Question

嗨，大家好，我做了个嘘声！我做了一个微调器并填充它，然后想...我想把表格的颜色从黑色改为白色，所以我做了但是现在旋转器不在那里我不知道我做了什么！好吧，我有点做，我想我的代码在错误的地方，但我不确定正确的地方在哪里...... sooooo

到目前为止整个事情，我要在微调器下面调用一个按钮，调用FindIncident并在微调器中选择该工作站，按钮下方将是一个标签，用于发送te细节（而不是print）并且我希望在其下有另一个按钮，只有在找到该工作站才能打开网页中的网址时才会出现。

多数民众赞成要清楚大声笑我的问题是我在哪里可以看到微调器的代码可见？

我从头开始在表单上，没有意识到你必须将小部件添加到父窗口小部件

class DSFRSapp(App):
    def build(self):
        self.root = FloatLayout()
        i = Image(source='DSFRSLogo.png',

                  pos_hint = ({'center_x':0.5, 'y': .25}))
        spinner = Spinner(
text='Pick a Station',
values=('Appledore','Axminster','Bampton','Barnstaple','Bere Alston','Bideford','Bovey Tracey','Braunton','Bridgwater','Brixham','Buckfastleigh','Budleigh Salterton','Burnham on sea','Camels Head','Castle Cary','Chagford','Chard','Cheddar','Chulmleigh','Colyton','Combe Martin','Crediton','Crewkerne','Crownhill','Cullompton','Dartmouth','Dawlish','Exeter Danes Castle','Exeter Middlemoor','Exmouth','Frome','Glastonbury','Greenbank','Hartland','Hatherleigh','Holsworthy','Honiton','Ilfracombe','Ilminster','Ivybridge','Kingsbridge','Kingston','Lundy Island','Lynton','Martock','Minehead','Modbury','Moretonhampstead','Nether Stowey','Newton Abbot','North Tawton','Okehampton','Ottery St Mary','Paignton','Plympton','Plymstock','Porlock','Princetown','Salcombe','Seaton','Shepton Mallet','Sidmouth','Somerton','South Molton','Street','Taunton','Tavistock','Teignmouth','Tiverton','Topsham','Torquay','Torrington','Totnes','USAR','Wellington','Wells','Williton','Wincanton','Witheridge','Wiveliscombe','Woolacombe','Yelverton','Yeovil'),
