I am trying to make a web browser using pygame. I am using PGU for html rendering. It works fine when I visit simple sites, like example.com, but when I try and load anything more complex that uses an html form, like google, I get this error:
UnboundLocalError: local variable 'e' referenced before assignment
I looked in the PGU html rendering file and found this code segment:
def start_input(self,attrs):
r = self.attrs_to_map(attrs)
params = self.map_to_params(r) #why bother
#params = {}
type_,name,value = r.get('type','text'),r.get('name',None),r.get('value',None)
f = self.form
if type_ == 'text':
e = gui.Input(**params)
self.map_to_connects(e,r)
self.item.add(e)
elif type_ == 'radio':
if name not in f.groups:
f.groups[name] = gui.Group(name=name)
g = f.groups[name]
del params['name']
e = gui.Radio(group=g,**params)
self.map_to_connects(e,r)
self.item.add(e)
if 'checked' in r: g.value = value
elif type_ == 'checkbox':
if name not in f.groups:
f.groups[name] = gui.Group(name=name)
g = f.groups[name]
del params['name']
e = gui.Checkbox(group=g,**params)
self.map_to_connects(e,r)
self.item.add(e)
if 'checked' in r: g.value = value
elif type_ == 'button':
e = gui.Button(**params)
self.map_to_connects(e,r)
self.item.add(e)
elif type_ == 'submit':
e = gui.Button(**params)
self.map_to_connects(e,r)
self.item.add(e)
elif type_ == 'file':
e = gui.Input(**params)
self.map_to_connects(e,r)
self.item.add(e)
b = gui.Button(value='Browse...')
self.item.add(b)
def _browse(value):
d = gui.FileDialog();
d.connect(gui.CHANGE,gui.action_setvalue,(d,e))
d.open();
b.connect(gui.CLICK,_browse,None)
self._locals[r.get('id',None)] = e
I got the error in the last line, because e wasn't defined. I am guessing the reason for this is that the if statement that checks the type of the input and creates the e variable didn't match anything. I added a line to print the _type variable and I got 'hidden' when i tried google and apple. Is there any way to render form items that have the type 'hidden' with PGU?
