event(self, QEvent) → bool
eventFilter(obj, event)

The canvas needs to grab keyboard input in order to reliably tell when a modifier key (shift or control) is down when a mouse button is pressed/released.

Some environments have trouble with passing the control key in events - a control-left-click is often mapped to a right-click. Therefore we do our best to capture on our own when the control key is down. Note that even this breaks for multiple control-clicks on Linux running under VMWare Fusion on Macs, because VMWare by default “lifts” the control key after the first click.

Parameters:
  • obj (not used) – not used
  • event (QEvent) – the event object

Add in the control modifier key to the button_release_event

Parameters:event (QMouseEvent) – the QMouseEvent that triggered this handler

self._key is matplotlib’s way of storing the modifier keys

mpl_connect(s, func)

Connect event with string s to func. The signature of func is:

def func(event)

where event is a matplotlib.backend_bases.Event. The following events are recognized

  • ‘button_press_event’
  • ‘button_release_event’
  • ‘draw_event’
  • ‘key_press_event’
  • ‘key_release_event’
  • ‘motion_notify_event’
  • ‘pick_event’
  • ‘resize_event’
  • ‘scroll_event’
  • ‘figure_enter_event’,
  • ‘figure_leave_event’,
  • ‘axes_enter_event’,
  • ‘axes_leave_event’
  • ‘close_event’

For the location events (button and key press/release), if the mouse is over the axes, the variable event.inaxes will be set to the Axes the event occurs is over, and additionally, the variables event.xdata and event.ydata will be defined. This is the mouse location in data coords. See KeyEvent and MouseEvent for more info.

Return value is a connection id that can be used with mpl_disconnect().

Usage:

def on_press(event):
    print('you pressed', event.button, event.xdata, event.ydata)

cid = canvas.mpl_connect('button_press_event', on_press)
mpl_disconnect(cid)

Disconnect callback id cid

Usage:

cid = canvas.mpl_connect('button_press_event', on_press)
#...later
canvas.mpl_disconnect(cid)

start_event_loop(timeout=0)

Start a blocking event loop.

Such an event loop is used by interactive functions, such as ginput and waitforbuttonpress, to wait for events.

The event loop blocks until a callback function triggers stop_event_loop, or timeout is reached.

If timeout is negative, never timeout.

Only interactive backends need to reimplement this method and it relies on flush_events being properly implemented.

Interactive backends should implement this in a more native way.

__init__()

Initialize self. See help(type(self)) for accurate signature.

__init__(widget, layout, size=450, ticks=30, show_status=True, show_counters=False, zoom_on_pick=True, dpi=100, multiselect=False)

Create a Rama object

Parameters:
  • widget (QWidget) – the PyQt widget that ‘owns’ this plot
  • layout (QLayout) – the layout to place the plot into
  • size (int) – size of square plot in pixels, (default=450).
  • dpi (int) – dots per inch resolution of plot (default=100).
  • size – unused, kept for backward compatibility
  • show_status (bool) – If True, cursor location feedback is given in the matplotlib toolbar
  • show_counters (bool) – If True, show controls for changing the Phi and Psi values of the selected dihedral. Only one of multiselect and show_counters can be True.
  • zoom_on_pick (bool) – If True, zoom the Maestro workspace to the dihedral picked
  • multiselect (bool) – If True, the user can pick multiple points with shift/cntl-click. If False (default), only one point can be picked at a time. Only one of multiselect and show_counters can be True.
draw_regions(filename='rama500-general.data')
find_connected_atom(ct, iatom, atname)

Return the atom index with PDB atom type atname attached to iatom in ct, or -1 if no connection is found.

get_connected_pair(ct, iatom, at1name, at2name)

Return a pair of atom indexes, where at1name is attached to iatom and at2name is attached to at1name.

get_weight_symbol(weight)
update_point_faces(indexes)

Update the face colors for points on the plot - faster than doing a complete replot.

Parameters:indexes (list) – List of indexes to recolor. Should be the index of the point in the self.dihedral_list list
update_point_xval(index, xval)

Update the x-value of a point on the plot

Parameters:index (int) – The index of the point in the self.dihedral_list list
update_point_yval(index, yval)

Update the y-value of a point

Parameters:index (int) – The index of the point in the self.dihedral_list list
update_display()
display_structure(ct, CA_list=[])
save()

Store the current phi & psi values of the current point.

This method only makes sense with multiselect == False

revert_to_original()

Set the current point to its original phi & psi values

This method only makes sense with multiselect == False

revert_to_saved()

Set the current point to its previously saved phi & psi values

This method only makes sense with multiselect == False

display_residue(which='all')

Select residues in the workspace corresponding to the given points

Parameters:which (int, None or 'all') – If None, all residues are deselected. If an integer, that integer is taken as the index in the dihedral list to select. If ‘all’, residues for all selected points are selected.
adjust_phi(value)

React to changed value of the Phi spinbox

The method only makes sense with multiselect == False

Parameters:value (float) – new value of the spinbox
adjust_psi(value)

React to changed value of the Psi spinbox

The method only makes sense with multiselect == False

Parameters:value (float) – new value of the spinbox
apply_dihedral(idihedral)

Change the value of a dihedral

Parameters:idihedral (int) – The index of the dihedral to change
minus(event)
plus(event)
clear_selection(event)

Clear the selected points

Parameters:event (event or None) – The event that generated this call, or None if not being called as a response to an event. This parameter is unused.
drag(event)

As the user moves the mouse over a point, display information for that point in the toolbar and select the corresponding residue in the workspace.

Parameters:event (matplotlib MouseEvent) – The event that generated the call to this method.
change_current_pick(new_pick, multi=False)
find_closest_point(event)

Find the plot point that is closest to the event

Parameters:event (MouseEvent) – The matplotlib mouse event that generates this call
pick_by_point(event)
pick_by_atom(iatom)
get_picked()

Get the backbone_dihedral object for the selected dihedral that was most recently selected.

Return type:backbone_dihedral object or None
Returns:The backbone_dihedral object for the selected dihedral that was most recently selected, or None if there are no selected dihedrals.
