+@brief Dialog - Animations control, loading animation, weight for skeleton and playlist composition.
+@details Dialog loads animations files and weight for skeleton animation. Files can also be unloaded.
+For loading / unloading and animation control dialog uses the functionality of CEntity class.
+But the main opportunity for dialogue is to generating animations playlists.
+Also, the dialogue has a control element to select the current shape (emit a signal changeCurrentShape()) 
+and switch of playlist/mixer (this functionality will soon be transferred to another specialized dialogue).
+As each shape has its own list of loaded animations and playlist,when you switch your current shape,
+the dialogue should be notified through the slot setCurrentShape ().

+
+1. Using the Qt Q_SIGNALS/SLOT can be set current color by class methods setColor() and 
+changes in current color(QSliders or QColorDialog) emits the signal colorChanged().
+
+2. Using wrapper, create wpapper struct, example:
+@code
+struct CAmbientColorWrapper : public IPSWrapperRGBA
+{

+	void set(const NLMISC::CRGBA &col) { S->setSunAmbient(col); }

+@mainpage Object Viewer Qt
+@author Dzmitry Kamiahin <dnk-88@tut.by>, (C) 2010
+
+@section introduce Introduce
+@details
+The Object Viewer Qt (ovqt) is a tool for working with graphics technology NeL data, 
+which can be useful durung the development and preparation of the game content. 
+The tool can be used in different tasks:
+- Loading and viewing NeL data (.shape, .ps) files with the ability to set wind power, color light.
+- Viewing animation shape (loading .anim, .skel, .swt files) using playlist or slot manager(mixing animation).
+- Create and modify NeL particle system. 
+- Viewing water shape with the ability to set day/night.
+- Modify skeleton (.skel files, .scale file).
+- Create and modify micro-vegetation material (.vegetset files)
+- Viewing landscape (.zonel files)
+- Dialog allows to specify graphical, sound, search path and landscape settings.
+
+@section project_structure Overview of the Object Viewer Qt Project Structure
+@details
+OVQT - consists of several major subsystems. Each subsystem performs its defined part of the task. 
+Through Modules:: provides access to all other program subsystems. 
+
+Program has the following subsystems:
+- @ref Modules - Main modules aggregated all parts of the program.
+- @ref NLQT::CConfiguration - is responsible for loading and saving settings from the configuration file. As well as search path of data.
+- @ref NLQT::CObjectViewer - main subsystem of the program, which initializes the driver, creates a scene and other supporting elements. 
+It is a container for loaded models, which can further be viewed and animated.
+- @ref NLQT::CMainWindow - is responsible for the GUI.
+- @ref NLQT::CParticleEditor - is responsible for the particle systems and provides access to a container that keeps all the loaded particle systems. 
+And also allows you to view an animation of particle systems, with the ability to control its parameters.
+- @ref NLQT::CVegetableEditor - is responsible for the landscape zones and the editor of vegetation. 
+Allows you to load and view the landscape. Also has the ability to create and edit the parameters of the micro-vegetation.
+- @ref NLQT::CSoundSystem -  is responsible for the sound in the program.
+
+<b>
+The structure of the GUI in the editor of the particles. 
+</b><br>
+This can be useful for new developers who want to add more new dialogs or to improve the functionality of existing dialogues.
+<img src="gui_struct.png" alt="Particle Workspace">
+ParticleWorkspace dialogue uses the technique of model-view. 
+Using the signal/slot link QTreeView with QStackWidget, Editor properties dialog. 
+When you select an item in QTreeView, QStackWidget displays the necessary page(PageWidget) where you can edit the element of the particles system. 
+Each page is made in the designer and has a separate forms(.ui). 
+In accordance with the recommendations of dialogues design, with a large number of items,every page uses QTabWidget. 
+In case when there is a great number of controls, and not everything you want to display, 
+it's used the dynamic creation of tabs. Moreover, each tab uses a separate forms(.ui).
+
+@section for_new_developer Guide for new developers of the Object Viewer Qt.
+@details
+ First of all, to begin developing dialogues that add new features ovqt,
+it is needed to read the documentation Qt libs (http://doc.qt.nokia.com/) and NeL documentation.
+ 
