Demo - Compact Layouts and Element Renaming
|
|
|
|
Some layouts contain many many elements such that space becomes a premium. For experienced PySimpleGUI
|
|
programmers, there is little additional knowledge to be gained by writing
|
|
sg.Text('My text')
|
|
rather than using one of the shortcuts such as
|
|
sg.T('My text')
|
|
However, even with shortcut usage, you continue to have the package prefix of
|
|
sg.
|
|
That's 3 characters per element that are added to your layout!
|
|
The very long import statement st the top can be copied into your code to give you the ability to write
|
|
T('My text')
|
|
|
|
If you don't want to use that very-long import or perhaps want to use your own shortcut names, you can easily
|
|
create your shortcut by simple assignment:
|
|
T = sg.Text
|
|
This enables you to use T just as if you imported the Class T from PySimpleGUI. You could develop your own
|
|
template that you copy and paste at the top of all of your PySimpleGUI programs. Or perhaps perform an import
|
|
of those assignments from a .py file you create.
|
|
|
|
Note that you may lose docstrings in PyCharm using these shortcuts. You can still see the parameters when pressing
|
|
Control+P, but the Control+Q doesn't bring up the full list of parms and their descriptions. Looking for a fix
|
|
for this.
|
|
|
|
PLEASE OH PLEASE OH PLEASE NEVER EVER EVER do this:
|
|
from PySimpleGUI import *
|
|
There is a bot scanning GitHub for this statement. If found in your code, a squad of assassins will be dispatched
|
|
from the PySimpleGUI headquarters and you will be hunted down and forced to change your code.
