Detailed Description

Shows line numbers next to a CodeEditor.

The LineNumberArea is a widget next to its associated CodeEditor widget that shows the line numbers for the content of this CodeEditor. This widget provides an area where these line numbers can be entered and stores information about the size of the line number area. However, it is the responsibility of the CodeEditor to insert the correct line numbers in the area, after the widget calls CodeEditor::lineNumberAreaPaintEvent in its paint event.

Definition at line 44 of file line_number_area.h.

Constructor & Destructor Documentation

◆ LineNumberArea()

hal::LineNumberArea::LineNumberArea ( CodeEditor * editor )

explicit

Constructor.

Parameters

editor - The CodeEditor this line number area should be associated with. Must not be a nullptr.

Definition at line 9 of file line_number_area.cpp.

References repolish().

◆ leftOffset()

int hal::LineNumberArea::leftOffset ( ) const

Definition at line 14 of file line_number_area.cpp.

◆ paintEvent()

void hal::LineNumberArea::paintEvent ( QPaintEvent * event )

overrideprotectedvirtual

Paints the line number are widget. Afterwards it invokes CodeEditor::lineNumberAreaPaintEvent so that the line numbers are inserted

Parameters

event - The paint event

Reimplemented from QWidget.
