【Qt】QLineEdit点击调用surface触摸键盘
本文共 403 字，大约阅读时间需要 1 分钟。
surface本身有个触摸键盘，点系统的编辑框就会弹出来，和windows系统里面osk.exe不同。
ui->lineEdit->setEchoMode(QLineEdit::NoEcho);ui->lineEdit_2->setEchoMode(QLineEdit::Password);
设置这两个属性都可以调起触摸键盘。这也是无意中发现的，因为所做的软件有账号密码登录，密码框设置了Password的属性，能自动弹起来，账号框不行，就去看了QLineEdit的源码，想看是怎么调起来的。下面看源码：
看焦点获取事件，
if (d->control->echoMode() == Password || d->control->echoMode() == NoEcho)
这个判断下面应该就是调起键盘的，网上没搜到qt_mac_secure_keyboard这个是干嘛的，源码也没找到。后续有时间再看
