Pessoal podiam ajudar nas seguintes dúvidas sobre openlayers?
Como fixar o zoom com base numa unica layer de modo a que não seja
possivel mover o mapa para além desse mesmo layer?Mesmo que exista
outros com áreas superiores.
Adicionando layer como wms/png é possível depois editar (como vectores)
e adicionar eventos com base em mouse events?
Devido a ter muitas camadas parte do layer switcher fica oculto como
posso resolver este problema sem ter de aumentar ao tamanho da pagina?é
possivel fixar-lo no canto superior esquerdo?(mais para cima) e colocar
o tamanho das letras mais pequeno?
Como posso ajustar automaticamente o tamanho da janela do openlayers ao
tamanho da pagina?
Obrigado
