This allows to make computing the best width of numeric columns an O(1)
operation instead of O(number-of-rows), which can make a huge difference
for big grids.
Previously columns using a set of predetermined values used plain
wxGridCellStringRenderer, which didn't allow to determine their best
size efficiently, as wxGrid had to iterate over all the rows of the
table, even if they only took a couple of possible values.
Add wxGridCellChoiceRenderer (refactoring wxGridCellEnumRenderer to
extract the common code from it in the process) which implements
GetMaxBestSize() by just finding the best size of all of these values,
which is much faster for large grids.
This does result in a change in behaviour, as the column now adapts to
its "theoretical" best size and not just the size of the values actually
shown in it, but this seems to be a worthwhile trade-off and could even
be seen as an advantage, as editing a cell won't make its value overflow
the auto-sized column width any more, as it is wide enough to show any
of the column values.
This is another optimization, useful for the renderers that are used
with the values of a fixed form or part of a limited set, as it is much
faster to compute the best size for all values of the set rather than
computing them for all the cells in the column.
The wxMDIParentFrame::Create() function simply called
wxApp::GetRegisteredClassName(wxT("wxMDIFrame")) without providing
apropriate flags parameter depending on the presence/absence of the
wxFULL_REPAINT_ON_RESIZE flag in style. Thus, the MDI parent frame was
always created using the window class with the CS_HREDRAW | CS_VREDRAW
style flags set. Choosing the appropriate value for the flags parameter
of the wxApp::GetRegisteredClassName() function (like in the
wxWindowMSW::GetMSWClassName() function) fixes the flicker issue. The
wxApp::GetRegisteredClassName() call in wxMDIChildFrame::Create()
is adapted as well just for the sake of consistency.

We need to explicitly call SetInitialSize() after setting the value of
the control (if it's not empty), as the first call, done from inside of
PostCreation(), doesn't take the initial control contents into account
and so doesn't allocate the height correctly for multiline text controls
containing more than 2 lines of text, for example.

Skip correction for the under/overhang for non-italic fonts: it seems to
be pretty small for them and avoiding the calls to ::GetCharABCWidths()
makes GetTextExtent() 7-8 times faster, which seems to be a worthwhile
compensation.
If we decide to restore these calls in the future, we will need to
implement some kind of cache for them, as they're just too slow
otherwise.
Handle the case of a single line string specially, it's faster to do
this than use slow loop over all characters.
Also avoid constructing the string with the characters to measure one by
one and do it all at once instead.
Add a possibility to benchmark GetMultiLineTextExtent() rather than
GetTextExtent() in the graphics benchmark.
There is no need to reimplement the same logic in wxGrid code when we
already have a perfectly cromulent way to do it in wxDC itself (which
hadn't existed when this code was originally written, explaining why it
wasn't used here before).
This makes the code shorter and also a bit faster, as we avoid using
wxStringTokenizer unnecessarily.
No changes in behaviour.
Extend wxAnimationCtrl XRC handler to cover wxGenericAnimationCtrl too.
Also fix a bug with wxGenericAnimationCtrl inactive bitmap background.

Fix and improve DPI handling in wxStyledTextCtrl.
Fix cursor size after DPI change.
Enable handling DPI events in wxSTCPopupWindow and other popup windows
(that do not inherit from wxTopLevelWindow).
Some cleanup of STC example, and add option to select drawing
technology.

