Starting with Qt 5.6, setting the environment variable QT_SCALE_FACTOR
makes everything accordingly bigger. So, if QT_SCALE_FACTOR=1.2, all
text and GUI elements are rendered 20% bigger. However, if an application
does not account for this, everything will also look "blocky".
With this commit, all text and images will be scaled remaining sharp.
This works whether a HiDpi screen is used or not, but is mostly useful
with a HiDpi screen, as all GUI elements are more spaced apart and one
can use the mouse for selecting things without requiring a high precision.

The root of the issue is in Buffer::reload() called during "Save As". After
loadLyXFile() there, all the insets have been deleted, and therefore the Inset
pointer GuiView::documentBufferView()->cursor().inset() is dangling. Immediately
after loadLyXFile(), reload() calls updateBuffer() which causes a segfault.
While debugging I got other segfaults caused by the same dangling Inset pointer
in Cursor, notably: 1) a trace identical to the second one from
<http://www.lyx.org/trac/ticket/10520>, and 2) a similar segfault in the
critical path after emergency saving (call to inMathed()).
Having to "refresh" by hand the inset pointer cache in CursorSlice is very
unsatisfactory, but there does not appears to be a consistent strategy for
managing these Inset pointers in CursorSlice.
- Allow using logical values for icon sizes as the standard sizes may
differ among different icon sets
- Do not allow setting sizes smaller than smallIconSize
When the logical sizes differ and the icon set is changed, the correct
sizes are established only after a restart.
- Adds LFUNs for setting the icon size
- Adds icons sizes to the Toolbars menu
- Uses the Toolbars menu as application context menu
- The context menu can now be user defined in stdcontext.inc
Fixes ticket #10428.
This should avoid performance problems related to the window update machinery.
Moreover this fixes a crash introduced by 82808fea when closing a file.
Note that GuiWorkArea::Private already had a read_only_ member, but it
was unused.
Also rename LyXVC::vcname() to LyXVC::vcstatus() since it now contains
directly the UI string to be shown.
The limit of 10% is used in both getStatus() and dispatch() to set a
minimum zoom level. Having it centralized makes the code more
readable and makes changing the minimum less error-prone.
The window title is built from the current file name and its
mofidication state. We use our own code instead of the automatic title
bar provided when windowFileName() is set because
1/ Qt does not keep the full path name
2/ Qt does not yield a nice application name
The "read only" and "version control" status are shown in the status bar:
* for read only we use the tab read only emblem (with the right size)
* for version control, we show the name of the backend (using a new
vcname() method of the backend).
The iconText() of the view is not updated anymore, since this is
deprecated in Qt5.
buffer-zoom-out can actually zoom in (by giving a positive number as
the argument), so it should only be disabled at the minimum zoom
level if it is indeed zooming out.
Similarly, buffer-zoom-in can zoom out, so it should be disabled if
the user is at the minimum zoom and it is called to zoom out.
This commit amends 8884c404.
The field prettyname can accept Unicode and therefore must be parsed into a
docstring.
Little simplification of the code on the way.
* For other fields, either a validator should be set to prevent non-ascii input
in the preferences, or they should be transformed into docstring too.
Fix assertion with gcc 6: The comparison function must be a strict weak
orderings and not give x < x.
Fix assertion when a custom exportable document format is given a non-ASCII
name. Use qt_ to be consistent with the rest of the code.
Use Qt's locale-aware comparison for appropriate sorting.
On Linux and Mac OS, this action brings the LyX window into focus.
Such behavior is not allowed by Windows OS so instead the color of
the taskbar entry is changed to indicate that the window has changed
in some way.
The action is hidden in the shortcuts menu because it would make
sense to assign a shortcut to it. The only way to execute shortcut
would be if the LyX window is already activated.
lyx-activate will be used (see next commit) to allow the PDF viewer
to switch to LyX after executing a reverse search.
"Output changes" alters the preamble even in the absence of tracked
changes. Therefore, not being able to notice when it is activated can possibly
yield hard-to-debug compilation failures.
(#8738)
For efficiency, we add a new flag to the buffer indicating when changes are
present. This flag is updated at each buffer update, and also when explicitly
requested via a dispatch result flag.
whose children is also a child of another buffer, then try to close that
one.
The problem is that we do not check properly to make sure that the child
is not a child of some other buffer. Now we do.
