示例1: onMagnify
void WX_VIEW_CONTROLS::onMagnify( wxMouseEvent& aEvent )
{
// Scale based on the magnification from our underlying magnification event.
VECTOR2D anchor = m_view->ToWorld( VECTOR2D( aEvent.GetX(), aEvent.GetY() ) );
m_view->SetScale( m_view->GetScale() * ( aEvent.GetMagnification() + 1.0f ), anchor );
aEvent.Skip();
}示例2: DisplayStatus
void EDA_3D_CANVAS::OnMagnify( wxMouseEvent& event )
{
double magnification = ( event.GetMagnification() + 1.0f );
GetPrm3DVisu().m_Zoom /= magnification;
if( GetPrm3DVisu().m_Zoom <= 0.01 )
GetPrm3DVisu().m_Zoom = 0.01;
DisplayStatus();
Refresh( false );
}示例3: OnMagnify
void EDA_DRAW_PANEL::OnMagnify( wxMouseEvent& event )
{
// Scale the panel around our cursor position.
bool warpCursor = false;
wxPoint cursorPosition = GetParent()->GetCursorPosition( false );
wxPoint centerPosition = GetParent()->GetScrollCenterPosition();
wxPoint vector = centerPosition - cursorPosition;
double magnification = ( event.GetMagnification() + 1.0f );
double scaleFactor = GetZoom() / magnification;
// Scale the vector between the cursor and center point
vector.x /= magnification;
vector.y /= magnification;
SetZoom(scaleFactor);
// Recenter the window along our scaled vector such that the
// cursor becomes our scale axis, remaining fixed on screen
GetParent()->RedrawScreen( cursorPosition + vector, warpCursor );
event.Skip();
