Member Function Documentation

createEditor()

QWidget * DecodeAsDelegate::createEditor ( QWidget *  parent, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Create an editor widget for the cell at index.

Returns a QComboBox populated with dissector table selector values (for the selector column) or dissector handle names (for the codec column). Falls back to QStyledItemDelegate for other columns.

Parameters

parent	The parent widget for the editor.
option	Style options for the editor's viewport rect.
index	The model index of the cell being edited.

Returns

The editor widget; ownership is transferred to the view.

destroyEditor()

void DecodeAsDelegate::destroyEditor ( QWidget *  editor, const QModelIndex &  index  ) const

override

Destroy the editor widget created by createEditor().

Performs any cleanup required before the editor is deleted, then delegates to QStyledItemDelegate::destroyEditor().

Parameters

editor	The editor widget to destroy.
index	The model index the editor was associated with.

setEditorData()

void DecodeAsDelegate::setEditorData ( QWidget *  editor, const QModelIndex &  index  ) const

override

Populate the editor with the current model data.

Sets the current selection of the selector or dissector combo box to match the value stored at index in the model.

Parameters

editor	The editor widget returned by createEditor().
index	The model index whose data should be loaded.

setModelData()

void DecodeAsDelegate::setModelData ( QWidget *  editor, QAbstractItemModel *  model, const QModelIndex &  index  ) const

override

Write the editor's current value back to the model.

Reads the selected item from the selector or dissector combo box and stores it into model at index.

Parameters

editor	The editor widget whose value should be committed.
model	The model to update.
index	The model index to write to.
