Can column of wxGridBagSizer expand? Topic is solved

[Ronald]

In the sample code below, when the window resizes, can the 2nd column of wxGridBagSizer fit horizontally?

Code: Select all

wxBoxSizer * sizer_1 = new wxBoxSizer(wxVERTICAL);
{
    wxGridBagSizer * sizer_2 = new wxGridBagSizer(10, 10);
    {
        int row = 0;

        wxSize path_text_ctrl_size(500, 25);

        {
            sizer_2->Add(new wxStaticText(this, wxID_ANY, L"Input file paths"),
                            wxGBPosition(row, 0),
                            wxDefaultSpan,
                            wxALIGN_TOP);
            _lv_input_file_paths = new FilePathListView(this);
            sizer_2->Add(_lv_input_file_paths,
                            wxGBPosition(row, 1),
                            wxDefaultSpan,
                            wxALIGN_CENTER_VERTICAL | wxEXPAND);
            sizer_2->Add(new wxButton(this, ID_BTN_SELECT_INPUT_FILES, L"...", wxDefaultPosition, wxSize(30, 25)),
                            wxGBPosition(row, 2),
                            wxDefaultSpan,
                            wxALIGN_TOP);
        }
        {

wxGridBagSizer derives from wxFlexGridSizer, so you can use wxFlexGridSizer::AddGrowableCol

Nice, it works, thanks.
BTW, it actually sets an existing column growable instead of adding a new growable column, right?

Yes. The naming is a little ambiguous.
