2021-02-17desktop: fold ApplicationState into MainWindowGravatar Berthold Stoeger
The application state is a desktop-only thing. The mobile UI also has its application state, but that is something completely different. The last remaining user of the application state was to flag whether the planner is active. Since this has all been unglobalized, the ApplicationState structure can be moved from core to the desktop UI. And there it can be made local to the MainWindow class.

2021-02-13statistics: implement primitive "restrict to selection" featureGravatar Berthold Stoeger
Allow the user to restrict the analyzed dives based on the current selection. One button restricts to the current selection and one button resets the restriction. Thus, the user can for example select bars in the bar chart or a range in the scatter plot and perform statistics on these sets. The restriction works on top of the filter. The UI can certainly be improved, but it is a start. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-20statistics: don't replot chart when changing featuresGravatar Berthold Stoeger
Up to now, when the user changed the visibility of chart features (legend, quartiles, labels, etc.) the whole chart was replot. Instead, only change the visibility status of these items. After all, this modularity is one of the things the conversion to QSG was all about. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-10statistics: convert chart to QQuickItemGravatar Berthold Stoeger
It turns out that the wrong base class was used for the chart. QQuickWidget can only be used on desktop, not in a mobile UI. Therefore, turn this into a QQuickItem and move the container QQuickWidget into desktop-only code. Currently, this code is insane: The chart is rendered onto a QGraphicsScene (as it was before), which is then rendered into a QImage, which is transformed into a QSGTexture, which is then projected onto the device. This is performed on every mouse move event, since these events in general change the position of the info-box. The plan is to slowly convert elements such as the info-box into QQuickItems. Browsing the QtQuick documentation, this will not be much fun. Also note that the rendering currently tears, flickers and has antialiasing artifacts, most likely owing to integer (QImage) to floating point (QGraphicsScene, QQuickItem) conversion problems. The data flow is QGraphicsScene (float) -> QImage (int) -> QQuickItem (float). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-03statistics: reverse chart selection logicGravatar Berthold Stoeger
The old ways was to select the chart first, then depending on the chart choose the binning. Willem says that it should work the other way round: select the binning (or operation) and make the charts depend on that. I'm not arguing one way or the other, just note that the new way is much more tricky, because it is easy to get unsupported combinations. For example, there is no chart where the first variable is unbinned, but the second axis is binned or has an operation. This makes things distinctly more tricky and this code still needs a thorough audit. Since this is all more tricky, implement a "invalid" chart state. Ideally that should be never shown to the user, but let's try to be defensive. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-03statistics: implement a statistics widget on desktopGravatar Berthold Stoeger
Implement a widget that shows the statistics state as comboboxes and the statistics chart. Calls into the statistics code if any of the comboboxes changes. The hardest part here is the formatting of the charts list with its icons and with headings. Sadly, it is not trivial to arrange icons horizontally. Therefore we would have to fully reimplement the ComboBox view, which is probably not fun. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
