class timelinelib.canvas.drawing.drawers.ballondrawer.BallonDrawer

Bases: object

__init__(dc, scene, appearance, event)

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

draw(event_rect, sticky)

Draw one ballon on a selected event that has ‘description’ data.

get_icon_size()

max_text_width(event_rect, icon_width)

get_description_lines(max_text_width, iw)

calc_inner_rect(lines, w, h, max_text_width)

draw_balloon_bg(inner_size, tip_pos, above, sticky)

Draw the balloon background leaving inner_size for content.

tip_pos determines where the tip of the ballon should be.

above determines if the balloon should be above the tip (True) or below (False). This is not currently implemented.

Calculation of points starts at the tip of the arrow and continues clockwise around the ballon.

Return (bounding_rect, x, y) where x and y is at top of inner region.

timelinelib.canvas.drawing.drawers.ballondrawer.break_text(text, dc, max_width_in_px)

Break the text into lines so that they fits within the given width.

timelinelib.canvas.drawing.drawers.ballondrawer.break_sentence(dc, lines, sentence, max_width_in_px)

Break a sentence into lines.

timelinelib.canvas.drawing.drawers.ballondrawer.break_line(dc, sentence, max_word_len_in_ch)

Break a sentence into words.

timelinelib.canvas.drawing.drawers.ballondrawer.break_word(dc, word, max_word_len_in_ch)

Break words if they are too long.

If a single word is too long to fit we have to break it. If not we just return the word given.
