Bug ID: 518537
Summary: HTML preview shows raw source instead of rendered HTML
Classification: Applications
Product: kate
Version First 25.08.1
Reported In:
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: part
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Root cause: KPartView::updatePreview() in addons/preview/kpartview.cpp creates
a QTemporaryFile with no file extension (line 211). The webenginepart
(Chrome-based) uses the file extension to detect the MIME
type of local file:// URLs. With no extension, it cannot identify the content
as text/html and displays it as plain text/source.
Fix: create the temp file with the MIME-derived extension:
const QString suffix =
QMimeDatabase().mimeTypeForName(m_document->mimeType()).preferredSuffix();
const QString tmpl = QDir::tempPath() +
QStringLiteral("/kate-preview-XXXXXX") + (suffix.isEmpty() ? QString() :
QLatin1Char('.') + suffix);
m_bufferFile = new QTemporaryFile(tmpl, this);
Tested: confirmed via strace that Kate creates /tmp/kate.XXXXXX (no
extension), and Konqueror (same webenginepart) correctly renders the same file
when opened directly with its .html extension.
