wxHORIZONTAL 
      <object class="sizeritem">
        <object class="wxBoxSizer">

          <orient>wxVERTICAL</orient>

          <object class="sizeritem">
            <object class="wxStaticText">
            <label>Item:</label>
          </object>
          <flag>wxRIGHT|wxALIGN_CENTRE_VERTICAL</flag>
          <ratio>0</ratio>
        </object>

        <object class="sizeritem">
          <object class="wxChoice" name="SelectItem">
            <label>Select item</label>
          </object>
          <flag>wxALL|wxEXPAND|wxALIGN_CENTRE</flag>
          <ratio>0</ratio>
        </object>

``

The problem is that the` wxChoice object doesn’t expand.
Any idea?

Thank you very much.```

Are you editing this file by hand? Because the nesting here does not seem to be correct. You have:

horizontal box sizer

sizer item #1

box sizer (unknown orientation)

sizer item #2

vertical box sizer

sizer item #3

static text

sizer item #4

wxChoice

The problem here (which is difficult to see with the spacing) is that the wxChoice sizer item #4 is nested inside sizer item #2. The sizer items should all be peers of each other, and each sizer item should contain exactly one control. I can’t tell what layout you’re really looking for here; is the wxChoice supposed to be inside of the vertical box sizer, or in the outer one? And why do you have the extra sizer inside the horizontal box?
