mgMathBox Class Reference

#include <MathBox.h>

List of all members.

Detailed Description

A window using a mcMathOrSystem to create the ouput.

mgMathBox class works as a normal wxWindow; so you can allocate, delete or copy mgMathBox windows without problems.

mgMathBox can be considered as a "math text control": a control where math expressions can be typed using all MathCore and MathGUI facilities.

Through EnableXXXX() and DisableXXXX() you can modify the behaviour of the window.

Constructor & Destructor Documentation

mgMathBox::mgMathBox ( const mgMathBox & tocopy ) [inline]

Copy constructor.
Deep copies the given mgMathBox into this object.
Parameters:

tocopy The box to copy.

Definition at line 284 of file MathBox.h.
References DeepCopy().

virtual mgMathBox::~mgMathBox ( ) [inline, virtual]

Destructor.
Destroys everything associated with this window, also math data.
Definition at line 288 of file MathBox.h.

Member Function Documentation

void mgMathBox::CheckReturnFlag ( int res )

Checks the return code of the mcElement::MoveCursor function.
Essentially, this function deselects the math expression if an user clicked on an area not containing any element.
Definition at line 427 of file MathBox.cpp.

void mgMathBox::DeepCopy ( const mgMathBox & )

Copies in this object all the data of the given mathbox.
The mathdata associated with this object after a deep copy will be totally independent from original data.
Definition at line 191 of file MathBox.cpp.
References m_bProcSpecialChar, m_mathContent, and m_rcSelection.
Referenced by mgResizeableMathBox::DeepCopy(), and mgMathBox().

bool mgMathBox::Export ( bool bXHTML,

wxOutputStream & str,

const wxString & title,

bool bUpperTag = FALSE,

bool bMPSupp = FALSE,

bool bUseNS = FALSE,

const wxString & ns = wxEmptyString,

const wxString & href = wxEmptyString,

int indstep = 2

) const

Exports the math data and works exactly as the other Export overload but it accepts a wxOutputStream instead of a file name.

Parameters:

str The output stream where all the XHTML/XML data is copied.

Definition at line 1199 of file MathBox.cpp.
References m_mathContent.

bool mgMathBox::Export ( bool bXHTML,

const wxString & filename,

const wxString & title,

bool bUpperTag = FALSE,

bool bMPSupp = FALSE,

bool bUseNS = FALSE,

const wxString & ns = wxEmptyString,

const wxString & href = wxEmptyString,

int indstep = 2

) const

Just choose a filename and a title for a new page, and this function will magically create a complete file containing all the mathematical data currently displayed in this window.
Because of the lack of a MathML implementation on Internet Explorer, this function will also inform the user, if the program is running on a Win32 system, that he will need an external program to view the file with IE: a link to MathPlayer homepage will be displayed.
This function can export the data both as XHTML and as XML. The differences between the two files are just on the headers, but the XML file needs some external XSL files (the XML file that is created is linked with the XSL files of MathStudio 'XSL' subfolder with absolute path link).

Parameters:

bXHTML If TRUE, an XHTML is exported; otherwise a pure XML file.

filename The name of a new XHTML/XML file that will be created.

title The title of the new XHTML/XML file.

bUpperTag If TRUE, tags are exported in UPPERCASE.

bMPSupp If TRUE, then math player support is enabled, adding some specific tags...

bUseNS If TRUE, then a namespace is used for MathML tags.

ns If bUseNS == TRUE, then this is the namespace used.

href

indstep NOT WORKING

Returns:
TRUE if everything went okay. FALSE if something was wrong; if something was wrong, the function will also advise the user with a message box.

void mgMathBox::ForceBmpUpdate ( )

Forces the update of the entire math contents.
This function should not be used to often if you want to avoid flickering.

wxString mgMathBox::GetExportPreview ( bool bXHTML,

bool bUpperTag = FALSE,

bool bMathPlayerSupport = FALSE,

bool bUseNS = FALSE,

const wxString & ns = wxEmptyString,

const wxString & href = wxEmptyString,

int indentstep = 2

) const

Returns an (usually) huge wxString containing the exported XHTML/XML math data.
It accepts the same parameters as the Export function.

