static gboolean linkEvent	(	GtkTextTag *	tag,
		GtkWidget *	w,
		GdkEventButton *	event,
		GtkTextIter *	iter,
		gpointer	d
	)			[static]

Signal handler for GTK+ link events.

Parameters:

[in]	tag	GTK+ tag of the link
[in]	w	GTK+ textview widget
[in]	event	event description
[in]	iter	location of the event in the textbuffer
[in]	d	adress of a NMEGtkLinkCB structure

void NMEGtkApplyStyle	(	NMEGtk const *	nmegtk,
		NMEStyleTable const *	spanTable,
		NMEInt	offset,
		NMEInt	length,
		NMEConstText	nmeTextForLinks
	)

Apply styles collected by NMEStyle to a GTK+ text buffer.

Parameters:

[in]	nmegtk	data structure initialized by NMEGtkInit
[in]	spanTable	table of style spans created by NMEProcess with NMEStyle
[in]	offset	offset of NME output in textBuffer, in unicode characters
[in]	length	length of NME output in unicode characters
[in]	nmeTextForLinks	set hypertext links if source NME text, don't if NULL

Definition at line 129 of file NMEGtk.c.

void NMEGtkInit	(	NMEGtk *	nmegtk,
		GtkTextBuffer *	textBuffer,
		int	charSize
	)

Initialize NMEGtk data structure.

Parameters:

[out]	nmegtk	data structure used by NMEGtkApplyStyle
[in]	textBuffer	text buffer style is applied to
[in]	charSize	standard text character size, used as the basis for heading sizes and superscript/subscript offsets

NMEErr NMEGtkInsert	(	GtkTextBuffer *	textBuffer,
		NMEGtk const *	nmegtk,
		NMEConstText	str,
		NMEInt	len,
		NMEBoolean	replaceSel,
		NMEBoolean	links
	)

Insert text with NME markup in a GtkTextBuffer, calling NMEGtkApplyStyle.

Parameters:

[in,out]	textBuffer	GTK+ text buffer
[in]	nmegtk	NMEGtk structure for textBuffer, initialized with NMEGtkInit
[in]	str	text with NME markup
[in]	len	length of str in bytes, or -1 if str is null-terminated
[in]	replaceSel	if TRUE, replace selection, else replace whole text
[in]	links	set hypertext links if TRUE

void NMEGtkSetLinkFun	(	NMEGtk *	nmegtk,
		NMEGtkLinkFun	linkFun,
		void *	linkFunData
	)

Set the callback which processes clicks on links.

Parameters:

[in,out]	nmegtk	data structure used by NMEGtkApplyStyle
[in]	linkFun	callback which handles link clicks
[in]	linkFunData	value passed to linkFun
