TType  type,
bool  withShift 
)

Member Function Documentation

bool TransformTool::isValid ( ) const

Check that the transformation can be performed.

References iValid.

void TransformTool::draw ( Painter painter) const
virtual
void TransformTool::mouseButton ( int  button,
bool  press 
)
virtual

Called when a mouse button is pressed or released on the canvas.

button is 1, 2, or 3, with Shift/Ctrl/Alt/Meta modifiers added in (as defined in CanvasBase::TModifiers. press is true for button-down, and false for button-up.

Reimplemented from ipe::Tool.

References compute(), ipe::CanvasBase::finishTool(), ipe::Tool::iCanvas, ipe::CanvasBase::pos(), and report().

void TransformTool::mouseMove ( )
virtual

Called when the mouse is moved on the canvas.

Reimplemented from ipe::Tool.

References compute(), ipe::Tool::iCanvas, ipe::CanvasBase::pos(), and ipe::CanvasBase::updateTool().

void TransformTool::report ( )
virtual

Report the final transformation chosen.

The implementation in TransformTool does nothing. Derived classes should reimplement report().
