Qt 信号-槽函数（signal - slot）

新建一个form1窗体后，ui中拖入控件lineEdit，radioButton、radioButton_2、QGroupBox，
radioButton、radioButton_2放在QGroupBox上面，因为此时会在radioButton之间有一个聚焦，

form1.h

public slots:
	void ontext1Changed( QWidget* pSource);
	void onedit1GotFocus( QWidget* pSource);
	void onkeyUp1( int nKey, int nButtonState, bool& rbIgnoreEvent, QWidget* pSource);
	
	void onradioButton1Sel( QWidget* pSource);
	void onradioButton2Sel( QWidget* pSource);
	void onkeyUpRadio1( int nKey, int nButtonState, bool& rbIgnoreEvent, QWidget* pSource);
	void onkeyUpRadio2( int nKey, int nButtonState, bool& rbIgnoreEvent, QWidget* pSource);
