如何在 QML 中设置离线 OSM 目录的正确路径(不使用 qrc )?
How to set proper path to offline OSM directory in QML ( not using qrc )?
我想在带有 .exe 的文件夹中包含带有图块 realTiles
的文件夹。
当然我可以添加文件夹到qrc,一切正常:
import QtQuick 2.10
import QtQuick.Window 2.11
import QtLocation 5.12
import QtPositioning 5.12
...
Map {
id: map
anchors.fill: parent
activeMapType: map.supportedMapTypes[0]
zoomLevel: 14
plugin: Plugin {
name: 'osm';
PluginParameter {
name: 'osm.mapping.offline.directory'
value: ':/realTiles/'
}
}
}
所以我将文件夹 realTiles
复制到 .exe 文件夹和 .exe 上面的文件夹。例如,我在这 2 个位置有文件夹 realTiles
:
C:/Users/tom/Desktop/app/build-OsmOffline-Desktop_Qt_5_15_1_MinGW_64_bit-Release/release/realTiles
C:/Users/tom/Desktop/app/build-OsmOffline-Desktop_Qt_5_15_1_MinGW_64_bit-Release/realTiles
我尝试使用插件参数的值:
value: 'file:///' + applicationDirPath + '/../realTiles/'
value: 'file:///realTiles/'
value: 'file:/realTiles/'
还有很多其他的。我当然可以做错。什么是真正的解决方案?
编辑:
main.qml
import QtQuick 2.10
import QtQuick.Window 2.11
import QtLocation 5.12
import QtPositioning 5.12
Window {
id: win
objectName: "window"
visible: true
width: 512
height: 512
Map {
id: map
anchors.fill: parent
activeMapType: map.supportedMapTypes[0]
plugin: Plugin {
name: 'osm';
PluginParameter {
name: 'osm.mapping.offline.directory'
//value: ':/realTiles/'
value: 'file:///' + applicationDirPath + '/../realTiles/'
}
}
}
}
main.cpp
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QStandardPaths>
#include <QQmlContext>
int main(int argc, char *argv[])
{
QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.rootContext()->setContextProperty("applicationDirPath", QGuiApplication::applicationDirPath());
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
return app.exec();
}
尽量给出完整路径
PluginParameter {
name: "osm.mapping.cache.directory"
value: "C:/Users/UserName/Desktop/OSMCache"
}
我试过更改它起作用的缓存目录。因此请在值字段中提供完整路径。
