UserInterface Class

Members


static UserInterfacePtr create ( const Ptr<Gui> & gui, const char * name, const char * prefix = 0 ) #

UserInterface constructor.

Arguments

  • const Ptr<Gui> & gui - GUI smart pointer.
  • const char * name - User interface name.
  • const char * prefix - Names prefix.

int getCallback ( int num, int callback ) const#

Returns the number of a given callback function.

Arguments

  • int num - Widget number.
  • int callback - Callback type number. One of the callbacks defined in the Gui class (for example, CLICK, SHOW, HIDE, etc).

Return value

Callback number.

void * addCallback ( const char * name, Gui::CALLBACK_INDEX callback, Unigine::CallbackBase * func ) #

Adds a callback function of the specified type for the widget with the specified name.The signature of the callback function must be as follows:
Source code (C++)
void callback_function_name();

Arguments

  • const char * name - Widget name.
  • Gui::CALLBACK_INDEX callback - Callback type number. One of the callbacks defined in the Gui class (for example, CLICK, SHOW, HIDE, etc).
  • Unigine::CallbackBase * func - Callback pointer.

Return value

ID of the last added callback, if the callback was added successfully; otherwise, nullptr. This ID can be used to remove this callback when necessary.

void * addCallback ( const char * name, Gui::CALLBACK_INDEX callback, Unigine::CallbackBase1< Ptr<Widget> > * func ) #

Adds a callback function of the specified type for the widget with the specified name.The signature of the callback function must be as follows:
Source code (C++)
void callback_function_name(WidgetPtr widget);

Arguments

Return value

ID of the last added callback, if the callback was added successfully; otherwise, nullptr. This ID can be used to remove this callback when necessary.

void * addCallback ( const char * name, Gui::CALLBACK_INDEX callback, Unigine::CallbackBase2< Ptr<Widget>, Ptr<Widget> > * func ) #

Adds a callback function of the specified type for the widget with the specified name.The signature of the callback function must be as follows:
Source code (C++)
void callback_function_name(WidgetPtr widget1, WidgetPtr widget2);

Arguments

Return value

ID of the last added callback, if the callback was added successfully; otherwise, nullptr. This ID can be used to remove this callback when necessary.

void * addCallback ( const char * name, Gui::CALLBACK_INDEX callback, Unigine::CallbackBase3< Ptr<Widget>, Ptr<Widget>, int > * func ) #

Adds a callback function of the specified type for the widget with the specified name.The signature of the callback function must be as follows:
Source code (C++)
void callback_function_name(WidgetPtr widget1, WidgetPtr widget2, int arg3);

Arguments

Return value

ID of the last added callback, if the callback was added successfully; otherwise, nullptr. This ID can be used to remove this callback when necessary.

bool removeCallback ( const char * name, Gui::CALLBACK_INDEX callback, void * id ) #

Removes the specified callback from the list of callbacks of the specified type added for the widget with the given name.

Arguments

  • const char * name - Widget name.
  • Gui::CALLBACK_INDEX callback - Callback type number. One of the callbacks defined in the Gui class (for example, CLICK, SHOW, HIDE, etc).
  • void * id - Callback ID obtained when adding it.

Return value

True if the callback with the given ID was removed successfully; otherwise false.

void clearCallbacks ( const char * name, Gui::CALLBACK_INDEX callback ) #

Clears all callbacks of the specified type added for the widget with the given name.

Arguments

  • const char * name - Widget name.
  • Gui::CALLBACK_INDEX callback - Callback type number. One of the callbacks defined in the Gui class (for example, CLICK, SHOW, HIDE, etc).
