Detailed Description

Mark extension interface for the Document.

Introduction

The MarkInterface provides methods to enable and disable marks in a Document, a marked line can be visualized for example with a shaded background color and/or a pixmap in the iconborder of the Document's View. There are a number of predefined mark types, specified in reservedMarkersCount(). Additionally it is possible to add custom marks and set custom pixmaps.

Accessing the Interface

The MarkInterface is supposed to be an extension interface for a Document, i.e. the Document inherits the interface provided that the KTextEditor library in use implements the interface. Use qobject_cast to access the interface:

// doc is of type KTextEditor::Document*
KTextEditor::MarkInterface *iface =
qobject_cast<KTextEditor::MarkInterface*>( doc );
if( iface ) {
// the implementation supports the interface
// do stuff
}

Handling Marks

Get all marks in the document by calling marks(). Use clearMarks() to remove all marks in the entire document. A single mark can be retrieved with mark(). To remove all marks from a line call clearMark(). To add and remove marks from a given line use addMark() and removeMark(). It is also possible to replace all marks with setMark(), i.e. setMark() is the same as a call of clearMark() followed by addMark(). The signals marksChanged() and markChanged() are emitted whenever a line's marks changed.

Attention:
A mark type is represented as an uint. An uint can have several mark types combined (see above: logical OR). That means for all functions/signals with an uint parameter, e.g. setMark(), removeMark(), etc, the uint may contain multiple marks, i.e. you can add and remove multiple marks simultaneously.

User Defined Marks

All marks that should be editable by the user can be specified with a mark mask via setEditableMarks(). To set a description and pixmap of a mark type call setMarkDescription() and setMarkPixmap().

Member Function Documentation

virtual void KTextEditor::MarkInterface::addMark ( int  line,
uint  markType 
)
pure virtual

Add marks of type markType to line.

Existing marks on this line are preserved. If the mark markType already is set, nothing happens.

Parameters:
lineline to set the mark
markTypemark type
See also:
removeMark(), setMark()
virtual void KTextEditor::MarkInterface::clearMark ( int  line)
pure virtual

Clear all marks set in the line.

Parameters:
lineline to clear marks
See also:
clearMarks(), removeMark(), addMark()
virtual void KTextEditor::MarkInterface::clearMarks ( )
pure virtual

Clear all marks in the entire document.

See also:
clearMark(), removeMark() TODO: dominik: add argument unit mask = 0
virtual uint KTextEditor::MarkInterface::editableMarks ( ) const
pure virtual

Get, which marks can be toggled by the user.

The returned value is a mark mask containing all editable marks combined with a logical OR.

Returns:
mark mask containing all editable marks
See also:
setEditableMarks()
virtual uint KTextEditor::MarkInterface::mark ( int  line)
pure virtual

Get all marks set on the line.

Parameters:
linerequested line
Returns:
a uint representing of the marks set in line concatenated by logical OR
See also:
addMark(), removeMark()
virtual void KTextEditor::MarkInterface::markChanged ( KTextEditor::Document *  document,
KTextEditor::Mark  mark,
KTextEditor::MarkInterface::MarkChangeAction  action 
)
pure virtual

The document emits this signal whenever the mark changes.

Parameters:
documentthe document which emitted the signal
markchanged mark
actionaction, either removed or added
See also:
marksChanged()
void KTextEditor::MarkInterface::markClicked ( KTextEditor::Document *  document,
KTextEditor::Mark  mark,
bool &  handled 
)
signal

The document emits this signal whenever the mark is left-clicked.

Parameters:
documentthe document which emitted the signal
markmark that was right-clicked
posposition where the menu should be started
handledset this to 'true' if this event was handled externally, and kate should not do own handling of the left click.
void KTextEditor::MarkInterface::markContextMenuRequested ( KTextEditor::Document *  document,
KTextEditor::Mark  mark,
QPoint  pos,
bool &  handled 
)
signal

The document emits this signal whenever the mark is right-clicked to show a context menu.

The receiver may show an own context menu instead of the kate internal one.

Parameters:
documentthe document which emitted the signal
markmark that was right-clicked
posposition where the menu should be started
handledset this to 'true' if this event was handled externally, and kate should not create an own context menu.
virtual QString KTextEditor::MarkInterface::markDescription ( MarkTypes  mark) const

virtual void KTextEditor::MarkInterface::setEditableMarks ( uint  markMask)
pure virtual

Set the mark mask the user is allowed to toggle to markMask.

I.e. concatenate all editable marks with a logical OR. If the user should be able to add a bookmark and set a breakpoint with the context menu in the icon pane, you have to call

// iface is of Type KTextEditor::MarkInterface*
// only make bookmark and breakpoint editable
iface->setEditableMarks( MarkInterface::Bookmark |
MarkInterface::BreakpointActive );
// or preserve last settings, and add bookmark and breakpoint
iface->setEditableMarks( iface->editableMarks() |
MarkInterface::Bookmark |
MarkInterface::BreakpointActive );
Parameters:
markMaskbitmap pattern

clearMark(line);
addMark(line, markType);
Parameters:
lineline to set the mark
markTypemark type
See also:
clearMark(), addMark(), mark()
