Instead of checking for all text-like controls one by one in
wxCommandEvent::GetString(), call a virtual function checking for this.
This is simpler, less error-prone and faster -- at the cost of
increasing the vtbl size of all wxWindow-derived classes.
Closes https://github.com/wxWidgets/wxWidgets/pull/1696
wxEVT_TEXT events generated by native wxSearchCtrl implementations
always returned an empty string, as wxSearchCtrl was not recognized by
the special hack inside wxCommandEvent::GetString() which retrieved the
text on demand.
Fix this by adding yet another special case for this. This is not ideal,
but should do for now.

Add preliminary support for per-monitor DPI awareness to wxMSW.
Individual controls still need to be fixed, so this support is still
experimental/unfinished for now.

It causes a warning with MSVC code analysis:
"warning C26437: Do not slice (es.63)"
It's unclear if this function even needs to exist, but at least
move it out of line so the warning does not occur for user code.
Remove WXDLLIMPEXP_BASE from wxObjectEventFunctor declaration: this
class only has inline methods and so doesn't define any functions that
would need to be exported from the DLL.
This reverts commit c0f2f38011.
Linking specific applications (sockets/baseserver, base test) resulted in the
following error: undefined reference to `__imp__ZTV20wxObjectEventFunctor'
Fix this by implementing the destructor inside the base library.
No real changes, just clean up sources by removing trailing spaces from
all the non-generated files.
This should hopefully avoid future commits mixing significant changes
with insignificant whitespace ones.
If wxApp::OnExceptionInMainLoop() returns false, we're supposed to exit
the application by stopping its main event loop, not the loop that is
currently running, so do the former instead of the latter.
Also call wxAbort() if we can't exit the application in any other way,
this is not ideal, but still better than not doing anything and, for
example, keeping showing the same "Unexpected error occurred" message
box to the user over and over again if the exception comes from an event
handler being called repeatedly, such as wxEVT_PAINT or wxEVT_IDLE.
This is never going to work, so complain about trying to do it to help with
catching this bug.
This is possible thanks to the new OnDynamicBind() method invoked whenever a
dynamic event handler is bound to a control, so this doesn't detect all
possible occurrences of the bug (such as specifying the handler in a static
event table or in a validator), but it's still better than nothing.
In the future OnDynamicBind() should be extended for other invalid calls, e.g.
binding a handler for wxEVT_TEXT_ENTER to a non-text control shouldn't work
neither, ideally.
Since the changes of 99d9a81e28 a crash would
happen if an event handler was unbound from an object which was later deleted
from its own event handler. As unlikely as such scenario sounds, this is what
happened with wxTaskBarIcon when two wxNotificationMessages were created in
close succession under MSW and it was difficult to debug because of the timing
constraints involved, so avoid similar crashes in the future by avoiding to
use the fields of the object after an event has been handled and postpone
pruning of the unbound event table entries until later time.
See #17229.
Calling Unbind() on another handler from the currently executing handler which
had been bound after (and hence executed before) the handler being unbound
resulted in a crash previously as the iterators used in the loop over all
dynamic event handlers became invalid.
Fix this by storing the dynamic event table entries in a vector instead of a
list (which is also more memory and speed efficient anyhow) and null the
deleted entries instead of removing them to avoid invalidating the iterators
and only really remove them once we finish iterating.
Closes#17229.
Handlers for this event expect to get wxSpinEvent but wxMSW, wxGTK1 and wxQT
sent an object of base wxCommandEvent class which resulted in invalid memory
access in the handlers when using the derived class methods such as Veto().
Closes#16948.
Neither m_isCommandEvent nor, worse, m_propagationLevel was set correctly for
wxCommandEvent objects constructed using copy ctor -- and hence Clone(). This
means that such events were not propagated upwards the window hierarchy, quite
possibly resulting in mysterious bugs.
Fix this now by initializing these fields in both the normal and copy ctors.

These methods can be used to ensure that the exceptions thrown from event
handlers are safely rethrown from the code dispatching the events once the
control flow gets back there.
This allows to work around the problem with not being able to propagate
exceptions through non-C++ code and can be used, for example, to catch
exceptions thrown by the handlers invoked from inside wxYield() by a try/catch
block around wxYield() -- something that didn't work before, update the except
sample to show that it does work now.

If an unhandled exception occurs in an event handler called from Yield(),
don't exit the current event loop which can continue running after handling
this exception in the code calling Yield().

wxCommandEvent::GetString() could return empty string for the
programmatically-generated wxEVT_TEXT events from a wxComboBox.
Fix this by extending the on-demand string retrieval in wxCommandEvent to
wxComboBox as well (it was done only for wxTextCtrl).
Also add a unit test checking that the string has the expected value in the
events sent by all wxTextEntry-derived controls.
Closes#3901.

Contrary to the documentation, wxEventBlocker always behaved as if the
event type to block was wxEVT_ANY: while it returned false for events
not on the blacklist, it never actually called the existing event
handler as it was meant to.
Fix by calling wxEvtHandler::ProcessEvent() in this case.

This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.

Record the object propagating the given event upwards in the event object
itself and use it in wxMDIParentFrame to determine whether the event being
handled is already coming from wxMDIChildFrame and avoid sending it back for
processing it there again in this case.
This is ugly and makes wx event processing even more complex but this is the
only way I could find to ensure that
(a) Both the child and the parent frames get the events from the toolbar
(even though the toolbar parent is the parent frame and hence normally
the child wouldn't get notified about them at all and so the forwarding
at wxMDIParentFrame level is required to make this work).
(b) The child gets the event only once, whether it comes from a toolbar (and
hence indirectly via the parent frame) or from the child menu (and hence
directly to the child, at least in wxMSW).
This commit fixes the event propagation unit test case, at least under MSW and
GTK.

This is similar to the existing GetLinesPerAction() but is for, surprise,
columns.
Also change the documentation to say that the value returned by both of these
methods is 3 under "most platforms" as some wxOSX currently uses 1 and not 3.

Pass the menu event to the window associated with the menu first, before
falling back on wxApp.
This required adding yet another flag to keep state in wxEvent but it seems to
be unavoidable as wxMenuBase::SendEvent() calls ProcessEvent() twice and we
must have some way to distinguish the first call from the second one.
Added a test case verifying that the menu events are indeed processed in the
expected order.

Use the same short names as are used by the event table macros for the event
type constants themselves. This makes them much more comfortable to use, e.g.
Bind(wxEVT_BUTTON) compared to Bind(wxEVT_COMMAND_BUTTON_CLICKED).
The old long names are still kept for backwards compatibility and shouldn't be
removed as it doesn't really cost anything to continue providing them, but all
new event types should only use the short versions.

This results in a noticeable delay when using wxGTK via a remote X11
connection for every key event as a round trip to server is needed to get the
mouse pointer position every time a key is pressed or released.
Only provide the position on demand. And explain that it's actually not very
useful as it's simply the same as the current mouse position.

Send wxEVT_CHAR_HOOK events to the focused window itself but make them
propagatable to ensure that the parent windows (including the top level
parent) still get it. This still allows the TLW parent to intercept keyboard
handling in its child but allows the child (or an intermediate parent window)
to have some say in the matter.
