2016-12-02Qt: Fix QStyledItemDelegate assertions.Gerald Combs1-0/+4
QStyledItemDelegate::paint asserts if you pass it an empty QModelIndex. We were doing this in PercentBarDelegate and TimelineDelegate in order to keep it from drawing any text. Return an empty string from ::displayText instead, which appears to be the correct way to paint without text.

2016-09-02Qt: Add a timeline indicator to conversations.Gerald Combs1-0/+80
Add a timeline indicator to the Start and Duration columns in the Conversations dialog. Add tooltips to the columns that explain what's going on. Round the timeline rect corners and do the same for Prototocol Hierarchy Statistics. This should hopefully differentiate the graph bars from a text selection and IMHO it looks better. Update the PHS and Conversations images in the User's Guide.
