Don't try to extend the existing selected blocks to rows/columns, this
contradicts the documented behaviour which is to discard the selected
blocks that become invalid in the new mode.
Do handle switching to wxGridSelectRowsOrColumns mode, as there doesn't
seem to be any reason not to.
Update the tests to check for the expected selection update behaviour.
Change the return type of this function to a simple and clear bool
instead of 3-valued int requiring a special explanation. This is simpler
and not any less efficient as checking for whether one block contains
another or the other one contains this one are separate operations
anyhow.
Rename the function to a more grammatically correct name.
Also move it inline as it's now trivial enough for this to be worth it.
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.
Really edit the current selection block instead of storing the temporary
information about the current selection and applying it on releasing Shift
key or LKM.
VZ: [...] this is not used by wxGrid itself and SendEvent() is not part
of the public API, so we never made any promises about being able to call
it with wxEVT_GRID_RANGE_SELECT.
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.
Line height calculation based on the font size is not right for wxGTK3
because native buttons (used as in-line editor buttons) don't scale down
well and they are not displayed properly within the line.
Minimal button size when the label is displayed properly is 35 so this
has to be minimal line height under wxGTK3.
Closes#18715.
For the sake of consistency with editor buttons created with
wxPropertyGrid::GenerateEditorButton(), the borders around the buttons
should be taken into account while positioning the buttons
in wxPGMultiButton.
Check that creating a wxTextCtrl doesn't generate any events to verify
that this problem doesn't exist in other ports, after fixing it in
wxGTK in 3e7e7dd24c (Avoid generating wxEVT_TEXT when wxTextCtrl initial
value is not empty, 2020-04-01).
