Are you using GTK+ 3 ?
Still on GTK+ 2.0.
If so, use GtkGrid instead... possibly just that will fix things for you.
Short of that, if I understand correctly, you have a target state/configuration
of a GtkTable (or GtkGrid), if you construct the table in the target
configuration
from scratch, I take it things work as you want... but dont work properly
after performing some kind of a transformation to reach your target
state...
That's about it.
... perhaps it's worth trying an extra call to gtk_widget_queue_resize()
after modifying your table.
I'm trying that. I have signals connected thus;
g_signal_connect(G_OBJECT(p->canvas), "expose-event",
G_CALLBACK(&plot_expose_event), p);
g_signal_connect(G_OBJECT(p->canvas), "select-item",
G_CALLBACK(&plot_select_event), p);
and get the plot_select_event() routine to calculate and set new canvas
sizes with
gtk_plot_canvas_set_size(GTK_PLOT_CANVAS(p->canvas), width, height);
then call gtk_widget_queue_resize(GTK_WIDGET(p->table));
This causes plot_expose_event() to get called, which calls
gtk_plot_canvas_paint(GTK_PLOT_CANVAS(canvas));
But the table rows seem to expand to the largest canvas and don't seem
to take on variable heights.
Feel I've been around and around the mulberry bush on this ;-)

James.

Hi,
I have an application with a tabbed view. On two tabs I have a table, one
is a 2x2 table, the other a 3x1 table (3 rows).
In each cell is a canvas that has a gtk plot.
I want to be able to click one of the plots in the 3x1 table and change the
canvas size to 2/3 the original, with the other two canvases being 1/6 the
original size.
After redrawing and resizing and mucking about, I can't get the table rows
to be different sizes, accommodating the different sized canvases properly,
even though I have gtk_table_set_homogeneous (table, FALSE);
Any clues how to do this?
Regards,
James.
