wx-3.3.0 - Ubuntu 24.04.2 - wxFilePickerCtrl

[Black Jack]

Hi all.

I built 3.3.0 today, and found error or am I wrong....

wxFilePickerCtrl  returns empty file path. 

Both wxFileName wxFilePickerCtrl::GetFileName()

and wxString wxFilePickerCtrl::GetPath()

Here is minimal demo-app code to reproduce it.

//-------------------------------------------

#include <wx/app.h>
#include <wx/frame.h>
#include <wx/filepicker.h>
#include <wx/filename.h>
#include <wx/textctrl.h>

class MyFrame : public wxFrame
{
    wxFilePickerCtrl* m_filePicker;
    wxTextCtrl* m_textCtrl1;
    wxTextCtrl* m_textCtrl2;
    wxTextCtrl* m_textCtrl3;
    wxTextCtrl* m_textCtrl4;

public:
    MyFrame(wxWindow *parent, int id = wxID_ANY, wxString title = wxT("wx330 FilePicker Error Demo")) : wxFrame(parent, id, title)
    {
        m_filePicker = new wxFilePickerCtrl( this, wxID_ANY, wxEmptyString, wxT("Select a file"), wxT("*.*"), wxPoint(0,0), wxSize( 200,30 ), wxFLP_OPEN );

        m_textCtrl1 = new wxTextCtrl( this, wxID_ANY, wxEmptyString, wxPoint(0, 50), wxSize(100, 30) );
        m_textCtrl2 = new wxTextCtrl( this, wxID_ANY, wxEmptyString, wxPoint(0, 90), wxSize(100, 30) );
        m_textCtrl3 = new wxTextCtrl( this, wxID_ANY, wxEmptyString, wxPoint(0, 130), wxSize(100, 30) );
        m_textCtrl4 = new wxTextCtrl( this, wxID_ANY, wxEmptyString, wxPoint(0, 170), wxSize(100, 30) );

        m_filePicker->Bind( wxEVT_COMMAND_FILEPICKER_CHANGED, &MyFrame::OnFilePickUpChanged, this );
    }

    void OnFilePickUpChanged( wxFileDirPickerEvent& event )
    {
        wxFileName fname = m_filePicker->GetFileName();

        wxString longPath = fname.GetLongPath();
        wxString fullName = fname.GetFullName();
        wxString fnamePath = fname.GetPath();
        wxString pickerPath = m_filePicker->GetPath();

        m_textCtrl1->AppendText(longPath);
        m_textCtrl2->AppendText(fullName);
        m_textCtrl3->AppendText(fnamePath);
        m_textCtrl4->AppendText(pickerPath);
    }

    ~MyFrame(){}
};

class MyApp : public wxApp
{
public:
    virtual bool OnInit()
    {
        MyFrame* frame = new MyFrame(0L);
        frame->Show(true);
        return true;
    }
};

wxIMPLEMENT_APP(MyApp);
//------------------------------------------------------------

Am I doing something wrong or is this really an error?

Yes, unfortunately there is indeed a problem with them, as can be seen on
the "picker" page of the widgets samples. This was possibly introduced by
071b4dd0f1 (Use GtkFileChooserNative for wxFileDialog/wxDirDialog when
possible, 2025-02-09), but I don't see what is wrong immediately, we're
somehow using the wrong widget for getting the path, but I am not sure how
this was actually intended to work.

Please open an issue for it, I'll try to look at it later if nobody else
does.

Thanks,
VZ

I've created https://github.com/wxWidgets/wxWidgets/pull/25591 which
should fix this, please test it if you can.