This function basically only exists in order to be used in this handler,
so extend it to allow doing it by adding wxAnimationCtrlBase argument to
it, allowing it to create wxAnimation object compatible with the given
control.
This reduces code duplication and, incidentally, makes GetAnimation()
more useful for any user-defined XRC handlers.
It contained a single function which can be defined in xh_animatctrl.cpp
instead as it's only used there anyhow, and this file has no more reason
to exist, as "adv" library itself doesn't exist any longer.
This is consistent with the current behaviour of GetSizeFromTextSize()
and the behaviour of GetBestSize() before the changes in this branch.
This is still not consistent with the behaviour of the other ports, but
this will be addressed later, by replacing the currently hardcoded 5.
Note that calling usedRectForTextContainer: here was apparently wrong in
any case because we were not sure to have already performed a layout and
we should have had a call to ensureLayoutForTextContainer: before it to
make it actually work. However, this made it work "too well" because it
then correctly returned potentially very big sizes for the text controls
containing a lot of text, which is not what we need here, as explained
in the comment added by this commit.
This could easily result in infinite recursion, as it is very natural to
implement DoGetBestSize() in terms of GetSizeFromTextSize() and, in
fact, our own implementation of the generic wxSpinCtrl did exactly this.
Avoid such problems by only calling GetSizeFromTextSize() from
DoGetBestSize(), but not in the other direction.
This shouldn't have any effect on the returned size values.
This reverts the changes of 63bcc669d8 (fixing setting initial value
under osx_cocoa for single line text controls, 2009-10-01) and fixes the
problem which this commit probably tried to fix in a different way,
using the same approach as in 98f5315405 (Don't set initial label in
wxNativeWindow on OS X, 2016-04-29) as the real root of the problem was
that the text set in CreateTextControl() was overwritten later when the
label was set from SetPeer().
This change means that the text is now set correctly before SetPeer()
calls SetInitialSize() call, which makes it possible to set the correct
initial size based on the initial text, as will be done in later
commits.
It also makes Cocoa port more consistent with iOS one, as a nice side
effect.
The correct condition for adding the extra border to the buttons that
would be clipped without it due to the bezel style used for them is to
check that their height is < 20, as SetBezelStyleFromBorderFlags(),
which determines the bezel to use, does, and not if their width is 16,
as this is not the same thing, especially for non-square buttons.
Closes https://github.com/wxWidgets/wxWidgets/pull/1887
After a DPI change, the position of the popup is wrong. It is not shown at the
cursor position anymore.
The correct size and position are calculated by scintilla, and there is no easy
way to access this without modifying scintilla sources.
This way, other windows (like wxPopupWindow) will also be able to handle DPI events.
Override InheritAttributes() and use it to set the initial DPI values.
Adjusting the zoom level does not work correctly. It could lead to ever
increasing zoom.
Instead, set the correct DPI of the underlying device context.
Get rid of the unnecessarily complicated functions doing two quite
different things depending on whether their first boolean parameter was
true of false.
Instead, split their body between AutoSize{Columns,Rows}() (which used
to call them) and DoGetBestSize(), keeping just the part needed in each
case.
This is much simpler and even more efficient, as it avoids a completely
unnecessary call to CalcDimensions() and Refresh() from DoGetBestSize(),
which doesn't change the current size at all and so doesn't need to
refresh anything, but previously did it and not only once, but twice,
because both of SetOrCalc{Column,Row}Sizes() did it.
Remove needless subtraction of row/column label size before adding it
back again, as this seems completely unnecessary.
No real changes, this is just a simplification.
In the case when a listctrl is clicked outside of any item, the item is
visually deselected, and it is logical that a DESELECTED is sent.
For non-virtual lists this would happen, but for virtual lists it would
either happen or not happen depending on implementation (MSW/generic)
and mode (single/multi). From now on the DESELECTED event is always sent.
Use Mac version for the other ports too, instead of the weird hardcoded
numbers introduced back in 40aa1a7e60 (Implement GetSizeFromTextSize()
for wxSpinCtrl., 2012-11-20) which don't make much sense, as they use
vertical text control size to determine the horizontal size of the spin
control.
Do not use the max of spin button height and text control height,
however, as we really want to have the same height as just a normal text
control.
Always return fully initialized wxSize value, even if one of the input
values is unspecified.
Also use TEXTCTRL_BORDER_SIZE to make it slightly more clear what's
going on.
