Detailed Description

A cell grouping input (and, if there is one, also the output) cell to a foldable item

Items where a list of groupcells can be folded include

sections
chapters
The prompt (if maxima outputs one) with the input cell, the output label maxima might generate and the output cell (if there is any output)
A combination of image and title
A combination of image and input cell

This GroupCell stores the currently hidden cells in the GroupCell m_hiddenTree. This tree has the parent m_hiddenTreeParent.

Member Function Documentation

◆ AddEnding()

bool GroupCell::AddEnding ( )

overridevirtual

Add a semicolon to a code cell, if needed.

Defined in GroupCell and EditorCell

Reimplemented from Cell.

◆ BreakUpCells()

bool GroupCell::BreakUpCells ( Cell * cell )

Attempt to split math objects that are wider than the screen into multiple lines.

Return values

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

◆ CellUnderPointer()

void GroupCell::CellUnderPointer ( GroupCell * cell )

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.

◆ Copy()

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

overridevirtual

Create a copy of this cell

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

Implements Cell.

◆ Draw()

void GroupCell::Draw ( wxPoint point )

overridevirtual

Draw this GroupCell

Also assigns all output cells contained in this GroupCell a y coordinate.

Attention: The height the output has needs to be in sync with the height calculation done during RecalculateAppended() and during RecalculateOutput().; The y position used here must be in sync with the one calculated by RecalculateOutput().

Reimplemented from Cell.

◆ Fold()

GroupCell * GroupCell::Fold ( )

Fold this cell

Returns: the cell's address if folding was successful, else NULL

◆ FoldAll()

GroupCell * GroupCell::FoldAll ( )

Fold all cells

Returns: the cell's address if folding was successful, else NULL

◆ GetInnerCell()

Cell* GroupCell::GetInnerCell ( int index ) const

inlineoverridevirtual

Retrieve an inner cell with given index which must be less than GetInnerCellCount.

Reimplemented from Cell.

◆ GetLabel()

Cell* GroupCell::GetLabel ( ) const

inline

Returns the list of cells the output consists of, starting with the label.

◆ GetLastWorkingGroup()

GroupCell * GroupCell::GetLastWorkingGroup ( ) const

Which GroupCell was the last maxima was working on?

Must be kept in GroupCell as on deletion a GroupCell will unlink itself from this pointer.

◆ GetOutput()

Cell* GroupCell::GetOutput ( ) const

inline

Returns the list of cells the output consists of, starting after the label.

◆ GetRect()

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

overridevirtual

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 from Cell.

◆ GetToolTip()

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

overridevirtual

Returns the tooltip for the element at the position point.

wxEmptyString means: No toolTip.

Reimplemented from Cell.

◆ HideTree()

bool GroupCell::HideTree ( std::unique_ptr< GroupCell > && tree )

Fold the current cell

Returns

false, if the cell already was folded when this function was called
true, if the cell was folded by this function call.

◆ IsFoldable()

bool GroupCell::IsFoldable ( ) const

folding and unfolding

Is this cell foldable?

◆ IsLesserGCType()

bool GroupCell::IsLesserGCType ( GroupType comparedTo ) const

Document structure: Can this cell type be part of the contents of comparedTo?

For example ordinary text cells can be part of a chapter and sections can be part of a chapter, too.

◆ Recalculate()

void GroupCell::Recalculate ( AFontSize WXUNUSEDfontsize )

inlineoverride

Recalculates the size of this GroupCell and all cells inside it if needed.

This command will also assign the GroupCell a y coordinate it is plotted at. The y coordinate of all output cells of this GroupCell is assigned during GroupCell::Draw() by providing Cell::Draw() with the cell's coordinates.

◆ RecalculateOutput()

void GroupCell::RecalculateOutput ( )

Recalculate the height of the output part of the cell

Attention: Needs to be in sync with the height calculation done during Draw() and during RecalculateAppended.

◆ RemoveOutput()

void GroupCell::RemoveOutput ( )

Remove all output cells attached to this one

If called on an image cell it will not remove the image attached to it (even if the image technically is the first output cell attached to an image cell) but it will remove eventual error messages attached to the image.

◆ ResetInputLabel()

void GroupCell::ResetInputLabel ( )

Reset the input label of the current cell.

Won't do nothing if the cell isn't a code cell and therefore isn't equipped with an input label.

◆ RevealHidden()

bool GroupCell::RevealHidden ( )

Unfold all that is needed to make the current cell seen

Returns

false, if the cell already was visible on calling this function
true, if cells were unfolded by this function call

Unfold a tree from the bottom up, when a hidden cell needs to be seen.

Returns: true if any cells were unfolded.

◆ SetHiddenTreeParent()

void GroupCell::SetHiddenTreeParent ( GroupCell * parent )

Set the parent cell of hidden cells.

For every cell in this GroupCell, set m_hiddenTreeParent to parent. This way, the field can be used to traverse up the tree no matter which child we are on. In other words, every child knows its parent node.

◆ ToRTF()

wxString GroupCell::ToRTF ( ) const

overridevirtual

Returns the cell's representation as RTF.

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

Reimplemented from Cell.

◆ ToTeX()

wxString GroupCell::ToTeX	(	wxString	imgDir,
		wxString	filename,
		int *	imgCounter
	)		const

Convert the cell to TeX code

Parameters

imgDir	The directory eventual images should be stored in
filename	The base filename for all images
imgCounter	The location of the counter that tells how many unique image filenames we have already generated. NULL means: This TeX export doesn't contain other GroupCells that can export images and therefore need to enumerate them.

◆ Unfold()

GroupCell * GroupCell::Unfold ( )

Unfold this cell

Returns: the last cell that was unfolded.

◆ UnfoldAll()

GroupCell * GroupCell::UnfoldAll ( )

Unfold all cells

Returns: the last unfolded cell's address if unfolding was successful, else NULL
