How to Privent wxFrame from Move and stay it maxsized

Post by cutecode »

Создал киоск на линуксе с единственным приложением типа wxFrame.

Убрал у него заголовок и убрал стиль для изменения его размера мышкой.

Проблема теперь в том что menueBar ведет себя как заголовок, т.е. если схвачу его мышкой и начинаю тащить мышку, то окно перемещается
и отображает рабочий стол.

Рабочий стол конечно же пустой, но хотелось бы убрать такое странное поведение программно не извращаясь с настройками самого линукс.


Функци типа OnWindowMove я в хэлпах не нашел

Спасибо

Есть wxMoveEvent. Можно попробовать в обработчике возвращать окно на место.

Если использую

Code: Select all

ShowFullScreen(true);
то вроде то что надо, но зато не могу открыть другие дочерние wxFrame, они прячутся за главной wxFrame

если пишу так

Code: Select all

        ShowFullScreen(true, wxFULLSCREEN_NOBORDER | wxFULLSCREEN_NOCAPTION);
то опять же меню ведет себя снова как заголовок

заметил что такое поведеение только для GTK3, у gtk2 такого поведения нет.

Придется пробовать перехват сообщений wxMoveEvent.


Спасибо

версия gtk3 стандартная в debian 10, и обновлять ее не хочу.
Ибо хочу сделать все программно, чтоб работало везде одинаково.

С wxMoveEvent все получилось
спасибо

Обнаружил проблему с wxMoveEvent
Прога "жрет" процессор на 100%. оказалось, что при установке позиции окна в wxPoint(0, 0)
опять вызывается wxMoveEvent, и так все в цикле один вызов вызывает другой вызов рекурсивно.
Как лучше предотвращать перемещения окна?

Code: Select all

void MyFrame::OnFrameMove2()
{
    wxPoint pt(0, 0);
    SetPosition(pt);
}

void MyFrame::OnFrameMove(wxMoveEvent& event)
{
    if (GetIsKiosk() || GetIsDemo() || GetIsTerminal())
    {
        CallAfter(&MyFrame::OnFrameMove2);
        event.Skip(0);
    }
}
Спасибо

Read the position of the window first, and if it's already at (0,0), don't call SetPosition().
Use the source, Luke!

As sugested here viewtopic.php?f=1&t=26794&p=114388&hili ... nt#p114388
I set timer for every wxMoveEvent

This code is working, and prcessor is taking 85% only for 5-10 seconds

Code: Select all

void MyFrame::OnFrameMove2()
{
    printf("OnFrameMove2\n");

    int x, y;
    GetPosition(&x, &y);

    if(x || y)
    {
        printf("%dx%d\n", x, y);

        wxPoint pt(0, 0);
        SetPosition(pt);

        GetPosition(&x, &y);
        printf("%dx%d\n", x, y);
    }
}

void MyFrame::OnFrameMove(wxMoveEvent& event)
{
    printf("OnFrameMove\n");
	if (GetIsKiosk() || GetIsDemo() || GetIsTerminal())
    {
        if (mvTimer)
        {
            if (mvTimer->IsRunning())
                mvTimer->Stop();

            mvTimer->Start(1000, true);
        }
    }
}

void MyFrame::onMoveWindowEnd(wxTimerEvent& event)
{
    CallAfter(&MyFrame::OnFrameMove2);
}
and log looks like

Code: Select all

I guess the problem is that each SetPosition() call also generates a Move event. Try setting a flag before calling SetPosition(), and if the flag is set inside the Move event handler, do nothing.

BTW: is it really so under Linux that you can move a window when it's maximized? Under Windows that's impossible, event if the caption bar is visible.

This won't help.
After calling SetPosition() - OnFrameMove() is called twice.
The first time immediately after calling SetPosition(), and second time after exiting from OnFrameMove2()

Not sure if this behaver would be all linux distributions

The only solution I see, is setting the flag twice.
Just tested on windows, move event is called twice too, after setting SetPissition()

Code: Select all

        wxPoint pt(0, 0);
        m_nIsMoving++;
        SetPosition(pt);

        m_nIsMoving++;
    }
}

void MyFrame::OnFrameMove(wxMoveEvent& event)
{
    if(m_nIsMoving > 0)
    {
        m_nIsMoving--;
        return;
    
    }
    
    ...
