QML 在Mac OS X上运行问题
-
本人在开发机上新建QML工程，编译打包成dmg后，在本机可直接点击安装运行。在没有安装Qt环境的目标机上，程序可点击运行，但是程序界面不显示，且程序处于未响应状态。
开发环境为：High Sierra 10.13.6 Qt 5.11.3 + Clang 64bit
目标环境为：Big Sur 11.4
qml代码：
import QtQuick 2.6 import QtQuick.Window 2.2 import QtQuick.Controls 1.6 Window { width: 640 height: 480 visible: true title: qsTr("Hello World") Button { x: 300 y: 220 text: qsTr("Click") } }插件加载日志：
