[Qt-interest] Qt-interest Digest, Vol 17, Issue 54

Fri Apr 9 11:27:53 CEST 2010

Hallo Andre,
I have some icons in my widgets(two buttons, 1 tree view), which are .gif
files.
I have Imported these gif to my resource file and I am accessing these
images from the resource.
Problem comes when I try to make an executable and run that executable in a
system which have no QT installed. when I run the executable, I can't see
the icons there.
I was trying to debug that, and I found out I need to specify to my
programme where to find plugin for .gif images. So I try to import these
plugin in my programme, and that where I encounter that error.

do you think is there any other way to either show the gif icon(somehow by
copying the gif file with code) or to specify gif plugins (*.dll) required
for my programme?

Is there a specific reason you use Q_IMPORT_PLUGIN? Do you have a static
Qt build?
