The purpose of this custom widget is to allow the use of a QToolBox in a limited
area. The stock QToolBox does not provide a minimum size hint that depends on
the size of the pages; it assumes that there is enough room. This subclass sets
the minimal size of the QToolbox. Without this, the size of the QToolbox is only
determined by values in the ui file and therefore causes portability and
localisation issues. Note that the computation of the minimum size hint depends
on the minimum size hints of the page widgets. Therefore page widgets must have
a layout with layoutSizeContraint = SetMinimumSize or similar.
Ask the user for removing bindings when using the "restore" button (#9174).
Fix the already-bound-key detection logic.
Don't forget to trigger the search when initializing the search LineEdit with
its former value.
With Qt 5, our code did not correctly detect when icons were
available and thus tried to use nonexistent icons.
QIcon::hasThemeIcon(theme_icon) returns true when theme_icon is
empty. We now rely on the behavior that QIcon::isNull() returns true
if the icon is empty.
The same code is used with Qt 4 and Qt 5.
This is used when scaling graphics previews. It is also used on a rare occasion
to scale instant previews when the user's configuration mixes low-dpi and
high-dpi monitors (#10114).
2.1.x allows some document settings to have negative values where
2.2.0rc1 does not (because of the bug fix at 9e166088). If a user of
2.2.0rc1 opens a document from 2.1.x that contains one such negative
value, it will appear as though no change to the document settings
can be saved because 2.2.0rc1 treats the document settings as
invalid immediately on opening the dialog. Further, unless the user
manually goes through each tab they will not see the red text next
to the input that is now considered invalid. This could lead to
confusion for users. One example of such confusion is [1].
The following settings now allow negative values, which is
consistent with 2.1.x. Negative values in these settings do not lead
to LaTeX errors:
- Text Layout tab: the two line edits enabled with "Custom"
- Page Margins tab: all eight line edits
The following settings are not changed by this commit, so they now
(with 2.2.0) do not allow negative values that 2.1.x allowed. This
change makes sense because negative values lead to LaTeX errors in
these cases:
- Page Layout tab: the "Height" and "Width" line edits, which are
enabled when "Custom" is selected

An undocumented behaviour of QClipboard::mimeData() is that it can fail on
windows due to the specificities of the windows API that allow a race condition.
In particular it seems that querying the clipboard as soon as the dataChanged()
signal is received favourises this race condition.
Thanks to Trac user bquistorff for the explanation and a proof of concept patch.

These wms have trouble with the fix at b5a2f1c7, probably more precisely with
the trick to force the calculation of the actual sizes before the display
(layout->invalidate() and the code around it).
This patch gets rid of the code that forces the calculation. As a consequence,
the minimum sizes are again incorrect the first time the window is shown. They
are only correct the second time the window is shown. Now here is the trick: LyX
remembers the sizes of windows between sessions. Therefore, as soon as the good
minimum size has been set, the good size is remembered for the next
session. Thus, in the following sessions, even though the minimum size is
incorrect the first time, the dialog still opens with the good size. So the user
does not see the problem in practice, apart from the very first time.
This is meant as a temporary workaround.
* provide GuiApplication::typewriterSystemFont() to get a fixed font consistently
* enlarge fixed font on Mac because of the too small default Qt system font
* use it in source pane, progress view, log view and document preamble editor
7b1107d7 introduced the following inconveniences which are regressions to 2.1:
* The citation dialog can open with vertical scroll bars in the options
* The citation dialog can open with horizontal scroll bars, especially if the
translated text is longer than the original text (e.g. in FR)
* Resizing the dialog is inconvenient because it increases the gap between the
options. This is unlike before when the dialog could let us see more of the
reference list when enlarging.
This is because the QToolbox that the above commit introduced is not natively
aware of the sizes of its page sub-widgets. The widget is not conceived for this
use, where the space is scarce.
Geometry values provided in the ui file (automatically computed by qtcreator I
suppose) somehow gave the illusion that it worked, but relying on such values is
not portable : it does not take into account the specific theme, font sizes and
localization. This explains why it failed on my side and will probably fail in
other settings too.
Luckily, there is a simple way to make QToolbox suitable for the current use,
which is to add the "missing link" which computes its size based on the minimal
sizes of its pages. The result looks very nice and intuitive. It solves all the
aforementioned issues.
