Unigine::Widgets

Unigine::Widgets are user classes that allow to code user interface only once and use them for both internal GUI (in-app) and external one (rendered in separate windows):

• If the Unigine-based application is run without the Interface plugin, widgets will be created inside the window, in the same way as default GUI is usually rendered.
• If the Interface plugin is loaded on the application start-up (via extern_plugin console command), widgets will be automatically created in separate windows in addition to the main application window.

Unigine::Widgets act identical to UnigineScript widgets and support completely the same interface:

• Unigine::Widgets::Button — the same as WidgetButton
• Unigine::Widgets::Canvas — the same as WidgetCanvas
• Unigine::Widgets::CheckBox — the same as WidgetCheckBox
• Unigine::Widgets::ComboBox — the same as WidgetComboBox
• Unigine::Widgets::Dialog — the same as WidgetDialog
• Unigine::Widgets::DialogColor — the same as WidgetDialogColor
• Unigine::Widgets::DialogFile — the same as WidgetDialogFile
• Unigine::Widgets::DialogImage — the same as WidgetDialogImage
• Unigine::Widgets::DialogMessage — the same as WidgetDialogMessage
• Unigine::Widgets::EditLine — the same as WidgetEditLine
• Unigine::Widgets::EditText — the same as WidgetEditText
• Unigine::Widgets::GridBox — the same as WidgetGridBox
• Unigine::Widgets::GroupBox — the same as WidgetGroupBox
• Unigine::Widgets::HBox — the same as WidgetHBox
• Unigine::Widgets::HPaned — the same as WidgetHPaned
• Unigine::Widgets::Icon — the same as WidgetIcon
• Unigine::Widgets::Label — the same as WidgetLabel
• Unigine::Widgets::ListBox — the same as WidgetListBox
• Unigine::Widgets::ScrollBox — the same as WidgetScrollBox
• Unigine::Widgets::Slider — the same as WidgetSlider
• Unigine::Widgets::Spacer — the same as WidgetSpacer
• Unigine::Widgets::Sprite — the same as WidgetSprite
• Unigine::Widgets::TabBox — the same as WidgetTabBox
• Unigine::Widgets::TreeBox — the same as WidgetTreeBox
• Unigine::Widgets::VBox — the same as WidgetVBox
• Unigine::Widgets::VPaned — the same as WidgetVPaned
• Unigine::Widgets::Window — the same as WidgetWindow

Also, there are three additional widgets available:

• Unigine::Widgets::DockBox — a widget that can be dragged and docked inside a window.
• Unigine::Widgets::Graph — a widget to create flow graphs. Unigine::Schemer editor is implemented based on this class.
• Unigine::Widgets::MdiBox — a widget to create multiple windows inside other windows

1. Include the necessary headers for widgets you are going to create in your script:
   Source code (UnigineScript)

   #include <core/systems/widgets/widget.h>
   #include <core/systems/widgets/widget_window.h>

2. Create a widget:
   Source code (UnigineScript)

   int init() {
   	
   	// You can declare the namespace for convenience
   	using Unigine::Widgets;
   	
   	// Create Unigine::Widgets::Window
   	Window window = new Window("Unigine::Widgets::Window");
   	
   	// Add the widget to the rendered GUI
   	addChild(window,ALIGN_OVERLAP | ALIGN_CENTER);
   	
   	return 1;
   }

   When the application is run, either internal WidgetWindow or external InterfaceWidgetWindow will be automatically created depending on whether the Interface plugin is used or not.
