# 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"));
|
||
|
```
