    <p>Though some people have helped open a file, I understand you are actually looking to import a text file as a map: I did not write this, but have been using it as an example for my game:</p> <pre><code># This code is in the Public Domain # -- richard@mechanicalcat.net class Map: def __init__(self, map, tiles): self.tiles = pygame.image.load(tiles) l = [line.strip() for line in open(map).readlines()] self.map = [[None]*len(l[0]) for j in range(len(l))] for i in range(len(l[0])): for j in range(len(l)): tile = l[j][i] tile = tile_coords[tile] if tile is None: continue elif isinstance(tile, type([])): tile = random.choice(tile) cx, cy = tile if random.choice((0,1)): cx += 192 if random.choice((0,1)): cy += 192 self.map[j][i] = (cx, cy) def draw(self, view, viewpos): '''Draw the map to the "view" with the top-left of "view" being at "viewpos" in the map. ''' sx, sy = view.get_size() bx = viewpos[0]/64 by = viewpos[1]/64 for x in range(0, sx+64, 64): i = x/64 + bx for y in range(0, sy+64, 64): j = y/64 + by try: tile = self.map[j][i] except IndexError: # too close to the edge continue if tile is None: continue cx, cy = tile view.blit(self.tiles, (x, y), (cx, cy, 64, 64)) def limit(self, view, pos): '''Limit the "viewpos" variable such that it defines a valid top-left rectangle of "view"'s size over the map. ''' x, y = pos # easy x = max(x, 0) y = max(y, 0) # figure number of tiles in a view, hence max x and y viewpos sx, sy = view.get_size() nx, ny = sx/64, sy/64 mx = (len(self.map[0]) - nx) * 64 my = (len(self.map) - ny) * 64 print y, my return (min(x, mx), min(y, my)) def main(): pygame.init() win = pygame.display.set_mode((640, 480)) map = Map('map.txt', 'tiles.png') viewpos = (0,0) move = False clock = pygame.time.Clock() sx, sy = win.get_size() while 1: event = pygame.event.poll() while event.type != NOEVENT: if event.type in (QUIT, KEYDOWN): sys.exit(0) elif event.type == MOUSEBUTTONDOWN: x, y = viewpos dx, dy = event.pos x += dx - sx/2 y += dy - sy/2 viewpos = map.limit(win, (x, y)) move = True event = pygame.event.poll() win.fill((0,0,0)) map.draw(win, viewpos) pygame.display.flip() clock.tick(30) if __name__ == '__main__': main() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
