[Stefano Verzegnassi]

[lp:~verzegnassi-stefano/+junk/new-pdf-plugin]

240. By Stefano Verzegnassi on 2016-01-10

* Export Poppler::Error to QML
* Added support for protected PDF documents

241. By Stefano Verzegnassi on 2016-02-25

Sync with trunk

242. By Stefano Verzegnassi on 2016-02-26

Sync PDF plugin with latest LOK-plugin changes:
- Pinch to zoom (not tested)
- Double tap to zoom (not tested)
- Use UITK 1.3 ScrollView
- Zoom settings as a separate object
- Use UCUnits for a better scaling strategy/support
- Zoom modes: manual, fit width, fit page and automatic (as gnome-evince)
- Don't remove QImage data in SGTileItem

And probably some other minor change. There's some chance I've introduced some new bug here and there. Anyway that's not yet relevant because of the current status of the plugin.

243. By Stefano Verzegnassi on 2016-02-28

Use uitk units for rendering the document

244. By Stefano Verzegnassi on 2016-04-07

* Changed LinkHint style
* OpenLinkDialog: fixed button text

245. By Stefano Verzegnassi on 2016-04-15

* Fixed an issue with pinch zooming in PDF viewer
* Removed tiled rendering from PdfPageItem
* Create PdfPageItem only for visible indices - stop creating all the pages on initialization
* Fixed VerticalView::positionAtIndex() as consequence of the change above

246. By Stefano Verzegnassi on 2016-04-15

Added rotation support - pt.1

247. By Stefano Verzegnassi on 2016-04-15

Added rotation support - pt.2

248. By Stefano Verzegnassi on 2016-04-15

* Added TODO and FIXME tasks
* Fixed a bug with VerticalView width when rotated

249. By Stefano Verzegnassi on 2016-04-15

* Fixed PDF link support
* Added touch support for links

250. By Stefano Verzegnassi on 2016-04-15

Fixed links rotation

251. By Stefano Verzegnassi on 2016-04-15

disable mouse/touch areas when the flickable is moving + code style

252. By Stefano Verzegnassi on 2016-04-15

Moved all the logic in VerticalView. Removed PdfPageItem class.

253. By Stefano Verzegnassi on 2016-04-15

Forgot to remove a last reference to PdfPageItem

254. By Stefano Verzegnassi on 2016-04-15

Don't show hints on touch gesture

255. By Stefano Verzegnassi on 2016-04-20

Fixed pdf viewer top margin

256. By Stefano Verzegnassi on 2016-04-20

[Fix] GoTo links returning wrong coordinates + typo

257. By Stefano Verzegnassi on 2016-04-20

[Fix] RenderTasks not removed from the queue when the viewport gets cleaned

258. By Stefano Verzegnassi on 2016-04-20

removed obsolete comments

259. By Stefano Verzegnassi on 2016-04-21

Pdf rotation as a separate class

260. By Stefano Verzegnassi on 2016-04-21

* Re-introduced PDF presentation support. Added a QML image provider to the PDF plugin.
* Minor changes to the RenderEngine tasks name.

NB: ImageProvider and paintThumbnail don't work properly yet (i.e. returning an image with a wrong size).

261. By Stefano Verzegnassi on 2016-04-21

TocModel is now filtered by node level, so we don't get a huge list of entries anymore. Also, this now fits with the UI design specifications.

262. By Stefano Verzegnassi on 2016-04-21

Change spacing value according to the current zoom value. Workaround for getting zoom properly working on QML.

