Member Function Documentation

void CommandHistory::addCommand (  Command *  command, bool  execute = true )

Adds a command to the history. Call this for each command you create. Unless you set execute to false, this will also execute the command. This means, most of the application's code will look like MyCommand * cmd = new MyCommand(...); m_historyCommand.addCommand( cmd ); Ownership of command is transfered to CommandHistory Definition at line 63 of file CommandHistory.cpp. References Command, commands, DEBUG_FATAL, AppBase::Command< StringType >::execute(), and nextCmd.

bool CommandHistory::canRedo (   )

Return true iff there is a command to redo. Definition at line 141 of file CommandHistory.cpp. References commands, and nextCmd. Referenced by PreviewFrame::OnRedo(), MainFrame::OnRedo(), and MainFrame::panoramaChanged().

bool CommandHistory::canUndo (   )

Return true iff there is a command to undo. Definition at line 136 of file CommandHistory.cpp. References nextCmd. Referenced by PreviewFrame::OnUndo(), MainFrame::OnUndo(), and MainFrame::panoramaChanged().

void CommandHistory::clear (   )

void CommandHistory::redo (   )  [virtual]

Redoes the last undone action. Definition at line 116 of file CommandHistory.cpp. References commands, DEBUG_DEBUG, DEBUG_ERROR, AppBase::Command< StringType >::execute(), HUGIN_SMART_UNDO, and nextCmd. Referenced by MainFrame::OnRedo().

void CommandHistory::undo (   )  [virtual]
