Message definition (Development/Tutorials/KDE3/Qt Designer and KDevelop 3.0 for Beginners)

A few more words about signals and slots. The signals and slots mechanism is type safe: the signature of a signal must match the signature of the receiving slot (for example, you will connect valueChanged(int) with a slot having an int as argument). And another thing to keep in mind is that all classes that inherit from QObject or one of its subclasses (e.g. QWidget) can contain signals and slots.

signal/slot についてもう少しだけ説明しておきます。 signal/slot 機構は型について厳格です。 signal の型は slot の型に一致しなければなりません。 (例えば valueChanged(int) というシグナルはintを引数にとるスロットにしか接続できません) またもう一つ覚えておかなければならないことは、QObject を継承しているクラスだけが signal と slot を持つことができるという点です。
