Avoid setting state to DragSelectingState unless dragging items in
wxTreeCtrl is explicitly allowed, as this this causes bad behaviour
downstream with subsequent selections when the client does anything in
the event handler beyond simply not allowing the event.
Basically, we can't be guaranteed of the mouse state on return from the
event handler, so dropping into drag selection mode is potentially
inappropriate (or just plain bad).
Closes https://github.com/wxWidgets/wxWidgets/pull/1523
In wx API, calling wxTreeCtrl::SelectItem() is supposed to generate an
event.
Also use Qt selection model to support single-selection mode.

These events use a different convention from all the other ones in Qt
and need to be ignored, rather than accepted, to prevent the default
action from occurring.
And these events are also sent to disabled windows, which are never
supposed to receive them in wx API.
Closes https://github.com/wxWidgets/wxWidgets/pull/1371
Let the wx layer handle default-ness, as the auto behaviour has unhappy
consequences that can't be controlled via the wx API. (For example, a
Delete button being considered default simply because it's the first
button in the dialog.)
Closes https://github.com/wxWidgets/wxWidgets/pull/1366
This was previously done only under Mac, but it doesn't seem to make
much sense to skip the mouse event if we handled it by capturing the
mouse and it seems to create problems in wxQt too, so just generalize
the Mac behaviour to all platforms.
See https://github.com/wxWidgets/wxWidgets/pull/1360
Qt notebook page changed events had the wrong "previous page" index in
circumstances where the page has been changed by methods other than
clicking on the tabs, for example using the "Pages->Next page" menu
option in the notebook sample.
Closes https://github.com/wxWidgets/wxWidgets/pull/1359
Using "move" is correct for positioning, as it takes into account the
frame extent. Unfortunately, there is no corresponding API to set the
frame size. So we need to compute the effective client size and use
"resize". We can't use "setGeometry" for this purpose, since a widget's
"geometry" excludes the frame size. We would need to adjust the position
to go from frame to client coordinates. It's more straightforward to
simply have Qt do it with "move".
Closes https://github.com/wxWidgets/wxWidgets/pull/1349
Handle some mouse events explicitly when a wxQtScrollArea is set as
"mouse captured".
The issue arises in that the QScrollArea has two methods: event() and
viewportEvent(). Normally a "QAbstractScrollAreaFilter" is set up by Qt
which routes any events to the viewportEvent() method. And the normal
event() method throws mouse events away (for reasons I'm not aware of -
but it is what it is). If a wx window with a scroll area (e.g.
wxRichTextCtrl) sets capture, the wxQtScrollArea (QScroll-derived) gets
set as the direct "mouse grabber", and all events then bypass the filter
and are sent directly to the "event" method, which throws them away. The
typical result is that the window setting capture no longer gets mouse
events, it keeps capture since it's looking for a mouse up that never
comes, and the app more or less locks up since all mouse events are
being effectively discarded.
This change catches any event that comes in via the event() method and,
when the mouse is captured by the widget, forwards it on to the
viewportEvent method instead, performing what the filter would do via
the normal event routing.
It doesn't forward on "mouse press" events because the initial event
that causes the capture ends up being fed back again, resulting in a
"captured twice" error. The underlying reason I can see for this "being
fed back again" is that, for some inexplicable reason, the
wxRichTextCtrl "skips" the event even though it has actually processed
it and taken capture. That means this solution isn't 100%, but it does
fix the 99%+ cases where the capture is only gotten to redirect mouse
moves and button ups.
Perhaps an alternative solution might be to stop grabbing the mouse in
wxQtScrollArea, but this would require more changes.

