Description Samuel Mehrbrodt (allotropia) 2022-11-21 07:50:51 UTC
1. Open Writer
2. File->Export As->Export as PDF
3. Enable "Universal Accessibility (PDF/UA)
4. Export

-> Accessibility Check dialog appears

Expected: Any of the buttons in the dialog can be clicked

Actual: Buttons not clickable

Works with gen, doesn't work with gtk3.

Problem since 1409159d6117d49e61fe5369f858239ff259fc1e
Comment 1 Caolán McNamara 2022-11-21 17:06:10 UTC
On the other hand with "gen" I can create multiple accessibility check dialogs by repeatedly pressing "export" in the underlying dialog, and then dismiss the underlying pdf dialog, at which point clicking ok or cancel in an accessibility check dialog will crash.

Do we really want it modeless when it's a child of this modal pdf dialog? We could just have it modal (and a child of the pdf dialog instead of a child of the pdf dialog's parent) in this case and sidestep the question: https://gerrit.libreoffice.org/c/core/+/143044

hopefully that's "good enough"
