More changes to the SPARQLbrowser.

- Datagrid columns are rebuilt on each query. Each column represents one of the query bindings.
- Cancel query button. This is only active when the query is running.
There are bugs:
- Datagrid columns sort isn’t sorting on the column contents. It’s a long story but basically because I am building the grid columns from scratch I seem to have run into a problem with missing behaviour which the mxml version does not exhibit.
- Sometimes (but annoyingly not always) the graph just sits there twitching away and does not expand to fill the available space. The reason for this is something to do with the canvas area it has to draw on shrinking. The solution is to change the size of the browser window. The problem will immediately go away. No doubt there is a Noddy fix for this.
The world most esoteric Flex application just got better! I have fixed the issue with the datagrid wordwrap and cell height. Just to recap – if the wordwrap was switched on then long text in a grid cell would push the datagrid off the page!!! Do you know how I fixed this? I heard a colleague at work tallking about setting the minHeight property to zero. I was busy at the time but I knew he was trying to fix a datagrid formatting issue so I thought to myself tonight ‘ho hum..lets see what happens if I set minHeight to zero’. Well it works. No idea why. I will have a chat to the developer tomorrow.The other grid sorting bug remains. Still I remain hopeful. There is always a way (sometimes).
Some cosmetic changes. I have moved the ‘cancel query’ button over to the left and taken out the ‘execute’ label.
