reset(): Not really useful anymore (legacy)

was_pressed() → bool: Checks if this button was pressed since the last time this method was called.

remove(): Remove the button from the gui.

Parameters:: point_positions (List[Vector3D]) – List of positions for the points in world.

remove(): Remove the debug points object from pybullet.

class pyrcf.utils.gui_utils.PybulletDebugFrameViz(cid: int, position: Vector3D = None, orientation: QuatType = np.array([0, 0, 0, 1]), line_length: float = 0.2, line_width: float = 2, duration: float = 0.0, draw_at_init: bool = True)

Draw a coordinate frame in pybullet as specified pose in the world.

_len = 0.2

_draw_lines(pos: Vector3D, ori: QuatType)

update_frame_pose(position: Vector3D, orientation: QuatType)

Update the pose of an existing frame viz in pybullet.

Parameters:

position (Vector3D) – Position of coordinate frame in world.
orientation (QuatType) – Orientation quaternion of the frame in the world.

remove(): Remove the frame viz from gui.

class pyrcf.utils.gui_utils.PybulletGUISlider(name: str, lower_lim: float, upper_lim: float, default_val: float, cid: int, mapping_function: Callable[[float], float] = lambda x: ...)

Create a slider gui in pybullet.

update_text(text: str)

Update the text string for this debug object.

Parameters:: text (str) – The new text to replace with.

remove(): Remove text from pybullet.

class pyrcf.utils.gui_utils.PybulletTextWithRateTrigger(text_position: Tuple[float, float, float], rate: float = 1, default_text: str = '', text_color: Tuple[float, float, float] = (0, 0, 0), text_size: float = 3.0, lifetime: float = 0.0, cid: int = 0)

Bases: PybulletText

Add text to pybullet sim world gui, that will only change at the specified rate (even if update_text is called at a higher frequency). This is useful if this method is called in a high frequency loop such as a control loop, and text has to be rendered only at a lower frequency.

_trigger

update_text(text: str)

Update the text string for this debug object. Will only be triggered if the specified rate is satisified (lower bound).

Parameters:: text (str) – The new text to replace with.

Handles a Tk window (called ‘master’).

master_widget

trigger

update(): The update method to be called in a loop to refresh all the widgets attached to this window. This will call the master update only if the rate specified during construction is met.
