用GtkTreeView实现ListBox示例

前段时间花了不少时间去研究GTK+的架构,但没有怎么关注具体控件的使用。大部控件都有示例代码,相信使用不会很难。今天要测试一下用GtkTreeView实现ListBox,发现没有GtkTreeView的示例代码,GTK+的tutorial里也没有讲解。只好自己折腾,结果花了两个小时才搞定,写段代码做个备忘吧。
GtkWidget* create_window1 (void) { GtkWidget *window1; GtkWidget *scrolledwindow1; GtkWidget *treeview1; GtkTreeViewColumn* column; GtkTreeIter iter; GtkListStore* store; GtkCellRenderer* cell;
char text[32] = {0}; int i = 0 ; int n = 100;
window1 = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_title (GTK_WINDOW (window1), _("window1"));
scrolledwindow1 = gtk_scrolled_window_new (NULL, NULL); gtk_widget_show (scrolledwindow1); gtk_container_add (GTK_CONTAINER (window1), scrolledwindow1); gtk_scrolled_window_set_shadow_type (GTK_SCROLLED_WINDOW (scrolledwindow1), GTK_SHADOW_IN);
treeview1 = gtk_tree_view_new (); column = gtk_tree_view_column_new(); gtk_tree_view_append_column(GTK_TREE_VIEW(treeview1), column);
cell = gtk_cell_renderer_text_new(); gtk_tree_view_column_pack_start(column, cell, TRUE); gtk_tree_view_column_set_attributes(column, cell, "text", 0, NULL);
column = gtk_tree_view_column_new(); gtk_tree_view_append_column(GTK_TREE_VIEW(treeview1), column);
store = gtk_list_store_new(1, G_TYPE_STRING); gtk_tree_view_set_model(treeview1, GTK_TREE_MODEL(store));
for(i = 0; i < n; i ++) { sprintf(text, "text%d", i); gtk_list_store_append(store, &iter); gtk_list_store_set(store, &iter, 0, text, -1); }
gtk_widget_show (treeview1); gtk_container_add (GTK_CONTAINER (scrolledwindow1), treeview1);
/* Store pointers to all widgets, for use by lookup_widget(). */ GLADE_HOOKUP_OBJECT_NO_REF (window1, window1, "window1"); GLADE_HOOKUP_OBJECT (window1, scrolledwindow1, "scrolledwindow1"); GLADE_HOOKUP_OBJECT (window1, treeview1, "treeview1");
return window1; } |

得到选中项的内容:
void on_button1_clicked (gpointer user_data, GtkButton *button) { GValue value = {0}; GtkTreeIter iter = {0}; GtkTreeStore* store = NULL; GtkTreeSelection* selection = NULL; GtkTreeView* treeview = NULL;
treeview = (GtkTreeView*)lookup_widget(GTK_WIDGET(user_data), "treeview1"); selection = gtk_tree_view_get_selection(treeview); gtk_tree_selection_get_selected(selection, (GtkTreeModel**)&store, &iter); gtk_tree_model_get_value(GTK_TREE_MODEL(store), &iter, 0, &value);
g_debug("%s/n", g_value_get_string(&value));
return ; } |
