Bug ID: 384973
Summary: No preview for initially loaded document in Kate
Product: kate
Version: Git
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: plugin-preview
Assignee: kwrite-bugs-n...@kde.org
Reporter: kosse...@kde.org
CC: kosse...@kde.org
Depends on: 384448, 384449
Target Milestone: ---
The first document loaded into Kate does not get any preview. Both if loaded
via commandline argument or when selecting a file via the Open dialog.
Reason is that the plugin relies on the MIME type reported for the document.
Right now KTextEditor only estimates that MIME type on request instead of
maintaining this property itself and notifying clients about any changes (see
bugs this report depends on).
Kate reuses the initially shown empty document for loading the initial file
(unless the document was edited). So the preview plugin, which only updates on
new document objects currently, misses to learn about a new file being loaded.
Workaround:
Either close & open again the file or switch the preview plugin shortly to
preview another open document.
