|
## 1. 创建Qml工程
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
|
|
|
|
|
使用QtCreator创建一个简易的Qml工程,或者使用已有的工程。
|
|
|
|
|
|
|
|
|
|
这里示例创建一个HelloTaoQuick1 工程,内容如下:
|
|
|
|
|
|
|
|
|
|
![](doc/start1.png)
|
|
|
|
|
|
|
|
|
|
pro文件包含基本的Qml工程配置
|
|
|
|
|
|
|
|
|
|
```pro
|
|
|
|
|
TEMPLATE = app
|
|
|
|
|
|
|
|
|
|
QT += gui quick qml quickcontrols2
|
|
|
|
|
|
|
|
|
|
SOURCES += main.cpp
|
|
|
|
|
|
|
|
|
|
RESOURCES += Res.qrc
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
qrc资源文件中, 仅添加main.qml
|
|
|
|
|
|
|
|
|
|
```xml
|
|
|
|
|
<RCC>
|
|
|
|
|
<qresource prefix="/">
|
|
|
|
|
<file>main.qml</file>
|
|
|
|
|
</qresource>
|
|
|
|
|
</RCC>
|
|
|
|
|
```
|
|
|
|
|
|
2021-01-09 15:15:34 +08:00
|
|
|
|
## 2. 拷贝TaoQuick核心库
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
将TaoQuick核心库文件夹拷贝过来,路径是TaoQuick项目的 src/TaoQuick
|
|
|
|
|
|
|
|
|
|
(pro文件不支持绝对路径,所以拷贝一下,使用相对路径)
|
|
|
|
|
|
|
|
|
|
![](doc/start2.png)
|
|
|
|
|
|
|
|
|
|
如图所示,HelloTaoQuick1 项目文件夹下,多了一个TaoQuick文件夹,内含 TaoQuick.pri文件和imports文件夹。
|
|
|
|
|
|
2021-01-09 15:15:34 +08:00
|
|
|
|
## 3. 导入核心库
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
在项目的pro文件中,增加一行include指令,包含相对工程路径下的TaoQuick.pri文件即可
|
|
|
|
|
|
|
|
|
|
(pro文件不支持绝对路径,使用相对路径)
|
|
|
|
|
|
|
|
|
|
```pro
|
|
|
|
|
TEMPLATE = app
|
|
|
|
|
|
|
|
|
|
QT += gui quick qml quickcontrols2
|
|
|
|
|
|
|
|
|
|
SOURCES += main.cpp
|
|
|
|
|
|
|
|
|
|
RESOURCES += Res.qrc
|
|
|
|
|
|
|
|
|
|
include(TaoQuick/TaoQuick.pri)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
此pri文件提供了两个宏定义:
|
|
|
|
|
|
|
|
|
|
TaoQuickImportPath 指向TaoQuick核心库的qmldir文件所在路径,
|
|
|
|
|
|
|
|
|
|
需要将此路径添加到Qml引擎导入路径中(添加方法在下一步),Qml才能识别TaoQuick库;
|
|
|
|
|
|
|
|
|
|
TaoQuickImagePath 指向TaoQuick核心库的图片资源路径。
|
|
|
|
|
|
2021-01-09 15:15:34 +08:00
|
|
|
|
## 4. 增加导入路径

|
|
### 4.1 两种不同Qml工程的说明
|
2020-11-22 00:55:53 +08:00
|
|
|
|
对于一般的Qml工程,最简单的main.cpp内容,可以有两种使用方式,
|
|
|
|
|
|
|
|
|
|
使用QQuickView:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
#include <QQuickView>
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
int main(int argc, char **argv)
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
QQuickView view;
|
|
|
|
|
view.setSource(QUrl("qrc:/main.qml"));
|
|
|
|
|
view.show();
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
或者使用QQmlApplicationEngine:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
#include <QQmlApplicationEngine>
|
|
|
|
|
|
|
|
|
|
int main(int argc, char *argv[])
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
|
|
|
|
|
QQmlApplicationEngine engine;
|
|
|
|
|
const QUrl url(QStringLiteral("qrc:/main.qml"));
|
|
|
|
|
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
|
|
|
|
|
&app, [url](QObject *obj, const QUrl &objUrl) {
|
|
|
|
|
if (!obj && url == objUrl)
|
|
|
|
|
QCoreApplication::exit(-1);
|
|
|
|
|
}, Qt::QueuedConnection);
|
|
|
|
|
engine.load(url);
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
两种用法本质是一样的,细微区别是:QQuickView本身就是一个主窗口,main.qml顶层元素不能再是Window或者Window的子类;QQmlEngine本身不包含主窗口,main.qml顶层元素必须是Window或者Window的子类。
|
|
|
|
|
|

|
|
|
|
