Hi Vivien!
For to compute the total height of a treeview based on the
amount of rows its model has, I've tried with the following
code but I had to set some constants that obviously works in my
specific setting but I would like to know to what correspond
that unknowns.
I couldn't find any info about how to do that.
Besides, being that the header window in the treeview is private,
I've tested a very very rude method of obtaining the header size.
(PS treeview must be realized).
----------------------------------------------------------------
static gint
get_header_height (GtkTreeView *tree_view)
{
gtk_tree_view_set_headers_visible (GTK_TREE_VIEW(tree_view), TRUE);
GdkWindow *bin_window;
bin_window = gtk_tree_view_get_bin_window (GTK_TREE_VIEW(tree_view));
gint bin_height;
gdk_drawable_get_size (GDK_DRAWABLE(bin_window), NULL, &bin_height);
gtk_tree_view_set_headers_visible (GTK_TREE_VIEW(tree_view), FALSE);
gint bin_height1;
gdk_drawable_get_size (GDK_DRAWABLE(bin_window), NULL, &bin_height1);
gtk_tree_view_set_headers_visible (GTK_TREE_VIEW(tree_view), TRUE);
return (bin_height - bin_height1);
}
static guint
get_row_height (GtkTreeView *tree_view)
{
guint row_height = 0;
GList *columns = gtk_tree_view_get_columns (tree_view);
GList *current = columns;
while (current) {
GtkTreeViewColumn *renderers =
gtk_tree_view_column_get_cell_renderers
((GtkTreeViewColumn *) current->data);
guint cell_height = 0;
GList *current1 = renderers;
while (current1) {
GtkCellRenderer *renderer = (GtkCellRenderer *)
current1->data;
guint height;
gtk_cell_renderer_get_size (renderer,
GTK_TREE_VIEW(tree_view),
NULL, NULL, NULL, NULL,
&height);
if (height > cell_height)
cell_height = height;
current1 = g_list_next (current1);
}
g_list_free (renderers);
if (cell_height > row_height)
row_height = cell_height;
current = g_list_next (current);
}
g_list_free (columns);
row_height += 4; /* horizontal-separator ? */
return row_height;
}
---
gint grid_height = n_rows * get_row_height (tree_view)
+ get_header_height (tree_view); /* header height ? */
