Hi Mates,
I’ve got one Segmentation fault when I did a pointer release over one QGraphicsWebView instance, this only happens when
QWebSettings::PluginsEnabled is enabled.
Also the way to load the HTML could be considered, I’m using a piece of html to renderize SWF files, next snippet
of code shows how swf file is filled into this html
url = QUrl::fromLocalFile(m_path);
QString html = FLASH_PAGE_CONTENT;
html = html.replace(“WIDTH”, QString::number(m_item->preferredSize().toSize().width()));
html = html.replace(“HEIGHT”, QString::number(m_item->preferredSize().toSize().height()));
html = html.replace(“FLASHFILE”, url.toString());
m_item->setHtml(html);
FLASH_PAGE_CONTENT is something like that
“”“
#ifndef FLASH_PAGE_CONTENT
#define FLASH_PAGE_CONTENT \
“<html>” \
“<head>” \
“<style type=‘text/css’>” \
“html, body, div { margin: 0; border: 0 none; padding: 0; height: 100%; min-height: 100%; background-color:transparent;}” \
“</style>” \
“</head>” \
“<body><div>” \
“<embed src=‘FLASHFILE’ id=‘flash’ quality=‘high’ scale=‘exactfit’ “ \
“width=‘WIDTH’ height=‘HEIGHT’ name=‘flash’ align=‘middle’ “ \
“allowscriptaccess=‘always’ type=‘application/x-shockwave-flash’ “ \
“pluginspage=‘http://www.macromedia.com/go/getflashplayer’/>” \
“</div></body>” \
“</html>”
#endif
“”“
m_item is allocated at WebItem constructor [see bt], and it can be allocated n times along of time and released n
time alog of the tiem as well. But currently the release of m_item pointer is raising a Segfault, see next back trace at
pastebin url.
