Python imports into namespaces.

Python doesn't reexecute already-imported modules, so that is right.

#-- Here it is all in one file:
import dabo
dabo.ui.loadUI("wx")
class MyTestDialog(dabo.ui.dDialog):
pass
class MyMainForm(dabo.ui.dForm):
def afterInit(self):
self.addObject(dabo.ui.dButton, Caption="Hit Me",
OnHit=self.onButtonHit)
def onButtonHit(self, evt):
dlg = MyTestDialog()
dlg.show()
dlg.release()
if __name__ == "__main__":
app = dabo.dApp(MainFormClass=MyMainForm)
app.start()
## - end example one.
In the following example, we split MyTestDialog and MyMainForm into
their own files, so there are 3 files (main.py, MyTestDialog.py, and
MyMainForm.py)
##- Begin main.py
import dabo
import MyMainForm
app = dabo.dApp(MainFormClass=MyMainForm.MyMainForm)
app.start()
##- End main.py
##- Begin MyTestDialog.py
import dabo
dabo.ui.loadUI("wx")
class MyTestDialog(dabo.ui.dDialog):
pass
## - End MyTestDialog.py
## - Begin MyMainForm.py
import dabo
import MyTestDialog
dabo.ui.loadUI("wx")
class MyMainForm(dabo.ui.dForm):
def afterInit(self):
self.addObject(dabo.ui.dButton, Caption="Hit Me",
OnHit=self.onButtonHit)
def onButtonHit(self, evt):
dlg = MyTestDialog.MyTestDialog()
dlg.show()
dlg.release()
##- End MyMainForm.py
Notice how each file needed to import stuff that may have been imported
already in another of the files.

Not that I know of.
