WidgetExternBase Class

Members


int getClassID ( ) #

Returns a unique class ID.

Return value

Unique class ID.

Ptr<Gui> getGui ( ) const#

Returns the Gui smart pointer.

Return value

Gui smart pointer.

int getKeyActivity ( unsigned int key ) #

Checks the keyboard key.

Arguments

  • unsigned int key - Key code.

Return value

Returns 1 if the key is used by widget.

Ptr<Widget> getWidget ( ) const#

Returns the Widget smart pointer.

Return value

Widget smart pointer.

Ptr<WidgetExtern> getWidgetExtern ( ) const#

Returns the WidgetExtern smart pointer.

Return value

WidgetExtern smart pointer.

void arrange ( ) #

Calculates the widget size.

void checkCallbacks ( int x, int y ) #

Checks widget callbacks.

Arguments

  • int x - Mouse X coordinate.
  • int y - Mouse Y coordinate.

void destroy ( ) #

Destroys the widget resources.

void expand ( int width, int height ) #

Expands the widget size.

Arguments

  • int width - Maximum available width.
  • int height - Maximum available height.

void keyPress ( unsigned int key ) #

Keyboard press event (scan code).

Arguments

  • unsigned int key - Key code.

void textPress ( unsigned int unicode ) #

Keyboard press event (virtual key).

Arguments

  • unsigned int unicode - Virtual key code.

void update ( float ifps ) #

Widget update function.

Arguments

  • float ifps - Inverse FPS value.

void preRender ( ) #

Widget pre-render function executed after the update() and before the render() function. This method is used to make necessary preparations for rendering (e.g. prepare a texture) after the update() and is called automatically for WidgetSpriteViewport and WidgetSpriteNode to ensure proper rendering of the widgets during render(). In case you implement a custom GUI or widgets using the WidgetExtern class you should put all such rendering preparations to this method and call Gui::preRender()preRender() manually after update().

void render ( ) #

Renders the widget.

void updatePositions ( ) #

Updates the widget's screen coordinates. This function is called after the arrange() and expand() functions.
