Bug ID: 395186
Summary: Document.selection() returns None when selection
created by Action is still processing.
Product: krita
Version: 4.0.3
Platform: Appimage
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Scripting
Assignee: krita-bugs-n...@kde.org
Reporter: gbird...@gmail.com
Target Milestone: ---
Created attachment 113176
--> https://bugs.kde.org/attachment.cgi?id=113176&action=edit
File for testing
When I try to create selection from Action for example 'selectopaque' and then
fetch it with s = doc.selection() most of the time I will get s == None.
If I run the same code again when selection already exists doc.selection()
returns actual selection.
Steps:
1 Open Attached test file
2 Select layer with green circle
3 Run this script in Scripter
from krita import *
k = Krita.instance()
d = k.activeDocument()
def test_selection():
k.action('selectopaque').trigger()
s = d.selection()
if s == None:
print("Yes...")
else:
print("No O_O")
s.invert()
d.setSelection(s)
d.refreshProjection()
test_selection()
#test_selection()
Result:
Krita will creates selection from the green circle.
Scripter throws: AttributeError: 'NoneType' object has no attribute 'invert'
Expected result:
Krita creates selection from the green circle and inverts this selection.
4 Remove selection from the Image
5 Uncomment last line of the script so test_selection() will be run 2 times in
a row.
6 Run script again
Result:
As expected. Inverted selection from green circle.
