-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi,
I wrote my own 'chart' implementation for date's so it can be used as planboard. http://uva.hobby-site.com/~skinkie/chart.jpg Now this is all very great (Cairo), but it uses libxml2 to store the data, and reads it in as a GList, so as you might understand *this is not very flexible*. I would like to extend the widget to use a database with a specific representation. For example an id,julian,julian thing. Now I wonder what is the best way to implement this. When I look at some basic widgets like combo's they are in essence gtk+gda, so it should be relatively simple. The same data should be made available in a 'grid' so people can look at the data in two different representations. So I would just perform read operations to render the widget and write operations on 'drops' and new 'instances'. ...but I wonder, is anything in the gnome-db widgets 'cached' and is there any way to receive a signal from the database to 'update' a view? (Maybe this is sample_changed?) I want my final application to be used across different computers and I I currently tested with the demo application if something change if I added stuff between instances there was no update in the other. Is this a feature that is available in the bigger databases such as PostgreSQL or isn't any widget implemented so it can receive live updates? (Or poll for updates?)
