我在c中使用GTK 2.2.我可以从其中一个条目中获取文本并使用类型转换将其转换为整数,但它不适用于第二个条目.我设置为从第二个条目获取文本的变量由于某种原因保持为0.这是我的代码.button2_clicked部分无效,但问题也可能出在button2 g_signal connect中.

#include <stdlib.h>

    gtk_window_set_position (GTK_WINDOW (dialog), GTK_WIN_POS_CENTER);
    gtk_dialog_run (GTK_DIALOG (dialog));
    gtk_widget_destroy (dialog);
}

static void button2_clicked(GtkWidget *widget,gpointer data){
    amt = (int)gtk_entry_get_text(GTK_ENTRY(data));
    prod_amt = prod;
    int products[10];
    products[0] = 15;
    products[1] = 200;
    products[2] = 55;
    products[3] = 30000;
    products[4] = 15000;
    products[5] = 20000;
    products[6] = 20;
    products[7] = 30;
    products[8] = 2500;
    products[9] …
