这是我的问题,我想将qtvirtual键盘用于触摸屏应用程序。当我调用它时,它会在另一个窗口中弹出。如何使键盘在同一窗口上弹出?
如果我尝试使用QQuick视图和QqmlApplicationEngine(后者甚至无法加载键盘)。
答案 0 :(得分:1)
通常为detected automatically,但是如果您使用的是台式机,则可以选择“桌面集成”。
This page举例说明了如何配置应用程序的.pro文件,以根据要在哪个平台上/针对哪个平台来选择其他QML文件:
disable-desktop|android-embedded|!isEmpty(CROSS_COMPILE)|qnx {
DEFINES += MAIN_QML=\\\"basic-b2qt.qml\\\"
} else {
DEFINES += MAIN_QML=\\\"Basic.qml\\\"
}
该示例中的basic-b2qt.qml可用于应用程序集成(即在同一窗口中显示键盘):
import QtQuick 2.0
import QtQuick.Window 2.2
import QtQuick.VirtualKeyboard 2.2
import QtQuick.VirtualKeyboard.Settings 2.2
