This class was a strange hybrid of a container/view/range and iterator,
as it both provided begin()/end() container-like methods and
iterator-like methods for dereferencing/advancing.
Simplify this by removing the latter part and making this class really
just a range, with its own iterator class in order to avoid leaking the
exact type of the iterator used in the API.
Note that while it's now completely trivial, it is still useful as it
isolates the application code from the vector used to store the selected
blocks currently and will allow to change internal representation in the
future without breaking the existing code.
Store all types of selection with an array of blocks instead of arrays of
cells, blocks, rows and columns.
It (hopefully) simplifies the code and allows us to implement editing of
the last selection block much easier.
This makes it possible to use wxObjectDataPtr inside functions returning
raw pointers owned by the caller, such as custom GetAttr() in the grid
sample.
In many case SetTable() is called with its takeOwnership parameter set
to true, as shown by the grid sample in which all 3 of the calls to
SetTable() set it to true, but calling it in this case is awkward, as
bare "true" in the caller is unreadable and almost invariably requires
an explanatory comment.
Improve the API by adding AssignTable(), which is the same to SetTable()
as the existing AssignImageList() to SetImageLabel(), which always takes
ownership of the table pointer.
It is convenient to have this function if only in order to be able to
call GetGridColHeader() safely, i.e. without triggering an assert if
native header is not being used.
The behaviour of these functions for the tools containing controls is
counter-intuitive but changing it now would silently break existing code
working around the current semantics, so just document it instead.
See #16552.
This doesn't work anyhow, so it's better to prevent the code doing this
from compiling instead of getting run-time asserts or worse.
Also simplify construction of these events inside wxWidgets by passing
the window itself to the ctor instead of passing just its ID and calling
SetEventObject() separately later.
For consistency, do the same thing for wxNcPaintEvent too.
This allows to give at least some explanation about why the secrets
can't be stored to the user, e.g. they could search for a message such
as
The name org.freedesktop.secrets was not provided by any .service files
to find out that gnome-keyring package needs to be installed on their
system.
Note that this change means that under Unix an attempt to connect to the
secret service is now made when wxSecretStore is constructed and not
just when it's used for the first time, as before.
Provide GetAttrPtr() and GetCellAttrPtr() convenience functions that can
be used instead of the original Ptr-less versions to avoid the need to
manually call DecRef() on the returned wxGridCellAttr pointers.
No real changes, just simplify the code and make it safer.
