Member Function Documentation

◆ operator=()

CmdRemoveSelectedSymbolItems& operator= ( const CmdRemoveSelectedSymbolItems rhs)

◆ performExecute()

bool performExecute ( )

Execute the command the first time.

This method must be implemented in all derived classes. If the first time execution is exactly identical to an "redo" action, you can simple call librepcb::editor::UndoCommand::performRedo() in the implementation of this method.
Return values
trueIf the command has done some changes
falseIf the command has done nothing (the command can be deleted)

Reimplemented from UndoCommandGroup.
