[Pyobjc-dev] different behaviour for NSView.drawRect_

[Frederik B. <fre...@ty...>]

Hi!

I noticed different behaviour of macOS calling my nsView subclass drawRect_ method, when I run a script  directly in terminal or from within my app: DrawBot (http://www.drawbot.com <http://www.drawbot.com/>)

The python version and installed packages are the same, the most current ones from pip.

The window is build with vanilla (a pythonic cocoa wrapper) https://github.com/typesupply/vanilla <https://github.com/typesupply/vanilla>



When this script is executed inside DrawBot: I get, based on my screen (retina or an old cinema HD), lots of drawRect_ callback with fixed width and height.

When executed in no-app world, terminal: I get a single callback on my drawRect_ with the size of the visible rect.

I fully understand the difference in performance and why this is happening.


BUT:

Im unable to toggle between those two settings. I don't know what or where I have to change a setting to get a specific behaviour:  
* tilled drawRect_ callbacks
* a visible rect drawRect callback



please point me in the right direction

(If this question is posted in the wrong place, I happily repost it elsewhere)

thanks