263. By Stefano Verzegnassi on 2016-04-22

Fixed broken GoTo dialog

264. By Stefano Verzegnassi on 2016-04-22

Properly use zoomed spacing where required

+    \brief Units of measurement for sizes, spacing, margin, etc.
+
+    Units provides facilities for measuring UI elements in a variety
+    of units other than just pixels.
+
+    A global instance of Units is exposed as the \b{units} context property.
+    Example usage:
+
+    \qml
+    import QtQuick 2.4
+    import Ubuntu.Components 1.2
+
+    Item {
+        width: units.gu(2)

+    }
+    \endqml

+    \sa {Resolution Independence}
+*/
+
+/*
+ * Note on the interaction between GRID_UNIT_PX and QT_DEVICE_PIXEL_RATIO
+ *
+ * In Qt5.4 there is a single means to scale the UI: the QT_DEVICE_PIXEL_RATIO environment
+ * variable. This accepts only integer values, thus allowing a x2 or x3 scaling of any
+ * Qt-based UI, that includes QWidget as well as any QML UI.
+ *
+ * Setting QT_DEVICE_PIXEL_RATIO=2 implies one density-independent pixel corresponds to 2
+ * physical pixels. Developers describe their UI in terms of density-independent pixels.
+ * Qt scales accordingly.
+ *
+ * The Ubuntu UI Toolkit has solved the scaling problem with the GRID_UNIT_PX variable.
+ * It offers more flexibility, but only scales QML applications written to use the UITK
+ * (since it uses this Units class) as it is built on top of QML.
+ *
+ * There are additional areas in Qt where QT_DEVICE_PIXEL_RATIO causes correct scaling which
+ * GRID_UNIT_PX cannot, for example:
+ *   1. cacheBuffer for ListView/GridViews - specified in density-independent pixels
+ *   2. gesture recognition  matches what is on screen better, as it is density-independent
+ *      pixel aware
+ *
+ * In order to get the best of both worlds, Ubuntu will set both GRID_UNIT_PX and
+ * QT_DEVICE_PIXEL_RATIO. Thus all Qt apps will scale reasonably well, with UITK-based apps
+ * scaling perfectly for any desired scale (i.e. non-integer scales).
+ *
+ * However UITK developers can just use this Units class as usual, and will be almost totally
+ * isolated from Qt's own scaling concept.

-/*
- * Some documentation on how this thing works:
- *
- * A flickable has two very important concepts that define the top and
- * height of the flickable area.
- * The top is returned in minYExtent()
- * The height is set using setContentHeight()
- * By changing those two values we can make the list grow up or down
- * as needed. e.g. if we are in the middle of the list
- * and something that is above the viewport grows, since we do not
- * want to change the viewport because of that we just adjust the
- * minYExtent so that the list grows up.
- *
- * The implementation on the list relies on the delegateModel doing
- * most of the instantiation work. You call createItem() when you
- * need to create an item asking for it async or not. If returns null
- * it means the item will be created async and the model will call the
- * itemCreated slot with the item.
- *
- * updatePolish is the central point of dispatch for the work of the
- * class. It is called by the scene graph just before drawing the class.
- * In it we:
- *  * Make sure all items are positioned correctly
- *  * Add/Remove items if needed
- *  * Update the content height if it was dirty
- *
- * m_visibleItems contains all the items we have created at the moment.
- * Actually not all of them are visible since it includes the ones
- * in the cache area we create asynchronously to help performance.
- * The first item in m_visibleItems has the m_firstVisibleIndex in
- * the model. If you actually want to know what is the first
- * item in the viewport you have to find the first non culled element
- * in m_visibleItems
- *
- * The first item of m_visibleItems is the one that defines the
- * positions of all the rest of items (see updatePolish()) and
- * this is why sometimes we move it even if it's not the item
- * that has triggered the function (i.e. in itemGeometryChanged())
- *
- * m_visibleItems is a list of ListItem. Each ListItem
- * will contain a item and potentially a sectionItem. The sectionItem
- * is only there when the list is using sectionDelegate+sectionProperty
- * and this is the first item of the section. Each ListItem is vertically
- * layouted with the sectionItem first and then the item.
- *
- * Note that minYExtent and height are not always totally accurate, since
- * we don't have the items created we can't guess their heights
- * so we can only guarantee the values are correct when the first/last
- * items of the list are visible, otherwise we just live with good enough
- * values that make the list scrollable
- *
- * There are a few things that are not really implemented or tested properly
- * which we don't use at the moment like changing the model, etc.
- * The known missing features are marked with TODOs along the code.