According to callgrind, the time taken to display the symbol dialog is spent in
updateSymbolsList. No longer translate strings for every symbol. This speeds
it up more or less by a factor two.
The stmary font has an unusual large descent that was causing a large
gap between lines in the math delimiter dialog because of the \llbracket
and \rrbracket delimiters. The solution is to force Qt using the same
size for all elements of the QlistWidget widget instead of letting it
compute the size of each element.
* breakRow: remove wrong condition that would silently eat the contents of the
paragraph when the window is narrower than left margin
* breakRow: make sure that there is at least one element in each row
* breakAt: when force-breaking a row element, make sure it is not empty. Doing
so may create empty rows and therefore a endless loop.
Fixes bugs #9962 and #10001.
removeShortcut() restores default settings, therefore was used incorrectly. I
introduce deactivateShortcuts() which only removes assignments.
Clean up a bit the lack of view / model distinction (getting rid of the crashing
code at the same time).
Repair inconsistency of the selection in the "modify" case. (regression at
717d19d3c)
Make the test for existing bindings a bit more robust. (Not perfect yet.)
Focus on the item that has just been added/modified. (cosmetic)
When an inset is separated from the adjacent string by a space, it is
reasonable to be able to break the string after the space.
Unfortunately, QTextLayout does not do that.
This patch reverts the workaround inserted in 71378268 and replaces it
with a different trick: the string is enlosed between a pair of
zero-width non breaking space characters, so that the leading/trailing
spaces are now normal spaces, where QTextLayout will agree to break
the string.
Fixes bug #9921 for good.
* Increase LyX format
* New function convert_info_insets in lyx2lyx_tools.py
Use this function in the future for future updates of info insets
* Convert "inset-modify tabular" to "tabular-feature" in info insets
* Remove icon naming hack regarding "inset-modify tabular"
The tabular-features LFUN was merged with "inset-modify tabular" when
simplifying the tabular dialog at b5049e7. This choice later indirectly caused a
few regressions (#7308, #9794).
I reintroduce tabular-feature to allow more flexibility for user
commands, whereas "inset-modify tabular" is now reserved for the tabular
dialog. In particular, inset-modify tabular is no longer caught by math grid
insets. The name tabular-feature is kept to avoid renaming icons.
Known issues:
* After successfully applying a tabular command, the cursor is truncated to the
table.
* Note that the tabular dialog still has similar issues that are inherited from
the achitecture of the dialog menu. For instance the pref change can be
mis-dispatched to an inset inside a cell and cause an error, for instance:
Lexer.cpp (934): Missing 'Note'-tag in InsetNote::string2params. Got
tabular instead. Line: 0
Maybe the inset-modify LFUN should be modified to treat commands coming from
the wrong dialog (by checking the type) as unknown and undispatched so that
the parent can get it. In that case a non AtPoint variant of inset-modify
could be reintroduced in order to generalise tabular-feature. See:
http://mid.gmane.org/n4rdk1$efj$1@ger.gmane.org
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.
At d449e7e6 it has been decided that submenus are going to be displayed even if
all their items are disabled. Here we make an exception for OptSubmenus.
Example of submenu no longer shown: Insert > Insert Regexp
Example of submenu always shown: Edit > Math > Limit Type, Macro Definition
After d5a5fbb8, as indicated in the commit log, it remained to make sure that
the sub-menus of the navigation menu showing the TOCs are generated in a delayed
fashion, to avoid corner cases regarding performance when documents have very
lengthy tocs (e.g. in a document with 1000 sections it takes a few hundreds
milliseconds for the menu to be refreshed). But this idea actually requires
substantial changes to the way menus are computed, so it is not for now.
In the meanwhile, I reintroduce a max size for menus, after which it is cut
off. This differs from the one that I removed at d5a5fbb8 in two ways: 1) if
there are more items than the max size, then we still show something instead of
nothing, 2) we allow ourselves to rely on qt's scrollable menus and therefore
allow bigger menus than before the above commit. The philosophy is that it is
better to show something than nothing, that it's better to show a scrollable
menu than to cut the menu to fit the screen, and that beyond a certain size the
scrollable menu becomes useless anyways.
