[Qgis-developer] Creating a new QgsComposerHtml from Python causes segmentation fault

[Akbar Gumbira]

Hi,

When we call getComposerItemById, it will return QgsComposerItem, which can
be many things: QgsComposerLabel, QgsComposerLegend, QgsComposerFrame,
QgsComposerPicture, etc. In case of the item is html frame, it will return
QgsComposerFrame. Unlike other items that you can get the component
directly, to get the QgsComposerHTML itself you should do:

html_item = mycomp.getComposerItemById('myhtml')
composer_html = mycomp.getComposerHtmlByItem(html_item)

Regards
