Otherwise QWebEngineView first creates its underlying view with very
small size which then gets resized to correct size on first show event.
Also remove all calls to setUpdatesEnabled on window during session restore,
it doesn't seem to have any effect anymore.
Queries are now always executed on correct database instance.
Databases are also stored in thread local storage instead of in hash
table with mutex.
Closes#2498
Web page is now correctly focused when opening browser window
or opening/restoring sessions.
This is still not absolutely reliable solution as it uses delay
to change focus to webview, because QWebEngineView doesn't accept
focus until after it is initialized.
Pinned tabs are saved alongside normal tabs in a session file.
If user don't have session restore enabled, pinned tabs are saved
and restored from a special pinnedtabs.dat file which uses different
codepath.
It has also another problem that it only saves pinned tabs for last
browser window, which sometimes may be confusing and lead to losing
the pinned tabs.
* Add initial printing support with QtWebEngine >= 5.7.0
This works by printing to PDF first, then sending the PDF to a printer
if printing to a physical printer was requested.
On *nix (including Mac OS X), we use the lpr command, which is typically
provided by CUPS nowadays. Currently, no options beyond the printer name
are passed, there is room for improvement there. (Okular has a
FilePrinter class that handles this in a more sophisticated way.)
On Windows, we use ShellExecuteW with the "printto" verb. In that case,
the printer name is unfortunately the only thing that can be passed. The
user experience may also be suboptimal depending on the PDF viewer
installed on the system. (E.g., Adobe Reader is reported to ignore
SW_HIDE.) And if there is no PDF viewer installed at all, it will of
course not work at all. But it is the best we can do without bundling
something like GhostScript (or requiring the user to install it).
* Printing: Let lpr autoremove the temporary file instead of QTemporaryFile
Only lpr knows for sure when it is safe to delete the temporary file.
* Printing: Use the callback version of printToPdf instead of the file one
The file version is also asynchronous and does not report when it is
done.
* Printing: Use async QProcess API instead of QProcess::execute to run lpr
This also required making tempFile a QTemporaryFile * instead of a
QTemporaryFile on the stack, because QTemporaryFile is a QObject and
cannot be copied.
* Printing: Adapt the FilePrinter from Okular to pass correct lpr args
The license of those files is GPLv2+, which is compatible with
QupZilla's GPLv3+ licensing.
* ensured the window geometry is remembered on OS X
It was always starting based on:
int windowWidth = desktop->availableGeometry().width() / 1.3;
int windowHeight = desktop->availableGeometry().height() / 1.3;
because quitApp isn’t called on OS X.
* ensured the window geometry is remembered on OS X (v2)
* tweaked coding style
Instead of custom handling of shift + mouse click, use
QWebEngineView::createWindow. It should fix the issue with
JavaScript catching the mouse click performing some action
and QupZilla trying to open new window.
Closes#1898
