A Qt-Widget to get local file and folder-paths in an optimized and simple way.

The QPathEdit class was designed to provide a widget that allows the user to easily enter or select a local file or directory path. The widget comes with a plugin for QtCreator.

The QPathEdit class provides the following features:

• Appereance: The Edit is composed of a QLineEdit and QToolButton. It uses natives styles. It should look "normal" on any plattform. It provides 3 different styles to allows customisation of the way these components are displayed.
• Dialog: The user will be able to select his path using QFileDialog. The dialog can be customized to a limited amount.
• Validation: The edit automatically validates entered and selected paths and makes shure, that it always returns a valid path to your program.
• Editable: The edit can be editable or readonly. If editable, the validator will mark invalid paths and an auto completer will simplify path entering.
• Completer: The edit uses an auto completer, that uses the underlying file-system to provide paths as autocompletion to make entering paths even easiert. It can be turned on and off.
• QtCreator Plugin: The edit widget comes with an designer-plugin for Qt-Creator, to make it possible to user the pathEdit insider .ui files.

The package is providet as qpm package, de.skycoder42.qpathedit. To install:

1. Install qpm (See GitHub - Installing, for windows see below)
2. In your projects root directory, run qpm install de.skycoder42.qpathedit
3. Include qpm to your project by adding include(vendor/vendor.pri) to your .pro file

Check their GitHub - Usage for App Developers to learn more about qpm.

Important for Windows users: QPM Version 0.10.0 (the one you can download on the website) is currently broken on windows! It's already fixed in master, but not released yet. Until a newer versions gets released, you can download the latest dev build from here:

• https://storage.googleapis.com/www.qpm.io/download/latest/windows_amd64/qpm.exe
• https://storage.googleapis.com/www.qpm.io/download/latest/windows_386/qpm.exe

Since the QPathEdit is just a simple widget, you can use it like any other widget. The following example will create a simple window with the QPathEdit inside. If the user enters a path, the new path will be logged on the console:

#include <QApplication>
#include <QWidget>
#include <QVBoxLayout>
#include <QPathEdit>

int main(int argc, char *argv[])
{
   QApplication a(argc, argv);
   
   QWidget window;
   QVBoxLayout *layout = new QVBoxLayout(&window);
   QPathEdit *edit = new QPathEdit(&window);
   layout->addWidget(edit);
   window.setLayout(layout);
   
   QObject::connect(edit, &QPathEdit::pathChanged, [](QString path){
       qDebug() << path;
   });
   
   window.show();
   return a.exec();
}

To install the plugin, you need to copy the right file from the designerplugins.zip zip-package to the QtCreators designer plugin path. There are a number of subfolders for operating systems I've created the plugin for. If yours is not present, you need to compile the plugin yourself. Copy file (for example qpatheditplugin.dll) into QtCreators path. The default path would be:

• Windows: <path_to_qt>/Tools/QtCreator/bin/plugins/designer
• OsX: <qt_creator_bundle>/Contents/PlugIns/designer
• Linux: <path_to_qt>/Tools/QtCreator/lib/Qt/plugins/designer

After restarting the creator, navigate to the designer and to "Tools > Form Editor > About Qt Designer Plugins". The plugin should appear there. In the editor itself, you can find it inside the "Input Widgets" Section.

The documentation is available within the releases and on github pages.

The documentation was created using doxygen. It includes an HTML-documentation and Qt-Help files that can be included into QtCreator (QtAssistant) to show F1-Help (See Adding External Documentation for more details).

The edit uses a default icon for joined dialog buttons. The icon was downloaded from http://www.fatcow.com/free-icons.
