MainWindow::showTranslationFor() overloads disable the "Pronounce Word"
action, then call ArticleView::showDefinition(). And then immediately
update pronounce availability, Found in Dictionaries list, Back and
Forward buttons. Since ArticleView::showDefinition() loads the requested
page asynchronously, the previous page is still current. Therefore the
"Pronounce Word" action is immediately re-enabled (if the still-current
article has sounds), the other state updates have no effect whatsoever.
Once the new page is loaded, the state is updated again in
MainWindow::pageLoaded() - this time with the desired effect.
So the only effect of the state updates in
MainWindow::showTranslationFor() is to revert the intentional disabling
of the "Pronounce Word" action. Plus waste some CPU time. The
pronunciation-disabling behavior looks better to me and is consistent
with the scan popup's behavior (which immediately hides the
"Pronounce Word" button).

this is a workaround to pass through the restriction.
If GoldenDict's option "Close to system tray" is checked and
GoldenDict's main window is visible when the user logs out, the logout
is canceled in latest stable versions of KDE Plasma and Xfce desktop
environments (probably in other GNU/Linux desktop environments too, but
they weren't tested). The cause of this unintended and pointless logout
cancellation is ignoring the close event.
Close events are accepted by default. main() calls
`app.setQuitOnLastWindowClosed( false );`. Thus, if the close event is
not touched, the main window is hidden as before this change.
GoldenDict's configuration, history and favorites are still committed
and saved in both KDE Plasma and Xfce when logging out first
closes/hides the main window, then quits GoldenDict.
The change is limited to GNU/Linux because @Abs62 pointed out that
closing the main window breaks global hotkeys on Windows. I have
verified that closing the main window does not break global hotkeys on
GNU/Linux with Qt5 or Qt4. No one has volunteered to test whether the
change is needed on macOS, so it is safer not to apply it there.
Closes #1421.
Most callers of these member functions should escape wildcard symbols in
the `text` argument. Yet nothing in the functions' signatures suggested
such escaping. With the added enum WildcardPolicy argument, the callers
are forced to decide whether or not the wildcards should be escaped.
When not-escaped wildcard symbols are placed in the translate box/line,
word completion can occupy the CPU for seconds. So it is safer to err on
the side of escaping than the other way around.
The missed unescaping in ScanPopup::translateInputFinished() was
inconsistent with the main window. It made escaping in the scan popup's
translate box unusable by attempting to translate e.g. "\*" verbatim.
The geometries of many GoldenDict's dialogs and windows are already
stored in config. Dictionaries dialog can make use of extra horizontal
space when there are many groups, extra vertical space - when there are
many dictionaries. A user can now resize this dialog to her liking once.
Each of the 3 removed history addition requests follows a call to
ArticleView::showDefinition() with the same phrase/word as an argument.
Each showDefinition() overload adds its phrase/word argument to history.
These duplicate history additions weren't noticeable because
History::addItem() searches for and removes its argument from items to
avoid duplicate history entries. But the extra function calls, signal
emissions, linear searches and QList manipulation wasted processor time.
Preferences::sanitizeInputPhrase() transforms an input phrase by
removing its whitespace/punctuation prefix and suffix. Translating a
phrase from X11 primary selection or from clipboard, via mouse-over or
from the command line results in such sanitization. This is useful when
a punctuation mark or a space is selected accidentally alongside a word.
This sanitization can be undesirable, however, when an abbreviated word
is selected. For example: "etc.", "e.g.", "i.e.".
This commit implements searching for the input word with the punctuation
suffix preserved as an alternative form of the sanitized word to show
articles for both. For example, when the word "etc." is translated from
the clipboard, both "ETC" and "etc." articles are displayed.
The punctuation suffix is preserved when the word is passed from the
scan popup to the main window and when the translate line text is
refreshed (e.g. when the current group is changed). The suffix is not
stored in history and favorites (doing so would require file format
changes and possibly substantial code changes, this can be implemented
later if need be).
Trim the input phrase once in ArticleNetworkAccessManager::getResource()
instead of verbose trimming in multiple places in
ArticleMaker::makeDefinitionFor().
Closes #1350.
When a Wikipedia article is already cached, this change reduces the
amount of sent and received network data almost tenfold.
Setting up a network disk cache in the same way for dictNetMgr does not
noticeably impact the amount of network traffic. Either this network
access manager sends and receives very little data or the data is never
the same. So dictNetMgr does not need a disk cache.
Use QNetworkDiskCache's default maximum size of 50 MiB as the default
network cache size. This size is large enough to accommodate tens of
huge MediaWiki articles. It is also small enough that the user is
unlikely to run out of disk space because of the cache.
Clear network cache on exit by default because most users probably
don't load the same online articles after restarting GoldenDict. Plus
storing the network cache on disk indefinitely by default would be a new
and unexpected to the users privacy risk.
Nikita Moor came up with the idea and wrote an initial network disk
cache implementation in #1310.

This commit fixes #907, fixes #1097 and fixes #1155
abcabb77fa added a makeScanPopup() call
after applyQtStyleSheet() in MainWindow constructor to apply Qt style
sheets to the scan popup. This call destroys the scan popup created
earlier in the MainWindow constructor and creates a new instance.
Let us remove the first, now redundant invocation of makeScanPopup()
from MainWindow::makeDictionaries() to improve startup performance.
makeDictionaries() is currently called only once, so modifying it is not
a problem. If makeDictionaries() is used elsewhere in the future,
the added assertion will remind to reconstruct the scan popup.
For example, looking up "United States" in my local dictionaries, then
pressing Ctrl++ to increase zoom factor from 1 to 5 takes 4 seconds with
this change and 25 seconds without it. The same scaling takes 6 seconds
with this change and 45 seconds without when I enable English Wikipedia,
which has a particularly large "United States" article.
There is a workaround that speeds up zooming: look up a nonexistent
word, scale to the desired level, then go back to the large articles.
But this is tedious if large articles are open in scan popup or
in case of many tabs in the main window.