References Export().

wxXml2Node mgMathBox::GetMathML ( bool bGetPresentation ) const [inline]

Returns the root node associated with the mcMathOrSystem contained in this box.

void mgMathBox::RedrawMath ( wxDC & dc,

int x,

int y

)

Redraws the math contents on the screen, after hiding the caret.
This function automatically calls UpdateCaret() before exiting, so that the caret is restored, if necessary. Since drawing could be corrupted if done when the caret is blinking in the blit area, the direct call m_mathContent.gui_DrawBmp(....); should NEVER be used.
Definition at line 400 of file MathBox.cpp.
References mgCaret::ForceHide(), GetCaret(), m_mathContent, and UpdateCaret().
Referenced by ForceBmpUpdate(), and UpdateMathBmp().

void mgMathBox::SetClientEvtHandler ( wxEvtHandler * p ) [inline]

Sets the client event handler which will receive the mgEVT_ACTIVE_ELEM_CHANGED notification events.
By default, client event handler is set, by constructor, as the parent window. Use NULL to disable mgEVT_ACTIVE_ELEM_CHANGED notification events.
Definition at line 338 of file MathBox.h.
References m_pClient.

void mgMathBox::SetSizeHintsToFitContents ( )

Sets the size hints for this window.
Setting "size hints" means that, after this call, this window will not be able to have a size smaller than the contents size.
Definition at line 252 of file MathBox.cpp.
References FitContents(), and GetContentSize().

void mgMathBox::UpdateContentPos ( )

Updates the math content's position using the current client size.
This function alters the m_ptPos variable.

References GetContentSize(), and m_ptPos.
Referenced by FitContents(), and ResetGUI().

int mgMathBox::UpdateMathBmp ( long flags,

const wxPoint & p = wxDefaultPosition

)

Updates the bitmap in the mcMathLine structure for the n-th line, using the given flags (and eventually the given point object).
If mcMathSystem::gui_NeedsRefresh() returns TRUE after the update, then the function redraws the math bitmap (without erasing the background or calling the Refresh() function to avoid flickering).
Parameters:

flags The flags given to the mcMathSystem::gui_UpdateBmp function.

p A valid wxPoint class, if you want to save in the bitmap also an eventual activation state.

Returns:
The ID of the active element.

bool mgMathBox::bUseNativeNewLines = TRUE [static]

If TRUE, then all the strings exported by the IO functions and by the GUI functions which output strings in the clipboard, will contain newlines encoded in the native format of the OS this program is running on.
If FALSE, all strings exported will contain newlines as "\n" (which are not correctly recognized as newlines under win32 and mac).

mgMathBoxCmd mgMathBox::cmd [static]

Initial value:
{ { mgMBC_CUT, wxT("Cut") }, { mgMBC_COPY_ASPLAIN, wxT("Copy as plain text") }, { mgMBC_COPY_ASMATHML, wxT("Copy as MathML") }, { mgMBC_PASTE, wxT("Paste") }, { mgMBC_SELECTALL, wxT("Select all") }, { mgMBC_CREATENEW_ANDLINE, wxT("Create a new line connected with AND") }, { mgMBC_CREATENEW_ORLINE, wxT("Create a new line connected with OR") }, { mgMBC_SIMPLEEND, wxT("") }, { mgMBC_EMBED_NUMFRACTION, wxT("Embed as num of a fraction") }, { mgMBC_EMBED_DENFRACTION, wxT("Embed as den of a fraction") }, { mgMBC_EMBED_RADICAL, wxT("Embed into a radical") }, { mgMBC_EMBED_BRACKET, wxT("Bracketize") }, { mgMBC_ADVEND, wxT("") }, { mgMBC_LAST, wxT("") } }
The list of the commands (ID+description) shown in the context menu.
These commands are usually called also from menus or toolbars, and this variable can be very useful in this case to synchronize toolbar & menu items' descriptions with the context menu items.

bool mgMathBox::m_bInputEnabled [protected]

If FALSE, this window will refuse any keyboard input and the caret will not be displayed.
Otherwise, normal input behaviour is used.

Referenced by UpdateCaret().

wxRect mgMathBox::m_rcSelection [protected]

The last selection rectangle.
This value is affected mainly by: 1) the m_bInputEnabled variable which forces the window to the standard cursor instead of the IBEAM one 2) the selection system status: when dragging a selection rectangle, the cursor is changed to the standard one.