### 4.2 设置路径
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
我们需要在QmlEngine加载source之前,增加importPath,并把imagePath设置为上下文。
|
|
|
|
|
|
|
|
|
|
如果主窗口是由QQuickView加载的,则:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
view.engine()->addImportPath(TaoQuickImportPath);
|
|
|
|
|
view.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如果主窗口是由QQmlEngine加载的,则:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
engine.addImportPath(TaoQuickImportPath);
|
|
|
|
|
engine.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
完整的代码如下:
|
|
|
|
|
|
|
|
|
|
QQuickView版本
|
|
|
|
|
```C++
|
|
|
|
|
#include <QQuickView>
|
|
|
|
|
#include <QQmlEngine>
|
|
|
|
|
#include <QQmlContext>
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
int main(int argc, char **argv)
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
QQuickView view;
|
|
|
|
|
|
|
|
|
|
view.engine()->addImportPath(TaoQuickImportPath);
|
|
|
|
|
view.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
//setSource 之前,要设置好路径
|
|
|
|
|
view.setSource(QUrl("qrc:/main.qml"));
|
|
|
|
|
view.show();
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
QQmlApplicationEngine版本:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
#include <QQmlApplicationEngine>
|
|
|
|
|
#include <QQmlContext>
|
|
|
|
|
int main(int argc, char *argv[])
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
|
|
|
|
|
QQmlApplicationEngine engine;
|
|
|
|
|
engine.addImportPath(TaoQuickImportPath);
|
|
|
|
|
engine.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
|
|
|
|
|
const QUrl url(QStringLiteral("qrc:/main.qml"));
|
|
|
|
|
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
|
|
|
|
|
&app, [url](QObject *obj, const QUrl &objUrl) {
|
|
|
|
|
if (!obj && url == objUrl)
|
|
|
|
|
QCoreApplication::exit(-1);
|
|
|
|
|
}, Qt::QueuedConnection);
|
|
|
|
|
|
|
|
|
|
//load 之前,设置好路径
|
|
|
|
|
engine.load(url);
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
```

|
## 5. 使用TaoQuick组件
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
一个简单的main.qml,内容如下:
|
|
|
|
|
|
|
|
|
|
QQuickView版本
|
|
|
|
|
```qml
|
|
|
|
|
import QtQml 2.0
|
|
|
|
|
import QtQuick 2.9
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Rectangle {
|
|
|
|
|
color: "lightblue"
|
|
|
|
|
width: 640
|
|
|
|
|
height: 480
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
Engine版本
|
|
|
|
|
```qml
|
|
|
|
|
import QtQuick 2.12
|
|
|
|
|
import QtQuick.Window 2.12
|
|
|
|
|
|
|
|
|
|
Window {
|
|
|
|
|
width: 640
|
|
|
|
|
height: 480
|
|
|
|
|
visible: true
|
|
|
|
|
title: qsTr("Hello World")
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
接下来增加一行import,导入TaoQuick
|
|
|
|
|
|
|
|
|
|
```qml
|
|
|
|
|
import TaoQuick 1.0
|
|
|
|
|
import QtQml 2.0
|
|
|
|
|
import QtQuick 2.9
|
|
|
|
|
|
|
|
|
|
Rectangle {
|
|
|
|
|
color: "lightblue"
|
|
|
|
|
width: 640
|
|
|
|
|
height: 480
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
导入过后,按一下Ctrl + S,保存一下。
|
|
|
|
|
|
|
|
|
|
只要路径正确,QtCreator就可以识别到TaoQuick库,可以直接使用TaoQuick库中的组件。
|
|
|
|
|
|
|
|
|
|
这里示例,使用蓝色按钮组件:
|
|
|
|
|
```qml
|
|
|
|
|
...
