* QmlProfiler: Rename all the timeline model data structs to ItemUlf Hermann2018-05-111-8/+8
| | | | | | | | This allows us to define a template for filling a QmlProfilerTimelineModel without spelling out all the type names. Change-Id: I97870287a795d95f58a949729afa715f145817bb Reviewed-by: Christian Kandeler <christian.kandeler@qt.io>
* Move Timeline and FlameGraph into a common "Tracing" libraryUlf Hermann2018-05-041-1/+1
| | | | | | | | | | This allows us to share code between the two, in particular the QML code for the Details window, and the theme code. This way we can potentially deduplicate some code.

* Timeline: Move modelId generation into aggregatorUlf Hermann2018-04-171-1/+2
| | | | | | | | | | | The way the notes model works requires every timeline model to have a different ID. Conversely no other kind of model actually needs an ID. Therefore it makes sense to have the TimelineModelAggregator manage the IDs as every timeline model will sooner or later be associated with an aggregator.

* Timeline: Use some better number typesUlf Hermann2018-01-161-1/+1
| | | | | | | | | | | | The scale parameters are converted to single precision float anyway as soon as we do something with them. We might as well change all the methods to be single precision, too. The min/max row values should really be 64bit as 32bit values are not enough to express memory usage.

* Timeline: Use QRgb and a lookup table for colorsUlf Hermann2016-11-091-1/+1
| | | | | | | | | | | | | It makes no sense to return a QColor as the only things we are using are the red, green, and blue components. Furthermore, colorFromHue() can only generate 360 different colors which we can easily cache instead of recalculating them on each request. This significantly reduces the time it takes to update the timeline render nodes. Change-Id: I7961014364a1bec5b089285148b2e6c141a6dc7d Reviewed-by: Christian Kandeler <christian.kandeler@qt.io>

* QmlProfiler: Load the timeline model data event by eventUlf Hermann2016-05-231-195/+183
| | | | | | | | | | | | All the models do the same thing when loading the data: They iterate the list of events, determine for each one if they accept it, and if so, they load it. After the list has been fully loaded, they do some finalization. This can be centralized, and ultimately we won't need to expose the central QVector<QmlEvent> for that anymore.

* QmlProfiler: Remove detailed progress trackingUlf Hermann2016-05-231-4/+0
| | | | | | | | | | The progress bar in the state widget was rather meaningless. We rarely know how many events we expect and it's rather hard to tell how long each model will take to process them. Instead, we just show a 0-ranged progress bar to tell the user that "something is happening". Change-Id: Icb80840d1f0a1538bcf254faa37cbb36e25d342c Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
* QmlProfiler: Add a QmlTypedEvent and extend QmlEventUlf Hermann2016-05-091-5/+5
| | | | | | | | | | | | | | | | The QmlTypedEvent is mainly useful to read a generic QmlEvent and QmlEventType from a QPacket. QmlEventType has a stream operator to do exactly that. QmlEvent also gets further options to store 32-bit data in addition to 64- and 8-bit data. Also, with the more generic storage layout we can reduce the memory consumption of range events by 50%. This comes at the cost of additional memory allocations for non-range events, but as non-range events are significantly less frequent than range events, this is a good tradeoff. Finally the new storage layout lends itself to efficient serialization, which will help when developing new storage and transfer formats for QML traces.
