FWindowGLFW

namespace marengine
class FWindowGLFW : public FWindow
#include “Window/GLFW/WindowGLFW.h”

FWindowGLFW class is second implementation of IWindow. It is basic implementation of GLFW library and gives basic functions.

Subclassed by FWindowGLFWImGui

Public Functions

bool open(uint32_t width, uint32_t height, const char *name) final

Method is responsible for opening window with given width, height and its name.

Return

True if window opened correctly, false otherwise

Parameters

  • width: width of window

  • height: height of window

  • name: name of window, that shall be displayed

void close() final

Closes current window instance. Remember, it does not terminate library, closes window!

bool initializeLibrary() final

Initializes implementation library of window instance. It is called during MAREngine’s startup.

Return

True if window’s library initialized correctly, false otherwise

void terminateLibrary() final

Terminates window’s library. Called during MAREngine’s termination.

bool isGoingToClose() final

Checks if window is going to close after that frame and returns the result.

Return

True, if window is going to close, false otherwise

void setVerticalSync(int32_t vsSetValue) final

Sets vertical synchronization (decreases FPS if set on!).

Parameters

  • vsSetValue: vsSetValue equal to 1 sets VS. 0 disables it.

void clear() const final

Clears screen.

void swapBuffers() final

Swaps buffers and polls event.

bool isKeyPressed(int32_t key) const final

Checks, if given key at keyboard was pressed and returns result. For correct key value check Window/buttons_def.h file.

Return

True, if keyboard key was pressed, false otherwise.

Parameters

  • key: Keyboard value, to be checked if it was pressed.

bool isMousePressed(int32_t key) const final

Checks, if given key at mouse was pressed and returns result. For correct key value check Window/buttons_def.h file.

Return

True, if mouse key was pressed, false otherwise.

Parameters

  • key: Mouse value, to be checked if it was pressed.

Protected Attributes

class FWindowGLFWImGui : public FWindowGLFW
#include “Window/GLFW/WindowGLFW.h”

FWindowGLFWImGui class is third implementation of IWindow. It derives from FWindowGLFW implementation and updates mandatory methods for editor.

Public Functions

void initEditorGuiLibrary() final

Initializes GUI Editor Library with window instance, so that it can be used correctly. It is called during editor gui initialization.

void beginNewFrameEditorGuiLibrary() final

Begins new frame at editor GUI library. Called during every new frame.

void terminateEditorGuiLibrary() final

Terminates EditorGUI library, so that window afterwards can be closed correctly.
