I want to know how to access the paths of files in the qrc file in order to use them as strings in an array.
An example of qrc file is:
<!DOCTYPE RCC><RCC version="1.0">
<qresource prefix="">
<file>images/1.jpg</file>
<file>images/2.jpg</file>
<file>images/3.jpg</file>
<file>images/4.jpg</file>
</qresource>
</RCC>
I want to use it in the following manner:
for(int i=0;i<4;i++)
{
path=image_path[i];
}
where path is an qlist that can be later used for accessing the respective images.
There seems to be a simple way of doing it using QDirIterator.
It might break if you have a directory called ":" in the current working directory and you expect that to be parsed instead in the future. Anyhow, that should not be a concern for now.
QStringList imageFileList;
QDirIterator dirIterator(":", QDirIterator::Subdirectories);
while (dirIterator.hasNext()) {
QFileInfo fileInfo = it.fileInfo();
if (fileInfo.isFile()) // Do not add directories to the list
imageFileList.append(it.next());
}
Alternatively, this requires quite a bit of involvement, but I think it works. I am afraid there is no more convenient way as of writing this.
main.qrc
<!DOCTYPE RCC><RCC version="1.0">
<qresource prefix="">
<file>images/1.jpg</file>
<file>images/2.jpg</file>
<file>images/3.jpg</file>
<file>images/4.jpg</file>
</qresource>
</RCC>
main.cpp
#include <QXmlStreamReader>
#include <QString>
#include <QFile>
#include <QTextStream>
int main()
{
QTextStream standardOutput(stdout);
QFile file("main.qrc");
if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) {
standardOutput << "File open error:" << file.errorString() << "\n";
return 1;
}
QXmlStreamReader inputStream(&file);
while (!inputStream.atEnd() && !inputStream.hasError()) {
inputStream.readNext();
if (inputStream.isStartElement()) {
QString name = inputStream.name().toString();
if (name == "file")
standardOutput << "file: :/" << inputStream.readElementText() << "\n";
}
}
return 0;
}
main.pro
TEMPLATE = app
TARGET = main
QT = core
SOURCES += main.cpp
Build and Run
qmake && make && ./main
Output
file: :/images/1.jpg
file: :/images/2.jpg
file: :/images/3.jpg
file: :/images/4.jpg
