2018-10-20EvView: Fix cursor movement when logical and visual line order differsColomban Wendling1-0/+10
Make sure not to move the caret in the wrong direction when restoring the visual line X offset, in case the visual and logical order is slightly different. The algorithm used to move the cursor on the next line and restore the X position across lines works as follows: 1. Move `cursor_offset` to the next line by incrementing it until reaching a line break; 2. Find the Y coordinate corresponding to the new cursor_offset; 3. Find the text closest to the new Y coordinate and the previous X coordinate. 4. Move cursor_offset to the text at this new (X, Y) location. The issue lies in step 3, which can find a position on a different line than expected in case several lines have a nearly the same Y position.

Fix crash on corrupted PDF with no pages. Thanks to Juha Kylmänen from OUSPG who were testing robutness.

2018-03-22Use GtkOverlay to show the loading messageCarlos Garcia Campos1-99/+31
Remove the EvLoadingWindow from libview and move the implementation to the shell using a EvLoadingMessage widget and GtkOverlay. EvView has now a is-loading property that allows the users to implement their own loading notification system. This fixes several realted to the loading window. origin commit: https://git.gnome.org/browse/evince/commit/?h=gnome-3-8&id=035c1cb
2018-03-19Save/restore context when getting colors for a different stateraveit651-0/+7
Getting colors for a state different from the current state of the corresponding widget without saving the context might trigger an invalidation and a redraw. Because this was happening from the draw function this resulted in a redraw loop and constant high CPU usage. This could be triggered by selecting text or searching. https://bugzilla.gnome.org/show_bug.cgi?id=755442 inspired by: https://git.gnome.org/browse/evince/commit/?id=1987f04 https://github.com/linuxmint/xreader/commit/e76a18d

2017-09-06libview: Use a larger damage area to redraw selectionsCarlos Garcia Campos1-27/+25
Depending on the zoom level the area actually drawn by cairo can be a bit larger than the selected region due to rounding errors or pixel alignment. We use the selected region to build the damage area to invalidate when drawing selections which in many cases is not large enough. This causes that sometimes when removing a selections some small rectangles keep drawn because they are not redrawn. To avoid this we grow the damage area computed from selected regions. origin commit: https://git.gnome.org/browse/evince/commit/?h=gnome-3-10&id=a497fb4