Under wxGTK+2, when wxBitmap has a wxMask but this mask shouldn't be used
in the actual drawing (useMask parameter in wxDC::DrawBitmap() is set to
false), we need to get bitmap data from the buffer with raw (original,
non-masked) data and not from the buffer containing data with mask applied.
Close#18498.
Under wxGTK+2 bitmap data with mask and without it (raw) should be stored
in the separate GdkPixbuf buffers - just like it's done in wxGTK+3. These
two buffers are necessary because only GdkPixbuf with raw bitmap data
(original, non-masked) should be copied when wxBitmapRefData instance is
cloned e.g. in SetMask(). GdkPixbuf with masked data is not copied and is
created on first use in wxBitmap::GetPixbuf().
Closes#18508.
See #18498.
The initial value was not taken into account before because the best
size computed before it was set, i.e. for the empty control, was always
used, as it was never invalidated.
Do invalidate it now if the control is created with non-empty value, in
order to adjust its best, and initial, size appropriately to its
contents.
Closes#18507.

Use wxHeaderCtrl-specific GetColumnTitleWidth() function to account for
the native header control margins, otherwise the computed width could be
insufficient for short columns, resulting in their ellipsization.
Follow Wine in using 3*SM_CXEDGE as margins on each side.
This also has the advantage of working better in high DPI, as we don't
hardcode the value in pixels any longer.
Add wxGrid::DisableHidingColumns() method which can be used to prevent
wxHeaderCtrl from allowing the user to hide columns interactively, which
is something it allows to do by default, unlike the "built-in" wxGrid
header.
Also add EnableHidingColumns() and CanHideColumns() for consistency with
the other similar methods.
Closes https://github.com/wxWidgets/wxWidgets/pull/1554
wxOSX asserts if a menu item with id of 0 is created, so use 1-based IDs
to avoid this.
Using an explicit constant for the base instead of using 0 implicitly
also arguably makes the code more clear.
Closes https://github.com/wxWidgets/wxWidgets/pull/1555
For bitmap with both alpha channel and mask we have to apply mask on our own because 32 bpp icons don't work properly with mask bitmaps. To do so we will create a temporary bitmap with copy of RGB data and with alpha channel being a superposition of the original alpha values and the mask.
See #18498.
For 32 bpp wxBitmap with both alpha channel and mask we have to apply mask on our own while drawing the bitmap because MaskBlt() API doesn't work properly with 32 bpp RGBA bitmaps. To do so we need to create a temporary bitmap with copy of original RGB data and with alpha channel being a superposition of the original alpha values and the mask.
See #18498.
Avoid touching the model while updating the control due to the items
being deleted from it, as doing this can easily result in dereferencing
pointers to the already deleted objects and crashing.
This is rather ugly, but the original code seems to have been written
with this approach in mind (see preexisting comments in ItemDeleted())
and, to be fair, there doesn't seem any other solution with the existing
API, as it allows (or maybe even requires?) deleting the items _before_
notifying the control about their removal and so not giving it any
opportunity to stop editing the item while it's still alive.
Closes#18337.
Having 2 different overloads might have been useful for Carbon
implementation, but as they do exactly the same thing in the Cocoa
version, leave only one of them -- and don't pass it the item, or items,
being deleted as they're not used anyhow.
No real changes.
Pressing Backspace in controls with custom autocompleter previously
didn't do anything at all, as it didn't work correctly after backspacing
over the just inserted autocompletion, but this was clearly wrong, as it
didn't update the list of available completions even after erasing some
non-autocompleted characters.
Fix this by handling Backspace as any other key and just avoiding
refreshing the control contents needlessly if the completion prefix
didn't change.
Closes#18503.
Building on windowFlags() meant that we inherited a bunch of default
flags that were not affected by Qt::CustomizeWindowHint because we
explicitly specified them when calling setWindowFlags().
Instead of doing this, start with nothing and just add the styles that
we need.
This notably ensures that the frames created without wxCLOSE_BOX style
actually don't have any close button.
Closes https://github.com/wxWidgets/wxWidgets/pull/1335
This notably allows to support wxLC_VIRTUAL style.
Also implement support for checkboxes, improve in-place editing and
implement many other methods and missing functionality (e.g. send the
expected events now).
