Detailed Description
Size Control: interactive control of the size of a widget.
when dragged interactivelly, a handle widget (typically a button) having this attribute changes the USize of another widget (typically a palette) that contains this handle.
Member Function Documentation
§ removingFrom()
called when this object is removed from a parent (SEE DETAILS IF YOU REDEFINE THIS METHOD).
!BEWARE: subclasses that redefine removingFrom() MUST HAVE A DESTRUCTOR that calls destructs().
DETAILS: this is because of a C++ subtletly: as polymorphism is deactivated in destructors, a redefined removingFrom() method won't be called except if destructs() - that calls removingFrom() - is called in the destructor of the class that redefines removingFrom()).
Reimplemented from ubit::UNode.
The documentation for this class was generated from the following files:
- src/ubit/uboxgeom.hpp
- src/ubit/uboxgeom.cpp
