class mrpt::gui::CDisplayWindowGUI

A window with powerful GUI capabilities, via the nanogui library.

You can add a background mrpt::opengl::COpenGLScene object rendered on the background of the entire window by setting an object in field background_scene, locking its mutex background_scene_mtx.

Refer to nanogui API docs or MRPT examples for further usage examples. A typical lifecycle of a GUI app with this class might look like:

nanogui::init(); {mrpt::gui::CDisplayWindowGUI win; win.drawAll(); win.setVisible(true); nanogui::mainloop(); } nanogui::shutdown();

Methods

void resize(unsigned int width, unsigned int height)

Resizes the window.

void setPos(int x, int y)

Changes the position of the window on the screen.

void setWindowTitle(const std::string& str)

Changes the window title.

void setLoopCallback(const std::function<void(void)>& callback)

Every time the window is about to be repainted, an optional callback can be called, if provided via this method.

void setDropFilesCallback(const std::function<bool(const std::vector<std::string>&)>& callback)

Sets a handle for file drop events.

template <typename... Args>
static Ptr Create(Args&&... args)

Class factory returning a smart pointer.
