[Split] Problems with Qt Creator/Designer plugins
I see. Thank you for clarifying that for me. This brings me back to my earlier issue with making plugins for designer. Since the topic name is quite broad, i won't open up another for my plugin problems. I have two problems:
First one is invisible widgets: I have made a plugin class for the widget i described before(obviously not properly) and packaged it up into a shared library and copied it into two folders of the Qt SDK installation(in my case /opt/QtSDK/Desktop/Qt/473/gcc/lib and /opt/QtSDK/QtCreator/lib/qtcreator/plugins/designer/). The widget shows up properly, but when I drag and drop it to the form, it's just an invisible box.
Second problem is with the widget that needs a graph. I used Qwt library for making it, and best I've managed at integrating it into designer is to crash it completely whenever I start it up from the creator.

You'll have to show us the source code (or upload it somewhere). You could also try to recompile Qt Creator, that's an issue sometimes.

Just split off the question in a separate topic, as it was only loosely related to the "original thread":http://developer.qt.nokia.com/forums/viewthread/7092/
Okay. The source for the first one(invisibility problem) is here:
The resulting lib I then manually copy to the locations I mentioned in the earlier post.
The source for the second one(segmentation fault -> creator/designer crash) is here:
Again, the resulting libQtCAgraph.so is copied in those two destinations.
OK, an update to my problem: by commenting out all delete statements in the destructor for the widget it works and doesn't crash anymore. Even though I have somewhat of a sloppy class, it kindof works. It occurs to me that before I began to plugin-ise the widget I encountered the same thing somewhere around the delete statement for the plot or curve object in the destructor.
