GtkFileChooserButton in Folder Select mode can return the folder URI. Use urlparse module to convert URI to path. This works even with bookmarks. Hope this solves your issue. import urlparse folder_uri = filechooserbutton_meas.get_uri() folder = urlparse.urlparse(folder_uri).path

Is this still a problem for you? Perhaps exposing the system level functionality through your app's UI might be the best way to go. I suspect locking at the app level would be considered a bug by the system developers so it's not offered.

You just need to learn the CMake language. It is the language of the CMakeListes.txt files that are all over the project. This language specifies how to build the project. And this language is independent from the QtCreator IDE that we are using. So, you can do builds without QtCreator and create CMakeListes.txt manually where you wish. Back to the ...

Aptik is really good. By using it and Deja-Dup I have just blown away a system (on purpose) and recreated it in only a hour or so. Here's a picture of the Aptik screen. I've used the first 3 buttons to save my configuration and reload it onto the new system. The 4th button seems to largely duplicate Deja-Dup's functionality, so I didn't use it. The ...

Create another project with New Project > Ubuntu > QML App with Simple UI (qmlproject), Framework ubuntu-sdk-14.10-qml. Copy 'content', 'doc' and 'clocks.qml' from the "clocks" example to this new project. Rename clocks.qml to Clocks.qml. Add ...

I've just verified and seems QCameraInfo::availableCameras() always returns an empty list indeed. This seems like a bug. I've reported it here: https://bugs.launchpad.net/ubuntu/+source/qtmultimedia-opensource-src/+bug/1438072 Please confirm and add any other findings you might have related to QCamera and C++.

If your application is designed to run under application confinement (usually required if you plan to ship through the click store), it will be restricted to access files only within its own silo.

You really should ask only one question per question but: 1) Python is a really good choice for building GUI apps 2) You use some kind of toolkit to build GUI applications, if you want to develop apps that work in both Windows and Linux, QT is the best option to me. To use python and qt you can use pyqt. You will find some tutorials in the pyqt page 3) ...