+ In order to have convenient using of the tool and its further development, 
+it is expected to make a unified interface that is why all dialogs should adhere to a standard design, 
+which will be written further. For this goals program provides some additional widgets, 
+which are recommended to use. As in the development Qt Designer is actively used. 
+To get access to founded here widgets from the designer,the technique promotion is used, 
+which can be found <a href="http://doc.qt.nokia.com/4.5/designer-using-custom-widgets.html"> here </a>.
+<ol>
+<li><b>
+CEditRangeUIntWidget / CEditRangeIntWidget / CEditRangeFloatWidget
+</b><br>
+Widgets provides a slider that allows you to specify an integer (or float, depending on which widget used) number within a set range. 
+The range is also can be set by the user, or for a more accurate selection of numbers, either for receiving large values. 
+As there may be situations when the range that a user requests,has to be restricted, and widget provides methods that allow you to do so.
+<br><br>
+<img src="cedit_range_int_widget.png" alt="CEditRangeIntWidget">
+<br>
+<img src="cedit_range_float_widget.png" alt="CEditRangeFloatWidget">
+@see
+@ref NLQT::CEditRangeUIntWidget, @ref NLQT::CEditRangeIntWidget, @ref NLQT::CEditRangeFloatWidget 
+
+<li><b>
+CColorEditWidget
+</b><br>
+Using this widget you can set the color(RGBA) using the four sliders or through the color selection dialog.
+<br><br>
+<img src="cedit_color_widget.png" alt="CColorEditWidget">
+@see
+@ref NLQT::CColorEditWidget
+
+<li><b>
+CDirectionWidget 
+</b><br>
+This widget helps to choose from several preset directions, or to choose a custom one. 
+To use it you have to create a wrapper.
+<br><br>
+<img src="cdirection_widget.png" alt="CDirectionWidget">
+@see
+@ref NLQT::CDirectionWidget
+</ol><br><br>
+
+To further convinience of instrument using dialogues interface is recommended to make as follows. 
+The most sophisticated tools of the program, should take the form of three dock windows (example shown in the screenshot).
+<img src="object_viewer_qt_window.png" alt="Object Viewer Qt">
+<ol>
+<li>
+The first dock window - is a control dock window, it should focus all of the control functions of general purpose 
+(for example: start/stop/pause animations or particles system). 
+It is recommended to perform of the horizontal type window and placed in the bottom of the main window.
+<li>
+The second dock window - is a list or a tree of items. In which selecting of the current element, 
+which assumes to modify or viewis possible.Operations "add/remove/insert or other" items are recommended to make as a popur menu. 
+It is recommended to perform of the vertical type window and placed in the left of the main window.
+<li>
+The third dock - is an editor for properties of the element that was selected in the list or in the tree of elements. 
+As all the controls occupy much space or do not fit at all, you have to use tabs QTabWidget, 
+which in total can contains quite a lot of elements. 
+For a small number of tabs it is allowed to use both horizontal and vertical location. 
+But with a large number of tabs, it is necessary to apply the vertical arrangement. 
+It is recommended to perform of the vertical type of window and placed in the right of the main window.
+</ol>
+In the simple dialogues do not necessary to use all three windows, but user has to adhere to the recommendations given above as well.
+Also, <b>all dialogs must use the qt layout manager</b>. And if you do not use the designer, 
+make sure you use the qt tools internationalization applications.
+<br><br>
+In ovqt for most dialogs their owner is NLQT::CMainWindow and in its methods creating and initializing all dependent dialogs occur. 
+For the convenience of the program using, most dialogues are created in the form of docking windows. 
+Creating all the dialogues are carried out in a private method NLQT::CMainWindow::createDialogs(). 
+Hence, it is necessary to add operations in this method to create new dialogues. 
+But we must take into account that at this moment is fully available only one component of the program CConfiguration, 
+to read the settings from the configuration file. The remaining components of the program are available only after the main window stays visible. 
+Calling the dialogues going through the menu or the toolbar, usually it is a checkable item. 
+Adding of the new menu items or items toolbars is need in methods NLQT::CMainWindow::createMenus(), NLQT::CMainWindow::createToolBars().
