Frequently used methods are thus easier to access. By clicking the button, these are executed. ..

GENERATED FROM PYTHON SOURCE LINES 49-51 Add a single button without icon to a new toolbar with the name ``demobar``. The callback function is the unbounded method ``method`` without arguments. ..

GENERATED FROM PYTHON SOURCE LINES 54-57 This is quite similar than the addButton above, however internally it makes a difference if a Python-scripted method is used as callback or a method from the itom module, implemented in C. ..
