if( screen )
{
// returns a human readable value which can be displayed as zoom
// level indicator in dialogs.
double level = m_zoomLevelCoeff / (double)screen->GetZoom();
Line.Printf( wxT( "Z %.2f" ), level );
}

}示例2: update
void ZOOM_MENU::update()
{
BASE_SCREEN* screen = m_parent->GetScreen();
double zoom = screen->GetZoom();
const std::vector<double>& zoomList = m_parent->GetScreen()->m_ZoomList;
// Check the current zoom

}示例3: UpdateStatusBar

// Absolute and relative cursor positions are handled by overloading this function and
// handling the internal to user units conversion at the appropriate level.
