+# 数字软键盘
+
+## qmake作为pri使用
+
+- 将文件夹复制到主工程Libs目录下
+- 主工程pro文件中加入：
+
+```qmake
+include($$PWD/Libs/SoftNumKeyBoard/NumKeyBoard.pri)
+```
+
+- 主工程中重写eventFilter函数，实现点击lineedit时，调出小键盘
+
+```cpp
+protected:
+    virtual bool eventFilter(QObject * obj, QEvent *event) override;
+```
+
+```cpp
+bool SettingWidget::eventFilter(QObject *obj, QEvent * event)
+{
+    auto _obj = static_cast<QLineEdit *>(obj);
+    if(m_inputList.contains(_obj))
+    {
+        if(event->type() == QEvent::FocusIn)
+        {
+            if(!_keyBoard)
+            {
+                _keyBoard = new NumKeyDia(this);
+            }
+            //传入对应的QLineEdit
+            _keyBoard->setPLineEdit(_obj);
+            _keyBoard->exec();
+            //QLineEdit取消聚焦，可以不用
+            _obj->clearFocus();
+            return true;
+        }
+    }
+    return QObject::eventFilter(obj, event);
+}
+```
+
+- 对应的控件安装事件过滤器
+
+```cpp
+    m_inputList = this->findChildren<QLineEdit *>();
+    foreach (auto &i, m_inputList)
+    {
+        i->installEventFilter(this);
+        i->setFocusPolicy(Qt::ClickFocus);
+    }
+```
+
+- 控件设置属性
+
+```cpp
+    //设置输入输出的最大值、最小值、名字和是否是数字
+    ui->lineEdit_energyA->setProperty("IsNum", true);
+	//double时，默认保留三位小数
+    ui->lineEdit_energyA->setProperty("IsDouble", true);
+    //输入的数不能超过最大值和最小值
+	 ui->lineEdit_energyA->setProperty("Max", 1.000);
+    ui->lineEdit_energyA->setProperty("Min", 0.000);
+    ui->lineEdit_energyA->setProperty("Name", tr("PressureA"));
+```
