Detailed Description

The FileField class.

An EffectField derivative that produces filenames in string and uses an EmbeddedFileChooser as its visual representation.

Constructor & Destructor Documentation

FileField::FileField ( EffectRow parent,
const QString &  id 
)

Reimplementation of EffectField::EffectField().

Member Function Documentation

QWidget * FileField::CreateWidget ( QWidget *  existing = nullptr)
overridevirtual

Reimplementation of EffectField::CreateWidget()

Creates and connects to a EmbeddedFileChooser.

Implements EffectField.

QString FileField::GetFileAt ( double  timecode)

Get the filename at the given timecode.

A convenience function, equivalent to GetValueAt(timecode).toString()

Parameters
timecodeThe timecode to retrieve the filename at
Returns

The filename at this timecode

void FileField::UpdateFromWidget ( const QString &  s)
privateslot

Internal function connected to any QWidget made from CreateWidget() to update the value based on user input.

Parameters
bThe current string of the QWidget (TextEditEx in this case). Automatically set when this slot is connected to the TextEditEx::textModified() signal.
void FileField::UpdateWidgetValue ( QWidget *  widget,
double  timecode 
)
overridevirtual

Reimplementation of EffectField::UpdateWidgetValue()

Reimplemented from EffectField.
