Detailed Description
A QLThemeLineageModel is a QAbstractTableModel that implements a table model for LThemeLineageData data.
Member Function Documentation
QLThemeLineageModel(QObject* parent = nullptr)
Constructs a theme lineage model.
void append(const LThemeLineageData& lineage_data)
Adds lineage_data to the list of lineage data that the model represents.
void clear()
Clears the model data.
int columnCount(const QModelIndex& parent = QModelIndex()) const
Virtual
Override
Returns 2 since theme lineage data is sorted into 2 columns.
QVariant data(const QModelIndex& index, int role) const
Virtual
Override
Returns a QVariant containing data for the specified index.
The type of data returned depends on the specified Qt::ItemDataRole role. The following table describes the available roles and the data returned:
| Role | QVariant Data |
|---|---|
| Qt::DisplayRole || Qt::EditRole | Column 0: QString name and UUID of LThemeLineageData specified by index |
| Qt::DecorationRole | Column 1: Bool value determining whether LThemeLineageData specified by index has an implementation file available for the current application. |
QVariant headerData(int section, Qt::Orientation orientation, int role) const
Virtual
Override
Returns a QVariant containing the header for the specified section.
There is only header data for the horizontal orientation, so be sure to use Qt::Horizontal as your argument for orientation.
The following table contains the available header values:
| Section (Column) | QVariant Data |
|---|---|
| 0 | QString containing "Theme". |
| 1 | QString containing "Compatible". |
int rowCount(const QModelIndex& parent = QModelIndex()) const
Virtual
Override
Returns the number of rows under the given parent. When the parent is valid it means that rowCount() is returning the number of children of parent.
