int KLFLatexEdit::heightHintLines | ( | ) | const [inline] |
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
.

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::setMainWinDataOpener | ( | KLFMainWin * | mainwin | ) | [inline] |
This function may be used to give a pointer to a KLFMainWin 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.

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.
