CodeBlocks wxWidgets-3.2.2.1 compile error

Situation

I am trying to learn a bit of C++ and I am using the IDE Code::Blocks 20.03 32bit (=C::B), wxWidgets-3.2.2.1 and GNU GCC compiler.

I crated a GUI with wxSmith adding wxFrame. Inside it I added some other components (ex: wxSplitterWindows, wxAuiManagers, wxPanes, Checkboxes, textboxes and more).
The following screenshot shows the main tree structure:

C::B on its own generated the relative code of the GUI and among the other lines of code, into the file splitter.h, C::B generated the following function declaration:

void Initialize(wxWindow *window);

and into the file dlgMain.cpp C::B generated the following code:

SplitterWindow->Initialize(AuiManager);

Into the splitter window components I also created Graphically some AuiManagers. For them the IDE C::B automatically created code like the following, of course changing the variable names for each of them:

AuiManager = new wxAuiManager(SplitterWindow, wxAUI_MGR_ALLOW_ACTIVE_PANE|wxAUI_MGR_DEFAULT);

Into some of them I've also created some panels and C::B crated the code as follows also changing automatically the var names as it needed:

AuiManager->AddPane(Panel3, wxAuiPaneInfo().Name(_T("PaneName3")).DefaultPane().Caption(_("3) Caption of the Pane 3 (Auto Sorted Alphanumerically)")).CaptionVisible().MaximizeButton().CloseButton(false).Position(2).Center().Floatable(false).Movable(false).PaneBorder(false));
AuiManager->Update();

The Frame is much more complex of course and has as you can expect multiple files and some thousands lines of total code.

The problem

When I compile the project the compiler returns a couple of errors like the following for :

[filepath]dlgMain.cpp [row number] error: no matching function for call to 'wxSplitterWindow::Initialize(wxAuiManager*&)'
[filepath]splitter.h [row number]  note: candidate: 'void wxSplitterWindow::Initialize(wxWindow*)'
[filepath]splitter.h [row number]  note: no known conversion for argument 1 from 'wxAuiManager*' to 'wxWindow*'

The errors are 2 in total one for each of the following lines of code that C::B compiler indicates into the Built Messages Tab page:

590: SplitterWindowSxVar->Initialize(AuiManagerSxVar);
1253: SplitterWindowDxVar->Initialize(AuiManagerDxVar);

They are contained into the file dlgMain.cpp (a file that is part of the project)

they call the row

102: void Initialize(wxWindow *window);

contained into the file splitter.h

This last file is not part of my project but it is a c++ header file from wxWidgets and it is stored into the following path:

C:\wxWidgets-3.2.2.1\include\wx\generic\splitter.h

I did not create any of the above code manually: C::B created everything automatically while I inserted components into the Frame using the graphic designer wxSmith.

What I have tried:

I changed the line

void Initialize(wxWindow *window);

to

void Initialize(wxAuiManager *window);

without any success so I returned back to the original code.

I also tried to find the implementation of

void Initialize(wxWindow *window);

with no success: I can find just the above line that I suppose should be the declaration, but no track of the implementation itself.

I also deleted the row

SplitterWindow->Initialize(AuiManager);

from the dlgMain.cpp file: after the deletion, the project compiles and executes correctly whit no errors, but the line of code I deleted is regenerated automatically by C::B as soon as the file is updated or closed and reopened for any reason, so the error shows again right after.

Some screenshots that I hope can be helpful

The lines I delete are those indicated by the red rectangle on the left sides, where are the row numbers. But C::B recreates them automatically as already described.

Questions:

1. What is the meaning of the error shown at compile time?
2. Why the line of code that generates the error is regenerated automatically by C::B after I delete it and the project is updated or closed and reopened?
3. Why C::B generates automatically code that generates errors when compiling?
4. What do I do to get rid of the error once and for all?

The error you're getting is simple to understand: wxSplitterWindow::Initialize() requires a window and you're trying to pass it wxAuiManager which is not a window at all, it's something that manages floating/dockable panes inside the window associated with it. It's surprising that C::B allows you to use it as a "component" but this really doesn't make sense and you simply shouldn't do it.

It's a bit harder to suggest what should you actually do instead because it's not clear what would you like to do. Putting AUI panes inside wxSplitterWindow doesn't make much sense because AUI allows you to do much more than just resize the windows, so perhaps you just don't need the splitter at all?
