Code: Select all

pSizer_0_0->Add(new wxButton(this, wxID_OK, L"AAA"), 0, wxALIGN_RIGHT);
pSizer_0_0->Add(new wxButton(this, wxID_CANCEL, L"BBB"),1, wxALIGN_RIGHT);

Notice the "0" I added to the first button means "don't change size of this button". The "1" in the second button, together with the default "1" in the AddStretchSpacer(), means "the remaining space will be evenly distributed (because of the 1/1 relation) between this second button and the spacer".

Your code looks ok, the problem is mostly how you insert pSizer_0_0 into another sizer. E.g. if you put it into a vertical sizer, set the wxEXPAND flag so that it takes the whole width. And if you put it into a horizontal sizer, use a "proportion" value > 0 so that it can take extra space.

If you can't get it to work, please show the whole sizer related code.

void MyDlg::Init()
{
    wxBoxSizer * pSizer_0 = new wxBoxSizer(wxVERTICAL);

    // add some children to pSizer_0

    {
        wxBoxSizer * pSizer_0_0 = new wxBoxSizer(wxHORIZONTAL);

        pSizer_0_0->AddStretchSpacer();
        pSizer_0_0->Add(new wxButton(this, wxID_OK, L"OK"));
        pSizer_0_0->Add(new wxButton(this, wxID_CANCEL, L"Cancel"));

        pSizer_0->Add(pSizer_0_0);
    }

    SetSizer(pSizer_0);

    Fit();
}

pSizer_0->Add(pSizer_0_0, 0, wxEXPAND);
