Socket events not processed when user moves or resizes window

Postby kurtNovoselic » Fri May 11, 2018 7:25 pm

I have this problem working with socket events, I'm receiving data from TCP client handling reception with events.
It works fine, I process data from client and then show a message in wxTextCtrl (multiline) with information for user.
But when I move window or select text in wxTextCtrl my app doesn't send any kind of data to client.
I'm not working with secondary threads for this at the moment.

Code: Select all

BEGIN_EVENT_TABLE(ServerDialog,wxDialog)
    //(*EventTable(ServerDialog)
    //*)
    EVT_BUTTON(ID_BTNHIDE,  ServerDialog::ClickHide)
    EVT_BUTTON(ID_BTNEXIT,  ServerDialog::OnQuit)
    EVT_CLOSE(ServerDialog::OnCloseWindow)
    EVT_BUTTON(ID_BTNSTART, ServerDialog::OnServerStart)
    EVT_SOCKET(SERVER_ID,  ServerDialog::OnServerEvent)
    EVT_SOCKET(SOCKET_ID_WEB, ServerDialog::OnSocketEventWeb)
    EVT_SOCKET(SOCKET_ID_REG, ServerDialog::OnSocketEventReg)
END_EVENT_TABLE()


Function working with event EVT_SOCKET(SOCKET_ID_REG, ServerDialog::OnSocketEventReg):

Code: Select all

void ServerDialog::OnSocketEventReg(wxSocketEvent& event)
{
    // The socket that had the event
    wxSocketBase* sock = event.GetSocket();

    switch(event.GetSocketEvent())
    {
        case wxSOCKET_CONNECTION:
            break;

        case wxSOCKET_INPUT:
        {
            /****************************************************************************************************************************/
            char buf[10] = {0,0,0,0,0,0,0,0,0,0};
            wxDateTime dt = wxDateTime().Now();
            //Formatear texto de hora y fecha para enviar al servidor...
            wxString strdt = dt.Format("%H:%M:%S %d/%m/%y");
            sock->Read(buf, sizeof(buf)-1);   // Se reciben máximo 9 caracteres (se deja espacio para \0)

            char c1er_ = buf[0];
            // "(tipo)(space)(d1d2d3d4)" 6 caracteres + 1 nulo => máximo = 7
            // Verificar integridad de formato de peso...
            if((c1er_ == 'A' || c1er_ == 'B' || c1er_ == 'C' || c1er_ == 'D')  && buf[1]== ' ' && sock->LastCount() <= 7)
            {
                wxString str_peso = &buf[2];
                if(str_peso.IsNumber())
                {
                    // Registro normal...

I was searching in forum and something like this viewtopic.php?t=42379 sounds similar.

Platform. wxWidgets version?

If you're using wx 3.0.3 or older, please try with the latest version from GIT.
Use the source, Luke!

Hi,
Do you handle any mouse events?
Can you reproduce the behaviour in the socket samples (client/server)?

Thank you.

No.. I am not handling any mouse events....
I'll try with the socket samples...

Hi,
This is actually means it is a regression in wx 3.1.
For testing purposes - can you try to build Git HEAD (latest master) and see if its reproducible there?

Also, I strongly advise you to check the samples on 3.1 and see if you can reproduce it there. Because if you can it means it is an actual regression and it has to be fixed.

So if you still have 3.1 sources available - please try with the sample. If it produces the same behaviour - please file a bug on trac.wxwidgets.org. Say wx version, OS version, compiler version and steps to reproduce the issue.

Hopefully Vadim will try to see what is happening.

Thank you.
