RE: can't see epicsqt widgets in QT designer

Hi Hansen

In Designer you can have a look in 'Help->About Plugins'. If Designer has found the plugin library, but is not happy loading it it will usually list the plugin in the list and note what problem it had with it. For example, under windows it may state that it can't use a plugin built in debug with others built in release mode mode.

What you have done - set QT_PLUGIN_PATH is a simple and very robust way to point to plugin libraries, (but it does need to point to the 'designer' directory containing the plugin - which you appear to do correctly).

There are however other ways for Designer to locate you plugin library, such as copy the plugin library to same directory as Designer's other plugins.

http://qt-project.org/doc/qt-5/deployment-plugins.html i think contains the definitive rules Designer uses for locating plugins.

http://canvoki.net/Codders/qtpluginnotloading.html lists quite a few reasons why plugins don't load, which may also help.

Are you sure the QT_PLUGIN_PATH environment variable is defined when Designer runs?

Can you launch Designer from the same environment for which you can run the following command?

$ ls $QT_PLUGIN_PATH/designer

libQEPlugin.so

Regards

Andrew

Subject: can't see epicsqt widgets in QT designer

Hi,

QE framework already compile successfully and can see QWT widgets in QT designer.

The QT_PLUGIN_PATH set to "/$epicsqt_root/framework" but still can't see any epicsqt widgets in QT designer.

Anybody can help me to analyse what is the reason?
