Qt: OCCT Overview (C++|Qt Widgets) {#samples_qt_overview}
==========
The Overview Qt application provides code snippets for basic usage of C++ API of various OCCT functionality.
The samples are organized in several categories according to relevant module of OCCT:
* Geometry
* Topology
* Triangulation
* DataExchange
* OCAF
* Viewer 2d
* Viewer 3d
Each sample presents geometry view, C++ code fragment and sample output window.
This sample is described in the @ref samples__novice_guide "Novice guide" for new users.

1. Contents
-----------------------
The directory <i> samples/qt/OCCTOverview </i> contains the folders and files of the Qt OCCT Overview application:
* Files **OCCTOverview.pro** and **OCCTOverview0.pro** are Qt project files.
* File **genproj.bat** to denerate MS Visual Studio project.
* File **msvc.bat** to run MS Visual Studio project.
* File **make.sh** to build of the application on Linux.
* Files **run.bat** and **run.sh** to run the application.
* Files **env.bat** and **custom.bat** are called from *genproj.bat*, *msvc.bat*, *run.bat*.
File *custom.bat* should be defined by user to provide paths to QT directory and OCCT installation directory (see *custom.bat.template*).
* **src** and **res** directories provide source and resources files.
The directory <i> samples/OCCTOverview/code </i> contains the source code of samples.
2. How to build Qt OCCT Overview application
---------------------------------
* Edit custom.bat file. It is necessary to define following variables:
* **QTDIR** path to where Qt is installed
* **CASROOT** path to where Open CASCADE binaries are installed.
* Build the application:
* On Windows:
* Generate project files: `> genproj.bat vc141 win64 Debug`
* Launch MS Visual Studio: `> msvc.bat vc141 win64 Debug`
* Build the application using MS Visual Studio.
* On Linux: Launch building of the application by make.sh script
3. Running the application
--------------------------
* On Windows:
~~~~
> run.bat vc141 win64 Debug
~~~~
* On Linux:
~~~~
> run.sh
~~~~
4. How to use the OCCT Overview application:
---------------------------------
* To select a samples category use the *Category* menu.
* To run concrete sample using the menu to the right of the category menu.
* See the source code in the *Sample code* window. Сopy the code if needed.
* See the sample output in the *Output* window if it exist.
* Zoom, pan and rotate a geometry in the mail window using the mouse.
See hints how to use the mouse in down hints panel.
