Member Function Documentation

childCount()

int QgsHistoryEntryNode::childCount ( ) const

virtual

Returns the number of child nodes owned by this node.

Reimplemented in QgsHistoryEntryGroup.

Definition at line 24 of file qgshistoryentrynode.cpp.

createWidget()

QWidget * QgsHistoryEntryNode::createWidget ( const QgsHistoryWidgetContext &  context )

virtual

Returns a new widget which should be shown to users when selecting the node.

If a nullptr is returned, the node's html() method will be called instead to create the node's content.

html()

Definition at line 34 of file qgshistoryentrynode.cpp.

data()

virtual QVariant QgsHistoryEntryNode::data ( int  role = Qt::DisplayRole ) const

pure virtual

Returns the node's data for the specified model role.

doubleClicked()

bool QgsHistoryEntryNode::doubleClicked ( const QgsHistoryWidgetContext &  context )

virtual

Called when the node is double-clicked.

The default implementation does nothing.

Returns true if the node handled the double-click event and it should not be further processed.

Definition at line 39 of file qgshistoryentrynode.cpp.

html()

QString QgsHistoryEntryNode::html ( const QgsHistoryWidgetContext &  context ) const

virtual

Returns a HTML formatted text string which should be shown to a user when selecting the node.

Subclasses should implement this method or createWidget(), but not both.

See also

createWidget()

Definition at line 29 of file qgshistoryentrynode.cpp.

matchesString()

bool QgsHistoryEntryNode::matchesString ( const QString &  searchString ) const

virtual

Returns true if the node matches the specified searchString, and should be shown in filtered results with that search string.

The default implementation returns true if the string is contained within the node's DisplayRole.

Definition at line 49 of file qgshistoryentrynode.cpp.

operator=()

QgsHistoryEntryNode & QgsHistoryEntryNode::operator= ( const QgsHistoryEntryNode &  other )

delete

QgsHistoryEntryNode cannot be copied.

parent()

QgsHistoryEntryGroup * QgsHistoryEntryNode::parent ( )

inline

Returns the node's parent node.

If parent is nullptr, the node is a root node.

Definition at line 59 of file qgshistoryentrynode.h.

populateContextMenu()

void QgsHistoryEntryNode::populateContextMenu ( QMenu *  menu, const QgsHistoryWidgetContext &  context  )

virtual

Allows the node to populate a context menu before display to the user.

Actions should be parented to the specified menu.

Definition at line 44 of file qgshistoryentrynode.cpp.
