Some lfuns are handled directly in GuiApplication while handling
of menu hiding in fullscreen was done on the level of GuiView.
We'll see if this code movement breaks in different scenarios,
but quick grep suggested that the only other way to guiview
dispatch is through drag&drop when menu isn't involved.
Add a new ForceAll update flag that forces to update metrics and
redraw all buffer views.
The situation in multi windows setting is very fragile and will need
to be adressed properly in the 2.5 cycle.
This patch takes into account the skewness of a character for properly
align a decoration. Unfortunately, the required amount of shift depends
on single chars, so that the recently introduced FontMetrics::italicSlope()
method cannot be used with all characters. A heuristics that produces
satisfactory results is using the italic slope only with characters whose
italic correction (kerning) is zero.
Part of #11491
Using unordered_map instead of map.
Reasons:
1.) The relevant maps contain 166(Keys) and 649(Accents) entries.
This mean that average access with 'map' needs 8 to 10 compares to find the value.
2.) Since we are using at least c++11, the unordered_map is available
2.) increasing the maps (in future) needs not to be considered anymore, because
the access-time will not increase.
When hitting backspace in the first position of a cell in mathed,
if the cell is part of an array, the whole array is dissolved
and the sole cell content pasted in the containing environment.
But if the cell is part of an eqnarray or align math hull type, the
cursor is simply (and unexpectedly) taken out of the whole equation,
which is left unchanged.
This patch makes backspace equivalent to the cursor left key in those
cases, while leaving the behavior unchanged in all other ones.
Fixes#11678
A reference can be directly inserted into mathed but cannot be pasted
because the pasted material is returned in plain text format. This patch
allows getting a string from the cut stack in a suitable format allowing
the math parser to actually create an InsetRef.
Fixes#11539
In Qt 5.15 many deprecation warnings are issued, presumably for
helping the port to Qt 6. They are really a load but can be
shuten up by using -DQT_NO_DEPRECATED_WARNINGS, except for the ones
about MidButton, AdjustToMinimumContentsLength, and DefaultLocaleLongDate.
This change should not affect compilation with Qt 4, as all changes are
backward compatible (only Qt versions prior 4.5 could be affected).
