In UniReader:showToc() function we cannot use goto() by page number
but have to use self:gotoTocEntry() because crereader defines its own
CREReader:gotoTocEntry() method which uses "xpointer" field of the TOC
entry for this purpose.
With this fix the TOC navigation in crengine-related files works
correctly, BUT after each jump you have to press Menu to refresh the
page for some reason (adding explicit self:redrawCurrentPage() in the
code before gotoTocEntry() doesn't help). This seems to be an unrelated
problem to do with cr3 caching or something else. I will try to
investigate it as well, but for now I am committing the fix for the TOC side
of the problem.
2. Support deleting highlights from within "show all highlights" function (Shift-N). It is much easier to delete multiple highlights than having to position the cursor on them and press Del.
3. Fix the bug whereby the first press of Menu would overlay the info on top of the book's text.
4. Show the number of bookmarks and highlights in their respective lists.
5. Fix the incorrect section title shown in Menu when the file contains TOC with external links.
6. Rename "start highlight mode" -> "enter highlight mode".
7. Rename "display all highlights" -> "show all highlights".
to the current page display a message "External links unsupported" and
remain in the TOC menu. The reason for this decision is that if the
user chose invalid TOC entry she is more likely to wish to stay in the
TOC menu and choose another entry rather than return to reading immediately.
idea is simple: when starting long operation (page renedering) invert
box on top of screen which has relative width of this page.
This allows easy overview where in document user is, along with
indication that something is still happending.
Perfect use-case are glossy magazines pdfs which have first two
pages in hi-res graphics, so this indicator is very useful to see
that something is still happending and that reader didn't die
1. Finally, removed infomessage about redrawing page in new zoom mode
2. Prevented potentially wrong user's input of non-integer values for page numbers in the 'go to page' input box
3. Removed duplicated code to make screenshot; already included in commands.lua
1. Replace hotkeys Alt+<> & Shift+<> (houpq's request)
2. Restrict maximum X/Y-panning steps by G_width/G_height, respectively.
3. Remove warning out about redrawing in new zoom mode (tigran's request)
1. In order to close issue #59, I've introduced user-configurable values for panning steps - for X- & Y-axis, separately. Now panning is called by pressing fiveway without mod_keys. When one presses Shift+FW, he/she changes panning steps in the following way - Shift-Left/Right = decrease / increase X-panning step (divide or multiply on factor 2), Shift-Up/Down = increase / decrease Y-panning step. The lowest value for panning steps is set 1. Both parameters, shift_x & shift_y, are saved to local settings (i.e. history file).
2. Manual zoom step was also made user-configurable. So, instead of two old zooming functions (with fixed 10% and 20%-steps), I made one function to zoom (Shift+<>), while the other (Alt+<>) changes the zoom step downto minimum 1%.
3. Fresh introduced function to change parameter rcountmax was added by storing rcountmax to both setting files - global settings & local ones (i.e. history file) - so that the rcountmax-priority (from low to high) is the following: default rcountmax=5 < its value in global settings < rcountmax stored for each concrete document.
3. Dirty, the extention-based hack to avoid reading not crengine-related parameters stored in history files. TODO: one has to finally introduce loadSpecialSettings() & readSpecialSettings() for PDFReader & DJVUReader and to store therein the reader-specific parameters (like globalgamma, bbox, globalzoom, globalzoom_mode; render_mode = for djvu-files only, etc.)
4. Some lua-code cosmetics (to make code more readable); for example: "self.pan_margin = settings:readSetting("pan_margin") or self.pan_margin" instead of
"local pan_margin = settings:readSetting("pan_margin")
if pan_margin then
self.pan_margin = pan_margin
end"
5. Fix for the today's tigran123 fix: issue #246 (details are included). Added InfoMessage:show() to inform most impatient users that the reader tries to redraw new zoo mode.
6. The fontface for the reading info (called by 'Menu') is restored to be in accordance with original intentions and with the same fontface in crereader.lua - namely, Font:getFace("rifont", 20)
7. Moved the exit hotkeys (Alt+Back & Home) to the end of hotkey list.
otherwise it gives an impression that the program hangs (unless the user presses Next page or does anything else that causes
screen refresh, e.g. manual screen refresh).
1. Restored default value rcountmax=5; the function to make manual full screen refresh is no more silent; at first, it asks user to set a number of partial refreshes (rcountmax) and then performs full refresh. TODO: saving parameter 'rcountmax' in the global reader settings (or separately, for each document).
2. The hotkey 'R' and the respective function toggle_render_mode() for djvu-documents are moved to djvureader.
3. Added hotkey 'M' and the respective function that calls menu with zoom-modes. Probably, one needs to remove unappropriate items, like "Fit zoom to page" and, less probably, the hotkeys (A, S, D, F and ^A, ^S, ^D, ^F) to set zoom-mode directly.
Also added support for all other rendering modes handled by djvulibre.
Also made the message print a human-readable description of the mode rather than just the number.
