Member Function Documentation

accelKey()

static int GLViewer_ViewTransformer::accelKey ( )

inlinestatic

Sets/returns acceleration key ( CTRL by default )

drawRect()

void GLViewer_ViewTransformer::drawRect ( const QRect &  theRect )

protected

Draws rectangle by starting and current points

References GLViewer_Viewer::getActiveView(), GLViewer_ViewFrame::getViewPort(), myRectBand, myViewer, and Plot2d::Rectangle.

endDrawRect()

void GLViewer_ViewTransformer::endDrawRect ( )

protected

Delete rubber band on the end on the dragging operation.

References myRectBand.

eventFilter()

bool GLViewer_ViewTransformer::eventFilter ( QObject *  o, QEvent *  e  )

virtual

Catches mouse events for the viewport. [ virtual protected ]

References Debut, EnTrain, Fin, myButtonState, myCurr, myMajorBtn, myStart, and onTransform().

exec()

void GLViewer_ViewTransformer::exec ( )

virtual

Runs transfomation. Redefine to add your own 'instant' transforms ( for ex., 'FitAll' is an instant transform ). [ virtual public ]

Reimplemented in GLViewer_View2dTransformer.

fitRectButton()

static int GLViewer_ViewTransformer::fitRectButton ( )

inlinestatic

Sets/returns mouse button used for fit area ( MB1 by default )

initTransform()

void GLViewer_ViewTransformer::initTransform ( bool  init )

protected

Inits long transformations ( Zoom, Pan etc ) [ protected ]

Saves viewport state( cursor etc ) and installs event filter to process mouse events if 'init' is true. Restores viewport state if 'init' is false.

References GLViewer_Viewer::getActiveView(), GLViewer_ViewFrame::getViewPort(), mySavedCursor, mySavedMouseTrack, and myViewer.

onTransform()

void GLViewer_ViewTransformer::onTransform ( TransformState  state )

protectedvirtual

Transforms the viewport. Used for 'non-instant' transforms only( ex. Rotate, Pan etc ). [ virtual protected ]

Reimplemented in GLViewer_View2dTransformer.
