Just add a call to SetTextColoursAndFont() now that it is present in
this renderer base class (see the parent commit) to ensure that the
correct, i.e. corresponding to the column attribute, colour is used for
the stars.
Multiply the number of rows in the grid sample by a factor of 10. This
demonstrates the slowness with attribute lookups better when using
checkered (Ctrl+Shift+K) or coloured (Ctrl+Shift+L) cells, as filling
the grid is slowed down by way more than a factor of 10. Scrolling also
becomes less responsive the further away from the home cell the view is.
As a result of increasing the row count also move the cells positioned
near the end of the grid there again, and don't use fixed coords for
them.
Add options to fill grid either half (checkered cells) or fully (all
cells coloured) with attributes. Available from Grid > "Toggle Checkered
Cells" and "Toggle Coloured Cells".
Only single insertions of rows and columns were supported, allow N
insertions provided the row/column selection is consecutive.
Do the same for deletions: while deleting selected rows and columns
already works it's useful to test deleting multiple positions at once.
Avoid duplicating the complicated logging code twice, when it's exactly
the same for both the SELECTED and SELECTING events. Just use a common
helper function instead.
Add a helper class making it easier to define activation-only editors
and use it to implement MyGridStarEditor in the sample, showing a
typical example of using such editor.
The changes of the commit 393f5c8e2b (Use less arbitrary column/row
sizes in the grid sample, 2020-03-31) accidentally made this column
narrower than default instead of making it wider due to a typo in the
name of wxGrid method: it should be the default column size, not the
default column label size.
This seems to be more consistent with the existing functions and doesn't
create ambiguity with a grid range.
Also rename wxGridSelectionRange to just wxGridBlocks as, in principle,
this class could be used for iterating over any blocks, not just the
selected ones.
No changes in functionality, this is just a renaming.
Show the selected cells/rows/columns/blocks instead of just showing
their number, as we now have an efficient (i.e. taking time proportional
to the number of selected blocks and not to the number of the individual
cells, rows or columns) way of doing this.
See #2576.
Since the changes in a40acbb28e (Add CanOverflow function to
wxGridCellAttr, 2020-02-06), cells with non-default vertical alignment
didn't overflow any more, even if their horizontal alignment was
unchanged and still defaulted to left-aligned.
This was due to assuming that if the alignment of wxGridCellAttr itself
was different from wxALIGN_LEFT, it meant that it wasn't left-aligned,
which seems logical but is in fact false, as the alignment can also be
wxALIGN_INVALID, in which case the real alignment is taken from the
default grid attribute.
Fix this by using GetNonDefaultAlignment() to get the alignment value
effectively used and add a unit test, as well as an example in the
sample, showing that this now works correctly.
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.
This API is not implemented yet, i.e. ellipsization mode is not
respected for now. This commit just adds the API, documents it and adds
an example of using it in the sample.
Replace "bool overflow" flag with a class allowing to specify the same
overflow/clipping behaviour currently, but also allowing to extend it,
notable to add ellipsization support, in the future.
Preserve the existing API by reimplementing it in terms of the new one.
Also update the same to demonstrate a cell which always overflows,
independently of the default cell behaviour.
Add labels for the columns using date format and labels for the cells
using date renderer/editor explicitly to give a better idea about what's
going on here.
Also use the same rows numbers for date cells as for the column ones for
consistency.
No real changes.
See 659ab78c6d
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
Add wxGrid::FreezeTo() method which allows to freeze the given number of
columns and/or rows at the beginning of the grid, i.e. keep them pinned
in place while the rest of the grid is scrolled.
The main wxGridWindow (m_gridWin) now corresponds to the non-frozen part
of the grid, with up to 3 new similar windows for the frozen
rows/columns and the frozen corner cells (which only exist if both rows
and columns are frozen) being additionally used.
Doing this involved adding "wxGridWindow*" parameter to many functions
that previously only worked with m_gridWin itself and addressing
additional complications, such as mouse events that can now cross
different windows.
See https://github.com/wxWidgets/wxWidgets/pull/952 for the original
version of the changes.
The "Native" menu item actually only toggled drawing native-lookalike
labels, but didn't use wxHeaderCtrl as could be expected. Rename the
existing menu item to "Native-like" and add the new "Native" one which
really enables the use of wxHeaderCtrl.
Add wxGridCellDateRenderer and wxGridCellDateRenderer which can be used
for the grid cells containing only dates, without times.
Also add wxGrid::SetColFormatDate() convenience function.
Refactor wxGridCellDateTimeRenderer slightly to reuse its code.
Closes https://github.com/wxWidgets/wxWidgets/pull/1101
Pass wxStrings directly to wxString::Format("%s") and similar
pseudo-vararg functions, there is no need for c_str() there since
wxWidgets 2.9.
Closes https://github.com/wxWidgets/wxWidgets/pull/1009
Still use Connect() in unit tests which were written explicitly for it
and in EventConnector, which can't use Bind() as it uses a variable for
the event type.
No real changes, just use the newer and more convenient function.
Allow to quickly check that cell/block/row/column selection works as expected.
This could be made more detailed, e.g. by dumping all the selected cells/rows/
columns if there are not too many of them, but for now this will do.
