Reimplemented in SubSupCell, and ExptCell.

◆ GetDrop()

wxCoord Cell::GetDrop ( ) const

inlineinherited

Get the distance between the center and the bottom of this cell.

This command returns the real line width when all line breaks are really performed. See GetFullWidth().

◆ GetMaxDrop()

int Cell::GetMaxDrop ( ) const

inherited

Returns the maximum distance between center and bottom of this line.

◆ GetNextToDraw()

Cell* Cell::GetNextToDraw ( ) const

inlineinherited

Get the next cell that needs to be drawn.

◆ GetSuppressMultiplicationDot()

bool Cell::GetSuppressMultiplicationDot ( ) const

inlineinherited

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 AnimationCell::GetToolTip ( wxPoint point ) const

overridevirtual

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.

inlineinherited

Get the width of this cell.

This value is recalculated by Recalculate()

◆ IsBrokenIntoLines()

bool Cell::IsBrokenIntoLines ( ) const

inlineinherited

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

inlineinherited

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.

◆ IsEditable()

bool Cell::IsEditable ( bool input = false ) const

inlineinherited

Is this cell editable?

Editable cells include comments, code, captions and questions from maxima.

◆ IsHidden()

bool Cell::IsHidden ( ) const

inlineinherited

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

Additionally folded GroupCells are marked as "hidden".

◆ PasteFromClipboard()

void Cell::PasteFromClipboard ( bool primary = false )

virtualinherited

Paste from the clipboard into this cell.

Parameters

primary Linux has two clipboards: One that automatically stores all selected test and that is pasted on middle-click (true) and the traditional copy-and-paste one (false). This parameter tells which clipboard to use.

Reimplemented in EditorCell.

◆ RecalculateList()

void Cell::RecalculateList ( AFontSize fontsize )

inherited

Recalculate both width and height of this list of cells.

Is faster than a RecalculateHeightList();RecalculateWidths();.

◆ ReloadTimer()

inherited

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

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

◆ Scale_Px() [2/2]

wxCoord Cell::Scale_Px ( double px ) const

inlineinherited

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 )

virtualinherited

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, SumCell, SubSupCell, SubCell, FunCell, and ExptCell.

◆ SetFrameRate()

int AnimationCell::SetFrameRate ( int Freq )

Set the frame rate of this AnimationCell [in Hz].

Parameters

Freq	The requested frequency [in Hz] or -1 for: Use the default value.

Returns: The frame rate that was actually set.

◆ SetIsExponent()

void Cell::SetIsExponent ( )

virtualinherited

Tell this cell to be an exponent.

Fractions in exponents are displayed as 1D maths

Reimplemented in FracCell.

◆ SetIsExponentList()

void Cell::SetIsExponentList ( )

virtualinherited

Tell this list of cells to be an exponent.

Fractions in exponents are displayed as 1D maths

◆ SetNextToDraw() [1/2]

virtual void Cell::SetNextToDraw ( Cell * next )

inlinevirtualinherited

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

◆ SetNextToDraw() [2/2]

template<typename T , typename Del , typename std::enable_if< std::is_base_of< Cell, T >::value, bool >::type = true>

void Cell::SetNextToDraw ( const std::unique_ptr< T, Del > & ptr )

inlineinherited

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.

◆ SetValue()

virtual void Cell::SetValue ( const wxString & WXUNUSEDtext )

inlinevirtualinherited

Allows to change the text a TextCell contains.

Todo:: Do we ever use this function?

◆ StopTimer()

void AnimationCell::StopTimer ( )

Stops the timer.

Also deletes the timer as on MSW there aren't many timers available.

◆ ToOMML()

wxString Cell::ToOMML ( ) const

virtualinherited

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

◆ Unbreak()

void Cell::Unbreak ( )

virtualinherited

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 ( )

virtualinherited

Unbreak this line.

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 list of cells to the single-line form.

◆ VariablesAndFunctionsList()

wxString Cell::VariablesAndFunctionsList ( ) const

inherited

Returns all variable and function names used inside this list of cells.

Used for detecting lookalike chars in function and variable names.

Field Documentation

◆ m_center

wxCoord Cell::m_center = -1

protectedinherited

The distance between the top and the insertion point of this cell.

◆ m_currentPoint

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

protectedinherited

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_height

wxCoord Cell::m_height = -1

protectedinherited

The height of this cell.
