GTK warning from codelite generated code

[martynwheeler]

Hi,

I hope that this the right place to ask about this. I have been experimenting with codelite. I have set up a simple project and am getting a warning in the console.

Code: Select all

(HelloWorld:76497): Gtk-CRITICAL **: 19:36:17.469: gtk_window_resize: assertion 'height > 0' failed

wxCrafter automatically generated c++ code for the gui and here it is:

Code: Select all

// Declare the bitmap loading function
extern void wxC9ED9InitBitmapResources();

static bool bBitmapLoaded = false;


MainFrameBaseClass::MainFrameBaseClass(wxWindow* parent, wxWindowID id, const wxString& title, const wxPoint& pos, const wxSize& size, long style)
    : wxFrame(parent, id, title, pos, size, style)
{
    if ( !bBitmapLoaded ) {
        // We need to initialise the default bitmap handler
        wxXmlResource::Get()->AddHandler(new wxBitmapXmlHandler);
        wxC9ED9InitBitmapResources();
        bBitmapLoaded = true;
    }
    
    wxBoxSizer* boxSizer1 = new wxBoxSizer(wxVERTICAL);
    this->SetSizer(boxSizer1);
    
    m_mainPanel = new wxPanel(this, wxID_ANY, wxDefaultPosition, wxDLG_UNIT(this, wxSize(-1,-1)), wxTAB_TRAVERSAL);
    
    boxSizer1->Add(m_mainPanel, 1, wxEXPAND, WXC_FROM_DIP(5));
    
    m_menuBar = new wxMenuBar(0);
    this->SetMenuBar(m_menuBar);
    
    m_name6 = new wxMenu();
    m_menuBar->Append(m_name6, _("File"));
    
    m_menuItem7 = new wxMenuItem(m_name6, wxID_EXIT, _("Exit\tAlt-X"), _("Quit"), wxITEM_NORMAL);
    m_name6->Append(m_menuItem7);
    
    m_name8 = new wxMenu();
    m_menuBar->Append(m_name8, _("Help"));
    
    m_menuItem9 = new wxMenuItem(m_name8, wxID_ABOUT, _("About..."), wxT(""), wxITEM_NORMAL);
    m_name8->Append(m_menuItem9);
    
    m_mainToolbar = this->CreateToolBar(wxTB_FLAT, wxID_ANY);
    m_mainToolbar->SetToolBitmapSize(wxSize(16,16));
    
    SetName(wxT("MainFrameBaseClass"));
    SetSize(wxDLG_UNIT(this, wxSize(800,400)));
    if (GetSizer()) {
         GetSizer()->Fit(this);
    }
    if(GetParent()) {
        CentreOnParent(wxBOTH);
    } else {
        CentreOnScreen(wxBOTH);
    }
#if wxVERSION_NUMBER >= 2900
    if(!wxPersistenceManager::Get().Find(this)) {
        wxPersistenceManager::Get().RegisterAndRestore(this);
    } else {
        wxPersistenceManager::Get().Restore(this);
    }
#endif
    // Connect events
    this->Connect(m_menuItem7->GetId(), wxEVT_COMMAND_MENU_SELECTED, wxCommandEventHandler(MainFrameBaseClass::OnExit), NULL, this);
    this->Connect(m_menuItem9->GetId(), wxEVT_COMMAND_MENU_SELECTED, wxCommandEventHandler(MainFrameBaseClass::OnAbout), NULL, this);
    
}

MainFrameBaseClass::~MainFrameBaseClass()
{
    this->Disconnect(m_menuItem7->GetId(), wxEVT_COMMAND_MENU_SELECTED, wxCommandEventHandler(MainFrameBaseClass::OnExit), NULL, this);
    this->Disconnect(m_menuItem9->GetId(), wxEVT_COMMAND_MENU_SELECTED, wxCommandEventHandler(MainFrameBaseClass::OnAbout), NULL, this);
    
}

The lines that are triggering the warning are;

Code: Select all

if (GetSizer()) {
GetSizer()->Fit(this);
}

If i remove these then the warning goes away. The program works, but I was just wondering why this warning was coming about and if anyone knows how to fix it without manually removing those lines?

Thank you in advance,

Martyn

Hi,

Recent versions of GTK+ have the unfortunate habit of emitting (some might say 'spamming') many such calls. They are almost always false alarms, in that they cause no noticeable problems.

If a program builds and runs successfully, just ignore them.
