## qmake 使用TaoQuick
|
||||
|
||||
### 1. 创建Qml工程
|
||||
|
||||
|
||||
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>
|
||||
```
|
||||
|
||||
### 2. 拷贝TaoQuick核心库
|
||||
|
||||
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。
|
||||
|
||||
### 3. 导入核心库
|
||||
|
||||
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。
|
||||
|
||||
### 4. 增加导入路径
|
||||
|
||||
#### 4.1 两种不同Qml工程的说明
|
||||
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
|
||||
|
||||
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
|
||||
|
||||
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
|
||||
|
||||
![](doc/start4.png)
|
||||
|
||||
### 6. 运行效果
|
||||
|
||||
最后,运行起来看看效果吧
|
||||
|
||||
![](doc/start5.png)
|
||||
|
||||
## cmake 使用TaoQuick
|
||||
|
||||
### 1.创建工程
|
||||
|
||||
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HelloTaoQuick2 工程,内容如下:
|
||||
|
||||
![](doc/cmake1.png)
|
||||
|
||||
其中工程文件,CMakeLists.txt内容如下:
|
||||
|
||||
```cmake
|
||||
cmake_minimum_required(VERSION 3.14)
|
||||
|
||||
project(HelloTaoQuick2 LANGUAGES CXX)
|
||||
|
||||
set(CMAKE_INCLUDE_CURRENT_DIR ON)
|
||||
|
||||
set(CMAKE_AUTOUIC ON)
|
||||
set(CMAKE_AUTOMOC ON)
|
||||
set(CMAKE_AUTORCC ON)
|
||||
|
||||
set(CMAKE_CXX_STANDARD 11)
|
||||
set(CMAKE_CXX_STANDARD_REQUIRED ON)
|
||||
|
||||
find_package(QT NAMES Qt6 Qt5 COMPONENTS Core Quick REQUIRED)
|
||||
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Core Quick REQUIRED)
|
||||
|
||||
if(ANDROID)
|
||||
add_library(HelloTaoQuick2 SHARED
|
||||
main.cpp
|
||||
qml.qrc
|
||||
)
|
||||
else()
|
||||
add_executable(HelloTaoQuick2
|
||||
main.cpp
|
||||
qml.qrc
|
||||
)
|
||||
endif()
|
||||
|
||||
target_compile_definitions(HelloTaoQuick2
|
||||
PRIVATE $<$<OR:$<CONFIG:Debug>,$<CONFIG:RelWithDebInfo>>:QT_QML_DEBUG>)
|
||||
target_link_libraries(HelloTaoQuick2
|
||||
PRIVATE Qt${QT_VERSION_MAJOR}::Core Qt${QT_VERSION_MAJOR}::Quick)
|
||||
|
||||
```
|
||||
|
||||
### 2. 拷贝TaoQuick核心库
|
||||
|
||||
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
|
||||
|
||||
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. 增加导入路径
|
||||
|
||||
#### 4.1 两种不同Qml工程的说明
|
||||
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
|
||||
|
||||
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
|
||||
|
||||
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")
|
||||
}
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
