Detailed Description

A specialized GroupCell that provides empty vertical space for alignment.

When two or three files are compared and one file lacks a cell that exists in the others, this cell is inserted as a placeholder to keep the corresponding cells in the other worksheets aligned horizontally.

Member Function Documentation

◆ AddEnding()

bool GroupCell::AddEnding ( )

overridevirtualinherited

Add a semicolon to a code cell, if needed.

Defined in GroupCell and EditorCell

Reimplemented from Cell.

◆ BreakLines_List()

void Cell::BreakLines_List ( ) const

inherited

Break lines in this list of cells.

The layout process follows a three-step mechanism to ensure that mathematical expressions and text fit within the available horizontal space of the worksheet:

Reset to 2D Form: All cells are first reset to their "beautiful" 2D representation using UnBreakUpCells(). This ensures we start with the most compact and readable form.
Recursive Breakup: The algorithm identifies any 2D objects (like fractions, parenthesis, or long numbers) that are wider than a certain percentage of the screen. These objects are told to "BreakUp()", which typically means converting themselves into a linearized 1D form (e.g., a fraction a/b becomes (a)/(b)). This process is recursive; if the inner components are still too wide, they will be broken up further.
Line Wrapping: Once all objects are either small enough or in their 1D form, the final layout pass iterates through the flattened list and inserts "soft line breaks" whenever the cumulative width would exceed the line's limit. This pass also handles indentation for subsequent lines of the same expression.

◆ BreakUp()

bool Cell::BreakUp ( ) const

virtualinherited

Try to split this command into lines to make it fit on the screen.

Return values

true	= This cell was split into lines.

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

◆ BreakUpAndMark()

void Cell::BreakUpAndMark ( ) const

protectedinherited

Break up the internal cells of this cell, and mark it as broken up.

Sets the cell's size to 0, as in broken up state the contents of the cell will be displayed in 1D mode while this cell won't be displayed, at all.

◆ BreakUpCells()

bool Cell::BreakUpCells ( ) const

inherited

Cell list: Convert 2d math objects bigger than the screen width into linear form.

Return values

true,if this action has changed the height of cells.

◆ CanCopy()

virtual bool Cell::CanCopy ( ) const

inlinevirtualinherited

Select Can we copy the editable text of this cell?

Reimplemented in EditorCell.

◆ CanPopOut()

virtual bool Cell::CanPopOut ( ) const

inlinevirtualinherited

Reimplemented in AnimationCell, ImgCell, and ImgCellBase.

◆ CellsInListRecursive()

unsigned long Cell::CellsInListRecursive ( ) const

inherited

How many cells does this cell contain?

The number of cells the current group contains (-1, if no GroupCell)

◆ CellUnderPointer()

void GroupCell::CellUnderPointer ( GroupCell * cell )

inherited

Marks the cell that is under the mouse pointer.

Is kept in GroupCell so every GroupCell can decide it is no more under the pointer once it has been deleted from the worksheet.

◆ ClearCache()

virtual void Cell::ClearCache ( )

inlinevirtualinherited

Clears memory from cached items automatically regenerated when the cell is drawn.

The scaled version of the image will be recreated automatically once it is needed.

Reimplemented in AnimationCell, ImgCell, and ImgCellBase.

◆ ClearCacheList()

void Cell::ClearCacheList ( )

inherited

Clears the cache of the whole list of cells starting with this one.

For details see ClearCache().

◆ ContainsPoint()

bool Cell::ContainsPoint ( wxPoint point ) const

inlineinherited

Is a given point inside this cell?

Parameters

point The point to test for collision with this cell

◆ ContainsRect()

bool Cell::ContainsRect	(	const wxRect &	sm,
		bool	all = `true`
	)		const

inherited

Is a part of this cell inside a certain rectangle?

Parameters

sm	The rectangle to test for collision with this cell
all	true means test this cell and the ones that are following it in the list false means test this cell only.

◆ Copy()

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

inlineoverridevirtual

Create a copy of this cell.

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

Reimplemented from GroupCell.

◆ CopyToClipboard()

virtual bool Cell::CopyToClipboard ( ) const

inlinevirtualinherited

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.

◆ 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...
