Detailed Description

The base class all cell types the worksheet can consist of are derived from

Every Cell is part of two double-linked lists:

A Cell does have a member m_previous that points to the previous item (or contains a NULL for the head node of the list) and a member named m_next that points to the next cell (or contains a NULL if this is the end node of a list).
And there is m_nextToDraw that contain fractions and similar items as one element if they are drawn as a single 2D object that isn't divided by a line break, but will contain every single element of a fraction as a separate object if the fraction is broken into several lines and therefore displayed in its a linear form.

Also every list of Cells can be a branch of a tree since every math cell contains a pointer to its parent group cell.

Besides the cell types that are directly user visible there are cells for several kinds of items that are displayed in a special way like abs() statements (displayed as horizontal rules), subscripts, superscripts and exponents. Another important concept realized by a class derived from this one is the group cell that groups all things that are foldable in the gui like:

A combination of maxima input with the output, the input prompt and the output label.
A chapter or a section and
Images with their title (or the input cells that generated them)

Attention: Derived classes must test if m_next equals NULL and if it doesn't they have to delete() it.

On systems where wxWidget supports (and is compiled with) accessibility features Cell is derived from wxAccessible which allows every element in the worksheet to identify itself to an eventual screen reader.

◆ Copy()

virtual std::unique_ptr<Cell> Cell::Copy ( GroupCell * group ) const

pure virtual

Create a copy of this cell

This method is purely virtual, which means every child class has to define its own Copy() method.

Implemented in ImgCellBase, FullTestCell, GroupCell, EditorCell, AnimationCell, AbsCell, FunCell, IntervalCell, ParenCell, SetCell, ListCell, ConjugateCell, ExptCell, SqrtCell, SumCell, FracCell, IntCell, LimitCell, ImgCell, TextCell, LabelCell, DigitCell, LongNumberCell, SubSupCell, MatrCell, AtCell, DiffCell, and SubCell.

◆ Draw()

void Cell::Draw ( wxPoint point )

virtual

Draw this cell

Parameters

point The x and y position this cell is drawn at: All top-level cells get their position during recalculation. But for the cells within them the position needs a second step after determining the dimension of the contents of the top-level cell.

Example: The position of the denominator of a fraction can only be determined after the height of denominator and numerator are known.

Remember that (for example with double fractions) the center does not have to be in the middle of a cell even if this object is — by definition — center-aligned.

◆ GetCenterList()

int Cell::GetCenterList ( ) const

Returns the maximum distance between top and center of this line

Note that the center doesn't need to be exactly in the middle of an object. For a fraction for example the center is exactly at the middle of the horizontal line.

◆ GetLineWidth()

int Cell::GetLineWidth ( ) const

How many pixels is the current line of this list of cells wide?

Returns the first and last cells within the given rectangle, without recursing into the inner cells.

◆ GetMaxDrop()

int Cell::GetMaxDrop ( ) const

◆ GetNextToDraw()

Cell* Cell::GetNextToDraw ( ) const

inline

Get the next cell that needs to be drawn

In case of potential 2d objects like fractions either the fraction needs to be drawn as a single 2D object or the nominator, the cell containing the "/" and the denominator are pointed to by GetNextToDraw() as single separate objects.

wxRect Cell::GetRect ( bool all = false ) const

virtual

Get the smallest rectangle this cell fits in

Parameters

all	true: Get the rectangle for this cell and the ones that follow it in the list of cells false: Get the rectangle for this cell only.

Reimplemented in GroupCell.

◆ GetSuppressMultiplicationDot()

bool Cell::GetSuppressMultiplicationDot ( ) const

inline

Do we want to begin this cell with a center dot if it is part of a product?

Maxima will represent a product like (a*b*c) by a list like the following: [*,a,b,c]. This would result us in converting (a*b*c) to the following LaTeX code: \left(\cdot a ß\cdot b \cdot c\right) which obviously is one \cdot too many => we need parenthesis cells to set this flag for the first cell in their "inner cell" list.

◆ GetToolTip()

const wxString & Cell::GetToolTip ( wxPoint point ) const

virtual

Returns the ToolTip this cell provides at a given point.

Parameters

point The point in worksheet coordinates, must be inside the cell or else an empty string is returned.

Reimplemented in ImgCellBase, AnimationCell, and ImgCell.

◆ IsBrokenIntoLines()

bool Cell::IsBrokenIntoLines ( ) const

inline

Whether this cell is broken into two or more lines.

Long abs(), conjugate(), fraction and similar cells can be displayed as 2D objects, but will be displayed in their linear form (and therefore broken into lines) if they end up to be wider than the screen. In this case m_isBrokenIntoLines is true.

◆ IsComment()

bool Cell::IsComment ( ) const

inline

Determine if this cell contains text that isn't code

Returns: true, if this is a text cell, a title cell, a section, a subsection or a sub(n)section cell.

◆ IsHidden()

bool Cell::IsHidden ( ) const

inline

Whether this cell is not to be drawn.

