You can listen to the check event on the checkbox. Then you would have to resolve the combobox from that listener to take the appropriate action on the combobox.

xtype: 'form',
items: [{
xtype: 'checkbox',
ref: 'myCheckbox'
listeners: {
check: function (checkbox, isChecked) {
}, {
xtype: 'combo',
ref: 'myCombo',

Something like that. You can avoid the inline listeners option if you so desire. Grab the form after it's instantiated and

form.myCheckbox.on('check', function (checkbox, isChecked) {
}, form);