|
|
|
|
|
CusButton_Blue {
|
|
|
|
|
width: 120
|
|
|
|
|
height: 36
|
|
|
|
|
anchors.centerIn: parent
|
|
|
|
|
text: "Hello"
|
|
|
|
|
onClicked: {
|
|
|
|
|
console.log("hello TaoQuick")
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
...
|
|
|
|
|
```
|
|
|
|
|
TaoQuick库已经做好了QtCreator的语法高亮和Qml代码跳转
|
|
|
|
|
|
|
|
|
|
![](doc/start3.png)
|
|
|
|
|
|
|
|
|
|
当然也可以切换到Design模式,以拖拽、属性编辑的方式,创建、编辑组件
|
|
|

|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
将TaoQuick核心库文件夹拷贝过来,路径是TaoQuick项目的 src/TaoQuick
|
|
|
|
|
|
|
|
|
|
![](doc/cmake2.png)
|
|
|
|
|
|
|
|
|
|
如图所示,HelloTaoQuick2 项目文件夹下,多了一个TaoQuick文件夹,内含 TaoQuick.pri文件和imports文件夹。

|
## 3. 导入核心库
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
将TaoQuick项目路径中cmake/taoQuick.cmake文件拷贝到HelloTaoQuick2项目路径下
|
|
|
|
|
|
|
|
|
|
![](doc/cmake3.png)
|
|
|
|
|
|
|
|
|
|
将taoQuick.cmake文件中第一行,路径修改为当前路径下的TaoQuick/imports文件夹
|
|
|
|
|
|
|
|
|
|
![](doc/cmake4.png)
|
|
|
|
|
|
|
|
|
|
在项目的CMakeLists.txt文件中,导入taoQuick.cmake文件
|
|
|
|
|
|
|
|
|
|
![](doc/cmake5.png)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
在项目的add_executable指令中,增加一项TaoQuickRes
|
|
|
|
|
|
|
|
|
|
![](doc/cmake6.png)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
说明一下吧,taoQuick.cmake文件提供了两个宏定义:
|
|
|
|
|
|
|
|
|
|
TaoQuickImportPath 指向TaoQuick核心库的qmldir文件所在路径,
|
|
|
|
|
|
|
|
|
|
需要将此路径添加到Qml引擎导入路径中(添加方法在下一步),Qml才能识别TaoQuick库;
|
|
|
|
|
|
|
|
|
|
TaoQuickImagePath 指向TaoQuick核心库的图片资源路径。
|
|
|
|
|
|
|
|
|
|
TaoQuickRes 只在Release模式时,指向TaoQuick的资源文件所在路径。
|
|
|

### 4.1 两种不同Qml工程的说明
|
2020-11-22 00:55:53 +08:00
|
|
|
|
对于一般的Qml工程,最简单的main.cpp内容,可以有两种使用方式,
|
|
|
|
|
|
|
|
|
|
使用QQuickView:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
#include <QQuickView>
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
int main(int argc, char **argv)
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
QQuickView view;
|
|
|
|
|
view.setSource(QUrl("qrc:/main.qml"));
|
|
|
|
|
view.show();
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
或者使用QQmlApplicationEngine:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
#include <QQmlApplicationEngine>
|
|
|
|
|
|
|
|
|
|
int main(int argc, char *argv[])
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
|
|
|
|
|
QQmlApplicationEngine engine;
|
|
|
|
|
const QUrl url(QStringLiteral("qrc:/main.qml"));
|
|
|
|
|
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
|
|
|
|
|
&app, [url](QObject *obj, const QUrl &objUrl) {
|
|
|
|
|
if (!obj && url == objUrl)
|
|
|
|
|
QCoreApplication::exit(-1);
|
|
|
|
|
}, Qt::QueuedConnection);
|
|
|
|
|
engine.load(url);
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
两种用法本质是一样的,细微区别是:QQuickView本身就是一个主窗口,main.qml顶层元素不能再是Window或者Window的子类;QQmlEngine本身不包含主窗口,main.qml顶层元素必须是Window或者Window的子类。

|
|
|
|
### 4.2 设置路径
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
我们需要在QmlEngine加载source之前,增加importPath,并把imagePath设置为上下文。
|
|
|
|
|
|
|
|
|
|
如果主窗口是由QQuickView加载的,则:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
view.engine()->addImportPath(TaoQuickImportPath);
|
|
|
|
|