Currently the following items fall into this category:

parenthesis around fractions or similar things that clearly can be recognized as atoms
plus signs within numbers
The output in folded GroupCells

◆ Recalculate()

void Cell::Recalculate ( AFontSize fontsize )

virtual

Recalculate the size of the cell and the difference between top and center

Must set: m_height, m_width, m_center.

Parameters

fontsize In exponents, super- and subscripts the font size is reduced. This cell therefore needs to know which font size it has to be drawn at.

Reimplemented in ImgCellBase, EditorCell, ImgCell, AbsCell, ParenCell, FunCell, FracCell, ExptCell, IntervalCell, ListCell, SqrtCell, SumCell, IntCell, LimitCell, TextCell, SubSupCell, LabelCell, AtCell, DiffCell, DigitCell, LongNumberCell, MatrCell, and SubCell.

◆ RecalculateList()

void Cell::RecalculateList ( AFontSize fontsize )

◆ ResetData()

void Cell::ResetData ( )

Mark all cached size information as "to be calculated".

Resets remembered size and position info for this cell and all cells inside it

Resets cached data like width and the height of the current cell as well as the vertical position of the center. Then repeats this with

◆ Scale_Px()

int Cell::Scale_Px ( double px ) const

inline

Scale font sizes and line widths according to the zoom factor.

Is used for displaying/printing/exporting of text/maths

◆ SetAltCopyText()

void Cell::SetAltCopyText ( const wxString & text )

virtual

What should end up if placing this cell on the clipboard?

AltCopyTexts for example make sense for subCells: a_n looks like a[n], even if both are lookalikes and the cell therefore needs to know what to put on the clipboard if this cell were copied. They also make sense in many other places we may never have thought about. But since we seriously want to save memory space on the ubiuitous TextCells it might be scary to apply this principle to them, at least if you know that text you copy from the internet to a terminal might contain additional commands with TextSize=0...

Reimplemented in TextCell, ExptCell, FunCell, SumCell, SubSupCell, and SubCell.

◆ SetNextToDraw()

virtual void Cell::SetNextToDraw ( Cell * next )

inlinevirtual

Tells this cell which one should be the next cell to be drawn

If the cell is displayed as 2d object this sets the pointer to the next cell.

If the cell is broken into lines this sets the pointer of the last of the list of cells this cell is displayed as.

Reimplemented in FracCell, FunCell, ParenCell, AbsCell, IntCell, IntervalCell, SumCell, ListCell, SqrtCell, LimitCell, ConjugateCell, DiffCell, and LongNumberCell.

◆ SetToolTip()

void Cell::SetToolTip ( const wxString * tooltip )

Set the tooltip of this math cell - it must be exist at least as long as the cell does. Translation results behave that way. I.e. it must be a static string!

◆ ToOMML()

wxString Cell::ToOMML ( ) const

virtual

Returns the cell's representation as OMML

If this method returns wxEmptyString this might mean that this cell is better handled in RTF; The OOML can later be translated to the respective RTF maths commands using OMML2RTF.

Don't know why OMML was implemented in a world that already knows MathML, though.

Reimplemented in FracCell, ParenCell, AbsCell, FunCell, IntCell, IntervalCell, ExptCell, ListCell, SqrtCell, SumCell, TextCell, LimitCell, SubSupCell, MatrCell, AtCell, DiffCell, and SubCell.

◆ ToRTF()

virtual wxString Cell::ToRTF ( ) const

inlinevirtual

Returns the cell's representation as RTF.

If this method returns wxEmptyString this might mean that this cell is better handled in OMML.

Reimplemented in ImgCellBase, GroupCell, EditorCell, ImgCell, and TextCell.

◆ Unbreak()

void Cell::Unbreak ( )

virtual

Undo breaking this cell into multiple lines

Some cells have different representations when they contain a line break. Examples for this are fractions or a set of parenthesis.

This function tries to return a cell to the single-line form.

Reimplemented in SumCell.

◆ UnbreakList()

void Cell::UnbreakList ( )

virtual

Unbreak this line

Some cells have different representations when they contain a line break. Examples for this are fractions or a set of parenthesis.

Member Data Documentation

◆ m_currentPoint

wxPoint Cell::m_currentPoint {-1, -1}

protected

The point in the work sheet at which this cell begins.

The begin of a cell is defined as

x=the left border of the cell
y=the vertical center of the cell. Which (per example in the case of a fraction) might not be the physical center but the vertical position of the horizontal line between numerator and denominator.

The current point is recalculated

for GroupCells by GroupCell::RecalculateHeight
for EditorCells by it's GroupCell's RecalculateHeight and
for Cells when they are drawn.

◆ m_group

CellPtr<GroupCell> Cell::m_group

protected

The GroupCell this list of cells belongs to.

◆ m_nextToDraw

CellPtr<Cell> Cell::m_nextToDraw

protected

The next cell in the draw list. This has been factored into Cell temporarily to reduce the change "noise" when it will be subsequently removed.

◆ m_toolTip

const wxString* Cell::m_toolTip

protected

This tooltip is owned by us when m_ownsToolTip is true. Otherwise, it points to a "static" string.
