I know a hack way to do this, but wonder why you would want to.
Anyway the table struct contains a GList holding all of the child widgets as seen below:
struct _GtkTable
{
GtkContainer container;
GList *children;
GtkTableRowCol *rows;
GtkTableRowCol *cols;
guint16 nrows;
guint16 ncols;
guint16 column_spacing;
guint16 row_spacing;
guint homogeneous : 1;
};
if you have the pointer of the widget you would like to remove you could do this:
GtkWidget *table;
GtkWidget *old_label;
GtkWidget *temp;
GtkWidget *new_label;
GList *children;
new_label = gtk_label_new("new label");
children = g_list_first(GTK_TABLE(table)->children);
while (children) {
temp = children->data;
children = children->next;
if (temp == old_label) {
temp = new_label;
gtk_widget_destroy (old_label);
break;
}
}
the code would replace the widget pointer but you may need to queue a resize and a draw to get it to appear,
and this is an evil hack if ever there were one.
