gtk防止視窗最大化

1.代碼中添加

g_signal_connect(G_OBJECT(window), "configure-event", G_CALLBACK(callback_detect_window_size), NULL);
           

2.回調如下

gboolean callback_detect_window_size(GtkWidget *window, GdkEvent *event, gpointer data)
{
    gint width = event->configure.width;
    gint hight = event->configure.height;
    gint real_width = 0, real_hight = 0;

    if (g_win_kind == WIN_KIND_SECURITYU_MAIN)
    {
        real_width = WIN_MAINBG_WIDTH;
        real_hight = WIN_MAINBG_HIGHT;
    }
    else if(g_win_kind == WIN_KIND_SECURITYU_SET_PWD_POP)
    {
        real_width = WIN_MSG_WIDTH;
        real_hight = WIN_MSG_HIGHT;
    }
    else if(g_win_kind == WIN_KIND_SECURITYU_TRAY)
    {
        real_width = WIN_SETTING_WIDTH;
        real_hight = WIN_SETTING_HIGHT;
    }

    //浮動10像素，是防止系統偵測視窗大小有出入
    if (width > real_width + 10 || hight > real_hight + 10)
    {
        //gtk_widget_set_size_request(window, WIN_SETTING_WIDTH, WIN_SETTING_HIGHT);
        //gtk_widget_hide(window);
        //gtk_widget_show_all(window);

        gtk_window_unmaximize(GTK_WINDOW(window));
    }

    return FALSE;
}
