This is the same MyPanel.cpp code, written in wxWidgets and ran in Windows and Linux. I don't have an special "Windows" code, I ran this same code in Windows and I catch the event.
You can google this "When a child window is disabled, Windows passes the child's mouse input messages to the parent window".
Or read here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms632599%28v=vs.85%29.aspx "When a child window is disabled, the system passes the child's mouse input messages to the parent window"

What I am trying to do is: Add a child window like wxTextCtrl and being able to configure/drag/resize/overpaint when in "editable mode", and let it do its own behavior when in "run mode". So "disabling" the control temporarily is convenient, and worked fine when running it in Windows. Not sure why it works, I assumed because it says in Windows "When a child window is disabled, the system passes the child's mouse input messages to the parent window", but maybe there is something else that is affecting and I don't know.
What part of the code you want me to show. The frame that has the panel? I copied the "pWnd3 window" sample because I was able to reproduce it with this simple test. I also tested by adding the table event directly to my wxApp and catch the event there, and the same happened, the event is caught while running it in Windows, but not while running it in Linux.

MyPanel.h:

MyPanel(wxWindow* parent, wxWindowID id = wxID_ANY, const wxString& title = wxT(""), const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize,
long style = wxDEFAULT_FRAME_STYLE|wxTAB_TRAVERSAL|wxCLIP_CHILDREN);

MyPanel .cpp :
========
BEGIN_EVENT_TABLE(MyPanel, wxPanel)
EVT_LEFT_DOWN(MyPanel::OnMouseLeftDown)
END_EVENT_TABLE()
=========

MyPanel::MyPanel(wxWindow* parent, wxWindowID id, const wxString& title,
const wxPoint& pos, const wxSize& size, long style)
: wxPanel(parent, id, pos, size, style, title)
{
wxWindow *pWnd3 = new wxWindow(this, wxID_ANY, wxPoint(220,220), wxSize(100, 100));
pWnd3->Disable();
}

void MyPanel::OnMouseLeftDown(wxMouseEvent &event)
{
// when running in Windows of course the event.Object is the MyPanel window as I expected.
int ltest;
ltest = 1;
}

If I set a break point on the OnMouseLeftDown method.
if I run the program and click on the child window area on the screen, in Windows it hits the break point, in Linux it does not.
Thank you.

Thank you for your time. I have exactly the same wxWidgets code. When I run it in Windows, I get the event in the parent window when I click on a disabled window. When I run it in Linux the parent does not get the event.

I tested in Windows, and it does work fine in Windows.
From Windows documentation:
"Messages : The system passes a child window's input messages directly to the child window; the messages are not passed through the parent window. The only exception is if the child window has been disabled by the EnableWindow function. In this case, the system passes any input messages that would have gone to the child window to the parent window instead. This permits the parent window to examine the input messages and enable the child window, if necessary"

What I really have is a wxPanel, with my wxWindow derived class children, let's call it "Class1".

"Class1" is serves as a base class for any window with any type of Control in it, for example a wxGrid or wxTextCtrl, or my own painted window.

My Class1 handles all mouse events for any type of child windows derived from it, it also allows me to overpaint whatever I want over the controls. It handles all the drag, resize, overpaint, etc.

When I switch my "Class1" window to "configurable" mode, the control is disabled and I can drag, move, resize, and overpaint in Windows.

I did not want to use bitmaps on painting, resizing, etc, for several reasons, but if this is the only way I guess I will need to do it. I was thinking that there could be a way like in Windows, to pass the keyboard input messages to the parent when the window was disabled. This works fine in Windows, but not in Linux.