view.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如果主窗口是由QQmlEngine加载的,则:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
engine.addImportPath(TaoQuickImportPath);
|
|
|
|
|
engine.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
完整的代码如下:
|
|
|
|
|
|
|
|
|
|
QQuickView版本
|
|
|
|
|
```C++
|
|
|
|
|
#include <QQuickView>
|
|
|
|
|
#include <QQmlEngine>
|
|
|
|
|
#include <QQmlContext>
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
int main(int argc, char **argv)
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
QQuickView view;
|
|
|
|
|
|
|
|
|
|
view.engine()->addImportPath(TaoQuickImportPath);
|
|
|
|
|
view.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
//setSource 之前,要设置好路径
|
|
|
|
|
view.setSource(QUrl("qrc:/main.qml"));
|
|
|
|
|
view.show();
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
QQmlApplicationEngine版本:
|
|
|
|
|
|
|
|
|
|
```C++
|
|
|
|
|
#include <QGuiApplication>
|
|
|
|
|
#include <QQmlApplicationEngine>
|
|
|
|
|
#include <QQmlContext>
|
|
|
|
|
int main(int argc, char *argv[])
|
|
|
|
|
{
|
|
|
|
|
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
|
|
|
|
|
|
|
|
|
|
QGuiApplication app(argc, argv);
|
|
|
|
|
|
|
|
|
|
QQmlApplicationEngine engine;
|
|
|
|
|
engine.addImportPath(TaoQuickImportPath);
|
|
|
|
|
engine.rootContext()->setContextProperty("taoQuickImagePath", TaoQuickImagePath);
|
|
|
|
|
|
|
|
|
|
const QUrl url(QStringLiteral("qrc:/main.qml"));
|
|
|
|
|
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
|
|
|
|
|
&app, [url](QObject *obj, const QUrl &objUrl) {
|
|
|
|
|
if (!obj && url == objUrl)
|
|
|
|
|
QCoreApplication::exit(-1);
|
|
|
|
|
}, Qt::QueuedConnection);
|
|
|
|
|
|
|
|
|
|
//load 之前,设置好路径
|
|
|
|
|
engine.load(url);
|
|
|
|
|
|
|
|
|
|
return app.exec();
|
|
|
|
|
}
|
|
|
|
|
```

## 5. 使用TaoQuick组件
|
2020-11-22 00:55:53 +08:00
|
|
|
|
|
|
|
|
|
一个简单的main.qml,内容如下:
|
|
|
|
|
|
|
|
|
|
QQuickView版本
|
|
|
|
|
```qml
|
|
|
|
|
import QtQml 2.0
|
|
|
|
|
import QtQuick 2.9
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Rectangle {
|
|
|
|
|
color: "lightblue"
|
|
|
|
|
width: 640
|
|
|
|
|
height: 480
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
Engine版本
|
|
|
|
|
```qml
|
|
|
|
|
import QtQuick 2.12
|
|
|
|
|
import QtQuick.Window 2.12
|
|
|
|
|
|
|
|
|
|
Window {
|
|
|
|
|
width: 640
|
|
|
|
|
height: 480
|
|
|
|
|
visible: true
|
|
|
|
|
title: qsTr("Hello World")
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
接下来增加一行import,导入TaoQuick
|
|
|
|
|
|
|
|
|
|
```qml
|
|
|
|
|
import TaoQuick 1.0
|
|
|
|
|
import QtQml 2.0
|
|
|
|
|
import QtQuick 2.9
|
|
|
|
|
|
|
|
|
|
Rectangle {
|
|
|
|
|
color: "lightblue"
|
|
|
|
|
width: 640
|
|
|
|
|
height: 480
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
导入过后,就可以直接使用TaoQuick库中的组件。
|
|
|
|
|
|
|
|
|
|
这里示例,使用蓝色按钮组件:
|
|
|
|
|
```qml
|
|
|
|
|
...
|
|
|
|
|
CusButton_Blue {
|
|
|
|
|
width: 120
|
|
|
|
|
height: 36
|
|
|
|
|
anchors.centerIn: parent
|
|
|
|
|
text: "Hello"
|
|
|
|
|
onClicked: {
|
|
|
|
|
console.log("hello TaoQuick")
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
...
|
|
|
|
|
```
|
|
|
|
|
|
