Drag-resizing the columns didn't work correctly when using the native
header and scrolling it horizontally, as the wrong offset was used in
this case.
Fix the offset in wxGrid code and add a unit test checking that this
works as intended (at least under MSW, as wxUIActionSimulator just
doesn't work reliably enough to test for this under the other platforms,
and, besides, only MSW has the native header control implementation
anyhow).
While feacaf8714 changed the API to allow
using any wxWindow (and not only a window of a wxControl-derived class)
as the associated window of the grid editor, actually doing resulted in
an immediate crash due to dereferencing a null pointer in wxGrid code
which still expected to have a wxControl.
Fix this by replacing all calls to wxGridCellEditor::GetControl() inside
wxGrid with wxGridCellEditor::GetWindow(), to ensure that a non-null
editor window is used even in this case.
Closes https://github.com/wxWidgets/wxWidgets/pull/1509
The various arrays containing row/column coordinates (m_rowHeights,
m_rowBottoms, m_colWidths, m_colRights) must not be accessed directly as
they are empty by default, and are only initialized if any rows/columns
have non-default width/height.
Use safe accessor functions instead.
See https://github.com/wxWidgets/wxWidgets/pull/1417
CellToGridWindow(), added by frozen rows/columns patch, returned NULL
when called with invalid row/col arguments and this could happen if any
of several methods using m_currentCellCoords were called during wxGrid
initialization, while m_currentCellCoords was still (-1, -1).
Fix this by testing for this case explicitly and returning the main grid
window, which is never NULL, instead.
Closes#18454.
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.
Instead of doing it in overridden wxGridWindow::ScrollWindow(), do it
from wxGrid::ScrollWindow() itself, this makes more sense and will make
it easier to generalize it to scroll more windows.
No real changes yet.
Add two simple helpers: SetNativeHeaderColCount() and
SetNativeHeaderColOrder() and call the latter from the former to ensure
that the columns order is always correct when switching to the native
control.
This simple function combines BlockToDeviceRect() and
wxWindow::Refresh() calls and allows to avoid the ugly casts in
wxGridSelection code as well as making the code slightly shorter and
more clear.
No real changes.
Use wxWindow instead of wxControl in wxGridCellEditor to allow using
any window as an editor control, as it doesn't need to be a wxControl.
Closes https://github.com/wxWidgets/wxWidgets/pull/1370
Combination of multiple borders looks bad, so skip drawing the left/top
borders in wxGrid{Row,Col,Corner}LabelWindow if wxGrid already has a
border around it.
Grid contents was drawn in grey colour instead of the usual active one
when it was disabled, but the row and column labels kept their default
appearance, which looked out of place.
Fix this by greying them out too. This should have been arguably done in
73145b0ed1 ~17 years ago, but better late
than never.
This is a minor optimization and can significantly reduce flicker in a
not uncommon case when SetCellValue() is used to refresh all or many of
the grid cells if only few of them actually change.
See #9717.
Closes https://github.com/wxWidgets/wxWidgets/pull/1276
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
This solves backward incompatibility problem introduced in 2d8bbbe3c9.
The name of base class for grid header renderers hierarchy is restored
to be wxGridHeaderLabelsRenderer. This introduces another problem: now
wxGridCornerHeaderRenderer is derived from wxGridHeaderLabelsRenderer,
not vice versa, as it was before. But it is considered less disruptive
change, compared to base class rename.
Now, every header cell can have a label, including the corner one,
so wxGridHeaderLabelsRenderer::DrawLabel() was moved up one level
in the inheritance chain. Class names were changed accordingly.
Actual storage of corner label is delegated to a grid table class,
just because it is already done that way for column and row labels.
Ignore all the mouse events other than "left up" while dragging to avoid
releasing the mouse and ending the dragging operation too soon.
This required non-trivial refactoring of the code which hopefully should
also make it slightly more clear by centralizing high level logic in
ProcessGridCellMouseEvent() itself and calling various helper functions
from it instead of spreading this logic over the entire call tree.
The code still remains pretty confusing and rewriting it to use
wxMouseEventsManager (which would need to be generalized first to become
a template class using arbitrary item type instead of just "int", as
now) would undoubtedly do it a lot of good.
Closes#18186.
No real changes, just refactor the code to extract the part of
CancelMouseCapture() which can be useful not only when the mouse capture
is lost unexpectedly, but also when we release it of our own volition,
into a separate function.
Use wxDCClipper, now that it doesn't lose the previously set clipping
region any more, in wxGridCellStringRenderer::Draw() to ensure that we
don't overflow the area allocated for the cell.
Closes#17872.
Account for the empty lines explicitly by reserving enough vertical
space for them, as wxDC::GetTextExtent() wouldn't do it as it simply
returns 0 for empty strings.
Closes#18028.
This resulted in a crash in GetDefaultEditorForCell() later when GetEditor()
was called from HideCellEditControl() which is itself always called from
wxGrid dtor because GetDefaultEditorForCell() dereferenced m_table without
checking if it was not null any more.
Add the missing check to this function and GetDefaultRendererForCell() too,
for consistency.
In addition, dismiss the cell editor immediately when changing table instead
of doing it at some later time, as it just doesn't make sense to continue
showing it any more as the data it was started to edit doesn't belong to us
any longer.
These grid table requests seem to have been never used and were not doing much
in wxGrid neither, moreover they were never documented, so just stop
supporting them.
wxGridTableBase::SetAttr (for cells) does check its attr parameter for
nullptr, but the check was missing from the row and column functions.
Adding it makes it possible to use a nullptr argument to reset the
attributes.
Use GetRowHeight()/GetColWidth() instead of accessing m_rowHeights/m_colWidths
arrays directly as the functions handle the hidden rows/columns correctly.
This fixes bug with corruption of wxGrid appearance if any rows/columns were
inserted into or deleted from a grid containing some hidden rows/columns.
Closes#16980.
This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.

This is not necessary as wxDC already inherits RTL from the window itself and,
in fact, breaks the display when using RTL.

Ensure that the table pointer inside wxGrid is updated before initializing the
native column header as it uses wxGrid::GetColLabelValue() which doesn't work
correctly without a valid table pointer.

Fix the logic for finding the correct position to drop the column at when
ending a drag move operation. The old code dropped it one position too far to
the left when it was dropped on the "far" (i.e. right with LTR layout) part of
the target column.
See #16110.

Using negative column widths used for hidden columns when updating the column
positions after dragging one of them to a new position totally broke their

Allow the renderer to specify the best height at the given width (or vice
versa) instead of the best size in both direction which is not defined for
e.g. wxGridCellAutoWrapStringRenderer.

Replace them with wxFONTWEIGHT_BOLD, wxFONTSTYLE_NORMAL or wxFONTWEIGHT_NORMAL
and equivalents in the code of the library itself and in the samples.
Also simplify font construction using wxFontInfo where possible to avoid
specifying these constants at all if they are not needed.

The number of columns in the table is now (since r60717) stored in m_numCols,
so there is no need to get it from wxGrid any more. This is not only simpler
and faster but also more correct as the first row might not have the full
number of values yet.
Closes#15809.

Replacement of FUTURE_WXWIN_COMPATIBILITY_3_0 with WXWIN_COMPATIBILITY_3_0 in
r75532 resulted in tons of warnings as all code using wxSOLID and similar
constants now uses the deprecated methods taking int instead of the preferred
ones taking wx{Pen,Brush}Style (and similarly for wxFont{Style,Weight,Family}).
Fix all of them but this also would seem to mean that this change might not be
such a good idea at all.
