GTK3 - 從庫存

Question

創建圖像對象我想創建用於顯示錯誤消息的網格，如果該文件不存在：

/* size */ 
s = get_file_size(recording->filename); 
if (s > 0) { 
    size = g_format_size_full(s, G_FORMAT_SIZE_LONG_FORMAT); 
    gtk_label_set_text(GTK_LABEL(size_lbl), size); 
    gtk_widget_hide(error) 
    g_free(size); 
} else { 
    size = g_strdup(_("Import Errors")); 
    gtk_widget_show(error) 
} 

在GTK網格不能設置「錯誤」元件的類型來顯示消息，如屏幕截圖：

grid = gtk_grid_new(); 
gtk_grid_set_row_spacing(GTK_GRID(grid), 6); 
gtk_grid_set_column_spacing(GTK_GRID(grid), 15); 
gtk_container_set_border_width(GTK_CONTAINER(grid), 6); 

s_lbl = gtk_label_new(Size:); 
size_lbl = gtk_label_new(""); 
error = ? 
error_pixmap = gtk_image_new_from_stock(GTK_STOCK_DIALOG_ERROR, GTK_ICON_SIZE_SMALL_TOOLBAR); 
gtk_container_add(GTK_CONTAINER(error), error_pixmap); 

gtk_grid_attach(GTK_GRID(grid), s_lbl, 0, 0, 1, 1); 
gtk_grid_attach(GTK_GRID(grid), error, 1, 0, 1, 1); 
gtk_grid_attach(GTK_GRID(grid), size_lbl, 2, 0, 1, 1); 

對於任何幫助，謝謝。

使用GtkBox與GTK_ORIENTATION_HORIZONTAL，或在GtkGrid相鄰的單元格。
