用C语言将参数从ComboBox传递给GTKTreeView

#include <gtk/gtk.h>

// 回调函数，处理ComboBox的选中项改变事件
void on_combo_changed(GtkComboBox *combo, gpointer user_data) {
    GtkTreeIter iter;
    GtkTreeModel *model;
    gchar *selected_param;

    // 获取选中的参数值
    model = gtk_combo_box_get_model(combo);
    gtk_combo_box_get_active_iter(combo, &iter);
    gtk_tree_model_get(model, &iter, 0, &selected_param, -1);

    // 将参数值传递给TreeView的数据模型
    // 这里假设TreeView的数据模型是TreeStore类型
    GtkTreeStore *store = GTK_TREE_STORE(user_data);
    gtk_tree_store_append(store, &iter, NULL);
    gtk_tree_store_set(store, &iter, 0, selected_param, -1);

    // 刷新TreeView
    // 这里假设TreeView的指针是tree_view
    GtkTreeModel *new_model = GTK_TREE_MODEL(store);
    gtk_tree_view_set_model(GTK_TREE_VIEW(tree_view), new_model);
}

int main(int argc, char *argv[]) {
    // 初始化GTK+
    gtk_init(&argc, &argv);

    // 创建主窗口和布局
    GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    GtkWidget *vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 5);
    gtk_container_add(GTK_CONTAINER(window), vbox);

    // 创建ComboBox和TreeView
    GtkWidget *combo = gtk_combo_box_new_text();
    GtkWidget *tree_view = gtk_tree_view_new();

    // 添加选项到ComboBox
    gtk_combo_box_append_text(GTK_COMBO_BOX(combo), "参数1");
    gtk_combo_box_append_text(GTK_COMBO_BOX(combo), "参数2");
    gtk_combo_box_append_text(GTK_COMBO_BOX(combo), "参数3");

    // 设置ComboBox的回调函数
    g_signal_connect(combo, "changed", G_CALLBACK(on_combo_changed), NULL);

    // 创建TreeView的数据模型
    GtkTreeStore *store = gtk_tree_store_new(1, G_TYPE_STRING);
    gtk_tree_view_set_model(GTK_TREE_VIEW(tree_view), GTK_TREE_MODEL(store));

    // 创建TreeView的列
    GtkTreeViewColumn *column = gtk_tree_view_column_new();
    gtk_tree_view_column_set_title(column, "参数");
    gtk_tree_view_append_column(GTK_TREE_VIEW(tree_view), column);
    GtkCellRenderer *renderer = gtk_cell_renderer_text_new();
    gtk_tree_view_column_pack_start(column, renderer, TRUE);
    gtk_tree_view_column_add_attribute(column, renderer, "text", 0);

    // 将ComboBox和TreeView添加到布局中
    gtk_box_pack_start(GTK_BOX(vbox), combo, FALSE, FALSE, 0);
    gtk_box_pack_start(GTK_BOX(vbox), tree_view, TRUE, TRUE, 0);

    // 显示窗口和运行主循环
    gtk_widget_show_all(window);
    gtk_main();

    return 0;
