Hi Kyle!
The python code to get all the id's looks like this:
ids = []
for feat in iface.activeLayer().getFeatures():
ids.append(feat.id())
print(ids)
Now you need to connect your button to a function containing the above
code, something like:
Hi!
im from Brazil!
I made a form, using QT4 (here we r using qgis 2.18 yet), on this form, i
put a button that must take all "id" from selected features in a selected
Layer.
How to do it???
