# Deploying TQt Applications

This document lists the platform-specific files needed to distribute TQt applications. We do not include any compiler-specific files that may also be required. (See also, Window System-specific Notes.)

- Static TQt Applications
- Dynamic TQt Applications
  - Distributing Plugins
- Dynamic Dialogs

## Static TQt Applications

To distribute static TQt applications, you need the following file for all platforms:

- your application's executable

## Dynamic TQt Applications

To distribute dynamic TQt applications, you will need the following files for all platforms:

- application executable
- the TQt library

The TQt library must either be in the same directory as the application executable or in a directory which is included in the system library path.

The library is in provided by the following platform specific files:

Platform | File
--- | ---
Windows | `qt[version].dll`
Unix/Linux | `libqt[version].so`
Mac | `libqt[version].dylib`

version includes the three version numbers. For threaded builds the version is prefixed with -mt.

### Distributing Plugins

You must include any plugin files required by the application.

Plugins must be put into a subdirectory under a directory known to TQt as a plugin directory. The subdirectory must have the name of the plugin category (e.g. `styles`, `sqldrivers`, `designer`, etc.).

TQt searches in the following directories for plugin categories:

- Application specific plugin paths
- Build-directory of TQt
- The application directory

Application specific plugin paths can be added using TQApplication::addLibraryPath(). The build-directory of TQt is hardcoded in the TQt library and can be changed as a part of the installation process (see the distributor-example.html Distributor example).

## Dynamic Dialogs

For dynamic dialogs if you use TQWidgetFactory, you need the following files for all platforms:

- The same files as used for dynamic TQt applications
- The TQUI Library

The TQUI library is provided by the following platform specific files:

Platform | File
--- | ---
Windows | `tqui.lib`
Unix/Linux | `libtqui.so`
Mac | `libtqui.dylib`

The TQUI library must either be in the same directory as the application executable or in a directory which is included in the system library path.
