Because Compare uses threads, we need to make sure it is finished when a
compare is executed from the command line. This was a problem for command
sequences, because the next command would start running before the compare
was done, and the buffer with differences was available.
So this commit adds the "run-blocking" parameter when using
LFUN_DIALOG_SHOW to run a Compare. When calling Compare with run-sync, the
LFUN will wait for the compare worker thread to finish before returning and
possibly running the next command.
To do this, hard-coded test for xcb had to be replaced with a call to
platformName(). Since this method does not exist in Qt4, we emulate
it.
Note that Qt5 uses xcb bindings for X11 system, while Qt4 relies on
older X11 bindings. We return platorm == "qt4x11" in this case.
Fixes bug #11746.
The option here is to NOT indent the paragraph, so make that clear.
As it was, we would set "Indent" to false in the case of paragraphs
that do not permit indentation and then write that, uselessly, to the
LyX file if we wrote any other option (and then keep writing it, even
if other options were removed). Now, we will write it only if it's been
explicitly set.
The method horizontalAdvance() replaces width() starting with Qt 5.11.
To handle this, all direct calls to QFontMetrics::width() are replaced
by calls to GuiFontMetrics::width(), and the code for
GuiFontMetrics::width(QChar) uses horizontalAdvance on newer Qt
versions.
Without this patch, there would be errors like these (warnings turned into errors):
D:\LyX\lyx-unstable\src\frontends\qt\GuiView.cpp(2413): error C4101: 'e': unreferenced local variable
D:\LyX\lyx-unstable\src\frontends\qt\GuiView.cpp(4879): error C4101: 'ex': unreferenced local variable
Intended changes:
* code is shorter and cleaner
* caret scales better with zoom when cursor_width=0: completion
indicator, l-shaped cursor...
Details:
* Rename BufferView::getPosAndHeight to getPosAndDim because ascent is
needed too and width could in the future be set depending on font.
* Get rid of rect_ in CaretWidget and record a Dimension (and y value) instead.
Remove also caret_width_ and slant_, replace rtl_ with dir.
* Make CaretWidget members public and lose the trailing _.
* change CaretWidget::update to read its parameters from current bufferview.
This can lead to mistakes. If no buffer is required at the beginning,
it is better to pass 'nullptr' explicitly.
Fix a case of missing parameter in GuiCompleter (introduced at
f3656600). This avoids some spurious "There is no group open (creating
one)" messages.
