Return code -11 when performing SetSizerandFit

[philm]

Hello all,

I ahev ran into an issue that I can't seem to figure out. The solution is not quite obvious.

So right now, I have 1 frame and 2 panels. The first panel, has 2 buttons in it. When the user clicks on one of the two buttons, the first panel will be deleted and the second one will be created with a few more controls in it (a listbox, static text, and 2 buttons)

Currently, here is a working version of the code for the first panel:

Code: Select all

    wxBoxSizer *buttonSizer = new wxBoxSizer(wxHORIZONTAL);

	// This seciton will create a new panel and apply 2 buttons on the panel. 
	// The 2 buttons are associated with the panel and when the panel is destoryed, so are the buttons.
	_initialStartPanel->Create(this, wxID_ANY);
	
	wxButton *buttonNewFile = new wxButton(_initialStartPanel, buttonID::ID_buttonNew, "New", wxDefaultPosition, wxSize(75, 23));
	wxButton *buttonOpenFile = new wxButton(_initialStartPanel, buttonID::ID_buttonOpen, "Open", wxDefaultPosition, wxSize(75, 23));
    
    buttonSizer->Add(buttonNewFile, 0, wxALL, 6);
    buttonSizer->Add(buttonOpenFile, 0, wxTOP | wxBOTTOM | wxRIGHT, 6);

    _initialStartPanel->SetSizer(buttonSizer);
    
    SetSizerAndFit(buttonSizer);
    buttonSizer->Fit(_initialStartPanel);
    
    this->SetSize(_initialStartPanel->GetSize());
    this->SetMaxSize(this->GetSize());

    _UIState = systemState::INITIAL_START_UP;

Here is the code for the second panel:

Code: Select all

    wxPanel *problemSelectPanel = new wxPanel();
    wxBoxSizer *footerSizer = new wxBoxSizer(wxHORIZONTAL);
    wxBoxSizer *topSizer = new wxBoxSizer(wxVERTICAL);

	problemSelectPanel->Create(this, wxID_ANY);
	
    wxStaticText *text = new wxStaticText(problemSelectPanel, wxID_ANY, "Select Physics Problem:");
    text->SetFont(*font);
    
    _physicsProblemsListBox->Create(problemSelectPanel, generalFrameButton::ID_LISTBOX, wxDefaultPosition, wxDefaultSize, arrayPhysicsProblem, wxLB_SINGLE); 
    
    topSizer->Add(text, 0, wxALL | wxALIGN_LEFT, 6);
    topSizer->Add(_physicsProblemsListBox, 0, wxLEFT | wxRIGHT | wxBOTTOM | wxALIGN_LEFT, 6);
    
	wxButton *backButton = new wxButton(problemSelectPanel, buttonID::ID_buttonBack, "Back", wxDefaultPosition, wxSize(75, 23));
	wxButton *finishButton = new wxButton(problemSelectPanel, buttonID::ID_buttonFinish, "Finish", wxDefaultPosition, wxSize(75, 23));
    
    footerSizer->Add(backButton, 0, wxCENTER | wxLEFT | wxRIGHT | wxBOTTOM, 6);
    footerSizer->Add(finishButton, 0, wxCENTER | wxBOTTOM | wxRIGHT, 6);
    
    topSizer->Add(footerSizer, 0, wxALIGN_RIGHT);
    
    problemSelectPanel->SetSizer(topSizer);
    
    SetSizerAndFit(topSizer, false);// The error is here!
    topSizer->Fit(problemSelectPanel);
    
    this->SetSize(problemSelectPanel->GetSize());
    this->SetMaxSize(problemSelectPanel->GetSize());
    
    _UIState = systemState::PHYSICS_CHOOSING;

Interestingly enough, when bypass the first panel and have the second panel draw first, everything is all good. No error codes.

I have a suspicion that something is not being properly destroyed when the frame transitions between panels. But I thought that when you call the destroy function for the panel, it destroys everything including sizers. Is this correct or is there something that I have to do special with the sizers?

First of all, you have way too much code for such a question. For example, any wxFont-related code is completely irrelevant here.
As your first attempt at solving this, you need to remove all irrelevant code and maybe already see what is wrong and where.

Code: Select all

    _initialStartPanel->SetSizer(buttonSizer);
    
    SetSizerAndFit(buttonSizer);

Code: Select all

    problemSelectPanel->SetSizer(topSizer);
    
    SetSizerAndFit(topSizer, false);// The error is here!

You are not allowed to set the same sizer to more than one window.

Hello Catalin,

Thank you for the advice and tip. I am looking to improve my posts whereever I go. Sometimes, I might put in more detail then needed but I want to make sure that who ever reads the post will be on the same page as I.

I have now truncated the code to display mainly the relevent parts.

I am currently not at my computer with the code, but once I am avaiable, I will give it a shot. I am still learning how to work with sizers. I made about 8 dialog boxes with them previousely so I hae some experience. I am currently learning how I can use them in a panel. Previousely, I would create everything on a dialog window. Now, I am using panels on a frame.

So I am thinking, would it be better to call:

Code: Select all

problemSelectPanel->SetSizerAndFit(topSizer);
