Unigine::Gui Class
| Header: | #include <UnigineGui.h> |
Creates a GUI. Different types of GUI widgets can be either added to one of the following:
- To the system GUI (Unigine user interface) that is rendered on top of application window.
- To the GUI object positioned in the world. In this case, any postprocessing filter can be applied.

CALLBACK_INDEX#
| Name | Description |
|---|---|
| SHOW = 0 | Callback is used when a widget is shown. Supported by all widgets. |
| HIDE = 1 | Callback is used when a widget is removed via Gui::removeChild(). Supported by all widgets. |
| FOCUS_IN = 2 | Callback is used when a widget is focused. Supported by all widgets. |
| FOCUS_OUT = 3 | Callback is used when a widget loses focus. Supported by all widgets. |
| CHANGED = 4 | Callback is used when a widget has changed its state. Supported by the following widgets:
|
| CLICKED = 5 | Callback is used when the mouse is clicked somewhere on a widget. Supported by the following widgets:
|
| DOUBLE_CLICKED = 6 | Callback is used when the mouse is double-clicked somewhere on a widget. Supported by the following widgets: |
| PRESSED = 7 | Callback is used when a mouse button or ENTER (RETURN) is pressed, while the mouse pointer is somewhere on a widget. Supported by the following widgets: |
| RELEASED = 8 | Callback is used when the mouse was released after clicking somewhere on a widget. Supported by the following widgets: |
| KEY_PRESSED = 9 | Callback us used when a key (by scan code) is pressed while a widget is in focus. Supported by the following widgets:
Scan code - is a code assigned to avery key on the keyboard. Keyboard drivers use scan codes to detect which key is pressed. Scan codes are assigned to leys on the hardware level and are not affected by the states of modifiers like Caps Lock, Num Lock, Scroll Lock, Shift, Alt, and Ctrl making it possible to implement identical control on different types of keyboards (QWERTY, AZERTY, QWERTC, etc.). Scan codes are used when only a physical position of a key (a button) is important (e.g. in the ControlsApp class or Console key. |
| TEXT_PRESSED = 10 | Callback us used when a virtual key is pressed while a widget is in focus. Supported by the following widgets:
Virtual key - is a value to which a scan code was converted by an Operating System (e.g., the Q scan code will have the Q virtual key on a QWERTY-keyboard, while on an AZERTY-keyboard it will have the A virtual key; or NUMPAD_DIGIT_7 scan code can be translated into virtual NUMPAD_HOME or NUMPAD_DIGIT_7 depending on the current Num Lock state. Virtual keys are used, when it is important to know what exactly did user type (not just the physical button, but rather a letter). |
| ENTER = 11 | Callback is used when the mouse pointer enters a widget. Supported by all widgets. |
| LEAVE = 12 | Callback is used when the mouse pointer leaves a widget. Supported by all widgets. |
| DRAG_MOVE = 13 | Callback is used when a focused widget is moved. |
| DRAG_DROP = 14 | Callback is used when a drag-and-drop operation is performed with a widget. Supported by all widgets. A callback can receive dragged widgets inside additional arguments. Clicked or pressed callbacks receive a mouse button or a key inside an additional callback argument. |
| REMOVE = 15 | Callback is used when a widget is removed. |
| NUM_CALLBACKS = 16 | Number of GUI callbacks. |
