Member Function Documentation

bool KLFLatexEdit::canInsertFromMimeData ( const QMimeData * source ) const [protected, virtual]

Definition at line 314 of file klflatexedit.cpp.

References QMimeData::formats(), and klfDbg.

void KLFLatexEdit::clearLatex ( ) [slot]

Definition at line 243 of file klflatexedit.cpp.

References setLatex().

void KLFLatexEdit::contextMenuEvent ( QContextMenuEvent * event ) [protected, virtual]

Definition at line 287 of file klflatexedit.cpp.

References insertContextMenuActions(), and QList::size().

int KLFLatexEdit::heightHintLines ( ) const

See sizeHint(). This gets the preferred height of this widget in number of text lines, as set by setHeightHintLints().

void KLFLatexEdit::insertContextMenuActions	(	const QPoint &	pos,
		QList< QAction * > *	actionList
	)		`[signal]`

This signal is emitted just before the context menu is shown. If someone wants to add entries into the context menu, then connect to this signal, and append new actions to the actionList.

Referenced by contextMenuEvent().

void KLFLatexEdit::insertDelimiter	(	const QString &	delim,
		int	charsBack = `1`
	)		`[slot]`

Inserts a delimiter delim, and brings the cursor charsBack characters back. Eg. you can insert "\mathrm{}" and bring the cursor 1 space back.

void KLFLatexEdit::insertFromMimeData ( const QMimeData * source ) [protected, virtual]

Definition at line 325 of file klflatexedit.cpp.

References QMimeData::formats(), klfDbg, KLFDropDataHandler::OpenDataFailed, and KLFDropDataHandler::OpenDataOk.

QString KLFLatexEdit::latex ( ) const

Definition at line 226 of file klflatexedit.cpp.

void KLFLatexEdit::setDropDataHandler ( KLFDropDataHandler * handler )

This function may be used to give a pointer to a KLFDropDataHandler that we will call to open data when we get a paste/drop. If they can open the data, then we consider the data pasted. Otherwise, rely on the QTextEdit built-in functionality.

This pointer may also be NULL, in which case we will only rely on QTextEdit built-in functionality.

Definition at line 234 of file klflatexedit.cpp.

void KLFLatexEdit::setHeightHintLines ( int lines ) [slot]

See sizeHint(). This sets the preferred height of this widget in number of text lines.

Definition at line 280 of file klflatexedit.cpp.

void KLFLatexEdit::setLatex ( const QString & latex ) [slot]

Sets the current latex code to latex.

Note:: this function, unlike QTextEdit::setPlainText(), preserves undo history.

References QTextCursor::beginEditBlock(), QTextCursor::endEditBlock(), QTextCursor::insertText(), QTextCursor::removeSelectedText(), and QTextCursor::select().

void KLFLatexEdit::setPalette ( const QPalette & palette ) [slot]

Directly calls the superclass' method. This is just used so that we have a slot.

Definition at line 365 of file klflatexedit.cpp.

void KLFLatexEdit::setWrapLines ( bool wrap ) [slot]

Set to TRUE to wrap lines, false to have a horizontal scroll. This directly calls QTextEdit::setWordWrapMode() with either QTextOption::NoWrap (FALSE) or QTextOption::WrapAnywhere.

Definition at line 265 of file klflatexedit.cpp.

QSize KLFLatexEdit::sizeHint ( ) const [virtual]

The size hint of the widget. If heightHintLines() is set to -1, this directly calles the superclass function. Otherwise this returns the size in pixels this widget wants to have, given the value of heightHintLines() number of lines in the current font.
