I have a gpx file. I need a open source library that i can give it the gpx file and that it will present the route on a map. Does anyone know such a thing?
I'm writing in c++ on windows xp.
thanks in advance!!
There exists a bunch of Frameworks to map the OSM APIs to different languages.
Please check out this wiki-page from OSM: http://wiki.openstreetmap.org/wiki/Develop/Frameworks
I think what you search for can be found under Widgets like for example "COSMCtrl 1.1.3"

At the moment I am creating an Editor for Textures and I want to choose the textures during runtime. Later I would like to choose the save directory for new textures.
I found the
How to: Open Files Using the OpenFileDialog Component. But I think this is not the solution.
(assuming you are on Windows, pas per screenshot)
If you simply want to select a folder, you can use SHBrowseForFolder.

You need to look at the Common Dialog Library.

Or, if you are only interested in Vista/Windows 7 support, you could consider the Common Item Dialogs instead.

For 'native' C++ you wouldn't be able to easily use the .NET components that your link refers to.
I have solved my problem with using the dirent.h file. I have acknowledge of this file by founding this post How can I get the list of files in a directory using C or C++?
I have write my own fileexplorer by using dirent.h and SFML.
Sorry if i can't illustrate my problem.
but thanks for the replies (:
We want to move to Qt for our widget library. Currently we're using WX and it's compatible with chm. I can't find anything to suggest that Qt is the same. We've invested a bunch in CHM tools for the non-technical people to write help files.
Is there a way to view chm with Qt?
If not, is there a reasonably easy path from chm to whatever IS viewable from Qt?
Plain HTML definitely is. Qt contains a full HTML rendering core (WebKit).
Plus Qt has some internal format (packed HTML, similar to chm) https://doc.qt.io/archives/qq/qq28-qthelp.html
Oh and: http://web.archive.org/web/20120712115053/http://lists.trolltech.com/qt-interest/2005-03/thread00621-0.html explains how to open chm
Since you're using CHM you're probably not writing cross platform code. Just call ShellExecute passing the chm file full path name as parameter and Windows will open it for you.
We want to persist some user settings int he GUI part of our code. I used to do Win32 programming exclusively and the typical way this was done was with registry settings.
I assume that this should be done with configuration files, but was wondering if there was a library or cross platform wrapper that made key/value pair persistence very easy.
Qt's QSettings class handles this:
http://doc.qt.nokia.com/4.6/qsettings.html
Boost.PropertyTree supports XML, JSON, INI config files.
There is also JSON for a lighter alternative of XML. Lots of implementations on that page too.
Qt 4 has a class for it, named QSettings. Looks exactly like what you need.
Why not use an XML as the configuration file. Then you only have to find a cross platform XML library which is easier IMO.
Here is a list of nice XML parsing solutions for C++.
Old school Berkley DB comes to mind.
Have a look at Tokyo Cabinet or at Embedded InnoDB.
In the old days we used .ini files in windows. Here is a portable version of an ini file read/write library
It will work on Windows as well as Linux.
I'm using wxWidgets to write cross-plafrom applications. In one of applications I need to be able to load data from Microsoft Excel (.xls) files, but I need this to work on Linux as well, so I assume I cannot use OLE or whatever technology is available on Windows.
I see that there are many open source programs that can read excel files (OpenOffice, KOffice, etc.), so I wonder if there is some library that I could use?
Excel files it needs to support are very simple, straight tabular data. I don't need to extract any formatting except column/row position and the data itself.
Suggestedd reference: What is a simple and reliable C library for working with Excel files?
I came across other libraries (chicago on sf.net, xlsLib) but they seem to be outdated.

I can say that I know of a wxWidgets application that reads Excel .xls and .xlsx files on any platform. For the .xlsx files we used an XML parser and zip stream reader and grab the data we need, pretty easy to get going. For the .xls files we used: ExcelFormat, which works well and we found the author to be very generous with his support.
Maybe just some encouragement to give it a go? It was a couple of days work to get working.
Maybe http://www.libxl.com/ can help ?
I think that it is not something easy to do. xls files are quite complex and it is a proprietary format.
Maybe this is a stupid idea but why don't you upload and access your doc with Google docs. There are some apis to access your doc.
2 potential problems:
- Your app needs internet access
- Currently there is no C++ api.
But there are api for several languages including python see http://code.google.com/intl/fr/apis/gdata/articles/python_client_lib.html
I am unable to find any open source libraries to render ODF documents using C++. I found ODKit suporting Java and AODL for .NET C#.
Does any one have any idea or provide me any pointers.
I found a Qt source to parse ODF. Qt already has built in ODF writer.
KOffice supports ODF and is written in C++. I suspect they may have solved whatever it is you are trying to solve. http://www.koffice.org
It may not be the most elegant solution but OpenOffice itself is capable of rendering and the OOoSDK can be used from C++ as seen here for writer and here for spreadsheet.
There is none. You're better AODL or any of the other libs available (python, perl, java, etc) and doing a binding to it
KOffice can be an idea, but if I just want to display an odt file in a nice Qt QWidget, but I don't want to depends on DBus and a lots of Kde feature.
The Idea is to take a look a Flake and KoText libs as Thomas Zanders says on this Forum.
