    <p>I've done a little program in C with GTK with a window, a box and a table inside the box. The table is painted with some files. I'd like to refresh the table with other data but I don't know how.</p> <p>This code launches a window with a <code>GtkTable</code>. This table is filled in the timer handle function. First time draw three lines in order 1,2,3 and last time write three lines in order 3,2,1. But the table never refreshes.</p> <pre><code>#include &lt;stdlib.h&gt; #include &lt;gtk/gtk.h&gt; static gboolean time_handler(GtkWidget *table); gboolean launched; int main( int argc, char *argv[]) { GtkWidget *window; GtkWidget *vboxgeneral; gchar *title; GtkWidget *table; gtk_init(&amp;argc, &amp;argv); /* WINDOW */ window = gtk_window_new(GTK_WINDOW_TOPLEVEL); title = "Test GtkTable"; gtk_window_set_title(GTK_WINDOW(window), title); gtk_window_set_default_size(GTK_WINDOW(window), 200, 100); gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER); /* ADDING GTKHBOX TO MAIN WINDOW */ vboxgeneral = gtk_vbox_new(FALSE, 0); /* ADDING GTKTABLE TO VBOX */ table = gtk_table_new(1,1,FALSE); gtk_box_pack_start(GTK_BOX(vboxgeneral), table, FALSE, FALSE, 0); /* SHOW ALL */ gtk_widget_show_all(window); /* ACTIONS */ g_signal_connect_swapped(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL); /* START TIMER */ g_timeout_add(10000, (GSourceFunc) time_handler, (gpointer) window); time_handler(table); gtk_main(); return 0; } static gboolean time_handler(GtkWidget *table) { GtkWidget *widget; gboolean result = FALSE; /* ADDING TABLE DEFINITION */ if(!launched) { table = gtk_table_new(3,1,FALSE); widget = gtk_label_new("File 1"); gtk_label_set_justify(GTK_LABEL(widget), GTK_JUSTIFY_CENTER); gtk_table_attach_defaults (GTK_TABLE (table), widget, 0, 1, 0, 1); widget = gtk_label_new("File 2"); gtk_label_set_justify(GTK_LABEL(widget), GTK_JUSTIFY_CENTER); gtk_table_attach_defaults (GTK_TABLE (table), widget, 0, 1, 1, 2); widget = gtk_label_new("File 3"); gtk_label_set_justify(GTK_LABEL(widget), GTK_JUSTIFY_CENTER); gtk_table_attach_defaults (GTK_TABLE (table), widget, 0, 1, 2, 3); launched = TRUE; result = TRUE; g_print("Timer executed fisrt time!\n"); } else { table = gtk_table_new(3,1,FALSE); widget = gtk_label_new("File 3"); gtk_label_set_justify(GTK_LABEL(widget), GTK_JUSTIFY_CENTER); gtk_table_attach_defaults (GTK_TABLE (table), widget, 0, 1, 0, 1); widget = gtk_label_new("File 2"); gtk_label_set_justify(GTK_LABEL(widget), GTK_JUSTIFY_CENTER); gtk_table_attach_defaults (GTK_TABLE (table), widget, 0, 1, 1, 2); widget = gtk_label_new("File 1"); gtk_label_set_justify(GTK_LABEL(widget), GTK_JUSTIFY_CENTER); gtk_table_attach_defaults (GTK_TABLE (table), widget, 0, 1, 2, 3); result = FALSE; g_print("Timer executed last time!\n"); } gtk_widget_draw(table, NULL); return result; } </code></pre>

    1. COYou put your data in the table in `fill_data()`, but you didn't include that function here. On the other hand, you included lots of code that is irrelevant to the problem. Can you create a minimal example that shows what you want to do?

    3. COThanks! Only please don't remove your original question, or the question won't make sense in the future. I edited it to put the original question back at the top.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
