C++之Qt组合键Insert+Space实现

                                                    C++之Qt组合键Insert+Space实现

          在Qt C++编程中，使用Insert+Space插入全角空格，经常会出现被输入法拦截的情况，以下代码可解决这个问题，大家可以借鉴一下。

bool CFindReplaceDlg::eventFilter(QObject *obj, QEvent * event)
{
	static bool bPressInsert(false);
	QComboBox* pCurActiveCombo = dynamic_cast<QComboBox*>(obj);
	bool bSuccess(false);
	if(event->type() == QEvent::KeyPress)
	{
		QKeyEvent* kEvent = static_cast<QKeyEvent*>(event);
		if(kEvent->key() == Qt::Key_Return || kEvent->key() == Qt::Key_Enter){
			on_findNextPushButton_clicked();
		}else if(pCurActiveCombo && (kEvent->key() == Qt::Key_Insert)){
			bPressInsert = true;
		}else if(bPressInsert && (kEvent->key() == Qt::Key_Space)){
			bSuccess = true;
		}
	}else if(bPressInsert && (event->type() == QEvent::InputMethod)){
		bSuccess = true;
	}
	if(bSuccess){
		if(pCurActiveCombo == ui->findComboBox){
			m_strSelectText = InsertCharacterInCombo(ui->findComboBox).toStdString();
		}else if(pCurActiveCombo == ui->replaceComboBox){
			InsertCharacterInCombo(ui->replaceComboBox);
		}
		bPressInsert = false;
		return true;
	}
    return QDialog::eventFilter(obj, event);
}
