VS2022 reporting wxMenu memory leak Topic is solved

[rkamarowski]

Windows 11
Visual Studio 2022
C++
wxWidgets 3.2.0

I have the following code in my wxFrame:

Code: Select all

wxMenu* fileMenu = new wxMenu();

If I close the app by clicking the 'X' in the upper right hand corner of the window VS2022 is reporting memory leaks. If I close app using the red Stop Debugging button there are no memory leaks reported. If I comment out the above line of code no leaks are reported either way the app is closed.

Am I having memory leaks, and why?
Thank you,

That's not enough code. If the menu is added to a wxMenuBar, and that wxMenuBar is attached to the wxFrame, there should be no memory leak.

Check the "minimal" sample that comes with the wxWidgets source code for reference.

Code: Select all

#include "PMainFrame.h"

using namespace pWidgets;


PMainFrame::PMainFrame()
	: wxFrame(NULL, wxID_ANY, "EES Photography", wxPoint(10,10))
{
	OnInit();
}

void PMainFrame::OnInit()
{
	Bind(wxEVT_MENU, &PMainFrame::OnAbout, this, TEXT_ABOUT);
	Bind(wxEVT_MENU, &PMainFrame::OnExit, this, TEXT_EXIT);

	SetMinSize(wxSize(800, 600));
	SetSize(100, 100, 900, 700);
	Center(wxBOTH);

	wxMenu* fileMenu = new wxMenu();
	fileMenu->AppendSeparator();
	fileMenu->Append(TEXT_EXIT, wxT("E&xit"), wxT("Exit application"));

	wxMenu* routineMenu = new wxMenu();
	routineMenu->Append(ROUTINE_EDIT, wxT("&Edit routine"),
		wxT("Edit routine."));
	routineMenu->Append(ROUTINE_EXECUTE, wxT("&Run routine"),
		wxT("Run routine."));

	wxMenu* aboutMenu = new wxMenu;
	aboutMenu->Append(TEXT_ABOUT, wxT("&About"));

	wxMenuBar* menuBar = new wxMenuBar(wxMB_DOCKABLE);
	menuBar->Append(fileMenu, wxT("&File"));
	menuBar->Append(aboutMenu, wxT("&About"));

	SetMenuBar(menuBar);
}

void PMainFrame::OnExit(wxCommandEvent& event)
{
	Close(true);
}

You're not adding routineMenu to the menubar.

Ugh... As always, thank you doublemax. Hopefully next time it will be something more interesting
