08209c039f Correctly limit overview transaction list (John Moffett)
Pull request description:
Fixes#703
The way the main overview page limits the number of transactions displayed (currently 5) is not an appropriate use of Qt. Our subclassed transaction sort/filter proxy model returns a maximum of `5` in `rowCount()`. However, the model itself actually may hold significantly more. While this has _worked_, it breaks the contract of `rowCount()`.
If `bitcoin-qt` is run with a DEBUG build of Qt, it'll result in an assert-crash in certain relatively common situations (see #703 for details). Instead of artificially limiting the `rowCount()` in the subclassed filter, we can hide/unhide the rows in the displaying `QListView` upon any changes in the sorted proxy filter.
I loaded a wallet with 20,000 transactions and did not notice any performance differences between master and this branch.
For reference, this is the list I'm referring to:
