Question

所以我尝试关闭一个窗口（不破坏主窗口）的小尝试前进了一点，但击中了另一块石头。代码编译时没有错误或警告，但是当我按下按钮触发“on_window_sidebar1_back_clicked”时，运行该程序的控制台会发出错误"Could not find signal handler 'on_window_sidebar1_back_clicked'. Did you compile with -rdynamic?。

我用-rdynamic运行我的编译器，它没有帮助。

负责关闭窗口的部分代码：

void on_window_sidebar1_back_clicked() 
 {
    void
    gtk_close_window(secondWindow); //sedondWindow is defined further up. no errors related to it.
 }

my window_main.glade（警告！LONG）

我的问题是用户端的错误。我忘了在终端设备上清理构建并且在那里有一些重叠的目录。在移动存储库时，linux决定优先考虑旧存储库。问题得到解决，令人惊讶的是，代码可以运行。

编辑：

我也转而使用

var table = $('#data').DataTable();
$('#data tbody').on('click', 'td.details-control,.addsta,.mjump,.mcon,.delwf', function () {    
    if (this.className == "btn btn-danger delwf") {
    var tr = $(this).closest('tr');
    var row = table.row(tr);
            $scope.sworcode = row.data().worcode;
            $scope.slancode = row.data().lancode;
            console.log(row.data().worcode);
            $scope.$apply();
            $('#modal-del').modal('show');
            };
}

而不是

void on_sidebar1_back_clicked()
 {
    gtk_widget_destroy(GTK_WIDGET(secondWindow));
 }

并将我的信号改为更短，以避免（人类）记忆问题。

GTK C“找不到信号处理程序”。你用-rdynamic编译了吗？
