klampt.vis.glinterface module

Defines the GLPluginInterface class, which is a unified base class for plugins to the klampt.vis module.

class klampt.vis.glinterface.GLPluginInterface[source]

Bases: object

Users can add their own hooks into the visualizer by overloading this class’s methods. Each method should return True if the user event was processed. A return value of True stops cascading events to a parent interface.

window

the window to which this plugin is attached. May be None if not attached to an OpenGL window.

Type:: QtGLWindow or GLUTWindow

view

the viewport that is currently being used for this plugin.

Type:: GLViewport

actions

internally used.

Type:: list

initialize()[source]

Called by backend after the GL context is created but before the event loop starts.

Return type:: bool

displayfunc()[source]

Return type:: bool

display()[source]

Return type:: bool

display_screen()[source]

Return type:: bool

reshapefunc(w, h)[source]

Return type:: bool

keyboardfunc(c, x, y)[source]

Return type:: bool

keyboardupfunc(c, x, y)[source]

Return type:: bool

mousefunc(button, state, x, y)[source]

Return type:: bool

motionfunc(x, y, dx, dy)[source]

Return type:: bool

mousewheelfunc(dhorizontal, dvertical, x, y)[source]

Return type:: bool

idle()[source]

Return type:: bool

eventfunc(type, args='')[source]

Generic hook for other events, e.g., button presses, from the GUI

Return type:: bool

closefunc()[source]

Return type:: bool

add_action(callback, short_name, key, description=None)[source]

Defines a new generic GUI action. The action will be available in a menu in Qt or as keyboard commands in GLUT.

Return type:: None

reshape(w, h)[source]

Asks to resize the GL window

Return type:: None

idlesleep(seconds)[source]

Asks to sleep the idle function for seconds seconds.

Return type:: None

modifiers()[source]

Retrieves a list of currently pressed keyboard modifiers. Values can be any combination of ‘ctrl’, ‘shift’, ‘alt’.

Return type:: List[str]

refresh()[source]

Asks for a redraw

Return type:: None

draw_text(point, text, size=12, color=None)[source]

Draws text of the given size and color at the point (x,y) or (x,y,z). The former method is usually called during display_screen.

Return type:: None

click_ray(x, y)[source]

Returns the world-space ray associated with the camera click at pixel coordinates x,y.

Return type:: Tuple[Sequence[float], Sequence[float]]

viewport()[source]

Returns the Viewport instance associated with the current GL view. Used for interfacing with C++ widgets.

Return type:: Viewport
