当调整窗口大小时，应用程序在windows 8.1上崩溃。

Question

大约一年前，我在视频工作室开发了一个gtkmm应用程序。当我有Windows和Visual 2010时，没有问题。现在，当我一年后在windows 8.1上运行并在Visual 2012中编译时，我可以启动它，但只要我试图调整窗口大小或按OK按钮，它就会崩溃。

在调试器中，当调整窗口大小时，我可以在这里看到它在回调函数中崩溃：

cr = window->create_cairo_context();

在这里按ok按钮时：

} 

这是回调函数返回时的末尾。

下面是源代码(回调函数)

 void MyWindow::on_button_clicked(Glib::ustring data) {

Glib::RefPtr<Gdk::Window> window = myDrawingArea.get_window();

if(window)
{

    Gtk::Allocation allocation = myDrawingArea.get_allocation();
    const int width = allocation.get_width();
    const int height = allocation.get_height();
    std::cout << "w = " << width << std::endl;

    // coordinates for the center of the window
    int xc, yc;
    xc = width / 2;
    yc = height / 2;

    Cairo::RefPtr<Cairo::Context> cr = window->create_cairo_context();

    cr->set_line_width(1.0);
    std::cout << "hello in on_button_clicked!!!\n";

    a = 0;
    b = 300;
    c = 200;
    d = 150;
    e = 350;
    f = 400;
    // draw red lines out from the center of the window
    cr->set_source_rgb(0.8, 0.5, 0.0);
    cr->move_to(a, b);
    cr->line_to(c, d);
    cr->move_to(c, d);
    cr->line_to(e, f);

    cr->stroke();
    std::cout << "here comes crasch!!!\n";
}

另一个(调整大小)

 bool MyWindow::on_drawing_expose_event(GdkEventExpose* event) {

Glib::RefPtr<Gdk::Window> window = myDrawingArea.get_window();
if(window)
{
    std::cout << "here comes crasch!!!\n";
        cr = window->create_cairo_context();

调试器给了我这个信息

    sigc::trackable <Unable to read memory> 
    Glib::ObjectBase    <Unable to read memory> 

以及调用堆栈

所以我想知道有什么问题--因为它过去在另一个平台上运行时没有问题？

很好地寻求帮助。如果有人想看整个来源，并尝试它，我可以张贴它。

Answer 1

您的问题是编译器版本，您需要使用Visual 2013从源代码编译新的gtkmm，然后重新构建应用程序。

第二个选择是安装旧版本的Visual，并重新构建应用程序和目标XP。

如果您决定使用Visual 2013编译最新的gtkmm (3.14)，我编写了一个教程link1 link2来说明如何做到这一点。无论如何，在我的GitHub页面上，您还可以找到prebult gtkmm 3.14 for Visual 2013调试for x64
